Objective To investigate the current knowledge and attitudes towards people living with HIV/AIDS (PWHAs) in Chinese registered nurses (RNs) and describe the relationships between the nurses' HIV/AIDS related knowledge and attitudes towards PWHAs. Methods A cohort of 1350 RNs from 51 comprehensive hospitals in Hunan, China were studied over a 4-month period. A 3-stage random sampling method was used. Results The total correct rate in AIDS Knowledge Scale was 63.2%. Most nurses were good at conceptions of routes of AIDS infection and some basic characteristics, with more than 80% of the correct responses rate of relevant items. Their weakness was in the knowledge of some activities which would not transfer AIDS, such as "eating in a restaurant where the cook has AIDS may infect HIV", with less than 50% of the correct response rate of relevant items. As for attitudes, 94% of the nurses sympathized with HIV patients. About 82.7% of the nurses showed little sympathy to patients getting HIV by sexual promiscuity. Among all the AIDS related knowledge, nurses' conception of non-infectious activities was significantly related to their attitudes to HIV/AIDS.Conclusion Chinese nurses waster well about HIV/AIDS basic characteristics and the routes of infection, and most nurses sympathize with PWHAs. Their weakness is in the knowledge of non-HIV-infectious activities and they hold different attitudes to those patients getting HIV/AIDS in different ways. There are some barriers for Chinese nurses to take care of all patients equally. Professional development programs are urgently needed to remedy this situation including clarifying the nurses' misconceptions on AIDS related knowledge, developing non-judgmental professional attitudes, and using universal prevention measures when they take care of all patients.

Objective To investigate the mechanism of hypedipidemia on pancreas of rats by comparative proteomic analysis.Methods Ten male SD rats were randomly divided into two groups,the experimental group Was fed with high lipid forage and the control group Was fed with normal food.Pancreatic samples from the two groups were harvested six weeks later.Differential protein analysis Was performed using differential in-gel electrophoresis(DIGE),and characterizing the protein biomarkers using tandem mass spectrometry.Western blot Was used to confirm the expression of significantly changed proteins.Results Compared to the normal pancreas tissue,a total of 3 protein spot-features were found to be significantly increased and 11 significantly decreased in pancreatic samples with hyperlipidemia.Significantly increased proteins in hyperlipidemia pancreatic samples were arginaseⅡ,ribonuclease inhibitor and glyeine amidinotransferase,which increased by 2.19,1.82 and 1.12 fold,respectively.Significantly decreased proteins in hyperlipidemia group were tyrosyl-tRNA synthetase,alpha-amylase,triacylglycerol lipase,DJ-1protein,Cu,Zn superoxide dismutase,which dicreased by 2.48,2.37,1.85,1.73 and 1.65 folds,respectively.Western blot analysis revealed increased arginase Ⅱ levels and decreased alpha-amylase in pancreatic samples with hyperlipidemia.Conclusions Pancreas wag possibly injured by hyperlipidemia via increase of arginase Ⅱ.Decreased amylase and lipase may be the protection mechanism of pancreas.

Abstract: Objective　This article summarizes the clinical characteristics and diagnosis and treatment experience of an elderly patient infected with Omicron variant BA.5.1.3 of COVID-19 in Hainan Province. Methods　The clinical data and treatment of an elderly patient infected with Omicron variant BA.5.1.3 of COVID-19 admitted to Haikou designated hospital on August 15, 2022 were retrospectively analyzed. Results　A 107-year-old female patient was admitted to the hospital with "fever and cough for 1 day". Two of her family members have infected with COVID-19. The patient initially developed fever, accompanied by cough, expectoration, a little white sticky sputum, accompanied by sore throat, muscle pain, fatigue. Nucleic acid test was positive in throat swab, indicating Omicron variant BA.5.1.3 infection. The patient was diagnosed as mild COVID-19 and treated with antiviral therapy, Chinese medicine conditioning, anticoagulation, electrolyte disorder regulation and symptomatic treatment for 9 days. The patient's clinical symptoms were relieved, and she was cured and discharged after two negative nucleic acid tests. One week later, the patient recovered well. Conclusions　Omicron variant BA.5.1.3 is highly infectious, and comprehensive treatment such as antiviral treatment and traditional Chinese medicine treatment has achieved good efficacy. For elderly patients, attention should be paid to maintaining the stability of organ function and internal environment, which is helpful to improve the prognosis of patients.

Objective To compare the therapeutic efficacies of fire-needle acupuncture and Halometasone cream in treating sub-acute and chronic eczema. Method Totally 114 patients were divided into a treatment group and a control group. The treatment group was intervened by using fire-needle acupuncture, and the control group was by Halometasone cream. Itchy score and Eczema Area and Severity Index (EASI) were used for comparison before and after intervention. Result There were significant differences in comparing the markedly-effective rate and total effective rate between the fire-needle acupuncture group and the Halometasone control group according to the itchy score (P＜0.01). There were no significant differences in comparing the markedly-effective rate and total effective rate between the two groups according to EASI (P>0.05). Conclusion Fire-needle acupuncture is superior to Halometasone cream for acute and chronic eczema in relieving itch, action time and effect-sustaining duration.

Objective To investigate the clinical outcomes of minimally invasive percutaneous nephrolithotomy(MPCNL)in the treatment of lower caliceal calculi.Methods We retrospectively re- viewed the clinical outcomes and complications of 33 patients who underwent MPCNL for lower caliceal cal- culi from March 2001 to April 2005.The average diameter of the calculi was 2.8 cm.Single tract nephrosto- my was performed in all 33 cases;among them renal access was obtained through a middle calyx in 10 cases and a lower calyx in 23.Nine cases had F14 renal access;and 24 cases,F16.Results Of 33 cases,28 (85%)achieved stone-free at 1 session.A second-look was needed in 3 cases due to intraoperative bleed- ing;ESWL,in 1 case with residual,calculi;no treatment,in 1 case with residual calculi＜4 ram.The mean operative time was 93 min;mean blood loss was 113 ml;mean hospital stay was 11 d.Blood transfusion was needed in 1 patient who suffered from hepatic cirrhosis preoperatively;another experienced severe bleeding 7 d after operation and was cured with hyperselective spongia gelatinosa embolization of the renal artery.Fol- low-up was available in 19 cases for 2-48 months,and no recurrence of renal calculi was noted.Conclu- sions Minimally invasive percutaneous nepbrolithotomy has advantages of safety,less invasion,and easy re- covery for the treatment of lower caliceal calculi.

Objective To discuss the value and experience of the percutaneous vertebroplasty (PVP)in the treatment of vertebral body compression fracture(VCF)in aged osteoperosis.Methods PVP was performed in 44 cases with VCF including 28 with single vertebral compressed fracture,12 with double compressed fracture and four with triple compressed fracture,with 67 vertebrae,for clinical and radiologieal evaluation.Results The mean follow-up was 15 months(4-23 months).There could be seen immediate relief of pain in 40 cases,out-of-bed activities at operation day in 19 and out-of-bed activ- ities at second day after operation in 25.Postoperative X-ray showed uniformly distributed bone cement in the vertebral,without leakage.Conclusion PVP is a recommendable method for VCF,for it has ad- vantages of pain relief,vertebrae stabilization,minimal invasion and minor complications.

OBJECTIVETo investigate the treatment for traumatic intervertebrae disk herniation in cervical thoracic junction.

METHODSFrom 2003 to 2008, there were 10 patients with trautimatic intervertebral disk herniation in cervical thoracic junction, which included 6 males and 4 females, aged from 23 to 66 years (means 41.5 years). All of them were performed through the transforminal approach combined with internal fixation. After operation all patient underwent hyperbaric oxygen treatment. The function of spine was evaluated by JOA score system.

RESULTSAll patients were followed up for 8 to 16 months(means 13 months). All patients got recovery of spine function to some extent except one case with complete spine damaged. The JOA scores was improved from (8 +/- 3) before operation to (15 +/- 2) after operation.

CONCLUSIONEarly and effective treatment by transforminal operation could be helpful for the recovery of spine function.

OBJECTIVETo investigate the rationality and feasibility of primary closure of the common bile duct after choledochotomy for common bile duct calculi.

METHODSFrom January 1990 to June 2001, 386 patients with the evidence of stones in the common bile duct underwent choledochotomy. Among them, 215 received primary closure of the common bile duct (group A) and 171 T-tube drainage (group B). The patients with emergency operations were excluded. Intraoperative choledochoscopy or cholangiography was routinely performed to rule out the possibility of retained stones. The duct was meticulously stitched using 0/3 to 0/5 absorbent sutures for primary closure. A T-tube was placed in the subhepatic space in the patients of both groups.

RESULTSPostoperative bile leakage was seen in 9 patients of group A and in 5 of group B, respectively (P > 0.05), and no reoperations were necessary. After surgery, the average time and volume of transfusion was 4.9 days and 9.1 liters in group A, versus 7.3 days and 12.8 liters in group B (P < 0.01). The patients in group B had a longer postoperative hospital stay than the those in group A (average 17.6:10.0 days, P < 0.01). T-tube removal resulted in bile peritonitis in 5 patients at day 16, 17, 19, 21 and 22 after surgery in group B, and 3 patients required repeated surgery.

CONCLUSIONSPrimary closure of the common bile duct after choledochotomy is safe, effective, and inexpensive in selected patients with common bile duct calculi, and should be regarded as an alternative procedure.

2600 Anthers from T0 modified cry1 Ac-transgenic rice lines of Minghui 81, an elite restoring line of commercial CMS indica hybrid rice, were cultured on SK3 media. 83 green plantlets were recovered, 43 double haploid (DH) and 40 haploid among them. Results of PCR analyzes indicated that 55 plants of 83 were harbored the cry1Ac gene, and the ratio of cry1Ac-positive against cry1Ac-negative was 2:1 (55/28). 36 putative transgenic DH plants were further confirmed by Southern blot. ELISA detection showed that Cry1Ac level in different transgenic rice plants of the same cry1Ac-DH clone was almost equal and the highest one amount to 0.25% of the total soluble protein. Pest insect-resistant bioassay at field trials demonstrated that some of the homozygous cry1Ac-transgenic rice plants not only showed high-level resistance against striped stem borer (Chilo suppressalis) but also retained elite agronomy characters. These results demonstrated that rice anther culture has a great value in rice molecular breeding.
