Objective To evaluate the effect of fast track surgery on immunologic functions and clinical outcome in patients with gastric cancer during perioperative period. Methods Thirty-six gastric cancer patients receving radical operation were randomly divided into two groups: fast track group (18, fast track surgery) and conventional management group (18, non-fast track surgery). Serum levels of IgA、IgM、 IgG and C reaction protein (CRP) in 36 patients were assayed preoperatively and postoperatively on 1st, 3rd, 7th day. The postoperative hospital stay, duration of fever, inhospital expense, postoperative time of flatus and postoperative complications were recorded respectively. Results On the postoperative 3rd day, serum levels of IgA [(1.57 ± 0. 40) g/L vs. (1.27±0.49) g/L, P <0. 05],IgG[(9.99 ± 2. 12) g/L vs.(8.53±2. 15)g/L, P<0.05]and IgM [(0.92 ± 0.18) g/Lvs. (0.78 ± 0.20) g/L, P<0.05]in patients of fast track group were significantly higher than those in patients in non-fast track group. On the postoperative 1 st, 3rd , 7th day, serum levels of CRP [d1 (56 ± 10) g/L vs. (79 ± 9) g/L,P < 0. 05];d3[(140±15) g/L vs. (170±15) g/L, P<0.05)];d7 [(52±11) g/L vs. (78±12) g/L,P<0.05]in patients of fast track group were significantly lower than those in patients in non-fast track group. The duration of fever [(2. 4 ± 0.9) d vs. (3.8 ± 0. 8) d, P < 0.05], passage of gas by anus [(3. 1 ± 0. 8) d vs. (4.4±0.7) d,P<0.05], time of hospitai stay [(6.3 ± 1.2) d vs. (8.2 ± 0.9) d,P<0.05]and treatment expense in patients of fast track group[(25 260 ± 2910) $ vs. (30 651 ± 3578) $ ,P <0. 05]were also significantly lower than those in non-fast track group (P < 0. 05). Patients in fast track group had no more complications than those in non-fast track group (P > 0. 05). While discharged from hospital, the quality of life score [(14. 8 ± 1.9) vs. (16. 1 ± 1.6), P < 0. 05]in patients of fast track group was significantly higher than that in patients in non-fast track group (P < 0. 05). Conclusions Fast track surgery mitigates the immunologic impairment of gastric cancer patients during perioperative period, and accelerates postoperative rehabilitation.

BACKGROUND: Mesh plug tension-free hernioplasty is commonly used for inguinal hernia. In the operation, different mesh materials can be selected, among which the modified Kugel mesh is extensively applied. OBJECTIVE: To observe the biocompatibility of modified Kugel mesh in mesh plug tension-free hernioplasty for inguinal hernia. METHODS: Total y 79 cases of inguinal hernia were treated by mesh plug tension-free hernioplasty. The patients were randomly divided into observation group repaired with Bard mesh (modified Kuge) (n=38) and control group repaired with Prolene mesh (n=41). After 12-month fol ow-up, levels of interleukin 6, C-reactive protein and tumor necrosis factor α were detected and compared before and after treatment;adverse events, including wound infection or infection caused by the mesh in the two groups were recorded. RESULTS AND CONCLUSION: Levels of interleukin 6, C-reactive protein and tumor necrosis factor α in the two groups were significantly decreased after treatment than before treatment (P < 0.05). No wound infection or infection caused by the mesh appeared in both two groups. Although scrotum effusion occurred in two cases of each group, their outcomes al improved significantly after active puncture and suction treatment without other serious problems. No recurrence was found during the 12-month fol ow-up. These results show that the modified Kugel mesh has good biocompatibility in mesh plug tension-free hernioplasty for inguinal hernia.

OBJECTIVE:To optimize the drying technology of Zingiber officinale peel and establish its quality standard. METHODS:Moisture content was determined in samples after being dried for different time(0.5-10.0 h)under 50,60,70,80, 90 ℃. Optimal drying time under each temperature was screened by using moisture content of 7%-13% as dryness for controlling standard. Then contents of 6-gingerol,8-gingerol,6-shogaol,10-gingerol in samples dried for optimal drying time under different temperatures were measured,using the 4 gingerol contents as indexes to optimize the drying temperature and time. And verification test was conducted. The moisture,total ash,water soluble extract,volatile oil,6-gingerol,8-gingerol and 10-gingerol of Z. offici-nale peel from 10 different producing areas were detected to establish quality standard after being dried with the optimal technology. RESULTS:The drying time of Z. officinale peel under 50,60,70,80,90 ℃ was determined as 10.0,4.2,2.6,1.5,1.1 h,re-spectively. The optimal drying technology was 50 ℃ drying for 10.0 h. Verification test showed RSDs of 6-gingerol,8-gingerol, 6-shogaol,10-gingerol contents were 1.46%,1.09%,1.35%,1.12%(n=3),respectively. The quality standard of Z. officinale peel was suggested that total ash was no more than 18.0%;water soluble extract,volatile oil,6-gingerol,8-gingerol,10-gingerol were respectively no less than 18.0%,1.30%,0.730%,0.060%,0.100%. CONCLUSIONS:The optimized drying technology of Z. officinale peel is reasonable,reliable,stable and simple,which provides a scientific basis for standardizing the drying technolo-gy and quality standard of Z. officinale peel.
