This study was aimed to observe clinical effect of Wu-Fu Ma-Xin Gui-Jiang (WFMXGJ) decoction treatment for patients with nonspecific low back pain. A total of 60 nonspecific low back pain cases were selected and randomly divided into the treatment group and the control group, with 30 cases in each group. Patients in the treatment group were treated with modified WFMXGJ decoction, while cases in the control group were given rou-tine treatment of oral administration of nimesulide sustained-release tablets. Seven days were one treatment course. Comparison was made on Visual Analogue Scale/Score (VAS), clinical symptoms and body signs before and after treatment between two groups. The results showed that compared with pretreatment, low back pain were relieved with obviously improved VAS among patients in both groups (P<0.05). However, there was no significant difference between the treatment group and the control group. In the treatment group, acute low back pain VAS was obviously improved than the chronic low back pain VAS (P<0.05). There was no statistical significance between the acute and chronic low back pain in the control group. In the treatment group, the total effective rate was 93.33%;and the con-trol group was 73.33%. The clinical effect of treatment group was more significant than the control group (P<0.05). There was no statistical significance on acute and chronic low back pain in the treatment group and the control group. The recurrent rate of the treatment group was significantly lower than the control group (P<0.05). In the treatment group, the recurrence rate of chronic low back pain patients was higher (P<0.05). There was no significant difference on the comparison between acute and chronic low back pain in the control group. It was concluded that modified WFMXGJ decoction had obvious therapeutic effect on treatment of nonspecific low back pain, especially for the improvement of acute low back pain, with non-toxic side effects and low recurrence rate. It is worthy of fur-ther research and promotion.

Objective To evaluate the clinical application of perforator flap in extended radical vulvectomy of vulvar carcinoma.Methods Retrospectively,twelve cases of vulva carcinoma were treated by radical extensive excision,and the defects were repaired with perforator flap.Results All the flaps were survived and healed with first intention except one infection.The wound infection patient was treated with change of the dressing and antibiotics.The reconstructed vulvae were plump and elastic.It appeared like the normal vulvae and there was no contraction of the vagina.Conclusions Vulvar reconstruction with the perforator flap after the radical vulvectomy could make the patients recover easily,which produces almost normal appearance and function of the vulvae,reduces the time of wound healing,the patient could get the next therapy more quickly and the quality of life improving.It has wide clinical application value.

In order to explore the possible mechanism of EA (Electroacupuncture) in improving cognitive impairment, the present study was to research the effect of EA on the behavior and expression of the hippocampal neuronal nitric oxide synthase (nNOS) protein of the ovariectomized rats. Forty female SD rats were randomly and equally divided into four groups: sham group (ovarian fat around removal), model group (ovariectomy), sham EA group (sham EA stimulation after ovariectomy) and EA group (EA stimulation after ovariectomy). Two weeks after the ovariectomy, EA and sham EA were applied continuously for 3 months. In the experiment, Morris water maze was used to test the ability of spatial learning and memory, while enzyme-linked immuno sorbent assay (ELISA) and Western blot (WB) were used to detect the concentration of serum estradiol (E2) and relative expression of nNOS protein. The results showed that the escape latency of the EA and sham EA groups was shortened and the number of platform-crossing was significantly increased. The concentration of serum E2 and the expression of nNOS protein in both EA group and sham EA group were significantly elevated compared to those in the model group, while increment in the EA group was more significant (P<0.01). It could be concluded that from above experimental results, EA could be capable of improving learning and memory in ovariectomized rats by promoting the expression of nNOS protein through increasing the concentration of estrogen.

Objective To investigate the objective factors that affect the image quality of infant cranial CT using different mAs. Materials and Methods Ninety infants were divided into three groups randomly. The maximum anteroposterior diameter (MAPD) of skull of each infant was measured. Three reference levels, cerebellar, basal ganglia and centrum semiovale levels were selected respectively. Only one level was studied in each group and scanned with 150, 100 and 80 mAs. The subjective quality grade and the objective noise of all images were recorded and analysed statistically. Result The average MAPD of ninety patients was (148.0 ± 17.4)mm. On the cerebellar level, the subjective quality grade was lower than the other two levels, which were 6.3% , 9.4% and 22.9% respectively when mAs were 150, 100 and 80 mAs. Both quality grade of image and objective noise were significantly correlated with MAPD.Conclusion The inherent high noise of cerebellar level and MAPD were the objective factors that affect the image quality of low-dose cranial CT of infant.

OBJECTIVE To investigate the effect of diallyl sulfide (DAS) in protection against acute lung injury in rats induced by paraquat(PQ). METHODS A total of 100 male Wistar rats were randomly divided into normal control group,PQ 70 mg·kg-1 model group,and DAS 25,50 and 100 mg·kg-1 treatment groups,with 20 rats in each group. A poisoning model was estalolished after administration ig at a single dose of PQ 70 mg·kg-1,while the normal control group was ip given the same volume of normal saline. DAS 25,50 and 100 mg · kg-1 was intraperitoneally injected 30 min before and after PQ exposure. Five rats in each group were sacrificed at 1,3,6 and 12 h,respectively. The inferior lobe of the right lung was observed by HE staining under an optical microscope. Tissue of the upper lobe of the right lung was used to detect the content of nitric oxide (NO). Alveolar macrophages (AMs) were collected and cultured for 24 h,and the content of nitric oxide synthase(iNOS)in the supernatant was detected. AMs were cultured for 72 h and the expression of iNOS protein in AMs was detected by immunocytochemistry method. RESULTS Compared with normal control group,the alveolar structure of PQ group was severely damaged and the pathological score was significantly increased(P<0.01). The NO content of PQ group was significantly higher than in normal control group(P<0.01). The content and protein expression of iNOS were significantly increased in PQ group(P<0.01). Compared with PQ group,the lung injury score of rats in DAS 50 mg·kg-1 group at 3,6 and 12 h and in the DAS 100 mg·kg-1 group at each time point was decreased(P<0.05). Compared with PQ group,the NO content of DAS 25 and 50 mg · kg-1 group was decreased(P<0.05),and the NO content of DAS 100 mg · kg-1 group was significantly reduced(P<0.01). The content of iNOS was reduced in DAS 100 mg · kg-1 group(P<0.05). Compared with PQ group,the expression of iNOS protein in DAS groups was decreased(P<0.05). CONCLUSION DAS can inhibit the oxidative damage in rats induced by PQ.
