To investigate the effects of Yiniao Recipe, a compound traditional Chinese herbal medicine, on contents of serum antidiuretic hormone, and plasma cyclic adenosine monophosphate and cyclic guanosine monophosphate in rats with kidney-yang deficiency.

Objective To investigate the function of acid pocket in reflux esophagitis. Methods The 15 healthy controls and 24 reflux esophagitis patients were identified by reflux disease questionnaire (RDQ) and gastric endoscopy. The location of subjects' lower esophageal sphincter (LES) was determined by 4 channel esophageal manometry system. Then a single-channel pH electrode was positioned 1 cm below the distal border of the LES to monitor fasting pH for half an hour. After a standard meal, the pH was continuously measured for two hours. Then the electrode was moved to 5 cm above the proximal border of the LES to monitor the dynamic pH for 24 h.Results Acid pocket was found in 16 cases of reflux esophagitis patients(66.67%) and 10 cases of healthy individuals (10/15). Acid pocket occurred earlier in reflux esophagitis group than healthy controls [11.00(4.25-17.00) min vs 30.00(15.50-54.25) min, P＜0.05], and the average pH value was lower [1.84(1.59-2. 19) vs 2.32 (1.96-2.71), P＜0.05]. There was no statistic difference in mean pH value of gastroesophageal junction and the duration of acid pocket before the meal.Conclusion There is abnormal acid reflux in reflux esophagitis patients, and acid pocket with earlier occurrence and lower pH value may relevant to esophageal mucosal impairment.

Objective To follow-up the patients with successful posterior segment intraocular foreign body removal.Methods Medical records of consecutive cases with posterior segment intraocular foreign body that were successfully removed between June 2005 and June 2008 were retrospectively reviewed.Twenty-three patients(23 eyes)were included in the series.Results Followed up 3-36 months All the patients underwent pars plana vitrectomy for posterior segment intraocular foreign body removsl,4 patients (4 eyes)experienced rhegmatogenous retinal detachments that were managed with good long-term visual outcomes.Conclusions Rhegmatogenous retinal detachments may occur following successful removal of posterior segment intraocular foreign body in several months after initial management.These rhegmatogenous retinal detachments can be successfully managed with a variety of methods,depending upon the extent and location of the detachments and causative break.Therefore,it is clinically important to perform a long-term follow-up in patients after successful posterior segment intraocular foreign body removal.

OBJECTIVE:To provide reference for rational use of antibiotics in the clinic. METHODS:In retrospective study, the distribution,composition and drug resistance of pathogens in our hospital during Jan.-Dec. in 2015 were analyzed statistically. RESULTS:In 2015,a total of 9401 specimens were collected in microbiology laboratory of our hospital;pathogens were detect-ed in 1743 specimens with positive rate of 18.54%;1591 strains of pathogens were isolated,mainly from sputum (59.77%), urine (14.775) and blood sample (8.93%). Totally 347 strains of Gram-positive bacteria(21.81%),991 strains of Gram-negative bacteria (62.29%),253 strains of fungus (15.90%)were detected. Top 4 pathogens in the list of amount were Escherichia coli, Klebsiella pneumoniae,Pseudomonas aeruginosa and Staphylococcus aureus. S. aureus,Streptococcus pneumoniae and Staphylo-coccus haemolyticus were sensitive to vancomycin,linezolid and sodium fusidate,with resistance rate of 0;resistance rates of them to erythromycin were more than 65%. The resistance rate of S. aureus to penicillin was more than 95%,and S. haemolyticus showed high resistance rate to common antibiotics. Drug resistances of E. coli,K. pneumoniae and P. aeruginosa to carbapenems were all lower than 15%,and they were sensitive to polymyxin with resistance rate of 0. Resistance rate of E. coli to quinolones was more than 50%. CONCLUSIONS:The main pathogens are Gram-negative bacteria in our hospital,drug resistance of them are not satisfactory. Drugs most sensitive to main pathogens include vancomycin,linezolid,carbapenems,etc. The inspection of patho-gen drug resistance characteristics should be strengthened,and antibiotics should be selected rationally and normatively according to the results of drug sensitivity test.

Percutaneous vertebroplasty has many advantages such as minimal trauma, simple mode of operation, rapid and correct therapeutic effect, high safety, and wide indications. Therefore it has been generally paid close attention and accepted. Percutaneous vertebroplasty has conspicuous curative effect, especially in vertebral compression fracture. Polymethyl methacrylate is the most used filling materials at present; There is not significant difference between unipedicular and bipedicular vertebroplasty; Using vertebral body venography and appropriate dense bone cement can reduce leakage of bone cement; Bolster for self-replacement can rebound vertebral body height, and balloon kyphoplasty and sky bone expander kyphoplasty can be avoided; In order to reduce refracture of vertebral body, anti-osteoporosis drugs should be used in the treatment of percutaneous vertebroplasty.

Objective To investigate the synergistic regulation of KDM3B and JMJD1C in leukemia. Methods The expression level of JMJD1C and KDM3B were analyzed in multiple acute myeloid leukemia (AML) cell lines. AML cell lines NB4 and HL-60 were treated with Daminozide, followed by determination of H3K9 mono-methylation and di-methylation. AML cell lines NB4 and HL-60 were treated with Daminozide, ATRA (retinoid acid All-trans), C Vitamin and the expression of KDM3B and JMJD1C were detected by real-time quantitative PCR. Results The expression level of KDM3B and JMJD1C in the AML cell lines was negatively correlated. In NB4 and HL-60 cells treated by daminozide, H3K9 mono-methylation and di- methylation level showed a rising trend in these two cell groups. After treatment of NB4 cells with the 3 reagents, the level of mRNA of KDM3B was down-regulated while the level of mRNA of JMJD1C was up-regulated. In HL-60 cells treated by daminozide, the mRNA level of KDM3B was up-regulated and the mRNA level of JMJD1C was down-regulated. Conclusion The expression of KDM3B and JMJD1C is negatively correlated in patients with AML.

0.05). CONCLUSION The PCNA labeling index may reflect the proliferating condition of NIP, but does not have relationship with NIP recurrence. And the role of p27 in the development of NIP needs more investigation.
