ObjectiveTo investigate the relationship between the non-fasting triglyceride and glucose （TyG） index and hyperglycemia in pregnancy during the third trimester in high altitudes. MethodsThis study selected clinical and laboratory data of 774 Tibetan singleton pregnant women who delivered at Chaya People's Hospital of Qamdo city in Xizang autonomous region， from January 2023 to April 2025. The non-fasting TyG index was calculated from non-fasting triglyceride （TG） and random plasma glucose （PG）. Based on the tertiles of the non-fasting TyG index values， the individuals were split into three groups （corresponding to non-fasting TyG index of 8.89 and 9.21， respectively）. The baseline clinical characteristics， lipid levels and the occurrence of developing hyperglycemia in pregnancy were compared among the three groups. Statistical analyses were performed using ANOVA， Kruskal-Wallis H test， Chi-square test， or Fisher exact test and the relationship between the non-fasting TyG index and hyperglycemia in pregnancy were examined using multivariate logistic regression models and curve fitting. ResultsA total of 774 Tibetan singleton pregnant women were included， with a average age of 27.3 ± 6.1 years， a pre-delivery body mass index （Pre-BMI） of （25.2±2.3）kg/m² ， a proportion of 26.7% （207/774） primigravid women， the mean non-fasting TyG index was 9.1 ± 0.4。Thirty pregnant women were diagnosed with hyperglycemia in pregnancy， with a detection rate of 3.9% （30/774）. Statistically significant differences in serum total cholesterol （TC）， TG， low-density lipoprotein cholesterol （LDL-C） and high-density lipoprotein cholesterol （HDL-C） levels were identified when comparing different non-fasting TyG groups （all P values <0.05）. Subsequent trend test analysis indicated that the levels of TC， TG， LDL-C， and PG gradually increased with elevated the non-fasting TyG index （ F_{trend TC}=95.61， P<0.001； F_{trend TG}=1 051.91， P<0.001； F_{trend LDL-C} = 97.20， P < 0.001； F_{trend TG}=195.20； P<0.001）. After adjustment for maternal age， pre-delivery BMI， altitude， TC， LDL-C， and HDL-C， multivariate Logistic regression models revealed independent positive associations between non-fasting TyG index and hyperglycemia in pregnancy （Model 1： OR=2.72， 95% CI： 1.13-6.53， P=0.026； Model 2： OR=2.56， 95% CI： 1.01-6.50， P=0.048； Model 3： OR=2.72， 95% CI： 1.06-6.97， P=0.037； Model 4： OR=4.02， 95% CI： 1.42-11.40， P=0.009） and the incident of hyperglycemia in pregnancy showed an increasing tendency as increasing with the non-fasting TyG index， however， this association did not statistical significance （P _trend >0.05）. Curve fitting by restricted cubic splines （RCS） were used to assess linearity between non-fasting TyG and hyperglycemia in pregnancy， and there was a linear dose-response relationship between non-fasting TyG and hyperglycemia in pregnancy （P _{for non-linear} = 0.515）. ConclusionNon-fasting TyG index in the third trimester is a risk factor for hyperglycemia in pregnancy among the Tibetan singleton pregnant women at high altitudes and there was a possible linear dose-response relationship between the non-fasting TyG index and hyperglycemia in pregnancy.

Objective To investigate the effect of Anlotinib on proliferation and apoptosis in non-small cell lung cancer(NSCLC)cells and its molecular mechanism.Methods Non-small cell lung cancer cell lines A549 and H1299 were incubated with Anlotinib,miR-16-5p agonist and/or PD-1 overexpression vector respectively.CCK-8 assay and EDU assay were applied to detect the proliferation.Flow cytometry was performed to detect the cell apop-tosis.The relative expression of miR-16-5 p in A549 and H1299 was detected by real-time quantitative polymerase chain reaction(RT-qPCR).The relative protein expression of PD-1 in A549 and H1299 was detected by Western blot assay.The interaction between miR-16-5p and PD-1 was determined by dual luciferase reporter assay.Finally,A549 cell xenograft model was established to assess the effect of Anlotinib on tumor growth in vivo.Results Anlotinib significantly increased miR-16-5p expression and decreased PD-1 expression in A549 cells and H1299 cells,inhibited cell proliferation and promoted apoptosis in a dose-dependent manner(P＜0.05).The highly-expressed miR-16-5p inhibited proliferation and promoted cell apoptosis(P＜0.05).Also,miR-16-5p targeted at PD-1 and negatively regulated PD-1 expression.Knockdown of PD-1 inhibited proliferation and pro-moted cell apoptosis(P＜0.05).PD-1 over-expression reversed the Anlotinib-mediated pro-proliferation and anti-apoptosis of miR-16-5p in A549 cells and H1299 cells(P＜0.05).Anlotinib significantly reduced tumor growth in vivo(P＜0.05).Conclusions Anlotinib may inhibit cell proliferation,anti-apoptosis,and reduce tumor growth for NSCLC,which is involved in miR-16-5p/PD-1 axis.

Objective To evalute the drug resistance characteristics of tuberculosis(TB)patients of all ages in Guangdong Province during 2014-2020,and provide prevention and treatment strategies of tuberculosis.Method We used 39,048 clinical isolates of Mycobacterium tuberculosis(MTB)belonging to patients with confirmed TB from 2014 to 2020,from 32 TB drug-resistant surveillance sites in Guangdong Province,and we retrospectively analyzed the laboratories data of patients with drug-resistant TB,and grouped patients by age and region,to explore the trend of drug-resistance of MTB clinical isolates,the trend and incidence differences of multi-resistant TB(including monodrug-resistant TB(MR-TB),polydrug-resistant TB(PDR-TB),multidrug-resistant TB(MDR-TB)and exten-sively drug-resistant TB(XDR-TB)),and resistance characteristics of MTB clinical isolates to drugs in focus(rifam-picin and ofloxacin).Result The differences in the resistance rates of MTB clinical isolates to nine antituberculosis drugs among patients at 32 TB drug resistance surveillance sites in Guangdong Province from 2014 to 2020 were not statistically significant(P>0.05).The rates of MR-TB,PDR-TB,MDR-TB,XDR-TB,and total resistance isolates of MTB clinical isolates were 14.46%,5.16%,5.16%,4.58%,and 1.29%,respectively.he pediatric group had a higher MR rate(15.4%)than the adult and geriatric groups,while the adult and geriatric groups had higher MDR rates(5.0%and 5.0%,respectively).The geriatric group also had a higher XDR rate(2.1%),with statistically significant differences(P<0.001).The rates of MR-TB(14.8%),PDR-TB(5.3%),MDR-TB(4.7%),XDR-TB(1.4%),ofloxacin resistance(11.33%)and rifampicin resistance(6.92%)of MTB clinical isolates were higher in patients from the Pearl River Delta than in other regions of Guangdong Province,with statistically significant differ-ences(P<0.001).Conclusion According to the data from the surveillance sites,the epidemiological trend of drug-resistant TB in Guangdong Province is leveling off during the period 2014-2020.However,the incidence of drug-resistant TB is higher in specific populations(e.g.children and the elderly),and the incidence of drug-resistant TB and the rate of drug resistance to drugs in focus are higher in the Pearl River Delta than in other regions of Guang-dong Province,necessitating further investigation and the development of novel prevention and control strategies.

The application of function-preserving pancreatic surgery as a restrictive resection technique is primarily targeted towards benign or those with borderline or low-grade lesions. This approach has been shown to significantly improve both short-term and long-term quality of life outcomes for patients following surgical intervention. In comparison to conventional laparoscopic procedures, robotic surgical systems have demonstrated superior efficacy and precision when employed in pancreas surgeries, and the safety and reliability are widely recognized within the medical community. Nevertheless, there remains a dearth of research investigating the specific appli-cations of robotic-assisted function-preserving pancreatic surgery. Consequently, the authors compre-hensive review the latest progress on robot-assisted function-preserving pancreatic surgery, while highlighting of surgical scope, techniques utilized during these procedures as well as associated prognostic considerations.

Objective To evaluate the efficacy and safety of budesonide combined with pulmonary surfactant(PS)in the treatment of meconium aspiration syndrome(MAS)in neonates.Methods PubMed,Cochrane Central Register of Controlled Trials(Central),Embase,Web of Science,SinoMed,VIP,WanFang Data and CNKI databases were electronically searched to collect randomized controlled trials(RCTs)of budesonide combined with PS in the treatment of neonatal MAS from inception to September 2,2023.Two researchers independently screened literature,extracted data and assessed the risk of bias of the included studies,meta-analyses were performed by using the RevMan 5.4 software.Results A total of 6 RCTs involving 544 patients were included.The results of meta-analysis showed that compared with PS group,budesonide combined with PS group had higher overall effective rate(RR=1.29,95％CI 1.17 to 1.41,P＜0.001),shorter hospital stay(MD=-6.35,95％CI-9.25 to-3.46,P＜0.001)and shorter time of oxygen inhalation(MD=-1.61,95％CI-2.23 to-0.98,P＜0.001),shorter the duration of ventilator use(MD=-26.46,95％CI-35.98 to-16.95,P＜0.001),improved the blood gas analysis indexes at each time after treatment(P＜0.05);In terms of safety,the incidence of total complications and adverse reactions in budesonide combined with PS group was significantly lower(RR=0.35,95％CI 0.25 to 0.47,P＜0.001).Subgroup analysis showed that the incidence of persistent pulmonary hypertension of the newborn(PPHN)in the budesonide combined with PS group was decreased(RR=0.38,95％CI 0.19 to 0.74,P=0.004),and the incidence of pneumorrhagia was decreased(RR=0.26,95％CI 0.10 to 0.69,P=0.007),and the difference was statistically significant;the incidence of heart failure and sepsis was not statistically significant compared with the PS group(P＞0.05).Conclusion Current evidence shows that budesonide combined with PS in the treatment of neonatal meconium aspiration syndrome can improve the symptoms and signs of MAS children,improve the blood gas analysis index,accelerate disease rehabilitation,shorten the course of the disease,can help reduce the risk of complications and PPHN,pneumorrhagia,and doesn't increase the incidence of heart failure,sepsis.Due to the limited quantity of the included studies,more high-quality and large-sample RCTs are needed to further validate the above conclusions.

OBJECTIVE To identify the chemical constituents of Rhamni Songoricae Fructus and to establish their fingerprints and the method for simultaneous determination of four constituents to comprehensively evaluate the quality of Rhamni Songoricae Fructus. METHODS The chemical constituents in Rhamni Songoricae Fructus were qualitatively analyzed by ultra-performance liquid chromatography quadrupole-time-of-flight tandem mass spectrometry. The fingerprints of 15 batches of Rhamni Songoricae Fructus were established by HPLC and chemometric analysis was performed by using SPSS 26.0 and SIMCA 14.1 software； the contents of quercetin， kaempferol， kaempferide and emodin were determined by the same method. RESULTS A total of 35 constituents were identified， including 28 kinds of flavonoids， 5 kinds of anthraquinones and 2 kinds of organic acids. A total of 19 common peaks were identified in the HPLC fingerprints， recognizing quercetin， kaempferol， kaempferide and emodin. The similarities between HPLC fingerprints of 15 batches of samples and control chromatograms were greater than 0.9. The results of cluster analysis showed that 15 batches of samples were divided into 2 classes， of which S1-S5， S7 and S9 were one class and the rest were one class， similar to the results of principal component analysis. The results of the orthogonal partial least squares- discriminant analysis showed that the variable importance projections of peaks No. 2， 6， 1， 11 （quercetin）， 3， 14， 8， 10， 19 （emodin）， 5 were all greater than 1. The contents of quercetin， kaempferol， kaempferide and emodin ranged from 0.710 to 10.478 mg/g， 0.236 to 0.660 mg/g， 0.334 to 3.039 mg/g， and 0.261 to 0.504 mg/g. CONCLUSIONS The constructed chemical constituent identification， fingerprint and content determination methods are simple， feasible and reproducible， which combined with chemometric analysis can be used for comprehensive evaluation of the quality of Rhamni Songoricae Fructus.

Objective To analyze the spatial relationship between the roots of maxillary anterior premolars and the maxillary sinus,thus providing an anatomical basis for timing,planning,surgical approaches,and implant selection at this site.Methods Cone beam CT(CBCT)images were collected from 264 patients(aged 20-65 years)who visited the Ruihua Dental Clinic between January 2017 and March 2023.The minimum distance from the apex of the maxillary an-terior premolar roots to the lower wall of the maxillary sinus was measured on the coronal plane.The classification of the vertical relationship between the tooth root and the lower wall of the maxillary sinus was performed,and comparisons were made bilaterally,between genders,and among different age groups.Results The minimum distance(Q50)from the apex of the first maxillary premolar root to the lower wall of the maxillary sinus was 7.34 mm for the single-root type,7.80 mm for the buccal root of the double-root type,and 7.36 mm for the palatal root.For the second maxillary premo-lar,the median distance was 2.56 mm for the single root type,1.73 mm for the buccal root type,and 1.23 mm for the palatal root type.There was a significant difference in the shortest distance from the apex of the right second maxillary premolar single root to the lower wall of the maxillary sinus among the different age groups(P＜0.05),with the 20-29-year-old group having the smallest median distance(1.52 mm)and the≥40-year-old group having the largest(4.44 mm).There was no significant difference in the effect of sex or laterality on distance(P＞0.05).The most common vertical relationship between the apex of the maxillary anterior premolar roots and the lower wall of the maxillary sinus was non-contact.There was no significant difference in the vertical relationship classification between the single-root and dou-ble-root types(P＞0.05).Conclusion Most maxillary first premolar roots can provide sufficient bone height,which makes it easy to achieve immediate implantation.The maxillary second premolar root frequently involves insufficient bone,which is necessary to make full use of the bone wall of the extraction socket or the sinus floor cortical bone to achieve initial stability.The vertical relationship between the premolar root and maxillary sinus was influenced by age and dental position.Younger age groups often exhibit inadequate bone height,and the indication for immediate implan-tation should be carefully considered.The number of roots does not significantly affect the relationship between the sinus and root;however,double-rooted premolars offer more support for immediate implantation and socket healing due to the small root diameter and bony separation between the roots.

Objective To investigate the role of cardiac rehabilitation program in the early recovery after minimally invasive incision coronary artery bypass grafting with general anesthesia. Methods A retrospective study was performed on the patients who underwent minimally invasive incision coronary artery bypass grafting from January 2015 to January 2020 with general anesthesia in our hospital. The patients were divided into a cardiac rehabilitation group and a control group. The clinical data of the patients were collected in 6 months and 12 months after the beginning of cardiac rehabilitation program and were analyzed by propensity score-matching analysis with a ratio of 1∶1. The main outcomes were the peak oxygen uptake (VO2 peak) of cardiopulmonary function test and the number of patients attending cardiovascular specialties in tertiary hospitals during the follow-up period (20 months). Results A total of 600 patients were enrolled, including 200 patients in the cardiac rehabilitation group [137 males and 63 females, aged 61.00 (56.00, 65.00) years] and 400 patients in the control group [285 males and 115 females, aged 60.00 (56.00, 65.00) years]. After matching, 176 patients were included in each group, and the basical clinical data of the pateints were comparable (P>0.05). The VO2 peak of the cardiac rehabilitation group after 6 months and 12 months of cardiac rehabilitation was significantly different from that of the control group [6 months: 1.96 (1.59, 2.38) L/min vs. 1.72 (1.38, 2.12) L/min, P<0.001; 12 months: 2.40 (2.21, 2.63) L/min vs. 2.12 (1.83, 2.45) L/min, P<0.001]. During the follow-up period, there was a statistical difference in the cardiovascular specialist visits in tertiary hospitals (P=0.004). Conclusion Cardiac rehabilitation program has a positive effect on the recovery of minimally invasive incision coronary artery bypass grafting with general anesthesia, and can improve the exercise ability of patients.

OBJECTIVE To establish the project approval evaluation system for traditional Chinese medicine （TCM） preparations in medical institutions guided by new drug conversion， to improve the success rate of approval for TCM preparations in medical institutions and lay the foundation for the later drug conversion. METHODS Research and development team used the literature research method and brainstorming method to list and organize relevant elements of project evaluation and determine the initial indicator system. Experts were consulted using the Delphi method to confirm the evaluation index. The weights were calculated based on the proportion of importance scores for each indicator and assigned specific scores to each item. The indicator system was used to evaluate 31 TCM preparations applied for filing by various departments of our hospital from April to July 2023. RESULTS After two rounds of 17 experts’ consultation， the final TCM preparation system included five primary indicators， i.e. theoretical basis， clinical research foundation， pharmaceutical foundation， prescription， and clinical value， as well as 17 secondary indicators including prescription source， traditional Chinese medicine theory， clinical positioning and so on. Human experience was considered as the item which would be rejected as one vote. Based on the above indicator system， our hospital further improved the filing and project approval process for TCM preparations in medical institutions. Among the 31 TCM preparations applied for filing by various departments from April to July 2023， 8 TCM preparations with a score ≥65 were selected for development. CONCLUSIONS The evaluation system is objective， comprehensive， and highly operable. It is suitable for the selection of TCM preparations in medical institutions before research and development.

Objective To investigate the effect of blood flow restriction combined with low-intensity plyometric jump training(LI-PJT+BFR)on lower limb dynamic postural control of functional ankle instability(FAI)in college students. Methods From March to May,2023,40 FAI college students were recruited from Xi'an Physical Education University,and randomly divided into high-intensity plyometric jump training(HI-PJT,n = 14)group,low-intensity plyomet-ric jump training(LI-PJT,n = 13)group and LI-PJT+BFR group(n = 13).All the groups finished the six-week corresponding training.The maximum voluntary isometric contraction(MVIC)of tibialis anterior,peroneus lon-gus,lateral head of gastrocnemius,gluteus maximus,vastus lateralis,biceps femoris and semitendinosus were measured,and the root mean square(RMS)of electromyography of these muscles was measured during the sin-gle-leg landing(SLL),using wireless surface electromyography before and after intervention.Moreover,they were assessed with Y-balance test and Cumberland Ankle Instability Tool(CAIT). Results MVIC and RMS of the target muscles improved after intervention in all the groups(t>2.218,P<0.05),except MVIC and RMS of peroneus longus,gluteus maximus,biceps femoris and semitendinosus in LI-PJT group,and RMS of peroneus longus in LI-PJT+BFR group;and MVIC and RMS of the target muscles were the least in LI-PJT group(F>3.262,P<0.05),except those of peroneus longus.The extension scores of Y-balance test and the total score improved after intervention(t>2.485,P<0.05),and they were the least in LI-PJT group(F>5.042,P<0.05).The CAIT score improved after intervention(t>5.227,P<0.001),and it was the least in LI-PJT group(F = 4.640,P<0.05). Conclusion LI-PJT+BFR could improve lower limb dynamic postural control of FAI college students,which is similar to HI-PJT.
