Houpo Sanwutang， included in the Catalogue of Ancient Classical Prescriptions （Second Batch）， was first recorded in the Synopsis of Golden Chamber written by ZHANG Zhongjing from the Eastern Han dynasty and was modified by successive generations of medical experts. A total of 37 pieces of effective data involving 37 ancient Chinese medical books were retrieved from different databases. Through literature mining， statistical analysis， and data processing， combined with modern articles， this study employed bibliometrics to investigate the historical origin， composition， decoction methods， clinical application， and other key information. The results showed that the medicinal origin of Houpo Sanwutang was clearly documented in classic books. Based on the conversion of the measurements from the Han Dynasty， it is recommended that 110.4 g Magnolia Officinalis Cortex， 55.2 g Rhei Radix et Rhizoma， and 72 g Aurantii Fructus Immaturus should be taken. Magnolia Officinalis Cortex and Aurantii Fructus Immaturus should be decocted with 2 400 mL water first， and 1 000 mL should be taken from the decocted liquid. Following this， Rhei Radix et Rhizoma should be added for further decoction， and then 600 mL should be taken from the decocted liquid. A single dose of administration is 200 mL， and the medication can be stopped when patients restore smooth bowel movement. Houpo Sanwutang has the effect of moving Qi， relieving stuffiness and fullness， removing food stagnation， and regulating bowels. It can be used in treating abdominal distending pain， guarding， constipation， and other diseases with the pathogenesis of stagnated heat and stagnated Qi in the stomach. The above results provide reference for the future development and research of Houpo Sanwutang.

OBJECTIVE: To summarize the research progress on the mechanism related to traumatic brain injury (TBI) to promote fracture healing, and to provide theoretical basis for clinical treatment of fracture non-union. METHODS: The research literature on TBI to promote fracture healing at home and abroad was reviewed, the role of TBI in fracture healing was summarized from three aspects of nerves, body fluids, and immunity, to explore new ideas for the treatment of fracture non-union. RESULTS: Numerous studies have shown that fracture healing is faster in patients with fracture combined with TBI than in patients with simple fracture. It is found that the expression of various cytokines and hormones in the body fluids of patients with fracture and TBI is significantly higher than that of patients with simple fracture, and the neurofactors released by the nervous system reaches the fracture site through the damaged blood-brain barrier, and the chemotaxis and aggregation of inflammatory cells and inflammatory factors at the fracture end of patients with combined TBI also differs significantly from those of patients with simple fracture. A complex network of humoral, neural, and immunomodulatory networks together promote regeneration of blood vessels at the fracture site, osteoblasts differentiation, and inhibition of osteoclasts activity. CONCLUSION TBI promotes fracture healing through a complex network of neural, humoral, and immunomodulatory, and can treat fracture non-union by intervening in the perifracture microenvironment.

Tingli Dazao Xiefeitang is a classic formula for treating lung abscesses and thoracic fluid retention， recognized throughout history and included in the Catalogue of Ancient Classic Formulas （Second Batch）. This article employs bibliometric methods to investigate and analyze the source， origin， and key information of Tingli Dazao Xiefeitang， providing a theoretical basis for the development and application of this renowned formula. The results show that Tingli Dazao Xiefeitang first appears in Synopsis of the Golden Chamber （Jin Kui Yao Lue）， where three clinical applications are recorded. The original text clearly states that this formula is used to treat lung abscesses and thoracic fluid retention， with symptoms such as inability to lie down due to wheezing， chest and rib fullness， facial edema， inability to rest due to thoracic fluid retention， and cough inversion. This aligns with findings from ancient application research. In later generations， the methods proposed by ZHANG Zhongjing were predominantly used for medication and formulation. Modern applications of Tingli Dazao Xiefeitang focus primarily on the respiratory system， with pleural effusion being the most common condition. For the preparation and decoction， a single dose of 5 g of Descurainiae Semen Lepidii Semen （dried and mature seeds of Lepidium apetalum） processed as stir-fried seeds and 36 g of Jujubae Fructus （dried and mature fruit of Ziziphus jujuba） prepared as raw materials were recommended. Then 600 mL of water was added and Jujubae Fructus was first boiled until the volume reduced to 400 mL. After filtering out the residue， the supernatant was retained and mixed with stir-fried Descurainiae Semen Lepidii Semen， followed by boiling to 200 mL， which should be consumed all at once. This research provides a theoretical basis for the development and application of this formula.

BACKGROUND:The remediation and treatment of bone defects present considerable challenges,with a variety of clinical intervention strategies available.One such approach,the Masquelet technique,has demonstrated high rates of success and reliable outcomes and is currently employed in clinical practice.However,the underlying mechanisms of this technique remain incompletely understood,and certain challenges persist in its clinical application,indicating that this technique is not yet fully mature. OBJECTIVE:To compile and categorize the biomaterials currently employed in research aimed at improving the Masquelet technique,in order to provide insights and references for the further development of this technique. METHODS:A literature search of the China National Knowledge Infrastructure and PubMed databases was conducted,spanning publications from January 2013 to November 2022.The search terms used included"Masquelet technique;induced membrane technique;induced membrane;biomaterial;bone defect"in both Chinese and English.A total of 58 articles meeting the inclusion criteria were reviewed. RESULTS AND CONCLUSION:(1)The emergence and continual development of the Masquelet technique provide a therapeutic strategy for treating bone defects.Some researchers are focusing on developing superior spacer materials,autograft substitutes,and membrane materials that mimic the properties of the induced membrane,to simplify the two-stage procedure,shorten treatment duration,and reduce patient distress.(2)Calcium sulfate,silicone,poly(lactic-co-glycolic acid),and polypropylene can replace polymethylmethacrylate bone cement to form induced membranes in animal experiments or clinical applications,each with their advantages.Contrary to expectations,common materials such as titanium and polyvinyl alcohol sponge cannot replace polymethylmethacrylate bone cement.(3)Autograft substitutes are diverse,with allograft bone,β-tricalcium phosphate,absorbable gelatin sponge,α-calcium sulfate hemihydrate,bioactive glass,titanium,and tantalum demonstrating their ability to reduce the quantity of autologous cancellous bone graft required in the second stage of the procedure.Among them,allograft bone,β-tricalcium phosphate,bioactive glass,titanium and tantalum can replace autogenous bone as grafts,and other materials need to be mixed with autogenous bone,in both clinical and fundamental experiments.(4)Biomimetic-induced membranes,human amnion,human decellularized dermis,polytetrafluoroethylene,and even autogenous cortical bone have been shown to possess properties similar to the induced membrane.(5)Most of the application and research of biomaterials in this technology still exist in the stage of basic research and have not been applied in clinical practice or popularized on a large scale,but the above materials can provide more sufficient theoretical basis and new ideas for the exploration of Masquelet technical mechanism,the improvement of surgical methods and clinical application.

Purpose To detect the expression of PP1A and GSDME and the abundance of CD8+T lymphocytes in colorectal cancer,and to explore the correlation and clinical significance of PP1A and GSDME mediated pyroptosis.Methods GEPIA da-tabase was applied to analyze the mRNA expression of PP1A and GSDME in colorectal cancer and normal tissues.Western blot assay was used to detect the expression of PP1A in colorectal cancer and the corresponding normal mucosa.Immunohisto-chemistry was applied to detect the expression of PP1A and GS-DME and CD8+T lymphocytes abundance in 107 colorectal car-cinomas and normal mucosa adjacent to the carcinomas.Spearman rank correlation was used to analyze the correlation between PP1A,GSDME and CD8+T cells abundance.Results The GEPIA database search showed that mRNA expression of PP1A and GSDME in colorectal cancer differed compared to normal tissues(P＜0.05).Western blot analysis showed that the relative expression of PP1A in colorectal cancer tissue was significantly higher than that in para-cancerous tissues(0.937 vs 0.643,P＜0.001).Immunohistochemical results showed that the expression of PP1A in colorectal cancer tissues was signifi-cantly higher than that in normal mucosa(P＜0.05).The ex-pression of GSDME in cancer tissue was closely correlated with patients'age,clinical stage and mismatch repair proteins(P＜0.05),and the distribution of CD8+T cells in the cancer infil-tration front was significantly higher than that in the normal mu-cosa,and the distribution of CD8+T cells in the cancer was cor-related with pT stage,clinical stage and lymph node metastasis.Spearman correlation analysis showed that PP1A was negatively correlated with GSDME expression(r=-0.196,P＜0.05).The overall survival PP1A-positive colorectal cancer patients was worse than that of PP1A-negative patients(P＜0.05),and the prognosis of patients was correlated with the degree of differentia-tion,lymph node metastasis,pT stage and clinical stage.Posi-tive expression of PP1A,degree of differentiation,clinical stage,pT stage and lymph node metastasis are independent risk factors affecting the prognosis of colorectal cancer patients.Conclusion PP1A is highly expressed in colorectal cancer and negatively correlated with GSDME-mediated cell pyroptosis,and the differ-ential expression of both is closely related to the progression and prognosis of colorectal cancer,which can be used as a potential indicator for judgment of the prognosis of colorectal cancer pa-tients.The differential distribution of CD8+T cells may be asso-ciated with GSDME-mediated cell pyroptosis and tumor develop-ment.

Purpose To investigate the clinicopathological significance and prognostic value of oral cancer overexpressed 1(ORAOV1)in esophageal squamous cell carcinoma(ESCC).Methods The mRNA expression of ORAOV1,ERK1 and ERK2 in 140 ESCC and 39 esophageal squamous intraepithelial neoplasia(ESIN)and 140 adjacent normal mucosal tissues were detected by RT-PCR.The relationship between their overexpres-sion and clinicopathological features was analyzed in ESCC pa-tients.Spearman correlation analysis was used to explore the correlation between ORAOV1 and ERK1 and ERK2.Results The expression level of ORAOV1 mRNA(13.158±2.246)with ESCC was significantly higher than that of low-grade ESIN(4.974±1.317),high-grade ESIN(7.398±1.891)and adja-cent tissues(1.000±0).The differences were significant(P＜0.01).High expression of ORAOV1 mRNA was positively cor-related with ESCC clinical stage and lymph node metastasis(all P＜0.05).Spearman analysis showed that the expression level of ORAOV1 mRNA was positively correlated with the expression levels of ERK1 mRNA and ERK2 mRNA in ESCC.Kaplan-Meier survival curve analysis showed that the overall survival of ESCC patients with high expression of ORAOV1 was significantly lower than that of patients with low expression,and the differ-ence was significant(P＜0.05).Conclusion The expression level of ORAOV1 gradually increases during the occurrence and development of ESCC,which is an independent prognostic factor of ESCC and is expected to become a new molecular target for early diagnosis and treatment of ESCC.

Objective:To explore the method and effect of aesthetic reconstruction of distal segment of finger with modified second toe nail flap while retains the full length of the second toe.Methods:From April 2018 to June 2020, 16 patients with degloving injury of distal segment of fingers were treated. The patients were 11 males and 5 females aged 18 to 45 years in an average of 29 years. All injuries were degloving injury of the distal segment of finger, including 5 index fingers, 7 middle fingers, 3 ring fingers and 1 little finger. The time from injury to operation was 0.5-3.0 hours, with an average of 1.5 hours. The second toe nail flap was used for the reconstruction. After the dorsal flap of the second toe was rotated to the plantar side of the foot, the donor site defect was repaired by a skin graft. The regular follow up reviews were carried out.Results:All 16 flaps survived except 1 flap had necrosis and underwent toe amputation of the distal segment of the second toe. All patients entered follow-up for 4-12 months, with an average of 5.7 months. The blood supply of all flaps was good. After the flaps having atrophied, they were equivalent to the diameter of the body of normal fingers with the TPD at 6.5(4-10) mm; All patients returned to work. According to the Evaluation Standard of Upper Limb Function of Chinese Hand Surgery Society, 13 cases were graded as excellent, 2 were good and 1 was fair.Conclusion:The techniques of modified second toe toenail flap in aesthetic reconstruction of the distal segment of a finger can effectively restore the length and aesthetic appearance of the affected finger, without sacrificing the donor toe. Clinical application of it should be promoted.

Objective:To analyze the risk factors of bronchopulmonary dysplasia(BPD)in very preterm infants(VPI), and to provide scientific basis for the prevention and treatment of BPD in VPI.Methods:A prospective multicenter study was designed to collect the clinical data of VPI in department of neonatology of 28 hospitals in 7 regions from September 2019 to December 2020.According to the continuous oxygen dependence at 28 days after birth, VPI were divided into non BPD group and BPD group, and the risk factors of BPD in VPI were analyzed.Results:A total of 2 514 cases of VPI including 1 364 cases without BPD and 1 150 cases with BPD were enrolled.The incidence of BPD was 45.7%.The smaller the gestational age and weight, the higher the incidence of BPD( P<0.001). Compared with non BPD group, the average birth age, weight and cesarean section rate in BPD group were lower, and the incidence of male infants, small for gestational age and 5-minute apgar score≤7 were higher( P<0.01). In BPD group, the incidences of neonatal respiratory distress syndrome(NRDS), hemodynamically significant patent ductus arteriosus, retinopathy of prematurity, feeding intolerance, extrauterine growth restriction, grade Ⅲ~Ⅳ intracranial hemorrhage, anemia, early-onset and late-onset sepsis, nosocomial infection, parenteral nutrition-associated cholestasis were higher( P<0.05), the use of pulmonary surfactant(PS), postnatal hormone exposure, anemia and blood transfusion were also higher, and the time of invasive and non-invasive mechanical ventilation, oxygen use and total hospital stay were longer( P<0.001). The time of starting enteral nutrition, cumulative fasting days, days of reaching total enteral nutrition, days of continuous parenteral nutrition, days of reaching 110 kcal/(kg·d) total calorie, days of reaching 110 kcal/(kg·d) oral calorie were longer and the breastfeeding rate was lower in BPD group than those in non BPD group( P<0.001). The cumulative doses of amino acid and fat emulsion during the first week of hospitalization were higher in BPD group( P<0.001). Multivariate Logistic regression analysis showed that NRDS, invasive mechanical ventilation, age of reaching total enteral nutrition, anemia and blood transfusion were the independent risk factors for BPD in VPI, and older gestational age was the protective factor for BPD. Conclusion:Strengthening perinatal management, avoiding premature delivery and severe NRDS, shortening the time of invasive mechanical ventilation, paying attention to enteral nutrition management, reaching whole intestinal feeding as soon as possible, and strictly mastering the indications of blood transfusion are very important to reduce the incidence of BPD in VPI.

Objective:To characterize the histopathological subtypes and their clinicopathological parameters of gender and onset age by common, rare and sparse primary esophageal malignant tumors (PEMT).Methods:A total of 272 437 patients with PEMT were enrolled in this study, and all of the patients were received radical surgery. The clinicopathological information of the patients was obtained from the database established by the State Key Laboratory of Esophageal Cancer Prevention & Treatment from September 1973 to December 2020, which included the clinical treatment, pathological diagnosis and follow-up information of esophagus and gastric cardia cancers. All patients were diagnosed and classified by the criteria of esophageal tumor histopathological diagnosis and classification (2019) of the World Health Organization (WHO). The esophageal tumors, which were not included in the WHO classification, were analyzed separately according to the postoperative pathological diagnosis. The χ 2 test was performed by the SPSS 25.0 software on count data, and the test standard α=0.05. Results:A total of 32 histopathological types were identified in the enrolled PEMT patients, of which 10 subtypes were not included in the WHO classification. According to the frequency, PEMT were divided into common (esophageal squamous cell carcinoma, ESCC, accounting for 97.1%), rare (esophageal adenocarcinoma, EAC, accounting for 2.3%) and sparse (mainly esophageal small cell carcinoma, malignant melanoma, etc., accounting for 0.6%). All the common, rare, and sparse types occurred predominantly in male patients, and the gender difference of rare type was most significant (EAC, male∶ female, 2.67∶1), followed with common type (ESCC, male∶ female, 1.78∶1) and sparse type (male∶ female, 1.71∶1). The common type (ESCC) mainly occurred in the middle thoracic segment (65.2%), while the rare type (EAC) mainly occurred in the lower thoracic segment (56.8%). Among the sparse type, malignant melanoma and malignant fibrous histiocytoma were both predominantly located in the lower thoracic segment (51.7%, 66.7%), and the others were mainly in the middle thoracic segment.Conclusion:ESCC is the most common type among the 32 histopathological types of PEMT, followed by EAC as the rare type, and esophageal small cell carcinoma and malignant melanoma as the major sparse type, and all of which are mainly occur in male patients. The common type of ESCC mainly occur in the middle thoracic segment, while the rare type of EAC mainly in the lower thoracic segment. The mainly sparse type of malignant melanoma and malignant fibrous histiocytoma predominately occur in the lower thoracic segment, and the remaining sparse types mainly occur in the middle thoracic segment.

Objective:To compare the values of medical image technologies in evaluating the tansperineal laser ablation (TPLA) in canine prostate.Methods:TPLA (3 W/600 J and 3 W/1 200 J) were operated in the prostate of six adult male beagles guided by transrectal ultrasound (TRUS). TRUS, transrectal contrast-enhanced ultrasound (TR-CEUS) and multiparameter magnetic resonance imaging (mpMRI) were used to evaluate the ablation on the day of TPLA, one week and one month after TPLA. The animals were sacrificed for pathology to calculate the volume of the ablation. SPSS 22.0 software was used for statistical analysis.Results:TRUS could be used to guide and observe the puncture and ablation process during TPLA. TR-CEUS and contrast enhanced MRI showed good consistency in the volume of ablation ( P>0.05). One month after TPLA, the ablation volume were (1.69±0.51)ml vs (1.73±0.36)ml vs (1.52±0.41)ml (3 W/600 J) and (2.23±0.54)ml vs (2.34±0.29)ml vs (2.19±0.34)ml (3 W/1 200 J) measured by the two medical image technologies and pathology, with good consistency ( P>0.05). Conclusions:TRUS can be used to guide and observe the puncture and ablation process during TPLA. TR-CEUS and mpMRI can be used for postoperative evaluation and follow-up of TPLA. The former has advantages of real-time and low price, which can be promoted and applied in clinical practice.
