Anti-tumor traditional Chinese medicine has a long history of clinic application, in which the star molecules have always been the hotspot of modern drug research, but they are limited by the solubility, stability, targeting, bioactivity or toxicity of the monomer components of traditional Chinese medicine anti-tumor star molecules and other pharmacokinetic problems, which hinders the traditional Chinese medicine anti-tumor star molecules for further clinical translation and application. Currently, the nanosystems prepared by supramolecular technologies such as molecular self-assembly and nanomaterial encapsulation have broader application prospects in improving the anti-tumor effect of active components of traditional Chinese medicine, which has attracted extensive attention from scholars at home and abroad. In this paper, we systematically review the research progress in preparation of supramolecular nano-systems from anti-tumor star molecule of traditional Chinese medicine, and summarize the two major categories and ten small classes of carrier-free and carrier-based supramolecular nanosystems and their research cases, and the future development direction is put forward. The purpose of this paper is to provide reference for the research and clinical transformation of using supramolecular technology to improve the clinical application of anti-tumor star molecule of traditional Chinese medicine.

Objective: To identify the maximum tolerated dose (MTD) of docetaxel combined with a fixed dose of cisplatin (75 mg/m 2 ) delivered as hyperthermic intraperitoneal chemotherapy (HIPEC) in patients with ovarian cancer. Methods: In this phase I trial, a time-to-event Bayesian optimal interval design was used.Docetaxel was given at a starting dose of 60 mg/m2 and was increased in 5 mg/m2 increments until the MTD was determined or the maximum dose level of 75 mg/m2 was reached. The doselimiting toxicity (DLT) rate was set at 25%, with a total sample size of 30 patients. HIPEC was delivered immediately following debulking surgery at a target temperature of 43°C for 90 minutes. Results: From August 2022 to November 2022, 30 patients were enrolled. Among the patients who received a dose of docetaxel ≤65 mg/m2 , no DLT was reported. DLTs were observed in one patient who received 70 mg/m2 docetaxel (grade 3 anaemia) and in three patients who received 75 mg/m2 docetaxel (one case of grade 3 anaemia, one case of grade 3 hepatic impairment and one case of grade 4 thrombocytopenia). Patients treated with docetaxel 75 mg/m2 in combination with cisplatin 75 mg/m2 had an estimated DLT rate of 25%, which was the closest to the target DLT rate and was therefore chosen as the MTD. Conclusion Docetaxel, in combination with a fixed dose of cisplatin (75 mg/m2), can be used safely at intraperitoneal doses of 75 mg/m2 in ovarian cancer patients who received HIPEC (43°C, 90 minutes) following debulking surgery.

Objective: To explore the development of the pancreatic surgeon technique in a high-volume center. Methods: A total of 284 cases receiving pancreatic surgery by a single surgeon from June 2015 to December 2020 were retrospectively included in this study. The clinical characteristics and perioperative medical history were extracted from the medical record system of Zhongshan Hospital,Fudan University. Among these patients,there were 140 males and 144 females with an age (M (IQR)) of 61.0 (16.8) years(range: 15 to 85 years). The "back-to-back" pancreatic- jejunal anastomosis procedure was used to anastomose the end of the pancreas stump and the jejunal wall. Thirty days after discharge,the patients were followed by outpatient follow-up or telephone interviews. The difference between categorical variables was analyzed by the Chi-square test or the CMH chi-square test. The statistical differences for the quantitative data were analyzed using one-way analysis of variance or Kruskal-Wallis H test and further analyzed using the LSD test or the Nemenyi test,respectively. Results: Intraoperative blood loss in pancreaticoduodenectomy between 2015 and 2020 were 300,100(100),100(100),100(0),100(200) and 150 (200) ml,respectively. Intraoperative blood loss in distal pancreatectomy was 250 (375),100 (50),50 (65), 50 (80),50 (50),and 50 (100) ml,respectively. Intraoperative blood loss did not show statistical differences in the same operative procedure between each year. The operative time for pancreaticoduodenectomy was respectively 4.5,5.0(2.0),5.5(0.8),5.0(1.3),5.0(3.3) and 5.0(1.0) hours in each year from 2015 to 2020,no statistical differences were found between each group. The operating time of the distal pancreatectomy was 3.8 (0.9),3.0 (1.5),3.0 (1.8),2.0 (1.1),2.0 (1.5) and 3.0(2.0) hours in each year,the operating time was obviously shorter in 2018 compared to 2015 (P=0.026) and 2020 (P=0.041). The median hospital stay in 2020 for distal pancreatectomy was 3 days shorter than that in 2019. The overall incidence of postoperative pancreatic fistula gradually decreased,with a incident rate of 50.0%,36.8%,31.0%,25.9%,21.1% and 14.8% in each year. During this period,in a total of 3,6,4,2,0 and 20 cases received laparoscopic operations in each year. The incidence of clinically relevant pancreatic fistula (grade B and C) gradually decreased,the incident rates were 0,4.8%,7.1%,3.4%,4.3% and 1.4%,respectively. Two cases had postoperative abdominal bleeding and received unscheduled reoperation. The overall rate of unscheduled reoperation was 0.7%. A patient died within 30 days after the operation and the overall perioperative mortality was 0.4%. Conclusion: The surgical training of a high-volume center can ensure a high starting point in the initial stage and steady progress of pancreatic surgeons,to ensure the safety of pancreatic surgery.

ObjectiveTo analyze the epidemiological characteristics of varicella in Minhang District， Shanghai from 2013 to 2022， and to evaluate the impact of adjusting the varicella vaccination program to a two-dose regimen and its inclusion in the Shanghai immunization program on the incidence of varicella. MethodsData on reported varicella cases from 2013 to 2022 in Minhang District were collected. Interrupted time series analysis and segmented regression models were used to analyze the changes in varicella incidence before and after the adjustment of varicella immunization strategies. ResultsFrom 2013 to 2022， the average annual incidence of varicella was 76.58/100 000， with the highest incidence in 2017 （119.21/100 000） and the lowest in 2022 （27.02/100 000）. The varicella incidence exhibited seasonal patterns with peaks occurring from March to June and October to January of the following year. Prior to the adjustment of varicella immunization strategies （2013‒2017）， the varicella incidence showed an upward trend （z=2.20， P=0.03）， while after the adjustment （2018‒2022）， a adownward trend was observed （2018‒2022） （z=-2.25， P=0.02）. Interrupted time series analysis showed that following the adjustment of varicella immunization strategies， an immediate change of -33.91/100 000 （t=-4.35， P<0.001） in varicella incidence was observed， and the incidence slope was -17.59/100 000 with a decline of 28.61/100 000 （t=-12.16， P<0.001） compared to before inclusion. ConclusionThe incidence of varicella in Minhang District， Shanghai from 2013 to 2022 exhibits distinct seasonal patterns. After adjusting the varicella vaccination program to a two-dose regimen and incorporating it into the immunization program， the second dose of varicella vaccine administration substantially increases. As a result， the rising trend of varicella incidence is effectively controlled， and the incidence level decreases significantly， showing a sustained downward trend.

Objective: To summarize the clinical characteristics of tumour necrosis factor receptor-associated periodic syndrome (TRAPS) in children. Methods: The clinical manifestations, laboratory tests, genetic testing and follow-up of 10 children with TRAPS from May 2011 to May 2021 in 6 hospitals in China were retrospectively analyzed. Results: Among the 10 patients with TRAPS, including 8 boys and 2 girls. The age of onset was 2 (1, 5) years, the age of diagnosis was (8±4) years, and the time from onset to diagnosis was 3 (1, 7) years. A total of 7 types of TNFRSF1A gene variants were detected, including 5 paternal variations, 1 maternal variation and 4 de novo variations. Six children had a family history of related diseases. Clinical manifestations included recurrent fever in 10 cases, rash in 4 cases, abdominal pain in 6 cases, joint involvement in 6 cases, periorbital edema in 1 case, and myalgia in 4 cases. Two patients had hematological system involvement. The erythrocyte sedimentation rate and C-reactive protein were significantly increased in 10 cases. All patients were negative for autoantibodies. In the course of treatment, 5 cases were treated with glucocorticoids, 7 cases with immunosuppressants, and 7 cases with biological agents. Conclusions: TRAPS is clinically characterized by recurrent fever accompanied by joint, gastrointestinal, skin, and muscle involvement. Inflammatory markers are elevated, and autoantibodies are mostly negative. Treatment mainly involves glucocorticoids, immunosuppressants, and biological agents.

OBJECTIVE: To investigate the protective effects of curcumin(CUR) and its mechanism on a rat model of neurotoxicity induced by manganese chloride (MnCl₂), which mimics mangnism. METHODS: Sixty male SD rats were randomly divided into 5 groups, with 12 rats in each group. Control group received 0.9% saline solution intraperitoneally (ip) plus double distilled water (dd) H₂O intragastrically (ig), MnCl₂ group received 15 mg/kg MnCl₂(Mn²⁺ 6.48 mg/kg) intraperitoneally plus dd H₂O intragastrically, CUR group received 0.9% saline solution intraperitoneally plus 300 mg/kg CUR intragastrically, MnCl₂+ CUR1 group received 15 mg/kg MnCl₂ intraperitoneally plus 100 mg/kg curcumin intragastrically, MnCl₂+ CUR2 group received 15 mg/kg MnCl₂ intraperitoneally plus 300 mg/kg CUR intragastrically, 5 days/week, 4 weeks. Open-field and rotarod tests were used to detect animals' exploratory behavior, anxiety, depression, movement and balance ability. Morris water maze (MWM) experiment was used to detect animals' learning and memory ability. ICP-MS was used to investigate the Mn contents in striata. The rats per group were perfused in situ, their brains striata were removed by brains model and fixed for transmission electron microscope (TEM), histopathological and immunohistochemistry (ICH) analyses. The other 6 rats per group were sacrificed. Their brains striata were removed and protein expression levels of transcription factor EB (TFEB), mammalian target of rapamycin (mTOR), p-mTOR, Beclin, P62, microtubule-associated protein light chain-3 (LC3) were detected by Western blotting. Terminal deoxynucleotidyl transterase-mediated dUTP nick end labeling (TUNEL) staining was used to determine neurocyte apoptosis of rat striatum. RESULTS: After exposure to MnCl₂ for four weeks, MnCl₂-treated rats showed depressive-like behavior in open-field test, the impairments of movement coordination and balance in rotarod test and the diminishment of spatial learning and memory in MWM (P < 0.05). The striatal TH⁺ neurocyte significantly decreased, eosinophilic cells, aggregative α-Syn level and TUNEL-positive neurocyte significantly increased in the striatum of MnCl₂ group compared with control group (P < 0.05). Chromatin condensation, mitochondria tumefaction and autophagosomes were observed in rat striatal neurocytes of MnCl₂ group by TEM. TFEB nuclear translocation and autophagy occurred in the striatum of MnCl₂ group. Further, the depressive behavior, movement and balance ability, spatial learning and memory ability of MnCl₂+ CUR2 group were significantly improved compared with MnCl₂ group (P < 0.05). TH+ neurocyte significantly increased, the eosinophilic cells, aggregative α-Syn level significantly decreased in the striatum of MnCl₂+ CUR2 group compared with MnCl₂ group. Further, compared with MnCl₂ group, chromatin condensation, mitochondria tumefaction was alleviated and autophagosomes increased, TFEB-nuclear translocation, autophagy was enhanced and TUNEL-positive neurocyte reduced significantly in the striatum of MnCl₂+ CUR2 group (P < 0.05). CONCLUSION Curcumin alleviated the MnCl₂-induced neurotoxicity and α-Syn aggregation probably by promoting TFEB nuclear translocation and enhancing autophagy.

The aim of this study was to compare crocins in the fruit of Gardenia jasminoides and Gardenia jasminoides var. radicans. Acchrom XCharge C_(18) column(4.6 mm×250 mm, 5 μm) was used for separation, with mobile phase of acetonitrile and 0.1% formic acid for gradient elution. The detection wavelength was set at 440 nm with a flow rate of 1.0 mL·min~(-1), and the column temperature was 30 ℃. The high performance liquid chromatography(HPLC) fingerprint of crocin in Gardenia species was established by testing 20 batches of G. jasminoides and 8 batches of G. jasminoides var. radicans samples from different sources, and UHPLC-ESI-Orbitrap-MS/MS technology and reference substances were used to predict and identify the common peaks. The results showed that 20 common chromatographic peaks from the samples were selected and the structures of 16 common peaks were predicted by mass spectrum. Four common peaks(crocin Ⅰ, Ⅱ, Ⅲ, and Ⅳ) were identified by the comparison with reference substances. The content of crocin Ⅰ, Ⅱ, Ⅲ, and Ⅳ was determined simultaneously under the same chromatographic condition, and both the system suitability and the methodological investigation results met the requirements of content determination. The relative similarity of HPLC fingerprint of 28 samples to the reference fingerprint was above 0.98. The results of cluster analysis(CA) showed that G. jasminoides and G. jasminoides var. radicans were separately grouped into one group. In the 20 batches of G. jasminoides, the content of crocin Ⅰ, Ⅱ, Ⅳ, and Ⅲ was between 3.58-9.58, 0.230-1.452, 0.014 5-0.135, and 0.301-1.12 mg·g~(-1), respectively, and the total content was between 4.12-12.25 mg·g~(-1). In the 8 batches of G. jasminoides var. radicans, the content of crocin Ⅰ, Ⅱ, Ⅳ, and Ⅲ was between 5.84-11.48, 0.308-0.898, 0.010 6-0.025 5, and 0.675-1.34 mg·g~(-1), respectively, and the total content was between 6.97-13.72 mg·g~(-1). The existing results showed that there is a certain similarity between G. jasminoides and G. jasminoides var. radicans in the composition of crocin, which needs further proved by more batches of samples. The method established in this paper provides references for the quality control of G. jasminoides, G. jasminoides var. radicans, and related products.
