AIM: To study the infiltration of polymorphonuclear neutrophils ( PMNs ) after conjunctival flap covering in alkali-burned cornea.
●METHODS: Rabbit cornea alkali-burned model was made, then 50 rabbits were randomly divided into the experimental group ( n=25 ) and the control group ( n=25 ) . At the same time the surgery of conjunctival flap covering was given to rabbits of the experimental group. The condition developing of alkali-burned cornea was observed by slit lamp biomicroscopy, and took photos in two groups. The infiltration of PMNs was identified by hematoxylin eosin ( HE) staining in different periods.
●RESULTS:The quantity of PMNs increased on the 3d, reached the lower level on 7d, shown a peak on the 14d, then decreased gradually. PMNs level of the experimental group was significantly lower than that in the control group, and the difference of 3, 14 and 21d was significant (P<0. 05).
●CONCLUSION: During the wound healing process, alkali - burned cornea has close relation with the infiltration of PMNs. The treatment of conjunctival flap covering for the severe alkali-burned cornea was found to have good effect.

Objective To explore the clinical value of cardiac magnetic resonance imaging (CMRI) in assessment of right ventricular function in patients with pulmonary arterial hypertension (PAH).Methods The PubMed/MEDLINE,Wanfang data,CNKI (from January 2001 to April 2015) were searched.The search terms were pulmonary arterial hypertension,right ventricular function,and cardiac magnetic resonance imaging.An inclusion criterion was the patients suffering from PAH,and the healthy volunteers were served as controls.The study was designed as randomized controlled trial.All the subjects investigated had received CMRI.The end of the trial included right ventricular end diastolic volume (RVEDV),right ventricular end systolic volume (RVESV) and right ventricular ejection fraction (RVEF).Meta analysis was conducted by RevMan 5.0 software provided by Cochrane Collaboration,and the publication bias was analyzed by the funnel plot analysis.Results Five papers involving 381 patients met the criteria.It was showed by Meta-analysis that compared with healthy control group,RVEDV was increase in PAH group [weighted mean difference (WMD) =33.96,95％ confidence interval (95％CI) =20.80-47.12,P ＜ 0.000 01],RVESV was increased (WMD =41.91,95％ CI =29.63-54.19,P ＜ 0.0O0 01),and RVEF was decrease (WMD =-20.09,95％CI =-22.65 to-17.52,P ＜ 0.000 01).Conclusion CMRI can be used to evaluate the right ventricular function of patients with PAH,and it has important significance in the evaluation of right ventricular function in patients with PAH.

Objective To approach the effect of fluoride on the expression of thyroid peroxidase(TPO)activity and TPO mRNA in primary porcine thyrocytes.Methods Purified cultured porcine thyrocytes waft made into sodium fluoride model,and were divided according to the final concentration of NaF into 0(control group),40,80,160 mg/L.After exposed to NaF for 48 h,the morphology of the porcine thyrocytes was investigated with acridine orange staining method,TPO activity was measured with upgrade guaiacol method and RT-PCR method was used to detect the ratio of TPO/β-actin.Results The major changes included apoptotic bodies and cell fragments in the 80,160 mg/L groups under phase contrast microscope.With the increasing dose of fluoride.TPO activity,being(3.103±0.090),(1.944±0.025),(1.361±0.008),(0.668±0.026)U/L,respectively,had obviously lowered with a statistical significance compared between the groups(F=1563.864,P＜0.05).The TPO activity had a negative correlation with the dose of fluoride(r=-0.955,P＜0.05).With the dose of fluoride increasing,the expression of TPO mRNA had obviously lowered,being(0.947±0.013),(0.634±0.018),(0.448±0.028)and (0.210±0.009)with a statistical significance in group comparison(F=2713.855,P＜0.05).Conclusion Fluoride affects the thyroid via inhibiting TPO activity and expression of TPO mRNA.

Objective To compare the effects of oxycodone hydrochloride injection versus sufentanil for postoperative analgesia in patients undergoing laparoscopic cholecystectomy (LC) operation. Methods Sixty patients of both sexes , aged 18-65 yr , weighing 46-85 kg , scheduled for LC operation , were randomly divided into 2 groups (n = 30). Patient-controlled intravenous analgesia (PCIA) pump (oxycodone hydrochloride injection 20 mg or sufentanil 100 μg with physiological saline to 100 ml ) was used for postoperative analgesia five minutes before the end of operation. The first dose and bolus dose were both 5 ml , background infusion was 2 ml/h,lockout interval was 5 minute. The NRS score of rest and during movement at 1 ,6 and 24 h after operation,total oxycodone or sufentanil consumption in 24 h, requirement for rescue analgesic, the level of patient′s satisfaction , the adverse events were recorded. Results There was no significant difference in the NRS scores at rest and during movement , total oxycodone or sufentanil consumption in 24 h and postoperative nausea and vomiting (PONV) between the two groups. The patient’s satisfaction were significantly higher (P < 0.05), and the incidence of dizziness were significantly lower (P = 0.026) in group Q than in group S. Both groups were no requirement for rescue analgesic , no sleepiness , no itch , no retention of urine and other adverse reaction. Conclusion PCIA with oxycodone hydrochloride injection is safe and effective in reducing pain after LC operation, however the incidence of dizziness is lower and the level of patient’s satisfaction is higher with oxycodone hydrochloride than with sufentanil.

The applicator therapy is a unique method to treat infant diarrhea in traditional Chinese medicines and widely applied in clinical practice. Currently, many researchers have proved the rationality of the therapy based on the traditional Chinese medicine mechanism and on the data from clinical practice, but its action mechanism is uncertain at present. In this study, with the assistance of pediatric practitioners, the automated ribosomal intergenic-spacer analysis (ARISA) was adopted to study the effect of the adjuvant therapy with Dingguier umbilical paste on intestinal flora of diarrhea infants, in which Dingguier umbilical paste served as the adjuvant therapy in oral traditional Chinese medicines and fecal samples of infants with different diarrhea symptoms were collected and used as the study materials. The results showed that the adjuvant therapy had a significant effect on the shift of intestinal flora, which was associated with the decrease in the similarity difference to the normal control group and the increase in the number of operational taxonomic units (OTUs) shared with the normal control group. Additionally, adjuvant therapy with Dingguier umbilical paste also showed long action duration and increased OTUs number. These results indicated that Dingguier umbilical paste has the effect in restoring the micro-ecosystem of unbalanced intestinal bacteria. Intestinal flora may be one of major targets for the applicator therapy for the infant diarrhea, but not for the single oral traditional Chinese medicine for infant diarrhea.
