Objective To determine the quality of life of patients treated with one of three different types of surgery for breast cancer.Methods This was a cross-sectional study using a questionnaire survey completed by Chinese patients without active disease after at least 2 years of follow-up after breast cancer surgery.Results This study totally included 139 breast cancer patients:44 ( 31.6%) had undergone modified radical mastectomy with reconstruction, 41(29.5%)had a quadrantectomy with axillary lymph node dissection, and 54(38.9%)had a modified radical mastectomy without reconstruction.The EORTC QLQ-C30 and EORTC QLQ-BR23 question-naires were used;their reliability was>0.82.Global health status(94.30 ±12.04, P=0.028)and role functio-ning(85.16 ±17.23, P=0.138)were highest in the quadrantectomy group.Pain score was highest in the modi-fied radical mastectomy with reconstruction group(26.13 ±30.15, P =0.042).The breast symptom score (22.56 ±22.30, P=0.009)and body image perception(85.56 ±19.72, P=0.025)were highest in the conser-vative treatment group.The overall health of patients given modified radical mastectomy without reconstruction was lower(72.61 ±20.89, P=0.014) in women older than 50 years compared with younger women.Conclu-sions The quadrantectomy with axillary lymph node dissection procedure had better acceptance, but the overall health status did not differ between groups.Overall health status is lower in women older than 50 years receiving a modified radical mastectomy without reconstruction.

Radiation-induced lung injury (RILI) is a common complication in thoracic cancer patients through radiotherapy, which can be divided into the early-stage radiation-induced pneumonitis (RP) and late-stage radiation-induced lung fibrosis (RILF). At present, glucocorticoids are mainly adopted in the clinical treatment of RP. However, there has been no effective medical treatment for RILF. RILF patients will eventually die from respiratory failure. The exact mechanism of RILI remains unclear. Current studies have proposed that its possible pathogenesis might consist of genetic heterogeneity, oxidative stress and cell damage. In this review, studies related to the pathogenesis of RILI were summarized.

The hydrogen peroxide low temperature plasma sterilization technology solved the problems of thermo-sensitive materials' disinfection and sterilization based on its development and unique characteristics. This paper introduced the researches of clinical application quality control, and showed the hydrogen peroxide low temperature plasma sterilizers were being widely used in hospitals and highly recognized.

Objective To observe the clinical efficacy of point injection at Xialiao point (BL 34) for levator ani syndrome. Methods A hundred levator ani syndrome patients were randomly allocated to a treatment group and a control group, 50 cases each. The treatment group received point injection at Xialiao point (BL 34) and the control group was intervened by biofeedback therapy. The Visual Analogue Scale (VAS), component scores of the MOS 36-item Short-From Health Survey (SF-36), anal resting and squeeze pressures were recorded in the two groups before and after the treatment. The therapeutic effects and therapy costs were compared between the two groups.Results The VAS, component scores of SF-36, anal resting and squeeze pressures were significantly changed after intervention in the two groups (P<0.05). After treatment, the VAS, a part of the SF-36 score [physiological function (PF), body pain (BP), vitality (VT) and social function (SF) scores], anal resting and squeeze pressures in the treatment group were significantly different from that in the control group (P<0.05). The total efficacy rate was 88.0% in the treatment group versus 80.0% in the control group, and the difference was statistically significant (P<0.05). The therapy costs in the treatment group were (327.31±13.42) RMB and (408.45±21.56) RMB in the control group, and the difference was statistically significant (P<0.01).Conclusions Point injection at Xialiao point (BL 34) is an effective method for levator ani syndrome.

AIM: To describe the prevalence and causes of low vision and blindness in a population within Sichuan province in southwestern China.METHODS: A stratified, multi-phased and cluster probability sampling design was employed to enumerate 125 641 participants from 40 351 households within 38 counties/cities. Participants underwent a comprehensive eye examination, including standardized visual acuity (VA) tests using logarithm of the minimum angle resolution charts. Prevalence was age- and gender-standardized to the 2000 China Census.RESULTS: Population-weighted prevalence of blindness was 0.77% (95% CI: 0.72- 0.82, n=966) and low vision was 1.22% (95% CI: 1.14-1.27, n=1 513). Overall, the prevalence of visual disability was 1.40% in the urban population, and 2.22% in the rural population (P<0.01). Cataract was the leading cause of visual disability (55.7%, n=1 381), and was of similar frequency in both urban and rural populations. Retinal disease was the second leading cause (9.7%, n=236), but was more common in urban than rural participants (34.3% vs 2.7%, P<0.01). Corneal disease accounted for 6.5% (n=161) of cases of visual disability, and was more common in the rural population (7.2% vs 3.9%, P=0.006). CONCLUSION: We estimate that 1.72 million people suffer from visual disability within Sichuan province, of which 525 000 are blind, the focus of blindness prevention should be in rural area.
