BACKGROUND: Abnormal hematopoietic microenvironment is an important factor causing dyshematopoiesis. However, no consensus has been reached on the sensitivity of hematopoietic stromal cells to irradiation.OBJECTIVE: To observe the changes of marrow stromal cells (MSCs) cycle and DNA content during the early stage of irradiation damage in mice, so as to further understand dyshematopoiesis due to radiation and provide scientific basis to avoid deleterious factors in hematopoietic environment.DESIGN: Completely randomized grouping and randomized controlled study based on the experimental animals.SETTING: Central laboratory of altitude military affairs medical department and altitude research institute of preventive medicine department, a military medical university of Chinese PLA.MATERIALS: This study was carried out at the Experimental Animal Center of Third Military Medical University between October 2002 and April 2003. A total of 60 healthy male Kunming mice were randomly divided into irradiation damage group and healthy control group, each having 30 mice.METHODS: The 30 mice in irradiation damage group were exposed to 60Co-γ of irradiation at a dose rate of 1.27 Gy/minutes within a distance of 4 m. Then the mice' marrow cells were harvested at day 3 and day 7 after irradiation, and were cultured in vitro for 14 days and 21 days for observation. Meanwhile the other 30 healthy mice unexposed to irradiation were considered as normal controls.MAIN OUTCOME MEASURES: Post-radiation number of MSCs colonies,cell cycle and DNA content.RESULTS: Although MSCs could grow and be adhered to walls after being exposed to irradiation of 5.0 Gy/s, the number of MSCs colonies was found significantly decreased compared to that of rnormal control group( P < 0.01 ).The colony number of the MSCs irradiated for 7 days obviously increased than that of MSCs irradiated for 3 days; however, MSCs recovered slowly and resulted in prolonged culture time, indicating the inhibited proliferation of MSCs due to irradiation damage. Results of flow cytometry showed that cells in G2+ M phase(2.60±0.41, 4.20±1.27) and DNA content (58.40±0.79,61.17 ± 1.35) in irradiation groups after 3-day and 7-day irradiation were obviously lower than those of normal control group(12.60 ±0. 75, 78.57±0. 83)(P <0.05-0.01).CONCLUSION: MSCs have relatively high sensitivity to irradiation damage and longer persisting period.

From August 2007 to January 2009 a total of 95 patients with complex renal calculi were treated with CT ( n = 32 ), X-ray ( n = 33 ) or ultrasound ( n = 30 ) guided percutaneous nephrostomy and ureteroscopic holmium laser lithotripsy respectively. The CT guided procedure had lower positioning time,positioning failure rate, complication rate and residual stone rate than those of X-ray and ultrasound localization, particularly had advantages in the stone clearance rate and complications rate ( all P ＜ 0. 05 ).CT guided localization can be chosen in the following conditions: higher kidney position, large staghorn calculi or renal pelvis stones without hydronephrosis, with congenital renal malformations or failure of ultrasound or X-ray localization.

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.
