Liumotang comes from the Yuan dynasty's Effective Prescription Handed Down for Generations of Physicians. It is composed of six medicinal materials： Arecae Semen， Aquilariae Lignum Resinatum， Aucklandiae Radix， Linderae Radix， Rhei Radix et Rhizoma， and Aurantii Fructus. It is a classical formula for treating abdominal pain due to Qi stagnation and constipation accompanied by heat. This study systematically collated the records of Liumotang in ancient medical books and modern clinical literature and conducted in-depth analysis and textual research on its formula source， main diseases， composition， dosage， medical books， container capacity， processing， preparation method， usage， drug basis， formula meaning， and other key information， so as to provide a powerful reference for the development and clinical application of compound preparations of the classical formula Liumotang. The results show that Liumotang was first seen in Effective Prescription Handed Down for Generations of Physicians， and many medical books of the past dynasties have imitated this. In terms of drug basis， the dried and mature seeds of the palm plant Areca catechu， resin-containing wood of the Daphneaceae plant Aquilaria sinensis， the dried roots of the Asteraceae plant woody Aucklandia lappa， the dried tuber root of the Lauraceae plant Lindera aggregata， the dried roots and rhizomes of the knotweed plant， R. palmatum， R.tangutikum， and R. officinale， and the dried and unripe fruits of the citrus genus C. aurantium and its cultivated varieties from the family Rutaceae were selected. In terms of dosage， through the textual research on bowls in the Ming and Qing dynasties， combined with the conversion of medicines and bowl capacity in the Qing dynasty， it was estimated that the dosage of each drug in the Yuan dynasty was 10.86 g. In the Ming and Qing dynasties， the dosage of drugs was mostly equal， but the dosage of drugs was somewhat different. In terms of processing， preparation method， and usage， in the medical books of the past dynasties， the processing of drugs has slightly changed， but raw drugs are used in all preparations. The preparation method and usage did not change much during the Yuan， Ming， and Qing dynasties， except for certain differences in dosage. In terms of syndrome， Liumotang was first used to treat abdominal pain due to Qi stagnation and constipation accompanied by heat. Medical books of the past dynasties often omit the symptoms of heat. In modern clinical practice， Liumotang is mainly used in the digestive system and urinary system diseases and is mostly used to treat constipation-predominant irritable bowel syndrome， biliary reflux gastritis， functional constipation， slow transit constipation， and other diseases， with no adverse reactions found yet. The above results provide a reliable scientific basis for the development and clinical treatment of Liumotang compound preparations.

OBJECTIVE To systematically evaluate the efficacy and safety of tislelizumab in the treatment of advanced non- small cell lung cancer （NSCLC）. METHODS Computerized searches were conducted in PubMed， Embase， the Cochrane Library， CNKI， Wanfang and other Chinese and English databases to collect randomized controlled trials （RCTs） on tislelizumab for advanced NSCLC. The search period was from the establishment of the databases to December 2024. After strictly screening the literature， extracting data and conducting quality evaluations in accordance with the inclusion and exclusion criteria， a meta-analysis was performed using RevMan 5.3 and Stata 16.0 software. RESULTS A total of 18 RCTs involving 2 337 patients were included， with 1 283 in the experimental group and 1 054 in the control group. The meta-analysis results showed that the objective response rate [RR＝1.61， 95%CI （1.48， 1.75）， P＜0.000 01]， disease control rate [RR＝1.21， 95%CI （1.13， 1.29）， P＜0.000 01]， progression free survival [HR＝0.55， 95%CI （0.45， 0.66）， P＜0.000 01]， and overall survival [HR＝0.78， 95%CI（0.62， 0.97）， P＝0.03] were significantly better in the experimental group than in the control group. There was no statistically significant difference in the incidence of adverse reactions between the two groups [RR＝1.00， 95%CI （0.73， 1.37）， P＝1.00]； among the common adverse reactions， only the incidence of liver function impairment was significantly higher in the experimental group than in the control group [RR＝1.30， 95%CI （1.10， 1.54）， P＜0.01]. CONCLUSIONS Tislelizumab in combination with chemotherapy or targeted drugs significantly improves the efficacy in patients with advanced NSCLC without increasing the risk of adverse reactions overall. However， liver function should be closely monitored during treatment.

Objective To establish a dynamic model of lipopolysaccharide-induced acute lung injury in mice based on the NLRP3/Caspase-1/gasdermin D(GSDMD)pyroptosis pathway,and observe the result ing lung injury at different time points.We aimed to identify the optimal time for modelling according to the injury at different time points and the expression of pyroptosis pathway-related proteins,to lay the foundation for animal models for subsequent experiments.Methods Fifty-four 6～8 weeks old male SPF BALB/c mice were divided randomly into nine groups,including Con group and model groups at 1,3,6,12,18,24,48,and 72 h.Body weight and lung tissue were detected by general and pathological observations and semi-quantitative scoring,including lung index,lung water content,and wet and dry weight ratio.The white blood cell count and concentrations of tumor necrosis factor-α,interleukin(IL)-6,IL-1β,IL-18,and BCA protein were detected in bronchoalveolar lavage fluid(BALF).The classic pyroptosis pathway-related proteins NLRP3,pro-Caspase 1,Caspase 1,and GSDMD were detected by Western Blot.Results Body weight decreased in all experimental groups,with the most significant weight loss in the 24 and 48 h groups.Gross observation and pathological examination of lung tissue showed that the most severe lung injury occurred at 24～72 h,with significant differences between each group and the control group.The lung index,lung water content,and wet/dry weight ratio were also significantly increased at 24～72 h.White blood cells in BALF started to increase from 6 h after model initiation,48 h can reach a peak,72 h all keep increasing.IL-18 in BALF began to increase at 24 h and continued to increase at 72 h.The inflammatory factors tumor necrosis factor-α,IL-1β,IL-6 were highest at 6 h and significantly reduced at 48 h.Protein concentrations in BALF were significantly increased within 24,48,and 72 h compared with those in the control group.The pyroptosis pathway proteins NLRP3,pro-Caspase-1,Caspase-1,and GSDMD were significantly enhanced in each time series,and channel protein expression was significantly enhanced at 24～72 h compared with that in the Con group.Conclusions Comprehensive analysis of experimental indicators,inflammatory factors,and pathway proteins at different times showed that the mechanism of pyroptosis was closely related to the occurrence and progression of acute lung injury.Expression of the pyroptosis pathway was most obvious and lung injury was most serious at 24～48 h.This study provides a model reference and experimental basis for subsequent studies of the specific mechanism and intervention targets of acute lung injury.

Sphincter of Oddi dysfunction (SOD) refers to the abnormal physiological function of sphincter of Oddi, which causes a series of syndromes in biliary tract, pancreas and liver. At present, the related research of SOD is becoming a hot spot, but its pathogenesis is not clear. This article will review the domestic and international literatures on SOD, review the advantages and disadvantages of experimental animals such as rabbits, dogs and guinea pigs, and analyze the characteristics of drugs and surgical modeling, so as to provide references for future related model establishment.

Objective:To study the changes in the sphincter of Oddi pressure in rabbits after bilateral vagus nerve trunk severance and the therapeutic effect of Qingre Lidan Decoction, to provide a new way for the treatment of sphincter of Oddi dysfunction.Methods:Twenty-four 1.5~2.0 kg New Zealand Large White rabbits of either gender were randomly selected and divided into the control group, the model group, and the treatment group. In the control group, only pyloroplasty was performed; in the model group and the treatment group, pyloroplasty plus bilateral vagus nerve trunk dissection at the level of the diaphragm were performed, and in the treatment group, one month of gavage treatment with Qingre Lidan Decoction was carried out 7 days after the operation. Multi-channel bio-signal acquisition system was used to record the pressure changes of the sphincter of Oddi in rabbits of each group; ELISA was used to detect the changes of inflammatory factors IL-6 and tumor necrosis factor TNF-α in the serum of rabbits.Results:The pressure of the sphincter of Oddi in the model group was significantly higher than those in the control group [low-pressure area: (51.95±0.35) mmHg (1 mmHg=0.133 kPa) vs (21.60±1.13) mmHg ( P<0.05) ; High pressure area: (60.75±0.49) mmHg vs (20.70±0.85) mmHg ( P<0.05)], the pressure of sphincter of Oddi in the treatment group of Qingre Lidan Decoction was lower than that of the model group [low-pressure area: (22.70±1.13) mmHg vs (51.95±0.35) mmHg ( P<0.05); high-pressure area: (32.15±0.49) mmHg vs (60.75±0.49) mmHg ( P<0.05)]. Serum IL-6 and TNF-αwere significantly elevated in the model group compared to the control group; IL-6 and TNF-α levels were decreased in the treatment group compared to the model group, and the differences were statistically significant ( P<0.05). Conclusion:Bilateral vagus nerve trunk severance leads to Oddi sphincter dysfunction, and treatment with Qingre Lidan Decoction could improve Oddi sphincter dysfunction.

Despite being a common therapy for hepatocellular carcinoma (HCC), insufficient thermal ablation can leave behind tumor residues that can cause recurrence. This is believed to augment M2 inflammatory macrophages that usually play a pro-tumorigenic role. To address this problem, we designed d-mannose-chelated iron oxide nanoparticles (man-IONPs) to polarize M2-like macrophages into the antitumor M1 phenotype. In vitro and in vivo experiments demonstrated that man-IONPs specifically targeted M2-like macrophages and accumulated in peri-ablation zones after macrophage infiltration was augmented under insufficient microwave ablation (MWA). The nanoparticles simultaneously induced polarization of pro-tumorigenic M2 macrophages into antitumor M1 phenotypes, enabling the transformation of the immunosuppressive microenvironment into an immunoactivating one. Post-MWA macrophage polarization exerted robust inhibitory effects on HCC progression in a well-established orthotopic liver cancer mouse model. Thus, combining thermal ablation with man-IONPs can salvage residual tumors after insufficient MWA. These results have strong potential for clinical translation.

Objective    To explore the surgical technique and preliminary results of endoscopic nipple-sparing mastectomy (E-NSM) and immediate pre-pectoral implant-based breast reconstruction (BR) with titanium-coated polypropylene mesh (TiLoop Bra) via single axillary incision for breast cancer patients. Methods    The clinical data of 9 consecutive female patients who underwent E-NSM and immediate pre-pectoral implant-based BR with TiLoop Bra from  March to May 2021 were retrospectively analyzed. The mean age of patients was 40.6 (22-60) years. The operation time, early complications were collected, and the patients' social and mental health, breast satisfaction and chest function before and after the operation were assessed with the BREAST-Q questionnaire. Results    All the patients had unicentric tumor with a mean diameter of 2.4 (0.6-4.7) cm. The mean distance from the tumor to the nipple was 2.5 (2-4) cm. There were 2 patients with tumor stage 0 and 7 patients with stageⅠ. The mean operation time was 161.1 (125-201) min, the mean blood loss was 41.1 mL and the hospital stay time was 1.5 d. There were 5 patients in the day-care unit. All the patients were successfully followed up with a median follow-up time of 1 (1-2) month. One (11.1%) patient with depigmentation of the nipple-areola complex caused by mild ischemia. None of the patients had incision complications, subcutaneous emphysema, hematoma, infection, nipple-areola or skin flaps necrosis, implant loss. During the follow-up period, no local/regional recurrence or distant metastasis was found. Chest well-being was decreased in the first month after the surgery compared with preoperative status, and the difference was statistically significant (P=0.001). There was no statistical difference in the breast satisfaction or psychosocial function scores between pre- and post-operation (P>0.05). Conclusion    E-NSM and immediate pre-pectoral implant-based BR with TiLoop Bra via single axillary incision has minimal trauma, rapid postoperative recovery, short operation time, few early complications and good early cosmetic effect, and the short-term result is satisfactory.

The traditional view is that breast reconstruction is not an option for day surgery center. As a result, few hospitals in the world conduct this operation in day surgery center. Endoscopic breast reconstruction with liposuction and robot-assisted breast reconstruction are minimally invasive surgeries for breast cancer patients, but they cannot be carried out in the day surgery center due to long operation time. The novel endoscopic-assisted immediate implant-based breast reconstruction after nipple sparing mastectomy through a single axillary incision for breast cancer patients has been successfully conducted in the day surgery center in our hospital due to short operation time and small trauma. Standardized management of the complete process from the patient selection to follow-up after discharge brings rapid recovery and few complications. At the same time, the development of endoscopic surgery makes the breast almost scarless and improves aesthetic results. Therefore, the mode of endoscopic-assisted reconstruction in the day surgery center of our hospital is expected to be popularized in the whole country.

In order to study the effect of human deoxyribonuclease I(DNase I)on neutrophil extracellular traps(NETs)degradation, genetic engineering bacteria E. coli Rosetta(DE3)/pET32a-His-DNase I was constructed. The fusion protein His-DNase I was induced by lactose, and purified by Ni-affinity chromatography. Mouse neutrophils were extracted and stimulated with phorbol-12-myristate-13-acetate(PMA)to form NETs. The degradation activity of the fusion protein on NETs was detected by SytoxGreen and fluorescence microscopy. The results showed that the purified His-DNase I had high nuclease activity. This study provided the research foundation for further exploration of the clinical application of DNase I.

Objective To investigate the clinical manifestation, inherited pattern and the related factor of Hunting?ton disease families. Method The clinical data from 12 HD families was collected from 2013-2014. Patients received the genetic test and neurological evaluation including motor, cognitive and problem of behavior. Results There were 12 patients having the IT15 gene dynamic mutations, including 1 Juvenile Huntington disease patient and 3 pre-symptomat?ic mutant gene carriers. The average CAG repeats of these patients was between the range of 40 to 60, and the average on?set age ranged from 13 to 54 year-old. Positive family history and genetic anticipation could be observed. Patients pre?sented with different clinical manifestations at the early stage while had typical chorea movements, declined cognitive and psychiatric symptoms at the late stage of the illness. Conclusions There are typical triad symptoms in the late stage but not in the early stage nor pre-symptom stage illness. Clinical manifestation and the neuroimaging are both of great ref?erence value, and the genetic test is essential for final diagnosis.
