Objective To analyze the medication patterns of LAN Shi Mi Cang in treating diseases related to the spleen and stomach.Methods Search for prescriptions for treating spleen and stomach-related diseases in LAN Shi Mi Cang,a total of 95 prescriptions and 150 traditional Chinese medicines were included.The usage frequency,four Qi,five Wei and channel tropism of traditional Chinese medicine were analyzed,and the correlation degree,core drugs and new formula combinations were analyzed by using correlation analysis,cluster analysis and complex network analysis.Medication rules of Li Dongyuan in treating diseases related to spleen and stomach were summarized.Results The top three most frequently used herbs are Danggui,Shengma,and Gancao.These herbs generally exhibit warm,neutral,or cold properties,with flavors predominantly pungent,sweet,or bitter,primarily affecting the spleen and stomach meridians.The most closely associated herb pair is Danggui-Shengma.Core herbs include Huangqi,Shengma,and Chaihu,et al.Cluster analysis identified four distinct herbal combinations.Conclusion Li Dongyuan's treatment of diseases related to the spleen and stomach mainly focuses on tonifying the spleen and stomach,harmonizing Qi and blood,sweet and warm to remove heat,and raising Yang to disperse fire.It also treats external infections and internal injuries,as well as symptoms of excess and root deficiency.

Objective:To compare the survival outcomes of different subsequent treatment regimens in patients with locally advanced hypopharyngeal squamous cell carcinoma (HPSCC) who achieved partial response (PR) after neoadjuvant chemotherapy based on the gross tumor volume regression rate (GTVRR).Methods:This retrospective study included patients with locally advanced HPSCC treated at the Department of Head and Neck Surgery, Beijing Tongren Hospital, from January 2011 to December 2023. The cohort included 135 males and 3 females, aged from 35 to 77 years. All patients received 2-3 cycles of TPF regimen (paclitaxel+cisplatin+5-fluorouracil) neoadjuvant chemotherapy. Subsequent treatments included concurrent chemoradiotherapy or surgery combined with postoperative adjuvant radiotherapy. The impacts of different subsequent treatment modalities on the survivals and prognoses of patients were compared based on GTVRR thresholds of 50% and 70%. The χ 2 test was used to analyze influencing factors; survival analysis and intergroup comparisons were performed using the Kaplan-Meier method and Log-rank test; prognostic factors were assessed using univariate and multivariate Cox regression analyses. Results:The 5-year OS and PFS rates were 56.5% and 47.9%, respectively, while, the 10-year OS and PFS rates were 25.8% and 21.2%, respectively. The median OS was 75 months, and the median PFS was 48 months. The laryngeal function preservation rate for the entire cohort was 83.3%. The patients who underwent surgery combined with postoperative radiotherapy had significantly better OS and PFS outcomes than those treated with concurrent chemoradiotherapy ( P<0.05). Stratification based on GTVRR revealed that the surgery plus postoperative radiotherapy regimen was particularly effective for PR patients with a GTVRR of 30%-70%, showing significantly better OS and PFS compared to the concurrent chemoradiotherapy group ( P<0.05). Conclusion:The optimal subsequent treatment for PR-HPSCC may be surgery-based comprehensive treatment, particularly for patients with a GTVRR of 30%-70%. This study offers valuable insights for the stratified treatment of HPSCC, which could contribute to improving overall patient prognosis.

Objective To investigate the impact of total parathyroidectomy with autotransplantation (tPTx+AT)on bone mineral density and serum soluble Klotho (sKlotho)level in patients with secondary hyperparathyroidism (SHPT).Methods A total of 86 patients undergoing tPTx+AT in the Second Affiliated Hospital of Anhui Medical University from June 2019 to May 2022 were recruited in this study.Their demographic characteristics were collected before surgery,along with serum levels of corrected calcium,phosphorus,intact parathyroid hormone (iPTH),alkaline phosphatase (ALP),fibroblast growth factor 23 (FGF23),and sKlotho before and at 5 d,and 1,3,6,12 and 24 months after surgery.Dual energy X-ray absorptiometry was used to determine the BMD values of the lumbar spine L1-L4 before surgery and at 3,6,12 and 24 months after surgery.The changes in BMD and serum FGF23 and sKlotho levels before and after tPTx+AT were observed.Results Surgical treatment was successfully completed in all 86 patients,with their clinical symptoms such as bone pain and skin itching significantly improved postoperatively,and markedly decreased serum calcium,phosphorus,iPTH,ALP and FGF23 levels.The sKlotho level was significantly lower at 5 d postoperatively than that preoperatively,with that at 1 month after surgery increased by approximately 24.5％ than the preoperative level,and then the level was in a stable trend.The BMD values at the lumbar spine L1-L4 were increased postoperatively,and reached the highest levels at 12 months postoperatively.Further analyses showed that dialysis vintage,duration of SHPT,and ALP,iPTH and FGF23 levels were negatively correlated with the Z-scores of the lumbar spine L1-L4,while sKlotho level was positively correlated with the Z-scores.Conclusion tPTx+Atcan significantly improve the clinical symptoms of SHPT patients,regulate the balance of calcium and phosphorus metabolism,increase sKlotho level and reduce FGF23 level.It is an effective method to improve BMD.

Objective To investigate the correlations of serum cell division cycle 42 (CDC-42), β₂-microglobulin (β₂-MG) and fibulin 1 (FBLN1) levels with abdominal aortic calcification (AAC) in patients with maintenance hemodialysis (MHD). Methods General information and biochemical indicators of 74 MHD patients were collected, and they were divided into no to mild AAC group (n=36) and moderate to severe AAC group (n=38) based on the Abdominal Aortic Calcification Score (AACs). Serum levels of CDC-42, β₂-MG and FBLN1 were compared between the two groups, and multivariate Logistic regression analysis was used to explore the risk factors for AAC in MHD patients. Results The dialysis vintage, serum phosphorus, intact parathyroid hormone (iPTH), CDC-42, β₂-MG and FBLN1 levels in the moderate to severe AAC group were significantly higher than those in the no to mild AAC group (P < 0.05). AAC in MHD patients was positively correlated with serum phosphorus, iPTH, CDC-42, β₂-MG, FBLN1, and dialysis vintage (P < 0.05). High levels of CDC-42, β₂-MG and FBLN1 as well as long dialysis vintage were independent risk factors for AAC in MHD patients (P < 0.05). Conclusion Serum CDC-42, β₂-MG and FBLN1 levels are positively correlated with AAC in MHD patients. High levels of CDC-42, β₂-MG and FBLN1 as well as long dialysis vintage are independent risk factors for AAC in MHD patients.

Objective:To discuss the characteristics of ultrasound diagnosis of optic disc capillary hemangioma.Methods:The study analyzed retrospectively 7 cases of optic disc capillary hemangioma diagnosed in the Beijing Tongren Hospital from 2015 to 2018. The size, morphology, internal echo, and secondary changes of the lesion were analyzed during ultrasound examination.Color Doppler flow imaging was used to check the blood flow in the lesion.Results:Pre-optic disc occupying lesions could be detected in the ultrasound images of the 7 cases. Lesion size: average base diameters (5.39±1.90)mm×(4.79±1.28)mm, average height (3.61±1.37)mm. Lesion morphology: 5 cases were round, and 2 cases were irregular. Echo within the lesion: 3 cases had medium echo inside the lesion, and 4 cases had high echo inside the lesion. Internal echo characteristics: 5 cases had uniform echo, and 2 cases had uneven echo. Secondary changes: 6 cases had secondary retinal detachment and vitreous opacity, and 1 cases was accompanied by retinal hemangioma in other parts. In all cases, blood flow signals could be detected inside the space-occupying lesions, which were in the form of branches, stripes or spots, and the blood flow spectrum showed a parallel spectrum of arteries and veins.Conclusions:Ultrasound examination of optic disc capillary hemangioma has certain characteristics, which can provide a valuable follow-up basis for clinical diagnosis.

Objective:To understand the viral genomic characteristics of a 2019-novel coronavirus (2019-nCoV) strain in the first COVID-19 patient found in Hangzhou, China.Methods:Viral RNA was extracted in throat swab and sputum sample of the patient and was performed real-time reverse transcription PCR detection and obtained viral genome by high-throughput sequencing method. Phylogenetic analysis was conducted using 29 2019-nCoV genomes and 30 β-coronavirus genomes deposited in NCBI GenBank. Fifteen genomes from Wuhan were grouped by mutation sites and others were identified by Wuhan's or specific mutation sites.Results:A 29 833 bp length genome of the first 2019-nCoV strain in Hangzhou was obtained, covering full length of the coding regions of coronavirus. Phylogenetic analysis showed that the genome was closest to the genome of a bat SARS-like coronavirus strain RaTG13 with an identity of 96.11% (28 666/29 826). Among the genes between two genomes, E genes were highly conserved (99.56%), while S genes had lowest identity (92.87%). The genome sequence similarities among 29 strains from China (Hangzhou, Wuhan, and Shenzhen), Japan, USA, and Finland, were all more than 99.9%; however, some single nucleotide polymorphisms were identified in some strains.Conclusion:The genome of Hangzhou 2019-nCoV strain was very close to the genomes of strains from other cities in China and overseas collected at early epidemic phase. The 2019-nCoV genome sequencing method used in this paper provides an useful tool for monitoring variation of viral genes.

Objective To determine the key interventions transferring from the control to elimination of malaria in China so as to provide the basic information for achieving malaria elimination. Methods Based on the data collected from the document entitled of The National Annual Report on Schistosomiasis,Malaria and Echinococcosis,published by the National Institute of Parasitic Diseases of Chinese Center for Disease Control and Prevention,the malaria incidence and intervention data were se?lected only in the typical endemic provinces during the period of 2004-2010. The correlation between the incidence and interven?tions in the target provinces was analyzed based on the Panel Data Regression Model,and the key interventions were deter?mined. Results Four provinces namely Anhui,Yunnan,Hainan and Henan were targeted with 87.56%of the national malaria figures from 2004 to 2010. When Y was given as vivax malaria incidence,X1 as the log of the number of historical cases receiving radical treatment in the pre?transmission stage(RTPT)(F=14.53,P<0.01,R2=0.72),X2 as the log of risk population receiv?ing RTPR(F=15.90,P<0.01,R2=0.71)and X3 as the number of technicians trained in microscopy(F=11.53,P<0.01,R2=0.61),three space?fixed effect models were established respectively,and X1,X2,as well as X3 had negative effects on Y value. When Y was given as falciparum malaria incidence,X1 as the accumulated technicians trained in microscopy(F=11.06,P<0.01,R2=0.87),X2 as the log of technicians trained in entomology(F=15.28,P<0.01,R2=0.89),two two?way(space and time)fixed effect models were established respectively,and both X1 and X2 had negative effects on Y value. Conclusion RTPT among historical patients and at?risk populations as well as microscopy training influences the variation of vivax malaria inci? dence,while the significant interventions of microscopy training and vector control training indicate that the integrated measures with strengthened capacity in diagnosis and vector control are of importance in the control of falciparum malaria transmission.
