Objective: To probe into TCM pattern of primary hyperlipemia and its relationship with gender, age, BMI, laboratory indices such as TC,TG, LDL-C, HDL-C, ApoAI, ApoB of the 120 patients with primary hyperlipemia. Methods: Logistic regression analysis wan used to analyze the associativity of TCM syndrome and objective indexes of primary hyperlipemia. Results: Logistic regression analysis showed that TCM syndromes of primary hyperlipemia had some relation with laboratory indices. Conclusion: TCM syndromes of primary hyperlipemia had some relation with laboratory indices. The lipemia laboratory indices can be one of the objective basis of TCM diagnosis. The main syndromes were stagnation of phlegm-turbid and syndrome of yang deficiency of both of spleen and kidney, the main pathogenesis were deficiency of spleen and kidney, intermingled phlegm and blood stasis. The main treatment methods were invigorating spleen and tonifying kidney, supplementing qi and nourishing heart, promoting blood flow and dissipating phlegm.

Objective To study TCM pattem rules of primary hyperlipemia and its relation with sex,age,body mass index(BMI).Methods A total of 1 20 patients with primary hyperlipemia were divided into 5 groups by TCM syndrome differentiation:56 patients in a group of the turbid-phlegm stagnation syndrome,35 patients in a group of yang deficiency of spleen and kidney syndrome,13 patients in a group of yin deficiency of liver and kidney,7 patients in a group of hyperactivity of yang due to yin deficiency group,and 9 patients in a group of qi stagnation and blood stasis syndrome.Statistic analysis was made on factors that may affect these syndromes,and the correlations were discussed.Results Different age showed a closer relation to the onset of primary hyperlipemia than other factors(P＜0.01):sex,clinical classification,and accompanied diseases had no relation with the five-type syndromes(P＜0.01).Conclusion TCM syndromes had a certain relation with the age of patients with primary hyperlipemia.

Objective To study the association between metabolic syndrome (MS) and prognosis of endometrioid carcinoma.Methods A total of 256 patients with endometrioid carcinoma at,Zhejiang Cancer Hospital between January,2001 and December,2008 were chosen.The deadline for follow up was December 2008.The general conditions(including age and body mass index),whether coupled with MS and it's risk factors(including waist circumference,fasting plasma glucose,triglycerides,high-densitylipoprotein,systolic and diastolic blood pressure) were analyzed.The outcome of 256 patients whether coupled with MS were analyzed using Kaplan-Meier curve.Relative risks were estimated using Cox proportional hazards regression model.Results A total of 256 cases were followed-up successfully.Sixtyfour (33.0％) cases coupled with MS among the 194 patients survived,while thirty-two (51.6％)coupled with MS from 62 cases died,there was significant difference between them (x2=6.953,P=0.008).The total fiveyear survival rate was 75.8％,the survival time was (78.0±3.4) months.The rate and the survival time of patients coupled with MS [66.7％,(67.0±2.4) months] were significatly lower than those coupled with no MS [81.3％,(85.0±4.0) months;P＜0.05].The Cox proportional hazards regression results showed that coupled with MS,body mass index ≥25 kg/m2,waist circumference＞80 cm,abnormol systolic and diastolic blood pressure,abnormal fasting plasma glucose and more than two components of definitions of MS were related to bad prognosis of endometrioid carcinoma(P＜0.05).Conclusion Metabolic syndrome may be lead to a bad prognosis of endometrioid carcinoma.

Objective To compare the tracing effects of radionuclide and barium sulfate on lactulose hydrogen breath test (LHBT), and to explore the value of LHBT combined with radionuclide imaging in the diagnosis of small intestinal bacterial overgrowth (SIBO) in patients with irritable bowel syndrome (IBS).Methods From November 2010 to November 2012, 89 patients (47 males, 42 females;mean age (45.7±12.9) years) with IBS and 13 healthy volunteers (9 males, 4 females;mean age (43.3±8.6) years) were enrolled in this prospective study.All the subjects underwent LHBT combined with radionuclide imaging.Recording the time when the increment of H2 value >0.005‰ and the OCTT of the radionuclide.Four healthy volunteers also underwent LHBT combined with barium sulfate 1 week after radionuclide imaging.The location of barium sulfate was recorded when H2 value increment >0.020‰.Patients with SIBO received rifaximin treatment, and the effect was observed.χ2 test, Pearson correlation analysis and Wilcoxon rank sum test were used to analyze the data.Results (1)In LHBT combined with barium sulfate test, barium sulfate was found still stagnating in small intestine by abdominal X-ray when H2 value increment >0.020‰ in 4 healthy volunteers, and barium sulfate didn′t reach the colon in delayed imaging in 1 patient.(2) The rates of SIBO detected by LHBT in IBS patients and healthy volunteers were significantly different (43.8%(39/89) vs 5/13;χ2=0.133, P=0.716), and those detected by LHBT combined with radionuclide imaging were also significantly different (39.3%(35/89) vs 1/13;χ2=4.970, P=0.026).(3)The time of H2 value increased >0.005‰ correlated well with OCTT in 13 healthy volunteers ((73±31) and (50±19) min;r=0.871, P<0.001) and 54 IBS patients without SIBO ((83±34) and (66±28) min;r=0.735, P<0.001), but there was no correlation in 35 IBS patients with SIBO ((36±30) and (75±30) min;r=0.304, P=0.076).(4)A total of 34 SIBO-positive patients received a rifaximin treatment, with a significant improvement in the frequency of abdominal pain and abdominal distension after the treatment according to Rome Ⅲ diagnostic criteria: 5(4, 6) vs 4(3, 5), 4(1, 6) vs 0(0, 4)(z values:-4.842 and-5.388, both P<0.001).Conclusion LHBT alone is not a valid test for SIBO, and LHBT combined with radionuclide imaging is a good candidate for SIBO diagnosis.

Objective To investigate the changes of reactive oxygen species(ROS) level and mitochondria fission-fusion-balance in cortical neurons of rats with chronic fluorosis and reveal the correlation between these two factors. Methods One hundred and twenty rats were randomly divided into 3 groups(control group, low-dose fluorosis group, high-dose fluorosis group) and 40 rats were in each group according to body weight and the experiments were carried out for 3 months or 6 months. The rats were fed with different concentrations of fluoride (NaF) to establish fluorosis models. Controls were fed with tap water( < 0.5 mg/L), experimental animals in low- or high-dose group were fed with water containing NaF 10.0,50.0 mg/L, respectively. The level of ROS and the morphology in mitochondria fission-fusion balance in neurons of the cortex of rat brains prepared with cortical frozen sections were detected with ROS fluorescent probe and MitoTracker RED probe, respectively. Results Significant differences of the level of ROS and the numbers of abnormal mitochondria in morphology in the cortical neurons were found between 3 groups at the experiment period of 3 month and 6 month(F= 3.07,3.06,3.05,3.07, all P < 0.05). As compared with control group(10.43 ± 5.98,4.12 ± 3.86) at the experiment period of 3 month, the level of ROS and the numbers of abnormal mitochondria in morphology in the cortical neurons were obviously increased in high-dose fluorosis group(25.48 ± 6.09,20.47 ± 6.09, all P < 0.05), whereas no significant changes were found in low-dose fluorosis group(11.67 ± 3.49,6.68 ± 3.48, all P> 0.05). Furthermore, the increases in both ROS level and abnormal numbers of mitochondria were significant observed in the cortical neurons of low-dose fluorosis group (63.02 ± 8.15, 49.33 ± 8.61) and high-dose fluorosis group(65.60 ± 7.40,53.10 ± 6.95) as compared with the control group (25.26 ± 6.41,20.26 ± 6.41) at the experimental period of 6 month (all P < 0.05). The abnormal numbers of mitochondria correlated with ROS level(r = 0.93,0.81, all P < 0.05). Conclusions Taking excessive amount of fluoride results in high level of oxidative stress and impaired the balance of mitochondrial fission-fusion,which is dependent on the feeding times and doses of fluoride. The mechanism of the mitochondrial abnormalities might be associated with the high level of oxidative stress induced by chronic fluorosis.

Objective:To explore the behavior and influencing factors of mobile health (m-Health) information searching among patients with cancer, aiming to provide evidence for the provision of medical health information.Methods:A cross-sectional survey was conducted.A total of 535 patients with cancer were recruited from a cancer hospital in Zhejiang Province from September to December 2017.Measurement tools included the demographic information questionnaire, mobile health information search behavior questionnaire, mobile health information search environment questionnaire, cancer needs questionnaires-short form and ehealth literacy scale.SPSS 26.0 was used for descriptive statistical analysis, one-way analysis of variance, Pearson correlation analysis and multiple linear regression analysis.Results:The total score of mobile health information search behavior of cancer patients was (60.84±9.60), and 66.5% of participants reported that they "never" or "occasionally" searched health information via mobile.The total score of information needs was (80.99±27.86), electronic health literacy was (26.54±7.85), mobile health information search environment was (8.00±2.86). m-Health information search behavior was positively correlated with information needs ( r=0.251, P<0.01), ehealth literacy ( r=0.538, P<0.01), and m-Health information search environment ( r=0.267, P<0.01). The stepwise regression analysis revealed that the place of residence, working status, income level, ehealth literacy, mobile health information search environment and information needs were statistically significant associated with the m-Health information searching behavior among cancer patients, which accounted for 39.3% of the total variance ( F=12.151, P<0.01). Compared with patients living in the central cities, those living in the small and medium-sized cities( β=0.092, P=0.031) had higher score in m-Health information behavior.Compared with patients working on normal schedule, those took sick days ( β=0.156, P=0.017) and working fewer hours ( β=0.138, P=0.002) had higher score m-Health information behavior.Compared with patients with monthly income of 1 000-3 000 yuan ( β=-0.194, P=0.002), those with monthly income less than 1 000 yuan had higher score in m-Health information behavior.The ehealth literacy ( β=0.425, P=0.000), mobile health information search environment ( β=0.179, P=0.000) and information needs ( β=0.091, P=0.027) were positive influencing factors of m-Health information search behavior. Conclusion:Patients with cancer did not report high m-Health information search behavior.Place of residence, working status, income level, ehealth literacy, m-Health information search environment and information demand were the influencing factors of m-Health information search behavior among patients with cancer.

Objective To investigate the histological features,biological features,clinical treatment and prognosis of pancreatic acinar cell carcinoma.Methods A retrospective review of 10 patients with pancreatic acinar cell carcinoma treated in our hospital from 1999 to 2008 was conducted and the clinical features,imaging changes,pathologic feature,treatment course and follow-up data were collected.Results There were 9 men and 1 woman with a mean age of (62±8) years old.Tumors were located in the uncinate process in 1 patient,head of pancreas in 7,body and tail in 2.The median size of these tumors was 4.5 cm×4.7 cm;common bile duct and intrahepatic bile duct,pancreatic duct dilation was detected in 7 cases,and superior mesenteric vein was invaded in 2 cases.Of the 10 patients,8 received pancreaticoduodenectomy,among these 8 patients,3 had extended lymph node dissection,2 had portal vein resection and replacement;2received resection of pancreatic body and tail as well as splenectomy.Histologically,the size of these tumors were 4.0 cm×3.3 cm×3.4 cm.Macrescopically,duodenum was invaded in 5 patients,superior mesenteric vein was invaded in 2 patients and neural invasion was present in 7 cases.Lymph node metastasis was noted in 6 cases.Follow-up data was available in 9 patients and 1 patient was lost in follow-up.The survival ranged from 3 to 51 months with a median survival 18 months,and 9 patients died of tumor recurrence and metastasis after operation.Conclusions Pancreatic acinar cell carcinoma should be recognized as a distinct tumor entity and it may not be sensitive to radiotherapy or chemotherapy.The biological features of pancreatic acinar cell carcinoma should be investigated further.

Objective To investigate the clinical features,diagnosis and prognosis of solid pseudopapillary tumor of the pancreas(SPTP). Method The clinical data of SPTP cases that underwent surgical resection with a definitive histological diagnosis in Zhong Shan Hospital from 1999 to 2007 were retrospectively analyzed.Result There were 42 SPTP cases undergoing surgery in this period,including 37 females and 5 males:mean age was 37.6 years.Tumors located in the pancreatic head in 18 cases and in the body or tail in 24 cases.The most common symptom was abdominal discomfort(n=20),palpable mass (n=8).Preoperative diagnostic accuracy of MRI and CT were 93%and 31.8%,respectively.Ten cases underwent pancreaticoduodenectomy,20 cases received distal pancreatectomy,3 cases did spleen-preserving distal pancreatectomy.Tumors were simply enucleated in 8 cases.Average diameter of the tumors was 6.1 cm,34 lesions were solid,6 were solid-cystic,2 were cystic.The overall perioperative morbidity was 38.1%,10 cases developed postoperative pancreatic fistula.The mean follow-up time was 38.6 months.Except three cases that were lost to follow-up,all the other cases were alive.Four cases(2 cases had had tumor enucleation,2 had had distal pancreatectomy)developed hepatic metastases on 70、110、41、3 months after first surgery,respectively.A transarterial chemoembolization was employed in three cases,while right hemihepatectomy was performed in one case. Conclusion SPTP is an indolent tumor with low-grade biological aggressiveness.Patients had a favorable outcome after surgical treatment,but enucleation should be avoided.Patients with liver metastasis may benefit from chemoembolization and liver resection.

Objective To study the difference between intensity-modulated radiation therapy (IMRT) and three dimensional conformal radiation therapy (3D-CRT) for pelvic radiation of post-operative treatment with gynecologic malignant tumor. Methods A prospective investigation study was conducted on 183 patients of post-operative patients with whole pelvic radiation therapy of cervical cancer or endometrial cancer in Zhejiang Cancer Hospital [IMRT group (n=85) and 3D-CRT group (n=98)] from Oct. 2015 to Oct. 2016. The two groups received same dose (45 Gy in 25 fractions). Comparison of two groups with radiation dosimetry:the score according to the Radiation Therapy Oncology Group (RTOG) acute radiation injury grading standards before and after radiotherapy reaction, the score from functional assessment of cancer therapy scale-cervix (FACT-Cx) scale and expanded prostate cancer index composite for clinical practice (EPIC-CP) scale were also analyzed. Results (1) There were no significant effect with age, culture level, family economic condition and ratio of radiochemotherapy between two groups (all P>0.05). (2) Dosimetric comparison for IMRT vs 3D-CRT:the average dose of planning target volume (PTV) decreased(46.1 ± 0.4) vs(46.4 ± 0.5)Gy, V45 dose percentage increased(95.2 ± 1.0)%vs (93.3 ± 2.0)%, intestinal bag dose of V40 decreased(24.4 ± 6.8)%vs (36.5 ± 15.9)%, rectal V40 dose percentage decreased(73.9 ± 12.3)%vs (85.4 ± 8.4)%, and lower rectal V45 dose percentage(32.8 ± 13.4)%vs (71.5 ± 13.7)%, bladder V40 dose percentage decreased(55.5 ± 13.0)% vs (84.4 ± 13.0)%. Bone marrow V20 lower:(67.9 ± 5.4)% vs (79.5 ± 6.6)%, V10 lower:(82.1 ± 6.0)% vs (86.3 ± 6.6)%; there were significant differences (all P<0.05). There was no significant difference between the dose of V45 in the intestinal pouch and bladder (P>0.05). (3) Acute radiation injury classification for IMRT vs 3D-CRT:big or small intestine:Ⅱ-Ⅲreaction [13%(11/85) vs 24% (24/98); χ2=3.925, P=0.048], there was significant difference. Bladder: Ⅲ reaction [19% (16/85) vs 26% (25/98); χ2=1.171, P=0.279], there was no significant difference. Radiochemotherapy of bone marrow suppression:Ⅲ-Ⅳreaction (14/20), the incidence rate [26%(14/54) vs 31%(20/65);χ2=0.339, P=0.562], the difference was not statistically significant. (4) Quality of life scale by FACT-Cx scale in IMRT vs 3D-CRT:there were no significant difference before radiotherapy (82 ± 16 vs 85 ± 16;t=1.279, P=0.203), while there was significant difference after radiotherapy (76 ± 14 vs 71 ± 18;t=-2.160, P=0.032). EPIC-CP scale score:before radiotherapy they were (16±7 vs 15±6;t=-0.174, P=0.862) ,but after radiotherapy (18±7 vs 22± 7; t=3.158, P=0.002), there was significant difference between them. Before and after radiotherapy, the increased EPIC-CP scale of the IMRT group vs 3D-CRT group were 3 ± 4 and 6 ± 4, the 3D-CRT group was significantly higher, the difference was statistically significant (t=5.500, P=0.000). Conclusion IMRT has shown that there are a significant benefit for the post-operative patients with cervical cancer and endometrial cancer compared to 3D-CRT.

Objective To promote the diagnostic accuracy of intrapancreatic accessory spleen (IPAS).Methods The clinical data of 10 cases of IPAS admitted in Fudan University Zhongshan Hospital from Apr 2005 to Dec 2013 were retrospectively analyzed.Results There were ten cases of IPAS confirmed pathologically.Only 1 of the ten cases was diagnosed correctly and definitely with IPAS preoperatively.The other 9 cases were misdiagnosed with benign or malignant pancreatic tumors,including nonfunctional neuroendocrine neoplasms in 5 cases,pancreatic neuroendocrine cancers in 3 and pancreatic intraductal adenocarcinoma in one.All the nine misdiagnosed patients has no specific symptoms or laboratory indexes.All the IPASs located in the tail of the pancreas with the mean diameter (1.3 ±0.2) cm(0.8-2.5 cm).7 cases of IPAS show strikingly similar dynamic enhancement to the spleen on the CT scans and/or MRI.Accessory spleen around the splenic hilum was found in five cases.Conclusions Morphological study plays an important role in the diagnosis and IPAS carries parallel dynamic enhancement to the spleen on CT scans and/or MRI.IPAS should be considered as a differential diagnosis while the lesion is no more than 2.5 cm in diameter and when other accessory spleens were shown around the splenic hilum.
