Stribild is a compound preparation composed of elvitegravir, cobicistat, emtricitabine and tenofovir. As for the first-treated AIDs patients or re-treated patients with creatinine clearance≥70ml·min-1 , it has definite clinical effect. Owing to once a day, stribild can enhance the acceptability of the patients, and as for the patients treated with other regimen complicated with diarrhea, pain in stomach and numbness in hands and feet, it also provides a good option. However, its adverse effects on kidney, liver and bone density in the long term use should be paid attention.

OBJECTIVE:To observe clinical efficacy and toxic reaction of bronchial artery infusion(BAI)chemotherapy com-bined with Cinobufacini capsule in the treatment of advanced non-small cell lung cancer(NSCLC). METHODS:A total of 126 cas-es of advanced NSCLC diagnosed in stage Ⅲb-Ⅳ were randomly divided into observation and control group,63 cases in each group. Both of them were treated by BAI with taxotere/cisplatin(TP regimen),once every three weeks for a cycle,a total of 5 cy-cles;observation group was additionally given Cinobufacini capsule 500 mg/time,three times a day,on the basis of BAI chemo-therapy,for 15 weeks. Clinical efficacy,KPS,survival rate and toxic reaction of 2 groups were observed. RESULTS:The total ef-fective rate(82.54%)of observation group was better than that(63.49%)of control group,with statistical significance(P<0.05). KPS score of observation group was significantly better than that of control group,with statistical significance (P<0.05). 1-year survival rate of observation group and control group were 65.08% and 30.15%,2-year survival rate of them were 19.05% and 4.76%,with statistical significance(P<0.05). Adverse reactions of two groups was mainly marrow suppression and gastrointesti-nal reaction,marrow suppression degree and the incidence of nausea and vomiting in observation group was lighter than control group,with statistical significance (P<0.05). CONCLUSIONS:BAI combined with Cinobufacini capsule in the treatment of ad-vanced NSCLC can improve short-term curative effect and long-term survival rate,and can improve the survival quality with little toxic effect.

The efficacy of patients infected with hepatitis C virus complicated with cirrhosis is not promising after treated with present standard therapy. With more and more new drugs against hepatitis C virus, many new regimens for the patients with chronic hepatitis C virus complicated with cirrhosis have come forth. Because the adverse reactions of the first generation HCV protease inhibi-tors telaprevir and boceprevir are severe, they are not recommended to be used in the patients with chronic hepatitis C virus complicated with cirrhosis. The other drugs, such as simeprevir, sofosbuvir and ledipasvir show good efficacy in the patients with chronic hepatitis C virus complicated with cirrhosis, however, the sustained virological response ( SVR) in the patients with chronic hepatitis C virus complicated with cirrhosis is lower than that in the patients with chronic hepatitis C virus without cirrhosis. Therefore, the regimens should be optimized in the future to narrow the gap in SVR.

Objective To evaluate the clinical application of thoracoscope mediastinal tumor resection with the laryngeal mask anesthesia. Methods 40 cases of mediastinal tumors were randomly divided into two groups from 2012 to 2015, 20 cases in each group. Laryngeal mask group performed thoracoscope mediastinal tumor resection with laryngeal mask anesthesia and the Intubation group performed thoracoscope mediastinal tumor resection dou-ble-lume nendo tracheal intubation anesthesia, then compare the overall effect. Results All the patients were suc-cessfully completed with the thoracoscope surgery, no transfer to open chest cases. The preoperative anesthesia time of laryngeal mask group was shorter, blood pressure and pulse range of wave was smaller in the process of anesthesia and surgery, move restlessly was less, postoperative recovery time was shorter, and lower incidence of postoperative pharynx ministry unwell and sore throat, so the laryngeal mask group shows statistically significance comparing with the intubation group (P < 0.05); Operative time, operative field exposure satisfaction, intraoperative blood loss, post-operative extubation time and hospitalization days have no statistical significance (P >0.05). Conclusion The laryn-geal mask airway intravenous anesthesia in thoracoscope mediastinal tumor resection in practical good, in the preop-erative anesthesia and postoperative recovery time and postoperative sore throat was better than that of intubation group, so should be extended in clinical treatment.

Objective To evaluate the feasibility and safety of thoracoscopic lung cancer surgery under non-tracheal intubation anesthesia. Methods Twenty patients with peripheral lung cancer were enrolled in experimental group and control group. Then monitored and recorded Systolic pressure (SBP), diastolic pressure (DBP), mean arterial pressure (MAP), heart rate (HR), electrocardiogram (ECG), heart rate (HR), Oxygen saturation (SpO2), Final moisture CO2 partial pressure (PETCO2), central venous pressure, invasive arterial blood pressure and blood glucose and the related complications like sore throat, hoarse voice, nausea and so onin such time points: before induction (T0), induction of intubation (T1), operation (T2), and sudden removal (T3) of the two groups. Results The laryngeal mask group was given a smaller stimulus to the cardiovascular system during anesthesia.The time of feeding, the exhaust, the time of getting out of bed, the average hospitalization day, the reduction of hospitalization expenses, pharynx, respiratory and cardiovascular complications were shorter and less than intubation group. Conclusion The laryngeal mask ventilation intravenous anesthesia with thoracic vagal nerve block in the thoracoscopic lobectomy is simple, safe, no intubation-related complications and single lung ventilation lung injury, in line with surgery -anesthesia overall minimally invasive development concept, worthy of clinical promotion.

Objective To observe the effect of inferior vena cava filter (IVCF) on prevention of bone cement implantation syndrome (BCIS). Methods Ten sheep were divided into 2 even groups, BCIS and LVCF intervention ones. First IVCF was implanted into the inferior vena cava through cervical vena-right atrium pathway under fluoroscopic monitoring to observe the influence of IVCF on BCIS. Then BCIS was es-tablished in the same sheep by compressing 10 mL of bone cement into a sheep medullary canal after mutilation of the left femur. Arterial blood pressure, heart rate, central venous pressure (CVP) and blood gas were monitored, while an ultrasonic device was utilized to monitor fat embolisms in the right atriums of the sheep. Oil red staining was performed to detect fat embolisms in pulmonary arteries after the sheep were executed. Results In BCIS group, dotted uneven resonances were found in the right atrium and right ventricle when the medullary canal pressure was increased to 120 mm Hg, indicating embolisms in the right chambers. The dotted resonances were increased to ponderous, snowflake-like ones as the medullary canal pressure climbed up. At the same time, blood pressure and Pa02 dropped significantly, the systolic blood pressure dropped to (80±11) mm Hg and PaO<.2> to the minimum 25 minutes after cone cement implantation. The heart rate and CVP increased continuously. The blood gas assay indicated respiratory and metabolic acidosis. The oil red staining showed bulk fat embolus in pulmonary arteries. But in IVCF group, the similar resonances were not observed throughout the surgery and the medullary canal pressure climbed to 400 mm Hg, reaching the maximum of our pressure gage range. The blood pressure, PaO2, heart rate and CVP did not change much compared to those before implantation. The blood gas and pulmonary oil red staining showed few changes either. Conclusion IVCF implantation can prevent the genesis of BCIS.
