Through data collection and collation combined with bibliometrics， this study conducted a series of textual research on Yanghetang， such as the name and origin， the evolution of prescription composition and modern clinical application. Yanghetang was first recorded in Bencao Yidu of WANG Ang in the Qing dynasty. In addition to Yanghetang， there were 3 bynames of Jiawei Yanghetang， Quanshengji Yanghetang and Zhenjun Yanghetang. Regarding the composition of the formula， a total of 4 versions of Yanghetang were collected. The first version is the 5 medicines version of Cervi Cornus Colla， Rehmanniae Radix Praeparata， Cinnamomi Cortex， Zingiberis Rhizoma and Ephedrae Herba in Bencao Yidu. The second version is the 7 medicines version of Waike Zhengzhi Quanshengji， changing Zingiberis Rhizoma to Zingiberis Rhizoma Praeparatum Carbonisata（ZRPC） and adding Sinapis Semen and Glycyrrhizae Radix et Rhizoma（GRR） on the basis of Bencao Yidu， and most of the Yanghetang is of this version. The third version is the 6 medicines version of Wushi Yifang Huibian， that is， on the basis of Bencao Yidu， Zingiberis Rhizoma is changed into ZRPC， and Sinapis Semen is added. The fourth version is the 6 medicines version in Yifang Jiedu， that is， on the basis of Bencao Yidu， Zingiberis Rhizoma is changed into Zingiberis Rhizoma Praeparatum， and GRR Praeparata cum Melle is added. Regarding the dose of Yanghetang， the doses of the medicines in Waike Zhengzhi Quanshengji was converted into the modern doses as follows：37.3 g of Rehmanniae Radix Praeparata， 1.87 g of Ephedrae Herba， 11.19 g of Cervi Cornus Colla， 7.46 g of Sinapis Semen， 3.73 g of Cinnamomi Cortex， 3.73 g of GRR， and 1.87 g of ZRPC. The origins of the above medicines are consistent with the 2020 edition of Chinese Pharmacopoeia. The processing specification of Rehmanniae Radix Praeparata is steaming method， ZRPC is ginger charcoal， Sinapis Semen is the fried products， and the rest of the medicines are raw products. The decoction method was verified by the decoction method in Chonglou Yuyao， which is similar in the time， and it is recommended that the above medicines should be added with 600 mL of water， decocted to 100 mL， and taken warmly 30 min after meal. For each dose， it is recommended to use 1-3 doses per day according to the doctor's advice in combination with clinical practice. The diseases involved in the ancient applications involved 42 diseases in 11 departments， including orthopedics， dermatology and gynecology， which were dominated by Yin-cold syndrome. However， the diseases involved in modern research also include 148 related diseases in 10 departments， such as orthopedics， obstetrics and gynecology， which is consistent with the ancient books. In recent years， the research hotspots of Yanghetang have focused on more than 10 fields， including osteoblasts， malignant tumors， wound healing， traditional Chinese medicine fumigation and so on， which are widely used. It is suitable for comprehensive research and development because of its rational formula composition， clear origin， processing and decoction method， and wide clinical application.

In this study， bibliometric methods were used to systematically investigate the name and origin， the evolution of prescription composition， dose evolution， origin and processing method， decoction method， ancient application， modified application， modern application and other information of Huoxiang Zhengqisan. After research， Huoxiang Zhengqisan， also known as Huoxiang Zhengqitang， was first recorded in Taiping Huimin Hejijufang. The original formula is composed of 41.3 g of Arecae Pericarpium， 41.3 g of Angelicae Dahuricae Radix， 41.3 g of Perilla frutescens（actually Perillae Folium）， 41.3 g of Poria， 82.6 g of Pinelliae Rhizoma， 82.6 g of Atractylodis Macrocephalae Rhizoma， 82.6 g of Citri Reticulatae Pericarpium（actually Citri Exocarpium Rubbum）， 82.6 g of Magnoliae Officinalis Cortex， 82.6 g of Platycodonis Radix， 123.9 g of Pogostemonis Herba， and 103.25 g of Glycyrrhizae Radix et Rhizoma. In this formula， Magnoliae Officinalis Cortex is processed according to the specifications for ginger-processed products， Glycyrrhizae Radix et Rhizoma is processed according to the specifications for stir-fried products， and other herbs are used in their raw products. The botanical sources of the herbs are consistent with the 2020 edition of Pharmacopoeia of the People's Republic of China. The above herbs are ground into a fine powder with a particle size passing through a No. 5 sieve. For each dose， take 8.26 g of the powdered formula， add 300 mL of water， along with 3 g of Zingiberis Rhizoma Recens and 3 g of Jujubae Fructus， and decoct until reduced to 140 mL. The decoction should be administered hot， with three times daily. To induce sweating， the patient should be kept warm under a quilt， and an additional dose should be prepared and taken if needed. This formula is traditionally used to relieve the exterior and resolve dampness， regulate Qi and harmonize the middle， which is mainly used to treat a series of diseases of digestive and respiratory systems. However， potential adverse reactions， including allergies， purpura and disulfiram-like reactions， should be considered during clinical use. Huoxiang Zhengqisan features a rational composition， extensive clinical application， and strong potential for further research and development.

Lianggesan was first recorded in Taiping Huimin Heji Jufang， which was composed of Rhei Radix et Rhizoma， Natrii Sulfas， Gardeniae Fructus， Forsythiae Fructus， Scutellariae Radix， Glycyrrhizae Radix et Rhizoma（GRR）， Menthae Haplocalycis Herba， Lophatheri Herba and Mel. It was clinically applied to treat fire-heat syndrome in the upper and middle Jiao， and the curative effect was positive. In this study， the bibliometric method was used to conduct a detailed textual research on the formula name， medicinal composition， dosage evolution， origin and processing， functional indications and other aspects of Lianggesan. Research revealed that Lianggesan has six other names， such as Lianqiao Yinzi， Lianqiao Jiedusan， Jufang Lianggesan， Jiegu Lianggesan， Hejian Lianggesan and Qingji Lianggesan. Based on the edition of Taiping Huimin Heji Jufang， an analysis of the evolution of its formula composition revealed that the missing Chinese medicines were predominantly bamboo leaves and honey， while the added Chinese medicines were primarily supplements introduced to address changes in disease manifestations. After textual research， the dosage for one dose of Lianggesan from Taiping Huimin Heji Jufang was as follows：826 g of Rhei Radix et Rhizoma， 826 g of Natrii Sulfas， 826 g of GRR， 413 g of Gardeniae Fructus， 413 g of Menthae Haplocalycis Herba， 413 g of Scutellariae Radix， and 1652 g of Forsythiae Fructus. Decocting method was as following：Grinding the Chinese medicines into coarse powder（2-4 mm）， taking 8.16 g per dose， adding 300 mL of water， along with 2 g of Lophatheri Herba and 5 g of Mel， and decocting to 140 mL. The residue was removed and taken warmly 30 min after meals. It was recommended to take it three times daily until improvement was achieved. The origins of the 9 Chinese medicines were consistent with the 2020 edition of Pharmacopoeia of the People's Republic of China. Except for GRR， which required single frying（stir-frying）， the remaining medicines were all raw products. The description of the function of this formula in ancient books was summarized as purging fire and promoting bowel movements， clearing heat from the upper body and purging the lower body， and the main syndromes included facial redness， tongue swelling， red eyes， etc. In modern applications， the formula is primarily used for respiratory and digestive system diseases， including acute lung injury， chronic obstructive pulmonary disease， herpetic angina and aphthous stomatitis， covering 142 types of diseases. In summary， this paper can provide a basis for further research and development of Lianggesan through the literature review and key information combing.

OBJECTIVES: To propose a hypothesis that aloe-emodin may inhibit scar tissue fibrosis through thrombospondin-1(THBS1)-PI3K-Akt pathway. METHODS: By cultivating fibroblasts derived from scar tissue after cleft palate surgery in humans, aloe emodin of different concentrations (10, 20, 30, 40 and 50 μmol/L) was added to the cells which activity was detected. At the same time, transcriptome sequencing was performed on scar tissue and cells, and bioinformatics methods were used to explore potential targets and signaling pathways of scar tissue fibrosis. RESULTS: Aloe-emodin had a concentration dependent inhibitory effect on fibroblast proliferation,with the 40 μmol/L concentration group showing the most significant effect. The results of tissue and cell sequencing indicated that differentially expressed genes were significantly enriched in extracellular matrix-receptor interaction pathway, and shared a common differential gene which was THBS1. The ORA analysis results indicated that differentially expressed genes, including THBS1, were significantly enriched in the PI3K-Akt signaling pathway. CONCLUSIONS Aloe emodin may inhibit the PI3K-Akt pathway by downregulating THBS1, thereby reducing the proliferation activity of fibroblasts derived from postoperative palatal scar tissue.

OBJECTIVE：To investigate the mechanism of sinapic acid （SA）against PC 12 cell injury induced by Amyloid β1-42 protein（Aβ1-42）based on PI 3K/Akt/GSK3β signaling pathway. METHODS：PC12 cells of rats were randomly divided into control group，Aβ group（Aβ1-42 2 μmol/L），Aβ+SA group（Aβ1-42 2 μmol/L+SA100 μmol/L），Aβ+SA+LY group [Aβ1-42 2 μmol/L+SA 100 μmol/L+LY294002（PI3K inhibitor ）10 μmol/L]，Aβ+LY group（Aβ1-42 2 μmol/L+LY294002 10 μmol/L）and LY group （LY294002 10 μmol/L）. Except for control group and LY group ，the cells of other groups were replicated the damage model with Aβ1-42. After 24 hours of culture ，the morphology of cells was obsened in each group with a microscope ，and MTT assay was adopted to determine the cell viability of PC 12 cells in each group. Western blotting assay was used to detect the expression of PI 3K，p-PI3K， Akt，p-Akt，GSK3β and p-GSK3β in cells of each group. RESULTS：Compared with control group ，the number of cells decreased and some synaptic breaks disappeared in Aβ group while cell viability，ratio of p-PI 3K/PI3K，p-Akt/Akt and p-GSK 3β/GSK3β in Aβ group were decreased significantly（P＜0.05 or P＜0.01）. Compared with Aβ group，the cells became round and synapses became more in Aβ+SA group while cell viability，the ratio of p-PI 3K/PI3K，p-Akt/Akt and p-GSK 3β/GSK3β were increased significantly（P＜0.05）. Compared with Aβ+SA group，some synaptic breaks occurred in Aβ+SA+LY group while cell viability， the ratio of p-PI 3K/PI3K，p-Akt/Akt and p-GSK 3β/GSK3β were decreased significantly（P＜0.05）；Aβ+LY group had more cell debris，and t he cell viability was decreased ，but the difference was not significant ，and the ratio of p-PI 3K/PI3K，p-Akt/Akt and p-GSK3 β/GSK3 β had no significant change （P＞0.05）; LY294002 alone had no significant effect on morphology ，cellviability and the ratio of p-PI 3K/PI3K，p-Akt/Akt or p-GSK 3β/ GSK3 β （P＞0.05）. CONCLUSIONS ： SA may play aprotective role against PC 12 cell injury induced by A β 1-42 through activating PI 3K/Akt/GSK-3β.

Objective: To investigate the clinical efficacy of combination therapy of selenium yeast and levothyroxine sodium in the treatment of type 2 diabetes mellitus complicated with chronic lymphocytic thyroiditis(CLT). Methods: A total of 96 patients with type 2 diabetes mellitus complicated with CLT who admitted to Wenling Hospital of Traditional Chinese Medicine from June 2017 to December 2018 were randomly divided into control group and treatment group according to the digital table, with 48 patients in each group.On the basis of stable blood sugar control, the control group received routine treatment with levothyroxine sodium tablets.The treatment group was given selenium yeast on the basis of the control group.The blood glucose, thyroid, clinical efficacy within 3 months of treatment were recorded. Results: The total effective rate of the study group was 95.83%(46/48), which was significantly higher than 68.75%(33/48) of the control group(χ²=12.080, P<0.05). The levels of blood sugar and glycosylated hemoglobin in the study group were significantly lower than those in the control group after treatment(all P<0.05), and the levels of C-peptide in the fasting and postprandial 2h were significantly higher than those in the control group(t=4.927-8.725, all P<0.05). After treatment, the serum selenium level in the study group was significantly higher than that in the control group(P<0.05), and the serum TPOAb and TGAb levels were significantly lower than those in the control group(t=17.264-27.032, all P<0.05). There were no statistically significant differences in serum TSH, FT₃ and FT₄ levels between the two groups(t=0.704-1.926, all P>0.05). Conclusion The clinical efficacy of selenium yeast and levothyroxine in the treatment of type 2 diabetes with CLT is significantly better than traditional treatment.

To analyze the incidence and imaging characteristics of pulmonary nodules in a unit staff.
 Methods: Low-dose spiral CT (LDCT) scan were performed in 1 372 staffs ≥45 years old in a certain unit during the physical examination. The clinical and imaging data were collected to analyze the detection rate, imaging characteristics, and postoperative pathological conditions of pulmonary nodules.
 Results: The total detection rate for pulmonary nodules was 30.39% (417/1 372). The detected nodules were mainly single (227 cases), solid (343 cases), <5 mm in diameter (261 cases), and Lung-Reporting and Data System (Lung-RADS) category 2 nodules (340 cases). The single nodules were mostly found in the right upper lung (74 cases, 32.60%). The detection rate of pulmonary nodules tended to decrease but the detection rate of category 4 nodules increased with the increasing age (P<0.05), while the gender had no significant influence on the detection rate (P>0.05). Compared with the Lung-RADS category 3 nodules, the proportions of nodules in subsolid state, with irregular shape, lobulation sign, and vascular penetration in the Lung-RADS category 4 were increased (all P<0.05). Among them, 11 patients received surgical therapy, including 10 women. Postoperative pathology confirmed lung adenocarcinoma in 9 patients (2.16%), including 8 women, all non-smokers.
 Conclusion: The nodules in subsolid state with vascular penetration, irregular shape and lobulation sign tend to be malignant. Lung cancer screening with low-dose spiral CT in female non-smokers should be emphasized.

MicroRNA-132 (miR-132), a small RNA that regulates gene expression, is known to promote neurogenesis in the embryonic nervous system and adult brain. Although exposure to psychoactive substances can increase miR-132 expression in cultured neural stem cells (NSCs) and the adult brain of rodents, little is known about its role in opioid addiction. So, we set out to determine the effect of miR-132 on differentiation of the NSCs and whether this effect is involved in opioid addiction using the rat morphine self-administration (MSA) model. We found that miR-132 overexpression enhanced the differentiation of NSCs in vivo and in vitro. Similarly, specific overexpression of miR-132 in NSCs of the adult hippocampal dentate gyrus (DG) during the acquisition stage of MSA potentiated morphine-seeking behavior. These findings indicate that miR-132 is involved in opioid addiction, probably by promoting the differentiation of NSCs in the adult DG.
