Objective To assess the quality reports on acupuncture in the treatment of postherpetic neuralgia. Methods MEDLINE, CBM, CMCC and CNKI from 1994 to 2006 were searched electronically. Handsearching was also done. The retrieved articles were assessed in terms of several factors, including the type of clinical research, methodology, diagnostic criteria, inclusion/exclusion criteria, effectiveness measurements, calculation of sample size, follow-up, etc. Results Among the 109 included articles, only 6 were true randomized controlled trials. There were 17 quasi-randomized controlled trials, 13 non-randomized concurrent controlled trials, 1 case-control study and 63 narrative studies. 29 of the reports clearly described the diagnostic criteria, 14 mentioned the inclusion/exclusion criteria, 79 reported the effectiveness measurements, none mentioned the calculation of sample size, 24 reported the follow-up outcomes, and only 1 mentioned adverse reactions. Conclusion More prospective, multicenter, large-scale, high-quality randomised trials are needed, and recommendations should also be made for future evaluations of methodological quality.
Objective To amplificate,clone and sequence the thymidine kinase (TK) gene of herpes simplex virusⅡ(HSVⅡ); to construct and appraise the fusion gene eukaryon expression vector, pcDNA3/HSVⅡ TK/angiostatin. MethodsThe Hep2 cells were infected by HSVⅡ Sav strain. HSVⅡ genomic DNA was purified from the Hep2 cells suspension and used as template to run PCR for TK gene amplification. The amplified products were cloned into PC DNA3 vector and sequenced. The vector pcDNA/HSVⅡ TK was cut by endonuclease. The gained TK gene was cloned into eukaryon expression vector. pcDNA3/angiostation, which had been constructed. ResultsCoding region of HSVⅡTK gene consisted of 1 128 bp except stop code, it encoded 376 amino acids.After cutting the new vector by endonuclease Hind Ⅲ and BamH Ⅰ,we gained the following gene fragment: 1000 bp (TK) and 700 bp (angiostation).Conclusion The fusion gene eukaryon expression vector， pcDNA3/HSVⅡ TK/angiostatin has been constructed.
Objective To investigate the effect of topical treatment with antisense oligonucleotides（ASON）targeting tumor necrosis factor-alpha;（TNF-alpha;）on the pathological process of experimental herpes simplex virus type-Ⅰ（HSV-Ⅰ）induced chorioretinitis in mouse eye. Methods Fifty BALB/c mice were randomly divided into experimental and control group（twenty five mice in each group）.HSV chorioretinitis model was induced in each mouse by inoculating 1times;105 plaque-forming units （pfu） of HSV-Ⅰ（KOS strain）into anterior chamber of the right eye.In experimental group，Fluorescein isothiocyanate （FITC）-labeled ASON targeting TNF-alpha; 2 mu;l were injected sub-conjunctiva in the left eye1day before and 1 and 4 days after the infection;while phosphate buffer solution was injected in the same way in control group.The inflammation changes of the eyes in the 2 groups were observed and the clinical grades were assessed according to the extends of anterior-chamber inflammation，vasodilatation of cornea and iris，formation of cataract，and vitreous opacity. All of the mice were executed 10 days after the infection and were observed histologically. The contents of TNF-alpha; in retina and choroid were measured by enzyme-linked immunobsorbent assay（ELISA）. Results After the infection，acute inflammation appeared in the right eyes in both groups. The inflammation of the left eyes in experimental group was significantly milder than which in the control group.Twelve left eyes had necrotic chorioretinitis in different degrees in the control group while 2 left eyes had mild chorioretinitis in the experimental group. The difference of the number of inflammatory cells between the 2 groups was statistically significant in retina，choroid，and ciliary body（P＜0.05）and was not obvious in anterior chamber，vitreous cavity，and iris（P＞0.05）.The content of TNF-alpha; in choroid and retina was（60plusmn;1.25）pg in the experimental group and（305plusmn;1.03）pg in the control group（P＜0.05）. Conclusions TNF-alpha; ASON treating HSV-Ⅰinduced chorioretinitis may reduce the content of TNF-alpha; in affected mice eyes and decrease the inflammatory reaction.

ObjectiveTo compare the analgesic effect of different treatment for herpes zoster neuralgia, and optimize herpetic neuralgia treatment. MethodsWe collected hospital inpatient data with herpes zoster by the First Military Medical Case Management System between January 1st, 2009 and December 20th, 2013. All the patients were divided into five groups according to different treatments. Patients in group A accepted valaciclovir capsules and doxepin hydrochloride tablets; patients in group B accepted valaciclovir capsules; patients in group C accepted valaciclovir capsule, nefopam hydrochloride tablets and doxepin hydrochloride tablets; patients in group D accepted valaciclovir capsules and nefopam hydrochloride tablets; patients in group E accepted valaciclovir capsules and non-steroidal anti-inflammatory drugs (including nimesulide capsules and ibuprofen sustained-release capsules). We collected such statistic data as sex, age, time of onset, time of pain disappearing after treatment. Then, we analyzed the difference among the groups on the time of pain disappearing. ResultsThere were 336 cases compliant with the standard in all the 898 cases of medical record data. The number of the patients was 72, 86, 66, 60 and 52; while the pain disappearing time after treatment was (5.94±2.54), (8.60±3.09), (5.77±1.85), (5.80±1.96) and (6.86±2.18) days, respectively in group A, B, C, D and E. Pain disappearing time after treatment of group B was significantly different from groups A, C, D, and E (P<0.05); group E was significantly different from groups A, C, and D (P<0.05); there was no significant difference between group A and groups C and D, and between group C and D (P>0.05). ConclusionThe combination of nefopam hydrochloride tablets, doxepin hydrochloride tablets, nimesulide capsules, and ibuprofen sustained-release capsules is effective in the treatment of herpes zoster neuralgia. The use of nefopam hydrochloride tablets with doxepin hydrochloride tablets is more effective than the combination of nimesulide capsules and ibuprofen sustained-release capsules. Doxepin hydrochloride tablets are not significantly different from nefopam hydrochloride tablets. Nefopam hydrochloride tablets and doxepin hydrochloride tablets are not associated with increased efficacy.
