Data analysis models may assist the transmission of traditional Chinese medicine （TCM） experience and clinical diagnosis and treatment， and the possibility of constructing a “data-knowledge” dual-drive model was explored by taking gastric precancerous state as an example. Data-driven is to make clinical decisions around data analysis， and its syndrome-differentiation decision-making research relies on hidden structural models and partially observable Markov decision-making processes to identify the etiology of diseases， syndrome elements， evolution of pathogenesis， and syndrome differentiation protocols； knowledge-driven is to make use of data and information to promote decision-making and action processes， and its syndrome-differentiation decision-making research relies on convolutional neural networks to improve the accuracy of local disease identification and syndrome differentiation. The “data-knowledge” dual-driven model can make up for the shortcomings of single-drive numerical simulation accuracy， and achieve a balance between local disease identification and macroscopic syndrome differentiation. On the basis of previous research， we explored the construction method of diagnostic assisted decision-making platform for gastric precancerous state， and believed that the diagnostic and decision-making ability of doctors can be extended through the assistance of machines and algorithms. Meanwhile， the related research methods were integrated and the core features of gastric precancerous state based on TCM syndrome differentiation and endoscopic pathology diagnosis and prediction were obtained， and the elements of endoscopic pathology recognition based on TCM syndrome differentiation were explored， so as to provide ideas for the in-depth research and innovative application of cutting-edge data analysis technology in the field of intelligent TCM syndrome differentiation.

Objective:To systematically evaluate the clinical efficacy of Ruiyun procedure for hemorrhoids(RPH)combined with milligan-morgan hemorrhoidectomy(MMH)in the treatment of mixed hemorrhoids compared with MMH alone.Methods:Relevant literature was retrieved from China National Knowledge Infrastructure(CNKI),Wanfang,and VIP databases from their establishment to Jan 2023 using computers.Clinical randomized controlled trials(RCTs)of RPH combined with MMH and MMH alone in the treatment of mixed hemorrhoids were selected and analyzed,and meta-analysis was conducted using RevMan5.3 software.Results:A total of 30 RCTs were included,involving 4 609 patients.Results of Meta-analysis showed that there were statistically significant differences in surgical efficacy(RR=1.05,95% CI:1.02-1.08,P= 0.003),postoperative margin edema(RR=0.36,95% CI:0.27-0.49,P＜0.01),postoperative anal pain(RR=0.35,95% CI:0.23-0.53,P＜0.01),postoperative rectal bleeding(RR=0.35,95% CI:0.17-0.72,P=0.004),postoperative anal stenosis(RR=0.26,95% CI:0.11-0.59,P=0.001)and postoperative urinary retention(RR=0.77,95% CI:0.63-0.93,P=0.007)between RPH combined with MMH group and MMH group.Conclusion:Compared with MMH alone,RPH combined with MMH in the treatment of mixed hemorrhoids can reduce the incidence of postoperative side effects,such as postoperative margin edema,anal pain,rectal bleeding,anal stenosis,and urinary retention,with a relatively higher efficiency.

AIM:To investigate the influencing factors of abnormal telangiectasia secondary to diabetic retinopathy(DR).METHODS: Prospective studies. A total of 153 cases(240 eyes)with DR treated in our hospital from January 2021 to January 2023 were selected to analyze the risk factors of abnormal telangiectasia secondary to DR and its predictive efficacy.RESULTS: The patients were divided into dilated group(77 eyes of 40 cases)and non-dilated group(163 eyes of 113 cases)according to whether they had secondary abnormal telangiectasia. There were significant differences in diabetic macular edema, hard exudates grade and fasting blood glucose level between the two groups(P<0.05). Logistic regression analysis showed that diabetic macular edema, high hard exudates grade and high blood glucose level were the risk factors for abnormal telangiectasia secondary to DR(P<0.05).CONCLUSION: The occurrence of telangiectasia secondary to DR may be related to diabetic macular edema, grade 3 hard exudates and high blood glucose level.

As a new type of immunosuppressant，iguratimod can mediate the anti-inflammatory signaling pathway by inhibiting the proliferation of inflammatory cells and reducing the release of inflammatory cytokines， and play the role of anti-inflammatory. It can affect the proliferation of immune cells and the expression of immune factors，reduce the production and deposition of immune complexes in the body，and play the role of immune regulation. It can regulate bone metabolism by mediating signaling pathways such as Wnt/β-catenin，Toll-like receptor 4/nuclear factor-κB and osteoprotegerin/nuclear factor-κB receptor activating factor ligand， and play a role in bone protection. It can inhibit pulmonary fibrosis by inhibiting the expression of transforming growth factor β1/ Smad2/3 signaling pathway，tumor necrosis factor-α，interleukin-1，interleukin-6，matrix metalloproteinase-9 and other inflammatory cytokines in lung tissue，and inhibiting the expression of collagen and fibronectin. Its efficacy and safety have been confirmed in the clinical application of rheumatoid arthritis and primary Sjogren syndrome and included in the diagnosis and treatment of the disease.

OBJECTIVE To observe the efficacy of cetrorelix combined with aspirin in preventing early-onset ovarian hyperstimulation syndrome （OHSS）. METHODS A retrospective analysis was conducted on clinical data from 38 early-onset OHSS patients， who received treatment in our hospital from January 1st to July 1st， 2022. These patients were divided into intervention group （19 cases） and control group （19 cases） according to the therapy regimen. On the first day after oocyte retrieval surgery， the control group was given aspirin enteric-coated tablets 100 mg orally until menstruation began. The intervention group was given cetrorelix for injection 0.25 mg subcutaneously， for consecutive 3 days+aspirin enteric-coated tablets （same usage and dosage as the control group）. The first luteal phase， the degree of OHSS， and the ovarian volume， ascites volume， serum estradiol （E2）， white blood cell count （WBC）， hematocrit （HCT）， neutrophil ratio （NEUT%）， D-dimer （DD）， prothrombin time （PT）， fibrinogen （Fib） after oocyte retrieval surgery were observed and measured in 2 groups. RESULTS The first luteal phase was significantly shorter， and the proportions of median and severe OHSS cases were significantly lower in the intervention group compared to the control group （P＜0.05 or P＜0.01）. After oocyte retrieval surgery， the intervention group showed significantly lower ovarian volume， ascites volume， serum E2， WBC， NEUT%， HCT， DD and Fib compared to the control group， but PT of intervention group was signiticantly higher than that of control group （P＜0.05）. CONCLUSIONS Cetrorelix combined with aspirin is more effective in preventing early-onset OHSS than aspirin alone.

Pathogenesis and treatment methods of qi-ying fen transformation in warm diseases are explored.It is believed that warm diseases are caused by yang pathogenic factors and are most likely to damage the organs and body fluids.Body fluids,as important components of human body's healthy qi,are usually present in the lungs as lung fluids,in the stomach as stomach fluids,in the intes-tines as intestinal fluids,and in blood vessels as nutrient yin.During the transformation from qi fen syndrome to ying fen syndrome,vis-ceral parenchymal damage acts as its important pathological mechanism and fluid depletion in blood vessels is an important reason for exacerbating qi-ying fen transformation.Excessive fire-toxicity,as an initial factor,promotes qi-ying fen transformation.Fluid deple-tion is the pathological basis for exacerbating qi-ying fen transformation.Clearing heat and protecting fluids,with sweet-flavored and cold-natured drugs to generate fluids,salty-flavored and cold-natured drugs to clear heat,and combination of sweet-flavored and bit-ter-flavored drugs,is an inevitable treatment method for preventing and treating qi-ying fen transformation in warm diseases,and it al-so has important clinical guidance value for internal miscellaneous diseases and acute severe cases.

Sensory dysfunction is a common clinical problem for children with cerebral palsy.Proprioception plays a key role in maintaining postural adjustment and balance coordination, so proprioceptive assessment is of great significance for further rehabilitation of children with cerebral palsy.At present, proprioception assessment is mainly used in adults such as stroke and joint injury, but there is still a lack of research in children, especially in children with cerebral palsy.Therefore, this paper aims to review the evaluation of proprioception of children with cerebral palsy at home and abroad.

Objective To study the distribution and trend of HIV-1 drug resistance mutation in Dalian blood donors be-tween 2011 and 2020.Methods The protease-reverse transcriptase(PR-RT)region was sequenced in Dalian blood donors tested HIV-1 positive between 2011 and 2020.Drug resistance mutation(DRM)rate and level of resistance to selected drugs were analyzed by the Stanford HIV Drug Resistance Database.Results DRM were detected in 17.2%(30/174)of samples,while transmitted drug resistance(TDR)was5.7%(10/174).Between2011 and2020,DRM and TDR rates in-creased significantly in 2019 and reached their highest levels in 2020(44.4%and 22.2%,respectively).DRM carriage was associated with people with college degree or above and with local residents(P<0.05).NNRTI DRMs were the most fre-quently detected(12.6%,22/174),followed by PIs(5.7%,10/174),with V179D/E/T and M46I being the main DRMs detected.Only one HIV-1strain(0.57%,1/174)carried a NRTI DRM(L74I).The overall rate of predicted high level re-sistance to antiretroviral drugs was 6.9%(12/174),with the highest proportion of NNRTI resistance(83.3%,10/12).Two samples were classified as highly resistant to EFV and NVP,accounting for 1.1%(2/174).CRF55_01B strains showed a significantly higher DRM rate than strains of other HIV-1 genotypes(P<0.05).Conclusion Between 2011 and 2020,the rate of HIV-1 DRMs in blood donors in Dalian showed a significant upward trend,particularly in 2019-2020,with NNRTI resistance being the most common.The combination of DRMs detection before and after implementation of ART un-der the latest national ART treatment plan would improve the effectiveness of HIV-1 prevention and control locally.

Objective:To construct a prediction model for ventilator-associated pneumonia (VAP) in mechanically ventilated preterm infants in the neonatal intensive care unit (NICU) and to test its clinical effect.Methods:This was a cross-sectional study. A total of 740 preterm infants admitted to the NICU for mechanical ventilation from July 2018 to June 2023 were retrospectively selected as the study subjects, and were divided into the modeling set (518 cases) and the validation set (222 cases) according to the ratio of 7∶3 using the computer-generated random number method. The modeling set was divided into the VAP group (181 cases) and the non-VAP group (337 cases) according to whether VAP occured, and 21 clinical characteristics were analyzed, using single factor difference analysis to screen predictive factors, the independent risk factors of VAP in mechanically ventilated preterm infants were determined by multivariate Logistic regression analysis, and the nomogram model was made by R software. Then, the nomogram model was tested by validating the data of the validation set. The receiver operating characteristic (ROC) curve, Hosmer-Lemeshow goodness-of-fit test, calibration curve and clinical decision curve were used to evaluate the efficacy and practical value of the model.Results:There were 88 males and 93 females in the VAP group, with 156 cases of gestational age<34 weeks and 25 cases of gestational age≥34 weeks. There were 155 males and 182 females in the non-VAP group, with 196 cases of gestational age<34 weeks and 141 cases of gestational age≥34 weeks. Birth weight ( OR=0.114, 95% CI 0.044-0.268, P<0.05) and oral care of breast milk ( OR=0.124, 95% CI 0.0.057-0.249, P<0.05) were protective factors for VAP in mechanically ventilated preterm infants, and Apgar score at 5 min after birth ( OR=2.895, 95% CI 1.318-6.419, P<0.05), serum prealbumin at 72 h of mechanical ventilation ( OR=4.837, 95% CI 2.643-9.063, P<0.05), gastric contents reflux ( OR=6.754, 95% CI 3.156-15.240, P<0.05), and time of mechanical ventilation ( OR=7.784, 95% CI 3.491-18.160, P<0.05) were independent risk factors for VAP in mechanically ventilated preterm infants. The area under the curve (AUC) of the ROC curve of the modeling set was 0.929 (95% CI 0.907-0.950, P<0.01), and the validation set (AUC) was 0.917 (95% CI 0.882-0.952, P<0.01), the model has good discrimination. The C indices of the modeling set and the validation set were 0.93 and 0.92 respectively by sampling 500 times by the Bootstrap method, indicating that the model had good consistency, and the decision curve suggested that the prediction model was far from the extreme curve and the net return value was high, indicating that the nomogram prediction model constructed this time had high prediction value. Conclusions:Birth weight, Apgar score at 5 min after birth, time of mechanical ventilation, oral care of breast milk, serum prealbumin at 72 h of mechanical ventilation, and gastric contents reflux are independent influencing factors for VAP in mechanically ventilated preterm infants. The nomogram prediction model constructed can provide a visual and simple evaluation tool for early identification of high-risk children and reducing the occurrence of VAP.

Objective To explore the relationship between the triglyceride-glucose(TyG)index,residual cholesterol(RC)and dia-betic nephropathy(T2DM).Methods A total of 410 patients with T2DM were consecutively selected from the Endocrinology Depart-ment of Jiangsu Provincial Traditional Chinese Medicine Hospital from March 2022 to March 2023.The patients were stratified into three groups based on their morning urinary albumin-to-creatinine ratio(UACR):269 patients were in simple diabetes mellitus(SDM)group,80 in early diabetic nephropathy(EDN)group and 61 in clinical diabetic nephropathy(CDN)group.Comparative an-alyses were conducted on the three groups in terms of gender,age,past medical history,body mass index(BMI),systolic blood pres-sure(SBP),diastolic blood pressure(DBP),fasting blood glucose(FBG),Urea,creatinine(Cr),urinary albumin(UA)total cholesterol(TC),triglycerides(TG),high-density lipoprotein cholesterol(HDL-C),and low-density lipoprotein cholesterol(LDL-C).Additionally,TyG index and RC were calculated.Spearman analysis was employed to evaluate the correlation between UACR and these various parameters.Binary Logistic regression was utilized to identify independent risk factors for diabetic nephropathy(DN).The diagnostic performances of Urea,Cr,TyG index and RC for type 2 diabetic nephropathy were assessed using receiver operating charac-teristic(ROC)curve analyses.Results Compared with SDM group,diabetes duration,SBP,Urea,UA,TG,TC,TyG index and RC showed significant increases in EDN group with statistically significant differences(P＜0.05),and diabetes duration,SBP,DBP,Urea,Cr,UA,TG,TC,LDL-C,TyG index and RC in CDN group also exhibited significant increases,with statistically significant differences(P＜0.05).Spearman rank correlation analysis revealed a positive correlation between RC and UACR(r=0.278,P＜0.001),a positive correlation between TyG index and UACR(r=0.239,P＜0.001)and a positive correlation between RC and TyG in-dex(r=0.562,P＜0.001).Binary logistic regression analysis showed that diabetes duration,SBP,Urea,Cr,TyG index(OR=2.815,95％CI:1.481-5.349,P=0.002),and RC(OR=2.179,95％CI:1.038-4.574,P=0.04)were independent risk factors for DN.The area under the ROC curve(AUCROC)for RC predicting DN occurrence was 0.670(95％CI:0.616-0.725),while the AUCROC for the TyG index was 0.620(95％CI:0.564-0.676).Conclusion TyG index and RC were significantly correlated with the development of DN in the patients with T2DM,which may early facilitate clinical identification and management for the patients in the risk ofr diabetic kidney disease.
