Objective To study the distribution and related factors of curative care expenditure (CCE) of injury in Gansu Province in 2017. Methods Based on the "A System of Health Accounts 2011 (SHA 2011)", the curative care expenditure of injury in Gansu Province was calculated and analyzed. The five?stage stratified cluster sampling method was adopted to extract 149 medical and health institutions, 120 township hospitals (including community health service centers), 150 individual clinics and 600 village clinics (including community health service stations). The top?down allocation method was used to calculate the cost of injury treatment in Gansu Province, and the influencing factors were analyzed by multiple linear regression. Results In 2017, the CCE of injury in Gansu province was 3.831 billion yuan, and the expense in general hospitals was 2.708 billion yuan. Among them, the cost of lower limb injury and head injury were 1.090 and 0.847 billion yuan. People aged 40 to 69 years old spent 1.901 billion yuan on injury treatment, and the CCE of injury treatment for men and women were 2.422 and 1.409 billion yuan respectively. The results of multiple linear regression showed that hospitalization expenditure was significantly associated with length of stay, operation, hospital grade, age, payment method and gender (P<0.001). Conclusion The economic burden of injury in Gansu Province is relatively heavy, so it is necessary to focus on preventions for different groups and costly injury sites.

OBJECTIVETo compare the efficacy of decollement, combined tumescent liposuction and curettage, Botox injection in the treatment of osmidrosis.

METHODSFrom September 2006 to April 2009, 350 patients with osmidrosis were treated by decollement method in 180 cases, curettage in 120 cases,and Botox injection in 50 cases. The therapeutic effect and complications were retrospectively analyzed.

RESULTSThe patients were followed up for 3-24 months. The cure rate was 90.6%, 84.8% and 84.2% in decollement, curettage and Botox groups, respectively. The effective rate was 100% in all groups.

CONCLUSIONSAll the three methods are effective for the treatment of osmidrosis. The odor symptom can be improved a lot with decollement method. Considering the complication, downtime and cosmetic results, Botox injection is suitable for patients with minor or median odor, while combined liposuction and curettage is selected for patients with median to severe odor.

OBJECTIVETo determine the relative resistance to HIV-1 infection of CD4 + T lymphocytes in HIV-exposed seronegative individuals (ESNs) in China.

METHODSHIV primary isolates were obtained from peripheral whole blood of HIV-infected persons. CD4 + T lymphocytes of Chinese ESNs were separated from peripheral blood mononuclear cells with magnetic cell sorting (MACS). The purified CD4 + T lymphocytes were cocultured with HIV primary isolates. The p24 level was detected and the culture medium was refreshed every 3 days within 2 weeks.

RESULTSFor M tropic HIV strains, p24 level was significantly lower in ESN group than in control group (P < 0.05); for some M tropic HIV strains, even no p24 replicated in ESN group. However, T tropic virus strains had no significant difference between these two groups (P > 0.05).

CONCLUSIONCD4 + T lymphocytes of Chinese ESNs may possess relative resistance to M tropic HIV strains, which may be one of the main influencing factors that result in ESN.

OBJECTIVETo investigate the correction of secondary breast deformities after removement of injected polyacrylamide hydrophilic gel (PAHG).

METHODSFrom March 2003 to March 2008, 100 patients with bilateral breast augmentation with injected PAHG underwent operation to remove the PAHG. The age of patients ranged from 35 to 50 years. Ultrasound and MRI were performed before operation to show the distribution of PAHG and the muscle infiltration around the PAHG. According to the PAHG distribution, muscle infiltration, skin elasticity, infection and PAHG residue, the patients were treated respectively with breast implants at the same stage or at the second stage, or without implants.

RESULTSThe patients were followed up for 3 months to 3 years. The percentage of satisfactory, median satisfactory and dissatisfactory was 90%, 9%, and 1%. In the median satisfactory group, 3 breasts in 3 cases showed slight capsular contracture (Baker II), 8 implants in 6 cases were palpable on the lower pole of the breasts. The middle-aged patient in dissatisfactory group was not satisfied with the high-projected implants shape which were chosen by herself and placed at the second stage. Then implants were removed. There was no complication of implant hernia, infection, wound disruption, or asymmetry.

CONCLUSIONSThe secondary breast deformities could be corrected by breast augmentation with implants. Both breast appearance and the psychological affection can be improved.
