Objective To compare intramedullary nail (IN) and dynamic hip screw (DHS) regarding their effects on hip abduction following fixation of intertrochanteric fractures.Methods From January 2008 to December 2015,310 patients with intertrochanteric firacture were treated at our department.They were divided into 2 groups depending on the manner of treatment.198 patients (71 males and 127 females) were subjected to intramedullary nailing,with an average age of 74.7 ± 5.6 years;there were 50 cases of 31-A 1,134 ones of 3 1-A2 and 14 ones of 3 1-A3 according to the AO classification.112 patients (35 males and 77 females) were subjected to dynamic hip screwing,with an average age of 74.1 ± 6.7 years;there were 24 cases of 31-A1,78 ones of 31-A2 and 10 ones of 31-A3.The 2 groups were compared in terms of time for weight-bearing ambulation and stand on one leg,gait,pelvic tilt,range of hip active abduction,muscle strength of the abductor and hip function at the final follow-up.Results Of this series,284 patients were followed up for 1.5 to 8.5 years (average,3.6 years) and 26 patients died.The IN group achieved significantly better outcomes in terms of time for weight-bearing ambulation (37.6 ±4.9 d),time for stand on one leg (60.1 ± 9.5 d),cases of normal gait and normal pelvic tilt (171 and 179),muscle strength of the abductor (62.3 ±4.4 N · m),and range of hip active abduction than the DHS group (53.0 ±8.4 d;71.0 ± 12.0 d;67 and 85;56.6 ± 3.3 N · m,respectively) (P ＜ 0.05).There was no significant difference between the 2 groups in the hip function at the final follow-up(91.4％ versus 84.5％ in the excellent and good rate)(P ＞ 0.05).Conclusion Compared with dynamic hip screwing,intramedullary nailing has a limited effect on hip abduction so that the patients may benefit from quicker functional recovery and faster improvement in quality of life.

Objective To evaluate the clinical diagnostic value of nucleic acid amplification (TB- RNA),bacteriophage-based assay,3D culture and smear on the detection of Mycobacteria tuberculosis.Methods 291 clinical sample including 110 sputum,54 thoracic fluid,37 throat swab,31 bronchial fluid,13 cerebrospinal fluid,12 urine,8 lymph fluid and 20 others (pericardial effusion,feces, blood and abdominal fluid) and gynecological specimen (including 6 leucorrhoea and menstrual blood) were analyzed by these four methods.Results Among the 291 clinical samples,the positive rate of mycobacteria tuberculosis for TB-RNA,bacteriophage-based assay,3D culture and smear were 37.1%,28.9%,27.5% and 10.3%.The sensitivity and specificity of the TB-RNA,bacteriophage-based assay,3D culture and smear were 54.3% & 100%,41.7% & 88.9%,31.7% & 93.5% and 14.6% & 98.9%,respectively.Conclusions TB-RNA is an effective clinical diagnostic method for Mycobacteria tuberculosis.Although the sensitivity of smear is poorer than others,it is a universal testing method in clinical laboratory due to low cost.The positive rate of mycobacteria tuberculosis for 3D culture is lower than that of bacteriophage-based assay and TB-RNA.Although the time to result for 3D culture might last for few weeks,the isolates can be used for drug resistance screening and bacterial identification.

It has gradually become a consensus in the industry that the traditional Chinese medicine gypsum should be decocted first, but the understanding of decocting method is not completely unified in the works of doctors since ancient times, and there are occasional disputes about whether it is necessary to decocting first. In this study, the phase determination, physical and chemical characterization, qualitative and quantitative analysis of inorganic and organic components of the decoctions of herbal pairs and the whole prescription Maxingshigan decoction with gypsum as the center, and the pre-decoctions and co-decoctions of them were carried out to explore the scientific connotation of the pre-decoctions of gypsum. Results show that decoction phases were different between the co-decoctions and pre-decoctions of licorice-gypsum (Gancao-Shigao, GC-SG), ephedra-gypsum (Mahuang-Shigao, MH-SG) and almond-gypsum (Xingren-Shigao, XR-SG). The results of the micromorphology, particle size and zeta potential of herbal pairs and prescription (Quanfang, QF) showed that the supramolecular particles in pre-decoctions were smaller, more uniform and more stable than the co-decoctions. The results of organic components analysis showed that different cooking methods did not change the organic composition and content. ICP-OES results showed that the content of inorganic components in pre-decoctions was higher than in co-decoctions for the same boiling time of gypsum. The IR results showed that the pre-decoctions had stronger chemical functional group effect than the co-decoctions. To sum up, compared with the co-decoction, the pre-decoction of gypsum has different phase state and chemical composition interaction, and the difference of inorganic composition is an important material basis affecting the change of phase state compared with the co-decoction. It indicates that the material basis of traditional Chinese medicine decoction is indeed different whether gypsum is decocted first or not, which can provide a basis for the clinical application of decocted gypsum.

OBJECTIVETo investigate the interventional effect of comprehensive behaviour psychotherapy on the ejaculatory latency of premature ejaculation (PE) patients, sexual satisfaction of sexual partners, as well as its influence on the results of clinical treatment.

METHODSNinety PE patients were randomly divided into a psychological intervention group (n = 45) and a control group (n = 45). Both groups were given medicine therapy, and the former also received comprehensive behaviour psychotherapy for 6 weeks. All the patients were assessed with the Chinese index of sexual function for PE and ejaculatory latency in the vagina, and the clinical efficacy was compared between the two groups.

RESULTSBefore treatment, the ejaculatory latency in the vagina was (0.69 +/- 0.25) min and (0.71 +/- 0.19) min respectively in the intervention and the control groups, as compared with (5.87 +/- 0.59) min and (4.76 +/- 0.54) min before treatment, with significant difference (P < 0.01). In the intervention group, the scores in the control of ejaculatory reflex, the sexual satisfaction of the patients and their sexual partners and anxiety or depress in sexual activity in CIPE were higher than in the control group, with significant difference between the two groups (t = 2.12, 2.31, 2.01, 2.24, P < 0.05). The difference in the SAS score after therapy was of significance (P < 0.01). A month after treatment, the effectivity rates of the two groups were 82.9% and 30% respectively, and the difference was significant (P < .01).

CONCLUSIONComprehensive behaviour psychotherapy obviously adds to the clinical efficacy of drugs in the treatment of PE.

The purposes of this study was to determine the effects of recombinant human interleukin-10 (rhIL-10) on proliferation of vascular smooth muscle cells (VSMCs) stimulated by advanced glycation end products (AGE) and neointima hyperplasia after rat carotid arterial injury. Rat aortic VSMCs were cultured and treated with rhIL-10 or AGE respectively, and then co-treated with rhIL-10 and AGE. Proliferation of VSMCs was quantified by colormetric assay. Cell cycle analysis was performed by flow cytomertry. Sprague-Dawley rats were treated with recombinant human IL-10 (rhIL-10) for 3 d after carotid arteries injury. The ratio of neointima to media area at the site of arterial injury was measured 28 d after balloon injury. The p44/42 MAPK activity was evaluated by the immunoblotting technique using anti-p44/42 phospho-MAPK antibody. Compared to control, AGE stimulated VSMCs proliferation. rhIL-10 alone had no effect on VSMCs growth. With AGE stimulation, rhIL-10, at dose as low as 10 ng/ml, inhibited VSMCs growth (P<0.05). The cell number in G(0)/G(1) phase of AGE and rhIL-10 co-treatment group was higher than that of AGE treatment alone (P<0.01) by flow cytometry analysis. Compared with the control group of neointima hyperplasia in rats, the ratio of neointima to media area of recombinant human IL-10 group was reduced by 45% (P<0.01). The p44/42 MAPK activity was significantly enhanced by AGE. The AGE effects were opposed by rhIL-10. The anti-inflammatory cytokine rhIL-10 inhibits AGE-induced VSMCs proliferation. Recombinant human IL-10 also inhibited neointima hyperplasia after carotid artery injury in rats. The results suggest the possibility that recombinant human IL-10, as a potential therapeutic approach, prevents neointimal hyperplasia.

OBJECTIVETo explore the prediction of the site for microsurgical vasoepididymostomy (VE) in the treatment of epididymal obstructive azoospermia (OA).

METHODSThis study involved 56 infertile men with confirmed OA whose obstruction was suspected to be in the epididymis. Based on their medical history and results of preoperative physical examination and ultrasonography, we predicted the sites for VE. We performed surgical scrotal exploration for the status of epididymal obstruction, conducted palpation and microscopic observation for the epididymal tubules to be anastomosed, and finally decided on the sites for VE by making sure of the presence of motile sperm in the epididymal fluid of the patients. After surgery, we followed up the patients for the rate of pregnancy.

RESULTSAll the patients received bilateral scrotal ultrasonography and surgical scrotal exploration, totaling 112 procedures, including 98 VE procedures. The accuracy rate of the predicted sites for VE was 80.5% (153/190) by medical history and physical examination, 80.3% (90/112) based on the results of ultrasonography, and 87.4% (90/103) according to the first selected epididymal tubules. Of the 28 patients followed up for more than 12 months, motile sperm were found in 19 (67.9% ) at 2 to 12 months and spontaneous pregnancies were achieved in 10 (35.7%), all with the anastomotic sites in the corpus or cauda.

CONCLUSIONMedical history and physical examination contribute to the selection of anastomotic sites and non-invasive scrotal ultrasonography is effective and practical for positioning epididymal obstruction. The epididymal tubules with motile sperm for anastomosis could be easily obtained from the most dilated ones in indurated epididymides.

Previous studies proposed that the synergistic effect of fibroblast growth factor-21 (FGF-21) and insulin may be due to the improvement of insulin sensitivity by FGF-21. However, there is no experimental evidence to support this. This study was designed to elucidate the mechanism of synergistic effect of FGF-21 and insulin in the regulation of glucose metabolism. The synergistic effect of FGF-21 and insulin on regulating glucose metabolism was demonstrated by investigating the glucose absorption rate by insulin resistance HepG2 cell model and the blood glucose chances in type 2 diabetic db/db mice after treatments with different concentrations of FGF-21 or/and insulin; The synergistic metabolism was revealed through detecting GLUT1 and GLUT4 transcription levels in the liver by real-time PCR method. The experimental results showed that FGF-21 and insulin have a synergistic effect on the regulation of glucose metabolism. The results of real-time PCR showed that the effective dose of FGF-21 could up-regulate the transcription level of GLUT1 in a dose-dependent manner, but had no effect on the transcription level of GLUT4. Insulin (4 u) alone could up-regulate the transcription level of GLUT4, yet had no effect on that of GLUT1. Ineffective dose 0.1 mg kg(-1) FGF-21 alone could not change the transcription level of GLUT1 or GLUT4. However, when the ineffective dose 0.1 mg x kg(-1) FGF-21 was used in combination with insulin (4 u) significantly increased the transcription levels of both GLUT1 and GLUT4, the transcription level of GLUT1 was similar to that treated with 5 time concentration of FGF-21 alone; the transcription level of GLUT4 is higher than that treated with insulin (4 u) alone. In summary, in the presence of FGF-21, insulin increases the sensitivity of FGF-21 through enhancing GLUT1 transcription. Vice versa, FGF-21 increases the sensitivity of insulin by stimulating GLUT4 transcription in the presence of insulin. FGF-21 and insulin exert a synergistic effect on glucose metabolism through mutual sensitization.
