ObjectiveThe research focuses on developing modeling and evaluation methodologies for an animal model exhibiting spleen deficiency and dampness excess syndrome， with the aim of standardizing such animal models for future reference. MethodsBy conducting a literature search on animal models of spleen deficiency and dampness excess syndrome， relevant publications meeting inclusion and exclusion criteria will be identified based on publication date， data source， types of diseases involved， animal characteristics， modeling methods， modeling duration， macroscopic syndrome assessment indicators， macroscopic quantification indicators， laboratory testing parameters， intervention approaches， positive controls and application context. A database will be established to facilitate the extraction of this information for quantitative analysis， statistical evaluation， and visual representation. ResultsA total of 137 literature articles meeting the standards have been included in the research. The primary animal species used in animal models of spleen deficiency and dampness excess are SD rats. Modeling methods include single-factor， dual-factor composite， and triple-factor composite methods， with various models widely applied in validation of pharmacological effects and mechanistic explorations. Evaluation indices of animal models for spleen deficiency and dampness excess primarily consist of macroscopic syndrome evaluation indicators and macroscopic quantitative indicators. Laboratory testing indicators are mostly related to research areas such as fluid metabolism and gastrointestinal function. The most commonly studied herbal formulas currently include Shenling Baizhu San and Pingwei San， with natural recovery and the use of the western medicine metronidazole as the most frequently used positive controls. ConclusionThe application of animal models for spleen deficiency and dampness excess is gradually increasing， with various modeling methods already simulating the typical characteristics of this syndrome pattern. However， there are still many areas that are worth contemplating and improving. This study aims to provide reference and ideas for the standardization of symptom names in animal models of spleen deficiency and dampness excess， as well as for the improvement of model construction and evaluation systems.

Objective:To study a method for automatically extracting acupuncture and moxibustion prescriptions from clinical literature to assist data mining of acupuncture and moxibustion prescriptions; To support clinical research and decision-making in acupuncture and moxibustion treatment.Methods:The Chinese journal articles on clinical trials of acupuncture and moxibustion in CNKI from January 1, 1992 to December 31, 2022 were searched. The titles and abstracts of 750 articles were randomly selected and manually labeled. The three main entities of disease name, acupuncture and moxibustion method and acupoint of acupuncture and moxibustion prescription were selected. From the data set, 70% was selected as the training set, 15% as the validation set, and 15% as the test set for the experiment. The extraction of acupuncture prescriptions was considered a sequence labeling task. A model for automatic extraction of acupuncture prescriptions was built using a pretrained language model (PLM), and four different PLMs were selected to compare their entity recognition effects. The impact of negative sampling and label smoothing training techniques on the model was further investigated.Results:The model based on eHealth had the highest F1 scores (92.84). During training, if only negative sampling technology was used, F1 value increased to 93.53; if only label smoothing was used, F1 value increased to 93.64; if negative sampling and label smoothing were used simultaneously, F1 value increased to 94.28, an increase of 1.55%. Conclusions:This study proposes a fast and accurate model for extracting acupuncture and moxibustion prescriptions. The research shows that the model recognition effect based on eHealth in the biomedical field is the best, and the recognition effect of the model can be further improved by using negative sampling and label smoothing training techniques.

Objective:To investigate the prevalence of influenza, pneumococcal, hepatitis B virus (HBV), human papillomavirus (HPV), and varicella zoster virus (VZV) vaccination in patients with systemic lupus erythematosus (SLE), and to analyze the factors related to vaccination.Methods:Data were obtained from 1 203 patients with SLE, via a multi-center web-based survey using an online questionnaire. Data about their social conditions, clinical presentations, willingness for being vaccinated, vaccination within 5 years were collected. Demographic data were shown by descriptive analysis. Chi-square and logistic regression analysis were used to assess the power of related indexes as predictors of vaccination.Results:The vaccination rates of influenza, pneumococcal, HBV, HPV, and VZV were 5.49% (66/1 203), 0.66% (8/1 203), 2.08% (25/1 203), 3.82% (46/1 203), and 0.17% (2/1 203), respectively. Data analysis showed that higher education ( χ2=30.94, P<0.001) and higher income ( χ2=10.70, P=0.001) had greater effects on influenza vaccination. There was a relationship between HPV vaccination and higher education ( χ2=20.96, P<0.001), higher income ( χ2=20.56, P<0.001), younger age ( χ2=8.54, P=0.001), and single ( χ2=5.63, P=0.018). Male ( χ2=10.27, P=0.001) and higher education ( χ2=4.52, P=0.034) were associated with HBV vaccination. The multivariate logistic regression analysis revealed that higher education [ OR (95% CI)=2.14 (1.10, 4.18), P=0.026], having children under 18 years-old [ OR(95% CI)=1.802(1.02, 3.18), P=0.042], and hydroxychloroquine usage [ OR(95% CI)=2.55(1.06, 6.15), P=0.037], had a positive correlation with influenza vaccination. Male [ OR(95% CI)=4.24(1.37, 13.08), P=0.012], had an impact on HBV vaccination. The factors related to HPV vaccination included age <45 [ OR (95% CI)=0.93(0.89, 0.97), P=0.001], higher education [ OR(95% CI)=2.28(1.11, 4.65), P=0.024], higher income [ OR(95% CI)=2.68(1.32, 3.41), P=0.006] and the usage of immunosuppressive agents [ OR(95% CI)=1.92(1.03, 3.59), P=0.041]. Conclusion:The prevalence of vaccination in patients with SLE is low. Patients with higher education and income are more likely to being vaccinated.

Objective:To investigate the role of conjunctival impression cytology in the diagnosis of Sj?gren's syndrome (SS) and the immunological factors influencing conjunctival lesions.Methods:A total of 57 patients complaining about dry eye were collected, including 38 patients with primary Sj?gren's syndrome (pSS) and 19 patients with non-SS. Conjunctival impression cytology tests were performed for all patients, and they were scored by the Nelson method. Thirty-one patients with SS underwent serological tests such as autoantibodies, immunoglobulins, and complement. The correlation between the relevant data was compared using the t test and the rank sum test. Results:The Nelson grade ≥2 is the positive cut-off value for the diagnosis of SS. The sensitivity was 68.4%, and the specificity was 89.5%, and the area under the receiver operating characteristic curve (ROC) was 0.767. In patients with SS, there was statistical correlation between the results of conjunctival impression cytology and antinuclear antibody (ANA) ( χ2=4.664, P=0.031), anti-SSA antibody ( χ2=8.58, P<0.01), anti-SSB antibody ( χ2=6.13, P=0.013), anti-SSA-52 antibody ( χ2=6.48, P=0.011), immunoglobulin (Ig)G ( t=-4.344, P<0.01) and rheumatoid factor (RF) ( U=25.0, P<0.01). Conclusion:Con-junctival impression cytology has certain value in the diagnosis of SS and can be used to evaluate conjunctival lesions in SS. Serum ANA, anti-SSA antibody, anti-SSB antibody, anti-SSA-52 antibody, IgG, and RF levels are significantly associated with the degree of conjunctival lesions, and can be considered as an indirect evidence of conjunctival involvement in SS.

Objective To summary the risk factors,clinical characteristics and treatment of acute colonic pseudo-obstruction (ACPO) after cesarean section(CS).Methods The case group enrolled 11 patients who were diagnosed with ACPO after cesarean section in the First Affiliated Hospital of University of Science and Technology of China from January 2006 to January 2018.Another 55 patients without ACPO after CS,performed within two weeks' difference from the case group,were randomly selected as the control group.Clinical data of all subjects were analyzed retrospectively.Potential clinical risk factors were statistically analyzed.T test,Chi-square test and logistic regression analysis were used for statistical analysis.Results In the case group,the abdominal distension presented on 2 d (n=1),3 d (n=7),4 d (n=2) and 17 d (n=1) respectively after CS,and all cases experienced abdominal pain and nausea.Vomiting was reported in some cases.Plain abdominal X-ray images revealed pneumocolon with colon pouch.The maximum diameter of cecum was 6 to 12 cm.Air-liquid levels were observed in two patients.All patients underwent fasting,gastrointestinal decompression,intravenous fluid infusion,correction of electrolyte imbalance,hypertonic saline enema and prophylactic antibiotic treatment.The disease condition lasted two to six days in these patients.Conservative treatment was successful in eight patients and failed in the other three who later went for operations.The maximum cecal diameters in the three patients who underwent surgery were all ≥ 9 cm,among whom one case progressed quickly and laparotomy was tempted to rule out mechanical intestinal obstruction.In this case,the pressure was successfully reduced by placing a thoracic catheter through the anus after the failure of intestinal puncture trying to release the gases.One patient underwent colostomy due to positive signs of peritoneal irritation after a failure of four-day conservative treatment.One patient suffered a relapse after having been treated conservatively for five days,and then underwent surgeries of resection of ileocecum,distal closure of the colon ascendens plus terminal ileostomy due to intestinal perforation.Multivariate logistic regression analysis showed that higher postoperative leukocyte count (OR=1.38,95％CI:1.12-1.71,P=0.003) and postoperative body temperature ＞38 ℃ (OR=6.47,95％CI:1.06-39.61,P=0.044) were the risk factors for ACPO after CS.Conclusions Elevated leukocyte count and body temperature ＞38 ℃ were two high-risk factors for ACPO after CS.ACPO is characterized by acute onset,and the first choice is conservative management.Active surgical treatment would be required if conservative treatment fails,especially when the maximum diameter of the cecum is ≥ 9 cm,which may increase the incidence of intestinal necrosis or perforation.

Objective To investigate the clinical and immunological features of primary Sj(o)gren's syndrome (pSS) in both sexs,and to find out the pathophysiology of pSS.Methods Clinical data of 110 pSS cases were analyzed retrospectively,and cytokine levels of interleukin (IL)-2,IL-4,IL-6,IL-10,IL-17A,Tumour necrosis factor (TNF)-α,interferon (IFN)-α were measured (male=20,female=90) in patients and healthy controls (n=30) using enzyme linked immunosorbent assay (ELISA).Results Compared with female patients,no significant difference was found in male patientsin symptoms of dry mouth and dry eye (90.0％ vs 98.9％,x2=4.874,P＞0.05);the frequency of parotid gland enlargement and lymphadenectasis were higher in male (40.0％ vs 5.6％,x2=18.629,P＜0.01;25.0％ vs 6.7％,x3=6.111,P＜0.05);and the level of immunoglobu lin (Ig)A and C4 [2.2(1.5,3.0) g/L vs 3.3(2.5,5.0) g/L,Z=-3.119,P＜0.01;(0.15±0.05) g/L vs (0.19±0.08) g/L,t=-2.659,P＜0.05] were lower in male,as well as the incidence of positive anti SSA/SSB antibodies (55.0％ vs 78.8％,x2=4.921,P＜0.05).Cytokine levels of IL-2,IL-6,TNF-α (t=-3.783,-6.193,-2.065,P＜0.05) were higher in pSS than HC.Compared with female patients,cytokine levels of IL-10,IFN-γ (t=-1.075,6.286,P＜0.05) were higher in male,however,the levels of IL-2,TNF-o (t=-3.472,-5.867,P＜0.01) were lower in male.Conclusion There are differences in the cytokine levels secreted from Thl and Th2 cell between male and female patients of pSS,which may relate to the clinical and immunological characteristics and can help to reveal the pathophysiology of pSS.

Objective To investigate the characteristics of epidemic and genotype/subtype distribution of hepatitis C virus (HCV) among entry travelers at Tengchong port,to provide references for HCV prophylaxis and treatment.Methods A total of 54 serum samples were collected from anti-HCV positive travelers at Tengchong port from June 2009 to June 2016.HCV NS5B gene was amplified using reverse transcription polyonerase chain reation (RT-PCR) and subsequently sequenced.Based on the obtained sequences and retrieved reference sequences,phylogenetic analysis was conducted to determine HCV genotype/subtype.Results HCV infection rate among entry travelers at Tengchong ports was 0.45 ％ (54/12 059).Forty five samples were successfully genotyped.Phylogenetically,HCV genotype 3b was revealed to be the predominant subtype (28.89 ％,13/45) in this population,followed by genotype 6n (20.0％,9/45),genotype 1b (17.78％,8/45),genotype 3a (13.33％,6/45),genotype 2a (11.11％,5/45),genotype 1a (2.22％,1/45) and genotype 6a (2.22％,1/45).The major genotype in Myanmar travelers was genotype 6,while in Chinese population,genotype 1 predominated.Genotype 6 in the population showed close phylogenetic relationship with strains prevalent in China and Southeast Asia.Genotype 3 was closely clustered with strains prevalent in China.Conclusions The distribution of HCV genotypes among entry travelers at Tengchong port is impacted by HCV epidemic strains both in Yunnan province and neighboring regions.This population serves as a transmitting media which may influence the epidemiological characteristics of HCV in Tengchong and neighboring areas.

Objective To evaluated the value of hysteroscopy and dilatation and curettage (DC) in diagnosis of endometrial cancer. Methods This retrospective analysis included clinical pathologic data of 3 676 patients with endometrial cancer from Jan. 1, 2000 to Dec. 31, 2010 in hospitals of endometrial cancer prevention projects in Guangdong Province. Results A total of 3 676 patients with endometrial cancer were divided into DC group (3 211 patients) and hysteroscopy group (465 patients). Compared to the results of pathological diagnosis, the accuracy rate between DC group and in hysteroscopy group were no statistically difference was 91.00%(2 922/3 211) vs 90.75%(422/465;χ2=0.030, P=0.862). The accuracy rate, sensitivity, specificity, positive predictive value and negative predictive value of cervical involvement between DC group and hysteroscopy group were 81.28%vs 86.45%(P<0.01), 24.78%vs 23.68%(P>0.05), 93.76%vs 98.71%(P<0.01),46.75%vs 78.26%(P<0.01) and 84.95%vs 86.88%(P>0.05), respectively. Rate of positive peritoneal cytology in DC group was 4.76%(153/3 211), and the rate was 3.23%(15/465) in hysteroscopy group, which were no statistically difference (χ2=2.206, P=0.137). There were no statistically difference in 5-year overall survival (91.02% vs 92.03%;χ2=0.033, P=0.856) and 5-year progression-free survival (89.81%vs 91.83%;χ2=1.508, P=0.219) between DC group and hysteroscopy group. Conclusions Hysteroscopy and dilatation and curettage is an effective method in diagnosis of endometrial cancer, especially hysteroscopy is better in diagnosis of cervical involvement. Hysteroscopy don′t improve risks of positive peritoneal cytology and don′t affect the prognosis of patients with endometrial cancer.

Objective To evaluate the clinical efficacy and safety of flexible fiberoptic bronchoscopy (FFB) and bronchoalveolar lavage (BAL) in treatment of neonatal atelectasis.Methods Eligible patients, who were diagnosed as neonatal pulmonary atelectasis and admitted consecutively to the neonatal intensive care unit of the Children's Hospital of Hebei Province from January 2013 to January 2015, were included in the study.They were randomly assigned to FFB group (n=30) and control group (n=28).Newborns in the FFB group received BAL under FFB, while those controls received tracheal irrigation after intubation.The duration of lung recruitment, oxygen exposure and antibiotic administration, hospital stay, culture results of respiratory secretions, prognosis and total expenses during hospitalization were compared between the two groups.Complications of FFB were also recorded.Chi-square test and t-test were performed for statistical analysis.Results (1) In the FFB group, atelectasis occurred in the upper fight lobe (n=26), upper lobes of both sides (n=1), lower right lobe (n=2) and lower left lobe (n=1), while in the control group, atelectasis occurred in the upper right lobe (n=26), lower left lobe (n=1) and middle right lobe (n=2) (x2=0.094, P ＞ 0.05).(2) The positive rate of bacteria culture results showed no difference between bronchoalveolar lavage fluid in FFB group and tracheal secretions in the controls [43％(13/30) vs 32％(9/28), x2=0.770, P ＞ 0.05].(3) The duration of lung recruitment, antibiotic administration and hospital stay of the FFB group were all shorter than those of the control group [(4.7±3.4) vs (7.4±6.6) d, (14.0±4.5) vs (20.3±10.9) d, (15.1±4.7) vs (21.8±12.3) d, t=-5.718, 8.604 and 7.733, all P ＜ 0.05].(4) Among babies in the FFB group, nine experienced fever and returned to normal after physical cooling;three showed more shadow in chest X-ray with aggravated dyspnea during a short period, and relieved 12 hours later;two had minimal hemorrhage from tracheal mucous membrane;one showed crying hoarse.Serious complications, such as pneumothorax, massive bleeding or cardiac arrest, did not occurred.No death or refuse of treatment was reported.Conclusion FFB and BAL is much more effective than tracheal irrigation after intubation in treatment of neonatal atelectasis without any severe complications.
