Objective To explore dezocine preemptive analgesia in laparoscopic operation on serum interleukin-6(IL-6) and substance P.Methods 82 cases of laparoscopic operation were randomly divided into two groups,41 cases in the observation group,41 cases in the control group.Observation group was treated with routine anesthesia and analgesia with dezocine,the control group with routine anesthesia.Using visual analogue score (VAS) of pain scores,measured in the two groups of serum IL-6 and P material.Results The observation group after 2h,12h,24h VAS scores were (1.02 ±0.42),(2.19 ±0.87),(1.69 ±0.96) points,which were less than the control group (1.39 ±0.77)%,(3.08 ± 1.15)%,(2.27 ± 1.21)points (t =5.536 2,2.064 4,3.756 4,all P ＜0.05).The observation group before and after operation,serum IL-6,P material were (117.4 ± 17.2) mg/L,(204.4 ± 23.6) mg/L,(4.21 ± 0.96) mg/L,(4.33 ± 1.03) mg/L,the control group were (115.3 ± 14.7) mg/L,(276.5 ± 29.1) mg/L,(4.19 ± 0.94) mg/L,(6.92 ± 1.37) mg/L,two groups of postoperative serum IL-6,substance P (t =3.754 4,7.643 0,all P ＜ 0.05).Increased significantly,compared with the control group,the patients in the observation group the extent of small elevated(t =3.7544,7.6430,all P ＜ 0.05).Conclusion Dezocine extended analgesia in patients undergoing laparoscopic surgery can significantly reduce serum IL-6 and substance P expression.

Objective To investigate the relationship between inflammatory response and depth of propofol sedation during cardiac valve replacement with cardiopulmonary bypass (CPB).Methods Fifty patients undergoing cardiac valve replacement with CPB were randomly divided into low Bispectral index (BIS)group(30≤BIS<45)and high BIS group(45≤BIS≤60).Each group had 25 cases.The induction of anesthesia in the two groups was in the same way.Anesthesia was maintained in the fol‐lowing way :low BIS group and high BIS group received intravenous infusion of 7 mg/(kg · h) and 3 mg/(kg · h) propofol ,re‐spectively.In operation ,the propofol infusion rate was adjusted to maintain each group in the corresponding BIS value range.Before induction of anesthesia(T0 ) ,at the end of the CPB(T1 ) ,the end of operation(T2 )and 1 h after operation(T3 ) ,re‐spectively ,6 mL of jugular vein blood samples were collected.The concentrations of IL‐6 ,TNF‐αand S100βprotein in the serum were detected by ELISA method.At T0 ,T1 and T2 ,respectively ,arterial blood was collected ,the pH of blood and the concentra‐tions of blood glucose and lactate were determined.Results At T1 ,T2 and T3 ,the concentrations of IL‐6 and TNF‐αin serum in low BIS group were all lower than those in the high BIS group(all P<0.05).At T2 and T3 ,the S100βprotein concentrations in serum in the low BIS group were all lower than those in the high BIS group (both P< 0.05).Compared with the high BIS group ,the concentrations of blood glucose and lactate in low group at T 1 and T2 were all lower(all P<0.05).Conclusion Ap‐propriately enhancing the depth of sedation could help relieve the inflammatory reaction of patients during cardiac valve replace‐ment with CPB.It can help protect brain tissue and reduce the incidence of brain injury.

Objective To discuss the feasibility of minimally invasive drainage tube placement and tee-junctions irrigation for the treatment of chronic subdural hematoma. Methods Transcranial drainage and closed tee-junctions irrigation was carried out under local anesthesia in 31 cases of chronic subdural hematoma by using self-made trocar and osteotome. Results All the patients had been completely freed of the disease, without pneumocephalus. Follow-up for 3～6 months revealed no recurrence. Conclusions Minimally invasive tube placement and tee-junctions irrigation for chronic subdural hematoma is feasible. It not only clears away the lesions thoroughly, but also prevents the pneumocephalus effectively.

The expression of c-erbB-1 and c-erbB-2 oncoproteins were investigated by immunohistochemical technique using monoclonal antibodies to c-erbB-1 and c-erbB-2 oncoproteins in 43 cases of hasal cell carcinoma (BCC) and 26 cases of squamous cell carcinoma (SCC). The results showed that: ① The expression of c-erbB-1 oncoprotein in BCC increased; the expression of c-erbB-2 oncoprotein in BCC reduced significantly, and lost in 16 cases (16/43). ② The intensities of c-erbB-1 and c-erbB-2 oncoprorein expression had negative and positive correlations to the degrees of SCC differentiation respectively. It is suggested that the abnormal expression of c-erbB-1 and c-erbB-2 oncoprotein in BCC and SCC may play a role in the development of skin tumors.
