Objective In Caucasian populations, the tumor cells of Epstein Barr virus (EBV)-positive classical Hodgkin lymphoma (cHL) patients more frequently express HLA class Ⅰ and HLA class Ⅱ molecules compared to EBV-negative cHL patients. HLA expression (in relation to EBV) in Asian cHL patients has not been previously investigated. Methods 145 cHL patients with formalin-fixed, paraffin embedded tissue blocks available from Beijing, China were randomly selected. Hematoxylin & Eosin-stained slides were used to reclassify the histological subtypes according to the WHO classification. EBV status was determined by visualization of EBER in tumor cells using in situ hybridization. Membranous expression of HLA molecules was detected by immunohistochemistry using antibodies HC-10 (class Ⅰ heavy chain) and antiβ2-microglobulin for HLA class Ⅰ, and CR3/43 for HLA class Ⅱ. Results EBV (+) tumor cells were observed in 40 % (58/145) of the cHL patients. As expected, the percentage of EBV(+) cases was much higher in the mixed cellularity subtype (71%) than that in the nodular sclerosis subtype (16 %) (P ＜0.001). The expression of HLA class Ⅰ was observed in 79 % of the EBV (+) cHL cases and in 30 % of the EBV (-) cases (P ＜0.001). For HLA class Ⅱ, 52 % of EBV(+) cHL cases were positive, compared to 43 % in EBV(-) cases (P =0.277). Conclusion The results in China population were similar to that in the Caucasian population for HLA class Ⅰ, but not for HLA class Ⅱ.

This article consults the literature on acupuncture-moxibustion treatment for the non-spastic stage of cerebral stroke published from 2001 to 2014, makes a summary and analysis from meridians, point selection, acupuncture reinforcing-reducing techniques and electoacupuncture application and points out some problems such as valuing acupuncture and neglecting moxibustion, valuing acupuncture and neglecting medicine, and neglecting point selection based on syndrome differentiation in acupuncture-moxibustion treatment for the non-spastic stage of cerebral stroke. The article also objectively assesses the position of acupuncture-moxibustion treatment, puts forward relevant solving ideas and emphasizes the importance of acupuncture manipulation and the necessity for combining Chinese herbal medicine to treat the non-spastic stage of cerebral stroke.

Hirschsprung's disease (HD) is a conginental disorder of enteric nervous system (ENS) and is associated with the abnormal migration of gut neural cerst cell (GNCC).Recent studies showed that the regulation of this migration is a complex gene network.By the development of epigenetic and stem cells,this network is becoming much more clear.Transplantation of the modified gut neural crest stem cells/gut neural crest precursors(GNCSC/GNCP) acquired from the HD bowl is becoming the potential therapy of HD.This paper summerizes the recent advances and is to promote better understanding the pathogenesis of HD.

Objective To investigate effects of sinusitis mixture on functional endoscopic sinus after surgery .Methods According random number table,36 cases of chronic nasosinusitis patients were divided into the treatment group and control group,the two groups were routinely 2%NaCl saline nasal irrigation,use of nasal corticosteroids and mucous discharging agent mixture used in postoperative patients with sinusitis in the treatment group oral therapy. Results The treatment group 100%,total efficiency in the control group (89%) (χ2 =4.36,P<0.05),there was a statistically significant difference.Conclusion Sinusitis mixture has significant efficacy on the recovery of patients afterfunctional endoscopic sinus surgery.

Objective To evaluate the effects of mechanical stretch preconditioning on pathological stretch-induced damage to type Ⅱ alveolar epithelial cells.Methods A549 cells cultured in vitro were randomly divided into 6 groups (n =5 each)using a random number table:control group (Ⅰ group),pathological stretch group (Ⅱ group) and different time mechanical stretch preconditioning + pathological stretch group (group Ⅲ-Ⅵ).A549 cells were exposed to 20％ cyclic stretch at 0.3 Hz for 6 h in Ⅱ group.In Ⅲ-Ⅵ groups,A549 cells were exposed to 5％ cyclic stretch at 0.3 Hz for 15,30,60 and 120 min,respectively,and then exposed to 20％ cyclic stretch at 0.3 Hz for 6 h.After the end of pathological stretch,the apoptosis in cells was detected using flow cytometry and was calculated.F-actin expression was determined using flow cytometry.Results Compared with group Ⅰ,the apoptosis rate was significantly increased,and the expression of F-actin was up-regulated in Ⅱ group.Compared with group Ⅱ,the apoptosis rate was significantly increased in groups Ⅳ-Ⅵ,and the expression of F-actin was up-regulated in groups Ⅴ and Ⅵ.Conclusion Preconditioning with mechanical stretch (30-120 min) can mitigate pathological stretch-induced damage to type Ⅱ alveolar epithelial cells.

To eliminate cancer hazards to human health,the development of the therapeutic cancer vaccine has been given more and more attention.By contrast of tradition therapy,cancer immunotherapy take the advantage of being able to achieve target therapy and take modest harm to organism.Here,we first idiscussed the mechanisms of cancer immune escape,and reviewed the design principles of therapeutic cancer vaccine,as well as the latest research progress of therapeutic cancer vaccine and its application.

LL-37 is the only member of the cathelicidin family known to exist in human acting as an endogenous antibiotic.After removal of the highly conserved N-termini of precursor hCAP18,a 15 000 C-terminal fragment called LL-37 bearing all of the known biological acivity hitherto is liberated by proteinase.LL-37 is active against both Gram-positive and Gram-negtive bacteria.Its antibacterial activity depends on the formation of ?-helical conformation.The cytotoxic activity of LL-37 is inhibited by apolipoprotein A-Ⅰ(apoA-Ⅰ) in the plasma,thereby it can function as a scavenger of LL-37 and prevent host cell damage.In addition to its microbicidal activity,LL-37 has several other functions such as chemotactic,angiogenic action and the ability to bind and neutralize the endotoxin.

Objective To compare the efficacy and safety of duloxetine and gabapentin in the treatment of diabetic peripheral neuritis .Methods 135 patients with diabetic peripheral neuritis were divided into the observation group(71 cases) and the control group (64 cases) according to random number table method ,and all patients received hypoglycemic therapy based on diabetes treatment principle .Furthermore,the observation group received oral duloxe-tine,while the control group was given oral gabapentin .The pain scores of all patients were evaluated using visual ana-log scale(VAS) and medical outcomes study (SF-36),and the adverse reactions were recorded during treatment . Results (1) Compared with before treatment ,both VAS scores and SF-36 scores in observation group and control group declined significantly at the end of 1st,2nd,4th week after treatment(all P<0.05),while there were no statis-tically significant differences in VAS scores and SF-36 scores between the two groups at the same time point ( all P>0.05).(2)The incidence rates of dry mouth ,drowsiness,fatigue and dizziness in observation group were significantly lower than those in control group (18.31% vs.34.38%,4.23% vs.26.56%,0.00% vs.23.44%,0.00% vs. 15.63%,χ2 =4.059,13.308,4.059,4.059,all P<0.05),while there were no statistically significant differences in incidence rates of nausea ,diarrhea and flustered between the two groups (all P<0.05).Conclusion The duloxetine and gabapentin in the treatment of diabetic peripheral neuritis have similar efficacy , but the duloxetine has better security.
