Objective:To compare the clinical efficacy and analyze the surgical approach differences using CT parameters between mini-open transforaminal lumbar interbody fusion (MO-TLIF) and minimally invasive surgery of transforaminal lumbar interbody fusion (MIS-TLIF) in the treatment of degenerative lumbar diseases.Methods:A total of 68 consecutive patients with degenerative lumbar diseases undergoing surgery at the Second Affiliated Hospital of Soochow University from January 2022 to January 2023 were randomized into the MO-TLIF group (34 cases, percutaneous screw-assisted posterior midline MO-TLIF) and the MIS-TLIF group (34 cases, Wiltse approach MIS-TLIF using the Quadrant channel). Perioperative indicators (operative time, incision length, intraoperative blood loss, fluoroscopy frequency, postoperative bedrest duration, and hospital stay) and complications were compared. Visual analogue scale (VAS) and Oswestry disability index (ODI) were assessed preoperatively and at 3 days, 3 months, and 1 year postoperatively. Effective cross-sectional area (eCSA) of paraspinal muscles was evaluated on MRI preoperatively and 1 year postoperatively. CT parameters of surgical approaches, including spinous process-midline distance (SM), Wiltse-midline distance (WM), surgical approach angle, depth, and multifidus muscle displacement were compared. Pearson correlation and multivariate linear regression analyses were performed to explore associations between CT parameters, operative time, blood loss, and eCSA atrophy.Results:Baseline characteristics showed no significant differences between groups ( P>0.05). The MO-TLIF group exhibited shorter operative time (109.85±7.82 min vs. 133.82±20.22 min), reduced blood loss (77.21±21.83 ml vs. 141.18±31.44 ml), smaller incision length (6.09±0.22 cm vs. 7.00±0.43 cm), shorter bedrest duration (1.59±0.49 d vs. 2.38±0.50 d), and shorter hospital stay (8.93±1.44 d vs. 10.35±1.45 d), but higher fluoroscopy frequency (19.53±1.92 times vs. 16.29±1.78 times) compared to the MIS-TLIF group ( P<0.05). Complications included fat liquefaction (5 cases) and dural tears (2 cases). Both groups showed improved VAS and ODI postoperatively ( P<0.05). At 3 d postoperatively, the MO-TLIF group had lower VAS (2.74±0.47 points vs. 3.35±0.48 points) and ODI (27.46%±2.16% vs. 30.42%±2.52%) than the MIS-TLIF group ( P<0.05). Postoperative eCSA decreased significantly in the MIS-TLIF group ( P<0.05) but remained stable in the MO-TLIF group ( P>0.05). The MO-TLIF group demonstrated smaller SM (8.43±1.81 mm vs. 31.15±6.53 mm), approach angle, depth, and muscle displacement ( P<0.05). CT parameters in the MO-TLIF group showed no correlation with operative time, blood loss, or eCSA atrophy ( r<0.3, P>0.05), whereas parameters in the MIS-TLIF group correlated positively with these outcomes (0.3< r<0.6, P<0.05). Multivariate regression revealed a significant association between CT parameters and eCSA atrophy in the MIS-TLIF group ( R 2=0.474, P<0.05). Conclusion:Compared to MIS-TLIF, MO-TLIF reduces intraoperative blood loss, accelerates recovery, and minimizes paraspinal muscle trauma.

ObjectiveTo construct a group-based trajectory model (GBTM) for early medication adherence check-in, and to analyze the relationship between different trajectories and treatment outcomes in tuberculosis patients using data that were generated from smart tools for monitoring their medication adherence and check-in. MethodsFrom October 1, 2022 to September 30, 2023, a total of 163 pulmonary tuberculosis patients diagnosed in Fengxian District were selected as the study subjects. The GBTM was utilized to analyze the weekly active check-in trajectories of the subjects during the first 4 weeks and establish different trajectory groups. The χ² tests were employed to compare the differences between groups and logistic regression analysis was conducted to explore the relationship between different trajectory groups and treatment outcomes. ResultsA total of four groups were generated by GBTM analyses, of which a low level of punch card was maintained in group A, 6% of the drug users increased rapidly from a low level in group B, 17% of drug users increased gradually from a low level in group C, and 18% of drug users maintained a high level of punch card in group D. The trajectory group was divided into two groups according to homogeneity, namely the low level medication punch card group (group A) and the high level medication punch card group (group B, group C, and group D). The results of multivariate logistic regression analyses revealed that low-level medication check-in (OR=3.250, 95%CI: 1.089‒9.696), increasing age (OR=1.030, 95%CI: 1.004‒1.056), and not undergoing sputum examination at the end of the fifth month (OR=2.746, 95%CI: 1.090‒7.009) were significantly associated with poor treatment outcomes. ConclusionThe medication check-in trajectory of pulmonary tuberculosis patients within the first 4 weeks is correlated with adverse outcomes, or namely consistent low-level medication adherence check-ins are associated with poor treatment outcomes, while high-level medication adherence check-ins are associated with a lower incidence of adverse outcomes.

Objective To explore the effect of community pharmacy outpatient service on patients with type 2 diabetes mellitus. Methods A non-randomized controlled study was conducted, and type 2 diabetes patients managed in the community were divided into an intervention group of 112 cases and a control group of 110 cases. The control group received routine medication guidance during general practice outpatient visits, while the intervention group received comprehensive pharmacy outpatient service intervention based on routine medication guidance in general practice. Follow-up visits were conducted every 3 months. Repeated measurement analysis of variance and multivariate linear regression analysis were used to evaluate the intervention effect of the pharmacy outpatient service. Results Fasting blood glucose and glycosylated hemoglobin levels in the intervention group showed a decreasing trend with the increase of intervention time compared to pre-intervention time （P<0.01）, with increased duration of weekly exercise, decreased staple food intake, increased vegetable intake, and increased medication adherence score （P<0.01）. After adjusting for confounding factors through multivariate linear regression model, pharmacy outpatient intervention was found to be an independent protective factor for fasting blood glucose level （β=−0.891, P<0.01） and glycosylated hemoglobin level （β=−0.760, P<0.01） in the study subjects. Conclusion The community pharmacy outpatient service could enhance the self-management ability of patients with type 2 diabetes mellitus, and effectively improve patients’ fasting blood glucose and glycosylated hemoglobin.

ObjectiveTo find out whether there is any difference in the monitoring results of mosq-ovitraps placed in different orientations in multi-storey residential areas, so as to provide a scientific basis for routine and emergency monitoring of Aedes albopictus with mosq-ovitraps in residential areas. MethodsFrom July 6th to October 26th 2023, one mosquito ovitrap was set up in each of the 4 orientations of east, south, west and north around the buildings in a multi-storey residential area in Jinhui Town, Fengxian District, Shanghai. Data was collected and recorded 72 hours after placement. The chi-square test was used to compare the mosquito ovitrap indices (MOIs) of two independent samples, and the Kruskal⁃Wallis H test was used to compare the MOIs of multiple independent samples. ResultsAfter 16 weeks of surveillance, 997 mosquito ovitraps were recovered, of which 211 were positive, with the mosquito ovitrap index (MOI) of 21.16% and the Aedes albopictus density index of 1.03 mosquitoes·ovitrap^-1. The MOIs were higher in September (24.22%) and October (23.96%), and the MOIs in the west, south and north within the two months were all above 20.00%. From July to October, the MOIs in the east, west, south and north were 20.70%, 22.20%, 25.50% and 16.20%, respectively, and the difference in MOIs among the 4 orientations was not statistically significant (χ²=6.647, P=0.084). Stratified analysis by month showed that in August, the south side of the multi-storey residential areas had the highest MOI (31.30%), the north side had the lowest MOI (1.30%), and there was a statistically significant difference in MOI in the east, west, south and north (χ²=25.986, P<0.001). In October, the MOI in the west was the highest (33.30%) and the MOI in the east was the lowest (6.30%), the difference in MOIs of the 4 orientations was statistically significant (χ²=12.007, P=0.007). The MOIs in the south side of the building in the outskirts of the residential area from the 1st week in July to the 4th week in October was lower (19.20%) than that in the south side of the inner building (31.70%), and the difference in MOI was statistically significant (χ²=5.118, P=0.024). ConclusionThe study of MOI in different orientations in a multi-storey residential area is a preliminary exploration based on field work, and the results show that there is a difference in MOIs in different orientations during the peak breeding period of mosquitoes. Further indicators such as temperature, humidity and wind speed in different orientations can be collected to explore the influencing factors of MOIs.

Visual analogue scale (VAS) and Oswestry disability index (ODI) were assessed preoperatively and at 3 days, 3 months, and 1 year postoperatively. Effective cross-sectional area (eCSA) of paraspinal muscles was evaluated on MRI preoperatively and 1 year postoperatively. CT parameters of surgical approaches, including spinous process-midline distance (SM), Wiltse-midline distance (WM), surgical approach angle, depth, and multifidus muscle displacement were compared. Pearson correlation and multivariate linear regression analyses were performed to explore associations between CT parameters, operative time, blood loss, and eCSA atrophy.Results:Baseline characteristics showed no significant differences between groups ( P>0.05). The MO-TLIF group exhibited shorter operative time (109.85±7.82 min vs. 133.82±20.22 min), reduced blood loss (77.21±21.83 ml vs. 141.18±31.44 ml), smaller incision length (6.09±0.22 cm vs. 7.00±0.43 cm), shorter bedrest duration (1.59±0.49 d vs. 2.38±0.50 d), and shorter hospital stay (8.93±1.44 d vs. 10.35±1.45 d), but higher fluoroscopy frequency (19.53±1.92 times vs. 16.29±1.78 times) compared to the MIS-TLIF group ( P<0.05). Complications included fat liquefaction (5 cases) and dural tears (2 cases). Both groups showed improved VAS and ODI postoperatively ( P<0.05). At 3 d postoperatively, the MO-TLIF group had lower VAS (2.74±0.47 points vs. 3.35±0.48 points) and ODI (27.46%±2.16% vs. 30.42%±2.52%) than the MIS-TLIF group ( P<0.05). Postoperative eCSA decreased significantly in the MIS-TLIF group ( P<0.05) but remained stable in the MO-TLIF group ( P>0.05). The MO-TLIF group demonstrated smaller SM (8.43±1.81 mm vs. 31.15±6.53 mm), approach angle, depth, and muscle displacement ( P<0.05). CT parameters in the MO-TLIF group showed no correlation with operative time, blood loss, or eCSA atrophy ( r<0.3, P>0.05), whereas parameters in the MIS-TLIF group correlated positively with these outcomes (0.3< r<0.6, P<0.05). Multivariate regression revealed a significant association between CT parameters and eCSA atrophy in the MIS-TLIF group ( R 2=0.474, P<0.05). Conclusion:Compared to MIS-TLIF, MO-TLIF reduces intraoperative blood loss, accelerates recovery, and minimizes paraspinal muscle trauma.

Objective:To evaluate the clinical efficacy of Sanren Decoction combined with triple therapy in the treatment of Hp-related chronic atrophic gastritis (CAG).Methods:A randomized controlled trial was conducted. A total of 118 patients with Hp-related CAG admitted to Department of Spleen and Stomach Diseases of Xi'an Affiliated Hospital of Shaanxi University of Chinese Medicine from February 2021 to February 2023 were selected as observation subjects, and were divided into two groups according to random number table method, with 59 cases in each group. The control group received triple therapy (amoxicillin+clarithromycin+omeprazole), whereas the observation group was combined with modified Sanren Decoction on the basis of the control group. Both groups were continuously treated for 10 days. TCM symptoms were scored before and after treatment. Updated Sydney System (UAS) was applied to evaluate the gastric mucosal lesions. ELISA was applied to detect serum levels of cluster of differentiation 47 (CD47), VEGF and pepsinogenⅠ/pepsinogen Ⅱ (PGⅠ/PGⅡ). The Hp infection status was evaluated by Urea Breath Test (UBT). In addition, the adverse reactions were observed and recorded during treatment.Results:After treatment, the scores of gastric fullness, stomachache, acid reflux and bitter taste in observation group were lower than those in the control group ( t=4.52, 3.46, 4.34, 4.83, P<0.01), and the scores of gastric mucosal inflammation, atrophy, intestinal metaplasia and dysplasia were also lower compared to control group ( t=3.68, 2.88, 3.73, 4.45, P<0.01 or P<0.05). After treatment, the levels of serum CD47 [(4.46±1.29) μg/L vs. (5.01±1.37) μg/L, t=2.25] and VEGF [(70.53±10.47) ng/L vs. (79.34±10.56) ng/L, t=4.55] in observation group were lower ( P<0.05 or P<0.01), while the level of PGⅠ/PGⅡ [(12.45±1.78) vs. (10.82±1.62), t=5.20] was higher compared with that of the control group ( P<0.01). After treatment, the negative conversion rate of Hp was 96.61% (57/59) in observation group and that in control group was 81.36% (48/59) ( χ2=7.00, P=0.008). During treatment, the incidence of adverse reactions was 23.73% (14/59) in observation group and 15.25% (9/59) in control group, revealing no statistical significance between the two groups ( χ2=1.35, P=0.245). Conclusion:Modified Sanren Decoction combined with triple therapy can improve gastric mucosal lesions, reduce serum CD47 and VEGF levels, and increase PGⅠ/PGⅡ ratio and Hp negative conversion rate in patients with Hp-related CAG, with good safety.

This study aims to obtain highly sensitive and specific monoclonal antibodies to ribavirin.Ribavirin was coupled with carrier proteins to synthesize artificial complete antigen by glutaralde-hyde method.UV scanning,gel electrophoresis and animal immunization were employed to identify quality of the synthesized artificial complete antigens.The monoclonal antibody was prepared by cell fusion,positive hybridoma screening and induction of ascites in vivo,and the immunological characteristics of monoclonal antibodies were identified.The results showed that RBV was coupled to carrier proteins,and the artificial antigens were prepared successfully.One cell line that can stably secrete monoclonal antibodies against ribavirin was obtained,and the titers of the mono-clonal antibodies secreted by cell line was above 1∶512 000,with IC50 values of 4.74 μg/L.Fur-thermore,there were no cross-reactivity with other antiviral drugs such as amantadine and carrier proteins.In this study,monoclonal antibodies of ribavirin with high sensitivity and specificity was synthesized successfully,which lays a solid foundation for the establishment of immunoassay methods of ribavirin.

Objective:To investigate the application effect of Precede-Proceed model nursing in postoperative anti-osteoporosis treatment of patients with osteoporotic thoracolumbar fracture (OTLF).Methods:A retrospective cohort study was conducted to analyze the clinical data of 168 patients with OTLF admitted to the Second Affiliated Hospital of Soochow University from September 2021 to June 2022, including 32 males and 136 females, aged 56-81 years [(72.0±6.6)years]. The fractured segments were T 1-T 10 in 29 patients, T 11-L 2 in 114 and L 3-L 5 in 25, all of whom were treated with percutaneous kyphoplasty (PKP). The 86 patients admitted from September 2021 to January 2022 were treated with conventional care (conventional nursing group) and the 82 patients admitted from February to June 2022 with Precede-Proceed model care (Precede-Proceed model nursing group). The compliance rates of anti-osteoporosis treatment at 1 and 6 months postoperatively and at the last follow-up were compared between the two groups, mainly including standardized medication, balanced diet, exercise and regular return visit. Chinese Osteoporosis Quality of Life (COQOL) questionnaire, including pain degree, physical function, social interaction ability, psychological and mental function, and total score were assessed before, at 6 months after surgery and at the last follow-up. Bone mineral density was measured preoperatively and at the last follow-up. Recurrence rate was recorded at the last follow-up. Results:All the patients were followed up for 12-16 months [(13.2±1.0)months]. There were 3 patients in the conventional nursing group and 2 in the Precede-Proceed model nursing group who were lost to follow-up. The compliance rates of standardized medication and regular return visit at 1 month after surgery were 97.5% (78/80) and 98.8% (79/80) in the Precede-Proceed model nursing group, which had no significant difference compared with 90.3% (75/83) and 96.4% (80/83) in the conventional nursing group ( P>0.05). The compliance rates of balanced diet and exercise at 1 month after surgery were 92.5% (74/80) and 91.3% (73/80) in the Precede-Proceed model nursing group, which were higher than those in the conventional nursing group [78.3% (65/83) and 73.5% (61/83)] ( P<0.05 or 0.01). The compliance rates of standardized medication, balanced diet, exercise and regular return visit at 6 months after surgery were 86.3% (69/80), 83.8% (67/80), 82.5% (66/80) and 90% (72/80) in the Precede-Proceed model nursing group, which were higher than those in the conventional nursing group [57.8% (48/83), 60.2% (50/83), 38.6% (32/83) and 37.3% (31/83)] ( P<0.01). At the last follow-up, the compliance rates of all the aspects in the Precede-Proceed model nursing group were 80% (64/80), 75% (60/80), 70% (56/80) and 82.5% (66/80), which were all higher than those of the conventional nursing group [36.1% (30/83), 54.2% (45/83), 26.5% (22/83) and 27.7% (23/83)] ( P<0.01). There were no statistical differences in COQOL scores including pain degree, physical function, social interaction ability, psychological and mental function and total scores between the two groups before surgery ( P>0.05). The pain degree, social interaction ability, psychological and mental function and total scores of COQOL in the Precede-Proceed model nursing group were lower than those in conventional nursing group at 6 months after surgery and at the last follow-up ( P<0.05 or 0.01). There was no statistical difference in the physical function of COQOL scores at 6 months after surgery ( P>0.05). The physical function of COQOL scores in the Precede-Proceed model nursing group were significantly lower than that of the conventional nursing group at the last follow-up ( P<0.05). There was no statistical difference in preoperative bone mineral density between the two groups ( P>0.05). Bone mineral density in the Precede-Proceed model nursing group was (-2.7±0.9)SD at the last follow-up, which was higher than that in the conventional nursing group [(-3.1±0.9)SD] ( P<0.05). At the last follow-up, bone mineral density of the Precede-Proceed model nursing group was significantly improved compared with that before surgery ( P<0.01), while there was no significant difference in the conventional nursing group ( P>0.05). The incidence of refracture in the Precede-Proceed model nursing group was 3.8% (3/80), which was lower than that in conventional nursing group [13.3% (11/83)] ( P<0.05). Conclusion:Compared with the conventional nursing mode, the Precede-Proceed model nursing can significantly improve the compliance rate of OTLF patients with postoperative anti osteoporosis treatment, improve their quality of life and bone quality, and reduce the incidence of refracture.

Objective To investigate the experience of intrauterine device(IUD)removal in patients with cervical cancer after radiotherapy.Methods A total of 23 patients with cervical cancer after radiotherapy underwent abdominal ultrasound guided hysteroscopic removal of IUD in our department from January 2020 to December 2022.For vaginal and/or cervical adhesions,blunt separation of adhesions was performed by using hysteroscope head or curved forceps under abdominal ultrasound guidance.If it was difficult to separate the adhesions for hysteroscope head entering the uterine cavity,a probe was inserted into the uterine cavity under ultrasound guidance,and the cervical canal was gradually expanded to 6-caliber dilation rod.Then the hysteroscope was inserted again into the uterine cavity.For obvious cervical atrophy that was tough in which cervical forceps could not be used to clamp the cervix,a 1-0 absorbable suture line was used to suture the anterior and/or posterior lips of the atrophied cervix at the top of the vagina,with an assistant firmly pulling and fixing the cervix.Results There were 4 cases of vaginal partial adhesions and cervical contracture,10 cases of cervical contracture,and remaining 9 cases having no vaginal adhesions and cervical contracture.Under hysteroscopy,there were 3 cases of cervical adhesions,2 cases of endometrial polyps,1 case of submucosal uterine fibroids,2 cases of uterine abscess,2 cases of incarcerated IUD,and remaining 13 cases having normal uterine cavity morphology.All the 23 cases of IUD were successfully removed by using abdominal ultrasound guided hysteroscopy(circular shaped in 12 cases,uterine shaped in 6 cases,V-shaped in 2 cases,Y-shaped in 1 case,T-shaped in 1 case,and umbrella shaped in 1 case).The surgical time was(19.2±10.9)min,and there were no complications such as false passage formation,uterine perforation,organ damage,massive vaginal bleeding,transurethral resection of the prostate syndrome,infection,embolism,or shock.The 23 cases were followed up for 2-24 months postoperatively,with a median of 12 months.One case continued concurrent radiotherapy and chemotherapy,3 cases continued post-loading radiotherapy,1 case continued chemotherapy,and 2 cases received targeted treatment(distant metastasis).The remaining 16 cases recovered well in regular reviews without complications such as abdominal pain,fever,or vaginal bleeding.Conclusions If the size and location of the cancer lesion do not affect the removal of IUD after radiotherapy for cervical cancer,it should be removed as soon as possible.The application of abdominal ultrasound guided hysteroscopy in IUD removal in patients with cervical cancer after radiotherapy is safe and feasible to a certain extent.

Objective:To explore the prevalence and independent associated factors of vascular calcification (VC) in non-dialysis chronic kidney disease (CKD) patients of stage 3-5.Methods:It was a single-center cross-sectional observational study. Non-dialysis stage 3-5 CKD patients ≥18 years old who were admitted to the Department of Nephrology, the First Affiliated Hospital of Sun Yat-sen University from May 1, 2022 to December 31, 2022 with VC evaluation were enrolled. The patients' general information, laboratory examination and imaging data were collected. Coronary artery calcification (CAC), thoracic aorta calcification (TAC), abdominal aorta calcification (AAC), carotid artery calcification and aortic valve calcification (AVC) were evaluated by cardiac-gated electron-beam CT (EBCT) scans, lateral lumbar x-ray, cervical macrovascular ultrasound and echocardiography, respectively. The differences in clinical data and the prevalence of VC at different sites of patients with different CKD stages were compared, and the prevalence of VC at different sites of patients in different age groups [youth group (18-44 years old), middle-aged group (45-64 years old) and elderly group (≥65 years old)] and patients with or without diabetes were compared. Multivariate logistic regression analysis was used to analyse the independent associated factors of VC for different areas.Results:A total of 206 patients aged (51±14) years were included, including 129 (62.6%) males. There were 44 patients with CKD stage 3 (21.4%), 51 patients with CKD stage 4 (24.8%), and 111 patients with CKD stage 5 (53.9%). CKD was caused by chronic glomerulonephritis [104 cases (50.5%)], diabetic kidney damage [35 cases (17.0%)], hypertensive kidney damage [29 cases (14.1%)] and others [38 cases (18.4%)]. Among 206 patients, 131 (63.6%) exhibited cardiovascular calcification, and the prevalence of CAC, TAC, AAC, carotid artery calcification, and AVC was 37.9%, 43.7%, 37.9%, 35.9% and 9.7%, respectively. The overall prevalence of VC in young, middle-aged and elderly patients was 24.6%, 73.6% and 97.4%, respectively. With the increase of age, the prevalence of VC in each site gradually increased, and the increasing trend was statistically significant (all P<0.001). The overall prevalence of VC in CKD patients with diabetes was 92.5% (62/67), and the prevalence of VC at each site in the patients with diabetes was significantly higher than that in the patients without diabetes (all P<0.001). Multivariate logistic regression analysis revealed that age (every 10 years increase, OR=2.51, 95% CI 1.77-3.56, P<0.001), hypertension ( OR=5.88, 95% CI 1.57-22.10, P=0.009), and diabetes ( OR=4.66, 95% CI 2.10-10.35, P<0.001) were independently correlated with CAC; Age (every 10 years increase, OR=6.43, 95% CI 3.64-11.36, P<0.001) and hypertension ( OR=6.09, 95% CI 1.33-27.84, P=0.020) were independently correlated with TAC; Female ( OR=0.23, 95% CI 0.07-0.72, P=0.011), age (every 10 years increase, OR=3.90, 95% CI 2.42-6.29, P<0.001), diabetes ( OR=5.37, 95% CI 2.19-13.19, P<0.001) and serum magnesium ( OR=0.01,95% CI 0-0.35, P=0.014) were independently correlated with AAC. Moreover, age and diabetes were independently correlated with carotid artery calcification, AVC and overall VC Conclusions:The prevalence of VC in non-dialysis CKD patients of stage 3-5 is 63.59%, of which CAC reaches 37.9%, TAC is the most common one (43.7%), while AVC is the least one (9.7%). Age and diabetes are the independent associated factors for VC of all sites except TAC, while hypertension is an independent associated factor for both CAC and TAC.
