Objective:To summarize the development of the HIV/AIDS designated hospital system, analyze the main issues and explore solutions for this system. Methods:184 leaders/experts of three levels of healthcare facilities ( provinces, cities and counties) from 30 provinces engaged in AIDS prevention and control for over five years, and 2,432 people living with HIV/AIDS(PLWHA) from seven provinces were investigated through two different question-naires. Results:According to the staff responses, the issues of surgery and hospitalization are difficult and outstand-ing for PLWHA due to the current designated hospital system with scores of 6. 49 in severity. Of the ten largest prob-lems, ranked third is the need for improved AIDS prevention and control. 2 367 (97. 3%) PLWHAs had an aware-ness of the designated hospitals, 1,376 received treatment in the designated hospitals, and 85. 5% believed that the illness was effectively treated, while 9. 0% thought that the medical technology of the designated hospital was limited;18 . 7% of hospitalized HIV/AIDS patients or those who received surgery experienced prevarication by the non-des-ignated hospitals. Policy analysis shows that China’s designated hospital system for PLWHA has developed gradually with the characteristics of periodic and temporary changes. Conclusion:The designated hospital system for PLWHA in China has played an important role, but there are still several problems. The government should improve the existing system by strengthening the comprehensive medical service capacity of designated hospitals, improving the mechanism of consultation and referrals, coordinating the non-designated hospitals to provide technical support, reducing dis-crimination and fear from medical staff against HIV/AIDS, decreasing the risk of occupational exposure, and enhan-cing the communication among hospitals, CDCs and patients.

Objective:To summarize the main issues, analyze the causes and offer a strategy for AIDS preven-tion and control for all types of healthcare facilities in the health care system. Methods:184 leaders and experts of tertiary-level healthcare facilities ( provinces, cities and counties) from 30 provinces who had been engaged in AIDS prevention and control for more than five years were studied through a questionnaire including the issues and causes in AIDS prevention and control. Results: According to the results of the respondents and experts’ demonstration, the main issues were identified, including a lack of human resources in the system of disease control facilities, a lack of relevant agencies involved in AIDS response, the difficulty for AIDS patients to receive surgery and follow-up, poor detection of HIV, shortcomings in medical insurance, and so on. Conclusion: Based on the analysis of issues and causes, the paper offers strategic solutions: Clearly define the responsibilities of various health institutions in AIDS prevention and control;promote the participation of primary health institutions in AIDS prevention and control; im-prove the medical service system for AIDS patients;improve AIDS medical security policies;reform the management system of antiretroviral therapy drugs;and strengthen technical support from disease control facilities.

Objective To explore the effect of amisulpride and risperidone in the treatment of patients with first-episode schizophrenia and its influence on social function.Methods 70 patients of schizophrenia conformed to the International classification of diseases tenth edition(ICD-10) were randomly divided into amisulpride group(observation group,35 cases) and risperidone group(control group,35 cases) by using the random number table method.The Positive and Negative Scale(PANSS) was used to evaluate the efficacy,the Scale of Social Function in Psychosis Inpatients(SSPI) was used to evaluate social function before and after 8 weeks of treatment.Results After 8 weeks treatment,the negative symptom factor score of the PANSS in the observation group was (15.04±3.55)points,which was improved significantly compared with (17.82±3.87)points in the control group,the difference was statistically significant(t=3.132,P<0.05).The scores of the field in movement and interaction,social activities and skills factor score and the total score of SSPI in the observation group were (15.49±3.54)points,(14.53±4.25)points,(39.25±8.27)points,respectively,which in the control group were (12.78±3.29)points,(10.01±3.78)points,(33.72±7.83)points,respectively,the differences between the two groups were statistically significant (t=3.317,4.701,2.873,all P<0.05).Conclusion Amisulpride is effective in improving the negative symptoms,social function in patients with schizophrenia,and the effect is better than risperidone.

Objective To investigate the indications, techniques and results of laparoscopic hepatectomy. Methods The clinical data and follow-up results of 463 patients who received laparoscopic hepatectomy at our institute were retrospectively analyzed. Results From March 1, 2007 to March 31, 2011, 463 cases of laparoscopic hepatectomy were successfully carried out. Of the 463 patients,165 were with primary liver cancer, 29 with metastatic liver cancer, 143 with hepatic hemangioma, 81with hepatolithiasis and 45 with other benign liver diseases (including hepatic angiomyolipoma, hepatocellular adenoma, focal nodular hyperplasia and chronic liver abscess). The surgical approaches included laparoscopic left lateral lobectomy (93 cases), left hepatectomy (71 cases), extended left hepatectomy (4 cases), right hepatectomy (29 cases), right posterior lobectomy (24 cases), hepatectomy of segment Ⅵ (56 cases), extended right hepatectomy (2 cases), central hepatectomy (8 cases) and hepatectomy of segments Ⅶ/Ⅷ, Ⅳa, caudate lobe and the junction of segment Ⅵ and Ⅶ (41 case).Nonanntomic and wedge resection were performed on 121 patients, and combined resection on 14 patients. The mean operation time, blood loss, length of hospital stay and incidence of postoperative complications were (244.71 ± 105. 07) minutes, (460. 26±425.81) ml, (15.51 ±4.36) days and 9.29%, respectively. And no operative death occurred. In the 194 cases with malignant liver lesions,185 cases were followed up for 2 to 50 months. The 1 year and 3 year overall and disease free survival rate were 90. 8% and 87.9% , 84.2% and 73. 7% respectively. Conclusions As a means of minimally invasive surgical approach, laparoscopic hepatectomy can be selectively adopted for the treatment of all kinds of liver diseases which located at different parts of the liver, with the advantages of smaller trauma, quick recovery and cosmetic benefits. The short-term results of laparoscopic hepatectomy is superior to and its long-term results is equal to that of open surgery. Benign liver diseases, small hepatocellular carcinoma and metastatic liver cancer are the good indications for laparoscopic hepatectomy.

OBJECTIVETo study the course of branches of the superficial temporal artery (BSTA) and the accompanying pattern of their veins in order to provide anatomic basis for flap design.

METHODSHead and facial part of ten adult corpses (19 sides) were dissected and photographed. The coordinate system was set up with external auditory foramen as the point of origin, aided by the graph analysis software Digimizer. The course of the frontal branch and parietal branch of the superficial temporal artery (STA), and the accompanying pattern between the BSTA and the veins were measured and analyzed. The STA and its branches were located by Ultrasonic Doppler, and the corresponding branches of the superficial temporal vein (BSTV) were disclosed by bowing patient's head with breath holding or cerclaging the basement of the patient's skull. And then 10 sides of transposition (fascia) flaps with axis at the angular bisector between BSTA and BSTV were devised to repair wounds of 9 patients that hospitalized from February 2008 to December 2009. Data were processed with test of variance homogeneity.

RESULTSFrontal BSTV absence was found in 6 head sides, and the maximum distance between artery and vein was (2.1 ± 1.2) cm. Parietal BSTV absence was found in 3 head sides, and the maximum distance was (1.4 ± 0.7) cm. The distance between frontal BSTA and BSTV was larger than that between parietal BSTA and BSTV, and the dispersion degree of the former was higher than that of the latter (F = 0.0404, P = 0.0475). All the (fascia) flaps survived without congestion or necrosis.

CONCLUSIONSWhen branch of the superficial temporal vessel was selected as the axial vessel of flap, the flap design shall depend on the accompanying pattern of BSTV to avoid the flap necrosis due to poor venous return after surgery. The superficial temporal vein and its branches can be well disclosed by bowing head or cerclaging skull. The approach is simple, useful, safe, and reliable.

OBJECTIVETo summarize methods for repair of claw hand deformity after burn.

METHODSNinety-seven patients with 136 claw hands after burn hospitalized from May 1992 to May 2007 were repaired with skin grafting (104 hands) and transposition of skin flap (32 hands), among which 21 hands were minor-grade, 92 hands moderate, 23 hands severe. The metacarpophalangeal joint was repaired after scar release in dorsum of hand with manual extraction reduction, release of collateral ligament and joint capsula, separation of adhesion in joint, tendon lengthening for obvious contracture. Restitution of finger flexion deformity, lysis of adhesion and grafting among first web and finger webs, repair of central slip extensor tendon or phalangeal arthrodesis were performed according to the abnormal condition after lysis of dorsal scar of hand. The metacarpophalangeal joint from 31 patients were not repaired with above methods for severe finger flexion deformity, their palmar scar were loosened and transplanted firstly, then scar in dorsum of hand were loosened, metacarpophalangeal joint were repaired, flap or skin were transferred or transplanted. General rehabilitation were performed routinely after operation.

RESULTSThe ending of flaps (4 hands) due to the scar were necrosis after transposition and healed through dressing change, other skins or flaps all survived. Most articular deformities were corrected completely or basically. Functions including palmar opposition, grasp were also recovered with satisfactory results.

CONCLUSIONSkin transplantation and transferring of skin flap with overall planning and individual isatin are the key points for repair of claw hand after burn.

OBJECTIVE: To identify the pathological character of denatured dermis,and its turnover after autologous skin transplant. METHODS: Deep partial thickness burn wounds whose diameter was 2.5 cm were produced on the back of Sprague-Dawley (SD) rats. After simple debriding,xenogenic skin was transplanted. Superficial tangential excision was performed on the burn wounds on 48 hours postburn with the preservation of denatured dermis. Split thickness autologous skin was grafted on the wounds immediately. Tissue samples of whole layer of the skin were harvested from the grafted sites at different time points after the skin grafting. Pathological observation on the denatured skin and the transplanted skin was carried out with HE and Massonos trichrome blue. RESULTS: The superficial cells of the denatured dermis necrotized largely with few cells alive,collagen denatured,and many inflammatory cells infiltrating. Necrosis tissue and inflammatory cells could be found in the denatured skin in the early period after the skin transplant. There were infiltrated inflammatory cells in the transplanted skin 3 days after the skin transplant. On the 10th day,the necrotized tissue diminished markedly,and red cells were found in its upper stratum. On the 21st day, the morphology and structure of the transplanted skin were similar to those of the normal skin. CONCLUSION The retained denatured dermis has little effect on the survival of the transplanted skin. The necrosis components can be absorbed and replaced by the tissue alive after the autologous skin is transplanted.

OBJECTIVETo explore a new method for the repair of the scar in the midface.

METHODSParallel juxtaposed expansion of the skin and soft-tissue of jaw, face, neck and posterior aspect of auricle was performed to repair the scar in the midface of 15 patients. The operation consisted of two steps. In the first step, two expanders were placed subcutaneously under the subskin of jaw, face, neck and posterior aspect of the auricle, respectively, and they were expanded timely to create adequate superfluous skin and soft tissue. In the second step, the expanded skin flap was rotated and advanced to repair the the scar in the midface.

RESULTSParallel juxtaposed expansion was performed to repair the scar in the midface of 15 patients. The incision was comparatively concealed, the colour and elasticity of the skin transplant, and the facial contours were satisfactory.

CONCLUSIONParallel juxtaposed expansion of the skin soft-tissue of jaw, face, neck and posterior auricular is beneficial for the repair of the scar in the midface.

OBJECTIVETo study the effects of antisense p38α mitogen-activated protein kinase (hereinafter referred to as p38α) on myocardial cells exposed to hypoxia and burn serum.

METHODSThirty adult SD rats were inflicted with 40% TBSA full-thickness burn on the back to obtain burn serum. The myocardial cells were isolated from 80 neonatal SD rats and cultured, then they were divided into 4 groups according to the random number table: normal control group (N, ordinary culture without any treatment), hypoxia+burn serum group (HB, exposed to hypoxia after being treated with 10% burn rat serum), hypoxia+burn serum+infection group (HBI, exposed to hypoxia and 10% burn rat serum after being infected with antisense p38α gene-carrying adenovirus), hypoxia+burn serum+empty vector infection group (exposed to hypoxia and 10% burn rat serum after being infected with adenovirus empty vector). At post hypoxia hour (PHH) 1, 3, 6, and 12, mRNA and protein expression levels of p38α in the latter 3 groups were determined by RT-PCR and Western blotting, cell viability was determined by methylthianolyldiphenyl-tetrazolium bromide assay, and lactate dehydrogenase (LDH) activity was assayed at the same time point. At PHH 1, 6, and 12, apoptosis rate of myocardial cells was assessed by annexin V staining method. The indexes of group N were determined with the methods mentioned-above. Three wells were set at each time point in each group. Data were processed with one-way analysis of variance and LSD- t test.

RESULTS(1) At PHH 1, 3, and 6, the p38α mRNA level was higher in group HB than in group N and group HBI (with t values from 2.725 to 4.375, P values all below 0.05). (2) At PHH 1, 3, and 6, the p38α protein level was higher in group HB than those in group N and group HBI (with t values from 5.351 to 7.981, P values all below 0.01). (3) At PHH 3, 6, and 12, the cell viability in group HB (0.115 ± 0.007, 0.104 ± 0.006, 0.094 ± 0.005) was lower than that in group N (0.141 ± 0.014) and group HBI (0.136 ± 0.009, 0.124 ± 0.010, 0.112 ± 0.007, with t values from 2.357 to 6.812, P values all below 0.05). (4) The LDH activity was up-regulated in group HB as compared with that in group N and group HBI at each time point (with t values from 22.753 to 201.273, P values all below 0.01). (5) At PHH 1, 6, and 12, the apoptosis rate of myocardial cells in group HB [(5.4 ± 0.7)%, (8.7 ± 1.1)%, (13.6 ± 1.7)%] was higher than that of group N [(3.1 ± 0.3)%] and group HBI [(4.3 ± 0.5)%, (5.1 ± 0.7)%, (7.2 ± 0.9)%, with t values from 2.345 to 9.700, P < 0.05 or P < 0.01].

CONCLUSIONSAntisense p38α can protect the myocardial cells from the injury of hypoxia and burn serum.
