Objective:To investigate and analyze the current status of patient satisfaction and the influencing factors at private hospitals in Guizhou Province,and thus to provide a scientific basis for the management of medical service at private hospitals.Methods:The satisfaction scores were statistically described and analyzed by the factor analysis and multiple linear regression analysis.Results:The overall satisfaction score of patients was (3.87 ± 0.85),of which the satisfaction of medical technology,drug price,inspection fee,and medical facilities was lower.The factor analysis showed that satisfaction of patients at private hospitals could be classified into the environment,the quality of service,medical expense,and service flow.Multivariate linear regression results showed that its standardized partial regression coefficient by the parameter descending order followed as medical expense,the environment,the quality of service,and then service flow.Conclusions:Private hospitals should set up a fair medical expenditure mechanism,improve the environment and quality of medical services,and optimize service flow in order to improve patient satisfaction.

Aim To establish and evaluate the simple and effective animal model of rheumatoid arthritis in SD rats induced by heat-killed mycobacterium tuberculosis H37Ra(Mtb).Methods SD rats were immunized s.c.at the base of the tail with Mtb(1 mg/rat) in mineral oil,and then body weight,blood routine,clinical signs of arthritis were observed regularly.And also hind paw volume in SD rats with AA was tested.Meanwhile,T-lymphocyte subset was determined by flow cytometry in peripheral blood,the level of TNF-?in serum and IL-1 and IL-6 and vascular endothe-lial growth factor(VEGF) in joint tissue were tested by ELISA.The ankle pathological change and radiographic evidence of the hind paws of SD rats were observed to evaluate the AA model effects and availability in SD rats.Results When compared with normal control rats,the total number of white blood cells,platelets and monocytes in peripheral blood and ratio of CD4/CD8 was markedly raised after immunization with Mtb.But body weight of model rats was significantly low from day 14 to 28 after injection of Mtb.The inflammatory arthritic lesions such as edema and erythema in the paws appeared after 9～10 d.The peak of inflammation was 14～16 d.The level of TNF-?in serum and IL-1,IL-6 and VEGF in joint tissue was significantly higher in SD rats with Mtb than that in normal control rats at d 28.The histopathological examination revealed cellular infiltration,synovial and cartilage hyperplasia in ankle joints of SD rats.Conclusions The model induced by Mtb in SD rats is more similar in clinical characterization of rheumatoid arthritis in human being.It is a more efficient and simpler manipulative procedure for screening of new anti-arthritis drugs and experimental studying of anti-rheumatoid arthritis.

ObjectiveTo investigate whether early goal-directed therapy (EGDT) could improve the mortality rate in patients with severe sepsis or septic shock.Methods Articles were retrieved from PubMed, Cochrane Library, Embase data, Wanfang data, and CNKI from January 1980 to May 2015. Inclusion criteria included the subjects concerning patients with severe sepsis or septic shock reported as randomized controlled trial (RCT), clinical controlled trial (CCT), case-control studies, cohort studies with complete data, which endpoints were the short-term mortality [in-hospital, intensive care unit (ICU) or 28-day] and long-term mortality (60-day, 90-day or 1 year). RevMan 5.2 software was used for Meta analysis of effect of EGDT on mortality rate in patients with severe sepsis or septic shock, and funnel plot was drawn to evaluate the quality of enrolled literature.Results There were 12 studies meeting inclusive criteria including 5 528 patients, 4 RCTs, 3 case-control studies, 4 cohort studies, and 1 quasi-experimental research. It was shown by Meta analysis that EGDT was associated with significant decrease in the short-term mortality [relative risk (RR) = 0.72, 95% confidence interval (95%CI) = 0.64-0.80,P< 0.000 01], but not associated with decrease of long-term mortality (RR = 0.99, 95%CI = 0.92-1.06,P = 0.81). The funnel plot showed that there was no publication bias. EGDT was recommended as grade C.Conclusions EGDT was associated with significant improvement in short-term mortality but not with long-term mortality in patients with severe sepsis or septic shock. Grade C was recommended by our study.

Objective To observe the action ofFu Liu Zhen (acupuncture at the six abdominal points) plus moxa-box moxibustion at umbilicus on a community population of qi and yang deficiency.Method Two hundred subjects diagnosed with qi deficiency and/or yang deficiency were randomized into a treatment group and a control group, 100 cases in each group. The two groups both received constitution-associated health education, and the treatment group was additionally intervened byFu Liu Zhen plus moxa-box moxibustion at umbilicus, while the control group didn’t receive any other intervention. The Score of Constitution in Traditional Chinese Medicine (TCM) and the number of people of each constitution were observed prior to the intervention, right after the intervention, 6 months after the intervention and 12 months after the intervention.Result In the treatment group, the scores of qi deficiency and yang deficiency after the intervention, 6 months after the intervention and 12 months after the intervention were significantly different from that prior to the intervention (P<0.01). The scores of the corresponding constitution types (qi deficiency, yang deficiency) after the intervention, 6 months after the intervention and 12 months after the intervention were significantly different from that before the intervention (P<0.01). The proportions of subjects with harmonious constitution, qi deficiency, and yang deficiency in the treatment group after the intervention, 6 months and 12 months after the intervention were significantly different from that prior to the intervention (P<0.01). The proportions of subjects with harmonious constitution, qi deficiency, and yang deficiency in the treatment group after the intervention, 6 months and 12 months after the intervention were significantly different from that in the control group (P<0.01).ConclusionFu Liu Zhen plus moxa-box moxibustion at umbilicus can improve the qi-deficiency and yang-deficiency constitutions in the community population.

AIM To observe the endometrium receptivity of polycystic ovary syndrome patients and research advance of expression of HOXA10 in endometrium.METHODS Eighty PCOS patients were divided into treatment group and control group,40 persons in each group randomly.The control group was treated with clomiphene (CC) + human menopausal gonadotropin (HMG) + human chorionic gonadotropin (HCG),and the treatment group was treated with CC + HMG + HCG + Yin-Nourishing Yang-Supplementing.After 3 periods,take a record for below:endometrial thickness (Em) in the middle,advanced stage and mid-secretory phase of hyperplasia endometrii,the levels of spiral artery PI/RI in midluteum endometrium,the levels in serum of E2 and P in midluteum endometrium,the expression of HOXA10 mRNA from both groups,clinical pregnancy rate and abortion rate for each group.RESULTS Compared with the control group,endometrial thickness in the treatment group was increased and there is statistical difference in the middle and late follicle phases (P ＜ 0.05),but there was no statistical difference in midluteum endometrium (P ＞ 0.05);the level of E2 and P in the treatment group were raised (P ＜0.05) with statistical significance;PI and RI were obviously contracted (P ＜ 0.01).Expression of HOXA10 mRNA was increased (P ＜ 0.01).Compared with the control group,the treatment group had a significant difference in pregnancy rate (P ＜ 0.05).The abortion rate was lower,but there was no statistical significance (P ＞ 0.05).CONCLUSION Yin-Nourishing Yang-Supplementing Treatment can obtain higher pregnancy rate and lower abortion rate of PCOS patients and the mechanism might be associated with raising the expression of HOXA10 mRNA and reducing spiral artery PI/RI,also improving the function of corpus luteum treatment,then to improve the receptivity of endometrium.Yin-Nourishing Yang-Supplementing Treatment is well worth popularizing in further clinical application.

Objective To investigate the epidemiological and clinical characteristics, risk factors, outcome and prevention strategy of very low birth weight infant (VLBWI) with nosocomial infection in neonatal intensive care unit (NICU). Methods The VLBWIs whose birth weight were less than 1500 g and hospital stays were more than 48 hours in NICU of Peking University Third Hospital from January 1, 1998 to December 31, 2008 were selected in this study. They were divided into nosocomial infection group and non-infection group. The clinical features and outcomes of nosocomial infection were summarized and the risk factors of which were analyzed with Logistic regression. Results There were 158 VLBWIs who fit for the criteria of our study during the eleven years, the mean birth weight was (1263.8± 155.5) g and the mean gestational age was (30.4±2.1) weeks. There were 70 times and 56 cases suffered from nosocomial infections. The incidence of nosocomial infection was 35.4% and hospital stay-related incidence was 14.4‰. Among 70 times of infections, there were 40(57.1%) pneumonia, 22(31.4%) septicemia, 4(5.8%) thrush, 1(1.4%)conjunctivitis, 1 ( 1.4%) upper respiratory tract infection and 2 (2.9%) unknown site infections.Forty-one strains of bacteria were isolated from 121 specimens, among which gram-negative bacillus accounted for 56.1% and gram-positive cocci for 46.3%. The duration of hospital stay of VLBWIs with nosocomial infection was significantly longer than that without [(43.7±15.5) d vs (26.3±14.4) d] (t = -7.058, P＜0.01). The fatality rate of VLBWIs with and without nosocomial infection was 3.6% (2/56) and 3.9% (4/102), and there was no significant difference (x2 = 0.012,P＞0.05). Logistic regression showed that mechanical ventilation (OR = 3.388, 95% CI: 1.656-6.932, P=0.001) and parenteral nutrition (OR= 7.054, 95%CI: 2.005-24.813, P=0.002) were risk factors of nosocomial infection. Conclusions The incidence of nosocomial infection in VLBWIs in NICU is high. Mechanical ventilation and parenteral nutrition should be avoided and the duration of invasive operation and treatment should be shortened as much as possible to minimize the chances of nosocomial infection in VLBWIs.

Objective To discuss the clinical outcomes of old fracture-dislocation of proximal interphalangeal joint treated with a self-made distraction external fixator which consists of 3 pins and rubbers.Methods From March 2005 to August 2011,8 cases of old fracture-dislocation of proximal interphalangeal joint treated with a pins-rubber distraction external fixator were retrospectively reviewed.There were 6 males and 2 females,aged from 17 to 58 years,averaged 23.2 years.The middle finger was involved in 5 cases and ring finger was involved in 3 cases.The right hand was affected in six patients,and the left hand was affectd in two patients.The mechanism of injury was sports injury in 6 cases,traffic injuries in 1,and sprain in 1.All of the cases were closed injury.The mean time from injury to surgery was 58 d (range,45-90 d).According to Schenck classification of the proximal interphalangeal joint fracture-dislocation,there were 4 cases of type Ⅰ,3 of type Ⅱ,I of type Ⅲ.Based on the Michigan Hand Outcomes Questionnaire (MHQ) for subjective hand function score,the average preoperative score was 56; the range of motion of proximal interphalangeal joint was 0°.Grip strength was 60％-80％ of the contralateral hand.Results The follow-up lasted 6-51 months,with a mean period of 20.5 months.Solid bone healing was eventually achieved in all patients.The average healing period was 3 months (range,2-5 months).The mean normalized MHQ score was 88 (range,84-92).Grip strength was 85％-100％ of the contralateral hand.Extension of proximal interphalangeal joint was -10°-0° (average,-5°).Flexion angle was 75°-100° (average,89.4°).Postoperative complications included slight joint space narrowing (2 cases),joint incongruity (＜ 1 mm) (2 cases) and fusiform arthrocele (2 cases).No infection,pin loosening,and pin breakage was encounted.Conclusion A pins-rubber distraction external fixator is a minimally invasive,reliable and effective treatment for old fracture-dislocation of proximal interphalangeal joint.
