Objective To evaluate the efficacy of surgical retrieval of testicular spermatozoa,and to present the preliminary results of the retrieved testicular spermatozoa used in intracytoplasmic sperm injection (ICSI) for treatment of non obstructive azoospermic infertility. Methods Forty nine cases of non obstructive azoospermia underwent open testicular biopsy and diagnostic testicular sperm extraction (TESE).Those who had sperms in diagnostic TESE underwent ICSI at least 3 months later. Results Sperms were detected in diagnostic TESE in 12 cases (24.9%). The testicular volume,FSH level and testicular pathology did not accurately predict the presence or absence of sperm in testes.Seven (87.5%) of 8 cases had sperm in re TESE, which were used in their ICSI cycles,resulting in 3 clinical pregnancies. Conclusions The diagnostic TESE should be performed to determine the presence or absence of testicular spermatozoa in testicular failure before ICSI,and the surgically retrieved testicular spermatozoa can be adopted in ICSI for treatment of non obstructive azoospermic infertility.

Objective To investigate the clinical efficacy of heat-sensitive point moxibustion plus manipulative reduction in treating thoracic facet joint disorder. Method A single-blind randomized controlled trial was carried out. Eighty-two patients meeting the criteria were randomly allocated to an observation group of 42 cases and a control group of 40 cases. The observation group received heat-sensitive point moxibustion plus manipulative reduction and the control group, TDP plus manipulative reduction. Both groups were treated five times a week, five times as a course for a total of two courses (including the patients cured after less than two courses). The therapeutic effects were evaluated by using the McGill Pain Questionnaire the as the observation index, comparing pre-/post-treatment Pain Rating Index (PRI) scores, Visual Analogous Scale (VAS) scores and Present Pain Intensity (PPI) scores and referring to the Criteria of the Diagnosis of and the Therapeutic Effect on Syndromes in Traditional Chinese Medicine. Result After treatment, the PRI, VAS and PPI scores decreased significantly in both groups (P<0.01) and were lower in the observation group than in the control group (P<0.01). The cure rate was 57.1% (24/42) in the observation group, which was significantly higher than 27.5% in the control group (11/40,P<0.01). The total efficacy rate was 95.2% (40/42) in the observation group, which was significantly higher than 80.0% in the control group (32/40,P<0.01). Conclusion Heat-sensitive point moxibustion plus manipulative reduction has a very good therapeutic effect on thoracic facet joint disorder. The effect is significantly better than that in the control group.

Objective Diffusion tensor imaging(DTI)was used to explore the characteristics of white matter (WM)microstruc-ture lesion in patients with temporal lobe epilepsy(TLE)and hippocampal sclerosis(HS).Then we investigated the influence of the age of epilepsy onset and the course on WM changes.Methods DTI data were obtained in 30 TLE patients with HS and 23 age and sex-matched healthy controls.Thirteen patients had left HS (LHS)and seventeen had right HS (RHS).Between-group compari-sons of fractional anisotropy (FA)were carried out by using track-based spatial statistics (TBSS).In addition,FA in regions of in-terest (ROI)where white matter lesions had statistically significant difference was correlated with the age of onset and the course. Results Subjects in the LHS group,as compared to healthy controls,demonstrated these clusters of reduced FA:bilateral corona radiata,the left genu of corpus callosum,the right body and splenium of corpus callosum,the right posterior thalamic radiation,ex-ternal capsule and superior longitudinal fasciculus.White the subjects in the RHS group,the clusters of reduced FA are involving bi-lateral corpus callosum,corona radiata,posterior thalamic radiation,cingulum,superior longitudinal fasciculus,and the right ante-rior limb of internal capsule,the right retrolenticular part of internal capsule and external capsule.In LHS group,the FA of the left genu of corpus callosum was negatively correlated with the course,and the FA of the right anterior corona radiata was positively cor-related with the age of onset.In RHS group,the FA of the bilateral superior corona radiata was positively correlated with the course.Conclusion DTI detects extensive changes in TLE with HS that are not confined to temporal lobe.The age of epilepsy onset in LHS was correlated with the changes of anterior corona radiata,while the course and the WM change were not definitely linked to each other.
