In this paper， the name， origin， producing area， harvesting， processing and functional indications of Arcae Concha were systematically combed and verified by consulting the ancient and modern literature， in order to provide a basis for the development of famous classical formulas containing Arcae Concha. Arcae Concha was first recorded in the name of Han in Bencao Shiyi， but later， due to the influence of LI Shizhen's error of combining Han item with Kuiha in the Ming dynasty， there were aliases such as Kuilu and Fulao， and Yizong Bidu began to include Walengzi as its correct name and has been used ever since. The textual descriptions and illustrations of the medicinal materials of Arcae Concha contained in the materia medica of the past generations were consistent with the modern Arca inflata， A. subcrenata and A. granosa. In ancient times， there were medicinal records of two parts of shell and meat， but now the shell is used as medicine， and the meat is mostly edible. In ancient times， Zhejiang， Shandong， Guangdong and Guangxi were the main producing areas， and Zhejiang was the best. It is now believed that A. inflata is mostly distributed in the northern part of the Huanghai Sea， A. granosa is mostly distributed in the coastal areas south of Shandong Peninsula in China， and A. subcrenata is widely distributed in the coastal areas of China. Its quality is better in a complete， white， no residual meat and sand. In ancient times， there was no clear harvesting period， and the processing was mainly based on vinegar quenching after calcination or powdering of calcined shell， but now the harvesting period is autumn and winter. After harvesting， it is directly washed and crushed for raw use or processed by calcined method. The records of the medicinal materials in the past dynasties on the properties of Arcae Concha were mainly warm， sweet， salty and mild， and it is now believed that Arcae Concha is salty in taste and mild in nature. In ancient times， it was believed that Arcae Concha were mainly used for coldness in the heart and abdomen， coldness in the waist and spine， benefiting the five internal organs， strengthening the stomach. Nowadays， it is believed that Arcae Concha can eliminate phlegm and remove blood stasis， soften the hardness and dissipate the lumps， produce acid and relieve pain. It can be used in the treatment of stubborn phlegm， gall tumor， scrofula and other symptoms. In conclusion， it is suggested that for the famous classical formulas containing Arcae Concha， the corresponding methods should be selected according to the processing requirements of the drug in the formulas， while those without processing requirements can be determined according to the functional position of the products.

Guided by Academician Zhang Boli's theory of "dampness， turbidity， phlegm， and fluid-related diseases"，this paper elaborated on the pathogenesis and syndrome differentiation treatment of heart failure from the perspective of the "spleen-mitochondria". It analyzed the essential similarities between "spleen-mitochondria" and "dampness， turbidity， phlegm， and fluid-related diseases"， as well as their close association with the onset of heart failure. Furthermore，it explored the connection between spleen function and mitochondrial function in traditional Chinese medicine （TCM），positing that the spleen's role in transportation and transformation is analogous to mitochondrial material metabolism and energy conversion，with spleen deficiency closely related to mitochondrial dysfunction. It thus concluded that mitochondrial material metabolism and energy conversion represent the microscopic essence of the spleen's role in transportation and transformation，and mitochondrial dysfunction is a contributing factor to pathological products like dampness and turbid phlegm，which are closely associated with the occurrence of heart failure. The four elements of dampness，turbidity，phlegm，and fluid are a series of related symptoms resulting from abnormal fluid transportation and transformation，serving as both factors in the onset of heart failure and the core pathological basis for its deterioration. Therefore，during the treatment of heart failure，it is essential to regulate mitochondrial function. Early intervention should focus on eliminating dampness and turbidity to improve mitochondrial function and restore normal energy metabolism. In the middle and late stages，emphasis should be placed on resolving phlegm，promoting blood circulation，warming Yang，and reducing water retention to alleviate mitochondrial damage and improve cardiac function. Supporting Qi and strengthening the spleen should be a continuous approach，and treatment should be adjusted to enhance mitochondrial function and stabilize the condition，thereby improving prognosis. This paper discussed the role of the spleen and mitochondria in the pathogenesis of heart failure，examined the evolution of heart failure mechanisms from the perspective of dampness， turbidity， phlegm， and fluid-related diseases，and proposed a phased treatment strategy. It enriched the theory of dampness， turbidity， phlegm， and fluid-related diseases and offered new strategies for heart failure treatment. However，in practical application，TCM strategies for treating heart failure need to be integrated with modern medical approaches to provide a more solid scientific foundation for treatment.

Diabetic cardiomyopathy （DCM）， a cardiovascular complication caused by diabetes mellitus， is a major cause of heart failure and even sudden cardiac death in diabetic patients. Traditional Chinese medicine （TCM） posits that the core pathogenesis of DCM lies in internal deficiency and superficial excess， characterized by deficiency of both Qi and Yin combined with phlegm and blood stasis. Modern medical treatments for DCM primarily focus on blood glucose control and symptom alleviation yet lack targeted therapeutic strategies. In contrast， TCM offers a wealth of practical experience and a complete theoretical system， demonstrating definite clinical efficacy and high medication safety in DCM management. As a classic formula for tonifying Qi and nourishing Yin， Shengmaisan comprises Ginseng Radix et Rhizoma， Ophiopogonis Radix， and Schisandrae Chinensis Fructus. It contains multiple bioactive components， including ginsenosides， ophiopogonin， schisandrins， and homoisoflavonoids， which exhibit cardioprotective properties. The therapeutic mechanisms of Shengmaisan-like formulae for DCM involve enhancing myocardial contractility， attenuating myocardial fibrosis， modulating mitochondrial quality control， regulating glucose metabolism， mitigating oxidative stress， and suppressing inflammatory responses. Clinically， Shengmaisan-like formulae not only manage hyperglycemic status but also ameliorate cardiac structural and functional impairments and enhance exercise tolerance in DCM patients， playing a vital role in the prevention， treatment， and rehabilitation of DCM. This paper analyzes the feasibility of Shengmaisan-like formulae in DCM management and synthesizes current research achievements regarding their chemical components， mechanisms of action， and clinical applications， aiming to provide a scientific foundation for the use of such formulae in the treatment of DCM.

It is found that acupuncture can significantly improve the clinical symptoms of rheumatoid arthritis (RA) such as pain and joint stiffness, and improve rheumatoid factor, high-sensitivity CRP, ESR and other clinical indicators. It can inhibit the proliferation of synovial cells, the apoptosis of chondrocytes, and regulate polarization balabce of mononuclear macrophages, T cells, as well as inhibit the inflammatory function of multiple immune cells, in order to improve inflammation state of RA joints. In clinical treatment of RA, bladder meridian, stomach meridian, spleen meridian , and Governor Vessel are mostly selected. Acupoints with the efficacy of warming meridian, dispelling coldness and dredging collaterals were commonly selected such as Zusanli (ST36), Yanglinquan (GB34), Dazhui (GV14), Quchi (LI11). Several researches have proved that combined therapy of acupuncture and medicine is worthy promotion in clinic.

Objective To explore the value of fractional order calculus(FROC)model diffusion weighted imaging(DWI)for evaluating pathological classification and differentiation degree of cervical cancer(CCA).Methods Totally 74 CCA patients were enrolled and divided into squamous cell carcinoma(SCC)group(n=54)and adenocarcinoma(ACA)group(n=20)based on pathological classification,also low differentiation group(n=33)and medium-high differentiation group(n=41)based on differentiation degree.Conventional MR examination and DWI with 12 b-values were performed,FROC model parameters(D,β,and p value)and the apparent diffusion coefficient(ADC)of mono-exponential model were obtained via software analysis.The parameters were compared between groups,and receiver operating characteristic curve of those being significantly different between groups were drawn,the area under the curves(AUC)were calculated to evaluate the diagnostic efficacy.Results Significant differences of ADC,D,and β values were found between SCC group and ACA group(all P＜0.05),and D value had the highest AUC(0.726)for distinguishing pathological classification CCA.Meanwhile,significant differences of D,β,p values and ADC were observed between low differentiation group and medium-high differentiation group(all P＜0.05),D value also had the highest AUC(0.865).AUC of the combined model constructed based on significant variables β and p values in logistic regression was 0.926,higher than that of each parameter alone(all P＜0.05).Conclusion FROC model DWI could be used to evaluate pathological classification and differentiation degree of CCA.

Objective To explore the effect of chlorophyll derivative on wound healing after hemorrhoidectomy. Methods A total of 124 patients with circular hemorrhoids after procedure for prolapse and hemorrhoids (PPH) were selected and divided into control group and experimental group. The granulation formation time, wound healing time, degree of wound edema and pain before and after treatment, serum biochemical indicators, adverse reactions and complications were compared between two groups. Results The granulation formation time and wound healing time in the experimental group were significantly shorter than those in the control group (P < 0.05). After treatment, wound edema score and pain score as well as serum levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in both groups were significantly lower than those before treatment, and these indexes after treatment in the experimental group were significantly lower than those in the control group (P < 0.05), but the differences of the above indexes before and after treatment in the experimental group were significantly higher than those in the control group (P < 0.05). After treatment, the levels of serum epidermal growth factor (EGF), fibronectin (FN) and basic fibroblast factor (bFGF) in both groups increased significantly, and these indexes after treatment in the experimental group were significantly higher than those in the control group (P < 0.05). Conclusion Chlorophyll derivative can promote granulation formation and wound healing after hemorrhoidectomy, and reduce degrees of edema and pain.

Objective     To compare the clinical efficacy and safety of da Vinci robot with totally no tube (TNT) versus subxiphoid video-assisted thymectomy surgery (SVATS) in the treatment of thymic tumors. Methods     From 2019 to 2021, a retrospective analysis was conducted on patients with thymic tumor resection in the Department of Thoracic Surgery, General Hospital of Northern Theater Command. All patients underwent total thymectomy and mediastinal fat removal, and they were divided into a TNT group and a SVATS group according to the operation method. The intraoperative blood loss, conversion rate, postoperative visual analogue score (VAS), postoperative hospital stay time and postoperative complications were compared between the two groups. Results     We finally included 435 patiets. There were 168 patients with 83 males and 85 females at an average age of 61.920±9.210 years in the TNT group and 267 patients with 147 males and 120 females at an average age of 61.460±8.119 years in the SVATS group. There was no death or postoperative myasthenic crisis in both groups. There was no statistical difference in postoperative hospital stay (1.540±0.500 d vs. 3.400±0.561 d, P=0.000), intraoperative blood loss (13.450±5.498 mL vs. 108.610±54.462 mL, P=0.000), postoperative 24 h VAS score (4.960±1.757 points vs. 3.600±1.708 points, P=0.000), or postoperative complication rate (3.0% vs. 11.6%, P=0.001). Conclusion     TNT is a more efficient, safe, and effective surgical approach for treating thymic tumors, which can shorten hospital stay time and reduce postoperative complications. However, SVATS can minimize postoperative pain.

Objective:To summarize and analyze the current application status of oral mucosal graft (OMG) technique in the repair of ureteral strictures in China, and clarify the feasibility, safety and effectiveness of this technique.Methods:The 175 patients who underwent repair of ureteral stricture using oral mucosal patches from June 2015 to February 2022 were etrospectively analyzed in 14 medical centers in China, including 49 cases in Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, 32 cases in Affiliated Seventh Medical Center of PLA General Hospital, 3 cases in The Second Hospital of Anhui Medical University, 6 cases in The First Affiliated Hospital of Zhengzhou University, 56 cases in Peking University First Hospital, 3 cases in Sir Run Run Shaw Hospital, Zhejiang University School of Medicine, 3 cases in Shanghai Sixth People' s Hospital, 4 cases in General Hospital of Estern Theater Command, 4 cases in Lanzhou University Second Hospital, 2 cases in Guizhou Province People 's Hospital, 2 cases in Peking University People' s Hospital, 5 cases in Jinzhou First People's Hospital, 5 cases in The First Affiliated Hospital of Wannan Medical College, 1 case in Shandong Provincial Hospital. In this study, 127 patients (72.6%) used lingual mucosal patches, 32(18.3%) labial mucosa, and 16(9.1%) buccal mucosa. The surgical approach for OMG ureteral reconstruction was mainly minimally invasive, with robot-assisted laparoscopy in 84 patients (48.0%), traditional laparoscopic surgery in 87 patients (49.7%), and open surgery in only 4 patients (2.3%). There were 133 males and 42 females with an average age of (35.0±17.2) years. The mean body mass index (BMI) and stenosis length were (23.1±4.1) kg/m 2 and (4.7±1.8) cm, respectively. The stricture was located in the left ureter in 116 patients, right ureter in 58 case and bilateral ureter in 1 case. The most common causes of ureteral stricture were endoscopic surgery in 88(50.3%)patients, congenital stricture in 55(31.4%)patients, failed ureteroplasty in 29(16.6%)patients, history of extracorporeal shock wave lithotripsy in 13(7.4%)patients, radiotherapy history in 3(1.7%)patients and other causes in 6(3.4%)patients. Strictures were mainly located in the upper ureter, accounting for 61.7% (108/175 cases), followed by 36.0% (63/175) at the ureteropelvic junction and 2.3%(4/175)in the middle ureter. According to the surgical methods, the patients were divided into robot-assisted laparoscopic surgery group ( n=84), traditional laparoscopic surgery group ( n=87)and open surgery group ( n=4). Subgroup analysis of patients in robot-assisted laparoscopic and traditional laparoscopic surgery groups was performed. There were no significant difference in preoperative data between the two groups except for age (32.0±18.3) years vs.(37.0±15.9)years, P=0.040], BMI[(22.5±4.3)kg/m 2 vs. (23.7±3.6)kg/m 2, P=0.028], and etiology of stenosis [endoscopic injury, 34(40.5%) vs. 53(60.9%), P=0.012]. Preoperative hydronephrosis and stricture length were assessed by CTU and ureterography. Ureterography 7-9 weeks after surgery showed patency of the reconstructed segment, or no recurrence of hydronephrosis was judged as success. Evaluate the operation method, operation time, success rate, length of OMG in repairing ureteral stricture between laparoscopic and robot-assisted groups. Results:The overall success rate of oral mucosal graft repair surgery reached 97.7%(171/175). The success rate of ureteral reconstruction in the two groups were 96.4%(81/84)and 98.9%(86/87), respectively ( P=0.351), and the difference was not statistically significant. There was no significant difference for operation time, intraoperative blood loss, and mean oral mucosal length between the robotic and laparoscopic groups[(244.7±85.8) min and (222.7±83.5)min ( P=0.116), (58.9±38.6) ml and (68.4±45.5) ml ( P=0.217), (5.0±2.0) cm and (4.6±1.5) cm ( P=0.350)], respectively.Postoperative complications were reported in 23 (13.1%) patients, such as fever, urinary leakage, lymphatic leakage, infection, but only 2 (1.4%) cases patients had complications of Clavien-Dindo score ≥ Ⅲ. The two patients developed urinary stricture after surgery with failed conservative treatment, and no urinary stricture occurred following endoscopic treatment.The short-term (three months after surgery)incidence of complications in the site where the oral mucosa was taken, such as difficulty in opening mouth, pain, and swelling, was 12.0% (21/175), and there was no significant difference for oral complications between patients harvesting different length of mucosal graft. Conclusions:Ureteroplasty with oral mucosal graft is a safe, feasible and reliable technique for ureteral reconstruction. At present, minimally invasive technology is the main surgical approach for ureteroplasty, and there is no significant difference in operation time and success rate between robotic surgery and laparoscopic surgery.

Objective:To construct a primary health care institutions performance evaluation index system from the perspective of health value orientation under the background of countywide medical alliances construction.Methods:From May 2021 to February 2022, preliminary screening was made on core performance evaluation indexes via literature review; purposive sampling was used to select the dean/vice dean, persons in charge of medical service, and those in charge of public health service responsible for performance evaluation at the community health service center. Then semi-structured interviews were made on the existing performance evaluation and assessment plans as well as existing problems of primary medical and health institutions. Based on the " input-process-output" performance evaluation model, the thematic framework analysis method was used to analyze the interview data, and combined with literature research results, a preliminary performance evaluation index system for primary medical and health institutions was built under the guidance of health value. From March to May 2022, the Delphi expert consultation method was used to evaluate the importance and operability of indexes. The threshold method was used to screen indexes, and analytic hierarchy process was used to calculate the weights of evaluation indexes.Results:The health value oriented performance evaluation index system for primary healthcare institutions included 3 first-level indexes, 9 second-level indexes, and 50 third-level indexes. The first-level indexes were output (0.377 3), input (0.336 3), and process (0.286 4) in descending order of weight. The top three weighted second-level indexes were health manpower(0.177 8), health literacy and health outcomes (0.157 6), as well as responsiveness and satisfaction (0.142 6). The third-level indexes included 17 medical indexes, 16 prevention indexes, and 17 medical prevention integration indexes. The top three weighted indexes for inpatient services were resident satisfaction with medical treatment (0.052 4), medical staff satisfaction (0.050 1), and responsiveness of residents seeking medical treatment (0.040 1); The top three weighted third-level indexes excluding inpatient services were resident satisfaction with medical treatment (0.052 4), medical staff satisfaction (0.050 1), and surplus funds used for personnel incentives (0.045 5).Conclusions:The performance evaluation index system of primary health care institutions built under the health value orientation is scientific, conducive to promoting the health-orientated transformation and improving the efficiency of primary health care services.
