OBJECTIVETo study the effects of using Compound Danshen Injection (CDI) and low molecular weight heparin (LMWH) on early severe preeclampsia women.

METHODSRetrospective analysis was carried out in 95 patients with early severe preeclampsia from October 2008 to January 2011. They were assigned to 3 groups based on anticoagulant drugs. The routine therapy of magnesium sulfate (MgSO4) was given to the MgSO4 group (40 cases); the MgSO4 + CDI was given to those in the CDI group (23 cases), the MgSO4 + LMWH group was given to those in the LMWH group (32 cases). The general data of all patients were collected to analyze their effects on labor, postpartum hemorrhage, reasons for terminating the pregnancy, and maternal complications.

RESULTS(1) The average gestational week (weeks) of terminating the pregnancy was 31.7 +/- 1.9 in the MgSO4 group, 33.0 +/- 1.8 in the CDI group, and 32.8 +/- 1.7 in the LMWH group. The average weight of newborn babies (g) was 1 450.5 +/- 402.3 in the MgSO4 group, 1 582.2 +/- 332.5 in the CDI group, and 1 590.0 +/- 340.1 in the LMWH group. There was no obviously difference in the average gestational weeks or the average weight of newborn babies among the three groups. (2) The way of terminating the pregnancy was uterine-incision delivery. The main reasons for operation were sequenced as maternal complications, unsatisfied control of the blood pressure, and fetal distress. (3) The maternal complications in the three groups were sequenced as renal failure (12 cases), placental abruption (9 cases), hemolysis, increased liver enzymes and low platelet (HELLP) syndrome (8 cases). Sixteen (40.0%) had complications in the MgSO4 group, 12 (52.2%) in the CDI group, and 15 (46.9%) in the LMWH group. No statistic difference existed among the 3 groups.

CONCLUSIONSLMWH and CDI were helpful to improving the therapeutic effects of severe preeclampsia patients. They did not increase adverse drug reactions. They seemingly had effects on prolonging the gestational week.

OBJECTIVETo investigate the frequency and type of PHEX gene mutations in children with X-linked hypophosphatemic rickets (XLH), the possible presence of mutational hot spots, and the relationship between genotype and clinical phenotype.

METHODSClinical data of 10 children with XLH was retrospectively reviewed. The relationship between gene mutation type and severity of XLH was evaluated.

RESULTSPHEX gene mutations were detected in all 10 children with XLH, including 6 cases of missense mutation, 2 cases of splice site mutation, 1 case of frameshift mutation, and 1 case of nonsense mutation. Two new mutations, c.2048T>C and IVS14+1delAG, were found. The type of PHEX gene mutation was not associated with the degree of short stature and leg deformity (P=0.571 and 0.467), and the mutation site was also not associated with the degree of short stature and leg deformity (P=0.400 and 1.000).

CONCLUSIONSMissense mutation is the most common type of PHEX gene mutation in children with XLH, and c.2048T>C and IVS14+1delAG are two new PHEX gene mutations. The type and site of PHEX gene mutation are not associated with the severity of XLH.

OBJECTIVESTo investigate the pathoanatomize histological and biochemical characteristics of benign prostatic hyperplasia (BPH) by use of old dogs with spontaneous BPH as animal models.

METHODSOld dogs aged 6 to 13 years were recruited after anus check, B-ultrasonic examination by recta spy and measurement under surgical exploration. Ten dogs with notable prostatic hyperplasia were used as models, and 6 with non-hyperplasia prostate as control. Serum testosterone (T), estrogen (E2), ACP and prostatic specific antigen (PSA) were analyzed, and prostates were checked histologically.

RESULTSProstate volume of the BPH group was significantly bigger than those of the control group, (14.7 +/- 2.3) and (13.8 +/- 1.9) cm3 vs (8.4 +/- 1.0) and (8.4 +/- 1.9) cm3, P < 0.01. Serum T [(14.3 +/- 2.9) vs (16.4 +/- 4.0) nmol/L] and E2 [(137.6 +/- 70.8) vs (164.4 +/- 82.0) pmol/L] were not different between the two groups (P > 0.05). ACP of the BPH group was higher than that of the control group [(6.63 +/- 2.76) vs (4.92 +/- 2.19) U/L], but the difference was not statistically significant (P > 0.05). There was significant difference between the BPH group and the control group in PSA level [(5.6 +/- 0.78) vs (3.1 +/- 0.54) microgram/L, P < 0.01]. The tissue slides of the BPH prostates showed hyperplasia with raised height of epithelium, and many long and offsetting mammillae in the gland cavity due to epithelium hyperplasia.

CONCLUSIONOld dogs with spontaneous BPH are useful animal models for the etiological and pharmacological researches of human BPH.

Background Macular edema following phacoemulsification with intraocular lens (IOL) implantation is a main factor to influent visual function.The administration of traditional medicine can relieve tissue edema,but its preventive and treatment efficacy on macular edema after phacoemulsification with IOL implantation remaines unclear.Objective This study was to investigate the protective effect of huoxuehuayu decoction on macula after phacoemulsification with IOL implantation.Methods A case-controlled observational study was designed.One hundred and eighty eyes of 150 patients with age-related cataract were randomized into operation group and operation + medicine group.Phacoemulsification with IOL implantation was performed in both groups,but huoxuehuayu decoction was orally administered for 14 days in operation+medicine group.The best corrected visual acuity,inflammatory reaction of the ocular anterior segment,and macular edema were recorded before operation and 1 week,2,4,6,8 and 12 weeks,and the central macular thickness was measured using optical coherence tomography.Results Twelve weeks after surgery,the ratio of visual acuity ≥ 1.0 was in significantly higher in operation+medition group than that of in operation group (x2 =1.066,P＞0.05).One week after surgery,the eyes of the aqueous flare were much nore in the operation group than that of operation+medicine group(x2 =9.341,P＜0.05).The thickness of the central fovea was significantly increased in both groups at 1 week,2,4,6,8 and 12 weeks after surgery,showing significant differences in comparison with preoperation (operation group:P ＜ 0.01 ; operation + medicine group:P ＜0.05).Macular edema occurred in 13 eyes in operation group during the following-up duration,including 11 eyes with thickened fovea and 2 eyes with cystoid macular edema.Maeular edema disappeared in 10 eyes 12 weeks later.In the operation+medition group,3 eyes happened macular edema,including thickened fovea in 2 eye and cystoid macular edema in 1 eye.Four to six weeks after surgery,macular edema disappeared in 3 eyes 12 weeks later.The fovea thickness in the operation+medicine group was statistically significantly lower from 2 through 8 weeks after surgery than that in the operation group(t=2.315,2.323,3.104,2.470,P＜0.05).Conclusions Oral administration of huoxuehuayu decoction is helpful for the restoration of the anterior ocular segment.Huoxuehuayu decoction can protect macula from the edema induced by phacoemulsification.

AIM: To investigate the protective effect of huoxuehuayu decoction on macula after phacoemulsification. Into A, B groups. The 80 eyes of A group were treated by conventional phacoemulsification; the patients (60 eyes) of B group were given huoxuehuayu decoction orally for two courses after phacoemulsification. Best-corrected visual acuity(BCVA), corneal and aqueous conditions ,thickness of macular central fovea and changes of macular retinal tissue in A, B groups were observed before surgery, 1 day; 1 week,2,4,6,8 weeks and 3 months after surgery. Was significantly higher than that of group A. One week after surgery the ratio of mild aqueous flare in group B was significantly lower than that of group A. The thickness of central fixation was significantly increased in both groups 1 week, 2, 4, 6, 8 weeks and 3 months after phacoemulsification; the difference between 2 to 8 weeks after surgery and pre-operation showed statistical significance in both groups. 11 eyes in A group had macular edema during 2 to 6 weeks after surgery, including 9 eyes with fovea thickened and 2 eyes with cystoid macular edema, and seven eyes' edema disappeared in 3 months. 2 eyes in B group had macular edema, including 1 eye fovea thickened and 1 eye cystoid macular edema, during 4 to 6 weeks after surgery, and the two eyes' edema disappeared 3 months after surgery. The fovea thickness in group B during 2 to 8 weeks after surgery was statistically lower than group A. Phacoemulsification.

Objective:To explore the role and mechanism of Forkhead box protein 3 (FoxP3)in biological behavior of gastric cancer (GC)cells.Methods:Invitro,the plasmid of FoxP3-shRNA was transfected into GC cells,and then the stably transfected cells were established by drug-screening and monoclone-selection.MTT assay was used to detect the growth and proliferation of GC cells.And cell cycle was detected by flow cytometry.MTT assay was used to measure the difference regarding sensitivity to chemotherapy drugs.Results:GC cell line which was stably transfected with FoxP3 gene,was established.GC cell line with up-regulation of FoxP3 gene,compared to the vector-transfected control,showed slower growth and proliferation rate,weaker ability of invasion (transmembrane cell counts:[203±42]cells/HPvs [891±100]cells/HP, P<0.05),and higher sensitivity to chemotherapy drugs(P<0.05).Conclusions:FoxP3 gene plays a role in inhibiting the growth of GC cells.

OBJECTIVETo observe effects of electroacupuncture of different frequencies on morphological changes of nervous tissues and electromyogram (EMG) of skeletal muscles in regeneration,so as to find more proper parameters of electroacupuncture.

METHODSThe nerve regeneration chamber was built after the sciatic nerve was transected, and acupuncture was given at "Huantiao" (GB 30) , "Zusanli" (ST 36) and "Sanyinjiao" (SP 6) at the affected side with different frequencies (5 Hz, 100 Hz), 30 min each time,once every other day, 3 time each week, for 20 weeks and a control group was set up for natural recovery. The nerve fibers were stained by silver dying and ultrastructures of nerve tissues were observed. EMG of gastrocnemius was determined by Biopac physiologic apparatus.

RESULTSElectroacupuncture could promote the recovery of form of nerve tissues after the transection of sciatic nerve and functions of de-innervated muscle tissues after lesion of sciatic nerve, and the therapeutic effect of electroacupuncture at 5 Hz was the best.

CONCLUSIONElectroacupuncture is an important way of promoting the regeneration of the lessoned peripheral nerve.

OBJECTIVETo investigate whether 5alpha-reductase inhibitor and dihydrotestosterone (DHT) play a role in spermatogenesis in male rats.

METHODSThirty-two male rats were divided into 4 groups (Groups C, T, F and FT). Group C received plant oil injection and oral starch perfusion, Group T testosterone undecanoate (TU, 20 mg/kg) injection and oral starch perfusion, Group F plant oil injection and oral Finasteride perfusion, and Group FT TU (20 mg/kg) injection and oral Finasteride perfusion. Data on serum T and DHT, sperm count, sperm mobility and reproductive function were collected and analysed.

RESULTS(1) 5alpha-reductase inhibitor, Finasteride and TU reduced the weight of the testis and epididymis in the experiment groups compared with the negative control (Group C), but TU increased the weight of the prostate while Finasteride decreased it compared with the positive control (Group T). TU combined with Finasteride could counteract the effect of the weight increase of the prostate, but not that of the testis. (2) Finasteride, or Finasteride combined with TU, reduced the DHT but increased the testosterone level in comparison with the control group. (3) Both Finasteride and TU could inhibit epididymal sperm count and reproductive function compared with the control, but the effect was less significant in Group FT than in Group F.

CONCLUSIONHigh dosages of 5alpha-reductase inhibitor, Finasteride, can suppress male reproductive function, but the inhibiting effect could be counteracted by administration of 5alpha-reductase inhibitor along with TU.

OBJECTIVEShen Yan Ling Tablet is an innovative compound of traditional Chinese medicine, scientifically prepared with Tripterygium wilfordii, Radix Astragali, and others, with precise efficacy on renal diseases and reduced adverse effects of Tripterygium wilfordii. Based on the Guiding Principles for New Drug Toxicity Research Before Clinical Application, we investigated the long-term toxicity of Shen Yan Ling Tablet and its effect on the reproductive function in rats.

METHODSAccording to the clinical therapeutic dose and the results of the acute toxicity test of Shen Yan Ling Tablet, we equally divided 80 rats (males and females half-and-half) into a low-dose (1.25 g/kg body wt), a medium-dose (2.50 g/kg body wt), a high-dose (5.00 g/kg body wt) and a control group. After a 3-month medication, we conducted standardized long-term toxicity tests and observed the effects of Shen Yan Ling on the serum sexual hormones and epididymal sperm count.

RESULTSAfter 3 months of treatment with Shen Yan Ling, no death occurred, the general status remained unchanged, and the parameters of blood cytology and biochemistry fluctuated within the normal range, without any significant changes (P > 0.05). Some blood parameters, RBC, WBC, HGB, AST and TBIL, showed statistic changes (P < 0.05), but with no clinical significance. There were no significant differences in the mass coefficients of the main organs between the medication and control groups. The high-dose group exhibited slight hepatic and pulmonary pathological changes and significantly reduced sperm counts in the epididymis, but no significant changes in serum sexual hormones (P < 0.05).

CONCLUSIONThree-month medication of Shen Yan Ling at 1.25 - 5.00 g/kg produced no significant accumulated toxicity on rats, but it had a negative effect on their reproductive function at a higher dose of > or = 5.00 g/kg.
