Objective To understand the iodine deficiency disorders in Xunhua county Qinghai province, and to provide reference values for setting up prevention and control strategy. Methods According to historical data of Xunhua county, 1 township center elementary school and 1 village elementary school were sampled in Qingshui, Baizhuang, Hongqi, Jiezi and Galeng townships. A total of 9 elementary schools were investigated (Caleng has only 1 elementary school). Fourty children aged 8-10 years were checked thyroid size by palpation in every school. Twenty children were chosen to assay their urinary iodine and edible salt iodine in every school. Thirty 5-grade students were surveyed by questionnaire on health education in every school. Ten housewives were inquired prevention knowledge on iodine deficiency disorders and salt iodine level was tested in every village. Results Goiter rate was 7.9%(30/378) in children aged 8-10 years, with Baizhuang and Galeng the highest (11.9%,5/42), and Qingshui the lowest (2.4%, 1/42). The median was 196.5 μg/L in children aged 8-10 years, and urinary iodine level lower than 50 μg/L was accounted for 5.3% (11/208), but that value was 25.0% (5/20)in Galeng. The average qualified rate of using edible salt was 91.4%(159/174), and that rates were 79.0%(15/19), 83.3%(15/18) and 89.5%(17/19) in Chajia, Tuanjie and Minzhu villages, respectively. The average score were 2.8, 2.1 in health education survey of the 5-grade students and housewives. Conclusions After years effort in prevention and control of iodine deficiency disorders, remarkable progress has been made in Xunhua County. The monitoring of iodized salt and the knowledge spreading are still need to be strengthened.

OBJECTIVETo observe the clinical effects of needle-pricking therapy, a newly medical and minimally invasive technique, for functional retrograde ejaculation and to explore its mechanism. Methods Thirty-six patients with functional retrograde ejaculation were randomly divided into an observation group(19 cases) and a control group(17 cases) In the observation group,needle-pricking therapy was used at Guanyuan(CV 4) and bilateral sacral plexus nerve,lumbar 1 nerve and greater occipital nerve stimulating points,once a week. In the control group, midodrine tablets were prescribed orally,three times a day. All the treatment was given for 9 weeks. The clinical effects of the two groups were observed, and the levels of luteinizing hormone(LH), testosterone(Tes) and estra4 diol(E2) were compared between the two groups.

RESULTSThe total effective rate of the observation group was, 89. 47%(17/19), which was better than 47.06% (8/17) of the control group(P<0. 05). The LH and Tes were obviously increased and E2 was decreased compared with those before treatment in the observation group(all P< 0. 01). Tes was raised(P<0. 05) and E2 was apparently declined in the control group(P<0. 01). After treatment, the differences of serum LH and Tes were statistically significant between the two groups(both P<0. 01).

CONCLUSIONNeedle-pricking therapy has advantages for functional retrograde ejaculation probably in that stimulating lumbosacral nerves can strengthen the function of pelvic floor muscles and urethral expansion muscle and regulate sexual gland axis.

OBJECTIVE: To investigate the optimal doses of X-ray irradiation and plasmid injection in the anti-tumor effect of the pcDNA3. 1-Egr. 1p-p16 gene combined with radiotherapy in vivo. METHODS: We observed the anti-tumor effect of the pcDNA3. 1-Egr. 1p-p16 gene combined with radiotherapy with different doses of X-ray irradiation (2, 10, 20 Gy) and plasmid injection (10, 20, 30 microg) in nude mice with JF-305 pancreatic carcinoma, and detected the expression of p16 in tumor by RT-PCR. RESULTS: The tumor growth rate of the nude mice irradiated locally with 20 Gy X-rays after the plasmid injection was significantly lower (P < 0.05 ) than that of the nude mice irradiated locally with 2 Gy or 10 Gy X-ray 3 days after the irradiation. The tumor growth rate of the nude mice injected locally with 20 microg or 30 microg plasmid was significantly lower (P <0.05 ) than that of the nude mice injected locally with 10 microg plasmid. Both pcDNA3. 1-Egr. 1p-p16 group and pcDNA3. 1-Egr. 1p-p16 +20 Gy group had p16 mRNA expression, but the mRNA level of pcDNA3. 1-Egr. 1p-p16 +20 Gy group was higher than that of pcD- NA3. 1-Egr. 1p-p16 group. CONCLUSION In the pcDNA3. 1-Egr. 1p-p16 gene combined with radiotherapy in vivo the optimal dose of X-ray irradiation was 20 Gy and the optimal dose of plasmid injection was 20 microg. The anti-tumor effect of pcDNA3. 1-Egr. 1p-p16 combined with radiotherapy is better than that of radiotherapy or gene therapy alone, which may be related with the enhanced p16 expression in tumor after the irradiation.

OBJECTIVETo compare clinical results of treating femoral head necrosis staged Ficat III or IV with total hip arthroplasty (THA) between mini invasive direct anterior approach (DAA) and posterolateral approach.

METHODSFrom January 2008 to December 2009, 48 patients with femoral head necrosis staged Ficat III or IV treated with THA were compared and analyzed. There were 21 patients in mini invasive direct anterior approach group including 11 males and 10 females with an average age of (65.2±4.3) years old;while there were 27 patients in posterolateral approach group including 16 males and 11 females with an average age of (63.6±4.0) years old. Operative time, blood loss during operation, bed rest time and complications of two groups were observed and compared. Acetabular abduction and stem shaft angle were measured 1 month after operation and compared between two groups. Postoperative Harris Hip scoring and VAS scoring were applied for evaluating hip function and pain at 1, 6 months and 5 years after operation respectively.

RESULTSAll patients were followed up for 48 to 73 months with an average of 60.4 months. Operative time, blood loss in DAA group was (78.30±5.08) min, (351.30±21.46) ml, respectively, in posterolateral approach group was (75.61±10.60) min, (362.20±26.15) ml, and no significant differences between two groups. Bed rest time in DAA group was (2.05±1.10) days, better than that of in posterolateral approach which was (3.30±1.35) days. No significant differences were found between two groups in acetabular abduction and stem shaft angle at 1 month after operation. There was no significant differences between two groups in HHS and VAS score at 1, 6 months and 5 years after operation. There was 1 case with injury of ascending branch of the lateral circumflex femoral artery, 1 case with great trochanter fracture and 1 case with superficial infection in DAA group, 1 case with dislocation in posterolateral group. No prosthesis loosening occurred in two groups.

CONCLUSIONSBoth DAA and posterolateral approach are effective in treating femoral head necrosis staged Ficat III or IV, and could obtain excellent outcomes. However, DAA seemed to has disadvantage in learing curve compared posteriolateral approach in complex cases.
