Objective To evaluate the safety and feasibility of hysteroscopy in the treatment of endogenous type cesarean section scar pregnancy (CSP). Methods Clinical data of 58 cases of CSP from August 2012 to February 2014 in our hospital were analyzed retrospectively.Thirty-one cases were treated by hysteroscopy,while 27 cases were treated by laparoscopy.The intraoperative blood loss,operation time,postoperative hospital stay,postoperative drainage of uterine cavity,β-hCG level resolution time and time to menstruous restoration were compared between the two groups. Results The intraoperative blood loss,operation time,length of hospitalization after operation,and time to menstruous restoration were statistically lower in the hysteroscopy group than those in the laparoscopy group [(109 ±59)ml vs.(143 ±63)ml,t =-2.121 ,P =0.038;(43.7 ±17.5)min vs.(100.8 ±18.8)min,t =-1 1 .974,P =0.000;(3.8 ±0.7)d vs.(4.5 ±0.6)d,t =-4.057,P =0.000;(43.8 ±3.9)d vs.(45.9 ±3.8)d,t =-2.070,P =0.043].There were no significant differences in postoperative drainage of uterine cavity and β-hCG level resolution time between the two groups [(22.1 ±2.8)ml vs.(23.6 ±3.2)ml,t =-1 .904,P =0.062;(20.5 ±7.7)d vs.(22.9 ±9.3)d,t =-1 .075,P =0.287]. Conclusion Hysteroscopy has advantages of less intraoperative blood loss,shorter hospitalization time and quicker recovery in the treatment of endogenous type CSP.

In the practice tache of medical studnets,carrying out bed side teaching and clinical rounds work,training the clinical basic skill,the thinking mode and the clinical performance ability can greatly improve the medical students' clinical ability.

We take some measures of teaching reform about Andrology in reproductive medical speciality,including the teaching outline,the content,books,the method and means.These measures of teaching reform meet the need of teaching and help to enhance the effect of teaching.

OBJECTIVE To study the safe methods of used disposal medical supplies to provide scientific results of decision-making for the health administration. METHODS Using the methods of "standard prevention", "isolated transformation", and "unit calculation", the disposable medical supplies were safely treated in a completely-closed and entirely-programmed way without disinfecting or damaging. The efficacy of the methods was evaluated. RESULTS Form 2006 to 2007, the distribution of disposable medical supplies was 13 306.12 kg and 14 046.00kg and the retrieved quantity was 13 306.00 kg and 14 041.00kg. The improved methods of quantification solved the problem existing in distribution and retrieving of the disposable medical supplies. The safety and convenience of the whole process had been greatly improved. CONCLUSIONS Compared with destroying shapes, disinfecting and "face to face" exchange methods, the methods of using "standard prevention", "isolated transformation" and "unit calculation" are safer, more economic, and more effective.

Licorice seedlings were taken as experimental materials, an experiment was conducted to study the effects of exogenous sucrose on growth and active ingredient content of licorice seedlings under NaCl stress conditions. The results of this study showed that under salt stress conditions, after adding a certain concentration of exogenous sucrose, the licorice seedlings day of relative growth rate was increasing, and this stress can be a significant weakening effect, indicating that exogenous sucrose salt stress-relieving effect. The total flavonoids and phenylalanine ammonia lyase (PAL) activity were significantly increased, the exogenous sucrose can mitigated the seedling roots under salt stress, the licorice flavonoid content in the enhanced growth was largely due to the activity of PAL an increased, when the concentration of exogenous sucrose wae 10 mmol x L(-1), PAL activity reaching a maximum, when the concentration of exogenous sucrose was 15 mmol x L(-1), PAL activity turned into a downward trend, the results indicating that this mitigation has concentration effect. After applying different concentrations of exogenous sugar, the contents of liquiritin changes with the change of flavonoids content was similar. After applying different concentrations of exogenous sucrose, the content of licorice acid under salt stress was higher than the levels were not reached during salt stress, the impact of exogenous sucrose concentration gradient of licorice acid accumulation was not obvious.

Objective:To investigate a potential role of Toll-like receptor 4(TLR4),a pathogen pattern recognition receptor, in the early phase of severely burned rats. Methods: Rats burn model(30% of total body surface area[TBSA], III grade) were established with vapor at 108°C for 8 seconds. Rats were sacrificed before and 2,5,12,24,48 and 72 h after burning, and the spleen specimens and peripheral blood samples were harvested. TLR4 mRNA and TNF-α mRNA expression in splenocyte was measured by reverse-transcription PCR (RT-PCR); the expression of TLR4 protein were measured by Western bloting; the endothelial toxicity concentration in plasma was detected by limulus lysate test. Results: It was found that the expression of TLR4 mRNA, TNF-α mRNA, TLR4 protein, and the level of ET were significantly increased in burned group compared with normal control group. The expression of TLR4 mRNA and protein peaked at 8 h after burning, the expession of TNF-α mRNA peaked at 12 h,and the level of ET peaked at 8 h after burning; the peak values of them were (3.66±0.51),(2.27±0.19), (1.65±0.23), and (11.68±2.63) Eu/ml,respectively,all significantly higher than those of the control group(P<0.01 or P< 0.05). The expression of TLR4 mRNA showed a positive correlation with that of ET and TNF-α mRNA(r=0.811,0.462, P< 0.01). Conclusion: Severe burn can cause endotoxemia and upregulate the expression of TLR4 and TNF-α in splenocytes. The up-regulation of TLR4 might participate in the pathological procedure of excessive inflammation.

OBJECTIVE: To establish a LC-MS method for simultaneous determination of 5 compounds (astragaloside IV, danshensu, protocatechualdehyde, ginsenosides Rg1 and Rb1) in Qishenyiqi Dropping Pills. METHODS: The chromatographic separation was carried out at 30°C on a Wonda Sil C18 column (4.6 mm × 150 mm, 5 μm) eluted in a gradient program. The mobile phase consisted of water containing 10 mmol · L-1 ammonium formate and 0.2% formic acid-acrtonitrile containing 0.2% formic acid. The mass spectra were obtained by Agilent 6410 triple quad mass spectrometer with electrospray ionization source in negative ion mode. RESULTS: The linear ranges for astragaloside IV, danshensu, protocatechualdehyde, ginsenosides Rg1 and Rb1 were 10.72-536.0, 89.10-4 455, 1.337-66.87, 22.60-1 130 and 23.55-1 177 ng · mL-1, respectively. The average recoveries ranged between 98%-102%. CONCLUSION: The established method is convenient, sensitive and accurate. It can be used for the determination of the contents of astragaloside IV, danshensu, protocatechualdehyde, ginsenosides Rg1 and Rb1 in Qishenyiqi Dropping Pills for quality control.
