Shengma Gegentang is one of the classic formulas in the Catalogue of Ancient Classic Prescriptions （Second Batch）. This study reviewed ancient and modern literature and used literature tracing and bibliometric methods to analyze the historical evolution， efficacy， indications， dosage decoctions， and modern clinical disease spectrum of Shengma Gegentang. The results indicated that the earliest record of Shengma Gegentang can be found in the Taiping Huimin Heji Jufang of the Song dynasty， but its origin can be traced back to the Shaoyao Siwu Jiejitang in the Beiji Qianjin Yaofang of the Tang dynasty. The composition dosage of Shengma Gegentang is 413 g of Cimicifugae Rhizoma， 619.5 g of Puerariae Lobatae Radix， 413 g of Paeoniae Radix Alba， and 413 g of Glycyrrhizae Radix et Rhizoma， which are ground into coarse powder. Each dose is 12.39 g， and the amount of water added is 300 mL. 100 mL of solution is decocted and taken at the right time. The four drugs in the formula play the role of relieving exterior syndrome， penetrating pathogenic factors， and detoxicating together. Its indications are widely involved in internal medicine， pediatrics， surgery， ophthalmology and otorhinolaryngology， obstetrics and gynecology， sexually transmitted diseases， and other diseases， such as measles， sores， acne， spots， surgical gangrene， red eyes， toothache， chancre， and fetal poison. The epidemic diseases treated by Shengma Gegentang are complicated， including rash， pox， macula， numbness， summer diarrhea， dysentery， sha disease， febrile symptoms， spring warmth， winter warmth， and cold pestilence. At the same time， it is a plague prevention formula. Although Shengma Gegentang has a wide range of indications， it cannot be separated from the pathogenic mechanism of evil Qi blocking the muscle surface and heat in the lungs and stomach. The modern clinical disease spectrum of Shengma Gegentang involves the ophthalmology and otorhinolaryngology system， nervous system， pediatric-related diseases and syndromes， skin system， hepatobiliary system， and digestive system. It plays a key role in the treatment of epidemic diseases such as measles， chronic hepatitis B， dysentery， and tetanus.

As a chronic metabolic disease,type 2 diabetes poses a significant threat to human health with increasing incidence.An increasing number of studies confirm that the pathogenesis of diabetes is closely related with alterations in multiple cellular signaling pathways.Although numerous studies have reported that traditional Chinese medicine compounds prevent diabetes by modulating cell signaling pathways,asystematic review of the mechanism of action of traditional Chinese medicine compounds in modulating cell signaling pathways is still lacking.Therefore,this paper summarizes the research of type 2 diabetes prevention and treatment,which was found mainly related to the signaling pathways such as PI3K/AKT,AMPK,MAPK,NF-κB,PPAR,TGF-β.This family of signaling pathways can treat type 2 diabetes by inhibiting pancreatic islet cell apoptosis,protecting pancreatic β-cell function,ameliorating insulin resistance,inhibiting hepatic gluconeogenesis,promoting glycogen synthesis,attenuating inflammation,and resisting oxidative stress.At the same time,we analyze the problems in current research and the future development trend,in order to provide a scientific theoretical basis for the drug development and clinical application of traditional Chinese medicine compound in the prevention and treatment of diabetes.

Qingyan Dropping Pills have the effects of relieving wind and heat, detoxifying, and promoting the pharynx. It is commonly used in traditional Chinese medicines to treat acute and chronic pharyngitis, as well as sore throats and dry throats caused by surgery. Recently, many studies have shown that Qingyan Dropping Pills have certain effects on bacteriostasis, anti-inflammatory, antioxidant, and antiviral activities. As the coronavirus disease 2019 (COVID-19) pandemic enters the post-epidemic era, the regular use of drugs for COVID-19 pandemic symptoms has become a new trend. Therefore, there is a good market prospect to explore and develop Chinese patent medicines with antiviral effects. A preliminary study on the herbal formula and material basis of Qingyan Dropping Pills revealed that they have potential for antiviral applications. In this paper, the research on the quality study and antiviral effect of Qingyan Dropping Pills was reviewed, and the research direction of its secondary development was discussed to provide ideas and references for the new use of old traditional Chinese medicines.

Clinical data of 210 patients with early colorectal cancer and precancerous lesion treated by endoscopic submucosal dissection (ESD) in the Digestive Endoscopy Center of the Seventh Medical Center of Chinese PLA General Hospital from January 2015 to March 2018 were collected and analyzed retrospectively. Patients were divided into two groups according to the age: the elderly group (≥65 years old, 100 cases) and the non-elderly group (<65 years old, 110 cases). The en bloc resection rate, complete resection rate,and curative resection rate of the elderly group were 92.0% (92/100), 91.0% (91/100) and 89.0% (89/100), respectively. The above indicators of the non-elderly group were 90.9% (100/110) ( P=0.972), 90.0% (99/110) ( P=0.991) and 88.2% (97/110) ( P=1.000), respectively. The incidence of intraoperative perforation in the elderly group was 4.0% (4/100) and in the non-elderly group was 6.4% (7/110) ( P=0.543). Delayed postoperative bleeding rate was 2.0% (2/100) in the elderly group, and 0 (0/110) in the non-elderly group ( P=0.226). ESD is effective and safe in treating early colorectal cancer and precancerous lesion in elderly patients.

Objective:To explore the application value of two-dimensional speckle tracking imaging (2D-STI) in evaluating diaphragm function, and to compare the ability of 2D-STI and conventional diaphragm ultrasonography in diagnosing diaphragmatic dysfunction and evaluating disease severity in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD).Methods:A total of 58 AECOPD patients admitted to the First Affiliated Hospital of Xi′an Jiaotong University from January to October 2021 were retrospectively enrolled as AECOPD group, and 34 healthy subjects were recruited as control group during the same period. Repeatability test of diaphragmatic 2D-STI was performed. According to modified Medical Research Council (mMRC) dyspnea scores system and COPD Assessment Test (CAT), mMRC 0-1 and CAT<10 was classified as group A, mMRC≥2 and CAT≥10 was classified as group B. The baseline characteristics, conventional diaphragm ultrasonography parameters(thickening fraction and excursion) and 2D-STI parameters (longitudinal and radial strains) were compared between the AECOPD group and the control group, and the Spearman correlation between parameters of AECOPD group and forced expiratory volume in one second (FEV1) was analyzed. The differences of these parameters between group A and B were also compared. The ROC curve of conventional diaphragm ultrasonography parameters and 2D-STI parameters was plotted to differentiate group A from group B, and the diagnostic efficacy was evaluated.Results:Great intra- and inter-observer reproducibility was found for all diaphragmatic 2D-STI parameters, with ICCs above 0.80 for all measurements. The control group and the AECOPD group did not differ in age, sex and body mass index( P>0.05), whereas there were significant differences in smoking history, lung function, bilateral thickening fraction, excursion, longitudinal and radial strains( P<0.05). Compared with control group, patients in group A had a significant increase in diaphragm thickness ( P<0.05), while there was no significant difference in that between group B and control group ( P>0.05). The bilateral longitudinal strains, radial strains and thickening fraction of diaphragm were linearly correlated with FEV1 (right side rs=0.828, 0.794, 0.843, respectively; all P<0.001; left side rs=0.757, 0.704, 0.752, respectively; all P<0.001 ), while the correlation between excursion and FEV1 was not significant(right side rs=0.247, left side rs=0.253; all P>0.05). There were significant differences in bilateral longitudinal strains, radial strains and thickening fraction between group A and group B(all P<0.05), whereas there was no significant difference in excursion between the two groups ( P>0.05). ROC analysis showed bilateral longitudinal and radial strains had higher accuracy in distinguishing group A from group B than thickening fraction and excursion(right side AUCs 0.90, 0.84, 0.78 and 0.62, respectively; left side AUCs 0.85, 0.83, 0.77 and 0.62, respectively). Conclusions:2D-STI is a real-time noninvasive technique for diaphragm function assessment, which has high clinical value. Compared with conventional ultrasonography, 2D-STI shows more accuracy and effectiveness in diagnosing diaphragmatic dysfunction and evaluating disease severity of patients with AECOPD.

Immune checkpoints are the crucial regulators of immune system and play essential roles in maintaining self-tolerance, preventing autoimmune responses, and minimizing tissue damage by regulating the duration and intensity of the immune response. Furthermore, immune checkpoints are usually overexpressed in cancer cells or noninvasive cells in tumor tissues and are capable of suppressing the antitumor response. Based on substantial physiological analyses as well as preclinical and clinical studies, checkpoint molecules have been evaluated as potential therapeutic targets for the treatment of multiple types of cancers. In the last few years, extensive evidence has supported the immunoregulatory effects of traditional Chinese medicines (TCMs). The main advantage of TCMs and natural medicine is that they usually contain multiple active components, which can act on multiple targets at the same time, resulting in additive or synergistic effects. The strong immune regulation function of traditional Chinese medicine on immune checkpoints has also been of great interest. For example,

Objective: To explore the application of septoplasty and cheiloplasty in complete unilateral cleft lip repairment, and evaluate the effect on nasal shape correction. Methods: Twenty-four infants with complete unilateral cleft lip were divided into two groups: the correction group and the control group. Both groups underwent cheiloplasty by Mohler′s technique, septoplasty was performed in the correction group during the primary cheiloplasty. Six-month follow-up was taken to evaluate the nasal shape with the three dimensional images. Independent-samples t Test was performed using SPSS 21.0, to compare the nasal morphology between two groups. Results: All patients healed in the first stage, and were followed for 6 months after operations. There were no complication, including nasal septum perforation, occurred in either group.There were statistically significant differences in nasal parameters between the correction group and controls (P<0.05). The columellar width, nostril width on the affected side, and columella deviation of the correction group were smaller, than those of controls. The nose tip height, columellar height and nostril height on the affected side of the correction group were greater than those of the control group. Conclusions Septoplasty associated with the primary cheiloplasty in complete unilateral cleft lip repairment, shows better results in the elongation of the nasal columella, and the correction of septum deviation, and provides a stable nasal structure.

Objective To describe the status quo of readiness for hospital discharge of liver cancer patients accepted transcatheter arterial chemoembolization(TACE)treatment and to explore its influencing factors. Methods A cross-sectional survey was conducted. A self-designed general information questionnaire and the Readiness for Hospital Discharge Scale were delivered to 113 liver cancer patients accepted TACE from the Second Hospital of Dalian Medical University. Results The score of readiness for hospital discharge of liver cancer patients accepted TACE treatment was(171.73±14.71)points,and each item was divided into (7.81±0.67) points. Multiple linear regression analysis showed that age and education level were important factors influencing the degree of readiness for hospital discharge(t=-5.591,5.982,P<0.05). Conclusions The level of readiness for hospital discharge of liver cancer patients accepted TACE treatment is relatively satisfactory. Medical staff should provide targeted health education and intervention measures to improve their discharge readiness and ensure their safety after discharge.

Objective To evaluate the clinical efficacy of pre-procedure simethicone on detection of pharynx by upper gastrointestinal endoscopy. Methods A total of 100 patients with esophageal squamous cell carcinomas ( ESCCs) were enrolled in this prospective controlled trial and randomly assigned into two groups. The study group was given gargle with 5 mL simethicone plus 5 mL water combined with conventional procedure before gastroscopy. The control group was prepared according to the conventional procedure. The age, gender, tumor stage, lesion size, doctor＇s satisfaction and examination time between two groups were analyzed. Results The basic conditions between the two groups, including age, gender, and tumor stage were not significantly different (all P＞0. 05). The detection rate of superficial lesion in pharynx was higher in the study group than that in the control group, with no significant difference [8. 16%(4/49) VS 2. 04%( 1/49), P＝0. 362]. The median time of pharyngeal observation in the study group was less than that in the control group (21. 7 s VS 33. 9 s, P＝0. 000). The doctor was more satisfied in the study group than the control group (P＝0. 001). Conclusion Pre-procedure with simethicone improves the endoscopic visibility and detection rate of superficial squamous cell carcinoma with less observation time.

Objective To investigate the expression of endothelial protein C receptor (EPCR) and its roles in plasma and placenta of patients with early onset severe preeclampsia. Methods Sixty cases of severe preeclampsia women who delivered in Xuzhou Maternity and Child Health Care Hospital from March 2014 to February 2016, were recruited, which included 30 cases with early onset severe preeclampsia (early onset group, gestational week <34 weeks ) and 30 patients with late onset severe preeclampsia (late onset group, gestational week ≥34 weeks). Thirty cases of healthy late pregnant women at the same period (gestational week≥34 weeks) were selected as control group. Immunohistochemistry SP method was applied to detect the expression of in EPCR placenta. Reverse transcription (RT)-PCR was used to detect the expression of EPCR mRNA in placenta. ELISA method was used to detect the levels of soluble EPCR (sEPCR)level in plasma of the pregnant women of the three groups. Results The expression of EPCR in placenta mainly distributed in the membrane and cytoplasm of placental syncytiotrophoblasts and vascular endothelial cells, a few in the cell nucleus. The expression of EPCR in early onset group(57%, 17/30)was significantly lower than that in late onset group (93%, 28/30; χ2=25.165,P=0.001). The expression of EPCR in late onset group had no significant difference from that in control group (97%, 29/30;χ2=0.540,P=0.910). The expression of EPCR mRNA in placenta of early onset group(0.40±0.07)was significantly lower than that in late onset group(0.91±0.06;t=-30.044,P=0.001), while there was no statistical difference of the expression of EPCR mRNA between the late onset group and the control group (0.92±0.07;t=-0.631, P=0.538). Plasma sEPCR level in early onset group, late onset group and control group were (231 ± 11), (124±6)and(121±4)μg/L respectively, which is higher in early onset group than that in late onset group (t=48.080,P=0.001). There was no statistical difference of plasma sEPCR level between the late onset group and the control group(t=2.534,P=0.100). Conclusions The pathogenesis of early onset and late onset severe preeclampsia may be different. Decreased expression of EPCR in placenta may be associated with the pathogenesis of early onset severe preeclampsia.
