Objective To explore the factors which could lead to a preoperative diagnosis and to guide the management of cholecystoduodenal fistula (CDF).Method The experience on the diagnosis and treatment of 22 patients with CDF were retrospectively studied.These patients came from 1242 patients who received biliary tract operation in our hospital from 2001 to 2012.Results 64％ (14 of 22 patients) had 3 out of 5 of the following symptoms/signs:(1) symptoms of recurrent chills and fever,with no or only mild jaundice; (2) significant atrophy or disappearance of gallbladder on computed tomography (CT) ; (3) CT revealed complex anatomy in right upper abdomen with dilated loops of bowel; (4) ultrasound or CT revealed pneumobilia or pneumo-gallbladder; (5) barium study or duodenal endoscopy revealed obvious deformation in duodenal bulb or abnormal opening.There was no perioperative death.Morbidities included biliary fistula which presented on postoperative day 6 and day 7 in 2 patients,respectively.The daily volume of bile drainage was about 500 ml,and the biliary fistula healed after a month of conservative treatment.In addition,there were 6 patients who had infected wound,8 patients with right pleural effusion,and 8 patients with residual calculi.There was no intestinal fistula or biliary stricture.Conclusions Careful preoperative history taking and CT/uhrasound studies significantly improved the diagnostic rate of CDF.Individualized treatment reduced complications and improved clinical results.

To investigate the distribution characteristics and linkage disequilibrium of T cell immunoglobulin domain and mucin domain protein 4 (TIM4) promoter polymorphisms in asthma patients of Chinese Han population, the promoter region of TIM4 was re-sequenced by PCR-sequencing, and linkage disequilibrium was analyzed by SHEsis software. Four single nucleotide polymorphisms (SNPs) in the promoter region of TIM4 were detected, including two new SNPs (at positions-1609,-153) and two reported SNPs (rs6874202, rs6882076). The frequency distribution of rs6882076 was different among different races (P<0.05). In addition, linkage disequilibrium among the SNPs of the promoter region of TIM4 was found and GGTG was the predominant haplotype. There were four SNPs in the promoter region of TIM4 in asthma patients of Chinese Han population, which were in linkage disequilibrium.

Objective:To analyze the expression levels of miR-15 and miR-29a in serum of patients with diabetic retinopathy (DR) and their diagnostic values for DR.Methods:155 patients (155 eyes) with type 2 diabetes mellitus (DM) were treated in our hospital from June 2016 to August 2018, according to the occurrence of retinopathy and the degree of retinopathy, the patients were divided into five groups: 50 cases of non-retinopathy group (NDR group), 56 cases of simple retinopathy group (SDR group), 49 cases of proliferative retinopathy group (PDR group) and another 50 healthy persons in the same period were selected as the control group. Triglyceride (TG), total cholesterol (TC), and fasting blood glucose (FPG) were measured. Levels of serum miR-15 and miR-29a were detected by quantitative reverse transcription polymerase chain reaction (qRT-PCR). Pearson correlation method was used to analyze the relationships between levels of serum miR-15 and miR-29a with clinical indicators in DR patients. Receiver operating characteristic curve (ROC) was used to evaluate the diagnostic values of miR-15 and miR-29a in DR.Results:The relative expression of miR-15 in serum of NDR group, SDR group, and PDR group were lower than that of control group ( P<0.05), and the relative expression of miR-15 in NDR group, SDR group, and PDR group decreased gradually ( P<0.05); the relative expression of miR-29a in serum of NDR group, SDR group, and PDR group were higher than that of control group ( P<0.05), and the mRNA relative expression of miR-29a in NDR group, SDR group, and PDR group increased gradually ( P<0.05); the expression of serum miR-15 in DR patients was negatively correlated with urinary albumin/creatinine (UACR), glycosylated hemoglobin (HbA1c) and the course of DM ( r=-0.732, -0.492, -0.589, P<0.05); the expression level of miR-29a was positively correlated with UACR, HbA1c and the course of DM ( r=0.744, 0.508, 0.556, P<0.05); the areas under the ROC curve (AUC) of miR-15 and miR-29a for DR diagnosis were 0.796 (95% CI: 0.724-0.857) and 0.677 (95% CI: 0.597-0.749), with diagnostic thresholds 0.63 and 1.11, sensitivities 84.9% and 53.8%, specificities 65.3% and 79.6%, repectively; miR-29a was a risk factor for DR, while miR-15 was a protective factor for DR. Conclusions:The expression of mir-15 and miR-29a in the serum of DR patients is decreased, which is related to the degree of retinopathy and can be used as biomarkers for early diagnosis of DR.

Objective To study the homology characteristics of clinicaly isolated and colonized linezolid(LZD)-resistant Enterococcus faecalis (E.faecalis) strains from a patient.Methods Ten E.faecalis strains (2 were isolated from urine specimens and 8 were from stool specimens) isolated from a patient with pulmonary infection were performed antimicrobial susceptibility testing, homology of E.faecalis was determined by pulsed-field gel electrophoresis (PFGE).Results Before and after patients received LZD therapy, 2 E.faecalis strains isolated form urine specimens were both resistant to LZD (MICs: 8 mg/mL, 16 mg/mL, respectively), among 8 strains from stool specimens (6 were isolated before therapy, and 2 were isolated after therapy), LZD susceptible, intermediate, and resistant strains were 4, 2, and 2 respectively(MICs: 0.25-12 mg/mL).10 strains of E.faecalis were homologous by PFGE typing.Conclusion In this case, the detection of E.faecalis from urinary tract and intestinal tract is homologous, which suggested that LZD-resistant Enterococcus may be colonized in vivo for a long time, and may be shift to cause bacterial infection.

Acceleration of tooth movement during orthodontic treatment is challenging,with osteoclast-mediated bone resorption on the compressive side being the rate-limiting step.Recent studies have demonstrated that mechanoreceptors on the surface of monocytes/macrophages,especially adhesion G protein-coupled receptors(aGPCRs),play important roles in force sensing.However,its role in the regulation of osteoclast differentiation remains unclear.Herein,through single-cell analysis,we revealed that CD97,a novel mechanosensitive aGPCR,was expressed in macrophages.Compression upregulated CD97 expression and inhibited osteoclast differentiation;while knockdown of CD97 partially rescued osteoclast differentiation.It suggests that CD97 may be an important mechanosensitive receptor during osteoclast differentiation.RNA sequencing analysis showed that the Rap1a/ERK signalling pathway mediates the effects of CD97 on osteoclast differentiation under compression.Consistently,we clarified that administration of the Rap1a inhibitor GGTI298 increased osteoclast activity,thereby accelerating tooth movement.In conclusion,our results indicate that CD97 suppresses osteoclast differentiation through the Rap1a/ERK signalling pathway under orthodontic compressive force.
