A study on the awareness of influenza and pneumonia and thewillingness of vaccination among chronic disease patients / 预防医学

Objective To provide evidence for effective implementation of influenza and pneumonia immune strategies, we investigated the awareness of influenza and pneumonia and the willingness of vaccination among chronic disease patients.Methods A stratified multistage cluster sampling method was used to investigate 720 patients less than 75 years of age.Results Overall, 717 completed responses were received.The awareness rates of influenza and pneumonia diseases were 59.83% and 59.55%, respectively.However, the awareness rates of influenza and pneumonia vaccine were 17.71% and 6.00%, respectively.The vaccination rate of influenza vaccine was 1.26% while no patients received pneumonia vaccination.Among those not vaccinated the most frequent reasons for not receiving the vaccine included "Believed oneself unlikely to be infected with influenza/pneumonia" and "No recommendation has been received for influenza/pneumonia vaccination".The influence on recommendations by doctors at vaccine clinic and by general practitioner had no significant statistical difference (P>0.05).Conclusion The main reasons for such low awareness and willingness may be due to their poorly knowledge on the risk of influenza/pneumonia diseases, and related vaccines.Health education and intervention should be taken to heighten the vaccination rates of influenza/pneumonia vaccines.

Study on synergism of bidirectional solid fermentation on antibacterial effect of Isatidis Radix and Isatidis Folium / 中草药

Objective: To explore the bidirectional solid fermentation transformation of 25 different edible fungal strains with Isatidis Radix (IR) and Isatidis Folium (IF) to get the synergism antibacterial effect of fermentation substance. Methods: The dominant strains grown on IR and IF were obtained through initial screening and repeated screening. The antibacterial effect of fermentation product substance were determined by antibacterial test and TLC. Results: The results showed that repeated screening got three strains which could grow fast in IR (G-11, G-13, and G-7) and IF (G-2, G-11, and G-3). The G-3 strain and G-11 strain fermentation substance had better antibacterial effect than IR and IF respectively. The methanol extract of G-2 fermented IF substance appeared a new spot by TCL, it should be an additional component after fermentation. Conclusion: The bidirectional solid fermentation could improved antibacterial effect of IR and IF, and the new active ingredients can be produced.

Expectant management of heterotopic cesarean scar pregnancy / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Heterotopic cesarean scar pregnancy (HCSP) is a very rare but life-threatening entity and there is no optimal management strategy. Here we report a successfully managed case of HCSP with expectant treatment in a tertiary referral hospital.</p><p><b>METHODS</b>A woman with HCSP after in vitro fertilization-embryo transfer opted for expectant treatment after five days of mild bleeding and ultrasound demonstrated cardiac activity disappearance of the scar pregnancy at 8(+4) weeks of gestation.</p><p><b>RESULTS</b>The patient had mild to moderate bleeding during close monitoring. Three days later, speculum examination revealed the gestational mass was partly protruding at the os of the cervix and it was removed with forceps without massive hemorrhage. A healthy male baby was delivered by cesarean section at gestational age of 36(+4) weeks.</p><p><b>CONCLUSIONS</b>The expectant method might be an alternative option for a HCSP with loss of cardiac activity of the scar pregnancy, when applied under supportive management and with available emergency surgery facilities.</p>

Research progress in outcome and safety of ICSI by different origin of sperm / 浙江大学学报·医学版

It's a very hot question whether different origin of sperms will affect the outcome and safety of ICSI. In this article,we reviewed the present researches on the outcome and safety of ICSI by different origin of sperms, including ejaculated sperms, testicular sperms,epididymal sperms and frozen-thawed sperms.

Clinical evaluation of wedge-shaped defect restored by gingival retraction technique / 中华口腔医学杂志

<p><b>OBJECTIVE</b>To evaluate the periodontal conditions after the wedge-shaped defect was restored by gingival retraction technique.</p><p><b>METHODS</b>A total of 138 mandibular premolars with wedge-shaped defect were selected and divided into A, B groups. Group A was restored with Dyract after using retraction cord. Group B was directly restored with Dyract. Clinical parameters including plaque index (PLI), gingival index (GI), sulcus bleeding index (SBI), probing depth (PD), volumes of gingival crevicular fluid (GCF) and levels of aspartate aminotransferases (AST) of gingival crevicular fluid were measured at baseline, 1 week, 1 month, 3 months and 6 months after operation.</p><p><b>RESULTS</b>There was no difference in PLI, GI, SBI, PD between group A and B during 6 months after operation, while the difference of GCF and AST was significant between group A and B at 3 months and 6 months after operation (P < 0.05, P < 0.01).</p><p><b>CONCLUSIONS</b>Gingival retraction technique applied in wedge-shaped defect restoration can reduce the damage to the periodontal tissue.</p>

In vitro maturation--n vitro fertilization--embryo transfer--frozen-thawed of human oocytes / 浙江大学学报·医学版

<p><b>OBJECTIVE</b>To investigate the influence of different cycles, ovarian follicle size and IVM culture media on the number of retrieved immature oocytes, maturation rate, fertilization rate, embryo quality and implantation rate, pregnancy rate, delivery rate, survival and development of frozen-thawed embryos from IVM.</p><p><b>METHODS</b>The oocytes were obtained by follicular aspiration from 19 women undergoing oocyte retrieval for in vitro maturation due to the possible risk of ovarian hyperstimulation in IVF-ET program. One patient was in natural cycle, four patients were in ovulation induction cycles with gonadotropine and fourteen patients is controlled ovarian stimulated cycles. All the oocytes retrieved from follicles with 10.0 - 13.5 mm in maximumdiameter were allowed to culture in medium M-199 (TCM 199) or HTF supplemented with other substance.</p><p><b>RESULT</b>When there were nonuniform diameters of follicles and the diameter of largest oocyte exceeded 12 mm, the retrieval rate of oocytes, fertilization rate, and the number of high-quality embryos decreased. The high-quality embryos formation rate was higher for the oocytes cultured in TCM 199 medium than in HTF medium (P<0.01). After being frozen-thawed, the IVM embryos could achieve the same outcome when compared with the conventional IVF treatment. In addition, the offspring were healthy.</p><p><b>CONCLUSION</b>When the nonuniform diameters of follicles and the diameter of largest oocyte exceeds 12 mm,the retrieval rate of oocytes, fertilization rate, and the number of high-quality embryos decreased. TCM199-based medium is better to improve the developmental potential and implantation rate of embryos derived from in vitro matured oocytes. After being frozen-thawed, the IVM embryos could achieve the same outcome when compared with the conventional IVF treatment. In addition, the offspring are healthy.</p>
