Objective To investigate the relationship between Oxfordshire community stroke project(OCSP) classification and imaging classification in acute cerebral infarction. Methods Two hundred and thirty-six patients with acute cerebral infarction were retrospectively evaluated with OCSP classification and imaging characteristics. Results According to OCSP classification,of all the 236 patients with acute cerebral infarction,28(11.9%) experienced total anterior circulation infarction(TACI),71(30.1%) partial anterior circulation infarction(PACI),94(39.8%) lacunar infarction(LACI),and 43(18.2%) posterior circulation infarction(POCI).The consistency was found in 171 cases(72.5%) between the OCSP classification and imaging classification,with the accuracy of 76%(25/33) for TACI,81%(34/42) for PACI,71%(81/114) for LACI and 66%(31/47) for POCI. Conclusion OCSP classification can predict the location and size of cerebral infarction with a high accuracy,and is well consisted with the imaging findings.

ObjectiveTo investigate the therapeutic effect of Xiaoqinglong decoction for supplementary treatment of patients with ventilator-associated pneumonia (VAP).Methods Thirty-three VAP patients with syndrome of traditional Chinese medicine (TCM) as interior retention of phlegm and exopathic cold admitted to Affiliated Hospital of Tianjin Academy of Traditional Chinese Medicine (TCM) from July 2011 to December 2014 were enrolled, and their historical data were retrospectively analyzed. According to the difference in treatment methods, the patients were divided into TCM treatment Xiaoqinglong decoction group (observation group, 18 cases) and general treatment group (control group, 15 cases). The patients in both groups were given conventional western medicine treatment, including anti-infection, phlegm elimination and cough relieve, protection of gastric mucosa and organ function, nutritional support, prevention of bedsore and thrombosis, etc. Additionally, the patients in TCM treatment group were given Xiaoqinglong decoction (drug composition: herba ephedrae 15 g, ramulus cinnamomi 15 g, herba asari 15 g, rhizoma zingiberis 15 g, chinese peony 15 g, rhizoma pinelliae 15 g, fructus schisandrae 15 g, radix glycyrrhizae preparata 10 g) for nasal feeding, once 150 mL, twice a day, once every 7 days. The changes in body temperature were observed before and 3 days and 7 days after treatment, and peripheral blood was collected for determination of white blood cell count (WBC) and C-reactive protein (CRP) level in the two groups. Comprehensive therapeutic effects of the patients in both groups were recorded.Results There were no significant differences in body temperature, WBC and CRP before treatment between the two groups. After treatment, the above parameters in both groups were significantly lower than those before treatment, and they showed a decrease tendency with time prolongation. The decrease in body temperature and WBC in observation group was more obvious than those of control group, and the comparisons showed statistical significant differences on 7 days after treatment [body temperature (℃): 36.5±0.6 vs. 37.0±0.8, WBC (×109/L):6.7±3.0 vs. 8.9±2.5, bothP < 0.05], but there was no significant difference in CRP between the observation group and control group (mg/L: 3 d was 73.7±20.5 vs. 61.5±18.4; 7 d was 27.2±10.5 vs. 23.5±9.1, bothP > 0.05). The total effective rate on the 7th day after treatment in observation group was higher than that of control group [83.3% (15/18) vs. 80.0% (12/15)], but no statistical significant difference was seen (P > 0.05).Conclusions The Xiaoqinglong decoction can reduce the inflammatory reaction of patients with VAP, and improve their symptoms.

This article studies the thermostability and the crystal structure of a new anticancer drug dasatinib. The thermostability of dasatinib was analyzed using the differential scanning calorimeter (DSC) and thermo gravimetric analyzer (TGA), and the structural characteristics of polymorphism and crystalline transformation was determined using the X-ray powder diffractometry (XRD) with in-situ high temperature accessories. The results showed that dasatinib has at least two different crystal forms. The form-I has one crystalline water and form-II one and half, and in a heating-up processing both of them would change their crystal structures. After losing their crystalline water, both would change into the same crystalline form with no crystalline water. Their melting points were almost the same: form-I was 285.68 degrees C and form-II was 285.50 degrees C. The results of the study method would provide a comprehensive reference for the quality evaluation of dasatinib.

Background and purpose:It has a signiifcant effect for erlotinib on treatment of patients with epidermal growth factor receptor mutation in advanced non-small cell lung cancer (NSCLC). But almost all patients will eventually progress for the resistance of drug. This study was to evaluate the efifcacy and safety of retreatment of erlotinib in patients with advanced NSCLC. Methods:It was a retrospective analysis of the 46 advanced NSCLC patients who previously treated with erlotinib and had clinical beneift. The patients were given erlotinib 150 mg orally once daily after failure to other medications until disease progression or the occurrence of intolerable toxicity. The clinical features, therapeutic effect and survival were analyzed. Results: The objective response rate of retreatment with erlotinib was 28.3%. The disease control rate was 60.9%. The rate of symptom relief was 45.7%. The median progression-free survival was 3.6 months. The median overall survival was 7.3 months. One-year survival rate was 8.7%. The median progression-free survival was signiifcant longer in the patients who stopped taking erlotinib more than 6 months than those less than 6 months (P=0.002). The median overall survival was signiifcant longer in the patients whose ECOG ≤2 than those ECOG >2 (P=0.038). The most common drug-related adverse events were rash and diarrhea. Conclusion:The retreatment of erlotinib could possibly prolong the survival time of patients who previously treated with erlotinib and had clinical beneift.

Objective:To introduce recent progress on diagnosis and treatment of benign symmetric lipomatosis(BSL).Method:Detailed clinical data of 6 patients with BSL were reviewed and analyzed.We present a summary of the clinical symptoms,physical sign,diagnosis and therapeutic methods of BSL. And related literatures were discussed together.Result:All of 6 patients have excessive subcutaneous fat deposit predominantly around neck.One patients had upper extremity localizations. Six patients had the complication of left ventricular diastolic function changes,glucose intolerance or diabetes mellitus, chronic hepatopathy, hyperuricemia and sleep apnea syndrome in one or more. One patients with several symptoms occur simultaneously, another one female patient was accompanied by all symptoms but chronic hepatopathy. Five male patient were alcohol abusers. Tatal neck lipentomy and abstinence from alcohol were performed on 5 patients. One patient refused treatment.During a follow-up of 3 months to 4 years, one patients was relapsed again,and no recurrence was seen in another 4 patients. All pathological results were nonencapsulated fat. Conclusion:BSL is a lipodystrophy caused by diffuse fatty tissue, symmetry deposition in the neck and shoulder subcutaneous fascia space or deep fascial space .The highest incidence favors to middle-aged man who is alcoholist. Chronic alcohol addiction and typical clinical symptoms help to diagnosis BSL. Lipectomy represents a successful procedure in treating BSL.
