OBJECTIVETo study the function of radiosurgery on malignant glioma by analyzing prognostic factors affecting malignant gliomas treated with linac radiosurgery.

METHODFifty-eight patients with deep situated malignant gliomas, aged 7 to 70 years, 28 anaplastic astrocytomas and 30 glioblastomas multiforme were analyzed. The median volume of tumor was 10.67 cm3, and median prescription dose for linac radiosurgery was 20 Gy. Results were analyzed with Kaplan-Meier curve and Cox regression.

RESULTIn follow-up 44.8 percent tumors (26 patients) decreased in size. Median tumor local control interval was 10 months, 15 months for anaplastic astrocytomas, and 9 months for glioblastoma multiforme. Tumor local control probability was 37.9 percent for 1 year and 10.3 percent for 2 years. Median survival was 22.5 months for anaplastic astrocytoma, 13 months for glioblastoma multiforme, and 15 months for all patients. The survival probability was 79.3 percent at 1 year and 20.6 percent at 2 years. Isocenter numbers and tumor volume were the prognostic factors for tumor control, but conformity index was the prognostic factor for survival by Cox regression analysis. Considering pathology, only isocenter number and target volume significantly affected tumor control interval. Complications appeared in 44.8 percent patients and the median interval of complication onset was 8 months. Symptomatic cerebral edema was observed in 31.0 percent patients.

CONCLUSIONLinac radiosurgery can effectively improve tumor local control and prolong survival for deep situated malignant gliomas.

OBJECTIVETo evaluate the effects of primary duct closure and T-tube drainage in laparoscopy choledochotomy to treat the common bile duct stones.

METHODSThe enrollment of the patients was in accordance with 6 criteria. 55 patients with cholecystolithiasis and secondary common bile duct stones from January 2000 to February 2003 were treated with laparoscopic choledochotomy. The patients were randomly divided into two groups: primary duct closure group and T-tube drainage group. Their all data were recorded and studied prospectively,and patients were followed up after discharge.

RESULTSThere were 27 patients and 28 patients in primary duct closure group and T-tube drainage group respectively. The operation time and the results of following up between the two groups had no significant difference. Compared with T-tube drainage group, primary duct closure group had less the total quantity of postoperative transfusion and hospital costs, shorter postoperative hospital stay. The incidence of postoperative complications in primary duct closure group was 11.1% (3/27), and all of them were biliary complications. The incidence of postoperative complications in T-tube drainage group was 28.6% (8/28), and seven of them were biliary complications. The incidence of severe complications that needed reoperations was 10.7% (93/28), and all of them were caused by T-tubes. There was no mortality in two groups.

CONCLUSIONSThe primary duct closure in laparoscopic choledochotomy can avoid the deficiency of T-tube drainage, and it is feasible and safe and lower complications in treating the common bile duct stones, so we advocate it in appropriate cases.

OBJECTIVETo explore the factors influencing cardio-cerebro vascular death events among people over 40 years of age in Shandong area, China.

METHODSBaseline survey was carried out in 1991. A total number of 11,008 adults over 40 years old had been studied in Shandong province. Data on cardiocerebro death was collected. The correlation between influencing factors and cardio-cerebro vascular death events was analyzed by Cox regression model.

RESULTSTotally, 434 cardio-cerebro death events occurred among the 11,008 subjects during the 8-year follow-up study. Cardio-cerebro death events were related to systolic blood pressure, diastolic blood pressure, smoking, stroke history and age. Data from Cox regression analysis showed that the relative risk (RR) for cardio-cerebro vascular death events increased by 2.862 [95% confidence interval (CI): 1.976-4.144] times for those people having stroke history. When systolic blood pressure, diastolic blood pressure increased by every 10 mm Hg, the relative risk for cardio-cerebro vascular death events increased by 1.171 (95% CI: 1.033-1.328), 1.214 (95% CI: 1.044-1.413) respectively. it was found that a 1.239 (95% CI: 1.088-1.553) times higher in smokers than non-smokers on relative risk for cardio-cerebro vascular death events. However, the predictive values of the influencing factors for cardio-cerebro vascular death were different among population of different years of age. The relative risk for cardio-cerebro vascular death events increased by 1.366 (95% CI: 1.102-1.678) times for each 10 mm Hg increase of diastolic blood pressure in 40-59 years old population. However, the effect was taken place by systolic blood pressure in 60-74 years old population,with a relative risk of 1.201 (95% CI: 1.017-1.418) for each 10 mm Hg increase. Age seemed the only significant factor for cardio-cerebro vascular death events on population aged more than 75 years old. Conclusion The predictive values of the risk factors were different among age groups. The different risk factors should be taken care according to the difference of age.

OBJECTIVETo detect gene mutations associated with hypertrophic cardiomyopathy (HCM) in Chinese patients and possible correlations between genotype and phenotype.

METHODSTwenty-one unrelated patients with hypertrophic cardiomyopathy were studied. The clinical data including symptoms, physical examination, echocardiography and electrocardiography were collected. The full ecoding exons of cardiac myosin-binding protein C gene (cMYBPC3) were amplified with PCR and the products were sequenced.

RESULTSTwo mutations were identified in probands from two families. One mutation was frame shift mutation Pro1208fs in the exon 32 of the cMYBPC3 gene. Pro1208fs mutation was identified in a 59 years old female patient with familial hypertrophic cardiomyopathy. Symptom onset was late and a favorable clinical course was evidenced in this patient. Another mutation was missence mutation Gly507Arg in the exon 17 of the MYBPC3 gene identified in a 24 years old male patient. Diffuse thickness of left ventricular wall, impaired diastolic function and enlarged left atria were evidenced in echocardiography. No mutation was identified in the 80 control healthy individuals.

CONCLUSIONcMYBPC3 might be the disease-causing genes in Chinese patients with hypertrophic cardiomyopathy.

OBJECTIVETo evaluate and analyze mechanism of Pizhen for the treatment of pain in patients with knee osteoarthritis.

METHODSEighty-five patients (85 knees) were divided into two groups according to random number table method. Among 35 patients in the experimental group, 6 patients were male and 29 patients were female, 1 patient lost follow-up, the average age was (56.65 +/- 4.89) years, and the patients were treated with Pizhen. Among 50 patients in the control group,there were 6 males and 44 females, the average age was (57.54 +/- 4.91) years, and the patients were treated with intra-articular injection with sodium hyaluronate. The VAS score and the data of algometer from the most obvious tenderness around the knee were used to evaluate the clinical effects.

RESULTSThere were significant differences of scores in the experimental group before and after treatment (P<0.01). There were significant differences of scores in the control group before and after treatment (P<0.01). After treatment, there were no statistical differences of VAS score and the data of algometer between experimental and control groups ( P>0.01). There was negative correlation between VAS score and the data of algometer.

CONCLUSIONThe Pizhen is an effective method to treat pain in patients with knee osteoarthritis by relaxing tendon of soft tissue around pain point of knee joint, and relaxing compress and stimulation of nerves.

Objective To explore the management of spontaneous intraspinal hematoma.Methods From January 2011 to July 2018,29 cases with spontaneous intraspinal hematoma were admitted to our department.Date on etiology,clinical presentation,radiological features,treatment strategy and prognosis were analyzed retrospectively.The prognosis was assessed by American Spinal Injury Association impairment scale (ASIA) before and after the treatment.Results Total of 29 cases,only 10 cases (34.5％) revealed specific etiology,including 7 cases of spinal vascular malformation,2 of tumor apoplexy,1 of cavernous hemangioma.After 2 weeks of conservative treatment,3 patients with grade D and 3 patients with grade E were assessed for spinal function.The average interval from onset to surgery was(9.4±7.5) days,the ASIA after two weeks of the operation was as follows:5 patients were assessed at grade A,5 patients at grade C,8 patients at grade D and 4 patients at grade E.28 patients were followed up for (48.7±23.1) months on average,6 patients without surgery were E,22 cases with surgery were as follows:4 cases A,18 cases D/E.Conclusions The etiology of spontaneous intraspinal hematoma is hard to define even after complete preoperative examination and exploratory operation.The preoperative neurologic functions are important predicting factors for the prognosis of spontaneous intraspinal hematoma.For patients who had neurologic function deficit,surgical treatment should be performed urgently to remove the hematoma and release the decompression of spinal cord.The majority of these patients can achieve a positive prognosis after surgery.

OBJECTIVETo study the impact of arsenic trioxide (As2O3) on human colorectal carcinoma LS-174T cells and their activity of telomerase.

METHODSLS-174T cells and xenograft model of nude mice were treated with As2O3. The inhibitory effect of As2O3 on survival of LS-174T cells was determined by MTT assay. Apoptosis was determined by electron microscopy and fluorescence microscopy. Cell cycle was assessed by flow cytometry. Telomerase activity in LS-174T cells was determined by PCR-ELISA kit.

RESULTSWith the increasing concentration of As2O3, the ratio of living cells to dead cells decreased significantly, and the IC50 value was 5.23 micromol/L. Apoptosis curve appeared after 24 h and cells turned to apoptosis in a time-dependent manner. As2O3 inhibited the telomerase activity in cell extraction, obviously in a concentration-dependent and time-dependent manner. Inhibitiory effect of As2O3 on xenograft model of nude mice was observed by tumor volume and weight measurement, showing a significant difference between As2O3 and control groups (P < 0.05).

CONCLUSIONBoth the experiments in vitro and in vivo showed an inhibitory effect of As2O3 on colonrectal cancer S-174T cell growth, probably by induction of apoptosis and inhibition of telomerase activity.

Sjögren's syndrome(SS)is a chronic autoimmune disease that affects exocrine glands, especially salivary and lacrimal glands. The main clinical manifestations are dry mouth and dry eyes, but also multi-organ and multi-system can be involved. Cold agglutinin disease(CAD)is an autoimmune disease characterized by red blood cell agglutination in the blood vessels of extremities caused by cold agglutinin at low temperature, resulting in skin microcirculation disturbance, or hemolytic anemia. Cold agglutinin disease is divided into two categories, primary cold agglutinin disease and secondary cold agglutinin disease. Primary cold agglutinin disease is characterized with cold agglutinin titer of 1 ∶4 000 or more and positive Coomb's test. However, the Coomb's test is not necessarily positive and the cold agglutinin titer is between 1 ∶32 and 1 ∶4 000 in secondary cold agglutinin disease. Here, we reported an elderly patient admitted to hospital due to fever. He was diagnosed with respiratory infection, but he showed incompletely response to the anti-infection treatment. Further laboratory tests showed the patient with positive ANA and anti-SSA antibodies. Additionally, the patient complained that he had dry mouth and dry eyes for 1 year. Schirmer test and salivate gland imaging finally confirmed the diagnosis Sjogren's syndrome. During the hospital stay, the blood clots were found in the anticoagulant tubes. Hemolytic anemia was considered as the patient had anemia with elevated reticulocytes and indirect bilirubin. In addition, further examination showed positive cold agglutination test with a titer of 1 ∶1 024, and cold agglutinin disease was an important type of cold-resistant autoimmune hemolytic anemia. Furthermore, the patient developed cyanosis after ice incubating at the tip of the nose. Hence, the patient was diagnosed as CAD and he was successfully treated with glucocorticoids instead of anti-infection treatments. Hence, the patient was diagnosed with SS combined with secondary CAD. SS combined CAD are rarely reported, and they are both autoimmune diseases. The abnormal function of B lymphocytes and the production of autoantibodies might be the common pathogenesis of them. Cold agglutinin disease can lead to severe hemolytic anemia, even life-threatening. In clinical practice, timely recognizing and dealing with CAD might promote the prognosis of the patient.
