Huopo Xialingtang is a famous classical formula for treating dampness and warmth， which is included in the Catalogue of Ancient Famous Classical Formulas（The First Batch）. In this paper， bibliometric methods was used to collect the literature related to Huopo Xialingtang， and 16 items of related literature were retrieved， involving five medical books， which were used to textual research on the origin， name， composition， drug dosage， preparation method， processing and main treatment symptoms of this formula. The results indicated that Huopo Xialingtang was originated from Yiyuan written by Shi Funan in the Qing dynasty， and and was later named and extended by He Lianchen. The composition of the proposed formula was consistent with the record of Yiyuan， and the origin of each Chinese materia medica was basically clear. Houpo was the dried bark and root bark of Magnolia officinalis， Zexie was the dried tubers of Alisma orientale， Kuxingren was the dried mature seeds of Prunus armeniaca， Doukou was the dried mature fruits of Amomum kravanh， the origin of Tuhuoxiang was consistent with the 2018 edition of Shanghai Standards of Processing Chinese Crud Drugs， and the origins of the remaining Chinese medicines were consistent with the 2020 edition of Chinese Pharmacopoeia. The converted dose of each Chinese medicine was 7.46 g for Agastache rugosa， 3.73 g for Magnoliae Officinalis Cortex， 8.39 g for Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine， 11.19 g for Poria， 11.19 g for Armeniacae Semen Amarum， 14.92 g for Coicis Semen， 2.61 g for Amomi Fructus Rotundus， 5.60 g for Polyporus， 5.60 g for Alismatis Rhizoma， 14.92 g for Tetrapanacis Medulla. Huopo Xialingtang was initially used for the treatment of dampness and warmth at the beginning of the disease， and was later expanded to treat dampness obstruction， dampness-warming dysentery and so on， but always with the dampness-heat in the lungs and spleen as the pathogenesis. In modern times， the clinical application is more extensive， used in digestive， respiratory， endocrine， nervous system and other types of diseases， especially for chronic gastritis， stomach pain and fever. By combing the ancient literature of Huopo Xialingtang， we verified the origin of the formula and determined the key information of the prescription， which can provide literature reference for the clinical application and drug development of this formula.

By consulting ancient and modern literature， the herbal textual research of Farfarae Flos has been conducted to verify the name， origin， producing area， quality evaluation， harvesting and processing methods， so as to provide reference for the development and utilization of the famous classical formulas containing Farfarae Flos. According to the research， the results showed that Farfarae Flos was first described as a medicinal material by the name of Kuandonghua in Shennong Bencaojing（《神农本草经》）， and the name was used and justified by later generations. The main origin was the folwer buds of Tussilago farfara， in addition， the flower buds of Petasites japonicus were used as medicine in ancient times. The ancient harvesting time of Farfarae Flos was mostly in the twelfth month of the lunar calendar， and the modern harvesting time is in December or before the ground freeze when the flower buds have not been excavated. Hebei， Gansu， Shaanxi are the authentic producing areas with the good quality products. Since modern times， its quality is summarized as big， fat， purple-red color， no pedicel is better. Processing method from soaking with licorice water in the Northern and Southern dynasties to stir-frying with honey water followed by micro-fire in the Ming dynasty， and gradually evolved to the modern mainstream processing method of honey processing. Based on the research results， it is suggested that the dried flower buds of T. farfara， a Compositae plant， should be selected for the development of famous classical formulas containing Farfarae Flos， and the corresponding processed products should be selected according to the specific processing requirements of the formulas， and raw products are recommended for medicinal use without indicating processing requirements.

Objective:To investigate the clinicopathological features and genetic characteristics of congenital cystic adenomatoid malformation (CCAM) of lung and CCAM associated lung cancer in adults.Methods:A total of 13 cases of CCAM of lung in adults, diagnosed from June 2015 to May 2023, were collected from the Department of Pathology, Shanghai Pulmonary Hospital, Tongji University School of Medicine, China. Their histopathological features were correlated with probable development into lung cancer. Next-generation sequencing was performed on the benign and malignant areas of all cases.Results:The pathological classification of all cases were of CCAM of lung type 1. There were 4 male and 9 female cases, age ranged from 18 to 65 years, with a mean age of 41 years. Six cases were accompanied by lung cancer, all of them were mucinous adenocarcinoma. Next-generation sequencing showed no gene mutation in 2 of the 13 cases; KRAS mutations in exon 2 were detected in 7 cases, in which there were 6 cases complicated with lung mucinous adenocarcinoma and no matter in the malignant or benign regions, the same case exhibited the same mutation sites in KRAS gene.Conclusions:CCAM of the lung is a congenital disease, and in adults, type 1 is most commonly found in the pathological classification, and it is often accompanied by cancer. Gene mutations are frequently detected in CCAM of the lung, KRAS being the most recurrent mutation which may play an important role in the carcinogenesis.

OBJECTIVE To explore the expression of trefoil factor family peptide(TFF3)in chronic rhinosinusitis with nasal polyps(CRSwNP)and its regulation on mucin 5AC(MUC5AC)expression.METHODS The nasal polyp tissues of 16 patients in the CRSwNP group and the nasal mucosal tissues of 16 patients in the control group were selected,and the expressions of TFF3 and MUC5AC were detected by quantitative real-time polymerase chain reaction(RT-qPCR)and Western blot,and the correlation between them was analyzed.The human nasal epithelial cell(HNEpC)line with TFF3 knockdown was constructed,and the expression of MUC5AC in KD-TFF3 HNEpC was detected by RT-qPCR and immunofluorescence.RESULTS The expression level of TFF3 in nasal polyps was significantly lower than that of control group,and the expression level of MUC5AC was increased,and the expression level of both was negatively correlated(r=-0.556,P<0.05).The expression of MUC5AC in KD-TFF3 HNEpC was significantly higher than that in control group.CONCLUSION The expression of TFF3 decreases in CRSwNP and negatively regulates the expression of MUC5AC.This study provides a new idea for the treatment of abnormal hypersecretion of mucous in chronic nasal inflammatory diseases represented by CRSwNP.

Through reviewing ancient and modern literature， the textual research of Anemarrhenae Rhizoma（AR） has been conducted to verify the name， origin， changes in production areas， quality evaluation， harvesting and processing methods， so as to provide reference for the development and utilization of the famous classical formulas containing AR. Through the herbal textual research， AR was first published in Shennong Bencaojing， and has been used as the proper name for this herb for generations， and the mainstream source of AR used for generations is the rhizome of Anemarrhena asphodeloides. The high-quality production areas that have been revered throughout the ages are Hebei， Shanxi， Shaanxi， Inner Mongolia and Fangshan district of Beijing， etc. In recent times， AR produced in Yixian county of Hebei province（Xiling Zhimu）， is better known and is regarded as a very good source. At present， cultivated AR is mainly produced in Yixian county and Anguo of Hebei province， Bozhou of Anhui province and other places. The medicinal parts of AR in ancient and modern times are all rhizomes， and the quality is better if it has thick flesh， hard wood， yellow outer color and white section color. The harvesting time recorded in ancient medical books is usually in lunar February and August， with exposure to dryness， while modern harvesting is spring and autumn. The processing methods of the past dynasties were mainly to remove the hair when using， avoid iron when cutting， process with wine or salt water， while the two main specifications in modern times are raw and salted products. Based on the systematic research， it is recommended that the dried rhizome of A. asphodeloides in the famous classical formulas be used for AR. If the original formula specifies processing requirements， it should be operated according to the requirements， if the processing requirements are not indicated， the raw products can be used as medicine.

Objective    To compare the clinical effects of segmentectomy and lobectomy for ≤2 cm lung adenocarcinoma with micropapillary and solid subtype negative by intraoperative frozen sections. Methods    The patients with adenocarcinoma who received segmentectomy or lobectomy in multicenter from June 2020 to March 2021 were included. They were divided into two groups according to a random number table, including a segmentectomy group (n=119, 44 males and 75 females with an average age of 56.6±8.9 years) and a lobectomy group (n=115, 43 males and 72 females with an average of 56.2±9.5 years). The clinical data of the patients were analyzed. Results    There was no significant difference in the baseline data between the two groups (P>0.05). No perioperative death was found. There was no statistical difference in the operation time (111.2±30.0 min vs. 107.3±34.3 min), blood loss (54.2±83.5 mL vs. 40.0±16.4 mL), drainage duration (2.8±0.6 d vs. 2.6±0.6 d), hospital stay time (3.9±2.3 d vs. 3.7±1.1 d) or pathology staging (P>0.05) between the two groups. The postoperative pulmonary function analysis revealed that the mean decreased values of forced vital capacity and forced expiratory volume in one second percent predicted in the segmentectomy group were significantly better than those in the lobectomy group (0.2±0.3 L vs. 0.4±0.3 L, P=0.005; 0.3%±8.1% vs. 2.9%±7.4%, P=0.041). Conclusion    Segmentectomy is effective in protecting lungs function, which is expected to improve life quality of patients.

Objective:To explore the application of a 3D printed patient-specific guider (3D-PSG) in complex total knee arthroplasty (TKA).Methods:A retrospective analysis was performed of the data of 44 patients who had received complex artificial TKA for articular and extra-articular deformities of the knee from January 2016 to October 2019 at Department of Orthopaedic Surgery, Nanjing First Hospital. According to whether a 3D-PSG had been applied, the patients were divided into 2 groups. In the 3D-PSG group of 23 patients, there were 11 males and 12 females, with an age of 63.7 years ± 10.2 years (from 53 to 81 years); in the conventional group of 21 cases, there were 10 males and 11 females, with an age of 64.2 years ±12.1 years (from 51 to 79 years). In the 3D-PSG group, the preoperative CT data were 3D reconstructed for measurement of a full lower limb and design of a 3D-PSG and TKA was assisted by a 3D-PSG which had been manufactured by a 3D printer using the STL files of the 3D-PSG imported. In the conventional group TKA was performed in a standard manner. In the 3D-PSG group, the TKA surgical parameters in the preoperative plan were compared with actual surgical measurements. The 2 groups were compared in terms of operation time, intraoperative blood loss, postoperative drainage volume, length of hospital stay, visual analogue scale (VAS), Knee Society Score (KSS), hip knee ankle (HKA), frontal femoral component (FFC), frontal tibial component (FTC), lateral femoral flexion (LFF) and lateral tibial component (LTC).Results:There were no significant differences between the 2 groups in the preoperative general data, showing comparability ( P>0.05). In the 3D-PSG group, no significant differences were found between preoperative parameters designed and actual intraoperative measurements in the prosthetic type of femoral condyle (3.4±1.1 versus 3.5±0.9) or of tibial plateau (3.1±0.9 versus 3.3±1.2), or in the filler thickness (10.6 mm ± 3.2 mm versus 10.9 mm ± 4.7 mm) ( P>0.05). The 44 patients were followed up for an average of 10.8 months (from 7 to 13 months). The 3D-PSG group had significantly less operation time (65.7 min ± 10.5 min), intraoperative blood loss (19.8 mL ±7.3 mL), postoperative drainage volume (124.6 mL ± 27.9 mL) and hospital stay (7.3 d ± 2.5 d) than the conventional group (82.4 min ± 11.7 min, 86.5 mL ± 35.7 mL, 154.6 mL ± 21.3 mL and 10.6 d ± 3.1 d) ( P<0.05). The VAS and KSS scores at postoperative day 1, week 1 and week 2 in the 3D-PSG group were significantly better than those in the conventional group ( P<0.05). Significantly more patients in the 3D-PSG group achieved approximately ideal values in HKA, FFC, FTC, LFF and LTC than those in the conventional group ( P<0.05). Conclusion:A 3D printed patient-specific guider may improve surgical accuracy, reduce operation time and achieve better surgical outcomes in complex total knee arthroplasty.

Objective:To investigate the clinical pathological features of primary pulmonary and tracheal glomus tumors.Methods:The clinical and pathological features of 11 cases (4 cases from Shanghai Pulmonary Hospital, Tongji University School of Medicine, China and 7 cases from Fudan University Shanghai Cancer Center, China) of respiratory glomus tumor diagnosed from 2010 to 2019 were analyzed, and reviewed in light of the relevant literature.Results:In the 11 cases, there were 5 males and 6 females, with the onset ages of 29?66 years (median age of 43). Six tumors were located in the lung, and 5 in the trachea. The tumor diameters ranged 1.0?7.5 cm, with the average diameter of 2.6 cm. At low magnification, the tumors were diffuse or lobulated in shape. The tumor cells composed of sheets of oval to short spindle cells, with sharply defined cell border and prominent branching thin-walled vessels. Among the 4 benign glomus tumors, one was classified as benign symplastic glomus tumor owing to the hyperchromatic or degeneration nuclei. Two cases were classified as glomus tumors of uncertain malignant potential, on the account of cellular atypia and rare atypical mitotic figures. Five cases were classified as malignant glomus tumors, owing to the tumor necrosis, vascular invasion, marked nuclear atypia, prominent nucleoli and brisk mitoses (2-20/10HPF) including pathological mitotic figures. The tumor cells showed strong immunostaining for SMA, vimentin, type Ⅳ collagen and caldesmon to different extents, while CD34, cytokeratin and S-100 stains were negative. One of the cases was positive for desmin, and one case positive for synaptophysin. Follow-up information was available in 8 patients with the duration ranging from 6 to 95 months. At the end of the follow-up, 6 patients were alive without recurrence or metastasis, and two of the patients with malignant glomus tumors died.Conclusions:Primary pulmonary and tracheal glomus tumors is rare. Among the reported cases, malignant glomus tumor is the most frequent, followed by benign glomus tumors and uncertain malignant potential glomus tumors. Glomus tumors show sheet-like growth pattern and clusters of round epithelioid cells with numerous vascular spaces. They can be easily misdiagnosed as carcinoid tumor. The final diagnosis should be combined with immunohistochemical staining, such as SMA, caldesmon and vimentin.

Objective: To establish an animal model of hard metal lung disease (HMLD) in rats, and to screen the indications for diagnosis of HMLD. Methods: The rats were randomly divided into 5 groups, each group included 8 rats: saline group, pure cobalt group, pure tungsten carbide group, silica group and hard metal (HM) group. 10 mg subjects were administered in each group by using the pulmonary endotracheal tube. After 8 week, the lung CT scan and lung tissue pathology were observed, the serum and bronchoalveolar lavage fluid (BALF) were collected for KL-6, TGF-beta1 and TGF-beta2. Results: The lung tissue structure of HM group was destroyed, a large number of nuclear giant cells and epithelial like cells appeared in the stroma, and uncommon CT scan images appeared in the lung. KL-6, TGF-beta1, TGF-beta2 expression in each group was not the same, the difference was statistically significant (P<0.05) . The expression of KL-6 and TGF-beta1 in serum was not identical in all the groups, the difference was statistically significant (P<0.05) . The expression of TGF-beta2 had no significant difference between the groups (P>0.05) . Conclusion Rats can be successfully established HMLD model, rats in vivo lung CT scan images appear abnormal, which are provided with assistant diagnostic value for HMLD. The expression of KL-6 and TGF-beta2 in serum and BALF on HMLD rats are not highly specific, and TGF-beta1 has reference value in the rat HMLD auxiliary diagnosis.
