This study was set up to observe the changes in stress and immune functions in upper abdominal surgery after general anesthesia.In thirty elective upper abdominal operation patients,general anesthesia was induced with propofol,fentanyl,scoline and maintained with isoflane and atrumium. Catecholamines(CA),cortisol,interleukin-2(IL-2) and soluble interleukin-2 receptor(sIL-2R) were measured before anesthesia,after induction of anesthesia,at the end of operation,and on the first and third postoperative days.The results showed that epinephrine(E),norepinephrine(NE) concentration increased at the end of operation and on the first postoperative day(P<0.01)，Cortisol concentration decreased after anesthesia induction(P<0.05)，IL-2 concentration decreased at the end of operation(P<0.05)，and sIL-2R lever did not change.The investigation suggested that general anesthesia with propofol,fentanyl and isoflane can suppress CA and cortisol increase resulting from induction of anesthesia. There was no change in IL-2 level.However it can not suppress the increase of stress hormones and decrease of IL-2 due to operation.The stress response correlate with immune functions.

Objective To observe the clinical contraeeption effects of GyneFix IN IUD,MCu IUD and TCu220C IUD.Methods From January 2005 to December 2006,comparative study was carried out by randomly applying 3 different types of IUDs(GyneFix IN,MCu and TCu220C IUD) for 300 healthy women.Follow-up survey was taken after 1,3,6,and 12 months.Results The pregnancy rates with IUD among 3 types of IUDs showed no significant difference(P>0.05).The expulsion rates of GyneFix IN IUD and MCu IUD were lower than that of TCu220C IUD(P<0.01).The removal rate of GyneFix IN IUD and MCu IUD were lower than that of TCu220C IUD(P<0.05).The 12 months cumulative continuation rates of GyneFix IN IUD and MCu IUD were higher than that of TCu220C IUD(P<0.01).Conclusions GyneFix IN IUD and MCu IUD can be recommended for clinical use based upon the advantages of lower pregnancy rate,lower removsl rate because of side-effect and higher cumulative continuation rate.Proper IUD should be selected depending on individuals,in order to increase the contraception effects and decrease the side-effects.

Objective To study the difference of Han male children and adolescent bone age of wrist-hand in Beijing and Guangzhou.Methods Bone age (BA) of left hand-wrist was assessed using X-ray by two radiologists based on CHN atlas method in 993 healthy children and adolescents (age range:1.0-19.0 years).The radiologists were blinded to the chronological age (CA) of those children.The interobserver variations were analyzed for evaluating the reliability of CHN Atlas method.The difference between CA and BA were separately assessed,and were analyzed by t test.Results Close correlation was found between BA and CA (r =0.969,0.957,P ＜ 0.01) in both two regions.The bone age was advanced at 1.0-3.9,and 7.0-15.9 years in Beijing boys,and at 1.0-2.9,6.0-7.9 years in Guangzhou bpys.There was significant difference at 1.0-1.9,9.0-14.9 years between Beijing and Guangzhou.Conclusions The bone age of Han male children adolescent in Beijing and Guangzhou area has the characteristic of acceleration.There is significance difference at some years between Beijing and Guangzhou,and the results can provide potential value for the further study of BA and clinical medicine.

Objective To evaluate the performance of the target controlled infusion(TCI) system with midazolam during combined spinal and epidural anesthesia. Methods Twenty female patients scheduled for selective lower abdominal or pelvic surgery under combined spinal and epidural anesthesia were enrolled in this study. They use combined spinal and epidural anesthesia with target controlled infusion of midazolam sedation. Midazolam plasma concentration was set at 100ng/ml. Blood pressure,heart rate, pulse oxygen saturation were monitored during anesthesia and operation. We use BIS as a pharmacodynamic value of midazolam sedation. Blood samples were taken from radial arterial for analysis of plasma midazolam concentration during infusion. Midazolam plasma concentration were tested by high performance liquid chromatography. Results MDPE of target controlled infusion with midazolam with Burher parameters was 38.7%, MDAPE was 38.7%,and wobble is 24.9% in Chinese female patients. Conclusions Burher parameters of midazolam target controlled infusion system should be correct, then can be used for our country female patients conscious sedation accurately.

OBJECTIVETo observe the effects between acupuncture combined with rehabilitation and simple rehabilitation for shoulder pain after stroke, and to select the best plan of acupuncture manipulations at different stages by orthogonal design.

METHODSNinety patients were treated with comprehensive rehabilitation, and nine cases without acupuncture were arranged into a control group. Eighty-one patients of orthogonal design were applied by acupuncture with the same acupoints and course. The VAS score and its weighted value were regarded as the observation indices,and the effects between the acupuncture group and the control group were compared. The optimal plans of acupuncture manipulations of the early stage and the later stage were chosen after the first course treatment and the third course treatment separately. The acupuncture depth (factor A:A: shallow depth less than 25 mm, A(II): modest depth 25-40 mm, A(III): deep depth 40-50 mm), the acupuncture angle (factor B:B(I): perpendicular insertion, B(II): horizontal insertion, B(III): oblique insertion), needle manipulated frequency (factor C: C(I): zero time, C(II): one time, C(III): three times) and needle retained time(factor D:D(I):20 min, D(II): 30 min, D(III): 60 min) were studied. The differences among all factors and the diversity among major factors at different stages were analyzed.

RESULTS(1) Acupuncture combined with rehabilitation at the early and the later stage acquired better improvement than simple rehabilitation (all P < 0.01). (2) The optimal acupuncture manipulation plan at the early stage was A(III) B(III) C(I) D(I), which was deep acupuncture and oblique insertion for 20 min with zero-time manipulation; the optimal acupuncture manipulation plan at the later stage was A(III) B(III) C(III) D(I), which was deep acupuncture and oblique insertion for 20 min with three-time manipulation. (3) There was significance for acupuncture depth and angle at the early stage (both P < 0.01) and there was significance for insertion depth, acupuncture angle and manipulating frequency at the later stage (all P < 0.05). (4) At the early stage, the insertion depth was statistically significant between A(I) and A(II), A(I) and A(III), A(II) and A(III) (P < 0.05, P < 0.01), and the statistical significance was existed between B(I) and B(III) (P < 0.01). At the later stage, the insertion depth was statistically significant between A(I) and A(III), A(III) and A(II), A(I) and A(II) (P < 0.05, P < 0.01), and the statistical significance was existed between C(I) and C(III), C(II) and C(III) (P < 0.05).

CONCLUSIONAcupuncture combined with rehabilitation acquire apparent effect for shoulder pain after stroke. At the early stage,the optimal plan is deep and oblique insertion for 20 min with zero-time manipulation. At the later stage, the best plan is deep and oblique insertion for 20 min with 3-time manipulation.
