Objective To explore the diagnosis and treatment of adrenal black adenoma . Methods From June 2002 to July 2014, 7 patients with adrenal tumors were treated with retroperitoneal laparoscopic partial adrenalectomy in our hospital .During the operation all the patients were placed in healthy lateral decubitus position .Three trocars were introduced into the lumbar region:below the 12th rib along the anterior and posterior axillary lines , and 2 cm beyond superior iliac spine on the middle axillary line .The retroperitoneal space was established with homemade balloon-expanding devices .Afterwards , the tumors were removed by using a harmonic scalpel. Results All the tumors were resected completely .The average operation time was 60 min (range, 34-90 min) and the average blood loss in the operation was 70 ml (range, 20 -200 ml) without blood transfusion.The drainage tubes were removed on the 3rd or 4th postoperative day and the patients were discharged on the 6th or 7th postoperative day .They were pathologically diagnosed as adrenal black adenoma . Two patients manifested the Cushing ’ s syndrome and 3 patients showed hypertension , all of which were recovered to normal postoperatively .No recurrence or metastasis was noted during a follow-up for 12-24 months (mean, 18 months). Conclusions Adrenal black adenoma, without specific clinical features, is a rare kind of adrenocortical adenoma .The confirmative diagnosis depends on pathological results .Retroperitoneal laparoscopic surgery is a minimally invasive, safe and effective technique for adrenal black adenoma , which provides favorable prognosis .

Objective To compare the effects of different surgical methods for the recovery of elderly patients with acute cholecystitis and provide reference for its clinical treatment. Methods 60 Patients aged 65 years or older undergoing laparoscopic cholecystectomy for acute cholecystitis between January 2010 and December 2013 were selected from the database. The comparison group comprised 76 patients from the same age-group who underwent open cholecystectomy for acute cholecystitis. Then the curative effects of two groups were compared and analyzed. Results 76 patients underwent laparoscopic surgery and 60 had open surgery. The demographic data and co-morbidities were compared between the two groups. The postoperative hospital stay was significantly shorter for patients undergoing laparoscopy (P < 0.05). The overall complication rate was significantly lower for patients undergoing laparoscopy (P < 0.05). There was no statistical significant difference in the operating time and the bleeding among the operation. Conclusions Laparoscopic cholecystectomy is a safe procedure for acute cholecystitis in elderly patients , resulting in fewer complications and shorter hospital stay than open cholecystectomy. Laparoscopic cholecystectomy is worth in the clinical application.

Objective To investigate the carrying situation of nuc-mec A gene for different departments in the inpatient depart-ment and outpatient department to provide the data for the hospital infection control and reaching the target for preventing nosoco-mial infection and improving the cure rate.Methods The research subjects were divided into 4 groups:osteoarthropathy and hemi-plegia rehabilitation department group(A,44 cases),comprehensive surgical and hematology-oncology department group(B,32 ca-ses),cardiopulmonary department group(C,17 cases)and outpatient department group(D,35 cases).The group A,B and C were the persons in the inpatient department and the group D were the persons in the outpatient department,aged 30-84 years old.Na-sal swab samples were collected and the nuc-mec A gene was detected by the multi-channel real-time PCR.Results No person in the group A,B and C carried nuc gene and 1 case(2.86%)in the group D carried nuc gene.There were no statistically significant differ-ence among 4 groups(P >0.05);the carriers of mecA gene in the group A,B,C and D were 26,17,13 and 10 cases,the carrying rates were 59.10%,53.10%,76.50% and 28.60% respectively,the difference showed statistical significance(P <0.01),but which in the group A,B and C had no statistically significant difference(P >0.05);the carrying rate of nuc-mec A gene showed statistically significant differences between the patients and the medical staff(P <0.05),but which had no statistically significant differences be-tween the patients and the medical staff in each group(P >0.05).Conclusion nuc-mec A gene generally exists in the inpatient de-partment and the carrying rate of nuc-mec A gene is relatively lower,which indicates that the inpatient department needs to pay at-tention to the prevention and treatment of pathogenic bacteria,especially the de-clonization in the hemiplegia rehabilitation and car-diopulmonary departments for avoiding cross-infection among different departments.

Objective To investigate the carriage of nuc-mecA gene among different altitudes in high humidity district,provid-ed guiding data for prevention of staphylococcus aureus and drug-resistant bacteria,standardizing the usage for antibiotics. Methods The nose swabs were collected in different altitudes:1 000 m,1 200 m and 1 400 m,nuc-mecAgene was confirmed by multi-channel real-time PCR.Results The carrier of nuc gene in the noses were 4.878%,2.899% and 7.143%,in 1 000 m,1 200 m and 1 400 m respectively,and there were no statistical significant among the altitudes (P>0.05).The carrier of mecA gene were 14.634%,31.884% and 41.837% in the 1 000 m,1 200 m and 1 400 m respectively,the difference showed statistical significe (P<0.05).The carrying rate of mecA gene showed statistically significant differences between 1 000 m and 1 200 m (P<0.05),and showed statistically significant differences between 1 000 m and 1 400 m (P<0.01)also.The carrier of nuc-mecA gene were 0%,1.449% and 3.061% in 1 000 m,1 200 m and 1 400 m respectively,there were no statis-tical significant (P>0.05).Conclusion The carrier of mecA gene in noses was increased with the increasing of the altitude. The residents who living at higher altitude should keep the colonization sites of pathogens clean,and needed timely medical when got sick,shouldn’t abuse the antibiotics without authorization.Medical staff should rational use of antibiotic drugs,a-voided overusing of antibiotics and overtreatment.

5srRNA was isolated and purified from the reticulocytes of rabbit. It labeled with ~(125)I, then incubated with mouse myeloma cells (SP2/0). By autoradiography it was observed that ~(125)I-SsrRNA could pass into the nuclei of the cells. In a separate experiment, it showed that the incorporation rate of ~3H-TdR into nuclei of SP2/0 after incubation with 5srRNA was decreased as compared with that f control group, hence the result indicates that 5srRNA inhibits DNA synthesis of the SP2/0 cells and it seems to play a role in the regulation of gene expression through its hybridization with DNA sequences of the SP2/0 cells. Thus it is likely that 5srRNA might act as "erythroid denucleation factor".

The present study reported that 5srRNA from reticulocytes of rabbit could pass into the nucleus of mouse myeloma cells SP2/0,and in the mean time DNA synthesis and cells division were markedly suppressed. In a separate experiment, the rRNA was extracted from embryonic liver and erythrocytes of rabbit or rat and analysed by agarose electrophoresis method. The result indicated that the amount of 5srRNA in various period of the development of erythrocyte is changed along with denucleation process. Thus it is likely that 5srRNA of mammalian erythrocyte plays a role in reversing malignant phenotype of tumor cells and promoting denucleation of mammalian erythrocyte through inhibiting DNA synthesis.
