Objective To investigate the correlation between single nucleotide polymorphisms (SNP) of gene interleukin-23 receptor (IL-23R) rs1004819, rs1495965, rs1884444, rs2201841,rs6677188, rs7517847, rs7530511, rs10489629, rs10889677 and rs11209026 with susceptibility of inflammatory bowel disease (IBD) in Han population of Jiangsu province in China. Methods The gene polymorphism in 134 healthy volunteers, 135 cases of ulcerative colitis(UC) and 43 cases of Crohn's disease(CD) were detected with SNaPshot. Experimental data were analyzed with SPSS 17.0 software. Results In UC, genotype frequency of CC and CT on rs7530511 was 99.26％ (134/135)and 0.74％(1/135), allele frequency of C and T was 99.63％(269/270)and 0. 37％(1/270). While in normal controls, which were 94.03％(126/134), 5.97％(8/134), 97.01 ％(260/268)and 2.99％(8/268)respectively. Compared genotype frequency of these two group, P value was 0. 040 (OR＝0.118、95％CI:0.014～0.953). Compared allele frequency of these two group, P value was 0. 043 (OR＝0.121、95％CI:0.015～0.973). In wild type and mutation type UC patients, the age distribution was different, more young patients in mutation type while more middle-aged patients in wild type, P value was 0.032 and 0.001 respectively. Most UC patients of rs6677188 AT type were in remission under endoscope (P＝0.032). Conclusion The mutation of IL-23R rs7530511 may be a protective factor of UC. The polymorphism of rs6677188 was associated with the age of patients and the remission under endoscope.

This study is to examine the effects of NNIspm-mediated cellular senescence of HepG2 cells and elucidate its potential molecular mechanism. Cellular senescence was detected with senescence-associated beta-galactosidase staining. Cell cycle distribution, intracellular fluorescence intensity and accumulation of intracellular reactive oxygen species (ROS) were detected by high content screening (HCS). Protein expression was detected by Western blotting. Polyamines content was analyzed by high performance liquid chromatography (HPLC). The results demonstrated that NNIspm significantly induced HepG2 cells senescence. This effect was due to the decrease of intracellular polyamines, the arrest at G0/G1 phase and an increase of ROS level. The molecular senescence marker p21 increased significantly after NNIspm treatment. In contrast, the protein expressions of Cyclin E and CDK2 were obvious down-regulation. The results indicated that cellular senescence induced by NNIspm was one of its antitumor mechanisms.

Objective To study the diagnosis, treatment and prognosis of the rupture of breast implant. Methods Physical examination, X-ray fluoroscopy, high frequency and color the Doppler ultrasonography were helpful to make a clear diagnosis, in exploring and removing the fiber envelope by inframammary or periareolar incision, repairing the anatomy structure of the breasts and performing augmentation mammaplasty again. Results In 32 patients, the breast shape was basically symmetrical, most of the incisions were healed by first intention except 2 cases with complication of subcutaneous fluid collection. A satisfactory therapeautic result could be achieved by taking out the breast implant which was rupture, exploring and removing the fiber envelope, and extending the lacuna. Conclusion A satisfactory therapeautic result can be achieved by extending the lacuna.

Primary tracheobronchial amyloidosis (TBA) is a rare pulmonary disease. A systematic review was performed on 64 cases of primary TBA in China and progress in the diagnosis and treatment of this disease is discussed. The Chinese biological and medical databases from 1970 to 2010 were searched and 75 cases of complete clinical and pathological data were identified. The clinical characteristics of the disease were summarized and longitudinal comparisons were made of diagnostic and treatment methods over time. The results showed that the morbidity associated with primary TBA has increased over recent years. The clinical manifestations were non-specific. Progressive dyspnea, cough and sputum were the most common symptoms. The percentage of patients undergoing computed tomography (CT) scan has increased over the years. The bronchoscopy and transbrochial lung biopsy (TBLB) were usually sufficient to establish the diagnosis. Treatment was reported for a total of 44 cases. Bronchoscopic Nd:YAG laser irradiation, argon plasma coagulation (APC) and drugs administration such as steroids and colchicines were reported to be effective in some patients. It is concluded that the demographic characteristics and clinical manifestations of primary TBA patients in China are largely consistent with findings reported in other countries. Dramatically more cases were reported in recent years, mainly due to the extensive application of bronchoscopy since 1990s. Chest CT scan provides important clues for the diagnosis of the disease. The definite diagnosis was confirmed by bronchoscopic findings and Congo red staining of biopsy specimen. Bronchoscopic Nd:YAG laser irradiation, argon plasma coagulation (APC) and drugs administration, such as steroids and colchicines were reported to be effective in some patients.

Objective To discuss necessity of cholecystectomy for patients with stones in their bile ducts and gallbladders in the absence of absolute operation indications of cholecystectomy after clearance of bile duct stones with ERCP. Methods Data of less than 70-year-old patients with stones in their bile ducts and gallbladders but without absolute operation indications of cholecystectomy admitted to the First People′s Hospital of Hangzhou from January 2012 to December 2014 were retrospectively analyzed. Patients were divided into cholecystectomy group and gallbladders in situ group after bile duct stones removal with ERCP. The hospitalization time, recurrent biliary events, complications of operation were compared between two groups. Results A total of 128 patients were included and followed up for(24.031±9.170)months with 64 cases in conservative group and 64 cases in cholecystectomy group. Incidence of recurrent biliary events in the cholecystectomy group and conservative group were 7.8%(5/64)and 10.9%(7/64)(P=0.544). Among cases of recurrent biliary events,incidences of cholangitis in the two groups were 7.8%(5/64)and 4.7%(3/64)respectively(P= 0.465), incidences of pancreatitis were 0(0/64)and 1.6%(1/64) respectively(P=0.315), incidences of common bile duct stones were 7.8%(5/64)and 7.8%(5/64)respectively(P = 1). No recurrent cholecystitis occurred. There were no differences in ERCP-related complications between the cholecystectomy group[23.4%(15/64)]and the conservative group[12.5%(8/64)](P=0.107). But 4 patients(6.3%)in cholecystectomy group had LC-related complications during the follow-up period, 3 cases of infection and 1 ileus. The hospital stay in conservative group was shorter than that in cholecystectomy group(5.906± 4.614 days VS 14.313± 6.312 days, P<0.001). The hospitalization expenses in two groups were(45 196± 12 518)yuan and(22 160± 11 755)yuan(P<0.001). Conclusion Conservative methods yield to shorter hospitalization and lower expenses without cholecystectomy-related complications. Conservative management for gallbladder stones after ERCP for biliary duct stones is recommended for patients who had no absolute operation indications of cholecystectomy.

Objective:To investigate the current situation of cytomegalovirus (CMV) infection in infants in Lishui, and summarize the related factors of CMV infection, evaluate its influence on the growth and development of infants, and provide evidence for the prevention and control of CMV infection.Methods:In this study, 2 254 cases of infants admitted in pediatric ward in Lishui Maternal and Child Health Hospital, Qingtian County People′s Hospital, Suichang County People′s Hospital, Qingyuan County People′s Hospital from January 1, 2015 to December 31, 2017 with integral clinical data were selected. All the babies were followed up from the time when they were born to 1 year old. The serum CMV antibody and the urine CMV-DNA were screened, the general situation and clinical features of CMV infection were summarized, and the relevant factors of infants CMV infection were analyzed and screened by the single factor and multiple factors analysis. They were followed up to 1 year old to clarify the influence of CMV infection on the growth and development of infants.Results:From 2015 to 2017, the total positive infection rate of CMV-IgM in infants under 1 year old in Lishui was 10.43%(235/2 254), and CMV-IgM positive infection decreased year by year. The positive rate of CMV-IgG did not change significantly with time. The positive rate of CMV-IgM was the highest at 1—3 months, and up to 15.29% (61/399). The positive rate of CMV-IgM decreased with the age of the babies. The positive rate of CMV-IgG increased with the age of the babies. The positive rate of CMV-IgM in infants showed no significant difference in gender ( P>0.05). The positive rate of CMV-IgM was higher in men than that in women [65.43% (810/1 238) vs. 55.51% (564/1 016)], and there was significant difference ( P<0.05). The gestational age of the infected group was lower than that of the non-infected group [(37.41 ± 1.63) weeks vs. (38.97 ± 0.97) weeks], and the breast-feeding rate of the infected group was higher than that of the non-infected group [57.87%(136/235) vs. 40.00%(40/100)], and there were significant differences ( P<0.05). Thrombocytopenia, the increase of transaminase, necrotizing enterocolitis of newborn, and hepatosplenomegaly of infected group is higher that of the non-infected group [18.72%(44/235) vs. 1.00% (1/100), 29.36% (69/235) vs. 13.00% (13/100), 26.81% (63/235) vs. 10.00% (10/100), 9.79% (23/235) vs. 0], and there were significant differences ( P<0.05). Gestational age and breast-feeding were possible risk factors for CMV infection in infants under 1 year old ( P<0.05). There was no significant difference in height, weight, head circumference and intelligence score between the infected group and the non-infected group at the age of 1 year ( P>0.05). The total abnormal rate of hearing development and the abnormal detection rate of B-ultrasound in the infected group were higher than those in the non-infected group [13.62%(64/470) vs. 1.00%(2/200), 6.38%(15/235) vs. 0], and there were significant differences ( P<0.05). Conclusions:The CMV active infection rate of infants under 1 year old in Lishui is relatively high and decreases year by year. It decreases with the prolongation of birth time, and there is no gender difference. Gestational age and breast-feeding are the risk factors for active CMV infection in infants. CMV infection affects the hearing development and the brain development of infants under 1 year old, which is the main cause of hepatitis. It is necessary to pay attention to the prevention of CMV infection, strengthen maternal perinatal health care, and strengthen the screening of CMV infection in high-risk groups.
