Objective To study basic thyroid stimulating hormone (bTSH) levels impact on outcomes of in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) in Qinghai.Methods Totally 282 cases with IVF cycles and 93 cases with ICSI cycles were studied prospectively,according to bTSH level,patients were divided into four groups.Reproduction rate,clinical pregnancy rate,miscarriage rate and live birth rate were studied among four groups.Results (1) In 375 cases with IVF/ICSI cycles,bTSH was positively correlated with abortion rate (r=0.42,P=0.04),but live birth rate and growing rate showed negative correlations with bTSH (r=-0.42,-0.28; P=0.04,0.03).bTSH and the number of eggs,the number of fertilized eggs,the number of embryos,biochemical pregnancy rate,and clinical pregnancy rate were no significant correlation (all P＞0.05).(2) Among women at group of ≤1.7,＞1.7 and ≤2.5,＞2.5 and ≤3.5,＞3.5 mU/L,the implantation rates were 28.7％,27.3％,37.7％ and 19.2％,live birth rates were 80.9％,75.0％,82.7％,and 59.8％,abortion rates were 19.0％,15.0％,16.7％,40.1％; they all showed significant difference (all P＜0.05).Abortion rate in women with high bTSH level was higher than that of women with lower bTSH level,however implantation rate,live birth rate in women with high bTSH level were lower.Conclusion When bTSH level is ＞3.5 mU/L,the abortion rate were increased,but live birth rate,rate of implantation were decreased.

Objective To evaluate the clinical effects of total knee arthroplasty (TKA) in treatment of severe adults Kashin-Beck disease (KBD). Methods Sixteen cases of KBD patients underwent TKA in Shaanxi Provincial People's Hospital, including 2 males (2 knees) and 14 females (17 knees), aged 41 to 56 years, mean (56.38 ± 6.40) years, left knee in 8 cases and right knee in 11 cases, knee varus in 15 cases and valgus knees in 4 cases. Visual Analogue Scale/Score (VAS), Hospital for Special Surgery (HSS) scores, knee range of motion, varus deformity and postoperative complications were observed before and after TKA. Results In this group of TKA patients, the levels of VAS scores in pre-total knee arthroplasty (pre-TKA), 2 weeks post-total knee arthroplasty (post-TKA), 3 months post-TKA, and at the end of the follow-up were 7.51 ± 1.00, 3.56 ± 1.29, 1.83 ± 1.40 and 1.10 ± 0.87, respectively. The level of VAS scores in 2 weeks post-TKA was significantly lower than that in pre-TKA (P<0.01), and the VAS levels were continued to decrease in post-TKA (all P< 0.01). Total HSS score at the end of the follow-up post-TKA was 78.60 ± 5.30, which was significantly higher than that in pre-TKA (43.59 ± 10.08, t=19.21, P< 0.01). At the end of the follow-up post-TKA, in addition to the muscle strength, the levels of pain, knee function, activity, flexion deformity and stability (25.94 ± 4.17, 15.88 ± 3.70, 14.09 ± 1.03, 6.79 ± 2.25, 8.58 ± 1.30) were significantly higher than those in pre-TKA (11.56 ± 5.39, 7.56 ± 1.75, 9.86 ± 3.85, 3.05 ± 3.22, 5.00 ± 3.07, t= 16.00, 8.32, 6.43, 7.07, 6.95, all P< 0.01). At the end of follow-up post-TKA, the knee degree of extension [(3.05 ± 2.71)°] was significantly lower than that in pre-TKA [(15.11 ± 11.30)°, t= -5.40, P< 0.01], the knee degree of flexion [(115.79 ± 9.65)°] was significantly higher than that in pre-TKA [(93.95 ± 22.40)°, t=6.02, P< 0.01), the degree of varus [(2.40 ± 2.40)° ] and valgus [(3.75 ± 2.50)° ] deformity was significantly lower than those in pre-TKA [(11.33 ± 10.43)°, (18.00 ± 5.72)°, t = - 4.15, - 3.61, all P< 0.05]. One patient was diagnosed as knee tuberculosis in 6 months post-TKA. There was no complication in this group of patients. Conclusion The TKA in severe adults knee of KBD can significantly reduce knee pain, improve knee function, correct joint deformities and improve quality of life in patients, and shows good clinical results.

OBJECTIVE: To investigate hidden hearing loss in tinnitus patients with normal audiograms by means of auditory brainstem response (ABR) and explore the origin of tinnitus. METHOD: Pure tone thresholds, ABR thresholds, amplitude of wave I and wave V of ABR were analyzed in 40 tinnitus patients and 15 controls. RESULT: There was no significantly difference in pure tone thresholds and ABR thresholds between those tinnitus patients and controls while a reduced amplitude of wave I and normal amplitude of wave V of ABR in the tinnitus patients became evident. CONCLUSION Tinnitus patients with normal audiograms have hidden hearing loss at the level of primary auditory nerve and the generation of tinnitus is likely attributed to a homeostatic response of neurons in brainstem.
