Objective To develop a method for rapid determination of the dissolution of cefixime capsules,to explore the consistency of the dissolution curves of the generic and reference preparations in different media,and to assess the reliability of the in vitro dissolution evaluation method according to the results of bioequivalence studies.Methods The dissolution test was performed by the paddle method at 50 r·min-1,using pH1.2 hydrochloric acid solution,pH6.8 phosphate buffer solution,pH7.5 phosphate buffer solution,and water as the dissolution media.And a high-performance liquid chromatography(HPLC)method with a core-shell column was established to determine the dissolution curves of the generic and reference preparations respectively.The bioequivalence of the generic and reference preparations was evaluated through the bioequivalence(BE)test.Results The similarity factors(f2)of the three batches of the generic and reference preparations in the four media were greater than 60.The fasting and postprandial pharmacokinetic parameters(Cmax,AUC0-t,AUC0-∞)of the generic and reference preparations in hu-mans were all in line with the bioequivalence standard.Conclusion The in vitro dissolution behavior of the generic and refer-ence preparations was consistent,and the two preparations were bioequivalent.The method is simple and quick,and it can be em-ployed to measure the dissolution of cefixime capsules,which can provide references for the consistency evaluation of cefixime capsules.

Objective:To evaluate whether additional radical surgery is necessary following non-curative endoscopic resection of early colorectal cancer.Method:Clinicopathological data in 104 patients following non-curative endoscopic resection of early colorectal coucer at the Department of General Surgery, Peking University First Hospital between Jan 2011 and Dec 2021.Results:Lymph node metastasis and/or residual cancer was found in 23 patients (22%), including 12 cases of lymph node metastasis, 7 cases of residual cancer and 4 patients with both residual cancer and lymph node metastasis. Univariate analysis indicated that vascular infiltration, positive vertical margin, and female gender were risk factors for lymph node metastasis. Risk factors for residual cancer were tumors ≥2 cm in size, negative lift sign, infiltration depth of ≥1 000 μm, and positive horizontal and vertical margins. Multivariate Logistic regression analysis revealed that vascular invasion, positive vertical margins, and being female were independent risk factors for lymph node metastasis, while positive vertical margins was independent risk factor for residual cancer. Salvage surgery lasted for a median of 184 (156-233) minutes, with an estimated blood loss of 50 (20-100) ml and an average postoperative hospital stay of 9 (8-11) days. Seven cases of Clavein-Dindo Ⅱ or higher complications were observed, including pulmonary embolism in 1 case , anastomotic leakage in one, lymphatic fistula in one, bowel obstruction in 2 cases and urinary tract infection in 2 cases.Conclusion:Salvage surgery is mandatory for early endoscopic non-curative resection of colorectal cancer.

In the context of non-alcoholic fatty liver disease (NAFLD), characterized by dysregulated lipid metabolism in hepatocytes, the quest for safe and effective therapeutics targeting lipid metabolism has gained paramount importance. Sanhuang Xiexin Tang (SXT) and Baihu Tang (BHT) have emerged as prominent candidates for treating metabolic disorders. SXT combined with BHT plus Cangzhu (SBC) has been used clinically for Weihuochisheng obese patients. This retrospective analysis focused on assessing the anti-obesity effects of SBC in Weihuochisheng obese patients. We observed significant reductions in body weight and hepatic lipid content among obese patients following SBC treatment. To gain further insights, we investigated the effects and underlying mechanisms of SBC in HFD-fed mice. The results demonstrated that SBC treatment mitigated body weight gain and hepatic lipid accumulation in HFD-fed mice. Pharmacological network analysis suggested that SBC may affect lipid metabolism, mitochondria, inflammation, and apoptosis-a hypothesis supported by the hepatic transcriptomic analysis in HFD-fed mice treated with SBC. Notably, SBC treatment was associated with enhanced hepatic mitochondrial biogenesis and the inhibition of the c-Jun N-terminal kinase (JNK)/nuclear factor-kappa B (NF-κB) and extracellular signal-regulated kinase (ERK)/NF-κB pathways. In conclusion, SBC treatment alleviates NAFLD in both obese patients and mouse models by improving lipid metabolism, potentially through enhancing mitochondrial biogenesis. These effects, in turn, ameliorate inflammation in hepatocytes.

Oxalicine B ( 1) is an α-pyrone meroterpenoid with a unique bispirocyclic ring system derived from Penicillium oxalicum. The biosynthetic pathway of 15-deoxyoxalicine B ( 4) was preliminarily reported in Penicillium canescens, however, the genetic base and biochemical characterization of tailoring reactions for oxalicine B ( 1) has remained enigmatic. In this study, we characterized three oxygenases from the metabolic pathway of oxalicine B ( 1), including a cytochrome P450 hydroxylase OxaL, a hydroxylating Fe(II)/α-KG-dependent dioxygenase OxaK, and a multifunctional cytochrome P450 OxaB. Intriguingly, OxaK can catalyze various multicyclic intermediates or shunt products of oxalicines with impressive substrate promiscuity. OxaB was further proven via biochemical assays to have the ability to convert 15-hydroxdecaturin A ( 3) to 1 with a spiro-lactone core skeleton through oxidative rearrangement. We also solved the mystery of OxaL that controls C-15 hydroxylation. Chemical investigation of the wild-type strain and deletants enabled us to identify 10 metabolites including three new compounds, and the isolated compounds displayed potent anti-influenza A virus bioactivities exhibiting IC₅₀ values in the range of 4.0-19.9 μmol/L. Our studies have allowed us to propose a late-stage biosynthetic pathway for oxalicine B ( 1) and create downstream derivatizations of oxalicines by employing enzymatic strategies.

Objective:To evaluate the efficacy of preoperative three-dimensional (3D) image reconstruction combined with intraoperative dynamic ultrasonography (IOUS) in laparoscopic precision hepatectomy for intrahepatic bile duct stones.Methods:The clinical data of 66 patients with intrahepatic bile duct stones undergoing laparoscopic hepatectomy in the First People's Hospital of Fuyang District, Hangzhou from January 2018 to January 2023 were retrospectively analyzed, including 32 males and 34 females, aged (49.6±15.2) years old. Patients were divided into the study group ( n=32), who underwent laparoscopic precision hepatectomy using 3D reconstruction combined with IOUS, and the control group ( n=34), who underwent conventional laparoscopic hepatectomy. Perioperative data including the operation time, intraopera-tive blood loss, total volume of drainage on postoperative day (POD) 3, and the rates of complications were compared between the groups. Serum levels of interleukin-6 (IL-6), C-reactive protein (CRP), liver function indices including total bilirubin (TBil) and alanine aminotransferase (ALT) were monitored preoperatively and on POD 1, 3, 5, and 7. Results:The operation time was shorter in the study group [(178±17) min vs. (189±18) min, t=2.55, P=0.010]. The intraoperative blood loss was reduced in the study group [(218±19) ml vs. (395±21) ml, P<0.001]. The incidence of total volume of drainage >300 ml on POD 3 were comparable between the groups [9.4%(3/32) vs. 14.7%(5/34), P=0.507]. There were no significant differences in preoperative serum level of TBil, ALT, CRP and IL-6 between the groups (all P>0.05). Compared to the control group, serum levels of TBil, ALT and CRP in the study group were decreased on POD 1, 3, 5 and 7, and IL-6 was decreased on POD 1 and 3 (all P<0.05). The occurrences of postoperative bile leakage [9.4% (3/32) vs. 29.4% (10/34)] and liver cutting surface fluid accumulation [12.5% (4/32) vs. 35.3% (12/34)] and the rate of stone retention [3.0% (1/32) vs. 20.6% (7/34)] were lower in the study group (all P<0.05). Conclusion:Preoperative 3D image reconstruction combined with IOUS in laparoscopic precision hepatectomy for intrahepatic bile duct stones could reduce intra-operative blood loss, hepatic inflammatory response, and postoperative complications.

OBJECTIVE To evaluate the correlation between the solid dispersion(SD) powder properties and the relative crystallinity(RC) during SD recrystallization. METHODS Andrographolide was used as model drug, polyvinylpyrrolidone K30, polyethylene glycol 8000, Poloxam 188, Soluplus® as carrier materials, 12 SD powders were prepared by three preparation processes, and then the SD powder properties were determined. Afterwards, the principle component analysis and partial least squares analysis(PLS) were used to evaluate the correlation between the SD powder properties and RC during SD recrystallization. RESULTS The correlation model was successfully established by partial least square method between the SD powder properties and the RC. The VIP value of particle size parameter D(0.5) was >1.2, which indicated that the particle size was the key factor affecting the recrystallization of SD powder. CONCLUSION In practical work, SD powder with different particle size parameters can be obtained by different preparation methods or by adjusting the process parameters of the selected preparation method, so as to improve the recrystallization stability of SD.

Objective: To study laparoscopic ultrasound assisted hepatectomy in treatment of intrahepatic and extrahepatic bile duct stones. Methods: The data of 52 patients with hepatolithiasis who underwent laparoscopic hepatectomy from May 2014 to January 2019 at the Fuyang District First People's Hospital in Hangzhou were analyzed retrospectively. There were 28 men and 24 women. The median age was 56 years. Operative laparoscopic ultrasonography was used to detect the location, size, distribution of stones and their relations to blood vessels. A total of 43 patients underwent anatomic hepatectomy, while 38 patients underwent choledochoscopic stone extraction. A " T" tube was used according to intraoperative conditions. Results: Laparoscopic surgery was successfully carried out in 50 patients, while conversion to open surgery was required in 2 patients because of adhesions and bleeding. Laparoscopic ultrasonography revealed intrahepatic calcifications in 5 patients and choledochoscopy in 2 patients. Postoperative complications included 5 patients who devleoped abdominal abscesses. The operation time was (289.0±132.0) minutes. The intraoperative blood loss was (451.0±256.0) ml. The hospitalization after operation was (12.0±3.0) days. In 52 patients, 4 patients had residual stones and the residual rate was 7.7%. All of them were completely removed by T-tube sinus 8 weeks after operation. Conclusions Laparoscopic ultrasound helped to detect relevant bile ducts containing stones, reduced chance of bleeding in surgery, helped to clarify location and distribution of stones, improved accuracy of diagnosis, and reduced unnecessary hepatectomy by clearly defining intrahepatic bile duct stones intraoperatively. The residual intrahepatic and intrahepatic bile duct stones rates were reduced, and the safety and accuracy of the operations were improved.
