Objective To summarize the clinical experience of laparoscopic treatment of hepatic hydatid cysts. Methods The clinical data of 120 patients with hepatic hydatid cysts who received laparoscopic endocyst extraction were retrospectively analyzed .Results The procedure was successful in all cases with no intraoperative leakage of fluid from the hepatic hydatid cysts or occurrence of anaphylactic shock. Postoperatively, there were 4 cases of recurrence , 8 cases of biliary fistula, 8 cases of residual cavity hydrops, and 1 case of postoperative bleeding.All of the cases were cured.The mortality in our study was zero.Conclusions Laparoscopic extraction of endocyst of hepatic hydatid cysts is a safe and effective procedure.

Objective:To study the qualitative identification and quantitative analysis of Paeoniae radix Rubra in Fufang Fuqing lotion. Methods:TLC was used to identify Paeoniae radix Rubra. The content of paeoniflorinl was determined by HPLC. The mobile phase was acetonitrile-0. 01% phosphonic acid (13 ∶87), and the detection wavelength was 230 nm,the flow rate was 1. 0ml·min-1, the column temperature was 40℃,and the sample size was 10μl. Results:The results of TLC showed that the relevant spots were clear without any interference from the negative sample. The calibration curve of paeoniflorinl was linear within the range of 0. 070-4. 500 μg (r=1. 000 0). The average recovery was 98. 36% with RSD of 2. 73%(n=6). Conclusion:The methods are accurate and quick in the qualitative identification and quantitative assay of the preparation, which can be used for the quality control of Fufang Fuqing lo-tion.

Objective To establish the quality standard of Qingshen Granules. Methods Thin-layer chrmatography was used to identify Rheum officinale Baill., Hedyotis Diffusa Wild. and Coptis chinensis Franch.. The contents of rhein, emodin and chrysophanol were determined by HPLC. The HPLC consisted of Kromasil C18 (4.6 mm×250 mm, 5 μm), methanol-0.1% phosphonic acid (70∶30) as mobile phase, flow rate of 1.0 mL/min, detection wavelength at 245 nm, and the column temperature was 30 ℃. Results The results of TLC showed that relevant spots were clear without interference against the negative sample. The calibration curves for rhein, emodin and chrysophanol were found to be linear within the range of 0.003 3-0.42 μg (r =0.999 9), 0.008 0-0.51 μg (r=1.000 0), 0.009 9-0.32 μg (r=1.000 0), respectively. The average recoveries were 98.84%, 99.04% and 100.35% with RSD of 1.30% (n=6), 1.34% (n=6) and 1.89% (n=6), respectively. Conclusion The methods are accurate and quick in qualitative identification and quantitative assay, and can be used for the quality control of Qingshen Granules.

This study aims to save cost of sampling for estimating the area under the amlodipine plasma concentration versus time curve in 24 hours (AUC(0-24 h)). Limited sampling strategy (LSS) models was developed and validated by mutiple regression model within 4 or fewer amlodipine concentration values. Absolute prediction error (APE), root of mean square error (RMSE) and visual predict check were used as criterion. The results of Jackknife validation showed that fifteen (9.4%) of the 160 LSS based on regression analysis were not within an APE of 15% by using one concentration-time point. 156 (97.5%), 159 (99.4%) and 160 (100%) of the 160 LSS model were capable of predicting within an APE 15% by using 2, 3, 4 points, separately. Limited sampling strategies have been developed and validated for estimating AUC(0-24 h) of amlodipine. The present study indicated that the implemention of both 5 mg and 10 mg dosage could enable accurate predictions of AUC(0-24 h) by the same LSS model. This study shows that 12, 4, 24, 2 h after administration are key sampling time points. The combination of (12, 4), (12, 4, 24) or (12, 4, 24, 2 h) might be chosen as sampling hours for predicting AUC(0-24 h) in practical application according to requirement.

Objective:To investigate the clinical efficacy of anterior approach combined with blocking plates and screws in the management of acetabular fracture involving the quadrilateral area.Methods:A retrospective case series analysis was performed for 16 patients with acetabular fracture involving the quadrilateral area admitted to First and Second Affiliated Hospital of Guangxi Medical University from January 2017 to January 2019. There were 12 males and 4 females，with the age of 21-66 years［（45.3±10.6）years］. According to Letournel-Judet classification，there were 9 patients with bi-column fracture，6 with anterior and posterior traverse fracture and 1 with anterior column fracture. A total of 9 patients were operated via the ilioinguinal approach and 7 via the lateral-rectus approach. Reduction and fixation of the pelvis and acetabulum were performed，using 3.5 mm cortical bone screws or plates to block the internal displacement of fracture in the quadrilateral body. The incision length，operation time and intraoperative blood loss were recorded. The quality of fracture reduction was assessed according to the Matta reduction criteria at postoperative 2 days and hip function by the modified Merle D'Aubigne-Postel score at postoperative 3 months and 12 months. Postoperative complications were observed.Results:All patients were followed up for 13-24 months［（16.1±2.9）months］. The ilioinguinal approach and lateral-rectus approach showed surgical incision of 12-26 cm［（18.6±4.0）cm］and 8-15 cm［（10.7±2.3）cm］，respectively. The operation time was 107-215 minutes［（159.2±27.8）minutes］and the intraoperative blood loss was 200-2，300 ml［（853.1±489.7）ml］. According to Matta reduction criteria，the results were excellent in 9 patients and good in 7. Three months after operation，the modified Merle D'Aubigne-Postel score was 11-18 points［（15.2±2.2）points］，which showed the results were excellent in 4 patients，good in 7，fair in 4 and poor in 1，with the excellent and good rate of 69%. Twelve months after operation，the modified Merle D'Aubigne-Postel score was 13-18 points［（16.9±1.4）points］，which showed the results were excellent in 7 patients，good in 8 and fair in 1，with the excellent and good rate of 94%. The liquefaction of post-surgical incision was seen in a patient，bladder injury in a patient，lateral femoral cutaneous nerve injury in a patient，and heterotopic ossification in a patient. There was no loosening or breakage of the internal fixation.Conclusion:For acetabular fracture involving the quadrilateral area，anterior approach combined with blocking plates and screws can prevent the displacement of quadrilateral fracture and attain satisfactory reductiongood hip function recovery and few complications.
