OBJECTIVE To investigate the phlegm etiology and the prevention measures of respiratory tract infection in 89 cases with heavy type hepatitis in hospital.METHODS From Jan 2004 to May 2007,the phlegm from respiratory tract hospital infection patients were studied retrospectively.RESULTS The main respiratory tract pathogens were the G-bacillui(44.5%),G+ cocci(23.2%),Candida albicans(16.8%),Aspergillus(9.0%) and yeast-like fungi(4.5%).CONCLUSIONS The investigation of the etiology suggests that the prevention of respiratory tract infection be the main measure to decrease hospital infection in heavy type hepatitis patients.

Objective To explore the anti-convulsion action of histamine(HA) in the central system and treatment of histamine H3 receptor(H3R) antagonists to rat model with intractable epilepsy.Methods 88 Wistar rats(12-day-old) were randomly divided into three groups:normal control group,N-methyl-D-aspartate(NMDA) group and betahistine(BH) groups(including high and low dose BH groups).Wistar rats received an intraperitoneal NMDA administration to make animal model of intractable epilepsy at infant period and toddler age.After that,the rats were observed daily for latencies and incidences to two NMDA-dependent stereotypical behaviors.The HA content of each brain region was determined with fluorimetry,and H3R were evaluated with immunohistochemical method.Results The automatisms including tail twisting and emprosthotonus seizures of(12-17)-day-old rats were observed in NMDA and BH groups.The rats,aged 18-25 d,became quiet following automatisms rather than emprothotonic.Compared with NMDA group,BH groups had longer latencies and lower incidences of tail twisting and emprosthotonus(P0.05).Conclusion The NMDA-induced model is similar to the clinical manifest of human West syndrome.It is up to animal model of intractable epilepsy at infant period and toddler age.The HA content of brain region is negatively related with seizure incidence.H3R antagonists have certain therapeutic function to intractable epilepsy in rats at infant period and toddler age.

Objective To establish a method for rapid determination of nitrate in air. Methods Nitrate in air was absorbed using Na2CO3-NaHCO3 solution and the content of nitrate in the absorption liquid was determined by ion chromatography. Results The detection limit of NO3- was 0.008 mg/m3 when the sampling volume of air was 100 L. The linear correlation coefficient was 0.999 6. The relative standard deviation of the method was less than 5% and the recovery rates was 92.0%-96.7%. Conclusion The method had good selectivity and was simple and rapid for the determination of nitrate in air.

Objective To investigate the clinic application of micro-implant anchorage in the treatment of maxil-lary protrusion malocclusion. Methods Twenty-two patients,aged 18 to 25 years old,with maxillary protrusion were divid-ed into two groups:experimental group and control group with 11 patients in each group. All patients were treated with ex-traction. Micro-screw palatal implant was used in the cases of experimental group as orthodontic anchorage ,and traditional anchorage composed of extraoral arch used in the cases of control. The cephalometric films were measured before and after treatment. Statistical methods were utilized to analyze the morphological changes of facial profile and hard tissues in both groups. Results The values of U1-NA(mm:3.08±1.18 vs 8.15±3.05) and U1-SN(101.90°±3.50° vs 117.90°±6.05°) were sig-nificantly decreased after treatment compared with those before treatment in the experimental group ( P<0.01). The value of U1-L1(123.98°±5.78°vs 103.89°±8.95°) was significantly increased after treatment (P<0.01). In control group, the values of U1-NA (mm:5.01±1.34 vs 9.12±2.13) and U1-SN(101.90°±3.97° vs 114.87°±7.69°)were significantly decreased after treat-ment. The values of U1-L1(126.01°±3.12°vs 112.98°±5.98°) and U6-PtPNS(mm:21.45±2.43 vs 18.36±2.19)were significant-ly increased after treatment (P<0.05). The value of U1-L1(19.48°±8.90° vs 13.01°±5.90°) was significantly changed in exper-imental group than that of control group, but the value of U6-PtPNS(mm:0.90±0.29 vs 3.78±0.12)was significantly changed in control than that of experimental group (P<0.01). Conclusion The maxillary protrusion malocclusion with micro-im-plant anchorage can be used as treatment for patients with maxillary protrusion that needs strong anchorage.

ObjectiveTo compare the yield rate of rats islets between different collagenase digestion groups.MethodsThe SD rats were randomly divided into two groups as following by using random digits table:collagenase P group (pancreas digested by 1 mg/ml collagenase P) and type Ⅴ collagenase group (pancreas digested by 1 mg/ml type Ⅴ collagenase).After pancreas digestion,rat islet cells in two groups were culture,purified and stained with DTZ.The mean islet number and islet equivalent (IEQ) before and after purification were measured under an inverted microscope.The viability of purified islets was assessed by fluorescence staining of aridine orange (AO) and propidium iodide (PI) under the fluorescence microscopy.After purification and culture for two days,islets function was evaluated by insulin releasing tests in the two groups.ResultsBefore purification,there was no significant difference in the islets number obtained from the pancreas between two groups (P＞0.05),but there was significant difference in the IEQ (P＜0.05).After purification,the islets number in type Ⅴcollagenase group and collagenase P group was (485 ± 113)/pancrease and (643 ± 82)/pancrease,and IEQ was (674 ± 157)/pancreas and (989 ± 126)/pancreas,respectively (P＜0.05).Islet viability in type Ⅴcollagenase group and collagenase P group was (96.13 ±1.13) ％ and (96.38 ± 0.92) ％ respectively (P＞0.05).The results of insulin releasing tests revealed there was no significant difference in islet function stimulated by hypoglycemia and hyperglycemia between two groups (P＞0.05).ConclusionTwo types of collagenase are suitable for the islets digestion in rats.The stability of digestion and yield rate of purified islets in collagenase P group are higher than in type Ⅴ collagenase group.

Objective To explore the difference involved in the activation of inflammation pathway and the plasma level of inflammatory factors in the subjects with different sorts of insulin sensitivity. Methods The study was carried out in 38 women, consisting of obesity (n = 22 ) and control (n = 16 ) groups according to body mass index. The insulin sensitivity was assessed by homeostasis model assessment of insulin resistance (HOMAIR). Plasma concentrations of interleukin-6 (II-6) and IL-1β were determined by enzyme immunoassay. Western blot analysis was used to examine total protein expression and phosphorylation levels of IκB kinase (IKK) ,inhibitor of nuclear factor-κB ( IκB ) in peripheral blood leukcocytes. Electrophoretic mobility shift assay (EMSA)was used to detect the binding activity of NFκB. Results The levels of fasting plasma insulin[62.2 ( 20.0-127. 0) pmol/L vs 19. 15 ( 14. 2-47. 8 ) pmol/L, P<0. 01], HOMA-IR[2. 32 ( 0. 76-5.49 ) vs 0.70(0.53-1.7),P<0.0l], HbA1 C[(5.42±0. 45 ) % vs ( 5.08 ±0. 38) %, P<0. 05], triglyceride[( 1.75 ±0. 68 vs 1.22 ±0. 58 )mmol/L, P<0. 05], plasma IL-6[3. 15 (0. 03-22. 2) pg/ml vs 1.26 (0. 74-6.06 ) pg/ml, P<0. 01], and IL-1 β[6. 53 ( 0. 84-36 ) pg/ml vs 3. 16( 1.48-8. 86 ) pg/ml, P<0. 01]in obesity group were significantly higher than those in control group. Compared with control group, the levels of IKKo, IKKβ expression and IκBα serine phosphorylation in obesity group were markedly increased, while the expression of IκBα was significantly reduced. Accompanied with the degradation of IκBα protein, the binding activity of NFκB in obesity group was significantly increased. Conclusions The plasma levels of IL-6 and IL-1β were significantly raised in obesity group. The activation of IKK-IκB-NFκB pathway is closely associated with the genesis and development of insulin resistance in obese subjects.

Objective To compare the recent adverse reactions caused by 131I-Metuximab (licartin) treatment via two different routes and to assess the safety and advantages of peripheral intravenous bolus of licartin for the treatment of advanced HCC.Methods Clinical data of 54 patients (45 males,9 females,age 33-80 years) with advanced HCC treated with Licartin in Tianjin Medical University Cancer Institute and Hospital from October 2010 to March 2013 were collected and analyzed.The patients were divided into vein group (n=33) with Licartin injected through peripheral vein and artery group (n =21) with Licartin injected through hepatic artery.The results of blood routine examination,liver and kidney function and thyroid function between the two groups (1 week before treatment,4 and 12 weeks after treatment) were compared.The adverse reaction rate (ARR) and adverse reaction progression rate (ARPR) were also compared between the 2 groups.Ten days after Licartin treatment,all patients underwent gamma imaging to access the drug distribution in vivo.x2 test and two-sample t test were used to analyze data.Results There were no significant differences on age,gender and TNM staging between the vein group and the artery group (t =0.721,x2=0.561 and 4.769,all P＞0.05).The vein group showed temporary drug-related leucopenia (x2=7.041,P＜0.05) and increased level of serum total bilirubin (STB;x2 =10.297,P＜0.05) 4 weeks post-treatment.Twelve weeks later,the above parameters returned to baseline.In artery group,no influence on liver and kidney functions was observed,but the numbers of WBC and PLT decreased significantly (x2 =8.949 and 8.778,both P＜0.05) and returned to baseline 12 weeks post-treatment.The ARR in patients who had normal ALT levels before treatment between the two groups was significantly different(3.33％(1/30) vs 5/19,x2=5.718,P＜0.05).No significant difference was observed on ARR in patients with normal level of other parameters,and on ARPR in patients with abnormal preoperative parameters between the two groups (x2 =0.000-2.500,all P＞0.05).The drug's in vivo biodistribution and the thyroid function between the 2 groups showed no significant difference.Conclusion The peripheral intravenous bolus administration of Licartin is safe to treat patients with advanced HCC.

Objective To investigate the value of the manipulative reduction monitored by ultrasound for the intussusception of children.Methods One hundred and three intussusception children were dynamically observed by ultrasound,and were pressed softly beginning with the head of the intussusceptum,and observed whether there was intestinal peristalsis, and whether the intussuseeptum shortened and disappeared finally.The results were analyzed based on the size of the masse, the length of the intussusceptum,and the patients' age,and compared with the X-ray high pressure air enema.Results Fifty (48.5 ％) intussusception children were recovered.The recoverability was related to the size of the mass, the length of the intussusceptum, and the age of the children (level of cooperation).Thirty-nine patients were recovered after reexamined one hour later.The recoverability of manipulative reduction monitored by ultrasound for the mass diameter less than 2.0 cm was obviously higher than that by X-ray high pressure air enema.Conclusions Manipulative reduction monitored by ultrasound could cure almost half of the intussusception children patients directly.It could decrease the number of patients who were treated with high-pressure air enema,it could relieve the pain of the children and reduce their medical expenses.It also could be acted as a screening way to other therapies like high pressure air enema.
