BACKGROUND:Proximal femoral nail anti-rotation has good biomechanical basis, and has obvious advantages for intertrochanteric fracture in aged patients, but there are some problems in the clinic, because of improper handling of material matching and operation details, which can impact therapeutic effects and functional recovery. OBJECTIVE:To analyze the efficacy and issues of proximal femoral nail anti-rotation in the treatment of intertrochanteric fracture in patients at more than 60 years old. METHODS:From July 2011 to July 2012, proximal femoral nail anti-rotation was used to treat 56 cases of intertrochanteric fractures. Clinical data bank was established to analyze intraopeative problems and postoperative complications. At 1, 3, 6, 9 and 12 months postoperatively, outpatient and telephone folow-up were carried out to evaluate therapeutic effects and functional recovery of hip joint. RESULTS AND CONCLUSION:Four patients died within 1 year. Seven patients lost within a year for other reasons. The remaining 45 patients were folowed with the time from 12 to 24 months, with an average time of 18.2 months. Harris score was (85.00±6.75) points. There were excelent in 26 cases, good in 15 cases, average in 3 cases and poor in 1 case, with an excelent and good rate of 91%. 18 cases were not satisfied with the position of fracture fragments. In 9 cases, proximal femur was not match with the proximal femoral nail anti-rotation. Seven cases were not satisfied because of the location and length of the spiral blade. Seven cases affected lateral cortex fracture. One case experienced postoperative pulmonary embolism. One case suffered from cardiovascular and cerebrovascular diseases. Nine cases suffered from local sweling. 13 cases experienced hip pain. Five cases affected the healing of fracture extended. Results showed that proximal femoral nail anti-rotation for intertrochanteric fracture in aged patients obtained good outcomes, but we should improve the separation of fracture fragments and reduce intraoperative and postoperative complications.

Objective To investigate the possibility of utilizing the mixed bacteria liquid and the Escherichia coli ( E.coli) liquid to establish the chronic salpingitis model of New Zealand rabbits, respectively.Methods Taken as the study object, the un-pregnant New Zealand rabbits (4~5 years old) were randomly divided into three groups: the normal group, the mixed bacteria experimental group and the E.coli experimental group.The trans-vaginal intrauterine intubation operation was performed for the injection of the mixed bacteria liquid and the E.coli liquid.Visual observation was to evaluate the gross pathological changes of the salpingitis and the pelvic cavity.HE staining and the light microscope were used to observe the micro-pathological changes of salpingitis.Results On the 15th day after modeling, increased pelvic effusion, dense peritoneal adhesion, interstitial hyperplasia and infiltration of lymphocytes were observed in both experimental groups. Conclusion Through the trans-vaginal intrauterine intubation operation, the chronic salpingitis model of New Zealand rabbits could be successfully established either by using the mixed bacteria liquid or by using the E.coli liquid.

Objective To explore the associations between coagulation factor Ⅶ (FⅦ)polymorphisms and its haplotype with risk of ischemic cerebrovascular diseases (ICVD) in Henan Han population. Methods Five hundred and twelve cases with ICVD as patient group and 560 healthy subjects as control were recruited in the study. The polymorphisms of R353Q, 5'F7 and IVS7 were detected by PCR-RFLP. The genotype frequency and allele gene frequency were compared between ICVD group and control group. The haplotype was analyzed by SHEsis software. Results The RQ genotype frequencies and Q allele frequencies of ICVD group were significantly lower than those of control group. The distribution of H7 allele frequencies and H6H7 genotype frequencies of FⅦ/IVS7 polymorphisms had significant difference between ICVD group and control group. Finally, the prevalence of R-P0-H6 haplotype in ICVD group(53. 3% )was higher than that in control group (47.5%, OR = 1. 219, 95% CI 1. 028-1. 446,P =0.023). Conclusions In Henan Han population, the Q allele of F Ⅶ/R353Q polymorphisms and the H7 allele of F Ⅶ/IVS7 polymorphisms may be protective genetic factors against ischemic cerebrovascular disease, and the R-P0-H6 haplotype may be a risk factor of ischemic cerebrovascular disease.

OBJECTIVE: To assess the effect of CPAP therapy on sleep quality and quality of life in patients with moderate or severe OSAHS. METHOD: Seventy-two patients diagnosed as OSAHS by polysomnography (PSG) were assigned to receive CPAP therapy for 3 months. At baseline and three months after treatment patients underwent polysomnography (PSG). Analyze the results of PSG, sleep quality, excessive daytime sleepiness, quality of life and the general well-being. RESULT: The lowest average oxygen saturation and the average blood oxygen saturation improved significantly after CPAP therapy, and the longest sleep apnea time and AHI decreased obviously (P < 0.01). Except body pain, the other seven dimensions of SF-36 improved obviously (P < 0.01); ESS, PSQI and GWB also improved (P < 0.05). CONCLUSION For patients with moderate or severe OSAHS, CPAP therapy can obviously improve the sleep quality, excessive daytime sleepiness, improve patients' life quality and the general well-being.

Objective: This study examined the gut bacterial communities of dogs from different breeds, all kept under identical domestication conditions. Methods: Noninvasive sampling and 16S rRNA high-throughput sequencing were used to compare the composition and function of the gut microbiota of three dog breeds: the Chinese Kunming dog (CKD), German Shepherd dog (GSD), and Belgian Malinois dog (BMD). Results: The gut microbiota of the three dog breeds consisted of 257 species across 146 genera, 60 families, 35 orders, 15 classes, and 10 phyla. The dominant bacterial phyla across the three breeds were Firmicutes (57.44%), Fusobacteriota (28.86%), and Bacteroidota (7.63%), while the dominant bacterial genera across the three breeds were Peptostreptococcus (21.08%), Fusobacterium (18.50%), Lactobacillus (12.37%), and Cetobacter (10.29%). Further analysis revealed significant differences in the intestinal flora of the three breeds at the phylum and genus levels. The intestinal flora of BMD was significantly richer than that of CKD and GSD. The functional prediction and Kyoto Encyclopedia of Genes and Genomes analysis showed that the primary functions of the gut microbiota in these breeds were similar, with significant enrichment in various metabolic pathways, including carbohydrate and amino acid metabolism, secondary metabolite biosynthesis, and microbial metabolism in different environments. The intestinal flora of these breeds also played a crucial role in genetic information processing, including transcription, translation, replication, and material transport. Conclusions and Relevance: These results provide novel insights into the intestinal flora of intervention dogs and suggest novel methods to improve their health status, which help increase microbial diversity and normalize metabolite production in diseased dogs.

Objective:To investigate the effect of high-frequency repetitive transcranial magnetic stimulation(rTMS)on cue attention in male patients with alcohol use disorder (AUD) after the acute withdrawal.Methods:A total of 90 male patients AUD who were hospitalized in the Second Affiliated Hospital of Kunming Medical University and Psychiatric Hospital of Yunnan province from May 2020 to December 2020 were enrolled, then they were divided into study group and control group using random number table.Because 18 cases fell out during the study, 36 cases were included in each of the two groups.After the alcohol withdrawal syndrome eliminated, the study group received high-frequency rTMS at 10 Hz for 14 consecutive days, and the control group was administrated by sham rTMS.At baseline and after true or sham rTMS, the cognitive psychology experiment Oddball paradigm was completed, and the behavioral data of the subjects were collected.Paired-sample t-test was used to compare the changes of the two groups before and after treatment.Data analysis were conducted using SPSS 21.0 software. Results:There was no statistical difference between the study group and the control group in terms of drinking level, cognition level and demographic data(all P>0.05). In the Oddball paradigm, compared with the control group((526.72±75.30)ms, (0.98±0.02))the reaction time((497.93±64.51)ms, t=3.145, P=0.008) and accuracy rate((0.99±0.01), t=-2.803, P=0.016) in alcohol-related cues were significantly improved in the study group after rTMS intervention, but in the control group, there were no statistical differences(both P>0.05), whether the cue was alcohol related or not. Conclusion:The results suggest that the rTMS can enhance the attention bias of alcohol-related cues and change the impulse process partly.

Objective:To explore the clinical and endoscopic features of patients with autoimmune gastritis (AIG) and to improve the accuracy of clinical diagnosis of AIG.Methods:From January 3, 2020 to November 25, 2021, the general information (gender, age), laboratory examination indicators and endoscopic findings of 179 AIG patients diagnosed at the Second Affiliated Hospital of Chongqing Medical University were retrospectively analyzed. The laboratory examination indicators included hemoglobin, gastrin-17, pepsinogen (PG), anemia combination indicators (ferritin, vitamin B 12), thyroid function indicators (thyroid-stimulating hormone, thyroglobulin antibody and thyroid peroxidase antibody), Helicobacter pylori, and anti-parietal cell antibody and anti-intrinsic factor antibody. Descriptive methods were used for statistical analysis. Results:Among the 179 AIG patients, there were 42 males (23.5%) and 137 females (76.5%), with an average age of (55.23±12.04) years old. The gastrin-17 level of AIG patients was 195.31 ng/L (143.64 ng/L, 273.61 ng/L), PG Ⅰ level and PG Ⅰ/PG Ⅱ ratio were 12.40 μg/L (7.65 μg/L, 19.40 μg/L) and 1.03 (0.66, 1.52), respectively. There were 15.3% (18/118) of the AIG patients with iron deficiency anemia, and 16.1% (19/118) with megaloblastic anemia. The positive rate of anti-parietal cell antibody was 71.8% (51/71), and the positive rate of anti-intrinsic factor antibody was 25.4% (18/71). The serum thyroid-stimulating hormone level increased in 27.3% (15/55) of the patients, and the positive rates of thyroglobulin antibody and thyroid peroxidase antibody were 31.6% (12/38) and 47.4% (18/38), respectively. The positive rate of Helicobacter pylori was 29.7% (38/128). The endoscopic appearance of AIG indicated reverse atrophy, characterized by obvious atrophy in gastric fundus and gastric body mucosa, however the atrophy of gastric antrum was not obvious. Under endoscopy yellow-white turbid mucus, which was difficult to be washed, was found in 67.0% (120/179) of the patients, and under endoscopy the residual gastric fundus glands could be seen in 19.6% (35/179) of the patients. Among 179 AIG patients, 7 cases (3.9%) of neuroendocrine tumor (NET), 7 cases (3.9%) of early gastric adenocarcinoma (including 1 case of poorly differentiated adenocarcinoma), 1 case (0.6%) of adenoma, and 14 cases (7.8%) of hyperplastic polyps were found. Except for the case of poorly differentiated adenocarcinoma undergoing surgery, the others were treated with endoscopic resection. Conclusions:When unexplained iron deficiency anemia, megaloblastic anemia, or reverse atrophy is found, AIG should be considered. AIG patients are at high risk for gastric cancer and NET, and should be closely followed up, and active treatment should be given before anemia and neurological symptoms appear.
