Marine actinomyces LYG-1 was isolated from marine mud flats in Lianyungang,China.Strain LYG-1 was identified using the methods of morphology,physiological and ehemotaxonomic characterization and 16S rRNA gene sequence analysis.The results showed that strain LYG-1 was a marine variable species of Streptomyces roseosporus.The fermentation broth of strain LYG-1 exhibited conspicuous antitumor activity against HepG2,MCF-7,HCT116 and MDA-MB-231 cell lines,and the IC50 values were defined by MTT method respectively.

Isolated tuberculosis of pancreas is very rare clinical entity. Since 1970, we have treated 9 patients, 3 men and 6 women (average 48.3 years), with isolated tuberculosis of pancreas. 2 patients were diagnosed as pancreatic tuberculosis, 1 patient pancreatic cyst and 6 patients pancreatic carcinoma before operation. They all underwent exploratory laparotomy, and were confirmed to be pancreatic tuberculosis by histopathology. Their common characteristics were that tuberculosis was only localized in pancreas without tuberculosis at extrapancreatic sites and that the treatment of anti-TB drugs had much effect on them. By analysis, it was considered that isolated tuberculosis of pancreas was usually mistaken for pancreatic carcinoma because it localized in pancreas, the contents of masses in pancreas should be noted carefully in order to avoid misdiagnosis and treatment of anti-TB drugs should be taken in time.

Objective · To investigate antiemetic effect of aprepitant for moderately chemotherapy-induced nausea and vomiting in patients with gastrointestinal cancer. Methods · From 2014 July to 2015 August, 130 cases of gastrointestinal cancer patients were collected in Ruijin Hospital affiliated to Shanghai Jiao Tong University School of Medicine, who received moderate emetogenic risk of chemotherapy for at least four courses. One hundred and nine patients were treated with aprepitant, palonosetron and dexamethasone on day 1, and aprepitant and dexamethasone on day 2 and 3. Twenty-one patients only received aprepitant and dexamethasone on day 1 and dexamethasone on day 2 and 3 in the first course of chemotherapy. During subsequent courses of chemotherapy they received aprepitant and treated in the same way as 109 patients. MASCC antiemetic tool (MAT) was used to evaluate the intensity of nausea. The primary endpoint was complete response (CR, no emesis and use of no rescue antiemetics) during the overall study phase (0-120 h after chemotherapy) at the second course. The secondary endpoint was complete protection (CP, CR plus no significant nausea) during the overall, acute (0-24 h), and delayed (24-120 h) phases at the second course. Results · The CR rates were 90.0%, 94.6% and 90.8% of patients in the overall, acute and delayed phases, respectively. The corresponding CP rates were 83.8%, 87.8% and 84.6 %, respectively. The CR rate increased from 42.9% to 57.1% during acute phase and increased from 9.5% to 90.5% during delayed phase for 21 patients after treatment with aprepitant. The main adverse reactions include constipation, anorexia and hiccups. Conclusion · Aprepitant combined with palonosetron and dexamethasone can effectively prevent moderately chemotherapy-induced nausea and vomiting in patients with gastrointestinal cancer. Aprepitant therapy can effectively maintain antiemetic effect in patients with many chemotherapy courses.

Objective To investigate the effect of rehabilitation stroke unit on walking in stroke patients with hemiplegia. Methods 86 patients with walking impairment after stroke were randomly divided into control group (n=43), who accepted conventional treatment, and experimental group (n=43), who were incorporated into the rehabilitation stroke unit. They were assessed with Berg Balance Scale (BBS),10 m Maximum Walking Speed (MWS), Fugl-Meyer Assessment (FMA) and modified Barthel Index (MBI) before and 8 weeks after treatment.Results The scores of BBS, MWS, FMA and MBI improved after treatment in both groups (P<0.01), and improved more in the experimental group than in the control group (P<0.05). Conclusion Rehabilitation stroke unit is effective on walking ability in stroke patients with hemiplegia.

OBJECTIVETo study the protective effects of Shenqi Fuzheng Injection (SFI) on cerebral ischemia/reperfusion injured aged rats.

METHODSAged SD male rats, weighing 200-300 g, were randomly divided into 4 groups: the model group, the sham-operative group, the nimodipine positive control group (abbreviated as nimodipine group) and the SFI group. Focal cerebral ischemia/reperfusion injured rat model was established by modified Longa method. SFI was administered by intravenous dripping 1 week before ischemia. Nervous function disorder, brain infarction area, serum lactate dehydrogenase (LDH) and creatine kinase (CK) levels, brain contents of Ca2+ , water, MDA and SOD levels were observed 3 hrs after ischemia and 3 hrs after reperfusion.

RESULTSperimental results showed that SFI could obviously improve the deficit of nerve function, decrease water content of brain, reduce the infarction area of brain, and inhibit Ca2 + aggregation. LDH and CK levels in serum and MDA in brain were obviously lower than those in the model group and SOD activity in cerebral tissue was obviously higher than that in the model group.

CONCLUSIONSFI had protective effect on cerebral ischemia/reperfusion injured aged rats, whose mechanism might be related to the inhibition of lipid peroxidation and Ca2+ aggregation.

Objective: To compare clinical efficacy and safety of microwave therapy versus suction-curettage through small incisions in the treatment of axillary osmidrosis. Methods: Totally, 60 patients with axillary osmidrosis were enrolled from Department of Dermatology, Xijing Hospital, Fourth Military Medical University from January 2017 to February 2018. Every patient received miraDry microwave therapy on the left axillary (microwave therapy group) and suction-curettage through small incisions on the right axillary (suction-curettage group) , and operation duration was recorded. After follow-up of half a year, clinical efficacy and complications were compared between the two groups. Results: After 6-month follow-up, no significant differences were observed in the response rate or recurrence rate between the microwave therapy group (93.33%[56/60], 6.67%[4/60] respectively) and suction-curettage group (96.67% [58/60], 3.33% [2/60] respectively; both P > 0.05) . However, the incidence rate of postoperative complications was significantly lower in the microwave therapy group (0) than in the suction-curettage group (6.67% [4/60], χ² = 4.138, P = 0.042) . Conclusion Compared with suction-curettage through small incisions, microwave therapy has advantages of being non-invasive and less postoperative complications.

OBJECTIVETo study the safety measures during perioperative period in patients with obstructive sleep apnea hypopnea syndrome (OSAHS), to minimize uvulopalatopharyngoplasty (UPPP) major complications.

METHODSThe complications and other relative information of 1446 OSAHS patients treated with UPPP were analyzed. Complications of 1004 OSAHS patients adopted standardized management measures after 2004 and 442 OSAHS patients who performed UPPP before 2003 were compared.

RESULTSAmong the 1446 cases of OSAHS surgery, there were 49 cases (3.39%) of difficult intubation; 8 cases (0.55%) intraoperative mild arrhythmia; 13 cases (0.90%) of surgery dangerous situations after extubation; 19 cases (1.31%) of intraoperative primary hemorrhage; 11 cases (0.76%) of mild arrhythmia during the postoperative observation period; 21 cases (1.45%) of uncontrolled hypertension immediately after surgery; 32 cases of secondary hemorrhage a week after surgery. All complications were cured and no death occurred. Compared with those operations before 2003, complications were significantly reduced with enforcement of standardized management of perioperative measures since 2004. The data had significant difference by chi(2) test (P < 0.05).

CONCLUSIONSThere are five key points during the perioperative period of OSAHS surgery: preoperative examination, intubation, surgery, postoperative extubation, and postoperative care. Risk factors and complications could be prevented effectively in the above five important processes.
