OBJECTIVETo observe the clinical effect of chronic fatigue syndrome (CFS) treated with moxibustion at Gaohuang (BL 43).

METHODSWith stratified block randomization, 72 patients accorded with inclusive criteria were divided into a moxibustion at Gaohuang (BL 43) group (moxibustion group) and an acupuncture group, 36 cases in each one. In the moxibustion group, Gaohuang (BL 43) was treated with big moxa cones as the main acupoint, 10 cones a time; Qihai (CV 6) and Zusanli (ST 36) were added with big moxa cones, 7 cones a time. In the acupuncture group, acupoints were the same as those in the moxibustion group, and twirling reinforcing method was used after qi arriving, 60 times one minute and 360° with range. In the two groups, 10-day treatment was made into one course and there were two days between courses. The treatment was given once a day for 3 courses. Changes of fatigue assessment index (FAI) before and after treatment and clinical effects were observed.

RESULTSThe total effective rate was 88.9% (32/36) in the moxibustion group, which was better than 72.2% (26/36) in the acupuncture group apparently (P < 0.05). After treatment in the two groups, FAI scores were obviously declined compared with those before treatment (both P < 0.01) and FAI score in the moxibustion group was apparently lower than that in the acupuncture group (P < 0.05).

CONCLUSIONMoxibustion at Gaohuang (BL 43) can improve the FAI score of patients with CFS and the clinical efficacy is definite.

Objective To investigate the efficacy of hepatitis B vaccination in preventing hepatitis B (HBV) recurrence after liver transplantation for hepatitis B virus-related (HBV-related) recipients.Methods 30 healthy recipients who survived for more than 2 years after liver transplantation received vaccination using hepatitis B surface antigen (HBsAg)-containing vaccine.There were a total of 5 injections at 0 month, 1 month, 2 months, 3 months and 6 months respectively, and each dose was 40 μg.Thirty healthy adults who received hepatitis B vaccination during the same period were selected into the control group.The antibody of hepatitis B surface (Anti-HBs) titer was tested at 1 month, 2 months, 3 months, 6 months, 9 months and 12 months after the first vaccination.Results 6.7％ (2/30) of the liver transplantation recipients had good response (defined as a rise of Anti-HBs titer of more than 100 IU/L at 12 months after the primary vaccination), and 16.7％ of recipients (5/30) had partial response (Anti-HBs titer in 3 patients at less than 100 IU/L, Anti-HBs titer in 2 patients at more than 100 IU/L at first, then less than 100 IU/L after 12 months).For the 9 patients who received liver transplantation for acute liver failure, 2 had good response (22.2％) and another 2 patients (22.2％) had partial response.For the liver transplant recipients who survived for more than 5 years, 2 had good response (22.2％) and another patient (11.1％) had partial response.In the healthy control group, the good response rate was 73.3％ (22/30), and the partial response rate was 10％ (3/30).Conclusions Some HBV-related liver transplant recipients could acquire Anti-HBs by vaccination.Good response rate was lower in the HBV-related group of liver transplant recipients than in the healthy control group of people.Recipients for liver transplantation carried out for acute liver failure and recipients who survived for more than 5 years had higher response rates to HBV vaccination.HBV vaccination can be a way to prevent HBV recurrence in some liver transplant recipients.

Objective To investigate the effects and mechanisms of 1,25-Dihydroxyvitamin D3 [1,25(OH)2 D3] on hyperoxia-induced lung injury of neonatal rats.Methods Neonatal Sprague-Dawley rats were randomly divided into air group,hyperoxia group and 1,25(OH)2D3 group within 12 hours after birth,eight in each group.Rats in air group were exposed to air,while those in hyperoxia and 1,25 (OH) 2 D3 group were exposed to hyperoxia (≥85 ％ oxygen concentration).Rats in 1,25(OH)2D3 group were injected with 1,25(OH)2D3 0.5 μg/(kg · d) intraperitoneally once a dayfor seven days,meanwhile the rats in the other two groups received 0.9 ％ saline in the same way.All rats were sacrificed on day 7.Lung tissue sections were HE stained in order to assess lung histological changes and lung radical alveolar count (RAC).The levels of tumor necrosis factor-α(TNF-α),interleukin(IL)-1β and IL-6 mRNA were measured by real time-polymerase chain reaction.Analysis of variance and LSD test were applied for statistics.Results Compared with the air group,the weight of rats in the hyperoxia group was significantly lower on day 7 [(8.48±1.34) g vs (12.51±0.47) g,t=8.05,P＜0.05],while the weight of rats in 1,25(OH)2D3 group [(10.29±1.00) g] was higher than that in the hyperoxia group (t=3.61,P＜0.05).Lung tissue structure was normal in the air group.In the hyperoxia group,inflammatory exudation was observed in pulmonary interstitial,the alveolar size was uneven,and the RAC was lower than that in the air group (5.6±0.1 vs 6.8±0.2,t=21.45,P＜0.05).The RAC in 1,25(OH)2D3 group (6.2±0.1) was significantly increased compared with that in the hyperoxia group (t=11.76,P＜0.05),but still lower than that in the air group (t=9.69,P＜0.05).The expressions of TNF-α,IL-1β and IL-6 mRNA in hyperoxia group (0.0348±0.0006,0.0269±0.0003 and 0.0368 ± 0.0006) were higher than those in the air group (0.0111±0.0007,0.0040±0.0003 and 0.0162 ±0.0007,t=56.54,111.12 and 49.26,P＜0.05,respectively).The expressions of TNF-α,IL-1β and IL-6 mRNA in the 1,25 (OH)2D3 group (0.0203±0.0009,0.0141±0.0004 and 0.0251±0.0009) were lower than those in the hyperoxia group (t=34.44,61.93 and 27.99,P＜0.05,respectively),but higher than those in the air group (t=22.10,49.19 and 21.27,P＜0.05,respectively).Conclusions 1,25(OH)2D3 could attenuate hyperoxia-induced lung injury by inhibiting the expression of inflammatory cytokines.

Objective To explore whether chronic forced swimming stress could improve whole brain radiation induced cognitive dysfunction and possible mechanism. Methods Thirty-nine one month old male Sprague-Dawley rats were randomized into sham control group ( C ) , swimming group ( C-S ) , radiation group( R) , and radiation plus swimming group( R-S) . Radiation groups were given a single dose of 20 Gy on whole-brain. Rats in the swimming groups were trained with swimming of 15 min/d, 5 d/w. Rat behavior was performed 3 months after radiation in an order of free activity in an open field and the Morris water maze test including the place navigation and spatial probe tests. Then, the protein expressions of BDNF, P-ERK, T-ERK, P-CREB and T-CREB in the rat hippocampus tissue were assayed by Western blot. Results On the day 2, in the place navigation test of Morris water maze, the latency of swimming group was significantly shorter than that of sham group, the latency of sham group was significantly shorter than that of radiation group, and the latency of radiation swimming group was significantly shorter than that of radiation group(P<0?05). In the open field test, the latencies of the place navigation and spatial probe tests of Morris water maze had no significant difference among four groups (P>0?05). Western blot assay showed that the expressions of BDNF and its downstream signals including P-ERK and P-CREB were markedly reduced by radiation ( P < 0?05 ) , but this reduction was attenuated by the chronic forced swimming stress. Conclusion The chronic forced swimming stress could improve whole brain radiation induced cognitive dysfunction by up-regulating the expressions of BDNF and its downstream signal molecules of P-ERK and P-CREB in hippocampus.

Objective To assess the psychometric properties of the Chinese Heartburn Version of Quality of Life in Reflux and Dyspepsia Questionnaire (QOLRAD) in patients with gastroesophageal reflux disease.Methods 130 patients with symptoms of heartburn completed the Chinese version of QOLRAD,the Short-Form-36 (SF-36).30 of them received proton pump inhibitors (PPI) for 8 weeks,which was used to test responsiveness of the Chinese heartburn version of QOLRAD.Results The Chinese version of QOLRAD had acceptable internal consistency.The overall Cronbach's alpha was 0.89 and the internal consistency of dimensions ranged from 0.70～0.90.Content validity index (CVI) was 0.82.Confirmation factor analysis revealed a 5 factor solutions accounting for 62.02％ and most of items in their dimensions had acceptable loads (＞0.4).There was acceptable concurrent validity with correlations between the Chinese heartburn version of QOLRAD and Short Form-36 health survey ranging from 0.172～0.613.As to responsiveness,after therapy of PPI for 8 weeks,except the dimension of sleep disturbance,scores for dimensions of vitality,food/drink problems,physical/social functioning,emotional distress had significant changes.Conclusions The Chinese version of QOLRAD has a good reliability,validity and responsiveness to therapy,which can be used to assess the quality of life in patients with gastroesophageal reflux disease.
