Objective To investigate the effects of He-Ne laser on the treatment of pericoronitis.Methods 75 clinical patients with pericoronitis were randomly divided into the experimental group and control group.Local conventional therapy was given to the two groups.The experimental group was given routine treatment with He-Ne laser local exposure for 15 minutes every day,while the control group took no other treatment.3 days and 7 days later,pain and inflammation degree were recorded by three-degree pain scoring method.Total treatment effects were evaluated under a comprehensive clinical treatment standard.Results After 3 days' treatment,78.9％ patients in the experimental group and 51.4％ patients in control group felt their pain disappeared.After 7 days' treatment,97.4％ patients in experimental group and 91.9％ patients in control group felt their pain disappeared.Treatment comprehensive evaluation showed that there were statistical significance differences between two groups (P＜0.05).Conclusion He-Ne laser treatment of pericoronitis has significant anti-inflammatory analgesic effect.

Objective To analyze the association of the morbidity,the management of blood glucose,and the prognosis of patients with hyperglycemia in the medical intensive care units(ICU).Methods Medical records of ICU patients of Renji Hospital from 2002 to 2009 were reviewed using Medical Record Inquiry System,and the data were retrospectively analyzed.Results(1)2631 subjects were included in the present study,blood glucose was determined at least once during hospitalization in 2168 of them.The incidence of hyperglycemia was 26.3%,in which 12.9% presented a known history of diabetes and 13.4% without.In the patients with diabetes history,93.2% of them received anti-diabetic treatment during hospitalization.mainly with oral anti-hyperglyeemic agents (53.0%)or subcutaneous insulin injection(24.9%).However,in the patients without diabetes history,84.4% were not treated against hyperglycemia.The mortality was increased in the latter group(30.4% vs13.9%,P<0.01).(2)In the patients with diabetes history,the mortality in patients whose blood glucose>10 mmol/L was higher than those with blood glucose≤7.0 mmol/L(20.5% vs 9.9%,P<0.05):while in the patients without diabetes history,the mortality began to rise as blood glucose>7.0 mmol/L(P<0.01).(3)Multiple stepwise regression analysis revealed that the average blood glucose level was an independent risk factor for death(OR=1.26).Conclusions The ICU patients showed a high prevalence of hyperglycemia,the management of hyperglycemia should be emphasized.Hyperglycemia in critically ill patients might be an independent risk factor of increased mortality.

Objective To investigate the suppression effects of Tripotolide (TL) on the pancreatic cancer xenograft models and angiogenesis. Methods The growth suppression effect of TL on SW1990 was determined using cell count kit (CCK-8), apoptotic cells induced by TL were examined by morphology and terminal deoxynucleotidyl transferase-mediated nick end labeling (TUNEL) assay. The inhibitory effects of TL on the growth of tumor xenografts and tumor microvascular density (MVD) were investigated. ResultsTL inhibited the growth and proliferation of SW1990 cells in a concentration-dependent and time-dependent manner. The inhibition ratios of cells treated at 160 mg/ml TL for 24 h was 50. 6%, the apoptotic rate increased from 9.6% in the control group to 45.1% (P <0.01 ). The inhibition rate of cancer xenograft growth was 89.9% when TL was intratumorally injected at the dose of 0.5 mg/kg. The expression of VEGF in tumor tissue decreased while MVD also decreased from 36.25±8.64 to 9.87±3.34 (P <0.01 ). ConclusionsTL induced prominent growth inhibition and apoptosis in human pancreatic cancer cell lines. TL.can attenuate the growth of pancreatic caner xenografts through its effect on antiangiogenesis.

Objective:To study the risk factors of salivary occult blood in Tianjin public security police, and to explore feasible oral preventive and health care measures for police officers.Methods:The public security officers from all districts and counties of Tianjin who had physical examinations at the Health Examination Center of Tianjin Public Security Hospital from March 2012 to November 2012 were selected as the research objects. A stratified cluster random sampling method was used to draw samples of 388 cases. The salivary occult blood test paper was used to detect salivary occult blood. Then the self-designed "Tianjin public security police periodontal health questionnaire" was used to collect the relevant data of the subjects, and univariate analysis and multivariate unconditional Logistic regression analysis were carried out.Results:The univariate analysis result showed that salivary occult blood was significant correlated with age, police species, history of gingival bleeding, history of halitosis, history of alcohol consumption, family history and soft food preference (all P<0.005), but it was not correlated with education level, a regular oral examination, times of brushing teeth every day, time of brushing teeth every time, smoking history, hard food preference, sweet tooth preference and carbonated drinks preference(all P>0.05). Multivariate unconditional Logistic regression analysis result showed that criminal police, age, history of gingival bleeding, halitosis, smoking history were risk factors for periodontal disease, and brushing time of 2~3 minutes was protective factor for periodontal disease. Conclusions:The public security police lack the knowledge of oral health care and have not formed good daily oral health habits. Medical workers should carry out targeted oral health education to improve the awareness of the prevention and treatment of periodontal disease.

Objective To explore the pharmacodynamics change and drug resistance of hypernormal dose fluoroquinolone in the treatment of patients with respiratory tract infection.Methods Clinical data of 120 patients with respiratory tract infection was analyzed retrospectively,and they were divided into hypernormal group (study group) and routine group (control group) according to fluoroquinolones dose.Pharmacodynamic change and drug resistance were analyzed between two groups.Results There were no significant differences in age,sex,weight and treatment time between the two groups (P ＞ 0.05),but the treatment cost in the study group was significantly higher than the control group (P ＜ 0.01).The maximum plasma concentrations (Cmax) of levofloxacin,moxifloxacin and ciprofloxacin were significantly higher than the control group,the peak time (Tmax) was significantly lower than the control group (P ＜ 0.05).Drug half-life (T1/2) showed no significant difference between two groups (P ＞ 0.05).The overall effective rate of the study group was significantly higher than that of the control group (P ＜ 0.05),and ratio of drug resistance was significantly higher than the control group (P ＜ 0.05).Conclusion Application of hypernormal dose fluoroquinolone is effective in treatment of patients with respiratory tract infection,but its drug resistance is higher,so the clinical dosage should be reasonable controlled.

Objective To measure the comprehensive geriatric assessment (CGA) in elder non-Hodgkin's Lymphoma (NHL) patients in a cross-sectional study;to compare the differences between Eastern Cooperative Oncology Group (ECOG)-performance status (PS) and CGA.Methods CGA stratification included the following 3 instrument assessments:activity of daily living (ADL);instrumental activity of daily living (IADL);comorbidity score according to the modified cumulative illness rating score for geriatrics (MCIRS-G).According to CGA and age,NHL patients,aged ≥60 years,were classified as "fit","unfit" and "frail" groups.ECOG-PS was evaluated and compared with CGA.Results According to CGA,51.6％ senior NHL patients (33 cases) were classified as "fit",12.5％(8 cases) as " unfit" and 35.9％ (23 cases) as "frail".Several comorbidities were observed in majority patients,such as cardiovascular disease,diabetes nellitus and hypertension.In the "younger aged" patients between 60 to 64ys,25％(3/12) was considered as "frail".However,this proportion increased to 42.9％ (6/14) in patients older than 80ys.Moreover,impaired CGA was observed in 38.9％(21/54) of ECOG-PS ≤1 patient.Conclusions Impaired CGA is as common as approximately half in elderly NHL patients and more than one third even in ECOG-PS ≤ 1 patients.ECOG-PS may underestimate the impaired fitness function in elder NHL patients.

ObjectiveTo investigate the clinical features of acute hepatitis E (AHE) patients with or without severe jaundice and the risk factors for severe jaundice. MethodsA retrospective analysis was performed for the clinical data of 179 AHE patients who were admitted to Shanghai Public Health Clinical Center Affiliated to Fudan University from January 1, 2018 to March 26, 2020. According to whether total bilirubin (TBil) was ＞171 μmol/L, the patients were divided into AHE-mild jaundice (AHE-M) group and AHE-severe jaundice (AHE-S) group, and the two groups were compared in terms of clinical data and laboratory markers. The t test or the Mann-Whitney U test or the chi-squared test was used for comparison, and a binary logistic regression analysis was used to identify independent risk factors. ResultsOf all 179 patients, 101 (56.42%) were found to have severe jaundice. Compared with the AHE-M group, the AHE-S group had a significantly higher proportion of male patients (80.20% vs 61.54%, χ2=7.612, P=0.006), a significantly longer length of hospital stay ［29 (19-45) days vs 18 (14-22) days, Z=-6.035, P＜0.001］, a significantly higher number of patients with liver failure (23 vs 0, χ2=18.373, P＜0.001), and a significantly poorer prognosis (P＜0.001). Compared with the AHE-M group, the AHE-S group had significantly higher baseline anti-HEV-IgM, alpha-fetoprotein, and liver elasticity (Z=-3.534, -3.588, and -4.496, all P＜0.001), significantly lower baseline CD4 (Z=-2.015, P＜0.05), significantly higher peak values of TBil, direct bilirubin, creatinine, prothrombin time, international normalized ratio, and absolute neutrophil count (Z=-11.016, -10.926, -2.726, -4.787, -4.989, and -6.016, all P＜0.01), a significantly lower peak value of gamma-glutamyl transpeptidase (GGT) (Z=-4.55, P＜0001), and significantly lower valley values of albumin, prealbumin (PA), and absolute lymphocyte count (Z=-4.685, -5.087, and -4.818, all P＜0.001). The logistic regression analysis showed that anti-HEV-IgM (odds ratio ［OR］=1.022, 95% confidence interval ［CI］: 1005-1.039, P=0.012), GGT (OR=0.995, 95%CI: 0.993-0.998, P=0.001), PA (OR=0.991, 95%CI: 0.983-0.999, P=0.02), and neutrophils (OR=1.486, 95%CI: 1.169-1.889, P=0.001) were independent risk factors for severe jaundice in AHE patients. ConclusionThere is a relatively high proportion of male patients among the AHE patients with severe jaundice, with a long length of hospital stay, a large number of patients with liver failure, and poor prognosis. Anti-HEV-IgM, GGT, PA, and neutrophils are independent risk factors for severe jaundice in AHE patients.
