Abstract
Systemic lupus erythematosus (SLE) is a systemic autoimmune disease with complicated pathogenesis and diverse clinical manifestations. The current recommendations of the Chinese Rheumatology Association are based on a comprehensive investigation of evidence based medicine, domestic and international guidelines for SLE, and experts' proposals, and aim to provide a more scientific and authoritative reference for the diagnosis and management of SLE. The recommendations focus on four aspects; clinical manifestations, laboratory evaluation, diagnosis and disease assessment, and disease treatment and monitoring. The goal of the recommendations is to standardize the diagnosis and treatment of SLE in China so as to improve the prognosis of SLE patients.

Abstract
Objective: To analyze the survival time of reported HIV/AIDS and influencing factors of Yunnan Province from 1989 to 2021. Methods: The data were extracted from the Chinese HIV/AIDS comprehensive response information management system. The retrospective cohort study was conducted. The life table method was applied to calculate the survival probability. Kaplan-Meier was used to draw survival curves in different situations. Furthermore, the Cox proportion hazard regression model was constructed to identify the factors related to survival time. Results: Of the 174 510 HIV/AIDS, the all-cause mortality density was 4.23 per 100 person-years, the median survival time was 20.00 (95%CI:19.52-20.48) years, and the cumulative survival rates in 1, 10, 20, and 30 years were 90.75%, 67.50%, 47.93% and 30.85%. Multivariate Cox proportional risk regression model results showed that the risk of death among 0-14 and 15-49 years old groups were 0.44 (95%CI: 0.34-0.56) times and 0.51 (95%CI:0.50-0.52) times of ≥50 years old groups. The risk for death among the first CD4+T lymphocytes counts (CD4) counts levels of 200-349 cells/μl, 350-500 cells/μl and ≥501 cells/μl groups were 0.52 (95%CI: 0.50-0.53) times, 0.41 (95%CI: 0.40-0.42) times and 0.35 (95%CI: 0.34-0.36) times of 0-199 cells/μl groups. The risk of death among the cases that have not received antiretroviral therapy (ART) was 11.56 (95%CI: 11.26-11.87) times. The risk for death among the cases losing to ART, stopping to ART, both losing and stopping ART was 1.66 (95%CI:1.61-1.72) times, 2.49 (95%CI:2.39-2.60) times, and 1.65 (95%CI:1.53-1.78) times of the cases on ART. Conclusions: The influencing factors for the survival time of HIV/AIDS cases were age at diagnosis in Yunnan province from 1989 to 2021. The first CD4 counts levels, antiretroviral therapy, and ART compliance. Early diagnosis, early antiretroviral therapy, and increasing ART compliance could extend the survival time of HIV/AIDS cases.

Abstract
Objective: This article investigated the clinical characteristics and distribution of drug resistance mutation sites in HBV RT region of hepatitis B infected patients. Methods: Retrospective analysis was made on 1 948 patients with HBV infection, who had been tested for NAs resistance mutation and had a medical history of NAs in the Laboratory Department of the Fifth Medical Center of the PLA General Hospital from January 2020 to December 2021. Basic clinical information and drug resistance related mutation information were recorded. Meanwhile, the serological index data of hepatitis B were collected. Drug resistance gene mutant group and non-mutated group were grouped according to whether the drug resistance genes had a mutation in HBV RT region, and the clinical characteristics and genotype distribution of the two groups were statistically analyzed. The pattern of drug resistance gene mutation, number of mutation sites, drug resistance type and mutation of NAs resistance-related sites were analyzed in 917 patients with drug resistance gene mutation in HBV RT region. χ2 Inspection was used for counting data. Meanwhile, two independent samples t-test and Wilcoxon rank sum test were used for measurement data. Results: Among the 1 948 patients with chronic HBV infection, 917 patients had drug resistance gene mutation in RT region (47.07%). The proportion of patients with acute hepatitis B and CHB in HBV RT resistance gene mutant group was lower than that in the non-mutated group, while the proportion of patients with HBV-related cirrhosis was higher than that in the non-mutated group, these differences were statistically significant. Compared with the non-mutated group in HBV RT region, the age, the positive rates of HBeAg and HBV DNA, and HBV DNA load of these patients were increased in drug resistance gene mutant group, these differences were statistically significant. Genotypes of patients in both groups were dominated by C, followed by B and D. The proportion of patients with genotype C in HBV RT drug resistance gene mutant group was higher than that of non-mutated group, the difference was statistically significant. There were 53 gene mutation patterns in 917 patients with drug resistance gene mutation in HBV RT region, and the main pattern was rtL180M+rtM204V+rtS202G (9.70%). The mutation sites were dominated by 3 (20.74%). There were 5 types of drug resistance, LAM+Ldt (21.25%) was the most. Among the 18 sites that were clearly associated with LAM, ADV, ETV and Ldt resistance in the HBV RT region, 14 sites were mutated, and the most common mutation sites were rtL180M, rtM204V, rtM204 and rtS202G. what's more, the proportion of patients with NAs drug resistance was LAM>Ldt>ETV>ADV. Conclusion: In order to prevent adverse consequences of this study such as disease recurrence or disease progression caused by HBV drug resistance, HBV infected patients, who have long-term use of NAs antiviral therapy, should monitor the level of HBV DNA and drug resistance genes in HBV RT region in order to optimize the treatment plan in time or guide individualized treatment.

Abstract
Chromium (Cr) pollution is the primary pollution problem of the soil in tannery. However, the effect of tanning chemicals on Cr migration in soil has not been clearly elucidated. Column leaching tests were designed in this study to reveal the transport and transformation of Cr from basic chromium sulfate (BCS) into soil and the effects of lime on Cr migration and transformation. The results showed that BCS was mainly leached out in the state of Cr(VI) after entering the soil, and the Cr concentration in leachate decreased with the increase of the bulking thickness of the BCS. Compared with the soil absent of lime, the concentration of total Cr in the leachate from soil with lime decreased by 8.80-88.1%. The proportions of Cr in the residual fraction were generally increased in the soil with lime, whereas other fractions were decreased. The presence of lime can reduce the migration and toxicity of BCS in soil to a certain extent. The analysis of soil bacterial community showed that the relative abundance of Proteobacteria increased significantly with the exposure to BCS and the Burkholderiaceae was the dominant bacteria family in the BCS contaminated soil. Understanding the mobility of BCS and lime and the bacterial community in BCS contaminated soil is conducive to the risk assessment of the tannery site.

Abstract
OBJECTIVE To investigate the effect of recombinant Schistosoma japonicum egg ribonuclease SjCP1412 (rSjCP1412) on proliferation, cell cycle, apoptosis and activation of human hepatic stellate cells LX-2 in vitro, and explore the underlying mechanisms. METHODS The rSjCP1412 protein was expressed in Escherichia coli BL21 by prokaryotic expression, and the highly purified soluble rSjCP1412 protein was prepared by Ni NTA affinity chromatography and urea gradient refolding dialysis. Yeast RNA was digested using 12.5, 25.0, 50.0 µg rSjCP1412 proteins at 37 °C for 2, 3, 4 h, and the enzymatic products were electrophoresed on 1.5% agarose gel to observe the RNAase activity of rSjCP1412 protein. The proliferation of LX-2 cells stimulated by different doses of rSjCP1412 protein for 48 hours was measured using CCK-8 assay, and the apoptosis of LX-2 cells stimulated by different doses of rSjCP1412 protein for 48 hours was detected using the Annexin V-FITC/PI double staining, while the percentage of LX-2 cells at G0/G1, S and G2/M phases of cell cycle following stimulation with different doses of rSjCP1412 protein for 48 h was detected by DAPI staining. The type I collagen, type III collagen and α-smooth muscle actin (α-SMA) mRNA expression was quantified using quantitative florescent real-time PCR (qPCR) assay and Western blotting at transcriptional and translational levels in LX-2 cells following stimulation with different doses of rSjCP1412 protein for 48 h, while soluble egg antigen (SEA) served a positive control and PBS without rSjCP1412 protein as a normal control in the above experiments. The expression of collagen I, α-SMA and Smad4 protein was determined using Western blotting in LX-2 cells following stimulation with rSjCP1412 protein, transforming growth factor-β1 (TGF-β1) alone or in combination, to examine the signaling for the effect of rSjCP1412 protein on LX-2 cells. RESULTS The rSjCP1412 protein was successfully expressed and the highly purified soluble rSjCP1412 protein was prepared, which had a RNase activity. Compared with the normal group, the survival rates of LX-2 cells significantly decreased post-treatment with 12.5, 25.0, 50.0 µg/mL rSjCP1412 protein and SEA for 48 h (F = 22.417 and 20.448, both P values < 0.05). The apoptotic rates of LX-2 cells significantly increased post-treatment with 12.5, 25.0, 50.0 µg/mL rSjCP1412 protein for 48 h (F = 11.350, P < 0.05), and treatment with 12.5, 25.0, 50.0 µg/mL rSjCP1412 protein for 48 h resulted in arrest of LX-2 cells in G0/G1 phase (F = 20.710, P < 0.05). Treatment with 12.5, 25.0, 50.0 µg/mL rSjCP1412 protein for 48 h caused a significant reduction in relative expression levels of collagen I (F = 11.340, P < 0.05), collagen III (F = 456.600, P < 0.05) and α-SMA mRNA (F = 23.100, P < 0.05) in LX-2 cells, and both rSjCP1412 protein and SEA treatment caused a significant reduction in collagen I (F = 1 302.000, P < 0.05), α-SMA (F = 49.750, P < 0.05) and Smad4 protein expression (F = 52.420, P < 0.05) in LX-2 cells. In addition, rSjCP1412 protein treatment inhibited collagen I (F = 66.290, P < 0.05), α-SMA (F = 31.300, P < 0.05) and Smad4 protein expression (F = 27.010, P < 0.05) in LX-2 cells activated by TGF-β1. CONCLUSIONS rSjCP1412 protein may induce apoptosis of LX-2 cells and inhibit proliferation, cell cycle and activation of LX-2 cells through down-regulating Smad4 signaling molecules.

Abstract
Urethroplasty is an important method to treat male urethral stricture. Nowadays, urethroplasty mainly includes two types: anastomotic urethroplasty and substitution urethroplasty. Anastomotic urethroplasty mainly includes primary anastomosis urethroplasty and non-transecting anastomotic urethroplasty. Substitution of urethroplasty mainly includes staged urethroplasty and one-stage urethroplasty. Substitution materials always are chosen by pedicle skin flap and free mucosal graft. Anastomosis urethroplasty has shown good results in short bulbar urethral stricture and posterior urethral stricture after pelvic fracture. Among them, non-transecting anastomosis urethroplasty has become a new surgical method for iatrogenic, single, short or non-occluded stenosis. At present, the one-stage substitution urethroplasty is the most widely used. However, there are still many complicated cases that must be solved by staged urethroplasty. Pedicle skin flap and oral mucosa are widely used as substitutes at present. How to select the best surgical procedure and substitute materials individually would be the problem worthy of attention in the future. Accumulating more long-term follow-up data is helpful for objective comparison of various surgical procedures and grafts.

Abstract
Chromium (Cr) and tannin are two major pollutants in leather industry. However, little is known about the co-migration of leather tannins and Cr in soils. In this study, column experiments were conducted to estimate Cr leaching behavior from topsoil and the environmental risk of the leachate at various tannin dosages and different ways (tannin either directly adding to the Cr-contaminated soil or adding stepwise through simulated rain) into the soil. The total Cr concentration in leachate was positively related with tannin content in soil, while Cr (Ⅵ) concentration was negatively correlated. The maximum cumulative leaching efficiency of total Cr from soil after six leaching events was 44.65% with 3 mg/g tannin adding into soil directly, and the maximum cumulative leaching efficiency of Cr (Ⅵ) was 38.75% with simulated rain leaching Cr-contaminated soil. With 3 mg/g tannin adding into soil, tannin concentration in the top layer (0-7 cm) lost by 32.67% after leaching, the amount of decomposed tannin was 0.25 mg/g, excluding the amount of tannin in leachate (3.63 mg/L) and the original amount in the soil (0.34 mg/g), indicating a slow degradation under natural condition. Both of the total Cr and Cr (Ⅵ) concentration in each layer of the soil columns decreased under tannin treatments compared with control. Compared with tannin adding stepwise into simulated rain, adding tannin into soil significantly (p < 0.05) affected the migration of Cr. Tannin increased the residual fraction while decreased the exchangeable fraction of Cr in the soils. Overall, this research can provide reference information for environmental risk assessment of contaminants in tanning sites.

Abstract
Objectives: To investigate the proportion of MSM among males over 15 years old and analyze its related factors to provide a reference for estimation of MSM size. Methods: Using cross-sectional survey design, multi-stage sampling method, and street interception survey method, a survey was conducted on males over 15 years old in Kunming from October to December 2019, with an estimated sample size of 9 908. Results: Totally, 10 707 males were recruited from 30 sites in 5 counties, and 10 283 were effectively surveyed with a response rate of 96.0%. Respondents aged 16 to 40 accounted for 75.3% (7 748), senior high school or above 71.1% (7 312), and unmarried 49.8% (5 121). The proportion of homosexual behavior in the past half-year was 1.06% (95%CI: 0.86%-1.26%), and the age-adjusted rate was 0.97% (95%CI: 0.78%-1.16%). And multivariate logistic regression showed the associated factors for homosexual behavior as following: proportion of main urban area was 2.217 times (95%CI:1.004-4.895) that of the outer suburbs, registered residence outside Kunming was 0.421 times (95%CI:0.260-0.682) that of in Kunming, having been in Kunming ≤6 months was 2.282 times (95%CI:1.262-4.126) that of >6 months, senior middle school or above was 0.336 times (95%CI:0.228-0.495) that of junior middle school and below, and being married was 0.462 times (95%CI:0.303-0.705) that of unmarried. Conclusions: The proportion of over 15-year-old males who have recently practiced male-male behavior was close to 1.00% in Kunming. The relevant factors included survey areas with a permanent residency of Kumming, short-time residency, education level, and marital status. This study obtained the data and related factors, which provided a reference for estimating MSM size in Yunnan province.

Abstract
Objective: To understand the current status of anti-hypertensive drug use in patients with hypertension in the Southwest areas of China. Methods: Based on the Program of Screening and Intervention Subjects with High Risk Cardiovascular Diseases, this study presented information on adults aged 35-75 in Southwest China by convenient sampling method, from January 2016 to November 2018. Basic information and cardiovascular related data were collected. Data on hypertensive patients were recorded, including names, doses and frequency of anti-hypertensive drugs they used. Information on the use of anti-hypertensive drugs among different hypertension subgroups, potential related characteristics, types and combination patterns of drugs, etc., were analyzed. Results: A total of 394 957 subjects were included in the study, with 159 014 identified as being hypertensive [mean age (58.8±9.5) years, 40.2% male]. 29.8% of them ever received antihypertensive drugs. A total of 30 445 of the patients reported detailed information of the drugs they ever used and 22.5% of them received therapy of combined drugs. Rates of using combination therapy were consistent among subgroups with different age, gender, blood pressure level and history of cardiovascular and cerebrovascular diseases. Results from the multivariate logistic regression analysis showed that patients with previous cardiovascular and cerebrovascular events, obesity or diabetes were more likely to have received combined therapy, while patients with less education or lower income were in the opposite. Calcium antagonists (58.6%) were the main drugs being used in single drug therapy, while traditional fixed-dose combination drugs (31.4%) were the most common ones in the drug-combination therapy, followed by angiotensin converting enzyme inhibitor/angiotensin receptor blocker combined with calcium antagonists (22.4%). Angiotensin converting enzyme inhibitor/angiotensin receptor blocker combined with beta blocker was the main drug used in patients with coronary heart disease. Conclusions: Treatment programs using the antihypertensive drugs for hypertensive patients in Southwest China needs to be improved, since the irrational use of antihypertensive drugs still exists. However, we would encourage the use of combination therapy for hypertensive patients.

Abstract
Objective: To investigate the clinicopathological features and prognosis of patients with neuroendocrine tumors (NETs). Methods: The clinicopathologic data of enrolled patients with NETs between October 2012 and October 2017 at the First Affiliated Hospital of Zhengzhou University were retrospectively analyzed. Results: Among the 488 NETs patients, the average age was (51.0±15.8) years, and the sex ratio (male/female) was 1∶1.1. Of the NETs, 370 were located in the digestive system (75.8%), 63 were pulmonary (12.9%), 14 were mediastinal (2.9%), 7 were of unknown primary origin (1.4%), and 34 were located in other sites (7.0%). Among the NETs, the pancreas, rectum and stomach were the most common sites. In the digestive system NETs, the most common tumor grade was G1 (190 cases, 51.4%), followed by G2 (143 cases, 38.6%) and NET-G3 (37 cases, 10.0%). In pulmonary NETs, typical and atypical carcinoid tumors was 47.6% and 52.4%, respectively. There were 310 patients at stage Ⅰ/Ⅱ, 53 at stage Ⅲ, 69 at stage Ⅳ and 56 at stage undiagnosed, respectively. The relationships among age, stage, grade, metastasis, treatment and prognosis were analyzed. All these factors could influence the survival rate of NET patients. Multivariate Cox analysis showed that age (>50 years old) (HR=2.831, 95%CI:1.414-7.029, P=0.025) and distant metastasis (HR=10.208, 95%CI:4.110-25.355, P<0.001) were independent risk factors. Conclusions: The most common primary sites of NETs are the pancreas, rectum, and stomach. Age and distant metastasis are independent risk factors for the prognosis of NETs.

Abstract
Objective: To understand HIV incidence in community residents and epidemiological characteristics of newly detected HIV infection cases in Dali, Yunnan province. Methods: A cohort study was conducted among 146 720 community residents who were tested to be HIV negative during 2010-2011, they were followed-up from June 1, 2014 to May 31, 2015. Results: A total of 136 356 community residents received follow up (92.9%). The follow-up time was 0.23-5.40 years (medium: 3.43 years), cumulatively 459 675 person years, and 78 people were found to be HIV positive. The incidence rate of HIV infection was 0.170/1 000 person years. The incidence rate was 0.037/1 000 person years in age group 15-29 years, 0.288/1 000 person years in age group 30-44 years, 0.210/1 000 person years in age group 45-59 years, 0.204/1 000 person years in age ≥60 years; 0.213/1 000 person years in males, 0.130/1 000 person years in females; 0.248/1 000 person years in Han ethnic group, 0.149/1 000 person years in Minorities; 0.194/1 000 in people with education level ≤ junior middle school, 0.046/1 000 person years in people with education level > junior middle school; 0.070/1 000 person years in the unmarried, 0.194/1 000 person years in the married and 0.425/1 000 person years in the divorced/widowed. Cox proportional hazards regression analysis showed that being male (HR=1.731), aged 30-44 years (HR=13.158), aged 45-59 years (HR=10.329), aged ≥60 years (HR=8.291), unmarried (HR=3.162) and divorced/widowed (HR=2.689) were the risk factors for HIV infection, while the education level > junior middle school (HR=0.132) was the protective factor for HIV infection. Conclusions: By medium 3.43 years follow up, the cohort study showed that incidence rate HIV infection was 0.170/1 000 person years in the community residents in Dali. Male, middle aged and old people, people with low education level, the unmarried and the divorced/widowed had relatively higher risk to be infected with HIV, Close attention should be paid to the prevention and control of AIDS in these populations.

Abstract
Objective: To analyze risk factors and drug resistance of community-onset methicillin-resistant staphylococcus aureus (CO-MRSA) infection through the investigation of patients infected with CO-MRSA. Methods: The clinical data of 97 cases infected with community-onset staphylococcus aureus (COSA) was collected in this hospital from July 2016 to June 2017. Epidemiological survey method and the variables were determined according to expert consultation, literature and practical work experience. Results: Among 97 patients infected with COSA, the diagnosis rate of CO-MRSA was 21.65%(21/97). The drug sensitivity results showed that: CO-MRSA was high resistant to erythromycin, tetracycline and clindamycin, and the drug resistance rate exceeded 50%. Multiple variables were analyzed by Logistic regression. The usage of antimicrobial agents in the past three months and the history of hospitalization within one year were the independent risk factors. The MRSA infection rate was 57.89%(11/19) of the persons who had taken antibacterial agents in the recent three months.The MRSA infection rate was 48.28%(14/29) of the persons who had been hospitalized in the past one year. OR value of two risk factors was respectively 10.006(95%CI: 2.200-45.519, P=0.030) and 11.519(95%CI: 2.405-55.177, P=0.002). Conclusions: Most COSA is sensitive to methicillin, but CO-MRSA is multidrug resistant and has more risk factors. The clinicians should reasonably use the antibacterial agents according to the drug sensitivity in order to prevent the occurrence of multidrug resistant MRSA.

Abstract
Objective: To understand the related risk behaviors, knowledge and status of HIV/AIDS infection among rural adults of Derung minority, to provide relevant messages for the development of HIV/AIDS intervention strategy in this minority group. Methods: We used system sampling method to conduct a cross-sectional survey in 6 administration villages of Derung Township, Gongshan Derung and Nu Autonomous County in Nujiang Lisu Autonomous Prefecture of Yunnan Province, with a sample size estimated as 383. Adult residents with Derung minority in six villages of Gongshan County were involved, with relevant information collected through door-to-door visit. HIV antibody was tested and SPSS 17.0 was used for statistical analysis. Results: Information on 394 valid respondents was collected, with age as between 18 and 65 (34.39±9.74), 80.7% (318/394) as married, 54.0% (213/394) having had primary school education, 13.2% (52/394) as migrant workers. In this population, the overall HIV infection rate appeared as 0.5% (2/400), mainly through sexually transmission. The rate of awareness on HIV/AIDS was 69.8% (275/394), mainly through free publicized materials 50.0% (197/394). Rates on premarital sexual behavior on multiple sexual partners in the past year, on temporary sexual partners in the past year, having commercial sexual experiences in the past year and ever used condoms when engaging in casual sex, were 6.4% (60/366), 18.0%(66/366), 5.7%(21/366), 1.9%(7/366) and 8.0%(25/311), respectively. Conclusions: Few numbers of HIV infections were identified among the migrating workers with Derung minority, with sexual transmission as the major route, along with the increased number of rural migrant workers and the low rates both on AIDS knowledge and condom use, accompanied by the high risk sexual behavior appeared in this rural adult residents of Derung minority. Relative strategies on HIV/AIDS intervention and control should be developed.

Abstract
Chemoresistance is a critical obstacle to the treatment of hepatocellular carcinoma (HCC). The mechanisms underlying resistance to doxorubicin, cisplatin, and 5-fluorouracil involve p53 and P-glycoprotein (P-gp). p53 plays a role in cell growth; therefore, resistance mechanisms involve chemotherapy-induced apoptosis and p53 mutation and inactivation. P-gp is an energy-dependent drug efflux pump regulated by p53. Its role in drug resistance has provided new insights into the mechanisms underlying the involvement of p53 and P-gp in chemoresistance and may alter our traditional understanding of p53 and P-gp function. This review outlines the roles and principal mechanisms of p53 and P-gp mediated chemoresistance in HCC.

Abstract
BACKGROUND This study aims to clarify the underlying mechanism for the tumor suppressive function of lnc TUSC7 in chemotherapy resistance of esophageal squamous cell carcinoma (ESCC). METHODS TUSC7, miR-224 and DESC1 expressions in ESCC tissues and cells were detected by qRT-PCR. Protein level of DESC1, EGFR and p-AKT were observed by Western blot. Overall survival was calculated using the Kaplan-Meier method. Dual-luciferase reporter gene assay and RIP assay were used to comfirm TUSC7 binding to miR-224, and miR-224 binding to DESC1. Cell proliferation, apoptosis, and colony formation was detected by MTT, Flow Cytometry and Colony formation assays. RESULTS TUSC7 was downregulated in ESCC tissues and cells, and low TUSC7 indicated worse overall survival. The analysis of bioinformatics softwares showed that TUSC7 specifically bound to miR-224, and we proved miR-224 was upregulated in ESCC and negatively correlated with TUSC7 expression. Overexpression of TUSC7/inhibition of miR-224 suppressed cell proliferation, colony formation and chemotherapy resistance of ESCC cells, and promoted cell apoptosis. In addition, we confirmed that miR-224 specifically bound to DESC1, and negatively correlated with DESC1. TUSC7 suppressed the proliferation and chemotherapy resistance of ESCC cells by increasing DESC1 expression via inhibiting miR-224. We also confirmed DESC1 inhibited chemotherapy resistance of ESCC cells via EGFR/AKT. Finally, in vivo experiments demonstrated that overexpression of TUSC7 decreased tumor growth and chemotherapy resistance. CONCLUSION These findings suggested TUSC7 suppressed chemotherapy resistance of ESCC by downregulating miR-224 to modulate DESC1/EGFR/AKT pathway.

Abstract
Osteogenesis imperfecta (OI) is a group of inherited disorders characterized by recurrent fragile fractures. Serpin peptidase inhibitor, clade F, member 1 (SERPINF1) is known to cause a distinct, extremely rare autosomal recessive form of type VI OI. Here we report, for the first time, the detection of SERPINF1 mutations in Chinese OI patients. We designed a novel targeted next-generation sequencing panel of OI-related genes to identify pathogenic mutations, which were confirmed with Sanger sequencing and by co-segregation analysis. We also investigated the phenotypes of OI patients by evaluating bone mineral density, radiological fractures, serum bone turnover markers, and pigment epithelium-derived factor (PEDF) concentration. Six patients with moderate-to-severe bone fragility, significantly low bone mineral density, and severe deformities of the extremities were recruited from five unrelated families for this study. Six pathogenic mutations in SERPINF1 gene were identified, five of which were novel: (1) a homozygous in-frame insertion in exon 3 (c.271_279dup, p.Ala91_Ser93dup); (2) compound heterozygous mutations in intron 3 (c.283 + 1G > T, splicing site) and exon 5 (c.498_499delCA, p.Arg167SerfsX35, frameshift); (3) a homozygous frameshift mutation in exon 8 (c.1202_1203delCA, p.Thr401ArgfsX); (4) compound heterozygous missense mutation (c.184G > A, p.Gly62Ser) and in-frame insertion (c.271_279dup, p.Ala91_Ser93dup) in exon 3; and (5) a heterozygous nonsense mutation in exon 4 (c.397C>T + ?, p.Gln133X + ?). Serum PEDF levels were barely detectable in almost all subjects. We identified five novel mutations in SERPINF1 and confirmed the diagnostic value of serum PEDF level for the first time in Chinese patients with the extremely rare OI type VI.

Abstract
Osteogenesis imperfecta (OI) is a group of hereditary disorders characterized by decreased bone mass and increased fracture risk. The majority of OI cases have an autosomal dominant pattern of inheritance and are usually caused by mutations in genes encoding type I collagen. OI cases of autosomal recessive inheritance are rare, and OI type XI is attributable to mutation of the FKBP10 gene. Here, we used next-generation sequencing and Sanger sequencing to detect mutations in FKBP10 and to analyze their relation to the phenotypes of OI type XI in three Chinese patients. We also evaluated the efficacy of zoledronic acid treatment in these patients. Two of the affected patients had novel compound heterozygous mutations, one patient with c.343C>T (p.R115X) in exon 2 and c.1085delC (p.A362fsX1) in exon 7, and the other patient with c.879C>G (p.Y293X) in exon 5 and c.918-3C>G in intron 5. In the third proband, we identified a homozygous single base-pair duplication, c.831dupC (p.G278RfsX95) in exon 5. In conclusion, we report for the first time that these novel pathogenic mutations of FKBP10 can lead to the extremely rare type XI OI without contractures, which expands the genotypic spectrum of OI. The phenotypes of these patients are similar to patients with types III or IV OI, and zoledronic acid is effective in increasing BMD, inhibiting bone resorption biomarkers and reducing fractures of these patients.

Abstract
OBJECTIVE To understand the status of HIV infection and risk factors among those left-behind women (LBW) in high HIV epidemic rural areas. METHODS A cross-sectional investigation was conducted between March and May, 2015 in Dehong and Lincang prefectures, Yunnan province, where HIV appeared highly epidemic. Probability Proportion to Size (PPS) sampling method was used, and 500 cases were involved and tested for HIV antibody. RESULTS The total rate of HIV infection among LBW was 8.2% (41/500). The rate of HIV infection among LBWs whose husbands were on medication was 22.7% (30/132). Data from Multi-factor logistic regression analysis showed that the risk factors of HIV infection were: being minorities, education background lower than junior high school, widowed, living in Lincang prefecture, husband infected with HIV but did not consistently use condoms,etc. The rate of HIV infection among other LBWs was 2.8% (10/363). Data from Multi-factor logistic regression analysis showed that the risk factors of HIV infection would include: aged between 30-40 years, being minorities, education background lower than junior high school, divorced, living in Dehong prefecture, having had multiple-sex partners, husband coming home less than once a year,etc. The rate of HIV infection among drug users whose husbands did not take HIV medication was 20.0% (1/5). CONCLUSION HIV prevalence among LBWs in highly HIV epidemic areas was high, and the major risk factors related to their husbands were: being drug users or with HIV infected. Further effort should be made on consistently use of anti-HIV drugs and prevention of inter-marital sexual transmission. Comprehensive intervention should be carried out for LBWs who were having lower education background, being minority and having multiple-sex partners.

Abstract
The aim of the current study was to explore mechanisms of SEMA3B gene expression and its clinical significance in glioma, and provide a theoretical foundation for investigating individualized treatment in glioma. Paraffin-embedded tissues from 43 patients with a confirmed clinical diagnosis of glioma following neurosurgery at the First Affiliated Hospital of Zhengzhou University from December 2013 to April 2014 were selected randomly. An additional three normal brain tissues were obtained following encephalic decompression excision due to acute craniocerebral injury in the same period, which were used as the control group. Immunohistochemical staining for vascular endothelial growth factor was performed on the glioma tissues from the 43 patients. Genomic DNA was extracted for bisulfate conversion and sequencing. SEMA3B was fully expressed in the three normal brain tissues, and incompletely expressed in the 43 glioma tissues, with a lack of expression in 48.8% (21/43) of samples. Moreover, 58% of high-grade gliomas (grade III and IV) lacked SEMA3B expression, which was significantly more than those that lacked expression (20%) in low-grade gliomas (grade I and II), indicating that, as the clinical pathological grade increased, SEMA3B expression decreased. The occurrence and development of malignant tumors is a product of multiple genes and other factors. Here, we provide theoretical basis for glioma development and prognosis involving DNA-methylation driven silencing of SEMA3B, and thus, SEMA3B is a potential target for directed treatments against glioma.

Abstract
Lung cancer causes the most number of deaths from cancer. Non-small cell lung cancer (NSCLC), including squamous cell carcinoma, large cell carcinoma, and adenocarcinoma, is responsible for more than 80% of primary lung cancer cases. As metastasis is the main cause of death, understanding the mechanisms underlying NSCLC metastasis are essential for improving the treatment of this disease. Recent studies have found that microRNAs (miRNAs) are involved in the progression from cell invasion and migration to final tumor metastasis of NSCLC. In this review, we will discuss the role and mechanisms of miRNAs related to the metastasis of NSCLC.

Abstract
Osteogenesis imperfecta (OI) is a group of clinically and genetically heterogeneous disorders characterized by decreased bone mass and recurrent bone fractures. Transmembrane protein 38B (TMEM38B) gene encodes trimeric intracellular cation channel type B (TRIC-B), mutations of which will lead to the rare form of autosomal recessive OI. Here we detected pathogenic gene mutations in TMEM38B and investigated its phenotypes in three children with OI from two non-consanguineous families of Chinese Han origin. The patients suffered from recurrent fractures, low bone mass, mild bone deformities and growth retardation, but did not have impaired hearing or dentinogenesis imperfecta. Next-generation sequencing and Sanger sequencing revealed a homozygous novel acceptor splice site variant (c.455-7T>G in intron 3, p.R151_G152insVL) in family 1 and a homozygous novel nonsense variant (c.507G>A in exon 4, p.W169X) in family 2. The parents of the probands were all heterozygous carriers of these mutations. We reported the phenotype and novel mutations in TMEM38B of OI for the first time in Chinese population. Our findings of the novel mutations in TMEM38B expand the pathogenic spectrum of OI and strengthen the role of TRIC-B in the pathogenesis of OI.

Abstract
AIM: To evaluate the efficacy and safety of Apatinib in advanced gastric cancer patients after failure of second-line or beyond treatment.
METHODS: From October 2014 to August 2015, 60 patients with pathologically confirmed advanced gastric cancer who failed second line or beyond treatment were enrolled in the study. All the patients were given Apatinib 850 mg/d orally until disease progression. Clinical efficacy and adverse reactions were observed. Kaplan-Meier method was used for survival analysis.
RESULTS: According to the Response Evaluation Criteria in Solid Tumors (RECIST) standard, all the patients can be evaluated for therapeutic effects. Complete response (CR) rate was 0% (0/60), partial response (PR) rate was 3.33% (2/60), stable disease (SD) rate 38.33 (23/60), and progressive disease (PD) rate 58.33% (35/60). The objective response rate (CR + PR) and the disease control rate (CR + PR + SD) were 3.33% and 38.33% (23/60), respectively. The median progression-free survival time was 3.76 mo. Patients with α-fetoprotein (AFP) positive gastric cancer had the higher disease control rate and better survival compared to the AFP negative patients. Main adverse reactions were hypertension and bone marrow suppression.
CONCLUSION: Administration of Apatinib in advanced gastric cancer patients after failure of second-line or beyond treatment is still beneficial in terms of higher disease control rate and better survival, and adverse reactions are tolerable.

Abstract
Invasion and metastasis is the major cause of tumor recurrence, difficulty for cure and low survival rate. Excavating key transcription factors, which can regulate tumor invasion and metastasis, are crucial to the development of therapeutic strategies for cancers. PU.1 is a master hematopoietic transcription factor and a vital regulator in life. Here, we report that, compared to adjacent non-cancerous tissues, expression of PU.1 mRNA in metastatic hepatocellular carcinoma (HCC), but not primary HCC, was significantly down-regulated. In addition, levels of PU.1 mRNA in metastatic hepatoma cell lines MHCC97L and MHCC97H were much lower than in non-metastatic Hep3B cells. Transwell invasion assays after PU.1 siRNA transfection showed that the invasion of hepatoma cell lines was increased markedly by PU.1 knockdown. Oppositely, overexpression of PU.1 suppressed the invasion of these cells. However, knockdown and overexpression of PU.1 did not influence proliferation. Finally, we tried to explore the potential mechanism of PU.1 suppressing hepatoma cell invasion. ChIP-qPCR analysis showed that PU.1 exhibited a high binding capacity with miR-615-5p promoter sequence. Overexpression of PU.1 caused a dramatic increase of pri-, pre- and mature miR-615-5p, as well as a marked decrease of miR-615-5p target gene IGF2. These data indicate that PU.1 inhibits invasion of human HCC through promoting miR-615-5p and suppressing IGF2. These findings improve our understanding of PU.1 regulatory roles and provided a potential target for metastatic HCC diagnosis and therapy.

Abstract
BACKGROUND The 5-year survival rate of patients with hepatocellular cancer (HCC) was very low because of invasion and metastasis in the early stage. Biomarkers might help predict early occurrence of invasion and metastasis. Accumulating evidence has shown that deleted in liver cancer-1 (DLC1) may be considered as a metastasis suppressor gene in numerous solid and hematological cancers. However, its prognostic role and mechanisms that regulate and coordinate these activities remain poorly understood. METHODS With the method of immunohistochemistry, the expression of DLC-1 as well as Rho A, ROCK2, moesin had been characterized in 80 HCC tissues and adjacent noncancerous tissues. The correlation between their expression and their relationships with clinicopathological characteristics of HCC were also investigated. In addition, the prognostic value of DLC1 expression within the tumor tissues was assessed by Cox regression and Kaplan-Meier analysis. RESULTS DLC1 expression was significantly lower in HCC tissues than in adjacent noncancerous tissues, and DLC-1 expression was found to be negatively correlated with tumor differentiation, TNM stage and lymph node metastasis. Furthermore, DLC-1 expression was found to inversely correlate with Rho A, ROCK2 and moesin which were all highly expressed in HCC tissues. Kaplan-Meier analysis showed that significantly longer 5-year survival rate was seen in HCC patients with higher DLC1 expression, compared to those with lower expression of DLC1. Multivariate Cox proportional hazard analyses revealed that DLC1 was an independent factor affecting the overall survival probability. CONCLUSION DLC1 could be served as a tumor suppressor gene in the progression especially in the invasion and metastasis of HCC. DLC1 perhaps played its role by regulating the expression of Rho A, ROCK2 and moesin. Evaluation of the expression of DLC-1 might be a good prognostic marker for patients with HCC.

Abstract
Twelve multiparous Holstein dairy cows in mid-lactation were selected for a replicated 4×4 Latin square design with a 2 ×2 factorial arrangement to investigate the effects of corn and soybean meal (SBM) types on rumen fermentation, N metabolism and lactation performance in dairy cows. Two types of corn (dry ground [DGC] and steam-flaked corn [SFC]) and two types of SBM (solvent-extracted and heat-treated SBM) with different ruminal degradation rates and extents were used to formulate four diets with the same basal ingredients. Each period lasted for 21 days, including 14 d for adaptation and 7 d for sample collection. Cows receiving SFC had a lower dry matter (DM) and total N intake than those fed DGC. However, the milk yield and milk protein yield were not influenced by the corn type, resulting in higher feed and N utilization efficiency in SFC-fed cows than those receiving DGC. Ruminal acetate concentrations was greater and total volatile fatty acids concentrations tended to be greater for cows receiving DGC relative to cows fed SFC, but milk fat content was not influenced by corn type. The SFC-fed cows had lower ruminal ammonia-N, less urea N in their blood and milk, and lower fecal N excretion than those on DGC. Compared with solvent-extracted SBM-fed cows, cows receiving heat-treated SBM had lower microbial protein yield in the rumen, but similar total tract apparent nutrient digestibility, N metabolism measurements, and productivity. Excessive supply of metabolizable protein in all diets may have caused the lack of difference in lactation performance between SBM types. Results of the present study indicated that increasing the energy degradability in the rumen could improve feed efficiency, and reduce environmental pollution.

Abstract
BACKGROUND/AIMS The metastasis of hepatic carcinoma is correlated with the body's immune status. T lymphocytes play a big part role in tumor immune. The aim of the present study is to investigate the inhibition effects of metastatsis in nude mice bearing hepatic carcinoma after T lymphocytes reconstitution. METHODOLOGY An immune reconstitution model was established in nude mice. Then, 42 nude mice were distributed into 4 groups for T lymphocytes reconstitution. The lymph nodes of each group were obtained to investigate the tumor metastasis. And the secretion of cytokines and the apoptosis of tumor cells in each group were also detected. RESULTS The ratio of CD3, CD4, CD8, CD4/CD8 in reconstituted groups were higher than controlled groups. The average time of tumor formation in Balb/c nu/nu mice was 7.7 +/- 0.6 days and in Balb/c mice was 11.5 +/- 1.3 days. After active T lymphocytes reconstitution, the extent lymph nodes metastasis in reconstitution groups was lower than control groups (p < 0.05), but proximal metastasis has no significant difference. The level of serum IL-10 in nude mice after immune reconstitution was significantly lower and VEGF was significantly higher than that of the control group (p < 0.05). Apoptosis of the hepatic carcinoma cells was increased significantly after immune reconstitution (p < 0.05). CONCLUSIONS The metastasis of hepatic carcinoma can be inhibited by reconstitution of actived T lymphocytes in nude mice, which indicated that tumor metastasis can be affected by the immune status in host body.

Abstract
Electrochemical technology with a pair of RuO(2)/Ti mesh plate electrode is first applied to pre-treat Waste Activated Sludge (WAS) prior to aerobic digestion in this study. The effects of various operating conditions were investigated including electrolysis time, electric power, current density, initial pH of sludge and sludge concentration. The study showed that the sludge reduction increased with the electrolysis time, electric power or current density, while decreased with the sludge concentration. Additionally, higher or lower pH than 7.0 was propitious to remove organic matters. The electrochemical pre-treatment removed volatile solids (VS) and volatile suspended solids (VSS) by 2.75% and 7.87%, respectively, with a WAS concentration of 12.9 g/L, electrolysis time of 30 min, electric power of 5 W and initial sludge pH of 10. In the subsequent aerobic digestion, the sludge reductions for VS and VSS after solids retention time (SRT) of 17.5 days were 34.25% and 39.59%, respectively. However, a SRT of 23.5 days was necessary to achieve equivalent reductions without electrochemical pre-treatment. Sludge analysis by Scanning Electron Microscope (SEM) images and infrared (IR) spectra indicated that electrochemical pre-treatment can rupture sludge cells, remove and solubilize intracellular substances, especially protein and polysaccharide, and consequently enhance the aerobic digestion.

Abstract
AIM: To further refine the region harboring the metastasis suppressor genes in the human chromosome 8p21.1-23.1, and to pave the way for finding and cloning novel metastasis suppressor genes.
METHODS: The STS primer sequences were found according to the National Center for Biotechnology Information Database (NCBI). C5F genomic DNA and A9/neo8 genomic DNA were used as negative and positive controls for chromosome 8 amplification, respectively. Genomic DNA was isolated and quantified from cultured hybrid clones. A9/C5F-1 and A9/C5F-2 microcell hybrid clones were used as metastasis-unsuppressed groups, while A9/C5F-4, A9/C5F-8 and A9/C5F-10 clones were used as metastasis-suppressed groups. STS-PCR products were separated by electrophoresis.
RESULTS: STS markers were preserved in metastasis-suppressed microcell hybrid clones (A9/C5F-4, A9/C5F-8 and A9/C5F-10), such as D8S552 (12786562-12786681), D8S1733(22576582-22576836), D8S1734 (22851217-22851336), D8S254(16652480-16652550) and D8S1973 (28681110-28681363) on human chromosome 8p21.1-23.1. In contrast, STS markers were lost in metastasis-unsuppressed clones (A9/C5F-1 and A9/C5F-2) in this region.
CONCLUSION: The metastasis suppressor genes may be located within the interval between D8S542 and D8S1973 on human chromosome 8p21.1-23.1.

Abstract
3D diffusion-weighted steady-state free precession imaging (3D DW-SSFP) with isotropic resolution was performed to delineate structures of the human lumbosacral plexus (LSP). 3D DW-SSFP clearly revealed detailed anatomy of the LSP and its branches. Our data suggest that the sequence based on 3D DW-SSFP can be used for high-resolution MR imaging of the peripheral nervous system.

Abstract
OBJECTIVE To evaluate the value of colonoscopy in the diagnosis of colorectal cancer. METHODS The data of colonoscopy in 1751 patients from May 2003 to June 2006 were retrospectively analyzed. RESULTS Of these 1751 colonoscopies, 643 colorectal cancers (36.7%) were detected. The age of most patients was between 40 and 60 years, and hematochezia was the major syndrome for these patients. 351 patients (54.6%) had lump type, 211 (32.8%) ulcerous type, 81 (12.6%) ulcerous infiltration type. 511 colorectal cancers (79.5%) originated from the rectum or sigmoid colon. Simultaneous double primary carcinoma was found in 15 cases (2.3%). Multiple primary cancer was observed in 2 cases. Furthermore 254 colorectal cancers (39.5%) were found to have concurrent colorectal polyps. CONCLUSION Colonoscopy of total colon and rectum is very helpful in diagnosis of colorectal cancer, which can reduce the rate of misdiagnosis and improve the survival.

Abstract
Clinical islet cell transplantation has demonstrated great promise for diabetes treatment. Two major obstacles are the organ donor shortage and the immunoresponse. The purpose of this study was to create a model using the patient's own adult stem cell sources, possibly in combination with non-self cells, such as pancreatic, hepatic, or embryonic stem cells, to create "personalized" islets. We hypothesize that the reconstructed islets have the normal capability to produce insulin and glucagon with reduced immunoresponses after transplantation. Stem cells are a proliferating population of master cells that have the ability for self-renewal and multilineage differentiation. The recently developed photolithograph-based, biologic, microelectromechanic system (BioMEMS) technique supplies a useful tool for biomedical applications. Our lab has developed a novel method that integrates the adult stem cell and BioMEMS to reconstruct personalized islets. We selected islet-derived progenitor cells (IPC) for repairing and reconstructing STZ-diabetic islets. A6(+)/PYY(+) or A6(+)/ngn3(+) cells were selected to manipulate the neoislets. After 3 to 4 weeks in culture, the reconstructed cells formed islet-like clusters containing insulin or glucagon producing cells. The pilot results showed the ability of these reconstructed islets to correct hyperglycemia when transplanted into a STZ-diabetic isograft mouse model. Although several technical problems remain with the mouse model, namely, the difficulty to collect enough islets from a single mouse because of animal size, the mouse isograft model is suitable for personalized islet development.

Abstract
The hospital is not the place for functional isolationalism, that is, for each department to do their own activities independently. Rather it is an organization in which each part is joined together and concentrating on the same objectives. The hospital must maintain a one-system-function, so that all the resources of the hospital may be used efficiently. Although we do not yet completely understand how the nursing image as perceived by the medical team and the other members of the interdisciplinary team affects nursing practice. It is important to identify how the client recognizes the nursing image as this will influence the growth of the nursing profession directly and indirectly. So we must reevaluate the nursing image as presented to the client and find the ways to present them with a better image of nursing. The study procedures were as follow: First, the image of nurses was analyzed. The subjects for this study were 270 nurses, 172 doctors, 237 hospital employees, and 240 patients and their families from 5 local branches of the Yonsei Medical Center. The four negative responses shown in this study are as follows: 1) Nurses don't listen to patients. 2) Nurses are self-centered. 3) Nurses and careless. 4) Nurses are mechanical. Second, the concrete causes of the four negative responses were analyzed. Third, the contribution of the nurses for clinical practice, research and education was analyzed. Data were collected by questionnaires all seps of the research. Data were analyzed by use of SPSS/PC+. In conclusion, the image of nurses differed according to which group, the respondents belonged. Generally, the public have a positive image of nurses, but hospital employees have a negative images of nurses. Further the nurses gave themselves a low grade. They showed negative as to the value of their job, professionality and their contribution to clinical practice when it was compared to that of the doctors.

Abstract
The ability of purified T cells to be activated by immobilized anti-CD3 and soluble anti-CD2 monoclonal antibodies (mAbs) was compared using cells from young and old donors. Purified T cells from elderly humans activated with immobilized anti-CD3 mAb incorporated less [3H]thymidine (58,780 vs 92,258 cpm; p < 0.02) into cellular DNA, and secreted less IL-2 into the culture supernatants than did T cells from young donors. In contrast, T cells activated with anti-CD2 mAbs displayed no age-related differences in proliferation or IL-2 production. Anti-CD2 stimulation resulted in equal IL-2 synthesis by cells from young and old donors that was comparable to the amount produced by cells from elderly donors stimulated with immobilized anti-CD3. Northern blot analysis of early cell cycle gene expression by anti-CD2 activated T cells demonstrated no age differences in the expression of p55 IL-2R or c-myc specific mRNA, although T cells from elderly individuals activated with immobilized anti-CD3 showed statistically significant decreases in both mRNAs. T cell receptor beta chain mRNA levels did not differ between cells from young or old donors after activation by either anti-CD3 or anti-CD2. The discordance in proliferative ability, IL-2 secretion, and specific mRNA expression between T cells from elderly donors activated through the CD3-TCR complex or by soluble anti-CD2 mAbs provides additional evidence for a multifactorial causation of age-related T cell proliferative defects, and may indicate that the difference in proliferative ability is, in part, attributable to responsiveness to secreted IL-2.

These patients were found to have lower proportions of OKT4+ subset and higher proportions of OKT8+ ratio than the healthy controls. The perturbation was more severe in patients with active disease. A significant increase of OKT 4+8+ double-labelled cells deduced by a subtraction method was also observed in the peripheral blood of patients and an inverse correlation was demonstrated between the proportions of OKT4+8+ subset and the platelet counts. Furthermore, a positive correlation between the proportions of OKT4-8+ subset and the platelet counts was also found in patients with active ITP. These data suggest that abnormalities of T cell subsets in the peripheral blood may play an important role in the pathogenesis of ITP.
