Objective To investigate the intervention of Chinese herb Shengjiang San(SJS)for the imbal-ances of serum Th1/Th2 cells and related regulatory factors in sepsis patients. Methods Fifty-five sepsis patients were randomly divided into two groups:conventional treatment group of 27 cases and SJS group of 28 cases. Nine cases of healthy volunteers were enrolled as control group in the study. Cases of conventional group were treated with western medicine only and cases of SJS group were treated with both western medicine and Chinese herb SJS (100 mL twice one day). The therapy course of both groups was 3 days. Score of Chinese medical syndromes ,se-rum level of leukocyte count,C reactive protein(CRP)and procalcitonin(PCT),serum T-bet,GATA-3,Th1&Th2 cells in the proportion of whole CD4+Th cells and Th1/Th2 ratio were compared respectively in each group be-fore and after treatment. Results There were significant differences between SJS group and conventional group in score of Chinese medical syndromes,serum level of leukocyte count,T-bet,GATA-3,Th1&Th2 cells in the pro-portion of whole CD4+Th cells and Th1/Th2 ratio(P<0.05 or P<0.01). There were no significant differences be-tween the two groups in serum level of CRP,PCT and GATA3. Compared with control group,there were signifi-cant differences in all indicators except GATA3 of the two groups(P<0.01). Conclusion Chinese herb Shengji-ang San has an effective benefits to Chinese medical syndromes,inflammatory reaction,the imbalance of serum Th1/T2 and related regulatory factors(T-bet&GATA-3)in sepsis patients.

Objective To understand and analyse the epidemic status of human intestinal nematode infection in Jiangsu Province, so as to provide basis for making control measures. Methods The typical thirty-nine spots in thirteen counties among the sampling spots of National Investigation on Distribution of Human Parasites in 1990 were selected and investigated according to the Methods of National Investigation Scheme on Human Principal Parasites in 2004. Results The total prevalence was 3.88%, which decreased by 46.92% compared with the investigation in 2002 (7.31%). The infection rates of hookworm, Ascaris and Trichuris were 1.14%, 1.06% and 1.73%, respectively, and the proportion of light infection was 91.75%. The rate of multiple infections was 9.40%. The proportion of hookworm infection was 78.06% in Southern Jiangsu and the proportion of Ascaris or Trichuris was 89.03% in Northern Jiangsu. The infection rate of Enterobius was 3.72% among children aged less than 12 years. Conclusions The prevalence of intestinal nematodes has decreased to lower level in Jiangsu Province. The difference of prevalence in different regions has a relationship with the disease control and social-economic, culture and health levels. The principal control work should be still put in the northern part of Jiangsu Province. The preschool children and the middle and old age peasants are high-risk population. The different control measures should be taken in accordance with the situation of different regions in the future.

Objective To explore the relationships between the sleep/wake-up patterns and temperament in preterm infants.Methods The developmental characteristics of sleep/wake-up patterns and temperament in preterm infants aged 4 months at corrected gestational age in their own home environments were described.The 23 relatively low-risk preterm infants were enrolled in this study.The sleep/wake-up data was collected with actigraphy.The temperament was assessed by Chinese Infant Temperament Questionnaire.Results Among the 23 infants,there were 13 coordinated difficult(D) type and 10 coordinated easy(E) type.The number of night wake-up in the coordinated D-type preterm infants[(2.78 ±0.01) times] were significantly more than that of coordinated E-type ones[(2.60 ± 0.03) times] (t =3.285,P =0.001).The longest continuous sleep time of coordinated D-type preterm infants [(4.20 ± 1.21) h] was significantly less than that of coordinated E-type ones[(4.41 ± 1.14) h] (t =3.374,P =0.001).There were no significant differences in daytime sleep duration,the number of naps,bedtime,sleep latency,nighttime sleep duration,the 24 hour sleep duration and morning awaking time between the two groups (all P ＞ 0.05).After the sex factor was controlled,there was a positive correlation between emotional nature and sleep latency at night (r =0.599,P =0.032).There was also positive correlation between persistence and the number of naps in daytime (r =0.439,P =0.035).Conclusions Preterm infants with different temperament types have different number of night wake-ups and the longest continuous sleep time.The emotional nature and persistence are associated with sleep latency at night and number of naps in daytime respectively.The parents of preterm infants should change their child rearing behaviors to improve sleep quality of the preterm infants.

Objective To evaluate the clinical effect of the lung protective ventilation combining with Re-duning injection on the acute lung injury (ALI). Methods 59 patients with ALI were randomly divided into the lung protective ventilation group (control group, n =30) and the lung protective ventilation wmbined with Reduning injection group(experimental group,n = 29) ,and the changes of vital signs,RR,blood gas analysis,and so on were observed. The comparison between PaO2 and PaO2/FiO2 was carried out. The efficacy and the mortality rate were evaluated. Results Lung injury in 21 cases of experimental group were improved after applied Reduning treatment(72. 41%),there was a significant difference ( P < 0.05) with that of 14 cases in control group (46. 67% ) ; PaO2 increased, PaO2/FiO2 significantly increased in experiment group,there were significant difference compared with those of control group(P <0. 01). The mortality rate in the experimental group was 24.14% ,there was a significant differ-ence(P<0.05) compared with the mortality of 50. 00% in control group. Conclusion Reduning treatment could, improve the pulmonary function in lung protective ventilation to cure ALI,reducing the mortality rate as well.

Objective To understand the present status of human parasitic infections and their characteristics in rural areas of the southern part of Jiangsu Province, to provide basis of making practical control measures.Methods Four thousand and eighty-two people were examined with stool tests and those people were distributed in 8 slected spots in the southern part of Jiangsu Province,according to the methods of national investigation scheme on human principal parasites. Results The avarage infection rate of parasites was 6.71%. The male and female infection rates of parasites were 4.77% and 8.42%,respectively. There were significant differences (P

Objective To understand the status and characteristics of principal human parasitic infections in rural areas of Jiangsu Province in order to provide basis for decision-making of practical control measures. Methods The survey data of principal human parasites in 58 sample sites of 19 counties (cities or areas) in Jiangsu Province were analysed on family clustering by G test, according to the methods of National Investigation Scheme on Principal Human Parasites. Results The infection of Ascaris lumbricoides, hookworm, Trichuris trichinra and Clonorchis sinensis in the province had obvious family clustering, while those in each county (city or district) appeared different states in some-points with the changing of parasitic infection rates and infection degrees. Conclusions The infection rates and infection degrees of principal human parasites decrease obviously in Jiangsu Province. The family clustering is disappearing with the dropping of them. Chemotherapy in family and health education should be strengthened to consolidate the control results in future.

Objective To investigate and analyze the changes of Ascaris lumbricoides infection in rural residents of Jiangsu Province during 13 years and its influencing factors in order to provide the basis of making practical policies for ascariasis control in future. Methods The data were analyzed about the rates of Ascaris infection and mass chemotherapy, per capita income, and the rates of the use of running water and hygienic toilets in the southern part, the middle part and the northern part of Jiangsu Province from 1990 to 2002, and the main influencing factors for Ascaris infection were explored. Results The prevalence rate of Ascaris infection decreased continuously during 13 years, from 39.51% to 2.14%, and the decrease rate was 94.58%. In 2002, the infection rate was the lowest, only 0.41%, decreased by 98.92% in the middle part of Jiangsu Province, and the infection rate was the highest, 5.09%, decreased by 89.97% in the northern part of Jiangsu Province. The accumulated rates of mass chemotherapy were 159.00% in middle part of Jiangsu Province,103.00% in the southern part of Jiangsu Province and 105.00% in the northern part of Jiangsu Prvince.The per capita income, the use of running water and hygienic latrines increased gradually from the northern part to the southern part and there were significant differences in the 3 survey regions. Conclusion The Ascaris infection rate is influenced by mass chemotherapy, economics and health conditions in rural residents, especially the mass chemotherapy.

Objective To determine the correlation between central macular thickness (CMT) and the visual function in patients iwht macular edema (ME). Methods The clinical data of 42 eyes of 40 patients with ME which were examined by optical coherence tomography (OCT) and microperimetry (MP-1) wereretrospectively analyzed. In 40 patients (42 eyes), diabetic ME (DME) was in 27 eyes,branch retinal vein occlusion was in 11eyes, and central retinal vein occlusion was in 4 eyes. All of the eyes had undergone OCT,MP-1 and best-corrected visual acuity (BCVA) test. Central macular thickness (CMT) was measured by fast macular scans using OCT. Retinal sensitivity (MS) and fixation patterns were evaluated by Mp-1.The position was chosen :2 disc diameters (DD) temporal to the disc and one third of a DD inferior to the centre of the disc. Results The correlation between CMT and BCVA is not significant (r=-0. 429, P=0. 069) as well as the correlation between CMT and MS (r=-0. 433,P=0. 058). The difference of CMT between the unstable and stable group was significant (F = 3. 262, P = 0. 039). The difference of CMT between the central fixation group and preferred retinal locus (PRL) group was significant (F=3. 173,P=0. 044). Conclusions BCVA and MS have no significant correlation with CMT. When CMT increases, the fixation stability decreases, fixation location, changes, and PRL occurs.

Objective To establish a Juema minipig model of myocardial infarction, to evaluate the clinical indi?ces in the model pigs, and to explore the relationship between gene expression and metabolic decompensation. Methods 13 male Juema minipigs were randomly divided into control (Sham, n=5), myocardial infarction (MI, n=5) and normal control (for evaluating the recovery condition after surgery, n=3) groups. In the MI group, the ligation was done at the left descending coronary artery around the 1/3 distance to heart apex. Four weeks after the surgery, the cardiac function and serum biochemistry was analyzed. The histological changes and gene expression profiles in the myocardium in the peri?infarct area were exanimated. Results Ultrasonic images showed that the infarction was formed, the ejection fraction and fraction shortening were significantly reduced in the MI group ( ~32% and ~40% less than those of the sham group). Histological examination showed that myocardial fibers at the peri?infarct area were broken, dissolved, and there was con?nective tissue hyperplasia with increased neutrophil and lymphocyte infiltration. Microarray analysis revealed that two myo?cardial remodeling and pathology mediating pathways, three inflammation?related pathways, and 8 metabolic pathways ( in?cluding fatty acid, amino acid, and glucose metabolic pathways) were significantly changed. Conclusions We have suc?cessfully established a Juema minipig model of myocardial infarction. The less branches of the left descending coronary ar?tery allow us to establish a stable model by surgery with comparable characteristics in the clinic indices. The results of this study provides useful reference characteristics of an animal model with characteristic changes in the peri?infarct area.

Objective To evaluate the value of hysteroscopy in elder women with abnormal uterine bleeding (AUB) and asymptomatic postmenopausal women with a thickened endometrium.Methods Fifty-three cases in the AUB group and seventy-eight cases in the endometrial hyperplasia group underwent hysteroscopy examination and hysteroscopy-guided biopsy,then the hysteroscopic and histopathological results were compared between the two groups.Results Of the 131 cases,the normal endometrium accounted for 29.8％ (n=39),endometrial polyp for 49.6％ (n=65),submucous myomas for 4.6％ (n=6),hyperplasia endometrii for 6.1％(n=8) and endometrial carcinoma for 9.9％ (n=13).Both the AUB group and theendometrial hyperplasia group had 8 cases of endometrial carcinoma (15.1％,6.4％,respectively).For the diagnosis of normal endometrium with hysteroscopy,the sensitivity,specificity,positive predictive value (PPV) and negative predictive value (NPV) were 88％,97％,94％ and 95％,respectively,in the AUB group,versus 82％,95％,86％ and 93％,respectively,in the endometrial hyperplasia group.For the endometrial polyps,hysteroscopy showed a sensitivity,specificity,PPV and NPV of 100％,79％,74％,100％,respectively,in the AUB group and 98％,88％,92％,97％,respectively,in the endometrial hyperplasia group.For the endometrial cancer,hysteroscopy had a sensitivity,specificity,PPV and NPV of 75％,100％,100％ and 96％,respectively,in the AUB group;while in the endometrial hyperplasia group,the sensitivity was 80％,the specificity and PPV were 100％,and the NPV was 99％.Conclusions In elder females,hysteroscopy allows for an accurate diagnosis in endometrial disease,and hysteroscopically directed sampling is mandatory,even if the uterine cavity appears normal at hysteroscopy,to rule out endometrial neoplasms.
