Objective To investigate the effects of serum brain natriuretic peptide(BNP), procalcitonin (PCT) and lung function by tiotropium bromide combined with aminophylline in the treatment of senile chronic obstructive pulmonary disease.Methods A total of 82 cases of elderly patients with chronic obstructive pulmonary disease ( COPD) were collected and randomly divided into experimental group and control group with 41 cases in each group.Patients in the control group were treated by conventional treatment; patients in the experimental group were treated on the basis of the control group with tiotropium bromide combined with aminophylline.The lung function, respiratory condition and serum levels of PCT, BNP before and after treatment were determined, and the clinical efficacy and safety was compared.Results The effective rate of the control group (68.29%) was lower than the experimental group (87.80%) , with statistical significance ( P<0.05 ); compared with the control group after treatment, the forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC) and FEV1%pre of the experimental group significantly increased, dyspnea score decreased, 4 min walking test increased, serum PCT and BNP levels decreased in the experimental group, with statistical significance ( P<0.05 ). Conclusion Tiotropium bromide combined with aminophylline in the treatment of senile chronic obstructive pulmonary disease could reduce the serum BNP and PCT levels and improve lung function.

ObjectiveTo investigate the association of HLA-Cw and -DRB1 alleles with psoriasis vulgaris,and to provide a clue to the study into the etiology of psoriasis.MethodsVenous blood samples were obtained from 81 patients with psoriasis vulgaris collected during 2006-2011 at the Department of Dermatology,First Affiliated Hospital of Inner Mongolia Medical College,as well as 100 age- and gender-matched healthy controls.Both the patients and controls are unrelated Mongolia in Inner Mongolia.PCR with sequence-specific primers(PCR-SSP) technique was used to genotype the HLA-Cw and DRB1 loci.ResultsThe patients with psoriasis vulgaris showed a significantly higher frequency of HLA-Cw*06(0.438 vs.0.175,Pc ＜ 0.01) and DRB1*07(0.241 vs.0.110,Pc ＜ 0.012),but a lower frequency of HLA-Cw*04(0.031 vs.0.150,Pc ＜ 0.01 ) and DRB1*04 (0.093 vs.0.235,Pc ＜ 0.01 ) than the healthy controls did.Increased frequencies of HLA-Cw*06 and DRB1*07 alleles were observed in patients with an onset before 40 years of age and those without a family history,together with a decreased frequency of HLA-Cw*04 and DRB1*04 alleles,compared with the healthy controls(Pc ＜ 0.05).The frequency of HLA-Cw*06 allele was significantly higher in patients with a positive family history and patients with an onset of no younger than 40 years of age than in the healthy controls (both Pc ＜ 0.05).ConclusionsHLA-Cw*06 and -DRB1*07 alleles may be susceptibility determinants to psoriasis vulgaris,while HLA-Cw*04 and -DRB1*04 alleles may be protective factors against psoriasis vulgaris,in Mongolia from Inner Mongolia.HLA-DRB1*07 allele may be a susceptibility gene for psoriasis,while HLA-Cw*04 and -DRB1*04 alleles may be protective factors against psoriasis,in patients with an onset before 40 years of age.

Objective To investigate the cause,treatment and prevention of delayed gastric emptying (DGE) after operation for esophageal carcinoma.Methods The clinical data of 13 cases with DGE after operation for esophageal carcinoma were analyzed retrospectively.Results DGE occurred at 10th day after operation.10 cases with functional delayed gastric emptying(FDGE) recovered after conservative treatmeut.3 cases with mechanical delayed gastric emptying(MDGE) were given surgical treatment.Conclusions The anatomical displacement of stomach may be the main cause of DGE.DGE is also related to vagus nerve and postoperative inadequate gastrointestinal decompression.Clinical symptoms,X-ray barium meal radiography and gastroscopy examination are the important diagnostic method.Conservative treatment should be the first choice for FDGE.The use of some gastro-intestinal prokinetic drugs may have a beneficial effect on FDGE.Once the diagnosis of MDGE is established,surgical treatment should be performed as early as possible.The fully preoperative preparation,the precise and concise techniques in operation and postoperative appropriate management may decrease the occurrence of DGE.

Objective To study the association between paternal CD3, CD4 and CD8 antigenecity to their pregnant spouses and the development of pregnancy induced hypertension (PIH). Methods Maternal serum from 15 women with PIH in the third trimester and 82 in normal pregnancies (16 in the first, 32 in the second and 34 in the third trimester) were incubated with paternal T lymphocytes. Monoclonal CD3, CD4 and CD8 fluorescent conjugated antibodies were then added and the percentage of paternal T cell differentiation antigen CD3, CD4 and CD8 were measured by flow cytometry. Results During normal pregnancy, the levels of maternal serum blocking antibodies on paternal CD3, CD4 and CD8 were (4.14?1.02, 2.02 ?0.24, 2.37?1.05)% in first trimester, (-0.29?0.13, 1.03?0.27, 0.65?0.23)% in the second trimester and (-1.33?1.47,0.15?0.01, -1.04? 0.37)% in the third trimester. There were significant difference between them( P

The aim of this study is to construct specific shRNA expressing plasmids, and to observe their effects on H9c2 cardiomyocytes injury induced by hypoxia/reoxygenation (H/R). RIPK1 and RIPK3 are the key kinases mediating the process of necroptosis. Using recombinant DNA technology, we inserted the synthetic shRNA into pSUPER vector to construct RIPK1-shRNA or RIPK3-shRNA plasmid respectively. We transfected H9c2 cardiomyocytes with the two shRNA plasmids respectively, before we treated them with H/R stimulation. Then, we measured the relevant genes and proteins by real-time PCR and Western blot. Meanwhile,we detected the markers of necroptosis and cardiomyocytes injury. The results showed that inhibition of ripk1 or ripk3 gene expression by its specific shRNA might protect the cardiomyocytes injury induced by H/R stimulation.

Objective To study the effect of skin protective membrane, semi-transparent dressing and combination of the two in critically ill patients with incontinence associated dermatitis (IAD) skin protection. Methods A total of 114 patients who were admitted into ICU and NICU of Hebei Xingtai People′s Hospital from December 2013 to November 2014 were selected. These subjects were divided into 3 groups randomly. All three groups received routine skin care, on this basis, skin protective membrane group (34 cases) used skin protective membrane for skin protection, semi-transparent dressing group (40 cases) adopted semi-permeable dressing for skin protection, while the combination group (40 cases) used skin protective membrane combined with semi-transparent dressing for skin protection. The incidence, occurrence and severity of IAD in the three groups were compared. Results The incidence rate of IAD in the combination group was 20.0%(8/40), 20.6%(7/34) in the skin protective membrane group, and significantly lower than 47.5% (19/40) in the semi-transparent dressing group, the difference was significant ( χ2=9.201, P<0.05). The occurrence time of IAD in the combination group was (4.75±0.46) days, which was significantly longer than those of the skin protective membrane group [(3.86±1.35) days] and the semi-transparent dressing group [(2.74±0.73) days], the difference was significant (F=17.120, P < 0.05). The IAD severity of the combination group scored 3.63 ±0.92, which was significantly lower than those of the skin protective membrane group (5.29±1.11) and the semi-transparent dressing group (6.74±1.79), the difference was significant (F=12.240, P<0.05). Conclusions Skin protective membrane combined with semi-transparent dressing have priority in decreasing IAD incidence rate, and delaying the occurrence time of IAD, and relieving the severity of IAD, which is better than either of the two.

The aim of this study was to observe whether necroptosis is involved in the process of cardiac hypertrophy induced by pressure overload. SD rats underwent transverse abdominal aortic constriction (TAC) operation for establishing cardiac hypertrophy model. The structure and function of the left ventricle of rats were evaluated via echocardiography, left ventricular mass index, the expression of markers of cardiac hypertrophy and histological detection. Real-time PCR and Western blot were used to measure the gene and protein expression of receptor interacting protein kinase 1 and 3 (RIPK1 and RIPK3, the necroptosis markers) respectively. Four weeks after TAC operation, rat model for cardiac hypertrophy was established. The experimental data showed that the gene and protein expressions of RIPK1 and RIPK3 in the rat heart hypertrophic tissues after TAC for 4 weeks were increased significantly compared with those in the sham group. HE staining showed cardiomyocytes injury and hypertrophy in the hearts of TAC rat models. By transmission electron microscope, we observed that mitochondria of cardiomyocytes were damaged seriously in the TAC models. Treatment with losartan used, the selective antagonist of angiotensin II type I receptor could improve the cardiac function of TAC rats. Moreover, losartan treatment decreased the expression of RIPK1 and RIPK3 in heart tissues of TAC rats. The results suggest that necroptosis occurrs in the process of cardiac hypertrophy with pressure overload, and losartan could alleviate the cardiac hypertrophy and inhibit necroptosis.

Objective To evaluate the sampling efficiency of rotary biopsy forceps in gastric precancerous lesions. Methods A total of 60 gastric lesions with suspected pre-cancerous characters under narrow band imaging were enrolled,and consecutive samples were taken from same lesion by one endoscopist with routine and rotary forceps,respectively. The most severe pathological diagnosis was regarded as the final diagnosis. Results There was a significant difference between rotary biopsy forceps and routine ones in regarding of sample quality and capability of minimize tissue damage (P＜0. 05). The concordance rate with final pathological diagnosis from sample taken by rotary biopsy forceps was higher than that from routine ones,but without significance (P＞0. 05). Conclusion The rotary biopsy forceps is superior to routine ones in sampling of gastric pre-cancerous lesions.

BACKGROUND:Early-onset scoliosis is a kind of disease that seriously affects the growth of children’s spine and development of cardiorespiratory function. The treatment of the disease has always been the focus of many clinical researchers.OBJECTIVE:To analyze the therapy for early-onset scoliosis and explore the spinal fusion, spinal non-fusion, conventional growth rod technology and magnetic control ed growth rod technology of early-onset scoliosis. METHODS:We retrieved PubMed, CENTRAL, EMbase, the ISI Web of Knowledge Databases, VIP, CNKI, CBM and Wanfang Database for related studies published from inception of the database to March 2016. The key words were“scoliosis, growing rod, complications”. The included 54 studies were analyzed and discussed. RESULTS AND CONCLUSION:For these children of early-onset scoliosis, we should not only maintain the correction of spine deformities, but also protect the ability of spine growth, keeping the normal cardiopulmonary function. In addition to conventional (non-surgical) treatment, there are surgical treatment (such as spinal fusion and growing rod technique) and magnetical y control ed growing rod, a new technology for the treatment of early-onset scoliosis. A comprehensive understanding of the effect of surgical treatment on the spine growth and cardiopulmonary function of children with early-onset scoliosis wil help to prevent the occurrence of related complications, so as to obtain a better therapeutic effect.
