Prescription optimization is a crucial aspect in the study of traditional Chinese medicine （TCM） compounds. In recent years， the introduction of mathematical methods， data mining techniques， and artificial neural networks has provided new tools for elucidating the compatibility rules of TCM compounds. The study of TCM compounds involves numerous variables， including the proportions of different herbs， the specific extraction parts of each ingredient， and the interactions among multiple components. These factors together create a complex nonlinear dose-effect relationship. In this context， it is essential to identify methods that suit the characteristics of TCM compounds and can leverage their advantages for effective application in new drug development. This paper provided a comprehensive review of the cutting-edge optimization experimental design methods applied in recent studies of TCM compound compatibilities. The key technical issues， such as the optimization of source material selection， dosage optimization of compatible herbs， and multi-objective optimization indicators， were discussed. Furthermore， the evaluation methods for component effects were summarized during the optimization process， so as to provide scientific and practical foundations for innovative research in TCM and the development of new drugs based on TCM compounds.

ObjectiveTo investigate the influencing factors for recompensation in patients with decompensated hepatitis C cirrhosis， and to establish a predictive model. MethodsA total of 217 patients who were diagnosed with decompensated hepatitis C cirrhosis and were admitted to The Third People’s Hospital of Kunming l from January， 2019 to December， 2022 were enrolled， among whom 63 patients who were readmitted within at least 1 year and had no portal hypertension-related complications were enrolled as recompensation group， and 154 patients without recompensation were enrolled as control group. Related clinical data were collected， and univariate and multivariate analyses were performed for the factors that may affect the occurrence of recompensation. The independent-samples t test was used for comparison of normally distributed measurement data between two groups， and the Mann-Whitney U test was used for comparison of non-normally distributed measurement data between two groups； the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. A binary Logistic regression analysis was used to investigate the influencing factors for recompensation in patients with decompensated hepatitis C cirrhosis， and the receiver operating characteristic （ROC） curve was used to assess the predictive performance of the model. ResultsAmong the 217 patients with decompensated hepatitis C cirrhosis， 63 （29.03%） had recompensation. There were significant differences between the recompensation group and the control group in HIV history （χ²=4.566， P=0.034）， history of partial splenic embolism （χ²=6.687， P=0.014）， Child-Pugh classification （χ²=11.978， P=0.003）， grade of ascites （χ²=14.229， P<0.001）， albumin （t=4.063， P<0.001）， prealbumin （Z=-3.077， P=0.002）， high-density lipoprotein （t=2.854， P=0.011）， high-sensitivity C-reactive protein （Z=-2.447， P=0.014）， prothrombin time （Z=-2.441， P=0.015）， carcinoembryonic antigen （Z=-2.113， P=0.035）， alpha-fetoprotein （AFP） （Z=-2.063， P=0.039）， CA125 （Z=-2.270， P=0.023）， TT3 （Z=-3.304， P<0.001）， TT4 （Z=-2.221， P=0.026）， CD45⁺ （Z=-2.278， P=0.023）， interleukin-5 （Z=-2.845， P=0.004）， tumor necrosis factor-α （Z=-2.176， P=0.030）， and portal vein width （Z=-5.283， P=0.005）. The multivariate analysis showed that history of partial splenic embolism （odds ratio ［OR］=3.064， P=0.049）， HIV history （OR=0.195， P=0.027）， a small amount of ascites （OR=3.390， P=0.017）， AFP （OR=1.003， P=0.004）， and portal vein width （OR=0.600， P<0.001） were independent influencing factors for the occurrence of recompensation in patients with decompensated hepatitis C cirrhosis. The ROC curve analysis showed that HIV history， grade of ascites， history of partial splenic embolism， AFP， portal vein width， and the combined predictive model of these indices had an area under the ROC curve of 0.556， 0.641， 0.560， 0.589， 0.745， and 0.817， respectively. ConclusionFor patients with decompensated hepatitis C cirrhosis， those with a history of partial splenic embolism， a small amount of ascites， and an increase in AFP level are more likely to experience recompensation， while those with a history of HIV and an increase in portal vein width are less likely to experience recompensation.

Objective:To survey the status quo and influencing factors of contracted family doctor pay services in urban communities of Suzhou city.Methods:This study was a cross-sectional study. A questionnaire survey on the status quo and influencing factors of contracted family doctor pay services was conducted from July to October 2022 among 750 residents from 40 communities of 4 subdistricts in Suzhou Gusu District, selected by stratified random sampling method. A self-designed questionnaire was used for the survey, which included demographic information, status quo of pay services among residents and factors influencing the service contracting. Chi-square test and binary logistic regression were used to analyze the influencing factors of contracted family doctor pay services.Results:A total of 750 questionnaires were distributed, with 720 valid ones returned at a recovery rate of 96.0%. Among the 720 residents, 370 (51.4%) were female, and 300 (41.7%) were between the age of 35 and 60 years old. There were 71 residents who had contracted pay services with a contracting rate of 9.9% (71/720), and the renewal rate was 80.3% (57/71). The top 3 reasons for signing the contract were health guidance (67.6%, 48/71), medical counselling (63.4%, 45/71) and 3 free consultations (57.7%, 41/71). The top 3 reasons for not signing a contract were not needing services (49.9%, 324/649), not knowing about contracted services (41.9%, 272/649) and rarely visiting the community health service center (25.6%, 166/649). Age ( χ2=21.072), marital status ( χ2=10.969), knowing the family doctor team ( χ2=145.954), knowing the family doctor contract system ( χ2=133.981), knowing the content and the rights of the contracted services ( χ2=132.905), using primary medical institutions as first choice for common and chronic diseases ( χ2=13.532), multiple comorbid chronic diseases ( χ2=30.024), being agreed by family members ( χ2=46.258), signing contract in family members ( χ2=108.833) or relatives and friends ( χ2=47.492), and experience in community health service centers ( χ2=26.116) were significantly associated with the contract signing (all P<0.05). Logistic regression analysis showed that knowing family doctor team well ( OR=23.13,95% CI:5.05-105.97) or very well( OR=95.28,95% CI: 10.71-847.68); having ≥3 chronic diseases compared to no chronic diseases ( OR=5.60, 95% CI: 1.88-16.75, P<0.05); contracting agreed by family members compared to not agreed ( OR=2.66, 95% CI: 1.03-6.84, P<0.05); signing contract in family members compared to not signing ( OR=4.42, 95% CI:2.05-9.55, P<0.05) were independent influencing factors of signing contract of family doctor pay services. Conclusions:The rate of contracted of family doctor pay services in Gusu District of Suzhou City is relatively low. Knowing the family doctor team, having multiple comorbid chronic diseases, agreement among family members, and signing contract in family members are influencing factors of contracted family doctor pay services.

OBJECTIVE To investigate the prognostic value of pre-treatment serum lactate dehydrogenase(LDH)levels in patients with locally recurrent nasopharyngeal carcinoma(NPC)treated with salvage intensity-modulated radiotherapy(IMRT)and to determine its association with rT staging.METHODS The records of 97 patients with locally relapsed and non-metastatic NPC who received salvage IMRT treatment in our center from January 2018 to April 2022 were collected,including 51 patients who died,18 patients with distant metastases,30 patients with local failure,and 67 patients with prognostic adverse events(death,distant tumors/local metastases).Clinical data,local failure-free survival(LFFS),distant metastasis-free survival(DMFS)and overall survival(OS)were obtained from all patients,and the relationship between LDH and the prognosis of salvage IMRT therapy in NPC patients was analyzed.RESULTS The serum LDH level before salvage IMRT was significantly higher in the death[221.25(178.24,339.13)U/L vs.124.82(79.0,159.50)U/L,Z=-5.122],local failure[230.75(170.89,394.50)U/L vs.157.85(91.78,216.95)U/L,Z=-3.442],distant metastasis[261.62(153.55,465.50)U/L vs.168.98(101.75,237.75)U/L,Z=-2.478]and poor prognosis group[220.05(167.20,506.16)U/L vs.93.45(69.95,154.35)U/L,Z=-6.018],and all P<0.05.Serum LDH levels were divided into dichotomous variables according to median values(≥177.50 U/L vs.<177.50 U/L),the Cox univariate model found that the hazard ratios of LDH affecting LFFS,DMFS,OS and toxic-related death(TRD)were 3.759(1.660-8.558),4.217(1.383-12.861),3.226(1.715-6.069),3.363(1.750-6.463),P<0.05.LDH remained an independent prognostic factor for LFFS,DMFS,OS,and TRD in multivariate regression analysis(P<0.05).Compared with patients with LDH<177.50 U/L,more patients in the LDH≥177.50 U/L group had local progression-related death,and the no LFFS stage,no DMFS stage and OS were shorter in the LDH≥177.50 U/L group(log rank=11.624,7.559,14.758),P<0.05.In predicting overall survival,adding LDH to the rT stage is preferable to the rT stage alone.CONCLUSION LDH is an important factor in predicting LFFS,DMFS,OS,and TRD after saving IMRT in patients with locally relapsed,non-metastatic NPC,and the value of LDH combined with rT staging in predicting overall survival is high.

BACKGROUND:In the construction of guided bone regeneration membrane with biological function,a single material cannot meet the clinical needs due to its insufficient function,so the composite of multiple materials has become a trend of tissue repair engineering. OBJECTIVE:To prepare silk fibroin/bioactive glass composite fiber membranes by electrospinning technology,and to characterize the physicochemical properties and biocompatibility in vitro. METHODS:The solution of electrospinning was prepared by dissolving 0.8 g silk fibroin protein in 10 mL hexafluoro-isopropanol alcohol,and the nanofiber membrane of silk fibroin protein was prepared by electrospinning technology(denoted as SF fiber membrane).0.1,0.3,0.5,and 0.8 g of bioactive glass were added to the electrospinning solution,and the silk fibroin/bioactive glass composite fiber membrane was prepared by electrospinning technology(recorded as SF/1BG,SF/3BG,SF/5BG,and SF/8BG fiber membrane in turn).The physicochemical properties and biocompatibility of five groups of fiber membranes were characterized. RESULTS AND CONCLUSION:(1)The scanning electron microscopy results showed that nanofibers of the prepared composite membrane were smooth,continuous and uniform and had no beaded structure.There was no obvious adhesion between the silk fibers,and they all showed random arrangement of disordered porous structures.The fiber diameter of the fiber membrane decreased after the addition of bioactive glass.Fourier infrared spectroscopy and X-ray diffraction detection results showed that the chemical structure of silk fibroin protein and bioactive glass in fiber membrane was stable.The water contact angles of SF,SF/1BG,SF/3BG,SF/5BG,and SF/8BG were 105.02°,72.58°,78.13°,79.35°,and 72.50°,respectively.(2)Bone marrow mesenchymal stem cells were inoculated on five groups of fiber membranes.CCK-8 assay results showed that SF/1BG,SF/3BG,and SF/5BG fiber membranes could promote the proliferation of bone marrow mesenchymal stem cells compared with SF and SF/8BG.Live cell/dead cell staining showed that the cell vitality on the surface of the five groups of fiber membranes was better,and the number and distribution of cells on the surface of SF/5BG fiber membrane were more uniform.Rhodamine phalloidin staining and scanning electron microscopy exhibited that compared with SF fiber membrane,the SF/5BG fiber membrane was more favorable to the adhesion of bone marrow mesenchymal stem cells.Bone marrow mesenchymal stem cells were inoculated on the fiber membrane of the five groups for osteogenic induction differentiation,and the alkaline phosphatase activity of the SF/3BG and SF/5BG groups was higher than that of the other three groups(P＜0.05,P＜0.01,P＜0.001).Alizarin red staining showed that the formation of calcium nodules in fiber membrane increased after the addition of bioactive glass,and the formation of calcium nodules in the SF/5BG group was the most.(3)The results show that silk fibroin/bioactive glass composite fiber membrane has good biosafety and biocompatibility.

Objective:To describe the current situation of blood glucose control in 18-64 year-old people with type 2 diabetes in the Shenzhen community and analyze the influencing factors to provide a reference for enhancing the management effect of type 2 diabetes in community health service institutions.Methods:The data were from the Shenzhen Community Health Service Information System. A cross-sectional survey design was adopted to include 18-64 year-old patients with type 2 diabetes in Shenzhen community health service institutions in 2022. The blood glucose control rate was calculated through the physical examination data recorded by the information system in 2022, and the influencing factors of blood glucose control in this group of patients were analyzed using a multivariate logistic regression model.Results:A total of 120 174 patients were included in the study. The blood glucose control rate was 53.04%. The results of multivariate logistic regression analysis showed that women ( OR=1.07, 95% CI: 1.04-1.10), ages 45-54 ( OR=1.10, 95% CI: 1.01-1.19), 55-64 ( OR=1.24, 95% CI: 1.14-1.35), middle school ( OR=1.09, 95% CI: 1.05-1.13), high school and technical secondary school ( OR=1.26, 95% CI: 1.21-1.31), junior college or above ( OR=1.75, 95% CI: 1.67-1.83), basic medical insurance for urban employees ( OR=1.05, 95% CI: 1.01-1.08), weekly exercise ( OR=1.26, 95% CI: 1.22-1.31), daily exercise ( OR=1.31, 95% CI: 1.28-1.35) and combined hypertension ( OR=1.21, 95% CI: 1.18-1.24) were more likely to reach the standard of blood glucose control; while unmarried ( OR=0.85, 95% CI: 0.77-0.95), divorced ( OR=0.84, 95% CI: 0.73-0.97), insurance status was fully self-funded ( OR=0.95, 95% CI: 0.91-0.99), disease duration was 5- years ( OR=0.65, 95% CI: 0.63-0.66), ≥10 years ( OR=0.41, 95% CI: 0.39-0.42), the treatment method was diabetes drug therapy ( OR=0.74, 95% CI: 0.71-0.76), low weight ( OR=0.89, 95% CI: 0.80-1.00), obese group ( OR=0.85, 95% CI: 0.82-0.88), combined with central obesity ( OR=0.83, 95% CI: 0.81-0.86), combined with dyslipidemia ( OR=0.69, 95% CI: 0.68-0.71), current smoking ( OR=0.74, 95% CI: 0.72-0.77), and current drinking ( OR=0.97, 95% CI: 0.93-1.00) were less likely to reach the standard of blood glucose control. Conclusions:The blood glucose control rate of 18-64 year-old people with type 2 diabetes in Shenzhen still has room for improvement. More attention should be paid to 18-64 year-old patients with type 2 diabetes, especially for patients with dyslipidemia, central obesity, and diabetes with a long course, and supervision and guidance should be strengthened for patients with bad habits such as smoking, drinking alcohol, and lack of exercise.

Objective:To analyze the disease burden in middle-aged and elderly population aged ≥55 in Shenzhen from 2016 to 2030 and provide evidence for the development of healthy aging strategies.Methods:The years of life lost (YLL), years lost due to disability (YLD), and the disability-adjusted life year (DALY) in this population from 2016 to 2022 were calculated. Joinpoint log-linear regression model was used to analyze the time trend. Bayesian age-period-cohort model and grey system model were used to predict YLL, YLD, and DALY in this population in 2030.Results:From 2016 to 2022, the crude DALY rate showed a transient fluctuation in age group 55-74 years, but a pronounced increase in age group ≥85 years. The proportions of YLL and YLD due to non-communicable diseases in all age groups was considerably higher than those due to communicable and nutritional diseases and injuries. In 2022, in all age groups, the YLL due to neoplasms (55-74 years old) and cardiovascular disease (≥75 years old) ranked first, and the YLD due to musculoskeletal disorder ranked first. By 2030, the causes of YLL and YLD ranking first in each age group would be remained, while the ranks of some causes would increase.Conclusions:The age specific characteristics of current and predicted disease burden differed in individuals aged ≥55 years. Therefore, it is necessary to allocate social and medical resources according to the disease burden pattern.

OBJECTIVE To develop a magnetic resonance(MRI) imaging radiomics and clinical factor model to predict recurrence and metastasis in patients with primary stage Ⅱ-Ⅳa nasopharyngeal carcinoma(NPC) and to validate its predictive effect on adjuvant chemotherapy(AC) outcomes. METHODS A retrospective analysis was performed on 135 patients with stage Ⅱ to Ⅳa NPC diagnosed in Longgang Otolaryngology Hospital of Shenzhen City from February 2018 to October 2021. After receiving standard synchronous radiotherapy and chemotherapy at our hospital,some patients received induction chemotherapy and/or AC based on cisplatin/nedaplatin. The imaging features of enhanced MRI sequences were extracted using PyRadiomics platform. Using the least absolute shrinkage and selection operator(LASSO) algorithm to filter features associated with recurrence or metastasis,a clinical radiomics model(CRM) was constructed by Cox multivariate analysis in a training cohort and validated in a validation cohort. All patients were divided into high-risk and low-risk groups based on the model's median Rad score. Kaplan-Meier survival curves were used to compare 3-year recurrence or metastasis free survival(RMFS) in patients with AC in high-risk group and low risk-group. RESULTS A total of 960 imaging features were extracted. The CRM consists of 9 features(6 imaging features and 3 clinical factors). In the training cohort,the area under the CRM curve(AUC) of 3-year RMFS was 0.867(P<0.001),and the sensitivity and specificity were 90.32％ and 79.66％,respectively. In the validation cohort,the AUC was 0.836(P<0.001) and the sensitivity and specificity were 100.0％ and 71.43％,respectively. The 3-year RMFS in high-risk and low-risk groups was 42.86％(27/63) and 94.44％(68/72)(log rank=50.818,P<0.001),respectively. Among CRM high-risk patients,3-year RMFS was significantly better in patients who received AC than those who did not(log rank=6.204,P=0.013). CONCLUSION CRM based on 3 clinical factors and 6 MRI features provides a non-invasive method for predicting the prognosis of NPC,which may help guide treatment decisions for clinical adjuvant chemotherapy,but further external verification is needed.

Different sagittal and vertical malocclusions exhibit different characteristics in the growth,development,and final morphol-ogy of the temporomandibular joint.Different skeletal malocclusions affect the spatial and morphological characteristics of the final tem-poromandibular joint through different growth and development mechanisms.These mechanisms have important guiding significance for determining the etiology and guiding treatment plans of maxillofacial malocclusion in children and adolescents in clinical practice.This article summarized and analyzed morphological differences of the temporomandibular joint fossa and condyle in different sagittal and ver-tical malocclusions,as well as the relative position of the condyle in the fossa.It is found that there is a connection between different maxillofacial malocclusions and the characteristics of the temporomandibular joint,with the vertical direction having a more significant impact on the temporomandibular joint than the sagittal direction;the impact of vertical malocclusion on the temporomandibular joint is mainly reflected in the shape of the joint fossa and the position of the condyle in the fossa.The joint fossa of hyperdivergent malocclu-sion is often relatively low and flat,with the condyle located in the anterior upper position of the fossa.The joint fossa of hypodivergent is relatively narrow and deep,and the condyle is relatively backward and lower in the joint fossa.The possible mechanisms were also elaborated,providing reference for clinicians'comprehensive diagnosis and treatment.
