OBJECTIVE: To determine the expression profile of microRNA (miRNA) in peripheral blood mononuclear cells (PBMC) and immune factors in pregnant women with hepatitis B virus (HBV) infection. METHODS: A total of 182 pregnant women infected with HBV were randomly selected, with 40 healthy pregnant women and 35 non-pregnant women as controls. High-throughput sequencing was used to detect RNA in the PBMC of all subjects. Indirect ELISA method was used to determine the changes of cytokines in peripheral blood samples. RESULTS: Compared with the control group, 18 differentially expressed miRNA were identified in those with HBV infection (P< 0.01). Among these, miR-3607-3p, miR-20a, miR-1296, miR-153-1 and miR-X4 may directly regulate the transcriptional level of target genes including IL-10, IL-18, IL-16, MCP-1, NUP50 and CCR1. Meanwhile, peripheral blood cytokines IL-10, IL-18, IL-16 and MCP-1 were significantly increased in those with HBV infection (P<0.01), with the expression level of IL-16 and MCP-1 being strongly correlated with the viral load. CONCLUSION The expression profiles of miRNA in PBMC and cytokines in peripheral blood can change significantly during pregnancy, both may be involved in the immune response to HBV infection.

Sichuan Province is located across several major geomorphic units,such as the Qinghai Tibet Plateau,Hengduan Mountains,the Yunnan-Guizhou Plateau,Qinling Bashan Mountains,and Sichuan Basin.The complex ecological environment has created rich plant species.Based on the results of the fourth national survey of traditional Chinese medicine resources in Sichuan Province,according to the plant catalog in the,The results indicate that Sichuan has a total of 42 families,65 genera,and 116 species(including sub species)of medicinal plants under national key protection,there are 9 species such as lotus leaf fern under first level protection,and 107 species such as golden haired dog under second level protection.The distribution of rare and endangered medicinal plants in Sichuan Province has obvious regional characteristics,with the highest distribution in Leshan and Ganzi,and obvious vertical distribution.There are as many as 57 species distributed in high-altitude areas such as Ganzi Prefecture and Aba Prefecture.The endangered reasons for the key protected medicinal plants in Sichuan Province are mostly caused by human destruction and environmental damage.It is suggested to strengthen the protection of rare and endangered medicinal plant resources and develop and utilize them reasonably.

Objective:To investigate the clinical characteristics and surgical treatment of enteric Behcet′s disease with acute abdomen.Methods:The clinical data and follow-up results of 9 patients with enteric Behcet′s disease with acute abdomen treated surgically were analyzed retrospectively.Results:All patients in this group had abdominal pain, with bloody stool in one case, failure to exhaust and defecation in 1 case. Physical examination revealed abdominal mass in 2 cases, peritonitis sign in 5 cases and tenderness of the right lower abdomen in 1 case. The causes of operation were pathological perforation of ileocecal region, pathological perforation of small intestine, acute appendicitis, ileum fistula, intestinal stenosis and obstruction and massive hemorrhage of lower digestive tract.In this group, laparotomy or laparoscopy were done in these cases, including ileocecal resection in 2 cases, partial resection of small intestine in 3 cases, laparoscopic appendectomy in 1 case and right colon colectomy in 3 cases. Incision infection occurred in 1 case, anastomotic leakage in 1 case and adhesive intestinal obstruction in 1 case occurred after operation. The median follow-up time of 8 cases was 7.5 years, and Behcet′s disease recurred in 4 cases, but no recurrence of enteric Behcet disease was found.Conclusions:Intestinal perforation, bleeding and obstruction are the main causes of intestinal Behcet′s disease with acute abdomen, and emergency surgery is an important means of treatment, moreover, nutrition support and drug therapy are the important supportive therapy to control this disease.

Objective To investigate the effect of cardiopulmonary bypass (CPB)on platelet inhibition rate(INHAA) and Aspirin resistance (AR) after coronary artery bypass grafting (CABG)surgery.Methods A total of 114 patients undergoing CABG surgery were divided into two groups:on-pump group(n=54)and off-pump group(n=60).Aspirin treatment(100 mg/d)was paused 7 days before surgery and continued 6 hours after surgery.INHAA was detected and calculated by using thrombelastography(TEG)at 6 hours after taking the last dose of aspirin before surgery(T0),12 hours (T1),5 days(T2),10 days (T3) and 15 days (T4) after surgery respectively.The incidence of AR was calculated.Results There was no significant difference in the overall INHAA between the two groups of on vs.off-pump(F =0.336,P =0.563),while the differences of INHAA index at each time point was statistically significant between two groups of on vs.off-pump(F =95.519,P =0.000).There was an interaction effect of timing and grouping(F =15.500,P =0.000).In comparison of INHAA between the two groups of on vs.off-pump at each time point,INHAA was higher in on-pump group than in off-pump group at T1 (P＜0.05),while INHAAbecame lower in on-pump group than in off-pump group at T2 (P＜0.05),and there was no statistical difference in INHAAbetween the two groups at T3 and T4 (P ＞0.05).In the on-pump group,the total difference of INHAA at different time points was significant (P＜0.05),and the INHAA was lower at T2 than at T1,T3,T4 (P＜0.05).In the off-pump group,the total difference of INHAA between different time points was significant(P＜0.05),and the INHAA was lower at T1 than at T2,T3,T4 (P＜0.05).In comparison of AR incidence after CABG surgery between two groups of on vs.off-pump at each time point,the incidence of AR was lower in on-pump group than in off-pump group at T1 (P ＜ 0.05),while there were no statistical significance between two groups of on vs.off-pump at T2,T3 and T4 (P＞0.05).In comparison of AR incidence after CABG surgery between two groups of on vs.off-pump at each time point,the incidence of AR was lower in on-pump group than in off-pump group at T1 (P ＜0.05),while there were no statistical significance between two groups of on vs.off-pump at T2,T3 and T4 (P ＞ 0.05).Conclusions The increase of platelet inhibition rate and aspirin resistance occurs in early period after CABG surgery.The platelet inhibition rate is higher and aspirin resistance rate is lower in on-pump group than in off-pump group at 12 h after surgery,and the platelet inhibition rate is lower at 5 days after CABG surgery in on-pump group than in off-pump group.CPB has little effect on the platelet inhibition rate and on the incidence of AR after 5 days of CABG surgery.

OBJECTIVE: To investigate the clinical effect of eruption guidance appliance in the treatment of anterior cross bite in mixed-dentition children. METHODS: In the study,10 mixed-dentition children with anterior cross bite, totally 12 incisors, were selected. Alginate was used to take upper and lower dentition impression and make a hard plaster model,which served as the eruption guidance appliance for treatment. The pre- and post-operative dental casts were digitized with SmartOptics Activity 880 scanner,and the three-dimensional overlapping models were obtained by reverse engineering software,Geomagic Studio 2012,then the three-dimensional movements of the upper and lower incisors were analyzed using Imageware 13.2 software. The overbite and overjet were analyzed using the same methods. Measurement with copper wire was used to analyze the upper and lower arch length. Space analysis was the result by the sum of crown width minus the arch length. The crown width of unerupted permanent teeth was according to X-ray method to predict. The SPSS 17.0 software was used to analyze the pre- and post-operative measurements of the same child. The normality test of the measured data showed that it conformed to the normal distribution. Therefore,the t test and double side test were used,and the significance level was 0.05. RESULTS: The course of treatment was (5.6±2.7) months. During orthodontic treatment, the upper incisors moved mainly labially (P<0.001) in three-dimensional displacement, and the lower incisors moved mainly the same direction (P=0.025). During the treatment of eruption guidance appliance,the average overbite decreased (1.01±0.9) mm (t=-3.531, P=0.006), and the difference was statistically significant. There was no statistically significant difference between the pre- and post-operative average overjet (t=0.771, P=0.460). The severity of crowding in upper arch decreased (1.9±0.99) mm (t=-6.042, P<0.001),and that in lower arch decreased (1.9±0.74) mm (t=-8.143, P<0.001), both of the differences were statistically significant. CONCLUSION The anterior cross bite in mixed dentition could be corrected by eruption guidance appliance, and at the same time, the normal overjet and overbite were established, and the teeth were aligned.
