AIM: To explore the effect of insulin on the proliferation and expression of transforming growth factor ? 1 (TGF ? 1) and its receptors in aortic vascular smooth muscle cells (VSMC) from spontaneously hypertensive rats (SHR) and from the normotensive Wistar-Kyoto(WKY) rats. METHODS: VSMCs from aortas of WKY rats and SHR were prepared by an explant method. The effect of insulin on VSMC proliferation were measured by cell counting and flow cytometry analysis, respectively. Quantitative reverse transcription polymerase chain reaction (RT-PCR) technique was used to probe TGF ? 1 and its receptor mRNA on VSMC. RESULTS: Insulin enhanced the proliferation of VSMC from SHR in a dose-dependent manner ( P 0 05). CONCLUSIONS: The responses to insulin of TGF ? 1 and its receptor in SHR and WKY are significantly different. This abnormal regulation by insulin may be associated with an exaggerated proliferative response in SHR derived cells.

Objective To evaluate the efficacy of continuous incision analgesia with 0.2％ levobupivacaine for postoperative analgesia in parturients undergoing cesarean section.Methods Thirty ASA physical status Ⅰ or Ⅱ parturients who were at full term,aged 20-30 yr,weighing 60-80 kg,undergoing elective cesarean section,were enrolled in the study.The parturients received 0.2％ levobupivacaine 2 ml/h via a continuous incision analgesia device at the end of surgery.Pain was evaluated by visual analogue scale (VAS).Additional tramadol 50 mg was given when VAS score was above 3 and the consumption was recorded.The effective analgesia within 48 h after surgery (no addition of tramadol,VAS score ≤3) was recorded.The serum prolactin level was measured at 30 min before cesarean section and 24 and 48 h after cesarean section.The colostrum time was recorded.The toxic reaction and side effects were recorded.Results The effective analgesia rate was 80 ％.The consumption of tramadol was (95 ± 15) mg.The colostrum time was (24 ± 6) h.No toxic reaction was found.The serum prolactin level was significantly higher at 24 and 48 h after surgery than that at 30 min before surgery (P ＜ 0.05).Conclusion Continuous incision analgesia with 0.2％ levobupivacaine provides better efficacy,earlier colostrum time and fewer side effects for postoperative analgesia in parturients undergoing cesarean section.

OBJECTIVE:To study the general pattern and characteristics of the ADRs associated with Houttuynia cordata injection(HCI).METHODS:An analysis was conducted on55cases of ADRs induced by HCI reported in domestic medical jou_ rnals in recent years.RESULTS:The ADRs of HCI were not related to the dosage given.The onset of ADRs was commonly within30min during infusion.The ADRs mostly occurred in groups of patients under age20and from30to59years of age.The ADRs could involve multiple organs and systems,and the clinical manifestations were varying,of which allergic reaction was the commonest one including anaphylactic shock.CONCLUSION:The mechanism of allergic reaction induced by HCI remains to be further studied.Clinical physicians,nurses and pharmacists should pay more attention to the ADRs of HCI.

Objective To investigate the effects of 4 °C hypertonic saline (HTS) on S100 protein in serum and brain tissues of rats after cardiac arrest (SCA). Method Thirty SD male rats were randomly divided into shame-operated group (A), NS group (B) ,4℃ NS group (C), HTS group (D) and 4℃. HTS group (E), in e-qual number ( n = 6). Drugs were given to the rats of all groups at the initiation of CPR except group A. The rat model of CA was induced by asphyxia. Over 24 hours after restoration of spontanous circulation ( ROSC), venous blood sample was drawn to detcect the concentration of serum S100 protein in each group, and the rats were sacrificed and their brain tissues were taken for comparing the expressions of S100 protein in hippocampus. One-way analysis of variance and q -test were used for comparison among groups. P < 0.05 was considered significant. Results Compared with group A, the concentration of serum S100 protein in other groups were much higher ( P < 0.01). Compared with group B,the concentrations of serum S100 protein in groups C, D and E were also much lower ( P < 0.01). Compared with groups D and E, the concentration of serum S100 protein in group C was much higher ( P < 0.01). Compared with group D, the concentration of serum S100 protein in group D was higher ( P < 0.05). Compared with group A, the expressions of S100 protein in rats brain tissues of groups B,C and D were much higher ( P < 0.01). The expression of S100 protein in brain tissue of rats in group E was also higher than that in rats of group A ( P < 0.05). Compared with group B, the expressions of S100 protein in brain tissues of rats in groups C,D and E were lower (P < 0.05 and P < 0.01). Compared with group C, the expressions of S100 protein in brain tissues of rats in groups D and E were lower (P < 0.01). Compared with group D, the expression of S100 protein in brain tissue of rats in group E was lower (P < 0.05). Conclusions After CA the 4℃ HTS can decrease serum S100 protein level and inhibit the expression of S100 protein in hippocampus, then protecting the brain tissue.

Objective To compare the effects of allogeneic blood transfusion and hemodiluted autotransfusion on cellular immune function in the patients undergoing cesarean section.Methods Sixty patients,aged 20-35 yr,weighing 50-80 kg,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,scheduled for elective cesarean section,were randomly divided into 2 groups (n =30 each) using a random number table:hemodiluted autotransfusion group (group HAT) and allogeneic blood transfusion group (group ABT).Both groups received epidural anesthesia.The radial artery was cannulated after epidural anesthesia,and the autologous blood was collected in group HAT.The autologous blood transfusion timing:intraoperative blood loss was expected to exceed 20％ of blood volume.For the patients in whom intraoperative blood loss was not expected to exceed 20％ of blood volume,bleeding was stopped,and autologous blood was infused intravenously after peritoneum closure.The allogeneic blood transfusion timing:when hemoglobin ＜ 70 g/L,packed red blood cells 1-5 U were infused intravenously;when prothrombin time,or activated partial thromboplastin time ＞ 1.5 times of the normal value,the fresh frozen plasma 100-400 ml was infused intravenously;when platelet count＜50× 109/L,platelets 10-40 U were infused intravenously.When entering the operating room (T0),on 1st day after operation (T1),and on 5th day after operation (T2),blood samples were collected to detect the levels of T lymphocyte subsets CD3+,CD4+ and CD8+ (using FACScan flow cytometer),and serum interleukin-2 (IL-2) and IL-6 concentrations (by enzyme-linked immunosorbent assay).CD4+/CD8+ ratio was calculated.Results Compared with the values at T0,the levels of CD3+ and CD4+,CD4+/CD8+ ratio,and serum IL-2 concentrations were significantly decreased,and the serum IL-6 concentrations were increased at T1,2 in group ABT,and at T1 in group HAT (P＜0.05).Compared with group ABT,the CD3+ and CD4+ levels,CD4+/CD8+ ratio and serum IL-6 concentrations were significantly increased at T1,and the serum IL-2 concentrations were increased at T1,2 in group HAT (P＜0.05).Conclusion Compared with allogeneic transfusion,hemodiluted autotransfusion has less inhibitory effect on cellular immune function in the patients undergoing cesarean section.

To explore a new strategy for further optimization to the C-3 bioisteric heterocyclic ring of fluoroquinolones,twelve novel fluoroquinolone C-3 s-triazole Schiff-base carboxylic acid derivatives(7a-71) were designed and synthesized with both functionalized sulfanylacetic acid and Schiff-base moieties as the modified side-chain for the C-3 bioisosteric s-triazole ring of pefloxacin(1).The structures were characterized by elemental analysis and spectral data,and the in vitro anti-tumor activity of the title compounds against SMMC-7721,L1210 and HL60 cell lines was evaluated.The preliminary pharmacological results demonstrated that the title compounds possessed more significantly anti-proliferative activity than either the parent 1 or the corresponding amine intermediates(6).In particular,the title compound bearing a fluorine atom (7j) and compound bearing a nitro group attached to benzene ring (71) were comparable to the control doxorubicin against SMMC-7721 cells with an IC50 value of micro-molar concentration,respectively.It suggests that s-triazole ring modified with functional side-chain moieties instead of the C-3 carboxylic group is favorable to the improvement of antitumor activity.
