OBJECTIVETo systematically review the clinical efficacy of acupuncture on the patients with low back pain (LBP).

METHODSRandomized controlled trials (RCTs) about pure acupuncture therapy versus other treatments in treating LBP were electronically searched in PubMed, CBM, EMbase, The Cochrane Library, CNKI, VIP and Wanfang Data from January 2004 to May 2014. The observed index on the results were the changed scores of VAS, ODI, JOA and RMDQ. Two reviewers independently screened the literatures according to the inclusion and exclusion criteria, as well as the extracted data, and assessed the methodological quality. The results of Meta-analysis was conducted by RevMan 5.2 software.

RESULTSTen RCTs involved 751 patients were finally included. The results of Meta-analysis indicated that the role of pure acupuncture group in improving the VAS score was better than that of the control group, and the combined effect size was RR = -.32, 95% CI (-1.41, -1.22); Z=27.28, P<0.00001; the role of pure acupuncture group in improving the ODI score was better than that of the control group, and the combined effect size was RR = -5.07, 95% CI (-7.50, -2.65); Z=4.10, P<0.0001; the role of pure acupuncture group on improved JOA score was better than that of the control group and the combined effect size was RR=2.83, 95% CI (2.02, 3.63), Z=6.90, P<0.00001. The role of pure acupuncture group in improving the RMDQ score was better than that of the control group, and the combined effect size was RR = -2.80, 95% CI (-3.49, -2.11), Z=7.95, P<0.00001.

CONCLUSIONThe result of meta-analysis demonstrates that pure acupuncture may have a favorable effect on self-reported pain and functional limitations in LBP patients.

Objective To observe the status of oxidative stress and activity of alkaline phosphatase(ALP) in rats exposed to high fluoride for the different periods and to analyze the effect of fluoride on the activity of ALP and oxidative stress in fluorosis rats. Methods Twenty-four Wistar rats were divided into control and high-fluoride groups according to their body mass, 12 rats in each group. The control group drank tap water(sodium fluoride concentrations < 1 mg/L), and high-fluoride group drank tap water containing sodium fluoride(sodium fluoride concentrations 221 mg/L). On a standard diet and water available ad hbitum, each rat was measured body weight once a week in 1,4,8,12 week. The biochemical techniques were used to test the indicators of oxidative stress including malonaldehyde(MDA), superoxidedismutase(SOD), glutathione peroxidase(GPx), uric acid and activity of ALP in serum of fluorosis rats. Results There was a interaction between fluoride and time in the activity of ALP (F = 4.690,P < 0.05). The activity of ALP was obviously higher in rats exposed to fluoride for 1,12 week [ (19.29± 3.69), (15.72 ± 0.79)kU/L] compared to the control[ (14.08 ± 1.99),(12.91 ± 3.97)kU/L, all P< 0.05] ; the level of MDA was obviously higher in rats exposed to fluoride for 1,4 week [ ( 13.37 ± 4.38 ), ( 11.82 ± 2.08) μmol/L ] compared to the respective control[ (8.75 ± 3.24), (7.42 ± 2.62)μmol/L, all P < 0.05]; difference of SOD and GPx between control and high-fluoride groups was not statistically significant(all P > 0.05); the level of uric acid in serum was significantly higher in high-fluoride group for 1,4 week[ (89.53 ± 13.21 ), (88.47 ± 19.78 )μmol/L] compared to the control [ (77.79 ± 11.43 ), (65.42 ± i 3.42) μ mol/L, all P < 0.05 ], but the level of uric acid showed lower in high-fluoride group for 8,12 week [(67.21 ± 9.44), (73.95 ± 9.52)μmol/L] compared to the control [(77.79 ± 11.43), (65.42 ± 13.42)μmol/L]. Conclusions Effect of overdose fluoride on ALP is time-dependant. On the other hand,overdose fluoride stimulates the status of oxidative stress in a way unrelated to the exposure period.

Objective To study the influence of fluoride on the expression of Runx2 in suckling rat osteoblasts. Methods Osteoblasts obtained from calvarium of suckling Wistar rats were cultured in the media supplemented with NaF at different doses(0, 1,2 and 4 rag/L), and Runx2 Mrna expression and protein expression were evaluated by RT-PCR and ELISA, respectively. Results Runx2 Mrna expression in suckling rat osteoblasts cultured in vitro significantly increased after exposure to NaF for 48 h at different doses (0.613±0.055, 0.773±0.070 and 0.775±0.070 for 1,2 and 4 mg/L,respecfively) compared to the control (0.482±0.043 ,P< 0.05). Runx2 Mrna expression further increased after 72 h exposure to NaF(0.969±0.048,1.229±0.061,1.255± 0.063 for 1,2 and 4 mg/L, respectively) ,which is significantly higher than the control(0.724±0.036,P<0.05) and corresponding groups at 48 h. NaF doses and exposure time exhibited a significant synergistic effect on Runx2 Mrna expression (P<0.05). Similarly, NaF also enhanced Bunx2 protein expression in suckling rat osteoblasts cultured in vitro. Significant differences were observed between groups exposed to NaF (1,2 and 4 rag/L) and control at48 h post-exposure (0.141±0.007, 0.143±0.008, 0.143±0.011 vs 0.129±0.012, P<0.05) as well as 72 h post-expesure(0.156±0.014, 0.168±0.018, 0.162±0.0100 vs 0.137±0.016, P<0.05). In addition, Runx2 protein expression at 72 h post-exposure was significantly higher than that at 48 h. Conclusions The results suggested that NaF could increase Runx2 expression in suckling rat osteoblasts with a synergistic effect between the doses and exposure time.

Objective To observe the expression of fibronectin in bone of fluorosis rats and in vitro cultured osteoblast,and to study the role of fibronectin in pathogenesis of chronic fluorosis.Methods Male and female Wistar rats 144 were randomly divided into four groups,which were designated as the control group(normal diets,n =36),fluoride group(normal diets + 100 mg/L fluoride,n =36),lower calcium monophagia group (synthetic diets,n =36) and lower calcium monOphagia with fluoride group(synthetic diets + 100 mg/L fluoride,n =36).Rats were sacrificed 4 and 8 months after beginning of the experiment,respectively,and femur tissue was fixated and paraffin-embedded.The osteoblast isolated from calvaria of neonatal rats was treated with different dose of fluoride(0,1,2,4 mg/L fluoride,respectively) for 48 and 72 h,cell culture supernatant and cells were collected,respectively.The cranial osteoblasts were cultured in vitro and divided into four groups according to different concentration of fluoride added,which were 0(control group),0.01,1.00,and 10.00 mg/L groups.These cells were treated with mineralized induced medium at day 2 and cultured for 3 more weeks whereafter,and then the slides were fixed in alcohol.The expression of fibronectin in rat femur tissue was detected by immunohistochemistry (IHC),and fibronectin mRNA expression was determined by in situ hybridization; the fibronectin levels in supernatant of cultured osteoblast was examined by enzyme-linked immunosorbent assay(ELISA),and the expression of fibronectin mRNA in osteoblasts was detected with RT-PCR; skull mineralized nodule formation of osteoblasts was observed under a light microscopy after stained with 0.1％ red alizarin liquid.Results Little expression of fibronectin (brown granules under light microscope) could be seen in femur tissue of fluorosis rats of control group and lower calcium monophagia group; but abundantly expressed in fluoride group and lower calcium monophagia with fluoride group; the fibronectin was also expressed in osteoblasts,bone cells and bone marrow cells with less red particles in the control group and lower calcium monophagia group,but more in the fluoride group and lower calcium monophagia with fluoride group.The expression of fibronectin protein in supernatant of cultured osteoblasts was significantly increased in the group of 4 mg/L fluoride at 48 h(0.108 ± 0.042,t =0.764,P＜ 0.05) compared with control group(0.081 ± 0.010); the value was also significantly increased in 1,2,4 mg/L groups at 72 h(0.089 ± 0.010,0.087 ± 0.012,0.098 ± 0.023; t =0.765,0.704,0.996; all P ＜ 0.05) compared with control group (0.070 ± 0.014) ; the expression of fibronectin mRNA was much higher in 1,2,4 mg/L groups at 48 h (0.61 ±0.06,0.77 ± 0.07,0.77 ± 0.07) and 72 h(1.61 ± 0.14,2.54 ± 0.20,2.75 ± 0.22) compared with control group [0.48 ± 0.04(t =0.111,0.182,0.182,all P ＜ 0.05),0.97 ± 0.08(t =0.093,0.109,0.108,all P＜ 0.05) ].A lot of mineralized nodules could be seen under light microscope in 1.00 and 10.00 mg/L groups.Conclusions The expression of fibronectin in bone of fluorosis rats and in vitro cultured osteoblasts are increased,and fluoride also promotes the mineralization nodules formation of osteoblasts.These results suggest that fibronectin may regulate the process of bone mineralization,and possibly play a role in the development of skeletal fluorosis.

Objective To study the influence of fluoride on the expression of osteoprotegerin(OPG) mRNA and protein in suckling rat osteoblasts. Methods Osteoblasts obtained from calvarial of suckling Wistar rats were cultured in vitro in the media supplemented with NaF at a series of doses[O(control), 1,2 and 4 mg/L groups], and OPG mRNA expression and protein were evaluated by RT-PCR and ELISA methods, respectively. Results OPG mRNA expression in suckling rat osteoblasts cultured in vitro significantly increased after exposure to NaF for 48 h and 72 h(F=333.48,808.34,P<0.05). OPG mRNA expression in suckling rat osteoblasts cultured in vitro after exposure to NaF for 48 h at different doses(0.810±0.003, 0.819±0.031 and 0.870±0.044 for 1,2 and 4 mg/L groups, respectively) compared with that of control (0.800±0.040, all P<0.05). OPG mRNA expression further increased for 72 h exposure to NaF(0.933±0.047,1.031±0.051,1.240±0.062 for 1,2 and 4 mg/L, respectively), significantly higher than that of the control (0.805±0.020,all P<0.05) and corresponding groups at 48 h. NaF doses and time exposure exhibited a significant synergistic effect on OPG mRNA expression(F=2004.16, P<0.05). NaF also enhanced OPG protein expression in suckling rat osteoblasts cultured in vitro. Significant differences were observed only in 4 mg/L group(0.228±0.014,0.277±0.048) and control(0.205±0.012,0.229±0.010) at 48 h and 72 h (P<0.05). In addition, OPG protein expression at 72 h post-exposure was higher than that at 48 h,but there was no synergistic effect between concentration and time(F=1.21,P>0.05). Conclusions The results suggested that NaF could increase OPG mRNA and protein expression in suckling rat osteoblasts with a synergistic effect between the doses and exposure time.

OBJECTIVETo explore the effectiveness of intravenous immunoglobulin (IVIG) in treating patients with unexplained recurrent spontaneous abortion (URSA) and the effect of IVIG on the level of soluble human leucocyte antigen G (sHLA-G).

METHODSThis prospective trial conducted at PUMC Hospital between 2004 and 2008 included 60 women with URSA. The patients were allocated into IVIG group (30 cases) and control group (30 cases). IVIG was intravenously used before conception at a dose of 0.2g/kg; once pregnancy was confirmed,IVIG was continued every 4 weeks till the 20th gestational week. Traditional Chinese medicine or/and progesterone were used in control group. The outcome of pregnancy was evaluated by live birth rate and effective rate(defined as the embryo living 4 week longer than previous pregnancy). Serum samples were collected randomly before pregnancy and in the 6th-8th gestational week from IVIG group (15 samples),control group (15 samples),and healthy women (20 samples). The levels of sHLA-G,interferon γ (IFN-γ), interleukin-2 (IL-2), and interleukin-10 (IL-10) were determined by enzyme-linked immunosorbant assay (ELISA).

RESULTSThe pregnancy rate was 93.3% in IVIG group. The live birth rate and effective rate were 85.7% (24/28) and 92.9% (26/28) in IVIG group,which were significantly higher than those in control group [56.7% (17/30) (P=0.021) and 63.3% (19/30) (P=0.011)]. Emesis occurred in one woman (3.3%) in IVIG group had during IVIG infusion but was relieved by lowering the speed of infusion. The mean sHLA-G level was (61.37∓35.57) U/ml in control group and (62.70∓37.24) U/ml in IVIG group (P>0.05); both of them were significantly lower than that of healthy women (88.49∓25.37) U/ml (Pü0.05). After pregnancy was achieved, the levels of sHLA-G and IL-10 were (34.19∓14.21) U/ml and (11.71∓2.75) pg/ml, respectively in the IVIG group, which were significantly higher than those in control group [(23.71∓12.83) U/ml and (8.71∓3.01) pg/ml, respectively] (P=0.008).

CONCLUSIONSLow-dose IVIG before and after pregnancy is a safe and effective in treating URSA. IVIG improves the development of fetus by up-regulating sHLA-G and IL-10 levels.

The clinical study was conducted to further evaluation the effectiveness and safety of Fangfeng Tongsheng granule in the treatment of sub-acute eczema (superficial cold and interior heat syndrome, exterior and interior sthenic syndrome). In the block randomized, multi-centered study, totally 108 patients were enrolled and assigned to two groups: 72 patients in the test group and 36 patients in the placebo control group. Those in the test group took Fangfeng Tongsheng granule with the dose of 3 g, twice a day, while those in the control group were give simulated agent granules with the same dose. The therapeutic course lasted for 14 days. Their efficacies in TCM syndrome, dermal symptoms and adverse events were observed. According to the test results, except for the one exit case, all of the remaining 108 cases, including 71 in the test group, and 36 in the control group, completed the clinical trial. As for the efficacy of TCM syndrome, after the medication for 2 weeks, the cure rate was 33.81% (24/71) in the test group and 0% (0/36) in the control group (P < 0.01), with a statistical difference between the two groups. Regarding the TCM score, after the medication for 2 weeks, the test group decreased by (12.82 +/- 7.96), while the control group decreased by (3.67 +/- 4.12), indicating a statistical difference between the two groups. As for the efficacy of dermal symptoms, after the medication for 2 weeks, the cure rate was 25.35% (18/71) in the test group and 0% (0/36) in the control group, with a statistical difference between the two groups. Regarding the dermal symptom score, after the medication for 2 weeks., the test group decreased by (10.04 +/- 7.17), while the control group decreased by (2.33 +/- 3.57), indicating a statistical difference between the two groups. There was no significant adverse event caused by Fangfeng Tongsheng granule. In conclusion, Fangfeng Tongsheng granule was effective and safe in treating subcute eczema (superficial cold and interior heat syndrome, exterior and interior sthenic syndrome).
