OBJECTIVETo compare two kinds of method for treating lumbar tuberculosis with psoas abscess, to provide reference for clinical reasonable select of therapy treatment.

METHODSFrom January 2010 to January 2013,42 patients with lumbar tuberculosis combined with psoas abscess with obvious surgical indications were enrolled, including 24 males and 18 females with an average age of (38.5 ± 10.2) years old ranging from 21 to 63 years old. All patients were followed up for 18 to 24 months with an average of 20.9 months. Twenty-two patients underwent posterior vertebral body lesions cleared, bone graft fusion and internal fixation and percutaneous puncture catheter drainage for treatment of psoas major abscess as group A, and twenty patients underwent one-stage extraperitoneal approach to remove abscess, posterior vertebral body lesions cleared, bone graft fusion and internal fixation as group B. The operative time, loss of blood, length of hospital stay, clinical cure rate and other clinical results for the two groups were analyzed and compared.

RESULTSThe loss of blood was (452.3 ± 137.6) ml in group A and (603.5 ± 99.6) ml in group B, there was significant statistical difference (P < 0.05). The time of operation was (193.6 ± 91.2) min in group A and (230.5 ± 56.6) min in group B, there was significant statistical difference (P < 0.05). The time of operation and the loss of blood in group A were obviously less than which in group B. In group A 20 cases were cured and 2 cases relapsed, 19 cases were cured and 1 case relapsed in group B, there was no significant statistical differences between two groups regarding cure rate with chi-square test (χ² = 0.000, P = 1.000). All patients in two groups obtained good clinical curative effect. There were no significant statistical difference between two groups regarding for length of hospital stay with t-test (P > 0.05).

CONCLUSIONLumbar spinal tuberculosis with psoas abscess is not absolute indications for anterior open operation. Compared with the combined anterior and posterior surgical procedure, the percutaneous puncture catheter drainage combined with posterior debridement, interbody fusion and internal fixation can achieve the same clinical effect but less trauma for the patients.

Results The clinical effects were obviously better in group A than those in group B and group C ( P ＜ 0.05, P ＜ 0.01 ). Conclusion Chinese medicine together with oxygen and acupuncture can improve brain blood circulation, activate brain cells, increase the volume of brain blood flow and its blood supply, and enhance the clinical effects.

Objective · To observe effect of 17β estrodial (17β E2) with different concentrations on C type natriuretic peptide (CNP), insulin like growth factor 1 (IGF1), and natriuretic peptide receptor B (NPR-B) expression and proliferation of growth plate chondrocytes of rats in vitro. Methods · Eight Wistar rats were sacrificed and their epiphyseal cartilages of the upper tibias were separated to obtain chondrocytes on the 14th day after birth. Then chondrocytes were cultured with 17β E2 in different concentrations (10-4、10-6、10-8、10-10 and 10-12 mol/L) for 48 h, while control group was cultured without 17β E2. CCK8 method, ELISA and qRT-PCR were used to analyze the proliferation of chondrocytes, the levels of CNP and IGF1 in culture medium and mRNA levels of CNP, NPR-B and IGF1, respectively. Results · 17β E2 in different concentrations affected the proliferation of growth plate chondrocytes significantly. When the concentration of 17β E2 was 10-8 mol/L, it had the strongest effect on the cell proliferation. When the concentration increased to 10-4 mol/L, the proliferation of chondrocytes was inhibited. With the increasement of 17β E2 concentration, the levels of CNP in the culture medium and the mRNA levels of CNP in the chondrocytes were significantly different. The highest levels of CNP protein and mRNA both appeared in 10-8 mol/L group, while the lowest levels both appeared in 10-4 mol/L group. IGF1 and its mRNA also reached the highest levels in 10-8 mol/L group,but the lowest concentration and mRNA level were in 10-10 mol/L group and 10-12 mol/L, respectively. Both CNP mRNA and protein levels were positive correlated with the proliferation of chondrocytes (P=0.000). Nevertheless, there was no significant correlation between the proliferation of chondrocytes and IGF1 mRNA or protein levels (P>0.05). Conclusion · 17β E2 modulates proliferation of rat growth plate chondrocytes in a dose-effect manner. It enhances proliferation at relatively low concentrations (10-10-10-8 mol/L) and inhibits proliferation at high concentration. This effect is positively related to CNP expression in chondrocytes.

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.
