Objective: To investigate the objective characteristics of tongue manifestation in different stages of damp-heat syndrome in diabetic kidney disease (DKD). Methods: A cross-sectional study enrolled 134 patients with DKD G3-5 stages who met the diagnostic criteria for damp-heat syndrome in DKD. The patients were treated at Dongzhimen Hospital, Beijing University of Chinese Medicine, from May 2023 to January 2024. The patients were divided into three groups: DKD G3, DKD G4, and DKD G5 stage, with 53, 33, and 48 patients in each group, respectively. Clinical general data (gender, age, and body mass index) and damp-heat syndrome scores were collected from the patients. The YZAI-02 traditional Chinese medicine (TCM) AI Tongue Image Acquisition Device was used to capture tongue images from these patients. The accompanying AI Open Platform for TCM Tongue Diagnosis of the device was used to analyze and extract tongue manifestation features, including objective data on tongue color, tongue quality, coating color, and coating texture. Clinical data and objective tongue manifestation characteristics were compared among patients with DKD G3-5 based on their DKD damp-heat syndrome status. Results: No statistically significant difference in gender or body mass index was observed among the three patient groups. The DKD G3 stage group had the highest age (P<0.05). The DKD G3 stage group had a lower score for symptoms of poor appetite and anorexia(P<0.05) than the DKD G5 group. No statistically significant difference was observed in damp-heat syndrome scores among the three groups. Compared with the DKD G5 stage group, the DKD G3 stage group showed a decreased proportion of pale color at the tip and edges of the tongue (P<0.05). The DKD G4 stage group exhibited an increased proportion of crimson at the root of the tongue, a decreased proportion of thick white tongue coating at the root, a decreased proportion of pale color at the tip and edges of the tongue, an increased hue value (indicating color tone) of the tongue color in the middle, an increased brightness value (indicating color lightness) of the tongue coating color in the middle, and an increased thickness of the tongue coating (P<0.05). No statistically significant difference was observed in other tongue color proportions, color chroma values, body characteristics, coating color proportions, coating color chroma values, and coating texture characteristics among the three groups. Conclusion Tongue features differ in different stages of DKD damp-heat syndrome in multiple dimensions, enabling the inference that during the DKD G5 stage, the degree of qi and blood deficiency in the kidneys, heart, lungs, liver, gallbladder, spleen, and stomach is prominent. Dampness is more likely to accumulate in the lower jiao, particularly in the kidneys, whereas heat evil in the spleen and stomach is the most severe. These insights provide novel ideas for the clinical treatment of DKD.

Objective:To investigates the clinical efficacy of the trabecular metal acetabular revision system (TMARS) in one-stage reconstruction of acetabular deficiencies associated with periprosthetic joint infection (PJI).Methods:This is a retrospective case series study,including the data of 59 patients with PJI underwent acetabular defect reconstruction by TMARS during one-stage revisions in the Department of Orthopaedics, the First Affiliated Hospital of Xinjiang Medical University from January 2013 to December 2021. There were 32 males and 27 females, aged (59.5±14.6) years (range: 26 to 84 years). Among them, 29 cases used tantalum cups, 13 cases used tantalum cups and tantalum reinforcing blocks, 9 cases used cup-cage, and 8 cases used multi-cup reconstruction techniques. The surgery procedure, Harris Hip score (HHS), recovery of the hip rotation center, implant survival rate, postoperative reinfection rate, and complications were recorded. Data were compared using the Wilcoxon rank-sum test.Results:All of the 59 patients underwent the operations successfully. Operation time was (188.9±48.4) minutes (range: 110 to 340 minutes), and intraoperative bleeding volume was ( M(IQR)) 1 000(400)ml (range: 600 to 1 800 ml). After a postoperative follow-up of 5.1 (2.6) years (range: 2.0 to 10.5 years), the prosthesis survival rate was 94.9% (56/59). Recurrence of infection occurred in 3 cases (5.1%), aseptic loosening in 1case(1.7%), and hip dislocation in 4 cases (6.8%). At the last follow-up, HHS improved significantly(84 (12) vs. 44 (9), Z=-6.671, P<0.01), and the center of rotation of the hips were recovered in all cases. Conclusions:In one-stage revision surgeries aimed at reconstructing acetabular defects, utilizing the TMARS can provide stable initial fixation, restore a more natural center of rotation, significantly enhance early postoperative hip joint function, and reduce the likelihood of infection recurrence. This approach stands as a reliable choice for addressing acetabular defects during revision surgeries for infected hip joints.

ObjectiveTo explore the relationship between smoking behavior and related factors among the adult residents in Fengxian District,so as to provide an evidence for carrying out tobacco control and other health promotion work. MethodsA multi-stage stratified cluster random sampling method was used to select 2 272 community residents aged between 15 and 69 yeas to carry out the questionnaire survey. ResultsIn 2020, the smoking rate of adult residents in Fengxian District was 23.50%. Smoking behavior was statistically correlated with age, gender, household registration, chronic disease, occupation and educational level. Smoking behavior was inversely correlated with educational level. Smoking rate of male residents was significantly higher than that of female residents, smoking rate of residents with chronic diseases was significantly higher than that of those without suffering from chronic diseases, and smoking rate of permanent registered residents was significantly higher than that of those non-locals. The highest smoking prevalence was among retired and freelancers, followed by staff of government agencies and public institutes, while the lowest was among students, followed by intellectuals. Multivariate logistic regression analysis showed that gender, age and education level were the main factors affecting the smoking prevalence level. ConclusionThe general　smoking rate of adult residents in Fengxian District was higher than the average level in Shanghai but lower than the national level. Male residents aged ≥25 years and with lower education level are the key invention targets for tobacco control.

OBJECTIVETo obtain very end full-length cDNA of hepatitis C virus (HCV) 5' untranslated region (5' UTR), and analyse its primary and secondary structure.

METHODSBy reverse transcription-nested polymerase chain reaction (RT-PCR) and restriction fragment length polymorphism (RFLP), a patient infected with genotype 2a HCV was found. Total RNA isolated from the serum as template, the cDNA of 5' noncoding region was amplified using rapid amplification of cDNA ends methods (RACE), the fragments were recombined by A-T clone strategy, the recombinants were confirmed by RFLP and PCR then sequenced. Secondary structures were analysed by RNA draw.

RESULTSVery end full-length cDNA of 2a genotype HCV 5' UTR was obtained by RACE. In five clones obtained, three contained full-length 5' UTR cDNA, and A21G, G170A, T222C, T247C, C339T substitutions were found compared with HC-J6. he homologies with HCV-1,HC-J6,HC-C2, HC-J8 were 93.6%-94.4%, 92.1%-93.0%, 98.8%-99.7%, 96.2%-96.5%, respectively; however, the substitutions did not alter the secondary structure. Two out of five clones were deleted to have 53 and 144 bases at 5' terminus of HCV 5' UTR, respectively.

CONCLUSIONSRACE is rapid and effective, works well to obtain very end of virus genome. With that, Authors obtained full-length cDNA of genotype 2a of HCV 5' UTR. There are genes deleted at 5' terminus circulated in hepatitis C patients.

OBJECTIVETo study the relationship between polymorphism of inducible Nitric Oxide Synthase (iNOS) gene and the susceptibility of intestinal type stomach cancer and stomach cardia cancer in Chinese people.

METHODSA community-based case-control study was designed. Ninety-three intestinal type of stomach cancer and 50 stomach cardia cancer patients with endoscopy and pathology diagnosis were identified as cases. Two hundred and forty-six controls served as controls.

RESULTSC-->T polymorphism was found in exon 16 of iNOS gene, which changed the coding amino acid from serine to leucine, and formed a recognition site identified by Tsp 509 I restriction enzyme (we called it C-->T polymorphism). The T allele gene frequency in the control group was 13.21%. No statistically significant difference was found between C-->T polymorphism alone and the increased susceptibility to intestinal stomach cancer or stomach cardia cancer. A significant type 2 multiplicative interaction was found in increasing both the risk of intestinal stomach cancer and stomach cardia cancer when both C-->T polymorphism and tobacco smoking exposure existed. An additive interaction model, which showed statistically significant difference, was found to increase only the risk of stomach cardia cancer when CagA antibody shared negative but C-->T polymorphism occurred.

CONCLUSIONC-->T polymorphism of iNOS gene was considered as one of the possible susceptible genes, which specifically increased the risk of tobacco-related but CagA negative types of intestinal stomach cancer and stomach cardia cancer.

OBJECTIVETo find out the distributive features of some metabolic genes polymorphisms in Han population of south area of China.

METHODSStudy population was obtained from the controls of a community based case-control study, which included 290 blood relatives (inner control) and 404 non-blood relatives (outer control).

RESULTSFrequencies of CYP1A1, GSTM1 and GSTT1 polymorphisms had no significant difference among confounding factors, such as sex, living areas, stomach cancer family history and history of tobacco smoking etc. Some controls showed significant difference in age group and alcohol drinking which would be adjusted in analysis of the relationship between polymorphisms and cancers. CYP1A1 Ile/Val and Val/Val genotypes were 33.43% and 5.62% respectively, which were similar to other results from Chinese and Japanese, but higher than those from Caucasians in American, Europe and African-Americans. GSTM1 null allele frequency was 53.48% in our population, which showed difference even among Chinese in different areas. GSTT1 null allele frequency was 45.78%, which was significantly higher than that in Caucasians and African-American.

CONCLUSIONThe frequencies of CYP1A1 Ile/Val, Val/Val and GSTT1 null in Han population in south area of China are significantly higher than those in other races, while the ethnic difference of frequency of GSTM1 null is less.
