The post-stroke depression refers to a affective disorders within 2 to 3 years after stroke in patients with stroke.Its main features are depressed mood,decreased interest,irritability,pessimism,and slow thinking,etc.Usually the symptoms will last for more than 2 weeks.It is one of the most common complications of stroke and may seriously affect the rehabilitation and quality of life of patients.Some patients even have suicidal tendency.Early intervention is very important for late neurological recovery in patients with stroke.It can not only improve cognitive function,but also reduce the morbidity and mortality.This article reviews the treatment of post-stroke depression.

Objective:To explore the therapeutic efficacy of a new access to internal rigid fixation for mandibular condylar fracture. Methods: 7 patients with 9 unilateral mandibular condylar fractures were treated with preauricular beeline incisions. The two trunks of facial nerve were dissected and separated along the surface of the superficial temporal veins. Mandibular ramus periosteum was dissected. The fracture segments were reduced and fixed under sufficient exposure. Results: This operation access provided a sufficient exposure and was convenient for reduction and fixation. All the patients recovered effectively.Conclusion: This surgical approach is one of the feasible methods for reduction and fixation of mandibular condylar fracture.

Objective:To study the effect of Rhizoma Coptidis apozem on expression of AMP-activated protein kinase(AMPK) in skeletal muscle of metabolic syndrome rats. Methods:The models were established by administering high fat diet. Rats were randomly divided into five group: normal control group, metabriolic syndome group, Rhizoma Coptidis apozem group, Berberine group, Metformin group. To estimate insulin resistance by euglycemic hyperinsulinemic glucose clamp(GC) tecchnique. To estimate expression of AMPK by using Western blot. Results: Compared with metabolic syndrome group, Rhizoma Coptidis apozem group had higher M-value, lower wet weight of innards fat, and higher protein level of p-AMPK-?. Conclusion: Rhizoma Coptidis apozem can improve insulin resistance, decrease innards fat, and regulate up expression of AMPK.

Objective To investigate the effect of preoperative chlorhexidine bath for reducing the incidence of sur-gical site infection(SSI)in patients undergoing spinal surgery.Methods All patients who undergoing spinal surgery (with no implants)in the department of neurosurgery of a hospital between January 2013 and December 2014 were monitored,the selected patients were divided into control group (January-December of 2013,no intervention meas-ures were taken)and trial group(January-December of 2014,1 .8%-2.2% chlorhexidine bath for two nights before operation),incidence of SSI between two groups of patients before and after intervention was compared,interven-tions effect was evaluated.Results A total of 1 043 patients undergoing spinal surgery were enrolled,41 (3.93%) had SSI,incidence of SSI rates in control group and trial group were 6.47% and 2.34% respectively,the difference was statistically significant (P=0.001).According to the incidence of SSI in control group,actual infected patients in trial group were 27 less than the anticipated patients with infection.The average hospitalization expense in SSI group and non-SSI group were ￥33 641 .00 and ￥23 072.50 respectively,each patient could save ￥10 568.50 on average.Therefore,through the intervention measures,￥285 349.50 of hospitalization expense could be saved. Except ￥2 100 of trial material cost and ￥12 820 of manual labour cost,￥270 429.50 of social cost was ultimately saved.The mean length of hospital stay in control group and trial group were 10 (8-12)days and 9 (8-12)days respectively,rank test showed that the difference was not statistically significant (Z = - 0.68,P = 0.50 ). Conclusion Chlorhexidine bath intervention can not only reduce SSI rate,but also save the expense of hospitaliza-tion,whether it can shorten the length of hospital stay needs to be further studied.

Melamine is a kind of triazine compound and the fluorescence of it can get enhanced in the presence of cationic surfactant in weak alkaline medium. A new fluorescent spectrophotometry based on this principle) has been developed to determine melamine under the optimum conditions such as Tris-HCl buffer solution), pH 8.0 and with CTMAB as sensitizing agent. The linear range, detection limit and relative standard deviation were 25-1000 μg/L, 19 μg/L and 1.6%,respectively. The samples were pretreated according to the solid phase extraction monolithic column to carry out the detection of real milk. This method is simple, rapid and accurate. It can be used to screen and detect the milk samples primarily.

Objective:To assess the possible role of expression of TGFα and EGFR in nasal polyps and its re-lationship with PCNA labeling index. Method: Specimens from 20 patients of nasal polyps were studied with im-munohistochemical technique. Result: The expression of TGFα,EGFR and PCNA were increased in the epitheli-um, gland cells and inflammatory cells of nasal polyps. There was a close correlation between the intensities ofTGFα,EGFR and PCNA. Conclusion: TGFα may play a key role in epithelial cell proliferation in nasal polyps.

Objective To compare the efficacy and indications between the biliary bypass laparotomy surgery.and the two different kinds of biliary stent insertion surgery in the palliative alleviating jaundice of cholangiocarcinoma.Methods From March 2008 to March 2013,69 patients treated with palliative alleviating jaundice therapy of cholangiocarcinoma were included,who were all came from the Third Affiliated Hospital of Guangzhou Medical University.Including 17 patients who treated with the open biliary bypass surgery and 52 patients who treated with interventional therapy.We analysed the differences between these cases of biliary drainage operations in the recent jaundice reduction rate,average stay,mortality rate,the incidence of related complications,et al.Results All these different drainage ways had good effect in alleviating jaundice,incidence of alleviating jaundice have no obvious difference (P ＞ 0.05).Compared to the open biliary bypass surgery,interventional therapy had obvious advantages in the average stay and postoperative survival (P ＜ 0.05).The pancreatitis rate was lower in Percutaneous Group than that in Endoscopic Group (P ＜ 0.05).incidence of biliary tract infection and biliary tract bleeding have no obvious difference (P ＞ 0.05).There were no significant differences between the success rates of in biliary stent insertion operation in patients with each model cholangiocarcinoma (P ＞ 0.05).Conclusions Among the therapies of the palliative alleviating jaundice of cholangiocarcinoma,the internal biliary drainage of biliary stent insertion operation was superior to the treatment of the biliary bypass laparotomy.As to biliary stent insertion operations,endoscopic biliary stenting surgery should be the preferred choice.

Three hundred and nine community health service (CHS) practitioners were selected with randomized cluster sampling for survey with the job satisfaction questionnaire-occupational stress indicator (OSI).Degree of the job satisfaction was (68 ± 12)%.Position, work experience, income,feeling of recognition, degree of motivation, the scope for career development, the space for personal ambition and the relationship between salary and work load were potential influencing factors of job satisfaction to CHS practitioners.The authors suggest to establish the dynamic mechanisms of satisfaction study and to formulate comprehensive and effective incentive measures for CHS practitioners.

A new nested-polymerase chain reaction (nested-PCR) assay was developed to detect human parvovirus B19 DNA corresponding to the nonstructural protein in clinical specimens in a routine diagnostic laboratory. The sensitivity of this highly specific assay was up to 0.005 fg of B19 DNA. Parvovirus B19 was identified in sera of 20 pregnant women with abnormal pregnant outcome. Among these 20 cases, intrauterine parvovirus infection did exist in 7 pregnant women because parvovirus B19 DNA was detected in the pregnant tissues of them such as placenta tissues, chorionic villi, amniotic fluid, fetal spleen, liver and abdominal fluids.
