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.

Objective To observe the ultrastructure changes of brain of the late trimester of fetal rats via transumbilical vein injection using contrast-enhanced ultrasonography.Methods The forty pregnant rats in the late trimester were divided into four experimental groups randomly.After being successfully punctured in the umbilical vein,two fetus was randomly chosen from maternal uterus with injection contrast agent SonoVue or normal saline solution(20 fetus/each group).Group A as control group with injection of normal saline solution(120 μl/kg);group B as low dose group with injection of SonoVue 0.014 mg/kg(120μl/kg,0.118 ng/ml);group C as media dose group with injection of SonoVue 0.14 mg/kg(120 μd/kg,1.18mg/ml)and group D as high dose group with injection of SonoVue 1.4 mg/kg(120 μl/kg,11.8 mg/ml).After observing the process of every contrast-enhanced ultrasonographic examination,tissue slices of brain of these fetus were made for electronmicroscope investigation.Results ①There was no enhancement in the fetus and placenta in group A.Enhancement couldn't be clearly seen in group B because of fast wash-out contrast agent.On the contrary,the fetus and placenta enhancement in turn could be seen in group C and group D.Enhancement never be seen in maternal uterus and uterine outside.②There was no significant difference of ultrastructure changes of the fetal brain tissues in group A and group B with electronmicroscope.Different degree rough endoplasmic reticulum enlargement,mitochondria swelling,endothelial cell injury,glycogen deposition and vacuolization in the brain cells were found in group C and group D,and the value of contrast between the two groups was significantly different(P＜0.05).Conclusions It is decreasd gradually effects to perform transumbilical vein contrast enhanced ultrasonography with reducing gradually dose for the late trimester of fetal rats,but enhancement has been invisible in the low dose group.

Objective To evaluate the safety and feasibility of laparoscopic right hemi-hepatectomy for hepatolithiasis.Methods The clinical data of 3 patients who underwent laparoscopic right hemi-hepatectomy were analyzed retrospectively.Results In 2 patients the operation was performed successfully.The operative time was 340 min and 300 min,and the intraoperative blood loss was 800 ml and 400 ml.There was no need for blood transfusion.There was a small amount of bile leakage (30-60 ml/day) in these 2 patients.The postoperative hospital stay was 9 d and 11 d.The third patient was converted to open surgery because of profuse bleeding.All the 3 patients recovered well from surgery.Conclusions Total laparoscopic right hemi-hepatectomy for hepatolithiasis was safe and feasible.

Objective To evaluate the function and synchronization of left atrial in patients with chronic heart failure(CHF) by two dimensional-speckle tracking imaging (2D-STI) and real-time threedimensional echocardiography(RT-3DE).Methods Thirty-two healthy controls and twenty-nine patients with CHF were studied.The mean strain and strain rate during systole,early and late of diastole(mSs,mSe and mSa,mSRs,mSRe and mSRa) were measured at each left atrial wall by 2D-STI.From the volume-time curve of RT-3DE workstation,the maximum volume (LAVmax),the minimum volume(LAVmin),the volume before contraction(LAVp) of left atrial were acquired.Accordingly,the total,passive and active ejection fraction could be calculated.The synchronization parameters derived from 2D-STI and RT-3DE were the dispersion of time to peak strain and time to the minimum volume (T-SD and Tmsv-16-SD).The index of volume and time were corrected by the body surface area and interval of R-R,respectively.The correlation were analysed betwee them.Results () Comparing between two groups,the mSs,mSe and mSa were shortened and the mSRs,mSRe and mSRa were slower in CHF group (P ＜ 0.05).② All the index of volume were gradually increasing from control to CHF group,but the LATEF,LAPEF and LAAEF were just the reverse,with all parameters had significant difference between two groups (P ＜0.05).③ The synchronization parameters were significantly higher from control to CHF group by the two kinds of skills (P ＜0.05).Comparing with 2D-STI,the indexes of synchronization were bigger and the asynchronization rate of CHF group were higher by RT-3DE.④The indexes of synchronization had a negative correlation with the strain rate and the ejection fraction,but had a positive correlation with the index of volume.Conclusions The function of left atrial are reduced in patients of CHF,there are asynchronization.2D-STI and RT 3DE may paly important roles in the evaluation of function and synchronization of left atrial.The relevance ratio of the left atrial asynchronization are higher from the RT-3DE than 2D-STI.

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 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.
