KAT8/MOF-Mediated Anti-Cancer Mechanism of Gemcitabine in Human Bladder Cancer Cells

Histone acetylation is a well-characterized epigenetic modification controlled by histone acetyltransferases (HATs) and histone deacetylases (HDACs). Imbalanced histone acetylation has been observed in many primary cancers. Therefore, efforts have been made to find drugs or small molecules such as HDAC inhibitors that can revert acetylation levels to normal in cancer cells. We observed dose-dependent reduction in the endogenous and exogenous protein expression levels of KAT8 (also known as human MOF), a member of the MYST family of HATs, and its corresponding histone acetylation at H4K5, H4K8, and H4K16 in chemotherapy drug gemcitabine (GEM)-exposed T24 bladder cancer (BLCA) cells. Interestingly, the reduction in MOF and histone H4 acetylation was inversely proportional to GEM-induced γH2AX, an indicator of chemotherapy drug effectiveness. Furthermore, pGL4-MOF-Luc reporter activities were significantly inhibited by GEM, thereby suggesting that GEM utilizes an MOF-mediated anti-BLCA mechanism of action. In the CCK-8, wound healing assays and Transwell ® experiments, the additive effects on cell proliferation and migration were observed in the presence of exogenous MOF and GEM. In addition, the promoted cell sensitivity to GEM by exogenous MOF in BLCA cells was confirmed using an Annexin V-FITC/PI assay. Taken together, our results provide the theoretical basis for elucidating the anti-BLCA mechanism of GEM.

Research progress of tibial transverse transport for diabetic foot / 中国修复重建外科杂志

Objective: To summarize the research progress of tibial transverse transport in the treatment of diabetic foot. Methods: The domestic and foreign literature on the tibial transverse transport for diabetic foot in recent years was summarized, and the advantages and disadvantages of the technique were analyzed. Results: The tibial transverse transport was an innovation based on Ilizarov technique. At present, the treatment of diabetic foot by the tibial transverse transport is in the initial stage and has achieved good results, but there are also problems such as ulcer recurrence and re-fracture. And its biological mechanism to promote tissue regeneration, clinical technical points (such as the selection of incision and bone window size), the technical parameters of postoperative removal program, and the postoperative effectiveness are still in dispute and exploration. More clinical studies and practices are needed in the future to develop a standard protocol for this technique.

Clinical observation of the treatment of diabetic foot with transverse tibial bone transport / 西安交通大学学报(医学版)

Objective: To compare the clinical effects of transverse tibial bone transport, interventional therapy and conventional therapy on diabetic foot. Methods: We selected 45 diabetic foot patients admitted to the research center from June 2016 to October 2018. We adopted the random number method and divided them into the interventional treatment group, transverse tibial bone transport group and conventional treatment group, with 15 patients in each. Patients in each group received routine clinical treatment, interventional treatment or lateral tibial transposition. Doppler ultrasound was used to measure and monitor the blood flow velocity of dorsal artery before and after treatment. Each group was recorded for the highest systolic blood pressure of the malleolus artery and the highest systolic blood pressure of the brachial artery to measure the malleolus brachial index (ABI), the skin temperature and pain VAS scores of the affected limbs and feet before and after surgery. The healing of ulcerated foot surface was observed before and after operation to evaluate the clinical therapeutic effects of these methods. Results: All the 45 patients were followed up for an average of 6.7 months (4-10 months). Compared with those in conventional treatment group, the postoperative ABI and the blood flow velocity of the dorsal artery in interventional treatment group and transverse tibial bone transport group were significantly better(P0.05). Conclusion: Compared with conventional basic treatment, transverse tibial bone transport and interventional treatment can significantly improve the blood flow parameters of diabetic foot patients, relieve the pain of the patients and promote the healing of ulcer surface. Transverse tibial bone transport is more effective, and its postoperative skin temperature and postoperative brachial-ankle index are better than those of interventional treatment.

Upregulation of brain APJ receptor expression induced by high salt in pressure overload rats / 中国药理学通报

Aim To observe the effect of high salt stress on sympathetic nerve activity and brain Apelin and APJ system in pressure overload rats.Methods The suprarenal abdominal aorta was banded in male SD rats to create the pressure overload model.Four weeks later,the rats were fed a high-salt (8%NaCl)diet or a regular-salt (0.3% NaCl)diet for 1 week,and the hemodynamic changes of the rats were recorded.Sym-pathetic activity was evaluated by measuring 24 h uri-nary norepinephrine (NE)by ELISA.Real-time RCR and Western blot method were used to analyze the Ape-lin and APJ expression in the paraventricular nucleus of rats.In another protocol,ML22 1 or benzamil was intracerebroventricularly infused in the aorta banding rats fed with high-salt,and levels of 24 h urinary NE and cardiac index were recorded.In addition,normal SD rats were intracerebroventricularly infused with Na+-rich aCSF for 1 week,and the changes of blood pressure,24 h urine-NE and APJ expression levels were detected.Results In the pressure overload rats fed with high salt diet for 1 week,the mean arterial blood pressure (MAP),heart rate (HR),left ventric-ular end systolic pressure (LVESP),24 h urinary NE and APJ mRNA protein expression in paraventricular nuclear were significantly increased compared with those in control groups (P<0.05 ).However,the he-modynamics,24 h urinary NE and APJ expression showed no significant change in the sham rats fed a high salt diet.In addition,ICV infusion of APJ recep-tor antagonist ML221 or the ENaC antagonist benzamil significantly inhibited the 24 h urinary NE level and HW/BW ratio in the pressure overload rats fed high salt diet (P <0.01 ).Intracerebroventricular infusion of high Na+aCSF for 1 week in normotensive rats also significantly increased the MAP,HR,urinary-NE lev-els and brain APJ expression (P <0.0 1 ).Conclu-sions High salt increases the sympathetic nerve activ-ity in rats with pressure overload model, which is closely related to the brain APJ receptor expression and Na+sensitivity.Brain APJ receptor may be an impor-tant target in the development of salt sensitivity.

Type AO-C1 thoracolumbar vertebral fracture-dislocations：four-screw two-rod single-segment reduction fixation / 中国组织工程研究

BACKGROUND:The type AO-C1 thoracolumbar acute spine injury is a kind of high-energy instable injury, can cause thoracolumbar fracture-dislocation, and mainly associated with spinal nerve injury. Generaly, al needs to posterior open reduction, decompression, bone graft fusion and multiple-segmental internal fixation of pedicle screw rod system, which causes excessive loss of spinal movement segment and a large number of application of internal fixators. OBJECTIVE:To evaluate the treatment effect of posterior pedicle screw mono-segmental internal fixation for treatment of the type AO-C1 thoracolumbar vertebrae fracture-dislocations. METHODS:From January 2008 to December 2013, 17 cases of type AO-C1 thoracolumbar fracture-dislocation were folowed up. Al patients were treated with one-stage posterior open reduction and pedicle screw-rod fixation. Of them, eight cases received four screws and two rods for single-segment fixation in upper and lower vertebrae adjacent to intervertebral space after dislocation (4-screw 2-rod group). Nine cases received eight screws and two rods for multiple-segment fixation in the upper and lower vertebrae adjacent to intervertebral space after dislocation (8-screw 2-rod group). Operative time and intraoperative blood loss were compared between the two groups. The Cobb’s angle was measured on lateral X-ray film of two groups preoperatively and 1 week postoperatively and during the final folow-up. The neurological function was evaluated by Frankel classification. The visual analogue scale was adopted to assess the degree of low back pain. RESULTS AND CONCLUSION:Patients were folowed up for 1 to 5 years. Significant differences were detected in the operative time between the two groups, and operative time was better in the 4-screw 2-rod group than in the 8-screw 2-rod group (P < 0.05). No significant difference was found in intraoperative blood loss between the two groups. The deformity of fracture-dislocation had been corrected, and the pain of low back had significantly relieved in al patients after fixation. According to Frankel classification, two cases at Grade A were improved to Grade E, but eight cases at Grade A got no improvement after treatment. Two cases at Grade B were also improved to Grade E at the final folow-up. Significant differences in Cobb’s angle and visual analogue scale were detectable at 1 week postoperatively and during final folow-up as compared with preoperatively (P < 0.05), but no significant difference was visible between final folow-up and 1 week postoperatively. No significant difference in Cobb’s angle and visual analogue scale was observed between the 4-screw 2-rod group and 8-screw 2-rod group. Results indicate that there was no significant difference in the clinical efficacy between 4-screw 2-rod single-segment and 8-screw 2-rod multiple-segment fixation for treating type C1 thoracolumbar vertebrae fracture-dislocation. Therefore, AO-C1 thoracolumbar vertebrae fracture-dislocation could be treated with 4-screw 2-rod single-segment reduction fixation.

Methods From 1998 to 2007, 8507 neonates from 6551 pregnancies conceived through assistant reproductive technology (ART) from 7 reproductive medicine center in Shanghai were enrolled in this retrospective study, including Shanghai Ji-Ai Genetics and IVF Institute, Shanghai Jiaotong University School of Medicine affiliated Renji Hospital,Buijin Hospital, China Welfare Institute International Maternal and Infant Health Hospital, Shanghai First Maternity and Infant Health Hospital, Shanghai the Ninth People's Hospital and the Second Military Medical University affiliated Changhal Hospital. The clinical data about the type and incidence of birth defect were analyzed. Meanwhile, the factors associated with birth defect were investigated, such as various ART,gender, mother age, numbers of gestational sac, the source and quality of sperm. Results The birth defect rate was 1.08% (92/8507) and the most remarkable malformation occurred in circulation system [34% (31/92)]. The rates of major congenital malformations were 1.21% (34/2799) in fresh conventional IVF-ET, 1.07% (20/1871) in IVF-frozen-thawed embryo transfer(IVF-FET), 1.04% (23/2212) in fresh intracyto plasmic sperm injection (ICSI)-ET and 0.92% (15/1625) in ICSI-FET, which did not show statistical difference (P>0.05). There was also no significantly different incidence of malformations between 1.12% (49/4371) in male neonates and 1.02% (42/4136) in female neonates (P >0.05).However, the occurrence of congenital malformation is positively related with maternal age, the rates were 0.84% (41/4884) in mother's age less than 30 years and 1.77% (16/902) in mother' age more than 35 years, which reached statistical difference (P < 0.05). It also showed remarkable different incidence among 0.53% (25/4679) in singletons, 1.59% (57/3576) in twins and 3.97% (10/252) in triplets (P< 0.05). No remarkable difference of malformation rate among sperm sources used in fertilization were observed, including 1.09% (81/7419)in ejaculated sperm, 1.21% (7/579)in percutaneous epididymal aspiration (PESA) and 0. 79% (4/509) in donor sperm (P>0.05). Conclusions The overall incidence of birth defect in neonates from ART is similar to those conceived naturally and is not associated with different types of IVF-ET, embryo cryopreservation, sperm sources. However, maternal age and multiple pregnancies coder the higher possibility of birth defect.

Investigation of the situation of vaginal microflora in healthy women population / 中华妇产科杂志

Objective To assess the distribution of vaginal microflora in healthy women and investigate their cognition of lower reproductive tract infection-related knowledge as well as personal hygiene habits and character of behavior in seeking medical treatment. Methods Total of 1660 healthy women who had physical check-ups at the Medical Center of Renji Hospital were selected and received gynecologic examination, as well as routine examination, pH examination and bacterial culture of the vaginal discharge. In addition, 860 of them were randomly selected for questionnaire survey, in which reproductive tract infection -related knowledge and personal hygiene habits as well as behavior in seeking medical treatment were involved. Results Among the 1660 eensused women, vaginal average pH was 4. 16±0.21. The positive rate of Candida in vaginal discharge routine examination was 3.86% (64/1660), which was lower than that in aerobes culture 7.71% (128/1660). Candida alhicans was the most populous species 78.9% (101/128) ,followed by 7.8% (10/128) and 7.0% (9/128) for the Candida glabrata and Candida krusei respectively. The most populous species of vaginal microflora were hemolytic streptococcus A (63.80%, 1059/1660), Staphylococcus epidermidis (14.28%, 237/1660), and Enterococcus faecalis (D) group ( 11.44%, 190/1660). The questionnaire survey showed that 88.4% (760/860) of 860 women took active treatment when feeling unwell, 92.1% (792/860) of them had good hygiene practices, and only 21.2% (182/860) had the habit of vaginal douching. In addition, 50.0% (430/860) of them had the desire to obtain reproductive health knowledge through out-patient consultation. Conclusions Vulvovaginal Candida disease ranks the first in all types of vaginitis, among which, Candida albicans is the most populous species followed by the Candida glabrata and Candida krusei. Hemolytic streptococcus A and Staphylococcus epidermidis are the most common species of vaginal mieroflora in healthy women. The censused women have high awareness of reproductive health care and pay mueh attention to common gynecologic diseases such as lower reproductive tract infection. Nevertheless, we should strengthen the public education of reproductive health-related knowledge.
