Thirty cases of peripheral facial palsy were treated with the comprehensive therapy, and 30 cases of peripheral facial palsy were treated with shallow electro-acupuncture as control. The results showed that the cure rate in treatment group was higher than that in the control group(P＜ 0.05), and no significant difference was found in effective rate between two groups.

OBJECTIVETo observe the efficacy of the treatment of refractory wound by VSD combined with platelet-rich plasma.

METHODSFrom April 2010 to June 2012,15 patients with refractory wound were treated including 11 males and 4 females with an average age of 35.2 years old ranging from 18 to 45 years old. The formation time of wound was from 6 to 24 months, which was unhealed after long-term medication or repeated treatment. The VSD combined with autologous platelet-rich plasma was applied to treat the wound. The wound healing was an indicator and treatment and clinical features were summarized.

RESULTSAll the patients were followed up for 3 to 8 months (means 5 months). The wound of all patients were healed without recurrence.

CONCLUSIONThe curative effect of VSD combined with platelet rich plasma for treatment of refractory wounds is obvious. It could reduce the treatment course and the treatment cost.

Objective:To study the change of immunological response and cell proliferation in breast tissues augmented by polyacrylamide hydrogel injection(PHI).Methods:The expression of CD68,CD25 and PCNA in 20 breast tissues with indurations,12 without indurations after breast augmentation by PHI,and 10 normal breast tissues was examined by immunohistochemistry P-V6000; analysis was also done by H-E staining.Results:Hyperplasia of fibrous tissue and infiltration of inflammatory cells and macrophages were found in the breast and adjacent tissues 3-8 years after PHI.Positive cells of CD68,CD25 and PCNA hardly existed in the normal tissues,but the breast tissues around the polyacrylamide hydrogel had many positive cells of CD68 and PCNA,especially in cases with indurations;there were significant differences between the 3 groups(P

Objective To investigate the relationship between postoperative cognitive dysfunc-tion and plasma cortisol levels in aged patients undergoing total hip replacement surgery. Methods Ninety patients aged 65-75 years old,scheduled for total hip replacement surgery under general anesthesia were enrolled in the present study.Cognitive state was tested by mini-mental state examination (MMSE).The patients were divided into two groups,POCD group and non-POCD group.Perioperative plasma levels of cortisol were determined on 2 d preoperative,2 d postoperative and 7 d postoperative.Results Incidence of POCD after 7 d in aged patients undergoing total hip re-placement surgery was 37.8%.Compared with day 2 d preoperative,plasma cortisol levels in POCD patients significantly increased on 2 d and 7 d post operation (P <0.01 or P <0.05).Compared with non-POCD patients,cortisol levels on the 2 d and 7 d postoperative day significantly increased in POCD patients (P <0.05).Plasma cortisol levels showed a negative correlation with MMSE scores on postoperative 2 d and 7 d(P <0.01).Conclusion Elderly patients have a relatively higher incidence of POCD after hip replacement surgery.POCD may be caused by high plasma cortisol levels in elderly patients following hip replacement surgery under general anesthesia.

Background:Single-balloon enteroscopy(SBE)is a new method for the examination of small intestine,its clinical value in suspected small intestinal diseases need to be further studied. Aims:To evaluate the diagnostic and therapeutic value of SBE in suspected small intestinal diseases. Methods:A total of 73 suspected small intestinal diseases patients who had undergone 81 SBE examinations from July 2011 to October 2013 at Chengdu Military General Hospital were retrospectively examined,indications,diagnostic and therapeutic value of SBE in suspected small intestinal diseases were analyzed. Results:Of all the 81 examinations,33(40. 7% )were obscure gastrointestinal bleeding,29(35. 8% ) incomplete intestinal obstruction,and 19(23. 5% )chronic abdominal pain or diarrhea. The intubation depth was 230 cm for the oral approach,and 100 cm for the anal approach. The diagnostic yield of SBE was 67. 9% ,the main lesions were small intestinal ulcer,small intestinal inflammation,small intestinal tumor,small intestinal polyp. A total of 8 patients underwent endoscopic therapy,of whom 5 underwent endoscopic hemostatic therapy and 3 underwent resection of polyp. No serious complications were found. Conclusions:SBE is a safe and reliable diagnostic and therapeutic method for suspected small intestinal diseases,and its main indications are obscure gastrointestinal bleeding and incomplete intestinal obstruction.

Objective To explore the relation between the infection of Helicobacter pylori (H .pylori)and colorectal tumor.Methods From January 2012 to January 2013,the medical data of 152 patients with colorectal tumor were collected.According to the findings of colonoscopy examination, the patients were divided into the colorectal adenoma group (84 cases)and the colorectal carcinoma group (68 cases).A total of 88 healthy individuals were also enrolled as control.The differences of H .pylori infection were compared among the colorectal adenoma group,the colorectal carcinoma group and the healthy control group.The distribution of H .pylori infection in different age,gender and nation was analyzed in colorectal tumor group.According to the location,maximum diameter,number,type of pedicle and pathological type of adenoma,the colorectal adenoma group was divided into subgroups and the condition of H .pylori infection was compared among the subgroups.Chi-square test was used in the statistical analysis.Results The positive rates of H .pylori infection of colorectal adenoma group, colorectal carcinoma group and healthy control group were 70.2% (59/84),72.1 % (49/68)and 53.4%(47/88),respectively,where the former two groups were both higher than that of the healthy control group,and the differences were statistically significant (χ2 =5 .147 and 5 .637,both P <0.05).Regarding the H .pylori infection,there was no difference in age,gender and ethnicity among 152 patients with colorectal tumor (all P > 0.05 ).Among 84 patients with colorectal adenoma,there was no statistical difference in the positive rate of H .pylori infection in different location,maximum diameter,number, type of pedicle and pathological type of adenoma (all P > 0.05).Conclusion H .pylori may have promoting effects on the genesis and development of colorectal tumor.

A chemiluminescence enzyme immunoassay based on magnetic microparicles (MmPsCLEIA) was developed to evaluate serum α-fetoprotein (AFP) in parallel with tramional colorimetric enzyme-linked immunsorbrnt assay (ELISA).A sestematic comparison between the MmPs-CLEIA and colorimetric ELISA concluded that the MPs-CLEIA exhibited fewer of immunoreagents,less total assay time,and better linearity,recovery,precision,senitivity and validity.AFP was detected in forty human serum samples by the proposed MPs-CLEIA and ELISA,and the results werecompared with commercial electrochemilunminescence immunoassay (ECLIA) kit.The correlation coefficient between MPs-CLEIA and ELISA was obtained with R2=0.6703; however,the correlation between MPs-CLEIA and ECLIA (R2=0.9582) was obviously better than that between colorimetric ELISA and ECLIA (R2=0.6866).
