Objective:To evaluate the effect of robot-assisted laparoscopic technology via abdominal approach for patients with primary retroperitoneal tumors.Methods:A retrospective cohort analysis was conducted for the clinical data of 71 patients who underwent robot-assisted laparoscopic resection of primary retroperitoneal tumor via abdominal approach at the Department of Urology of Sir Run Run Shaw Hospital,Zhejiang University School of Medicine from January 2015 to December 2023. There were 35 male and 36 female patients. The age ( M(IQR)) was 56(21) years (range: 21 to 83 years). The median tumor diameter was 46 (31) mm (range: 15 to 134 mm). Postoperative pathology revealed 58 benign and 13 malignant cases. Patients were divided into non-adherent group ( n=47) and adherent group ( n=24) based on whether the tumor was adhered to major organs or vessels. Perioperative and postoperative situation were compared between the two groups. Data comparisons were conducted using independent samples t-test for normally distributed continuous variables, Mann-Whitney U tests for non-normally distributed data, χ2 test or Fisher′s exact test for categorical variables. Kaplan-Meier survival analysis was employed to estimate 3-year recurrence or metastasis rate and 3-year mortality rate. Results:Operative time was 120(60) minutes (range: 45 to 440 minutes), intraoperative blood loss was 50 (80) ml (range: 10 to 2 000 ml). The median change of intraoperative mean arterial pressure was 40 (19) mmHg(1 mmHg=0.133 kPa)(range: 10 to 112 mmHg). Intraoperative blood transfusion was required in 7 cases, whereas 64 cases did not necessitate transfusion. The change in hemoglobin levels before and after surgery was (17.9±13.6) g/L (range:-16 to 53 g/L), and the median change in serum creatinine levels was 2.0 (14.5) μmol/L (range:-71.0 to 100.4 μmol/L). Postoperative fasting duration was 2.0 (1.5) days (range: 1 to 6 days), and the median hospital stay was 10.0 (7.5) days (range: 4 to 24 days). No perioperative mortality occurred in any of the patients. The non-adherent group had shorter operation time, less estimated blood loss, lower blood transfusion rate, smaller delta value of hemoglobin before and after surgery, larger delta value of creatinine before and after surgery, fewer postoperative complications, shorter postoperative fasting time, and shorter length of hospital stay than the adherent group(all P<0.05), while there was no significant difference in mean arterial pressure fluctuation between the two groups ( P>0.05). Follow-up data were available for 69 patients, with a median follow-up duration of 39 (43) months (range: 4 to 88 months). Among these patients, 40 completed the 3-year follow-up. The 3-year recurrence or metastasis rate was 10.14%, and the 3-year mortality rate was 2.90%. Conclusions:Robot-assisted laparoscopic technology via abdominal approach for resection of primary retroperitoneal tumors is safe and feasible. It can also achieve secure surgical outcome for primary retroperitoneal tumors adherent to surrounding organs or vessels, albeit with increased surgical complexity and slower postoperative recovery compared to non-adherent cases.

Objective To compare the efficacies of several commonly-used penetrating needling methods in treating post-stroke strephenopodia. Method Eighty-three patients with post-stroke strephenopodia were randomized into four groups, a control group intervened by conventional needling method (n=20), and the rest three groups were additionally intervened by different penetrating needling methods: penetrating group 1 [Qiuxu (GB40) towards Zhaohai (KI6), n=21], penetrating group 2 [Taibai (SP3) towards Shugu (BL65), n=21], and penetrating group 3 [Jiaoxin (KI8) towards Fuyang (BL59), n=21], to compare their effects on the function of ankle and lower extremity. Result The penetrating needling methods and conventional needling method all can significantly improve the function of ankle in patients with post-stroke strephenopodia (P<0.01). The effectiveness of penetrating group 1 was more significant than that of the rest groups (P<0.01), the effectiveness of penetrating group 2 was more significant than that of penetrating group 3 and the control group (P<0.05,P<0.01), and there was no significant difference in comparing the effectiveness between penetrating group 3 and the control group (P > 0.05). The penetrating needling methods and conventional needling method all can significantly improve the motor function of lower extremity in patients with post-stroke strephenopodia (P<0.01). The effectiveness of penetrating group 1 was more significant than that of the other groups (P<0.01), the efficacies of penetrating group 2 and 3 were more significant than that of the control (P<0.01), and there was no significant difference in comparing the effectiveness between penetrating group 2 and 3 (P>0.05). Conclusion Needling from Qiuxu towards Zhaohai and from Taibai towards Shugu can produce significant effects in improving ankle function and the motor function of lower extremity in patients with post-stroke strephenopodia, while needling from Jiaoxin to Fuyang doesn’t have notable advantage compared to the other penetrating needling methods and conventional needling method.

OBJECTIVETo prepare puerarin deoxycholate/phospholipid mixed micelle to increase the solubility of puerarin.
METHODSodium deoxycholate and soybean phospholipids were used to prepare puerarin mixed micelle through orthogonal design experiments. With the solubility, shape and particle size as the response indexes, the preparing process of puerarin mixed micelle was optimized.
RESULTThe optimized process for the puerarin deoxycholate/phospholipid mixed micelle was that the puerarin, soya phosphatidylcholine and sodium deoxycholate with the mole ratio of 3:2:4 should be dissolved in methanol-chloroform (1:1), and the solvents should be evaporated rotatively at 30 degrees C. The particle diameter of the mixed micelle was (64.8 +/- 13) nm (volume-weighted particle size distribution), and the solubility was 0.811 1 g x L(-1) in water at the room temperature, which was 22.3 times as that of the raw puerarin (0.036 4 g x L-1).
CONCLUSIONThe puerarin deoxycholate/phospholipid mixed micelle can improve the solubility of puerarin significantly.
