Objective To evaluate the clinical therapeutic effects of Vbeam 595 nm pulsed dye laser in114 cases of port wine stains.Methods 114 patients with port wine stains were treated with Vbeam 595 nm pulsed dye laser with 3～10 ms pulse width and 7mm spot size.The energy fluence used varied from 10 to 15 J/cm2.Dynamic cooling device(DCD)was used to protect epiderm,with DCD spray 30～40 ms and DCD delay 10～30 ms.The interval of therapy was 4～8 weeks.The results were graded on basis of cleaning and fading as follows:grade Ⅰ(＞75%),gradeⅡ(50%to 74%),grade Ⅲ(25%to 49%),and grade Ⅳ(＜25%).Results 114 patients completed the therapy.The number of treatments ranged from 1 to 10(mean 5.9).The results evaluated as grades Ⅰ,Ⅱ,Ⅲ and Ⅳ were 74 patients(64.9%),29 patients(25.4%),9 patients(7.9%)and 2 patients(1.8%),respectively.The therapeutic effect was analysed according to number of treatments.the ages of patients,site and color of the lesions.It was found that the therapeutic effect was prominent in patients of younger age,with pink lesions located on the neck and face.No recurrence and scar happened after 6 months to 2 years follow-up.Conclnsions Vbeam 595nm pulsed dye laser is a safe and effective method for the treatent of port wine stains,with less complications.

Retinal vein occlusion (RVO) is a common clinical disease causing vision loss. Risk factors such as diabetes, atherosclerosis are closely associated with RVO. Xuesaitong injection is used extensively in clinical treatment of RVO, however the mechanism is still unclear. In this study, we investigated the protective effect of Xuesaitong injection on RVO rat model. Using a compound-target network of Xuesaitong on anti-RVO constructed by literature mining, we aim to elucidate the multi-compound, multi-target effect of Xuesaitong injection. Fifteen potential targets of Xuesaitong injection associated with inflammation, angiogenesis, apoptosis, and coagulation were identified in this study. VEGF, IL-1beta and IL-6, three important targets in the compound-target network were further experimentally validated. This study provided experimental evidence for Xuesaitong injection being effective in treating RVO and a network view on its anti-RVO mode of action through a multi-compound and multiple-target mechanism.

Objective:To investigate the clinical effect of myocutaneous flap combined with antibiotic-loaded polymethylmethacrylate (PMMA) cement in the treatment of Cierny-Mader type III-IV osteomyelitis.Methods:From April, 2014 to March, 2019, 53 patients with Cierny-Mader type III-IV chronic osteomyelitis were treated with myocutaneous flap combined with antibiotic-loaded PMMA cement. There were 33 males and 20 females, with an average age of (52.2±3.0) (29-78) years old. The area of the wound ranged from 2.0 cm×2.0 cm to 14.0 cm×28.0 cm. All flaps were closed directly. There were 23 patients who were removed the cement at 3 months after surgery, and the other 30 were not. After the surgery, the blood supply of the flap, the effusion of the wound, the complications of the donor area, signs of fresh bone destruction on X-ray and the color, the texture and scar of the flap were observed in the follow-up at the clinic.Results:Forty-nine cases healed in one stage, and 4 had delayed healing. Postoperative vascular crisis occurred in 6 cases and releasesd by prompt surgical exploration. The patients were followed-up for 0.6-3.0 years, with an average of 18 months. All 53 myocutaneous flaps completely survived ultimately. The color of flaps was similar to the recipient areas, and the flaps were smooth and soft and satisfactory in appearance. During the follow-up period, X-ray examination showed no sign of fresh bone destruction. Osteomyelitis was significantly controlled. There was no inflammation reaction such as swelling, pain, ulceration and effusion of the flaps, and there was no recurrence of osteomyelitis. All donor areas healed primarily.Conclusion:Myocutaneous flap combined with antibiotic-loaded PMMA cement has achieved good anti-infection effects in satisfactory results, less postoperative complications and low recurrence rate in the treatment of Cierny-Mader type III-IV osteomyelitis. Application and promotion of such technique would deliver good benefits.

To research the effect of continuous cropping on cotton soil microorganisms and soil microorgan-isms on grow of cotton,we studied the total numbers of aerobic self-nitrogen-fixing bacteria,potassium bacteria,cellulose decomposing bacteria,phosphate solubilizing bacteria,organic-phosphorus-dissolving bacteria distributed in continuous cropping cotton fields of regimental farm 2 and 3 of the first agricultural division through dilution spread plate method.Results showed that the total numbers of five kinds of bacte-ria was highest in blooming and bolling periods,lowest in seeding periods and higher in before sowing pe-riods.The total numbers of five kinds of bacteria was no notable regular changes with continuous cropping year.The numbers of aerobic self-nitrogen-fixing bacteria at different cotton growth stages in regimental farm 2 was higher than in regimental farm 3 and the numbers change of other bacteria was varied in different cotton growth stages in regimental farm 2 and 3.Soil beneficial bacteria were negatively correlated with a variety of soil nutrient ion and free-living nitrogen fixing bacteria were significantly positive correlated with soil total nitrogen.

Lumbar interbody fusion is one of the most commonly used surgical treatment of lumbar disease at present, but the hidden blood loss after surgery is large, accounting for 1/3 or even more than 1/2 of total blood loss. If not monitored and treated for the hidden blood, it can result in anemia and prolong bed time, thereby increasing the chance of infection. This paper summarizes the mechanism, influencing factors, calculation and treatment of hidden blood loss after lumbar fusion, so that the surgeon can have a correct understanding and evaluation of the hidden blood loss for the patients undergoing lumbar intervertebral fusion, and so as to reduce the occurrence of complications. This is very important for helping patients to pass perioperative period smoothly.
