Despite the immense achievement in the field of IVF in recent years, many patients still suffer from recurrent implantation failure. Therefore, much attention has been drawn to its etiology and treatment. Chromosomal abnormality, sperm DNA damage, zona hardening, and inappropriate culture conditions are important factors that lead to recurrent implantation failure. Results of studies suggest that preimplantation genetic screening does not improve the rate of implantation or live birth. Comparative genomic hybridization array and single nucleotide polymorphism array could offer a more comprehensive screening of chromosomes. Assisted hatching may help to solve the problem of zona hardening in some situations. Co-culture and blastocyst transfer could be conducive to the improvement of the rates of implantation and pregnancy. Cytoplasmic transfer may give a solution to ooplasmic composition anomalies.

Inhaled nitric oxide has been identified as a potent method for curing acute respiratory distress syndrome,high brood pressure and some illnesses related to the lung,but the high cost limits its application.The present study investigates the reason of the high cost of inhaled nitric oxide in the current application,and gives some advices on solving them by using pulsed arc discharge in clean air,reducing the price of nitrogen oxides analyzer and being compatible with the present ventilators.The perspective of inhaled nitric oxide was viewed as well.

Stenotrophomonas maltophilia is among eight strain of broad resistance to antibacterial. It has been pay attention to global students, and is very difficulty in clinic treatment. Infection of Stenotrophomonas maltophilia is more familiar in ICU. Its test rate is 13.45%(62/461) in the study .The resistance character: IPM﹑CZO﹑CRO﹑AMP and MNO is highest(resistive rate 100%). ATM、GEN 、 KAN 、MEM 、CTX and PIP is much high(≧86.5%), LVX﹑GAT and FEP is high (=50%).Conclusion: Stenotrophomonas maltophilia should be monitored in the hospital. Used of antibacterial must be rational. Severe disinfection and isolation should been put in practice to the infected patients. CSL is very active antibacterial (active rate 90.6%) against Stenotrophomonas maltophilia in the study, and ought be selected headmost in treated its infection.

OBJECTIVE To study the characteristic of epidemiology of hospital infection among recipients after liver transplantation and to probe into its risk factors.METHODS Totally 193 cases were investigated.The infection group was compared with the non-infection group.Descriptive statistics and risk factor analysis were performed with SPSS11.0.RESULTS Forty nine cases took place infection.The infection rate was 25.4% and the death rate was 20.41%.15 cases(30.61%) happened 2 or 3 time infections.Mid-time of infection was 14d.Twenty six case(30.61%) infection occurred within 4 weeks and 25 cases(51.02%) were on June and July.Pulmonary infection(32.84%),wound infection(31.34%) and abdominal cavity infection(23.90%) were ranked in front.A total of 693 strains were isolated,and Gram-negative(G-) bacilli were 42.14%,Gram-positive(G+)cocci 35.30% and fungi were 22.66%.The three risk factors were obviously correlated with the infection(P

To investigate the mechanism of agarwood formation in Aquilaria sinensis induced by Lasiodiplodia theobromae, the fermentation liquor of L. theobromae was analyzed qualitatively and quantitatively by gas chromatography-mass spectrometry (GC-MS). JAs were detected in the fermentation liquor. The effect of the fermentation liquor on the abundance of sesquiterpenes in the callus of A. sinensis was analyzed by solid phase microextraction-gas chromatography-mass spectrometry (SPME-GC-MS). And the fermentation liquor stimulated alpha-guaiene, alpha-humulene and delta-guaiene biosynthesis in calli. It was inferred that L. theobromae produced JAs, which resulted in a significant increase of sesquiterpenes in A. sinensis.

This study aims to investigate the effect of total flavones of Fructus Chorspondiatis (TFFC) on the mRNA and protein expression of collagen type I and III of rat cardiac fibroblasts (CFs) induced by angiotensin II (Ang II), and explore its anti-myocardial fibrosis molecular mechanism. Neonatal rat CFs were prepared from Sprague-Dawley rats (1-3 d after birth). The expression of collagen type I and III mRNA and protein were measured by RT-PCR and Western blotting, respectively. The study showed that stimulation of neonatal rat CFs with 100 nmol.L-1 of Ang II for 72 h resulted in a significant increase of the expression of collagen type I and III mRNA and protein. The changes on the expression level were blocked by TFFC. The results demonstrated that TFFC can inhibit myocardial fibrosis induced by Ang II in rats, which is probably associated with the collagen type I and III mRNA and protein levels up-regulated by Ang II, and TFFC was shown to decrease the expression levels of collagen type I and III mRNA and protein.

Objective To evaluate the overall effect of transsphenoidal microsuegery for 23 patients with non-adenomas disease intrasellar region.Methods A toal of 23 patients with non-adenomas disease in- trasellar region,7 cases of Rathke's cleft cyst,3 cases of craniopharyngiomas,2 cases of meningiomas,2 ca- ses of pituitary tuberculous granuloma,5 cases of pituitary abscess,2 cases of empty sella,2 cases of chord- mas,were treated via sublabio-septo-sphenoidal microsurgery.Results There were among the 23 patients, groos total removal of the disease were achieved in 14 cases,subtotal removal in 7 cases,and partial removal in remain 2 cases.Diminished visual activity and visual field defects were improved in 13 cases.Menstrual disorder in all female cases and sexual disturbance in male were improved.There was no death in group. Conclusion Microsurgical technique via transsphenoidal approach is a safe and effective one for the treatment of patients with non-adenomas disease intrasellar region.

OBJECTIVETo study Chinese syndrome typing of acute hepatic failure (AHF) mice model by screening effective formulae.

METHODSLipoplysaccharides (LPS)/D-galactosamine (D-GaIN) was intraperitoneally injected to mice to establish the AHF mice model. Yinchenhao Decoction, Huanglian Jiedu Decoction, Buzhong Yiqi Decoction, and Xijiao Dihuang Decoction were administered to model mice respectively by gastrogavage. The behavior and the survival rate were monitored. The liver function and pathological changes of liver tissues were detected.

RESULTSIn all the tested classic recipes, the survival rate was elevated from 10% to 60% by administration of Xijiao Dihuang Decoction. Five h after modeling, the serum alanine aminotransferase (ALT) level was (183.95 +/- 52.00) U/L, and aspartate aminotransferase (AST) (235.70 +/- 34.03) U/L in Xijiao Di-huang Decoction Group, lower than those of the model control group, but with insignificant difference (ALT: 213.32 +/- 71.93 U/L; AST: 299.48 +/- 70.56 U/L, both P > 0.05). Xijiao Dihuang Decoction could obviously alleviate the liver injury.

CONCLUSIONSXijiao Dihuang Decoction was an effective formula for LPS/D-GaIN induced AHF model. According to syndrome typing through formula effect, heat toxin and blood stasis syndrome dominated in the LPS/D-GalN induced AHF mice model.

OBJECTIVETo observe and evaluate objectively the clinical effect of Guilong Tongluo Capsule (GTC) in treating chronic inflammatory demyelinating polyneuropathy (CIDP).

METHODSSixty CIDP patients were equally randomized into two groups. The treated group was administered with GTC and prednisone, while the control group with prednisone alone. Changes before and after 3-month treatment in terms of muscle force, functional and sensory disturbance of extremities, as well as scoring by Activity of Daily Living Scale (ADL) and electromyogram (EMG) for nerve conduction velocity were observed and compared.

RESULTSThe total effective rate gained in the treated group and the control group was 90.0% (27/30) and 70.0% (21/30) respectively, showing significant difference between them (chi2 = 14.82, P < 0.01). The improvement in the treated group was superior to the control group in muscle force of lower limb, motive and sensory function of extremities, ADL scores and motive function of ulnar nerve (P < 0.05, P < 0.01).

CONCLUSIONThe curative effect of GTC combined with prednisone in treating CIDP was better than that of prednisone alone.
