Objective To explore the application value of detection of Mycoplasma,Chlamydia and anti-sperm antibodies for male infertility.Methods Culture method,immune chromatography,and enzyme linked immunosorbent assay were adopted for the detection of Mycoplasma,Chlamydia,and anti-sperm antibodies respectively in 102 cases of infertile males and 42 cases fertile males.And the routine semen analysis was proceed as well.All the subjects were divided into 4 groups according to the detection re-sults:simple Mycoplasma or/and Chlamydia positive group(71 cases),simple anti-sperm antibodies positive group(21 cases),My-coplasma and Chlamydia or/and anti-sperm antibodies positive group(8 cases),Mycoplasma,Chlamydia and anti-sperm antibodies negative group(44 cases).The main indexes of semen routine were compared among 4 groups.Results The positive rates of Myco-plasma,Chlamydia and anti-sperm antibodies in infertile males were significantly higher than those of fertile males (P <0.05).The sperm densities,activity rates,activity of simple Mycoplasma or/and Chlamydia positive group,simple anti-sperm antibodies posi-tive group,and Mycoplasma and Chlamydia or /and anti-sperm antibodies positive group were significantly lower than the nega-tive group,while the sperm malformation rates,liquefaction times,white blood cell counts of the three groups were significantly higher than the negative group(P <0.05 ).Conclusion Mycoplasma,Chlamydia infection and anti-sperm antibodies production have significant effect on the indexes of semen,which cause decline in semen quality and the occurrence of male infertility.

Objective To evaluate the effects of rheumatoid arthritis treated with modified Duhuo-Jisheng decoction and western conventional treatment. Methods 120 patients with heumatoid arthritis of our hospital from January 2010 to 2013 August were recruited and randomly divided into a treatment group and a control group, 60 patients in each group. The control group was treated with oral intake of Methotrexate, Sulfasalazine and Meloxicam in acute stage and oral intake of diclofenc in stable stage, while the treatment group was further added modified Duhuo-Jisheng decoction on the basis of the control group. TCM symptom score, arthritis symptom score, symptomatic relief time, ESR, CRP, RF were observed after 3 months’ treatment.

AIM: This study was designed to investigate the protective role of hypobaric hypoxic pretreatment (HHPT) on hippocampal neurons in Babl/c inbred mice. METHODS: HHPT was produced by simulating a 7 000 m high altitude 2.5 h/d for 3 d. At 36 h after last time decompression, three subgroups consisted of both the control and pretreatment mice were subjected to the 12 000 m high altitude hypobaric hypoxia for 4 h, the severe ischemia produced by bilateral common carotid artery occlusion for 18 min, and the severe ischemia/hypoxia produced by permanently ligation of right lateral common carotid artery followed by a 8 000 m high altitude hypobaric hypoxia for 4 h, respectively. The extents of protection to hippocampal CA1 neurons by HHPT were evaluated by accounting the number of intact neurons between HHPT and control group. RESULTS: The results indicated that HHPT protected hippocampal neurons against severe hypobaric hypoxia, severe ischemia, and ischemia combined with hypobaric hypoxia. CONCLUSION: Hypobaric hypoxic pretreatment induces a delayed protection to hippocampal neurons against hypoxic and ischemic injuries.

AIM: This study was designed to explore the differentially expressed genes between hypobaric hypoxic delayed preconditioning (HHDP) and normal mouse hippocampus. METHODS: HHDP was produced by treating the animals at a 7 000 m high altitude for 2.5 h/d for 3 d. At 36 h after last time decompression, total RNA was isolated from hippocampus. cDNA was synthesized and amplified by SMART PCR. cDNA libraries of differentially expressed gene between HHDP and control hippocampus were constructed. 452 clones from forward (subtracted control from preconditioning) cDNA library and 74 clones from backward (subtracted preconditioning from control) one were screened by reverse Northern hybridization. RESULTS: Screening with subtracted probes, hybridization signal of 85 gene fractions decreased and that of 217 gene fractions increased by more than 2 times in HHDP hippocampus compared with control. Screening with unsubtracted probe, hybridization signal of 44 gene fractions decreased and that of 135 gene fractions increased by more than 2 times in HHDP hippocampus compared with control. Some of the clones had been sequenced. Analysis and comparison with the data of GenBank were performed. The results showed that mouse cytochrome C oxidase subunit 1, NADH dehydrogenase subunit 1 and 6, deleted in split-hand/split-foot 1 region (DSS1) and cDNA corresponding to clone IMAGE: 5251089 of mice cDNA library were increased in hippocampus of HHDP mice. cDNA corresponding to clone IMAGE: 3593193, mus musculus adult male olfactory brain cDNA and mus musculus bladder RCB-0544 MBT-2 cDAN were decreased in hippocampus of HHDP mice. CONCLUSION: Many genes expresses differentially in hippocampus of mice during HHDP. This may be one of the molecular mechanisms of HHDP.

Objective To evaluate the therapeutic efficacy of gamma knife in treatment of primary trigeminal neuralgia Methods Retrospectively analysis of 120 cases with primary trigeminal neuralgia treated by gamma knife in our department From Jan. 2003 to Mar. 2008 were performed. All cases were treated with the 4 mm collimator and targeted at the proximal nerve at the root entry zone located by MRI. The target dose varied from 80 -90 Gy. Results After a follow-up of 20. 0 ±4. 5 months, complete relief of pain occurred in 69 patients (57. 5%), 50% -90% relief in 34 (28. 3%), relief less than 50% in 12(10.0%) but no relief in 5(4.2 %).The efficient rate was 95. 8% . The common complications include numbness, absence of corneal reflex. 83 patients (69. 2%) experienced temporal facial numbness and 14 patients (11. 7%) reported continuous numbness after treatment of the gamma knife. Conclusions Gamma knife radiosurgery is a minimally invasive technique for the treatment of primary trigeminal neuralgia with few complications.

Objective To evaluate the effect of pronator teres tendon reconstructing the forearm interosseous membrane(IOM)central band on restoring the longitudinal stability of the forearm after Essex-Lopresti injury.Methods A total of ten fresh-frozen adult cadaveric forearms were loaded axially through the humeral and the distal radius.Each forearm was tested as following six steps:radial head excision,radial head plus excision of triangular fibrocartilage complex(TFCC),radial head plus TFCC plus excision of IOM central band,reconstructing central band with pronator teres tendon,metallic radial head prosthesis replacement,central band reconstruction plus radial head prosthesis replacement.The difference of the load exerted to displace the radius to the proximal for 5 mm was compared at different steps by using single-factor analysis of variance.Then,the effect of each step on restoring the forearm longitudinal stability of the forearmwas evaluated.Results There was statistical difference upon load for the radial displacement to the proximal for 5 mm in all six steps,ie,(74.51±15.17)N,(49.23±6.14)N,(17.83±4.73)N,(27.40±3.56)N,(140.25±25.39)Nand(164.21±28.26)N,respectively(P<0.01).With migration of the radius to proximal for 5 mm,the load for pronator teres reconstruction was 55.66% of radial head plus TFCC,and the load for pronator teres reconstruction plus radial head prosthesis replacement was 559.31% of IOM reconstruction step and 333.56% of radial head excision.Conclusions Reconstruction of the central band with pronator teres tendon is insufficient to restore the longitudinal stability of the forearm after Essex-Lopresti injury.Reconstruction of the central band in combination with metallic radial head prosthesis replacement are beneficial to restoring the longitudinal stability of the forearm.
