BACKGROUND : Chitosan, derived from chitin, has a poor solubility which limits its application greatly. For improving its dissolubility, according to the feature that intramolecular hydroxy and amino group in chitosan are easy to be chemically modified, and functional groups are introduced to improve its solubility and functionality to widen the range of its application, which has become one of the new trend of development for investigating the application of chitosan. OBJECTIVE: To sum up the research advancements in the application and modification of chitosan in carboxylation,acylation, alkylation, etherification, etc.RETRTEVE STRATEGY: The relevant articles published in English between 1998 and 2007 were searched for in Pubmed database with the key words of "chitosan, modification", and the relevant articles published between 1998 and 2007 were searched for in Elsevier Science database with the key words "chitosan, modification" and search "derivate" within search results in English. Articles closely related to the structural modification and application of chitosan were involved, and repetitive and old studies were excluded.LTTERATURE EVALUATION: Totally 154 articles were selected, and 30 of them are accorded with the inclusive criteria,including 5 are reviews, and the others are clinical or experimental studies.DATA SYNTHESTS: The intramolecular hydroxy and amino groups in chitosan are mostly modified because they are easy to be chemically modified. Recently, reports lay particular emphasis on the modification in carboxylation, acylation,alkylation, etherification, etc. Functional groups are introduced to improve its solubility and functionality to widen the range of its application.CONCLUSTON: The water-solubility of chitosan can be improved through structural modification and introducing multifunctional group, which can also bring about much more special efficacies.

Fetal arrythmia is a common cardiac abnormality, which can be categorized into three major types: extrasystoles, tachycardia and bradycardia. Most fetal arrythmias do no harm to the fetus, but few severe fetal arrythmia, including supraventricular tachycardia, atrial flutter and conduction block do, resulting in congestive heart dysfunction, hydrops fetalis and even intrauterine death. Therefore, timely intrauterine management may help to improve the fetal outcomes. This article reviews intrauterine treatment strategies for different types of fetal arrythmia.

Objective To investigate the vaginal flora characteristics,clinical symptoms and signs of lactating women 6-8 weeks after delivery and the influence factors.Methods Two hundred and twenty-three puerpera 6-8 weeks after delivery who went to outpatient department of Peking University First Hospital for postpartum review (study group) and 200 normal non-pregnant women (control group) from April to May,2010 were enrolled into this study.All in study group were evaluated by a questionnaire regarding their symptoms,sexual behavior,breast-feeding situation and delivery mode.Vaginal secretions from upper 1/3 of vagina were collected and evaluated by vaginal microbial evaluation system.Bacterial vaginosis (BV) was diagnosed if Nugent score ≥ 7.Enumeration data between groups was compared by t test,and quantitative data by Chi-square test.Results The density of vaginal flora in study group was different from that of control group (x2 =96.302,P＜0.001) ; so did the flora diversity of two groups (x2 =69.871,P＜0.001).There was no difference between mean age of study group [(30.5 ± 3.9) years] and control group [(30.9 ± 2.4)years],P＞0.05.The cesarean section rate was 52.7％ (89/169),13 women (7.7％) had began their sexual behavior before interview,116 women (70.3％) took breast-feeding.Dominant bacteria in the vagina of lactating women were Gram-positive cocci (69/175,39.4％) and Gram-positive bacillus (54/175, 30.9％), which was different from control group (Gram-positive bacillus,180/189,95.2％),P＜0.001.The vaginal pH of study group was 5.0±0.5,which was higher than that (＜4.5) of control group.In study group,incidence of lower hydrogen peroxide level of vagina was 84.3 ％ (177/210) ; positive rate of sialidase was 6.7 ％ (14/210) ; positive rate of leukocyte esterase was 91.0％ (191/210).A large number of postpartum women had an abnormal Nugent score,most of them showed a state of intermediate BV (132/195,67.7％) or BV (8/195,4.1％),while a few patients had symptoms of BV (23.5％,33/140).Sexual behavior had no significant effect on postpartum vaginal flora.The proportion of abnormal vaginal flora in breast feeding mothers (74.1 ％,86/116) was significantly higher than that (57.1％,28/49) in artificial feeding mothers,P=0.034.Delivery mode also affected postpartum vaginal flora.Women underwent cesarean section were more susceptible to abnormal vaginal flora (77.5％,69/89) than those underwent vaginal delivery (57.5％,46/80),x2 =7.726,P=0.005.Conclusions Vaginal flora of postpartum women 6-8 weeks after delivery had significant difference from that of nonpregnant women.The incidence of asymptomatic abnormal vaginal flora was high.Breastfeeding and delivery mode are influence factors of abnormal vaginal flora.

Objective To observe the long-term effects of maternal mild hyperglycemia on the growing development and glucose and lipid metabolism in intergenerational rat offspring.Methods Streptozotocin (25 mg/kg) was administered to 14 pregnant Wistar rats intraperitoneally on the first day of gestation to induce an animal model of mild intrauterine hyperglycemia,which was successful in nine rats.Seven pregnant rats without streptozotocin intervention served as controls.Female first-generation offspring (F1) rats were intercrossed with normal male rats to obtain the second-generation offspring (F2) rats.F1 and F2 rats were divided into 8 groups:female group (group F1-G-♀) or male group (group F1-G-♂) exposed to intrauterine hyperglycemia;female group (group F1-C-♀) or male group (group F1-C-♂) exposed to intrauterine euglycemia;transgenerational female group (group F2-G-♀) or male group (group F2-G ♂)exposed to intrauterine hyperglycemia;and transgenerational female group (group F2-C-♀) or male group (group F2-C-♂) exposed to intrauterine euglycemia.Body weight of the offspring was recorded.At the age of 28 weeks,the weight of pancreas and visceral fat,fasting plasma glucose (FPG),fasting insulin,total triglyceride,total cholesterol,high-density lipoprotein-cholesterol,low-density lipoprotein-cholesterol were measured in all groups.Two sample t test was used for statistical analysis.Results (1) At 4,24 and 28 weeks old,the body weight of group F2-G-♀ [(177.3± 12.3),(314.5± 13.9) and (322.3± 16.2) g] was remarkably increased compared with group F2-C-♀ [(164.3±6.0),(290.2± 18.3) and (300.2± 16.2) g,t=-2.324,-2.584and-2.359,all P ＜ 0.05].(2) At 28 weeks,the pancreas weight and the ratio of pancreas weight to body weight of group F1-G-♀ [(0.53 ±0.05) g and (0.17±0.02)％] were decreased significantly compared with group F1-C-♀ [(0.65±0.04) g and (0.21±0.02)％,t=4.159 and 2.483,both P ＜ 0.05].The pancreas weight,ratio of pancreas weight to body weight,visceral fat weight and fat weight of mass ratio in groups F2-G-♂ and F2-G-♀ were not remarkably different from groups F2-C-♂ and F2-C-♀,respectively (all P ＞ 0.05).(3)The level of FPG at three weeks of age in F2-G-♀ group was higher than in F2-C-♀ group [(6.5±0.8) vs (4.9±1.2) mmol/L,t=-2.786,P ＜ 0.05],and it was also higher in F2-G-♂ group than in F2-C-♂ group [(6.3±0.8) vs (4.7± 1.0) mmol/L,t=-2.696,P ＜ 0.05].At 28 weeks,the FPG level was (6.7±0.6) and (8.4±2.2) mmol/L in F2-G-♀ and F2-G-♂ groups,being higher than in F2-C-♀ and F2-C-♂ groups,respectively [(5.8±0.5) and (6.2± 1.0) mmol/L,t=-2.695 and-2.337,both P ＜ 0.05].Compared with F1-C-♀ group [(0.61 ±0.10) mmol/L],the high-density lipoprotein-cholesterol level was lower in F1-G-♀ group [(0.47±0.05) mmol/L,t=2.433,P ＜ 0.05].(4) In groups F1-G-♀,F2-G-♀ and F2-G-♂,the structure of the islet cells was obviously atrophic and disordered,and β-cells were slightly decreased and distributed unevenly,but group F1-G-♂ had significantly increased β-cells with hypertrophic islet size compared with control group.Conclusions F 1 rat offsprings exposed to mild intrauterine hyperglycemia experience excessive weight gain after birth,impaired structure of the islet,metabolic abnormality,increased visceral fat weight and glucose and lipid metabolism disorder,which show intergenerational inheritance and gender differences.

Objective: To investigate the correlation between gastric acid pH value of patients with acid-related gastric diseases and the score of their life events. Methods: To evaluate the LES (life event scale) of the 108 patients with acid-related diseases were divided into 3 groups according their cluster of gastric acid pH value, group one pH 1.3 (n=37), group two pH 1.6~1.7(n=32), group three pH 2.1~4.5(n=39). Results: The LES total score and factor scores increased with the gastric acid level, the total score of the three groups were 40.0?20.6, 15.1?9.2, 6.4?6.5 respectively, the differences among the three groups were significant (F=43.26,P

Objective To establish the animal model of gestational diabetes mellitus (GDM to observe the long-term effect of maternal hyperglycemia and postnatal overfeeding on the metabolism of offsprings. Methods Streptozotocin (STZ, 50 mg/kg) was administered to Wistar rats intraperitoneally on the 5th day of gestation to induce animal GDM model. Offsprings were allocated into 3 groups: Group CP (n=8) were exposed to normal maternal hyperglycemic environment, group DP-1 (n=8) exposed to intrauterine hyperglycemia and every 8 pups breast-fed by one GMD mother and group DP-2 exposed to intrauterine hyperglycemia and every 4 pups breast-fed by one GDM mother (n=8). Weight gain between 3-10 weeks were recorded, OGTT at 10 weeks and hyperinsulinemia-euglycemia clamp technique was performed, and plasma insulin level was measured by ELISA at 11 weeks. Results Offsprings in DP-1 and DP-2 group had greater weight gain than group CP at 3-10 weeks after birth [(6.68±1.70)% and (6.03±1.85)% vs (4. 74±0.93)%, P< 0. 05], but no difference was found among the three groups in OGTT results (P> 0. 05). The baseline plasma insulin level was lower in the DP-1 group than in the DP-2 and CP group [(0. 76± 0. 37)μg/L vs (1.13±0. 25)μg/L and (1.06±0. 14)μg/L](P<0. 05). GIR60-120 was higher in DP-1 Offsprings of Wistar rats, exposed to intrauterine hyperglycemia, experience excessive weight gain at 3-10 weeks after birth. Overfeeding in early life expedites the decrease of insulin sensitivity in these offspings.

Objective To understand the clinical features, management, pregnant outcomes and prognosis of pregnant women complicated with systemic lupus erythematosus (SLE). Methods Retrospective analysis of 34 women (35 pregnancies) complicated with SLE were conducted and 26 of them were followed up for 0.5～15 years. Results (1) Out of the 35 pregnancies in these 34 women, 8 were in remission stage, 8 in the well-controlled period, 1 in active phase and 18 were primary onset (10 diagnosed during the pregnancy, and 8 after terminations) during the pregnancy. (2) Among those diagnosed during the pregnancy, 2 women in the remission group and 3 in the well-controlled group were in the active stage of SLE. The several most common clinical manifestations indicating SLE deterioration were proteinuria, fatigue, edema, hypertension, erythra and decreased serum C3. (3) In women with onset during the pregnancy, 7 (38.9%) presented with proteinuria, edema and hypertension which similar to symptoms of gestational hypertension. (4) The average maternal age of the remission group was much older than those women with onset during pregnancy [(32.4±5.5) years vs (26.6±3.9) years, P=0.034]. while the proportion of active lupus nephritis was lower than that of the later (1/4 vs 16/16, P=0.004) and the well-controlled group (1/4 vs 6/6,P=0.033) during post-partum follow-ups. Conclusions Pregnancy prompted lupus nephritis has nothing to do with maternal age, but the stage of SLE. Patients who conceived in the remission stage are the least likely to have nephritic damage. Although women with onset during the pregnancy is relatively young, they are expected to have more serious renal damage and poor prognosis.
