Objective To systematically review the effectiveness and safety of statins for chronic obstructive pulmonary diseases (COPD) combining with pulmonary hypertension (PH).Methods The electronic searches in databases of PubMed,EMbase,the Cochrane Library,Web of Science,CBM,CNKI,VIP and Wanfang Data were conducted from the date of their establishment to January 2016 and the references of the include studies were also retrieved for collecting randomized controlled trials (RCTs) or quasi-RCTs on statins treating COPD combining with PH.Two researchers independenlty screened the literature according to the inclusion and exclusion criteria,extracted the data,assessed the quality of the included studies by adopting the Cochrane collaboration' s tool for assessing risk of bias,and performed Meta-analysis by using RevMan 5.3 software.Results A total of 24 studies involving 1 587 cases were included.The results of Meta-analysis showed that:compared with the control group,simvastatin significantly improved FEV1 [MD =0.23,95％ CI:0.16-0.31,P ＜ 0.000 01],FEV1 ％ [MD =6.73,95％ CI:1.34-12.12,P =0.01],FVC [MD =0.39,95％ CI:0.34-0.45,P ＜ 0.000 01],6 minutes walk distance (6MWD)· [MD=59.09,95％CI:54.24-63.93,P ＜0.000 01] and decreased mPAP [MD=6.73,95％ CI:1.34-12.12,P =0.01],SPAP [MD =-4.53,95 ％ CI =-8.87--0.19,P =0.04].Atorvastatin significantly improved FEV1 [MD =6.22,95 ％ CI:2.51-9.93,P =0.001] and 6 MWD [MD =24.10,95 ％ CI:12.98-35.23,P ＜ 0.000 1] and decreased sPAP [MD =-6.44,95％CI:-7.95--4.93,P＜0.00001] andmPAP [MD=-3.51,95％CI:-5.81--1.22,P=0.003].But no significant difference was found in the improvement of FEV1,FVC or FEV1/FVC.Fluvastatin significantly decreased sPAP [MD=-5.89,95％ CI:-6.99--4.79,P ＜0.000 01].There was a significant decrease in the Borg dyspnoea score in statins group [MD =-3.37,95％ CI:-4.61--2.14,P ＜ 0.000 01] as compared with the controls.In addition,the incidence of adverse drug reactions (ADRs) was similar between statins and the control group.Conclusion Current evidence suggests that statins may decrease pulmonary hypertension in patients with COPD combining with PH.However,high-quality clinical trials with large sample size are needed to verify whether the improvement of pulmonary function,6MWD and Borg dyspnoea score are the class effect or the incidence of ADRs is disparate among different statins.

Objective To explore the relationship between life events and depression of patients with primary sjgren's syndrome (PSS).Methods 80 patients with PSS complicating depressive disorder were tested by self-rating depression scale(SDS) and life event scale (LES),and compared with the control group including 80 PSS patients with non-depressive disorder matched with age and sex.Then the correlation between SDS and LES were analyzed.Results The total score of life events (32.72 ± 13.93),the score of negative life events (24.36 ±11.24),the score of SDS(58.60 ± 16.78) and the frequency of life events(91.3％) in the research group were higher than those in control group(P ＜ 0.05),but the positive life events score (7.15 ± 5.84) was lower than that in control group (9.76 ± 7.29),and there was statistically significant difference between the two groups (P ＜ 0.05),there were more negative life events,especially on the aspects of family,work and study in the research group.There was positive correlation among the negative life events score,total score of life events and SDS score in the research group(P＜ 0.01),meanwhile,negative correlation was revealed between the score of positive life events and SDS score in the research group(P ＜ 0.05).Conclusion Patients with PSS complicating depressive disorder experienced more negative life events which play an important role in depression of patients with PSS.

Objective To survey the prevalence and the related factors of depression in patients with primary Sj(o)gren's syndrome (pSS),and provide references for early mental intervention.Methods The depression state of 217 patients with pSS was screened with self-rating depression scale (SDS) first and then assessed by Hamilton depression scale (HAMD,17 index).The prevalence of depression was determined based on the diagnosis of psychiatrist based on the 3rd edition of Chinese classification of mental disorders (CCMD Ⅲ).The personality was evaluated by Eysenck personality questionnaire (EPQ),and the life events were questionnaired by life events scale (LES).The general condition was analyzed by self-designed questionnaire.Finally,step-wise multiple factor regression analysis was carried out to determine the risk factors that best accounted for the depression.Results The prevalence rate of depression in patients with pSS was 39.2％ (85/217).There were 5 factors entered the regression equation by multifactor regression analysis.They were severe pain,concerns of doctor and nurse,known of the fact by patients,adverse life events,and neuroticism of EPQ,and the concern of doctor and nurse was negatively correlated.Conclusion More attention from clinicians should be paid to the depression of pSS.Patients with severe pain,lack of attention from doctors and nurses,known of the disease itself,adverse life events and neurotic personality traits are factors related with depression.Recognizing the risk factors early can provide guidance for early psychological intervention.

Objective To understand the epidemiological and etiological characteristics of influenza in Mianyang City from 2019 to 2021, so as to provide a basis for the prevention and control of influenza. Methods Influenza surveillance data in Mianyang City from 2019 to 2021 were collected and analyzed statistically. Results A total of 55 970 cases of influenza were reported in Mianyang City from 2019 to 2021, with an average annual incidence of 388.08/100 000. A total of 103 723 cases of influenza -like illness cases (ILI) were reported, with an average annual ILI% of 3.58%. The incidence, ILI% , and positive detection rates of influenza were all far higher than those in the corresponding period in 2019. The classification of the population is mainly composed of students under the age of 15. The top three reported cases were Fucheng District (20 118, 35.94%), Youxian District (6 394, 11.42%) and Jiangyou District (5 800, 10.36%). 10 126 samples of ILI were received and detected, with a positive rate of 19.53%, the positive rate of ILI samples was mainly students under 15 years old. The dominant strains of influenza viruses showed an alternating trend over the years, and A (H3) was the predominant type in 2019. Except for 2 A (H9) strains detected in 2021, the rest were all BV strains. Due to the impact of COVID-19 in 2020, the positive detection rate was low throughout the year. 43 outbreaks of ILI were reported, which were mainly occurred in winter, and most of them were in primary schools. Conclusion From 2019 to 2021, the characteristics of cases, ILI, pathogen surveillance and outbreak events of influenza in Mianyang City are basically the same, with students under 15 years of age and schools remaining the key population and sites of concern. the importance of non-pharmaceutical interventions for influenza prevention and control is further evidenced by the low incidence of influenza during the COVID-19 pandemic.

Objective To analyze the characteristics of proximal deep vein thrombosis (DVT) after total joint arthroplasty.Methods 40 cases of proximal DVT were collected from May 2007 to October 2016 which were all diagnosed by lower limb venography or sonography.There were 9 males and 31 females aged from 38 to 86 years,average 67 years,and body mass index was from 16.94 to 31.25kg/m2,with an average of 24.3 kg/m2.29 cases of THA patients and 11 cases of TKA patients.The anatomical distribution,size,radiological performance,local physical findings were recorded and multivariable analysis was performed to evaluate the relationship between distribution of proximal DVT and related parameters including age,gender (male/female),side of leg(left/right),surgery type(knee and hip),preoperative diagnosis(femoral neck fracture/other disease),time of diagnosis with DVT (during hospitalization/after discharge).Results Among 40 proximal DVT cases,31 cases diagnosed by phlebography and 9 cases were diagnosed by ultrasound.2 cases were isolated proximal DVT while 38 cases connected with distal DVTs.9 cases of blood clots in the proximal and distal thrombosis connected discontinuously.There was no isolated proximal DVT in TKA group and 10 cases (90.9％) of blood clots in the proximal and distal thrombosis connected continuously while there were 2 cases (6.9％) isolated proximal DVTs in THA group and 21 (77.8％) of blood clots in the proximal and distal thrombosis connected discontinuously,and there was no statistic significant difference between the two groups.The average length of proximal was 8.85±9.3 1cm (range from 2-35cm) with 5.0±2.05 cm in TKA group and 10.31 ± 10.55 cmin THA group.A significant difference was found between the 2 groups (P=0.014).13 cases located in femoral veins and upper venous region which were all from THA group.There was a significant difference in the distribution between surgery type and preoperative diagnosis.However,there was no significant difference between other potential factors and distribution of proximal DVT.25 cases accepted the evaluation of symptom of DVT before scanning.However,no significant difference were found in edema,VAS score,Homans sign,Neuof sign between 9 TKA and 16 THA cases.Conclusion Proximal DVTs after knee and hip arthroplasty are more preferred to connect with distal DVT continuously.Surgery type and preoperative diagnosis have a significant effect on the distribution of proximal DVT.Proximal DVTs in THA and patients with preoperative femoral neck fracture could be more easily involving femoral veins and upper parts.

Objective To observe the efficacy and safety of in-center nocturnal hemodialysis (INHD) in uremic patients. Methods Thirty-two maintenence hemodialysis (MHD) patients received INHD (3 times per week and 7.5 hours each session) for 6 months.Before and 1, 3 and 6 months after entering INHD, blood routine, hepatic and renal function,serum electrolyte, lipids, parathyroid hormone and β2-microglobulin(β2-MG) were assayed, Kt/V and URR were calculated. Blood pressure of each dialysis session 2 months before and 6 months after INHD was recorded. Cardiac ultrasound and SF-36 questionnaire before and after INHD were performed. Use of drugs was recorded. Results Compared with 2 months before INHD, predialysis BP decreased [(130.3/86.0) vs (139.3/88.6) mm Hg, P＜0.01], while post-dialysis BP raised significantly [(121.1/80.5) vs (115.0/77.8) mm Hg, P＜0.01] 6 months after INHD.Intradialysis hypertension (9.8%vs 24.0%) and hypotension (7.3% vs 14.9%) both reduced (all P＜0.01). Serum phosphorus [(1.37±0.27) vs (2.08±0.49) mmol/L, P＜0.01] and iPTH [(355.4±139.6) vs (632.3±750.0) ng/L, P＜0.01] decreased, while calcium increased [(2.64±0.25) vs (2.28±0.37) mmol/L, P＜0.01], HDL[(1.27±0.29) vs (0.75±0.08) mmol/L] increased, LDL [(2.04±0.52) vs (2.75±0.75) mmol/L] decreased (all P＜0.05). URR [(79.7±0.1)% vs (64.7±4.7)%] and Kt/V (1.40±0.44 vs 0.89±0.25, P＜0.01) increased. Serum β2-MG decreased [(17.3±3.9) vs (24.6±5.9) mg/L, P＜0.01]. LVMI decreased [(99.8±29.0) vs (114.8±72.7), P＜0.05]. Physical functioning, role-physical and role-emotional of SF-36 increased (all P＜0.01). The types of antihypertension drug, dosage of EPO, Vitamin D3 and phosphorus binder decreased (all P＜0.01).Patients of drug withdrawal increased (P＜0.05). Conclusion The hypertension, anemia,calcium-phosphorus metabolism, lipid disorder, cardiac malfunction and the quality of life are improved in INHD patients.

Myeloid differentiation factor MyD88 is a critical adaptor molecule that integrates and transduces intracellular signals in inducing the differentiation of dendritic cells (DCs).The domain regions within MyD88 was searched,it could potentially affect the function of dendritic cells and found that MyD88 aa155-171 motif not only regulate the activity of transcription factor NF-?B, but also control the production of cytokines and expression of costimulatory molecules. Indeed, aa155-171 motif deleted type MyD88 (MyD88155-171) transfected RAW264.7 cells exhibited the reduced NF-?B and AP-1 activity and interrupted the expression of CD86 and B7H1. Meanwhile, lower level expression of cytokines such as IL-12,IFN-? were also observed by means of cytokine array in MyD88-/-DC trasfected with MyD88155-171 as compared to the MyD88 transfected cells. Thus, aa155-171 motif inside MyD88 could affect the expression of costimulatory molecules, production of cytokines and transduction of Toll like receptor signal pathway, suggesting that this motif may play an important role in regulating responses of innate immune system.

Objective To explore the effect of urgotul used in wounds of the skin soft tissue injury.Methods 864 patients were divided into two groups:control group and observation group.After regular disinfection,patients in observation group used urgotul to cover wound surface and patients in control group used vaseline to cover it.Whether the patients appeared having hemorrhage,feeling pain,wound adhesion,change number and wound healing time were observed and compared at first dressing the next day.Results No wound adhesion occurred,39 cases felt pain and 22 cases had hemorrhage in observation group and 231,294 and 1660 cases in control group,respectively.The differences between the two group were significant (x2 =365.75,384.28,160.61,respectively;P＜0.05).The mean change number in observation group was (4.2 ±0.8) and (8.3 ± 1.5) in control group,and the difference was also significant (u=49.0,P＜0.01).Conclusions Urgotul,as a high protection dressing,is better than that of vaseline in having hemorrhage,feeling pain,wound adhesion,change number and wound healing time.

OBJECTIVETo observe the differences in the cytokine levels in the serum and ascites caused by Gram-positive or Gram-negative bacterial infection in patients with multiple organ dysfunction syndrome (MODS).

METHODSThe cytokines in the serum and ascites of the patients were examined by enzyme-linked immunosorbent assay in 27 patients with MODS due to Gram-positive (n=13) or Gram-negative (n=14) bacterial infection at day 1.

RESULTSThe levels of LPS and TNF-a were higher in the patients with Gram-negative bacterial infection than in patients with Gram-positive infection (P<0.05), but the levels of IL-6, IL-8 and IL-10 remained comparable between the two groups (P>0.05).

CONCLUSIONTesting of LPS and TNF-a in the serum and ascites of patients with MODS caused by Gram-positive or -negative bacterial infection may help to identify the pathogens for peritonitis resulting in MODS.
