Objective To observe the effect of microprismatic needle scalpel(MPNS) on headache induced by compression of greater occipital nerve or lesser occipital nerve.Methods 95 patients with headache induced by compression of occipital nerve were divided into the treatment group (50 cases, treated with MPNS) and control group (45 cases, treated with carbamazepine).Results In the treatment group, 42 cases were cured, 6 cases were effective, 2 cases were ineffective; while, those in the control group were 16 cases, 21 cases and 8 cases respectively. There was a significant difference between two groups ( P<0.01).Conclusion MPNS has an obvious effect on headache induced by compression of occipital nerves.

Aim To study the mechanism of the anti-aging effect of total extract of astragalus(TEA) in mice. Methods MDA content, the activities of Mn-SOD and GSHpx and the reduced to oxidized glutathione (GSH/GSSG) ratio in mitochondria of D-galactose(D-gal) treated mice and 17-month-old mice were measured. Results Treatment with TEA(40 mg?kg-1?d-1 ig) for 10 wk would lower the content of MDA and restore activities of Mn-SOD,GSHpx and GSH/GSSG ratio in mitochondria of D-gal treated mice.Treatment with TEA (40 mg?kg-1 ?d-1 ig) for 3 mon had the same effect on 17-month-old mice.Conclusion TEA has anti-aging effect on D-gal treated mice and 17-month-old mice significantly, probably being related to its anti-oxidative effect.

OBJECTIVETo observe the efficacy, median survival time, time to progression, quality of life and adverse effect of gefitinib (IRESSA) in the treatment for refractory advanced non-small cell lung cancer (NSCLC).

METHODSForty-one patients with stage III b to IV NSCLC who had previously treated with 2-7 cycles of platinum-based chemotherapy were enrolled into the study, 85.4% of the patients had received second line chemotherapy. The regimen was oral intake of gefitinib 250 mg once daily until the disease progression or intolerable toxic reaction occurred. The patients were required to receive tumor assessment before the treatment, one month, two months and every three months after IRESSA administration.

RESULTSAll 41 patients were evaluable for therapeutic effect. Partial response rate (PR), stable disease (SD) and progression of disease (PD) was 43.9% (18/41), 34.1% (14/41) and 22.0% (9/41), respectively. No complete regression was observed. The overall response rate was 43.9% (18/41) with a rate of 42.1% in the male and 45.5% in the female (P > 0.05). The disease control rate (PR + SD) was 78.0% (32/41). Twenty-two of the 41 patients (53.7%, 22/41) were still alive with MST of 10.1 months when the follow-up ended in Nov. 2006. TP and MST of dead patients was 2.7 and 5.0 months, respectively. The rate of symptom improvement was 78% for all patients with MST of 13.3 months for PR patients. The performance status (Karnofsky) was improved (20 +/- 5) after 28-day treatment. III-IV degree toxicity was not observed.

CONCLUSIONIRESSA is effective and safe for the advanced NSCLC patients with poor performance status who previously failed in the second or third line chemotherapy.

Objective To compare the effects of hepatic vein occlusion with tourniquet and Satinsky clamp in reseeting liver tumor involving the second hepatic portal.Methods From Jan 2003 to Jun 2006,180 patients underwent major liver resection with the selective hepatic vascular exclusion (SHVE).According to methods of hepatic vein occlusion,they were divided into two groups:Occlusion with tourniquet(tourniquet group,n=95)and occlusion with Satinsky clamp(Satinsky clamp group,n= 85).In tourniquet group,the hepatic veins were encircled and occluded with tourniquet,and in Satinsky clamp group,the hepatic veins were not encircled and clamped directly with Satinsky clamp.Data regarding the intraoperative and postoperative courses of the patients were analyzed.Results There was no difference between the two groups regarding the operating time,ischemia time,intraoperative blood loss and postoperative complications rate.The dissecting time of hepatic veins was significantly shorter in Satinsky group(6.2?2.4 min vs 18.3?6.2 min).lu the tourniquet group,five hepatic veins(one fight hepatic vein and four common trunk of left-middle hepatic veins)could not be dissected and encircled because of the tumors involving the cava hepatic junction.Another patient's common trunk of left-middle hepatic vein was inadvertently lacerated during the dissection.Hepatic veins in these 6 patients were occluded with Satinsky clamp successfully.Conclusion Occlusion with Satinsky clamping is safer and easier procedure than tourniquets in the resection of liver tumor involving the second porta hepatis.

UL48 plays essential role in replication of MDV genome and interacts with UL36 as well as other MDV tegument proteins.To investigate the interaction between UL48 and UL36 during MDV oncogenisis,antibody against UL48 was prepared and characterized in current study.UL48 gene was amplified from MDV-Ⅰ genome and then subcloned into pTYB1 and pGEX-4T3 vectors for UL48 expression with induction of IPTG in BL21(DE3) E..coli cells.Chitin-sepharose and Glutathion-sepharose were,respectively,used to purify fusion protein intein-UL48 and GST-UL48.Four subcutaneous injections of intein-UL48 fusion protein were done on the lower back and the thigh of rabbit and then other three injections with an interval 10 days.The titer of antibody was measured by the sandwich ELISA with UL48 protein isolated from GST-UL48 after cleavage of thrombin.Western blot was carried out for specificity analysis of antibody against UL48 protein.The results suggested that UL48 antibody was succesfully prepared,and its titer was 1 ∶ 512 000.

OBJECTIVETo investigate the biomechanical differences between the surgery and adjacent segments of intervertebral discs in the lower lumbar spine, which were implanted with Coflex into the segments of L4, and L5S1, respectively.

METHODSThree finite-element models (the model of the intact lower lumbar sacrum,the L4.5 and L5S1 segments implanted by Coflex) were developed, respectively. According to the spinal three-column loading theory, three models were forced by the physiological loads of upright standing, flexion and extension. The stress of the different areas of the disc annulus, the changes of intervertebral dorsal height and the degree of nucleus pulposus pressure were compared and analyzed.

RESULTSCoflex implanted into the L4.5 and L5S1 segments in compression and extension could both decrease the stress of the posterior area of intervertebral disc in the surgery segment, resist the changes of the intervertebral disc dorsal height and reduce the perssure of nucleus pulposus. Furthermore, the stress of the L5S1 segment decreased when Coflex fixed the L4.5 segment in extension. However, when Coflex fixed the L5S1 segment, the stress of L4.5 segment had no significant changes.

CONCLUSIONCoflex fixing the L4,5 and L5S1 segments can effectively decrease the stress of the surgery segmental discs, respectively. Furthermore, Coflex fixing L4,5 segment may play a biomechanical role in reducing the stress of L5S1 segment.

Objective: To learn the prevalence and drug resistance of nontuberculous mycobacteria ( NTM ) in Zhejiang Province, so as to provide evidence for NTM prevention and control. Methods: A total of 2 878 clinical mycobacterium isolates in Zhejiang Province were collected from the drug resistance surveillance in 2008-2009, 2013-2014 and 2018-2019, PNB/TCH growth tests were used to preliminarily identify the NTM in these mycobacterium-positive isolates. 16SrRNA, rpoB, ITS and hsp65 gene sequencing analysis were used to confirm strains initially identified as NTM. Proportional method was applied to detect drug susceptibility of NTM isolates. Results : Finally, 135 strains were confirmed as NTM and the isolation rate was 4.69%. The isolation rates of NTM in 2008-2009, 2013-2014 and 2018-2019 were 1.85%, 4.56% and 7.84%, respectively, with an increasing trend ( P<0.05 ). Thirteen species were identified and the top two species were M. intracellulare ( 82, 60.74% ) and M. kansassi ( 18, 13.33% ). The NTM isolates showed the highest drug resistance rate to isoniazid ( 97.78% ), followed by p-aminosalicylic acid ( 94.87% ) and streptomycin ( 94.81% ). Conclusions The isolation rates of NTM showed an upward trend in the drug resistance surveillance in 2008-2019,2013-2014 and 2018-2019 in Zhejiang Province. M. intracellulare and M. kansassi were the main strains isolated. The NTM isolates showed high resistance against both first and second-line antituberculosis drugs.

OBJECTIVETo study the clinical manifestations and radiological characteristics, diagnostic methods and outcomes of pulmonary mucosa-associated lymphoid tissue-derived(MALT) lymphoma.

METHODSA retrospective review of clinical, radiological and follow-up data of 29 pulmonary MALT lymphoma cases at Shanghai Pulmonary Hospital affiliated to Tong Ji University from January 2002 to June 2010 was performed.

RESULTSAmong these patients, there were 19(65.5%) males and 10 (34.5%) females aged from 27 to 73 (median 53) years old. Common clinical manifestations were cough (51.7%), fever (20.7%), apnea (17.2%), chest pain (17.2%), fatigue (13.8%) and weight loss (13.8%), while 9(31.0%) cases had no symptoms at diagnosis. The characteristics of the chest CT showed that 22 (75.9%) of the cases had patch infiltration or consolidation of the lung, 7(24.1%) of the cases had mass, and 15 (51.7%) unilateral and 14(48.3%) bilateral lesions. Their diagnosis duration varied between 0.5 and 96 months. 18(62.1%) cases were confirmed by surgery (15 open lung and 7 video-assisted thoracic surgery, VAST), 4 (13.8%) by percutaneous lung biopsy, 5 (17.2%) by bronchoscopic biopsy, and 2 (6.9%) by peripheral lymph node biopsy. The treatment methods included surgery, combined chemotherapy, radiotherapy and Chinese herbal medicine. The 1- and 3-year-survival rates were 92.3% and 87.4%, respectively.

CONCLUSIONSPulmonary MALT lymphoma is atypical in clinical manifestations and radiological characteristics, and easy to be misdiagnosed. Local diseases are mainly treated by operation while extensive diseases receive combined chemotherapy. A proper diagnosis is mainly based on pathological biopsy. Patients with MALT lymphoma have a favorable outcome. Poor prognosis may be connected with poor performance status and long diagnosis duration.

OBJECTIVETo evaluate the effect of chronic virus infection on laboratory tests results in patients with osteoarticular tuberculosis.

METHODSA total of 121 patients with osteoarticular tuberculosis, who were hospitalized in Shenzhen Third People's Hospital during June 2008 to June 2012, were recruited for analysis. Clinical laboratory tests results were collected for comparison between patients with or without chronic co-infection with virus.

RESULTSAmong the 121 patients, thirty patients were co-infected with hepatitis B virus (HBV), two were with Human immunodeficiency virus (HIV), and one was co-infected with HBV, HIV and hepatitis C virus (HCV). Compared to patients with osteoarticular tuberculosis without HBV/HCV/HIV infection, patients with chronic HBV/HCV/HIV virus infection had similar positive rate of laboratory tests including tissue smear acid-fast bacilli (AFB) staining, tissue Mycobacterium tuberculosis (Mtb) culture, tissue Mtb DNA detection, serological test of antibodies against Mtb, and Mtb. antigen-specific interferon-gamma release assay. Similar results were also found for erythrocyte sedimentation rate, C-reative protein level and liver function including Alanine aminotransferase and Aspartate Aminotransferase.

CONCLUSIONChronic infection with HBV/HCV in patients with have no obvious effect on clinical laboratory tests related to tuberculosis.
