Varicella is an acute,highly contagious respiratory and caused by Varicella-zoster virus(VZV),After the primary infection,VZV induce Varicella,then the virus remains dormant in sensory nerve roots in life.Upon the reactivation,shingles can occur.Most of patients can recovery very soon,but kinds of potentially sever complication can induce death.Nowadays the VZV vaccination isn’t included in the expanded immunization program in our country. Varicella outbreaks take place at times in the middle of children of our country.The paper offers concise description about pathogen characteristics,diagnosis methods,clinical character,epidemiology knowledge and strategy of prevention.

Objective To compare the clinical efficacy and safety of Qingyi Decoction (a preparation of Chinese herbal medicine) between two different routes of the administration by using nasogastric tube or nasojejunal tube for treatmnent of severe acute pancreatitis (SAP).Methods A total of 79 SAP patients enrolled were randomly divided into nasogastric tube group (n =41) and nasojejunal tube group (n =38) according to the random number table method.In addition to the conventional therapy,they were treated with Qingyi Decoction administered by using nasogastric tube or nasojejunal tube.Results After treatment for 14 days,the levels of C-reactive protein (CRP),procalcitonin (PCT) and white blood cell count (WBC),urinary bladder pressure,and APACHE Ⅱ score in nasojejunal tube group were significantly lower than those in nasogastric tube group (P ＜ 0.05).The time required for the recovery of bowel sounds,length of abnormal serum amylase persistence,the duration of abdominal pain,the time necessary for mechanical respiratory support in nasojejunal tube group was significantly shorter than those in nasogastric tube group.The blood fungus infection rate and pulmonary fungus infection rate in nasojejunal tube group were significantly lower than those in nasogastric tube group,and 28-day survival rate in nasojejunal tube group was significantly higher than that in nasogastric tube group (P ＜ 0.05).Conclusion The nasojejunal tube route for the administration of Qingyi Decoction for the treatment of SAP can effectively alleviate the severity of patient's condition,shorten the time required for improving clinical symptoms,reduce the incidence of morbidity and mortality,and it is worthy of further popularization in clinical practice.

Objective To compare the application value and the clinical curative effect of longitudinal incision and tarsal sinus minimal-ly invasive approach in treatment of patients with intra-articular calcaneal fractures. Methods A retrospective statistical analysis was made by collecting and comparing the clinical data of 67 patients with intra-articular calcaneal fractures from March 2008 to March 2012,and they were divided into the longitudinal incision minimally invasive approach group ( ZW group,36 patients,37 feet) and the tarsal sinus minimally invasive approach group ( FW group,31 patients,33 feet) . The Bohler angle, Gissane angle before and after operation,complications healing time,and AOFAS scores were compared. Results The healing time,Bohler angle,Gissane angle of ZW group and other indicators were better than those of the FW group,but there was no significant difference between the two groups (P>0. 05). The infection of incision and compli-cations in ZW group was obviously less than those of the FW group (P<0. 05). According to the AOFAS scoring system,ZW group scored 82. 49 points while FW group scored 86. 53 points,which indicated no statistical significance (P>0. 05). Conclusion The two kinds of treatments are of no obvious difference,but the longitudinal small incision minimally invasive approach could receive better effect in terms of soft tissue damage,healing time,and postoperative complications.

Objective To explore the expression of naturally occurring plasma anti-? amyloid (A?) antibody in children and youngsters .Methods According to each 10 years, 28 healthy cases aged from 1~30 years old were diviedd to 3 groups.In the 3 groups,the plasma anti-A? antibody was detacted by immunostained with paraffin sections from Tg2576 mice brain to make a specific tissue amyloid plaque immunoreactivity (TAPIR) and immunoprecipitation analysis. Results The total occurrence rate of anti-A? antibody was 27.8%. There was no significant difference of TAPIR positive rate in each age group. They had the similar immunospecialties to middle-aged and elderly healthy controls. Conclusion Plasma anti-A? antibody can be occured before amyloid deposits and senile plaques in brain.

Objective To explore the value of left parasternal anterior mediastinaotomy (Chamberlain procedure) in the diagnosis of mediastinal lymph node enlargement with unknown causes and anterior mediastinal space-taking lesions. Methods By using the Chamberlain procedure, biopsy was performed in 32 cases of enlarged mediastinal lymph nodes with unknown causes or mediastinal space-taking lesions, which were found by CT scans. Results All of the 32 cases were pathologically diagnosed, with a diagnostic accuracy of 100%. Three patients with pericardial effusion received concurrent pericardial fenestration and then their symptoms relieved. Four patients underwent concurrent lung biopsy. The operating time was (48?15) min, the blood lose was ( 40.6?23.5) ml, and the postoperative hospital stay (3.6?1.4) days. No deaths or postoperative complications occurred. Conclusions Chamberlain procedure is a safe and valuable method in the diagnosis of mediastinal space-taking lesions with unknown causes or enlargement of the fifth and sixth groups of mediastinal lymph nodes, which routine mediastinoscope cannot reach. Some other simple therapies, such as lung biopsy or pericardial fenestration, can also be employed at the same time.

Purpose　To investigate whether thoracotomy can induce lung injury in the operative side and the protection by ambroxol in this procedure.　Methods　24 patients with esophageal carcinoma who were performed esophagectomy with anastomosis over the arcus aortae were randomized into 2 groups:an ambroxol group (ambroxol 1 g iv gtt qd×3,preoperatively) and a controlled group without any respiratory medication.General anesthesia by tracheo-cannula combined with continuous epidual anesthesia were used in all the patients.Bilateral broncho-alveolar lavage(BAL) was carried out after intubation preoperatively and before removal of the cannula postoperatively.Total Phospholipid(TPL),Saturated Phosphaytidylcholine(SatPC) and Total protein(TP) in the BALF were measured.The ratio of SatPC/TPL and SatPC/TP represented the activity of PS.　Results　In the controlled group,SatPC/TPL and SatPC/TP of the left lung(operation side) showed significant difference(P<0.05),compared with the right side(non-operation side).In the ambroxol group,no significant difference of such ratio was showed.　Conclusions　Thoracotomy can induce lung injury and bring out the decrease of PS and increase of protein exudation in the operative side.Large dose of ambroxol can promote in synthesize and secretion of PS and protect those changes.

Objective To analyze the safety, feasibility and operative technique details of non-grasping en bloc mediastinal lymph nodes dissection technique in uniportal video-assisted thoracic surgery(VATS) for lung cancer.Methods From April, 2014 to March, 2015,46 patients with lung cancer received non-grasping en bloc mediastinal lymph nodes dissection after uniportal VATS lobectomy.Clinical data of the cases were analyzed retrospectively.There were 19 males and 27 females.The age was(57.2 ± 9.0) (38-73) years.The first 6 cases were performed in the lateral decubitus position while the later 40 cases were all performed in the semiprone position.Results All cases accepted uniportal VATS non-grasping en bloc mediastinal lymph nodes dissection successfully.Arm fatigue of surgeon and assistant was obviously relieved when the patient was placed in the semiprone position.The thoracic drainage time was(3.2 ± 2.1) (1-12)days and the postoperative length of hospital-stay was(6.0 ± 4.5) (2-27) days.The number of dissected mediastinal lymph nodes stations was (4.3 ± 0.8) (3-6)and the number of dissected mediastinal lymph nodes was (11.8 ± 4.9) (4-30).There were 42 cases with stage No , lease wit stage N1, and 3 cases with stage N2 in pathological examination.Five patients developed minor postoperative complications.No perioperative death occurred.Conclusion Uniportal VATS non-grasping en bloc mediastinal lymph nodes dissection for lung cancer was safe and feasible, which could decrease the interference of the instruments and help to keep the surgical field clear.Non-grasping en bloc mediastinal lymph nodes dissection would be performed more smoothly in the semiprone position with less damage to lung and better ergonomics.

ObjectiveTo study the effects of rehabilitation training on the expression of brain derived neurotrophic factor(BDNF) around the cerebral infarcted area of rats.Methods60 SD rats were randomly divided into rehabilitation group and immobilization group 24 hours after cerebral infarction.The rehabilitation group were given water maze training,rotating bar and rolling cage exercises everyday while the immobilization group were fixed in cages. Histochemistry was used to detect the BDNF expression around the cerebral infarcted area at the 1st,3rd,7th,10th and 14th day after infarction respectively.ResultsAt 1st day after the infarction, the expression of BDNF increased obviously around the infarcted area in both group. More BDNF positive neurons were found in the rehabilitation group than that in the immobilization group at 3rd day (P<0.01). BDNF positive astrocytes showed obvious increasing in both group. BDNF positive neurons decreased with time going, and the color became lighter at the same time .At the 7th day after infarction, there were only a few positive neurons, and seldom obvious positive neurons could be seen around the infarcted area at 10th and 14th day. Great deal of BDNF positive astrocytes were found at 3rd,7th,10th and 14th day, and the rehabilitation group showed more expression than that of the immobilization group(P<0.01).ConclusionsThe rehabilitation training may increase the expression of BDNF which might take an active part in the recovery of the central nervous system injury and the rebuilding of its function.

Background and purpose:With the improvement of skill of video-assisted thoracic surgery, thoracoscopic anatomic segmentectomy becomes more and more mature. This paper aimed to study the safety, feasibility and clinical features of thoracoscopic anatomic segmentectomy for stageⅠ lung cancer.Methods:Data from 64 patients who was diagnosed as having clinicalⅠ stage lung cancer and received thoracoscopic anatomic pulmonary segmentectomy were retrospectively analyzed from Mar. 2008 to Jan. 2014. There were 28 men and 36 women with a median age of 59 years (39-86 years).Results:Sixty-four patients underwent thoracoscopic anatomic segmentectomy successfully. The median operative time was 120 min (90-240 min). The median blood loss in operation was 50 mL (10-200 mL). The median thoracic drainage time was 3 d(2-7 d). The median postoperative length of stay was 5 d(3-23 d). There was no postoperative mortality or severe complications. There was one conversion to lobectomy but no conversion to thoracotomy. There were 51 patients with ground glass opacity (GGO). Of the 51 patients, postoperative pathology showed invasive adenocarcinoma in 30, adenocarcinoma in situ in 10, minimally invasive adenocarcinoma in 6 and benign lesions in 5.Conclusion:Thoracoscopic anatomic pulmonary segmentectomy is a feasible and safe technique for a skilled doctor. Not only can it be a method of diagnosis, but also it can be a method of treatment for clinical stageⅠ lung cancer, especially for GGO in lung.

The development of informatization and modernization of traditional Chinese medicine (TCM) has been restricted to some degree due to the lack of sufficient modern scientific evidence to support TCM theory. Rapid development of computer technology, information and imaging technology, which can be used to explore TCM theory and mechanism, may bring hope to solve this problem. In recent years, functional Magnetic Resonance Imaging (fMRI) has been widely used to study TCM theory and mechanism. However, shortage of interdisciplinary talents those who possess both medical and engineering knowledge has restricted the development of fMRI research in the field of Chinese medicine. With the development of the discipline of TCM information science in TCM colleges and universities, students majoring in TCM information science will be the main source of researchers engaging in TCM fMRI researches. The flourishing development of TCM fMRI researches will cultivate a large number of talents adapting in TCM information science who will promote the construction of TCM information science.
