Diagnosis and treatment strategy of penoscrotal avulsion injury based on AAST penoscrotal injury grade / 现代泌尿外科杂志

【Objective】 To explore the emergency treatment of penoscrotal avulsion injury based on the American Association for Surgery and Trauma (AAST) penoscrotal injury grade. 【Methods】 Data of 30 patients with penoscrotal avulsion injury treated in our hospital with in-situ suture, skin grafting or skin flap during Oct.2003 and Dec.2017 were reviewed. 【Results】 Among the 30 patients, 29 received emergency surgery, including in-situ suturein 15 grade Ⅰ-Ⅲ cases, skin graft in 8 grade Ⅳ-Ⅴ cases, and skin flap in 6 cases;1 case received delayed operation due to wound infection on admission. In the perioperative period,25 cases had more than 90% wound healing, 3 cases had 70% wound healing after wound dressing change, and 2 cases had complete necrosis. Second-stage skin graft yielded satisfactory penoscrotal appearance. 【Conclusion】 According to the specific conditions of patients, reasonable surgical methods can be selected. For grade Ⅰ-Ⅲ patients, in-situ suture can be used, while for grade Ⅳ-Ⅴ patients, wound condition, age, fertility and other factors should be taken into consideration so as to preserve the function of testis to the maximum extent.

High-speed and large-responsivity synchronous-traveling carrier photodetector.

A synchronous-traveling carrier photodetector (STC-PD) with a thick absorption region and large diameter is presented and investigated for 100 Gbps PAM4 applications. In the STC structure, a suitable electric field is introduced to synchronize the traveling of electrons and holes, which achieves high bandwidth while maintaining large responsivity. The characteristics of STC-PD, including electric field distribution, energy band diagram, responsivity, junction capacitance, and frequency response, have been studied carefully.

Influence of the incident optical field distribution on a high-speed PIN photodetector and horizontal optimization.

We demonstrate a new, to the best of our knowledge, dimensional "horizontal optimization" scheme, which can improve the high-speed characteristics of a PIN photodetector by designing the incident optical field distribution. First, coaxially incident faculae with the same peak and same power are studied and simulated, revealing that the bandwidth of the photodetector illuminated by uniform light is higher than that of the device illuminated by nonuniform light. Next, an annular optical field is designed incident to the photodetector, and the bandwidth is further improved. For a PIN photodetector, by carefully optimizing the incident optical field distribution, the photodetector bandwidth under an annular optical field can be increased significantly compared with that under conventional coaxial illumination.

Meta Analysis of Dual Antiplatelet Therapy≤6 Months and Dual Antiplatelet Therapy≥12 Months in Patients After Drug-eluting Stent Implantation / 中国循环杂志

Objective: To systematically review the safety and efifciency for dual antiplatelet therapy (DAPT) ≤ 6 months and DAPT ≥ 12 months in patients after drug eluting stent (DES) implantation. Methods: We collected the data for randomized clinical trials for DAPT ≤ 6 months and DAPT ≥ 12 months in patients after DES implantation up to 2015-01 by searching the literatures of PubMed, EMBASE, Cochrane Library, Scopus and Chinese literature database, and meanwhile collected the relevant reporting cases from both domestic and international cardiovascular conferences for this study. There were 2 investigators independently conducted the literature screening, data extraction and quality evaluation, Meta analysis was performed with STATA 12.0 software. Results: A total of 15,378 patients from 7 eligible studies were enrolled and the patients were divided into 2 groups: DAPT ≤ 6 months group,n=7672 and DAPT ≥ 12 months group,n=7706. Meta analysis indicated that DAPT ≤ 6 months could effectively reduce the major bleeding (OR=0.58, 95% CI 0.37-0.91,P=0.017). While the other incidences between 2 groups were similar as all cause death (OR=0.90, 95% CI 0.73-1.11,P=0.314), cardiac death (OR=0.93, 95% CI 0.70-1.24,P=0.617), myocardial infarction (OR=1.13, 95% CI 0.91-1.41,P=0.275), in stent thrombosis (OR=1.21, 95% CI 0.79-1.85,P=0.382) and cerebrovascular accidents (OR=1.00, 95% CI 0.66-1.51,P=1.000). Conclusion: The incidence rates of cardiovascular and cerebrovascular events are similar in patients with DAPT ≤ 6 months and DAPT ≥ 12 months after DES implantation. DAPT ≤ 6 month had the lower risk of bleeding, which is rather suitable for the patients received new generation of DES, with higher risk of bleeding, lower risk of thrombosis and with poor compliance to medication; however, the large and randomized clinical trials are needed to make ifnal conclusion.

Effect of Fluor protector on preventing enamel demineralization / 中国组织工程研究

BACKGROUND: The preventative capabilities of enamel demineralization, rising from the fixed orthodontic treatment, have drawn tremendous attention in recent years. Despite a variety of investigations carried out by both domestic and foreign scholars, whereas, the results of ways to reduce the incidence of demineralization are never fully satisfactory or unified. OBJECTIVE: To evaluate the inhibitory effect of Fluor protector on enamel demineralization based on clinical practices during fixed orthodontic treatment.DESIGN, TIME AND SETTING: Contrast observation was performed in the Department of Stomatology, Qingdao Second Sanatorium, Jinan Military Area Command of Chinese PLA from January 2006 to January 2009. PARTICIPANTS: A total of 132 participants (856 teeth, aged 7-18 years, average age 10.5 years, 76 females and 56 males), who had wall-developed hardened dental tissues, no tetracycline pigmentation teeth, no dental fiuorosis, or anything that constricted in their teeth, were involved in the study. And all subjects were volunteers who had signed the informed consent form and agreed to receive dental treatment and periodic review.METHODS: All the teeth were randomly divided into two groups: experimental and control groups. Teeth for the experimental group were bonded with the supporting brackets with the Fluor protectors, whereas teeth for the control group did basically the same only without the Fluor protectors. After the fixed orthodontic treatment, the supporting devices were removed, all the teeth were fully washed, and then the conditions of the tooth surfaces were observed and documented in both experimental and control groups.MAIN OUTCOME MEASURES: The detection rate of orthodontic enamel demineralization in the two groups alter the fixed orthodontic treatment.RESULTS: After evaluation of the results of both groups, the incidence rate of enamel demineralization in the experimental group (5.51%) was obviously lower than control group (15.1%).CONCLUSION: Fluor protector has a significantly positive effect on preventing enamel demineralizaUon dudng fixed orthodontic treatment.
