Objective To explore learning burnout psychology and professional identity of nursing students studying at the traditional Chinese medicine college.Methods 200 students were surveyed by learning burnout and professional commitment scale.Results Learning burnout level of nursing students was higher,depression scores were the highest in four dimensions.Professional commitment kept within medium level.The professional identity was low.The inheritance commitment score was the lowest in each dimension analysis.Conclusions Schools and teachers should take corresponding measures to improve professional commitment level,so as to reduce learning burnout level and ensure long-term stable development of nursing profession.

Objective To investigate clinical effects of bio-feedback and pelvic electric stimulation on stress urinary incontinence (SUI).Methods Fifty-six patients with SUI were selected randomly.All the patients received one or two courses of treatment and the effects were observed.Results Forty-three patients finished the treatment and the symptoms were improved.Scores of ICI-Q-SF and rotational angle of bladder were found to be significantly different from those before the treatment.Conclusions Stress urinary incontinence could be treated by bio-feedback and pelvic electric stimulation.Both the combination of treatment and individualized treatment should be taken into account.

Drug-induced liver injury (DILI) has a complex pathogenesis and obvious individual difference. Early diagnosis and treatment of DILI may achieve good prognosis, but due to a lack of specific clinical symptoms, most cases cannot be identified in the early stage. If no timely treatment is given, DILI may progress to irreversible liver failure with a high mortality rate, and there are no effective therapies for advanced DILI except liver transplantation. Therefore, early diagnosis and treatment are of great importance for patients with DILI. This article summarizes the recent research advances in DILI, including suspected drugs, risk factors, pathogenesis, pathological features, clinical types and manifestations, diagnostic criteria and evaluation, and network database, in order to provide a basis for early diagnosis, clinical typing, treatment guidance, and prognostic evaluation of DILI.

Primary biliary cholangitis (PBC) is a chronic autoimmune liver disease characterized by progressive destruction of the small intrahepatic bile ducts. Patients with PBC often have extrahepatic autoimmune diseases, which can involve multiple organs and systems including the gastrointestinal tract, lung, rheumatoid immune system, and endocrine system. This article summarizes the research advances in the disease spectrum, pathogenesis, treatment, and prognosis of PBC with extrahepatic autoimmune disease.

BACKGROUND AND OBJECTIVEWhether gemcitabine plus platinum chemotherapy is superior to gemcitabine or platinum single-agent chemotherapy for patients with non-small cell lung cancer (NSCLC) is still in dispute, and the aim of this study is to evaluate the efficacy and safety of gemcitabine combining platinum chemotherapy for patients with NSCLC.

METHODSWe searched relevant randomized controlled trials (RCTs) from VIP, CBM, CNKI, the Cochrane library, PUBMED and EMBASE. We traced the related references and experts in this field and communicated with other authors to obtain the information that has not been found. We made quality assessment of qualified RCTs assessed by the exclusion and inclusion criteria and used RevMan 5.0 provided by the Cochrane Collaboration to perform meta-analysis.

RESULTSFour RCTs were eligible and included 984 patients. Meta analysis results suggested that: compared with gecitabine single-agent chemotherapy, the combination had a statistically significant benefit in increasing the response rate (OR = 3.29, 95% CI: 1.79-6.05, P = 0.000 1) and 2-year survival rate (OR = 3.22, 95% CI: 1.45-7.12, P = 0.004) while increased the risk of the incidence of adverse reactions, especially the grade 3-4 thrombocytopenia (RR = 8.16, 95% CI: 1.71-39.07, P = 0.009); compared with cisplatin single-agent chemotherapy, the combination had a statistically significant benefit in increasing the response rate (OR = 3.51, 95% CI: 2.20-5.60, P < 0.01) and 1-year survival rate (OR = 1.67, 95% CI: 1.16-2.41, P = 0.006) while increased the risk of the incidence of adverse reactions, especially the grade 3-4 thrombocytopenia (OR = 28.55, 95% CI: 14.06-57.04, P < 0.01).

CONCLUSIONCompared with single-agent chemotherapy, the combining can significantly improve the efficiency and survival rate while increase the toxicity rare. The results still need to be proved by high quality RCTs.

(0.05)). The sensitivity and the agreement rate were best at dose of Dob 10 ?g?kg~(-1)?min~(-1) with (86.5)% and (86.5)% (Kappa(0.71)), respectively. When Isoket combined with Dob 3,5 ?g?kg~(-1)?min~(-1), the sensitivities and the agreement rates were both significantly improved than either one used (both P

Objective:To determine the risk factors, clinical characteristics and treatment prognosis, so as to provide reference for clinicians to diagnose, treat and prevent drug-induced liver injury (DILI).Methods:Data of 712 confirmed DILI cases were collected from the Second Affiliated Hospital of Kunming Medical University between 2013 to 2019. Among them, 498 cases were included in the study. All patients medical history, clinical manifestations and classification, laboratory parameters, disease severity, and mortality rate were collected. Statistical analysis was performed using t-test, Mann-Whitney U test/Pearson χ2 test/Fisher's exact test or Spearman's rank test. Results:Among the suspicious drugs causing DILI, single medication accounted for 89.56%, mainly including traditional Chinese medicine (56.43%), anti-tumor and immunomodulatory agents (8.03%), anti-infective drugs (4.42%), antipyretic and analgesic drugs (4.22%) %), etc., while combination medication accounted for 10.44%. The clinical classification was dominated with hepatocyte injury (63.05%), and there was a statistically significant difference in clinical classification among age groups ( P<0.001). Age, alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL) and total bile acid (TBA) had statistically significant difference among different suspicious drugs in DILI caused by different drug ( P<0.001, 0.003, 0.001, <0.001 and <0.001). Laboratory test results showed that there were statistically significant differences in ALT, AST, ALP, γ-glutamyltransferase (GGT), TBA, international normalized ratio (INR), and eosinophils ( P<0.001, <0.001, <0.001, 0.018, 0.003 and 0.019, respectively). Chronic hepatitis was more common in the 54 cases who completed histopathological examination of the liver biopsy. Fibrosis degree was higher in the Western medicine group than Chinese herbal medicine group ( P<0.05), and the difference was statistically significant ( P<0.05). 96.99% of DILI patients were cured or improved, and 3.01% of patients were uncured. Ordinal logistic regression analysis showed that GGT and INR were independent predictors of poor prognosis. Conclusions:Suspicious drugs for DILI are herbal/dietary supplements, anti-tumor and immunomodulatory, anti-infective, and antipyretic and analgesic. The most common clinical classification is hepatocyte injury. Most patients with DILI have a good prognosis after drug withdrawal and GGT and INR are independent predictors of poor prognosis.

Objective Dilated cardiomyopathy (DCM) is generally considered to be accompanied by both left and right ventricular dysfunction,but most studies only analyze the left ventricular function. In this study, we evaluated the effect of arotinolol on right ventricular function in patients with DCM. Methods Right ventricular ejection fraction (RVEF) and right ventricular diameter (RVD) were measured by two-dimensional echocardiography (2-DE) in 33 DCM patients; RVEF measured by first-pass radionuclide angiography (FPRA) was compared with that by 2-DE. Results The treatment with arotinolol for one year resulted in a reduction in the right ventricular diameter (baseline, 23.0 ± 8.3 mm vs after one-year treatment, 20.7 ± 5.4 mm; P=0.004 ) and an associated increase in ejection fraction (baseline, 36.9 ± 10.3% vs after one-year treatment, 45.8 ± 9.6%; P ＜ 0.001 ); there is a high correlation between the 2-DE method and radionuclide ventriculographic method. The correlation coefficient is 0.933 (P＜0.001). Conclusion Arotinolol therapy could not only improve left ventricular function, but also improve right ventricular function in DCM patients.

Objective To detect mutations of the type Ⅱ human basic hair keratin (hHb) gene in a family of Han nationality with monilethrix.Methods Clinical data were collected from a family of Han nationality with monilethrix.Dermoscopy was performed to observe hairs of the family members,and light microscopy and scanning electron microscopy (SEM) were conducted to investigate the features of lesional hairs.Blood samples were obtained from the proband,other family members and 100 healthy controls,and DNA was extracted from these blood samples.Polymerase chain reaction (PCR) was performed to amplify the exons 1 and 7 of the hHb1,hHb3 and hHb6 genes,and DNA sequencing results were compared with their sequences in the GenBank database.Results The proband was an 8-year-old girl,whose head hairs had become fragile and easy to pull out since 2 months after birth.Skin examination showed diffuse sparsehairs,most of which were 2-cm-long broken hairs with abnormal appearance.Moniliform hairs were scattered all over the head,especially on the occipital region,and follicular keratotic papules were observed on the back of the neck.The proband was diagnosed with monilethrix.There were a total of 15 members in the 3-generation family,and 4 were diagnosed with monilethrix.The hair shafts of the 4 patients all showed typical moniliform structures.After 9-month consecutive treatment with topical minoxidil 2％ solution,the hairs of the proband turned longer and denser.A heterozygous mutation c.1237G＞A (p.E413K) was identified in the exon 7 of the hHb6 gene in the 4 patients,but not in the other family members or 100 healthy controls.Conclusion The E413K mutation of the hHb6 gene was firstly found in the patients in a Chinese Han family with monilethrix,which may be responsible for moniliform hairs.

ObjectiveTo investigate the association of the expression of the NK cell-activating receptor NKG2D, its ligand major histocompatibility complex class I chain-related gene A (MICA), and related cytokines ［interferon-γ (IFN-γ), interleukin-10 (IL-10), and interleukin-15 (IL-15)］ with intrahepatic inflammation in primary biliary cholangitis (PBC). MethodsLiver biopsy specimens were collected from 30 patients with PBC (PBC group), 15 patients with chronic hepatitis B (CHB group), and 10 patients with nonalcoholic fatty liver disease (NAFLD group), who were hospitalized in The Second Affiliated Hospital of Kunming Medical University from August 2014 to June 2015. The degree of liver inflammation (G) and fibrosis degree (S) of the liver specimens were determined, and immunohistochemistry was used to measure the expression of NKG2D, MICA, IFN-γ, IL-10, and IL-15 in liver tissue (the scores were determined based on the number of cells stained and the degree of staining to evaluate the expression of each marker). A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the t-test was used for comparison between two groups; a Spearman correlation analysis was used to investigate correlation. ResultsIn the PBC group, the expression of NKG2D increased with the degree of inflammation, and the patients with G3-4 inflammation had significantly higher expression than those with G1-2 inflammation (G1 vs G2 vs G3 vs G4: 1.4±0.05 vs 1.56±0.05 vs 1.86±0.11 vs 2.60±0.17, F=150.8, P＜0.05); the expression of NKG2D decreased with fibrosis degree (S3 vs S4: 2.30±0.17 vs 1.56±0.05, t=-1.52, P＜0.05). In the PBC group, there was no significant difference in MICA between G3 and G4 (0.11±0.01 vs 0.20±0.03, t=-2.20, P＞0.05) and between S3 and S4 (0.12±0.02 vs 0.18±0.03, t=-2.64, P＞0.05). In the PBC group, there was a significant difference in the expression of IL-15 between the patients with different degrees of inflammation (G1 vs G2 vs G3 vs G4: 0.70±0.10 vs 1.50±0.10 vs 1.93±0.11 vs 2.60±0.17, F=251.3, P＜0.05), while there was no significant difference between the patients with different fibrosis degrees (S3 vs S4: 2.00±0.05 vs 2.40±0.30, t=-1.62, P＞0.05). In the CHB group, there was a significant difference in the expression of IL-15 between the patients with different degrees of inflammation (G1 vs G2 vs G3: 0.73±0.15 vs 1.96±0.15 vs 2.50±0.17, F=150, P＜0.05) and between the patients with different fibrosis degrees (S1 vs S2 vs S3: 0.70±0.10 vs 21.96±0.15 vs 2.50±0.17, F=158.7, P＜0.05). In the PBC group, the expression of IL-10 was only observed in the patients with G1 inflammation (0.16±0.01), and in the CHB group, the expression of IL-10 was observed in the patients with G1 and G2 inflammation, with no significant difference (G1 vs G2: 0.19±0.01 vs 0.13±0.01, t=-1.522, P＞0.05). In the patients with PBC, the expression of IL-15 in liver tissue was positively correlated with the levels of alkaline phosphatase (ALP) and gamma-glutamyl transpeptidase (GGT) (r=0.241 and 0.407, P=0.014 and 0.045). ConclusionThe NK cell-activating receptor NKG2D affects the degree of intrahepatic inflammation in PBC, and the NKG2D ligand MICA is expressed in the advanced stage of PBC and can downregulate NKG2D. The expression of IL-15 increases with the degree of inflammation in PBC and is positively correlated with the levels of ALP and GGT, suggesting that the activation of NK cells and abnormal secretion of cytokines are involved in the development and progression of PBC and IL-15 may be used as an auxiliary index for the diagnosis of PBC.
