OBJECTIVE To investigate ameliorative effects and mechanisms of two probiotics （Bacillus subtilis， Lactobacillus acidophilus） combined with Aurantii Fructus Immaturus （AFI） on functional dyspepsia （FD） in rats. METHODS Rats were randomly divided into blank group， model group， positive control group （domperidone group， 2.7 mg/kg）， AFI group （9 g/kg）， L. acidophilus group （5×107 cfu/kg）， B. subtilis group （5×107 cfu/kg）， L. acidophilus+ AFI group （L. acidophilus 5×107 cfu/kg+ AFI 9 g/kg）， and B. subtilis+AFI group （B. subtilis 5×107 cfu/kg+AFI 9 g/kg）， with 8 rats in each group. Except for the blank group， FD model was established by tail-clamping stimulation+hunger and satiety disorder+swimming exhaustion in other groups. After modeling， each group was given the corresponding drug/probiotic suspensions/physiological saline intragastrically， once a day， for 14 consecutive days. After the last medication， gastric emptying rate and the rate of propulsion of the small intestine in rats were measured； the levels of brain-gut peptide-related indicators [gastrin （GAS）， substance P （SP）， vasoactive intestinal peptide （VIP）， somatostatin （SS） and cholecystokinin （CCK）] in the serum of rats were measured. The pathological morphology of the gastric antrum tissue and duodenal tissue was observed. Cecal contents from the rats were collected for gut microbiota sequencing analysis. The protein expression levels of tyrosine kinase receptor c-Kit and stem cell factor （SCF） in the gastric antrum tissue， as well as Toll-like receptor 4 （TLR4）， myeloid differentiation factor 88 （MyD88）， and nuclear factor κB （NF-κB） in the duodenal tissue of the rats were detected. RESULTS Compared with the blank group， model group showed significantly lower gastric emptying rate， small intestinal propulsion rate， serum levels of GAS and SP， relative abundance of Firmicutes， Ace， Chao and Sobs indexes of the gut microbiota， and protein levels of SCF and c-Kit in gastric antrum （P＜0.05）， while serum levels of VIP， SS and CCK， relative abundance of Bacteroidetes， as well as protein expressions of TLR4， MyD88， and NF-κB， were significantly higher （P＜0.05）. The histological structure JZYC23S53） of the gastric antrum tissue appeared basically normal； however， abnormalities were observed in the duodenal structure， with a significant infiltration of inflammatory cells visible. Compared with the model group， all treatment groups significantly modulated most of the above indexes （P＜0.05）. The histological structure of the gastric antrum tissue was normal. Except for the B. subtilis group and the B. subtilis+AFI group， the pathological states of the duodenum in the remaining rats gradually recovered. Compared with each single drug group， most of above indexes in rats from each combination group showed further improvement （P＜0.05）. CONCLUSIONS The combination of AFI with two probiotics can improve gastrointestinal motility in FD rats， and the effect is superior to that of using the drugs alone. The specific underlying mechanisms may be related to the activation of the SCF/c-Kit signaling pathway and the inhibition of the TLR4/MyD88/NF-κB signaling pathway.

AIM: To explore the therapeutic effect of oral Xuefu Zhuyu Pill combined with intravitreal injection of aflibercept in the treatment of retinal vein occlusion(RVO).METHODS: A total of 80 patients(80 eyes)with RVO admitted to our hospital from January 2021 to March 2024 were prospectively selected. According to the treatment method, they were divided into a control group of 40 patients treated with intravitreal injection of aflibercept, and an observation group of 40 patients treated with oral Xuefu Zhuyu Pill combined with intravitreal injection of aflibercept. The efficacy, TCM syndrome score, retinal microcirculation parameters, macular edema(ME), and adverse reactions were compared between the two groups of patients in the treatment of RVO.RESULTS: All patients have completed follow-up. The clinical effective rate of the observation group after treatment was 95%, obviously higher than that of the control group(80%; χ2=4.114, P=0.043). After treatment for 3 mo, the traditional Chinese medicine syndrome scores, foveal avascular area(FAZ)area, FAZ circumference, macular central retinal thickness, and neovascularization leakage area of both groups decreased, the overall blood flow density of the superficial capillary plexus(SCP)and deep capillary plexuses(DCP)increased, and the observation group showed better results than the control group(all P<0.05). There was no statistically significant difference in the occurrence of adverse reactions between the two groups during the treatment period(P>0.05).CONCLUSION: Oral administration of Xuefu Zhuyu Pill combined with intravitreal injection of aflibercept in the treatment of RVO can improve retinal microcirculation, enhance vision, restore ocular blood circulation, improve bleeding, promote ME absorption, and improve clinical efficacy.

Objective To investigate the correlation between baseline data,early treatment response and prognosis in children with acute lymphoblastic leukemia(ALL).Methods Ninety-two children with ALL were divided into the endpoint event group(19 cases)and the event-free survival group(73 cases)according to whether there was an endpoint event(recurrence or death).The age and gender at initial diagnosis were recorded.Initial white blood cell count(WBC),platelet count(PLT),immunophenotype,chromosome karyotype,fusion gene,prednisone test,bone marrow remission status on the 15th day of induction chemotherapy and minimal residual disease(MRD)on the 15th,33rd and 55th day of induction chemotherapy were detected.The correlation between the above baseline data and early treatment response and the occurrence of endpoint event in children with ALL was analyzed.Logistic regression was used to analyze influencing factors of endpoint events in children with ALL.Receiver operating characteristic(ROC)curve was plotted to evaluate the predictive value of baseline data and early treatment response to endpoint events in children with ALL.Results The proportion of WBC≥100×109/L at first diagnosis,prednisone poor reaction and positive MRD on the 33rd day of induction chemotherapy were higher in the endpoint event group than those in the event-free survival group(P<0.05),and there were no significance differences in remaining indicators(P>0.05).Logistic regression analysis showed that prednisone poor reaction and positive MRD on the 33rd day of induction chemotherapy were risk factors for endpoint event in children with ALL(P<0.05),and the combined value of the two indicators was better than that of a single indicator in predicting endpoint events in children with ALL.Conclusion Prednisone poor reaction and positive MRD on the 33rd day of induction chemotherapy are associated with recurrence and death in children with ALL.

Objective:To explore and analyze the relationship between serum KLK11 and MK levels and the effect of first iodine 131 ( 131I) ablation after operation for differentiated thyroid cancer. Method:108 patients with differentiated thyroid cancer who underwent total thyroidectomy in our hospital from Jun. 2020 to Jun. 2021 were consecutively selected, and received radioactive ablation after surgery. There were 37 males and 71 females. The age was (48.32±4.25) years, ranging from 28 to 79 years. The patients were divided into successful ablation according to whether the ablation was successful after treatment. There were 64 cases in the group and 44 cases in the unsuccessful group, and 60 healthy people with no abnormality in physical examination during the same period were selected as the control group. The patients were divided into a metastasis-positive group of 20 cases and a metastasis-negative group of 88 cases according to whether lymph nodes occurred. After surgery, serum samples of all subjects were taken, and enzyme-linked immunosorbent assay was used to detect the levels of serum kallikrein-related peptidases 11 (KLK11) and midkine (MK) , and the levels of serum KLK11 and MK were analyzed. Gender, age, BMI, TNM stage, TSH, maximum diameter of lesion, and duration of nail removal were collected. Univariate analysis and logistic regression analysis were used to analyze the independent risk factors of postoperative efficacy.Result:The levels of serum KLK11 and MK in the successful and unsuccessful groups were higher than those in the control group, while the levels of KLK11 and MK in the unsuccessful group were higher than those in the successful group (KLK11: t= 2.642, P<0.05; MK: t=11.906, P<0.05) . The serum levels of KLK11 and MK in the metastasis-positive group were higher than those in the metastasis-negative group (KLK11: t= 2.908, P<0.05; MK: t=14.907, P<0.05) . Univariate analysis showed that BMI ( χ2=6.780, P=0.009) , maximum diameter of lesions ( χ2=14.819, P=0.001) , TSH ( χ2=13.627, P=0.001) , serum KLK11 ( t=2.642, P=0.01) , and serum MK ( t=11.906, P<0.001) were associated with the effect of first 131I ablation after surgery for differentiated thyroid cancer ( P<0.05) . Taking the success of ablation as the dependent variable, a multivariate logistic regression analysis was performed. The results showed that the maximum diameter of the lesions greater than 2 cm ( OR=10.740, 95%CI: 7.033-16.401) , increased level of TSH ( OR=8.559, 95%CI: 2.812-26.057) , increased serum KLK11 level ( OR=16.710, 95%CI: .548-32.666) and increased serum MK level ( OR=10.580, 95%CI: 6.294-17.786) were the factors affecting the first 131I ablation effect after DTC surgery ( P<0.05) . Conclusion:The elevated levels of serum KLK11 and MK are independent risk factors affecting the efficacy of the first 131I ablation after surgery for differentiated thyroid cancer.

Objective:To investigate the effects of micro video combined with situational experience health education program in elderly diabetic patients.Methods:Totally, 100 elderly diabetic patients were enrolled from January to December in 2018 in Sir Run Run Shaw Hospital Affiliated to Zhejiang University School of Medicine. They were assigned to experimental group ( n=50) and control group( n=50) by random number table. The control group received routine health education, while the experimental group received micro video combined with situational experience health education program. The intervention effects were assessed by Chinese version of Tilburg Frailty Indicator and Summary of Diabetes Self Care Action. Results:Finally, 45 cases were included in the experimental group and 47 cases in the control group. There was no significant difference between the two groups before intervention ( P>0.05). After intervention, the scores of physical frailty, psychological frailty, social frailty and total frailty were (2.60 ± 1.19) points, (1.24 ± 0.87) points, (1.11 ± 0.83) points and (4.96 ± 1.76) points in the experimental group, significantly lower than in the control group (3.45 ± 1.18) points, (1.96 ± 0.86) points, (2.06 ± 0.79) points and (7.47 ± 1.57) points. The difference was statistically significant ( t values were 3.32-7.23, P<0.01); the scores of diet, exercise, blood glucose monitoring, medication, foot care dimension and total self-care activities were (20.36 ± 2.22) points, (12.02 ± 2.33) points, (5.07 ± 0.81) points, (9.98 ± 1.99) points, (7.53 ± 1.10) points and (54.96 ± 4.49) points in the experimental group, significantly higher than in the control group (18.96 ± 2.12) points, (10.47 ± 2.24) points, (3.85 ± 0.83) points, (8.62 ± 1.69) points, (6.60 ± 1.12) points and (48.49 ± 4.07) points. the difference was statistically significant ( t values were 3.10-7.25, P<0.01). Conclusions:Micro video combined with situational experience can improve frailty status and self-care activities in elderly patients with diabetes.

Objective:To investigate the influencing factors for lymph node metastasis and prognosis in stage T1 and T2 esophageal squamous cell carcinoma after radical surgery and construct nomogram prediction models.Methods:The retrospective cohort study was conducted. The clinico-pathological data of 672 patients with T1 and T2 esophageal squamous cell carcinoma who were admitted to the Affiliated Hospital of North Sichuan Medical College from January 2014 to December 2019 were collected. There were 464 males and 208 females, aged (65±8)years. All patients under-went radical esophagectomy+2 or 3 field lymph node dissection. Observation indicators: (1) lymph node dissection, metastasis and follow-up. (2) risk factors for lymph node metastasis of esophageal cancer after radical resection. (3) prognostic factors of esophageal cancer after radical resection. (4) construction and evaluation of the prediction models of lymph node metastasis and prognosis of esophageal cancer after radical resection. Follow-up was conducted using outpatient examination, telephone and internet consultations to detect survival of patients up to April 2021. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Kaplan-Meier method was used to calculate survival rate and draw survival curve. Log-Rank test was used for survival analysis. Logistic regression model was used for univariate and multivariate analyses of risk for lymph node metastasis, and COX regression model was used for univariate and multivariate analyses of prognosis. Based on the results of multi-variate analysis, the nomogram prediction models for lymph node metastasis and prognosis predic-tion were constructed. The prediction discrimination of the nomogram models were evaluated using the area under curve (AUC) of the receiver operating characteristic curve (ROC). The calibration curve was used to evaluate the prediction consistency of the models. Results:(1) Lymph node dissection, metastasis and follow-up. The number of lymph node dissected was 14±8 and the number of lymph node metastasis was 2(range, 1?19) in 672 patients. Of the 672 patients, there were 182 cases had lymph node metastasis, including 58 cases in T1 stage and 124 cases in T2 stage. All 672 patients were followed up for 38 (range, 1?85)months. The average overall survival time of 672 patients was 65 months, with the 1-, 3-, 5-year overall survival rate as 89.0%, 74.3%, 66.0%, respectively. The average overall survival time of 325 patients in T1 stage and 347 patients in T2 stage were 70 months and 61 months. The 1-, 3-, 5-year overall survival rate of 325 patients in T1 stage and 347 patients in T2 stage were 95.0%, 83.5%, 73.4% and 87.4%, 69.9%, 59.2%, respectively, showing a significant difference in survival between them ( χ2=14.51, P<0.05). (2) Risk factors for lymph node metastasis of esophageal cancer after radical resection. Results of univariate analysis showed that tumor location, tumor histological grade, tumor T staging were related factors affecting lymph node metastasis of esophageal cancer after radical resection ( odds ratio=1.40, 1.54, 2.56, 95% confidence interval as 1.07?1.85, 1.20?1.99, 1.79-3.67, P<0.05). Results of multivariate analysis showed that tumor location, tumor histological grade, tumor T staging were independent factors affecting lymph node metastasis ( odds ratio=1.42, 1.61, 2.63, 95% confidence interval as 1.07?1.89, 1.25?2.09, 1.82?3.78, P<0.05). (3) Prognostic factors of esophageal cancer after radical resection. Results of univariate analysis showed that preoperative comorbidities, postoperative complications, tumor histological grade (G3), tumor T staging, tumor N staging (N1 stage, N2 stage, N3 stage), tumor TNM staging (Ⅲ stage, Ⅳ stage) were related factors affecting prognosis of esophageal cancer after radical resection ( hazard ratio= 1.48, 1.64, 2.23, 1.85, 2.09, 4.48, 4.97, 3.54, 5.53, 95% confidence interval as 1.08?2.03, 1.20?2.23, 1.47?3.39, 1.34?2.54, 1.44?3.04, 2.89?6.95, 1.57?15.73, 2.48?5.05, 1.73?17.68, P<0.05). Results of multivariate analysis showed that preoperative comorbidities, G3 of tumor histological grade, T2 stage of tumor T staging, N1 stage, N2 stage, N3 stage of tumor N staging were independent risk factors affecting prognosis of esophageal cancer after radical resection ( hazard ratio=1.57, 1.89, 1.63, 1.71, 3.72, 3.90, 95% confidence interval as 1.14?2.16, 1.23?2.91, 1.17?2.26, 1.16?2.51, 2.37?5.83, 1.22?12.45, P<0.05). (4) Construction and evaluation of the prediction models of lymph node metastasis and prognosis of esophageal cancer after radical resection. Based on the results of multivariate analysis, tumor location, tumor histological grade, tumor T staging were applied to construct a nomo-gram model for lymph node metastasis prediction of esophageal cancer after radical resection, the score of tumor location, tumor histological grade, tumor T staging were 82, 100, 100, respectively, and the sum of the scores corresponding to the lymph node metastasis rate. Preoperative comor-bidity, tumor histological grade, tumor T staging, tumor N staging were applied to construct a nomo-gram model for 1-, 3-, 5-year overall survival rate prediction of esophageal cancer after radical resection, the score of preoperative comorbidity, tumor histological grade, tumor T staging, tumor N staging were 23, 38, 27, 100, respectively, and the sum of the scores corres-ponding to the 1-, 3-, 5-year overall survival rate. Results of ROC showed that the AUC of nomogram model for lymph node metastasis prediction after radical esophagectomy was 0.66 (95% confidence interval as 0.62?0.71, P<0.05). The AUC of nomogram model for 1-, 3-, 5-year overall survival rate prediction after radical esophagectomy were 0.73, 0.74, 0.71 (95% confidence intervals as 0.66?0.80, 0.68?0.79, 0.65?0.78, P<0.05). Results of calibration curve showed that the predicted lymph node metastasis rate and the predicted 1-, 3-, 5-year overall survival rate by nomogram models were consistent with the actual lymph node metastasis rate and 1-, 3-, 5-year overall survival rate. Conclusions:Tumor location, tumor histological grade, tumor T staging are independent factors affecting lymph node metastasis in T1 and T2 esophageal squamous cell carcinoma after radical surgery and nomogram model constructed by these indicators can predict the lymph node metas-tasis rate. Preoperative comor-bidities, G3 of tumor histological grade, T2 stage of tumor T staging, N1 stage, N2 stage, N3 stage of tumor N staging are independent risk factors affecting prognosis and nomogram model constructed by these indicators can predict the overall survival rate of patients after surgery.

Objective:To analyze the causes and influencing factors of conversion from laparoscopic surgery to laparotomy.Methods:To analyze and summarize the clinical data of 84 patients who converted to laparotomy in 16 203 cases of laparoscopic surgery from August 2017 to August 2020 in the Department of Gynecology of the Affiliated Hospital of Qingdao University, each patient converted to surgery was matched with 2 patients who underwent simple laparoscopic surgery. The patients were divided into conversion to laparotomy group (84 cases) and control group (168) cases, and analyze the influencing factors of laparoscopic conversion to laparotomy. χ 2 test or corrected χ 2 test or Fisher exact probability method were used for the comparison of counting data between groups, and conditional regression analysis was used for the multivariate analysis of case control design. Results:The conversion rate of gynecologic laparoscopic surgery to laparotomy was 0.52%(84/16 203). The reasons for 84 cases of conversion from laparoscopic surgery to open surgery were as follows: pelvic adhesion 50.0%(42/84), unexpected malignant tumor 19.0%(16/84), tumor oversize or special shape and location 14.3%(12/84), hemostasis difficulty 7.1%(6/84), multiple uterine fibroids 3.5%(3/84), simultaneous surgery 3.5%(3/84), bladder injury 1.2%(1/84), and subcutaneous emphysema 1.2%(1/84) during the operation. There were no significant differences in body mass index and comorbidities (diabetes, hypertension, coronary heart disease, thyroid disease) between the two groups (all P>0.05). And the history of endometriosis was 36.9% (31/84) and the history of pelvic surgery in the transperitoneal group was 60.7% (51/84) higher than that in the conversion to laparotomy group of 20.8% (35/84), 30.6% (51/84) (χ 2=7.482, 21.42, P=0.006). The results of conditional regression analysis showed that that surgical history( OR=3.979, 95% CI 2.010-7.874, P<0.001 and thyroid history ( OR=15.333, 95% CI 1.087-216.346, P=0.005) increased the risk of conversion to laparotomy; Hypertension history ( OR=0.203, 95% CI 0.067-0.622, P=0.005) reduced the risk of conversion to laparotomy. Further analysis of which operation type affected the conversion to laparotomy showed that cesarean section ( OR=2.105, 95% CI 1.109-4.351, P=0.044), myomectomy ( OR=11.605, 95% CI 3.306-40.735, P<0.001), and ovarian cyst removal ( OR=7.914, 95% CI 2.157-21.037, P=0.002) affected the conversion to laparotomy. Conclusion:The main reason for conversion from gynecologic laparoscopic surgery to laparotomy is pelvic adhesion. The history of surgery and thyroid disease are the risk factors for conversion to laparotomy. Among them, myomectomy and ovarian cyst removal are important factors for conversion to laparotomy. Before operation, appropriate clinical operation methods should be selected according to the patient's medical history and condition to ensure the patient's safety.

Objective:To analyze immune effects of children with different immunization schedules after the conversion of polio vaccine immunization strategy.Methods:Serum samples of children with different immunization schedules were collected in 2018 and 2021 respectively. The neutralizing antibody against poliovirus was detected by micro cell neutralization test, and the antibody positive rate and geometric mean titer (GMT) were analyzed.Results:The positive rates of neutralizing antibodies against type I and type III poliovirus in children immunized with two doses inactivated polio vaccine (IPV) and two doses bivalent live attenuated oral polio vaccine (bOPV), one dose IPV and 3 doses bOPV were both 100.00%. The GMT for type I poliovirus antibody were higher than 1∶300, and for type III poliovirus antibody were close to 1∶200. In children vaccinated with IPV, the positive rates of type I and III poliovirus antibodies were 96.72% and 95.08%, and the GMT for type I and III poliovirus antibodies were 1∶96.72 and 1∶48.72, respectively. In children vaccinated with trivalent live attenuated oral polio vaccine (tOPV) only, the positive rates of type I and III poliovirus antibodies were 98.68% and 96.05%, and the GMT for type I and III poliovirus antibodies were 1∶126.84 and 1∶68.22, respectively. In children vaccinated with three doses tOPV and one dose bOPV, the positive rates of type I and III poliovirus antibodies were 100.00% and 98.57%, and the GMT for type I and III poliovirus antibodies were 1∶214.21 and 1∶94.17, respectively.Conclusions:Children who received sequential immunization with IPV and live attenuated oral polio vaccine (OPV) have a high level of positive rate and GMT of neutralizing antibody against poliovirus type I and III.
