OBJECTIVETo explore the mechanisms of Qianjing Decoction in the treatment of oligoasthenospermia (OAS).

METHODSWe randomly divided 100 SPF male rats into five groups of equal number: normal, model, Huangjingzanyu, levocarnitine, and Qiangjing. OAS models were established in the animals followed by intragastrical administration of normal saline, ornidazole, Huangjingzanyu Capsules (200 mg per kg body weight per day), levocarnitine (100 mg per kg body weight per day), and Qianjing Decoction (10 g per kg body weight per day), respectively, qd, for 4 successive weeks. Then, we detected the concentration and motility of the epididymal sperm, obtained the contents of superoxide dismutase (SOD), malonaldehyde (MDA), glutathione peroxidase (GSH-Px), lactate dehydrogenase (LDH), α-glucosidase, and fructose in the epididymis, and determined the mRNA expressions of nuclear factor erythroid 2-related factor 2 (Nrf2) and succinate dehydrogenase (SDH) in the epididymal tissue of the rats by real-time PCR.

RESULTSThe concentration and motility of the epididymal sperm in the model, Huangjingzanyu, levocarnitine, and Qianging groups were (35.34 ± 4.22) x 10(6)/ml and (40.04 ± 7.05)%, (48.12 ± 5.56) x 10(6)/ml and (62.46 ± 7.12)%, (47.14 ± 4.87) x 10(6)/ml and (63.23 ± 6.34)%, and (50.25 ± 5.08) x 10(6)/ml and (66.34 ± 7.58)%, respectively, all significantly lower than in the normal group ([53.05 ± 4.55] x 10(6)/ml and [70.20 ± 8.54]%) (P < 0.05), but remarkably higher in the Huangjingzanyu, levocarnitine, and Qiangjing groups than in the model rats (P < 0.05). Compared with the thinned epididymal lumen walls, decreased sperm count, and disorderly and loose arrangement of the lumens in the OAS models, the rats in the Huangjingzanyu, levocarnitine, and Qiangjing groups showed evidently thicker epididymal lumen walls, with the lumens full of sperm cells and arranged regularly and compactly, similar to those of the normal rats. The levels of SOD and GSH-Px were significantly lower but that of MDA markedly higher in the model rats ([84.12 ± 23.25], [10.56 ± 3.02], and [14.04 ± 2.06] nmol/mg) than in the normal group ([110.04 ± 19.56], [17.25 ± 3.56], and [8.87 ± 1.35] nmol/mg) (P < 0.05), while the former two indexes remarkably higher and the latter one significantly lower in the animals treated with Qiangjing Decoction ([120.56 ± 23.68], [16.34 ± 3.12], and [8.45 ± 1.56] nmol/mg), Huangjingzanyu Capsules ([115.34 ± 21.35], [15.23 ± 3.67], and [8.33 ± 1.54] nmol/mg), and levocarnitine ([116.67 ± 22.67], [15.35 ± 3.45], and [8.05 ± 1.78] nmol/mg) than in the models (P < 0.05). The levels of fructose, LDH and α-glucosidase were decreased markedly in the OAS models ([100.22 ± 12.12] mg/[ ml x g], [322 ± 46.13] U/[ ml x g], and [10.48 ± 2.33] U/[ml x g]) as compared with the normal rats ([128.12 ± 13.45] mg/[ml x g], [428 ± 35.12] U/[ml x g], and [15.34 ± 3.12] U/[ ml x g]) (P < 0.05), remarkably higher in the rats treated with Qiangjing ([130.23 ± 13.67] mg/[ml x g] [455 ± 51.50] U/[ml x g], and [18.56 ± 4.67] U/[ml x g]), Huangjingzanyu ([124.16 ± 14.02] mg/[ml x g], [ 419 ± 43.14] U/[ml x g], and [17.64 ± 4.08] U/[ml x g]), and levocarnitine ([123.34 ± 14.02] mg/[ml x g], [430 ± 31.80] U/ [ml x g], and [16.85 ± 5.55] U/[ml x g]) than in the models (P < 0.05). The Nrf2 mRNA expression was significantly reduced in the models as compared with the normal rats (P < 0.05) but remarkably increased in the Huangingzanyu, Qiangjing and levocarnitine groups as compared with the model and normal animals (P < 0.05). The SDH mRNA expression was significantly lower in the model than in the normal rats (P < 0.05) but markedly elevated in the Huangjingzanyu, Qiangjing and levocarnitine groups as compared with the model and normal animals (P < 0.05), remarkably higher in the Qiangjing than in the Huangjingzanyu group (P < 0.05).

CONCLUSIONOrnidazole induces OAS in rats, which is closely associated with excessive oxidation and energy metabolism dysfunction. Qiangjing Decoction can improve and even reverse ornidazole-induced OAS in rats as well as improve the ultrastructure of their testicular and epididymal tissues. Antioxidation and improvement of energy metabolism are probably the action mechanisms of Qiangjing Decoction in the treatment of OAS.

OBJECTIVETo observe the effect of Zhibai Dihuang Decoction (ZDD) on mRNA and protein expressions of transient receptor potential family vanilloid subtype 1 (TRPV1) and transient receptor potential family vanilloid subtype 5 (TRPV5) in Ureaplasma urealyticum (UU)-infected rat semens and spermatogenic cells, and to explore the pathomechanism of UU-infected infertility and the intervention of ZDD.

METHODSTotally 45 were randomly selected from 60 4-5 months old SD rats. UU testicular infected animal models were set up after bladder inoculation of UU suspension. The remaining 15 rats were simultaneously injected with normal saline as a normal control group. After a successful modeling, UU infected model rats were randomly divided into the model group, the azithromycin group, and the ZDD group, 15 in each group. Rats in the ZDD group were administered with ZDD at the daily dose of 1 g/kg by gastrogavage. Rats in the azithromycin group were administered with azithromycin suspension at the daily dose of 0. 105 mg/kg by gastrogavage. Equal volume of normal saline was administered to rats in the normal control group and the model group. All medication was performed once daily for 21 successive days. Testes and epididymis were extracted after rats were killed and UU positive rates were compared among all groups. Sperm cells were separated using a mechanical separation technique. Sperm motility parameters were detected using color sperm motion detection system. mRNA and protein expressions of TRPV1 and TRPV5 in spermatogenic cells were determined by real-time quantitative PCR and Western blot.

RESULTSThe UU positive rate was obviously higher in the model group than in the normal control group [(86.7% (13/15 cases) vs. 0] P < 0.05). It was lower in the ZDD group [33.3% (5/15 cases)] and the azithromycin group [26.7% (4/15 cases)] than in the model group (P < 0.05). Compared with the normal control group, class A and B sperms were reduced, the linear velocity and the average velocity were significantly lowered, mRNA and protein expressions of TRPV1 and TRPV5 in spermated genic cells significantly decreased in the model group (P < 0.05). Compared with the model group, class A and B sperms were increased, linear and curve velocities and the average velocity were significantly elevated, mRNA and protein expressions of TRPV1 and TRPV5 significantly increased in the ZDD group and the azithromycin group (P < 0.05, P < 0.01). Compared with azithromycin group, class A and B sperms were increased, the linear velocity and the average velocity were significantly elevated, mRNA and protein expressions of TRPV1 and TRPV5 significantly increased in the ZDD group (P < 0.05, P < 0.01).

CONCLUSIONZDD could fight against UU infection and elevate semen quality, which might be associated with up-regulating mRNA and protein expressions of TRPV1 and TRPV5 in spermatogenic cells.

OBJECTIVETo study the effect of Zhibai Dihuang Pill (ZBDHP) on urokinase-type plasminogen activator (uPA) and sperm quality in ureaplasma urealyticum (Uu) infection infertile patients.

METHODSRecruited were 80 infertility patients with Uu infection at Andriatrics Clinics and Department of Reproduction, including 130 cases of positive Uu semen and 50 cases of negative Uu semen. Patients with positive Uu semen were randomly assigned to the observation group (72 cases) and the control group (58 cases) according to the visit sequence. All patients took antibiotics for 2 weeks. Patients in the observation group additionally took ZBDHP, 6 g each time, twice daily. Those in the control group additionally took Vit E (100 mg each time, twice per day) and ATP (40 mg each time, twice per day). The therapeutic course for all was 90 days. Semen parameters and uPA contents of the sperm membrane were detected and comparatively analyzed.

RESULTSThe sperm membrane uPA content, the sperm motility, the sperm viability, and the percentage of normal morphology sperm in Uu positive infected patients were lower than those in Uu negative infected patients with statistical difference (P < 0.05), but with no significant difference in the sperm density between the two groups (P > 0.05). There was no statistical difference in pre-treatment sperm membrane uPA contents and sperm parameters between the two groups (P > 0.05). Compared with before treatment in the same group, the sperm membrane uPA content, the sperm motility, the sperm viability, and the percentage of normal morphology sperm obviously increased in the two groups with statistical difference (P < 0.05). After treatment, the sperm membrane uPA content increased more obviously in the observation group, with statistical difference when compared with the control group (P < 0.05).

CONCLUSIONSInfection with Uu leads to decreased uPA content of sperm membrance and the sperm motility. ZBDHP could effectively treat Uu infected infertility possibly through fighting against Uu damaged sperm membrane and make the sperm membrane uPA content return to normal, and elevate the fertilizability of sperms.

OBJECTIVETo investigate the mid-term outcome of operation for thoracolumbar tuberculosis. METHODS : Twenty-eight patiens with thoracolumbar tuberculosis underwent one stage anterior debridement,interbody fusion with bone graft and posterior pedicle screw internal fixation treatment from July 2006 to July 2011. There were 17 males and 11 females. Total 17 patients had nerve injuries ,including 6 cases of grade B, 5 cases of grade C, 6 cases of grade D according to Frankel classification. The poisoning symptoms of tuberculosis and recovery of spinal function were observed. The bone fusion and recovery of [umbar function were evaluated.

RESULTSAll the patients were followed up ,and the duration ranged from 39 to 85 months (mean 57 months). The clinical symptoms were controlled gradually, and the thoracolumbar back pain was alleviated after operation. Among the 17 patients with complications of nerve injuries, 3 patients were improved from preoperative grade B to postoperative grade D, 3 patients were improved from preoperative grade B to postopertive E, 5 patients with preoperative grade C and 6 patients with preoperative D were almostly recovered to normal after operation. According to JOA scoring system for curative effect evaluation, the excellent and good rate at the 3rd month, the 1st year, the 3rd year and the 5th year after operation were 67.86% ,82.14% ,85.71% ,89.29% and 91.30% respectively. The results at the 6th month and the 1st year had no statistical differences compared to the results at the 3rd month (P > 0.05); but the results at the 3rd year and the 5th year were better than that at 3 months after operation (P < 0.05); and the results between 3 yesrs and 5 years after operation had no statistical differences (P < O.05). The degeneration of adjacent segments were evaluated according to the California University (Universith of California at Los Angeles , UCLA) score. The degeneration rate was 53.57% (15/28) at the 3rd year after surgery, which was better than that before surgery. Twenty-three patients were followed up for 5 years ,and the degeneration rate was 86.96% (20/23) ,which was better than those of before surgery and 3 years after surgery.

CONCLUSIONThe surgical treatment for thoracolumbar spinal tuberculosis can achieve the thorough debridement, reconstruction of spinal stability, recovery of lumbar function and promote the functional recovery of the spinal cord, which is an effective method of treatment. However, the mid term follow-up showed that more severe degenerative changes were found in the postoperative adjacent segment.

Background Normal adult optic disc rim width follows inferior ≥ superior ≥ nasal ≥ temporal (ISNT) rule.Analysis of the optic disc structural parameters with Heidelberg retina tomograph (HRT) can understand whether ISNT principle is suitable to other optic disc structure parameters.Objective This study was to investigate the characteristics of optic nerve head structure parameters in normal Chinese adults.Methods The parents of twins who participated Guangzhou Twin Eye Study were enrolled in Zhongshan Ophthalmic Center from 2006 June to 2011 August.All subjects received the routine eye examinations,including visual acuity,slit lamp microscope,direct ophthalmoscope examination,auto-refraction examination and HRT Ⅲ examination.All data from the right eyes were collected and analyzed.HRT values from different quadrants of optical nerve head were compared with one-way analysis of variance,and the multiple comparison between quadrants was carried out by Bonferroni test.The differences of optical nerve head parameters in different gender were analyzed using independent sample t test and Bland-Altman test.Results In this study,1672 eyes of 1672 subjects were included,with the 759 male and 913 female persons and average age of (41.8±5.3)years.No significant differences were seen in the disc area (DA)between the superior and inferior,as well as the nasal and temporal quadrants among the subjects (P＞0.05).In addition,there were not significantly different in the rim area (RA) between the superior and nasal disc as well as the rim volume (RV) among the inferior,superior and nasal disc (P＞O.05).However,significant differences were found in the cup area (CA),cup/disk area ratio (C/DAR),cup volume (CV),mean cupdepth (MCD),maximum cup depth (MxCD),height variation contour (HVC),cup shape measure (CSM),mean retinal nerve fiber layer thickness (mRNFLT) and retinal nerve fiber layer cross section area (RNFLcsa) among the different quadrants (P＜0.001).The local differences from only DA and RA complied with an ordination of the ISNT rule.The values of DA,CA,C/DAR,CV,MCD,MxCD from male individuals were higher,but those of the RV,HVC,mRNFLT RNFLcsa were lower in comparison with female individuals.Nevertheless,all the differences were ＜ 0.1 with a maximal mean difference in DA and CA (both 0.07 mm2).Conclusions The optical nerve head configurations measured by HRT have different distributing characteristics in four quadrants in normal adults.Most parameters show the higher values in the inferior and superior than those in nasal and temporal of disc,but DA and RA meet ISNT rule.The differences of most parameters between male and female subjects can be ignored.
