Objective To analyze the risk factors of nosocomial infection in patients with postpartum hemorrhage and the distribution of common pathogens, and to provide basis for reducing the infection incidence in patients with postpartum hemorrhage.Methods 134 patients with postpartum hemorrhage admitted from Jan. 2011 to Dec.2013 in our hospital were studied.The incidence of infection was observed in patients, and clinical data of patients were analyzed by univariate and multivariate Logistic regression.The risk factors of infection were was observed and blood samples from infected patients were analyzed to observe the distribution of common patho-gens.Results Among the 134 cases, 42 cases had puerperal infection, accounting for 31.34%, and 4 cases had obstetric wound infection, accounting for 2.99%.Univariate analysis showed that advanced maternal age, high-risk pregnant women, midwifery or cesarean section, invasive treatment, and long hospital stay were risk factors for infection.Logistic regression analysis showed that high-risk pregnant women, midwifery or cesarean section, invasive treatment, and long hospital stay were independent risk factors for infection.52 pathogens were detected from 46 patients.28 Gram-positive bacteria were identified, of which 15 cases of were staphylococcus aureus, accounting for 28.85%and 22 Gram-negative bacteria were identified, of which 11 were escherichia co-li, accounting for 21.15%.Conclusions Gram-positive bacteria are the majority in patients with postpartum hemorrhage and infection.High-risk pregnant women, midwifery or cesarean section, invasive treatment, and long hospital stay are independent risk factors for infection.Puerperal infection also need to be noted when post-partum hemorrhage occurs.

ObjectiveTo estimate the value of serum soluble scavenger receptor CD163 (sCD163) to the prognosis of patients with stroke associated pneumonia (SAP).Methods A prospective study was conducted. The clinically suspected SAP patients admitted to Department of Intensive Care Unit (ICU) and Emergency ICU (EICU) in Zhejiang Province Zhuji City Chinese Medicine Hospital from February 2014 to January 2015 were all enrolled. According to clinical pneumonia severity index (PSI), they were divided into SAP group and non SAP group according to the presence or absence of SAP, the patients of SAP group were subdivided into mild SAP group (PSI grade Ⅰ-Ⅲgrade) and severe SAP groups (PSI grade Ⅳ-Ⅴ grade) and according to the 28-day prognosis, the patients were subdivided into hospitalized death group and survival group. The clinical data were collected, including gender, age, history of stroke presence or absence, present stroke pattern, National Institutes of Health Stroke Scale score (NIHSS) on the day of stroke suspect diagnosis, Glasgow coma scale (GCS) score, acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ) score, clinical pulmonary infection score (CPIS), PSI score, body temperature, result of chest X-ray film, oxygenation index (PaO2/FiO2), result of sputum culture, serum levels of white blood cell (WBC) and C-reactive protein (CRP) in a period of 7 days after the suspected diagnosis, PCT, sCDl63 levels on days 1, 3, 5, 7 days, length of stay in ICU, the total time of hospitalization and 28-day survival situation, etc. The ability of each index to evaluate the prognosis of SAP was analyzed by the receiver operating characteristic curve (ROC curve). The risk factors influencing the prognosis of SAP patients were analyzed by multivariate logistic regression analysis.Results ① Seventy-eight patients were finally enrolled in the study, 44 patients were diagnosed as SAP, 34 were non SAP. In 44 patients with SAP, there were 28 cases of severe SAP and 16 cases of mild SAP. On the first day of the suspected diagnosis, the NIHSS score [13 (7, 22) vs. 8 (4, 17), the CPIS score [6 (4, 9) vs. 4 (3, 5), sCD163 [mg/L: 0.80 (0.59, 1.32) vs. 0.33 (0.22, 0.46)], CRP [mg/L: 84.2 (50.8, 114.9) vs. 51.4 (26.2, 79.9)] and 28-day mortality [38.6% (17/44) vs. 11.8% (4/34)] in SAP group were significantly higher than those in non SAP group (allP < 0.05), and other basic indexes between the two groups were all of no statistical significant differences (allP > 0.05). ② The levels of sCD163 reached the peak value on the third day after the suspected diagnosis among SAP group and non SAP group, mild SAP group and severe SAP group, survival group and death group and then began to fall; the levels of sCD163, WBC, CRP, PCT within 7 days in SAP, severe SAP and death groups were higher than those in non SAP, mild SAP and survival groups (allP < 0.05). ③ROC curve analysis indicated: sCDl63 showed a better capacity for evaluating the 28-day prognosis of SAP [ROC curve (AUC) =0.673, 95% confidence interval (95%CI) = 0.515-0.807, sensitivity and specificity were 41.2% and 96.3% respectively and the cut-off was 2.65 mg/L]. However, the levels of other inflammatory indexes and scores on the first day after the suspected diagnosis had no value for early prognosis of SAP. The multiple logistic regression analysis showed that the level of sCD163 on the first day after the suspected diagnosis was the independent risk factor of death in hospital of SAP patients [dominance ratio (OR = 1.27, 95%CI = 1.06-1.52,P < 0.05]. Age (OR = 1.04, 95%CI = 1.01-1.06,P = 0.015), NIHSS score (OR = 2.86, 95%CI = 1.64-4.92,P = 0.010), CPIS score (OR = 1.52,95%CI = 1.28-1.90,P < 0.001) and APACHEⅡ score (OR = 2.06, 95%CI = 1.53-3.07,P < 0.001) were also the risk factors of influencing the death of patients with SAP.Conclusions Early sCD163 level is an independent risk factor in predicting the 28-day mortality of patients with SAP, and it has a certain value for the prognosis of SAP.

OBJECTIVE To study the clinical efficacy of voice training on voice recovery in patients with vocal cord polyps during perioperative period.METHODS A total of 72 patients with vocal cord polyp were chosen in this study and they were randomly divided into study group and control group. After operation, the control group received routine treatment, and the study group received voice training on the basis of routine treatment. The results of voice acoustic analysis in the two groups were compared at 8 weeks after operation.RESULTS After 8 weeks, the maximum phonation time(MPT), dysphonia severity index (DSI) and the highest frequency(F0-High) of the study group were significantly higher than that of control group (P<0.05). The fundamental frequency perturbation(Jitter) of the study group was markedly lower than that of the control group(P<0.05). There was no statistical difference in the fundamental frequency(F0), the lowest intensity(I-Low) and amplitude perturbation(Shimmer) between the two group (P>0.05).CONCLUSION Voice training in the early postoperative period of vocal cord polyps was helpful to the recovery of the voice.

102 cases of Tourette's syndrome were divided into three types of the liver and kidney yin deficiency, phlegm and damp blockage and spleen and stomach deficiency.Acupuncture, auricular-plaster therapy, cupping therapy and herbal medicine were combined to treat this syndrome. As a result, 30 cases were satisfactorily effective, 61 cases were improved and 11 cases were ineffective with a total effective rate of 98.2% and no side effects were noticed during treatment.

Objective To explore the effects and mechanism of atrovastatin on the expression of the NF-κB in renal tissues of diabetic rats.Methods A total of 60 male SD rats was randomly taken out 40 rats to make diabetic model by injection of 65mg streptozotoein (STZ) into enterocoelia,the rest of 20 rats were normal control group.After the model made,atrovastatin (2 mg/kg/d) was given to the treated group,and the normal control group and diabetic rats without treatment group were given equivalent water.After 12 weeks,the rats were killed.Total RNA of the renal tissues was isolated from one kidney for each rat,and the renal tissues from the another kidney was prepared for immunohistochemistry (IHC) analysis.The NF-κB mRNA expressions among three groups were determined by RT-PCR.The distribution of NF-κB in the renal tissues was observed,and compared its difference among three groups.ResultsPCR showed that NF-κB mRNA was increased in the renal tissues of diabetic rats compared to control rats ( P ＜ 0.05 ).Drug-treated rats showed significantly decreased levels of NF-κB mRNA in the renal tissues compared to the untreated diabetic group( P ＜0.05).The results were also observed in protein lelel of NF-κB expression.IHC showed that there existed positive cells in the glomerular and renal tubulointerstitum.Conclusions Atrovastatin can down-regulate the expression of NF-κB and suppress the increased level of NF-κB protein in the renal tissue of diabetic rats,and slow the progress of retinopathy.

Objective: To investigate the mechanisms of moxibustion in the treatment of the colonic fibrosis in ulcerative colitis (UC) by observing the colonic fibroblast (CFB) synthesizing and secreting collagen in ulcerative colitis fibrosis rats. Methods: A rat model of ulcerative colitis fibrosis was established by immunological methods using human colonic mucosa as antigen adding local stimulation. The rats were randomly divided into normal group, model group, herb-partition moxibustion group, mild-warm moxibustion group and western medicine group (SASP group). Herb-partitioned moxibustion group and mild-warm moxibustion group treated by herb-partitioned moxibustion and mild-warm moxibustion respectively on Qihai (CV 6) and Tianshu (ST 25, bilateral) points. SASP group fed with salicylazosulfapyridine. Colonic fibroblasts from all the rats were isolated and cultured and the effects of moxibustion on the colonic fibroblast synthesizing and secreting type I, III, and IV collagen were observed. Results: The supernatant of cultured CFB from UC rats could stimulate the CFB of normal rats to secrete type I, III, and IV collagens. The supernatant from rats treated by herb-partitioned moxibustion and mild-warm moxibustion inhibited the secretion of type I , III, and IV collagens of CFB in normal rats. And the western medicine group also had some inhibiting effects on the type I and HI collagens. Conclusion: Moxibustion can regulate the functions of CFB synthesizing and secreting type I, III, and IV collagens in ulcerative colitis fibrosis rats.

Objective:To investigate the effects of acupuncture therapy on acute cerebral infarction. Methods: Eighty patients with acute cerebral infarction were randomly divided into a treatment group of 40 cases and a control group of 40 cases. Xuanzhong(GB 39)-through-Sanyinjiao(SP 6) acupuncture was performed as a main treatment. The curative effects were compared between the two groups and the sizes of cerebral infarct, between pretreatment and posttreatment after one course of treatment. Results: The total recovery rate was 88.5% in the treatment group and 57.5% in the control group after one course of treatment. There was a significant difference between the two(P<0.05). The rate of change in the infarct for the better was significantly higher in the treatment group than in the control group. There was also a significant difference(P<0.05). Conclusion: This treatment is an effective method for lowering the rate of apoplectic disability and raising the cure rate.

Objective To evaluate the effect of Jostent coronary stent-graft in endovascular treatment of traumatic carotid cavernous fistula. Methods Eight patients with traumatic carotid-cavernous fistula were treated by Jostent coronary steat graft from June 2001 to May 2007. Results The stent graft was successfully implanted in the target artery in all patients. The fistula in all patients was removed and the parent arteries kept unblocked. The clinical outcome was favorable, with no operation-related complications occurred. The ang4ogram showed normal patency of the parent arteries, without recanalization of the fistula six months after the stent graft implantation in six patients. Conclusions Stent graft is a useful tool for endovascular treatment of carotid cavernous fistula in selected patients. Further research is needed to optimize the stent graft for further use in cerebrovascular system.

Objective To investigate the utilization of contrast-enhanced ultrasound (CEUS) for the detection of splenic artery steal syndrome (SASS) after orthotropic liver transplantation (OLT).Methods Color Doppler flow imaging (CDFI) were performed at various time points post-operatively.CEUS and celiac angiography were conducted in patients suspected of SASS.Results 9 patients were suspected of SASS by slim or undetectable hepatic arterial Doppler blood signals by CDFI at various time points postoperatively.CEUS in 9 patients showed a delayed and weak contrast-enhanced blood signal in the hepatic artery associated with a rapid and intense enhancement of portal venous blood.No narrowing of a hyperintense signal was observed in the hepatic artery by CEUS.The 9 diagnoses of SASS were proven by celiac angiography.Conclusions SASS is identified as a sluggish and weak hyperintense blood signal in the hepatic artery without the narrowing and interruption of hypeintense signal in CEUS.CEUS is an effective imaging modality for detection of SASS following OLT.
