Objective To investigate the effect and mechanism of metformin on endometrial carcinoma subline of progestin-resistance and find whether metformin could regulate progestin-resistance in endometrial carcinoma. Methods Ishikawa endometrial carcinoma cells were cultured for a long period in the presence of the synthetic medroxyprogesterone 17-acetate (MPA) to generate a subline refractory to the growth-suppressive effects of MPA,named Ishikawa/MPA cells. The effect of MPA (1, 5, 10, 20, 40 and 60 μmol/L) or metformin (1, 10, 20, 40, 60, 70 and 80 mmol/L) on proliferation of the Ishikawa/MPA and parental Ishikawa cells was detected by cell counting kit-8 (CCK-8) method. Western blot was used to detect the effect of metformin and(or)MPA on the expression of PR-B in the Ishikawa/MPA and Ishikawa cells. Results The Ishikawa/MPA showed that growth stimulation rather than inhibition in the Ishikawa cells after low MPA concentration treatment. The doubling time of Ishikawa/MPA cell lines were (43±4) hours and that of Ishikawa cell line were (47 ± 3) hours. No changes in doubling time were observed (t=0.349,P=0.572). Low concentration (1 and 5μmol/L) of MPA could promote the growth of Ishikawa/MPA cells (by 3% and 13%). High concentration (10, 20, 40 and 60 μmol/L) of MPA could inhibited the growth of Ishikawa/MPA cells (by 4%, 3%, 9%and 40%) and the growth of Ishikawa cells (by 41%, 55%, 65%and 66%). At the same concentration, the difference of inhibition rates between the two cell lines were statistically significant (P<0.01). Metformin (1, 10, 20, 40, 60, 70 and 80 mmol/L) could inhibite the growth of Ishikawa/MPA (by-10%, 20%, 56%, 89%, 97%, 98%and 99%) greater than those in parental Ishikawa cells (by-6%, 19%, 37%, 54%, 70%, 72%and 83%), and the inhibitory effect was dose-dependent manner. Western blot assay showed that for Ishikawa cells, the protein expression levels of PR-B in metformin group and MPA+metformin group were respectively (53.5±4.0)%and (37.7±5.2)%, which were higher than that in the control group [(23.4 ± 3.0)%], and there were significant the differences (P<0.01). For Ishikawa/MPA cells, the protein expression levels of PR-B in metformin group and MPA+metformin group were respectively (38.6 ± 1.7)%,(36.3 ± 2.5)%,which were higher than those in the control group [(6.4 ± 1.6)%], and there were also significant differences (P<0.01). Conclusion Metformin may regulate the progestin-resistance in endometrial carcinoma by increasing the expression of PR-B.

Objective To identify the species of Biomphalaria snails collected in Shenzhen reservoir,based on the mitochondrial 16S rDNA sequences.Methods The 16S rDNA fragments were amplified by PCR from the genome DNA of Biomphalaria snails,and inserted in plasmid pMD-18T for sequencing.The sequence of 16S rDNA fragment and its phylogenetic relationships with those of other species of Biomphalaria snails were analyzed with BLAST and MEGA4 software.Results The amplified 16S rDNA fragment of the Biomphalaria snails was about 466 bp in length.As aligned with the corresponding sequences of the related Biomphalaria species,the identity of nucleotides was 99％ with 1 isolate of Biomphaltria straminea (B.straminea),98％ with 3 isolates of B.kuhniana,95％ with 1 isolate of B.intermedia,and 94％ with 1 isolate of B.edisoni.Based on the 16S rDNA sequence,the results of phylogenetic analysis with neighbor-joining (NJ) and unweighted pair-group method with arithmetic means (UPGMA) indicated that the snails had close genetic relationships with the B.straminea isolate (Genbank accession NO.AY030213.1) Conclusion The Biomphalaria snails collected in Shenzhen reservoir could be classified as B.straminea based on the characteristics of 16S rDNA sequence.

On August 2nd, 2014, 35 patients with extremely severe burns involved in August 2nd Kunshan factory aluminum dust explosion accident, including 18 males and 17 females, aged from 21 to 50 years, were admitted to our unit. According to the patient′s condition, the rescue members divided the participants into groups according to their characteristics, and used the multi-disciplinary cooperative treatment and management mode of integrating critical care medicine, anesthesia, traditional Chinese medicine, rehabilitation, and nursing led by burn medicine. Totally 27 patients were successfully treated, with a success rate of 77.14%.

The treatment of mass burn patients is related to social stability, life saving, and disability reducing. It is also an important opportunity to accumulate, summarize, and improve clinical rescue and treatment experience. Aiming at August 2nd Kunshan factory aluminum dust explosion, this article reviews and summarizes experience and problems about rescue reserve, first-aid system, multidisciplinary cooperation, and integration of usual time and emergent time treatment, so as to propose corresponding strategies and provide reference for the treatment of mass burn patients and critically burned patients.

Acute gastrointestinal dysfunction is a common and important complication of sepsis. As no exiting formal definition and classification of gastrointestinal dysfunction, most of the treatment strategies for gastrointestinal dysfunction are not based on clinical evidence, but on their own clinical experience. Experts of traditional Chinese medicine, integrated traditional Chinese and Western medicine and Western medicine from various disciplines in Shanghai are organized by the Shanghai Society of Integrated Traditional Chinese and Western Medicine and the Emergency Department Branch of Shanghai Physicians Association. After repeated discussion, literature search and formulation of the outline, we developed consensus on gastrointestinal dysfunction secondary to sepsis with integrating Traditional Chinese Medicine and Western medicine by consulting extensively on clinical experts in the fields of emergency medicine, gastroenterology, general surgery, infectious medicine and traditional Chinese medicine, and holding several expert forums and consultation meetings. This clinical expert consensus focused on acute gastrointestinal injury (AGI) classification and inducer of sepsis. In this consensus, the common symptoms, diagnosis, classifications, treatment strategies and suggestions of acute gastrointestinal injury or dysfunction secondary to sepsis were explored from the aspect of both Traditional Chinese Medicine and Western medicine.

OBJECTIVE: To investigate the association of phenylethanolamine-N-methyl transferase (PNMT) G-390A genetic polymorphism with risk of essential hypertension (EH) in Changsha Han people. METHODS: A case-control association study was performed in 400 patients with essential hypertension (EH) and 388 normotensive subjects. PNMT G-390A was genotyped using polymerase chain reaction-restriction fragment length polymorphism (PCR-FRLP). RESULTS: The genotype frequencies for the -390 GG, GA, and AA were 39.3%,50.0%, and 10.8%, respectively in EH patients, and were 43.6%,45.6%, and 10.8%, in normal subjects. No significant difference in either genotypic frequency (P=0.433) or allele frequency (P=0.378) of PNMT G-390A between EH patients and normals was observed. When by gender, there was significant difference in genotypic frequency (P<0.05) and allele frequency (P=0.046) of G-390A polymorphism between EH patients and normals in the male, but not in the female (P>0.05). CONCLUSION PNMT G-390A polymorphism is possibly associated with EH risk in male Chinese Han population in Changsha.
