Objective To investigate the effects of penehyclidine hydrochloride (PHCD)on cerebral ischemia-reperfusion injury induced by intrauterine distress in fetal rats.Methods Eighty mature fetal rats weighing 4.52-4.81 g were randomly divided into four groups (n =20):sham opera-tion group(group S),PHCD control group (group S+ P),cerebral IR group (group IR),PHCD treatment group(group IR+P).Fetal rat intrauterine distress model was set up by clamping bilateral uterine horn vessels of pregnant rats.PHCD 2 mg/kg was injected in pregnant rat’s gluteus at 30 min before intrauterine distress model was set up in group IR+P,the same volume saline was injected in pregnant rat’s gluteus before shame operation in group S,the same volume PHCD was injected in pregnant rat’s gluteus before shame operation in group S+P.Fetal rats were decapitated at 12 h after the reperfusion,the peripheral blood of fetal rats was detected by blood gas analysis (including PH, PaO 2 ,PaCO 2 ,Lac);the infarct volume and the infarct volume fraction were detected by TTC stai-ning;pathological changes in lung tissue were observed by HE staining;the TNF-α,IL-6 content in the brain were detected by ELISA;the expression of NF-κB mRNA was detected by quantitative Real-time PCR,the expression of NF-κB p65 protein was detected by Western-blotting.Results The blood PH,PaO 2 in group IR and IR+P were lower than group S and S+P,the blood PH,PaO 2 in group IR+P was higher than group IR.Compared with group S and group S+P,the blood PaCO 2 , Lac,the infarct volume and the infarct volume fraction,the concentration of TNF-αand IL-6,the ex-pression of NF-κB mRNA and protein were significantly increased in group IR and IR+P (P <0.05), and those in group IR+P were lower than group IR (P <0.05 ).The pathological changes in brain tissue were significantly attenuated in group IR + P (P < 0.05 ).Conclusion Pretreatment with PHCDcouldattenuatecerebralischemia-reperfusioninjuryoffetalratsinducedbyintrauterinedistress.

Objective To perform modification study of cyanoacrylate (CA) medical adhesive and to select the optimal mo-difying material and the best ratio.Methods Carboxylic multi-walled carbon nanotubes (MWCNTs-COOH), multi-walled carbon nanotubes (MWCNTs), hydrophobic nano-silica, nitrile rubber, epoxy resin and polymethyl methacrylate (PMMA) were used to modify 5% triclosan/cyanoacrylate antimicrobial adhesive respectively. The bond strength, toughness and viscosity of the modified adhesive were examined in different concentrations.Results 0.064% MWCNTs-COOH, 6% nano-silica, 4% nitrile rubber and 6.4% epoxy resin all had good effects in strength modification. The bond strength were (14.71±1.48)MPa, (14.03±1.92)MPa, (14.6±1.78)MPa and (14.05±1.46)MPa respectively. 8% nano-silica had the lowest Tg of (1.1±0.24)℃ and the strongest viscosity of (15 536.68±28.4)cP. When the nano-silica concentration was 8%, the compound was very viscous and sticky. When the antimicrobial adhesive modified with 6% nano-silica, the bond strength was (14.03±1.92)MPa, the Tg was (3.6±0.68)℃, and the viscosity was (5 278.87±31.68)cP.Conclusion 6% nano-silica is the best modifying material, and has the optimal effect of modification.

Objective:To investigate the short-term effect of Cinobufacin injection combined with chemotherapy on elderly patients with colorectal cancer and its influence on tumor markers and immune function.Methods:Sixty-two elderly patients with colorectal cancer admitted to Xinchang Branch of Zhejiang Hospital of Traditional Chinese Medicine from January 2015 to December 2017 were randomly divided into observation group (31 cases) and control group (31 cases). Patients in the control group were treated with chemotherapy, while those in the observation group were treated with Cinobufacin injection on the basis of the control group. Two treatment of 21 d was as a cycle, continuous chemotherapy 2-4 cycles. The short-term therapeutic effect, Karnofsky function state score (KPS score), serum tumor markers, immune function and side effects of the two groups were compared before and after treatment.Results:After treatment, the total effective rate of the observation group was 77.42%(24/31), and was higher than that of the control group 48.39%(15/31), there was significant difference ( χ2=5.599, P<0.05). The KPS scores of the observation group was higher than that of the control group [(87.48 ± 6.57) scores vs. (80.20 ± 6.12) scores], there was significant difference ( t=4.514, P<0.05). The levels of serum cancer antigen 19-9(CA19-9), carbohydrate antigen 724(CA724) and carcino-embryonic antigen (CEA) in the observation group were lower than those in the control group [(3.59 ± 1.02) kU/L vs. (6.98 ± 1.37) kU/L, (7.38 ± 1.87) μg/L vs.(9.82 ± 1.42) μg/L, (12.27 ± 2.36) μg/L vs.(16.57 ± 3.24) μg/L], there were significant differences ( t=11.051, 9.042, 10.624, P<0.05). The levels of CD 3+, CD 4+ and CD 4+/CD 8+ in the observation group were higher than those in the control group [(58.97 ± 3.72)% vs. (47.31 ± 2.98)%, (38.85 ± 3.25)% vs. (30.19 ± 2.71)%, 1.59 ± 0.18 vs. 0.89 ± 0.14], there were significant differences ( t=13.620, 11.394, 17.091, P<0.05). The incidence of side effects in the observation group was lower than that in the control group ( P<0.05). Conclusions:Cinobufacin injection combined with chemotherapy can improve the quality of life of elderly patients with colorectal cancer in the near future, reduce the levels of serum CA19-9, CA724 and CEA, improve the immune function of patients, and have fewer side effects.

Objective To compare the clinical efficacy between Clamshell incision and bilateral posterolateral incision in the sequential double lung transplantation for end-stage lung disease. Methods Clinical data of 120 recipients undergoing double lung transplantation were retrospectively analyzed. All recipients were divided into bilateral posterolateral incision group (n=108) and Clamshell incision group (n=12) according to different surgical methods. Intraoperative parameters were collected and statistically compared between two groups, including operation time, amount of blood loss, amount of blood transfusion, use of extracorporeal membrane oxygenation (ECMO) or not, cold ischemia time on the first side, and cold ischemia time on the second side. Postoperative parameters were also compared between two groups, including the length of hospital stay, length of intensive care unit (ICU) stay, tracheal intubation duration, ECMO duration, forced vital capacity (FVC), forced expiratory volume in one second (FEV1), incidence of anastomotic stenosis, incidence of bronchopleural fistula, perioperative fatality, and 6-minute walk test for the first time after operation. Results In the Clamshell incision group, the amount of blood loss and blood transfusion was significantly higher than those in the bilateral posterolateral incision group (both P < 0.05). The proportion of ECMO and cold ischemia time on the second side in the Clamshell incision group were significantly lower or shorter than those in the bilateral posterolateral incision group (both P < 0.05). In the Clamshell incision group, the tracheal intubation duration and ECMO duration were significantly shorter compared with those in bilateral posterolateral incision group (both P < 0.05). Conclusions Both Clamshell incision and bilateral posterolateral incision are safe and effective in sequential double lung transplantation. Bilateral posterolateral incision approach can significantly reduce the amount of blood loss and blood transfusion of the recipients without significantly prolonging the operation time. Compared with bilateral posterolateral incision approach, the cold ischemia time of lung graft, tracheal intubation duration and ECMO duration are significantly shortened via the Clamshell incision.
