Objective: To learn the characteristics of adolescent pregnancy in Wenzhou from 2015 to 2019, so as to provide basis for protecting adolescent physical and mental health. Methods: Data of demographic characteristics, pregnancy and delivery outcomes of the women aged under 19 years ( adolescent pregnant ) and 20 to 34 years ( right-age pregnant ) who delivered in Wenzhou from 2015 to 2019 were collected from Wenzhou Maternal and Child Health Information Management System. The incidence of pregnancy complication, comorbidity and adverse delivery outcomes of adolescent pregnant women was compared with that of right-age pregnant women. Results: Among 536 753 parturients reported in Wenzhou from 2015 to 2019, there were 22 419 ( 4.18% ) of adolescent pregnancy and 430 163 ( 80.14% ) of right-age pregnancy. The average age of adolescent pregnant women was (18.11±0.82) years ( range, 10-19 years ). The majority of adolescent pregnant women were migrant population (19 437 cases, 86.70%), had an education level of junior high school and below ( 18 594 cases, 82.94% ), and had no occupation (19 192 cases, 85.61%). The incidence rates of anemia, gestational diabetes, postpartum hemorrhage, perineal laceration and premature delivery in adolescent pregnant women increased from 2015 to 2019 ( all P<0.05 ). The incidence rates of gestational diabetes, anemia, gestational hypertension, placental abruption, postpartum hemorrhage, perineal laceration, premature delivery, low birth weight, fetal death and stillbirth were 1.65%, 11.76%, 0.19%, 0.26%, 3.19%, 24.52%, 6.03%, 5.53%, 0.50% and 0.04% in adolescent pregnant women, which were significant different from 5.49%, 8.94%, 0.13%, 0.01%, 0.17%, 23.46%, 4.66%, 3.08%, 0.26% and 0.01% in the right-age pregnant women, respectively ( all P<0.05 ). Conclusions The adolescent pregnant population in Wenzhou are mainly migrant population with lower education level and no occupation. The incidence rates of pregnancy complication, comorbidity and adverse birth outcomes in adolescent pregnant population are higher than those in right-age pregnant population, and are increasing year by year.

OBJECTIVETo explore the effect of Buzhong Yiqi decoction on PI3K/AKT signaling pathway in spleen, stomach and lung of nude mice with lung adenocarcinoma transplantation tumor.

METHODTotally 60 nude mice were randomly divided into the blank control group, the tumor-bearing control group, the cisplatin group, the low-dose Buzhong Yiqi decoction group, the middle-dose Buzhong Yiqi decoction group and the high-dose Buzhong Yiqi decoction group. After the corresponding interventions, efforts were made to measure the transplanted tumor volume and calculate the tumor inhibiting rate. The immunohistochemical method and real time PCR were used to detect the expression of PI3K and AKT level in nude mice spleen, stomach and lung.

RESULTBuzhong Yiqi decoction of different concentrations combined with cisplatin could inhibit the growth of the transplanted tumor, with the strongest inhibitory effect in the middle-dose Buzhong Yiqi decoction group and the high-dose Buzhong Yiqi decoction group. All of the expressions of PI3K and AKT protein and gene in the spleen, stomach and lung increased, with the most significant increase in the tumor-bearing group. Along with the increase of the concentration of cisplatin and Buzhong Yiqi decoction, the expressions of PI3K and AKT gradually reduced. Compared with the tumor-bearing control group, there were statistical differences in spleen and stomach tissues (P < 0.05). Compared with the cisplatin group, the middle-dose Buzhong Yiqi decoction group and the high-dose Buzhong Yiqi decoction group showed statistical differences (P < 0.05), but without statistical difference compared with the blank control group.

CONCLUSIONAmong nude mice with lung adenocarcinoma transplantation tumor, the PI3K and AKT protein and gene expressions in spleen, stomach and lung tissues increased, which might indicated the effect of cisplatin and Buzhong Yiqi decoction in reducing PI3K and AKT expressions and the relations between the reduction degree and the concentrations of Buzhong Yiqi decoction. Cisplatin combined with Buzhong Yiqi decoction could decrease the PI3K and AKT protein and gene expression in spleen, stomach and lung, and make the pathway closer to normal, so as to protect the functions of spleen, stomach and lung, there may be target spots of Buzhong Yiqi decoction in PI3K/AKT signal pathway.

OBJECTIVETo analyze the reversal effect of Buzhong Yiqi Decoction (BYD) on multidrug resistance of human adenocarcinoma of lung cell line A549/DDP, and to study its effect on the expression of survivin by using serum pharmacological methods in vitro. Methods Totally 24 SD rats were divided into the high, medium and low dose groups, and the blank control group by randomized controlled method. The high dose BYD containing serum (1. 134 g/mL, 2 mL), the middle dose BYD containing serum (0.576 g/mL, 2 mL), and the low dose BYD containing serum (0.284 g/mL, 2 mL) were prepared. The inhibitory effects of different dose and concentrations BYD on the proliferation of A549 and A549/DDP cells were detected by MTT assay, and the drug resistance reversal fold was calculated. The expression of Survivin in the two cell strains were detected respectively by immunohistochemical assay, Western blot, and immunofluorescence method.

RESULTSBYD containing serum showed obvious inhibitory effect on the growth of A549 and 549/DDP. The inhibition rates of 10% dose groups were higher than those of 5% dose groups. Besides, it gradually increased along with increased concentrations. Compared with 10% blank control group, the inhibition rate increased in 10% middle and low dose groups (P <0.05). After acted with 10% middle dose BYD containing serum, IC50, of A549 and A549/DDP were both reduced (P <0.05), reversal fold (RF) both increased. Its reversal ratio on A549/DDP cells was 2. 46, decreasing the resistance of A549/DDP to DDP. Compared with A549 in the same group, the expression of Survivin was detected to decrease by immunocytochemical assay, Western blot, and immunofluorescence method (P<0.05). Compared with 10% blank control group, the inhibition rate decreased in 10% middle dose group (P <0. 05).

CONCLUSIONS10% middle dose BYD containing serum could significantly inhibit the apoptosis of A549 and A549/DDP. Besides, it could moderately reverse the multidrug resistance of A549/DDP cells to DDP possibly through reducing the intracellular expression of Survivin and enhancing the sensitivity 549/DDP to chemotherapeutics.

OBJECTIVETo study whether co-stimulatory molecule CD40 of alveolar macrophage (AM) participated in the occurrence and development of silicosis, and to explore the intervention of Yiqi Huoxue Decoction (YHD) in the fibrosis of silicosis patients.

METHODSTotally 46 silicosis inpatients and outpatients were recruited and randomly assigned to the Western treatment group (A) and the Chinese medicine (CM) treatment group (B), 23 in each group. Patients in Group A received routine symptomatic treatment such as anti-inflammation, phlegm resolving, anti-spasm, and asthma relief, and so on. Patients in Group B additionally took YHD, one dose daily for 14 successive days. Besides, another 18 patients with chronic cough and sense of laryngeal foreign bodies were recruited as the normal control group, who had no obvious lesion confirmed by bronchofi6roscope and clinical diagnosis of the lung. They were treated by symptomatic supporting treatment. The alveolar lavage fluid was collected from all patients and isolated, and AM cells were cultured. The level of CD40 mRNA was detected by RT-PCR. The expression of CD40 protein was detected by Western blot.

RESULTSCompared with the normal control group, expression levels of CD40 mRNA and CD40 protein significantly increased in Group A (P < 0.01). Compared with Group A, expression levels of CD40 mRNA and CD40 protein significantly decreased in Group B (P < 0.01).

CONCLUSIONSHighly expressed co-stimulatory molecule CD40 of AM might participate in pulmonary fibrosis. YHD could hinder its roles, inhibit the progression of fibrosis, thereby playing an interventional role of treatment.

OBJECTIVETo investigate the factors affecting the survival and to predict the survival time of glioma.

METHODSGraph method was applied to fit the type of probability distribution of patients' postoperative survival time. As one suitable model, Weibull regression model tested by residual analysis was used to identify prognostic factors for postoperative survival and to predict patients' post-operative survival time.

RESULTSIn multivariate analysis of Weibull regression model, following characteristics showed significant influence on postoperative survival time including: sex, age, epilepsy, type of glioma, density of glioma, type of surgery, times of surgery and mode of postoperative therapy. According to predictive value, patients were clustered into three groups. The survival probability of one year for the first group was less than 50% and that of five years for the second group about 50%, for the third group around 80%.

CONCLUSIONSex, age, epilepsy, type of glioma, density of glioma, type of surgery, times of surgery and mode of postoperative therapy were important risk factors and Weibull regression model might help to predict patients' postoperative survival time.

Objective To design a multiplex PCR for simultaneous identification and toxigenic type characterization of Clostridium difficile isolates. MethodsThree pairs of primers were designed for the amplification of a species-specific internal fragment of the tpi( triose phosphate isomerase) gene, an internal fragment of the tcdB ( toxin B) gene, and an internal fragment of the tcdA ( toxin A) gene. Twenty-one standard strains including Clostridium difficile ATCC 9689 and 47 isolates of Clostridium difficile were applied for the assessment of detection limit, specificity and detections of the multiplex PCR, respectively. Toxin A and Toxin B of 47 isolates were analyzed by ELISA. ResultsThe detection limit for DNA concentration of the multiplex PCR was 0.5 pg/μl. The specificity was determined to be 100％. Among the results of 47 isolates detected by multiplex PC R, 37 strains were tpi ( + )/tcdA (+)/tcdB ( + ), 10 strains were tpi ( + )/tcdA (-)/tcdB ( - ). Tpi ( + )/tcdA ( - )/tcdB ( + ) was not found. The toxin detection of 47 isolates by ELISA showed that 20 isolates were positive and 27 isolates were negative. Twenty isolates of toxin (+) by ELISA were all tpi( +)/tcdA( +)/tcdB(+) by multiplex PCR. ConclusionThe multiplex PCR method combined diagnosis and toxigenic type characterization contributes to the diagnosis for Clostridium difficile infection.
