Objective:To analyze the current development status and spatial distribution characteristics of traditional Chinese medicine (TCM) hospitals in China, predict the changing trends of the number of TCM hospitals, the number of beds, and the number of physicians, and provide references for the development of TCM hospitals and the formulation of related policies.Methods:From the official websites of the National Bureau of Statistics and the State Administration of Traditional Chinese Medicine, the total population and number of TCM hospitals of 31 provinces (excluding China′s Hong Kong, Macao, and Taiwan) in China from 2013 to 2022 were included, as well as the number of beds and practicing (assistant) physicians in TCM hospitals from 2013 to 2021. The grey prediction model was applied to predict the changing trends of the number of TCM hospitals, beds and physicians. Using the global Moran′s I index in spatial autocorrelation analysis, the distribution of TCM hospitals per 10 000 people in China was analyzed by spatial correlation analysis, and local G coefficient was analyzed by local hot spots.Results:From 2013 to 2027, the number of TCM hospitals, beds and practicing (assistant) TCM physicians in China all showed an increasing trend year by year. The number of TCM hospitals per 10 000 people in China showed a spatial correlation between 2013 and 2022 ( P<0.05). The hot spots of TCM hospitals were mainly concentrated in North China and Northeast China, while the cold spots were mainly concentrated in southeast coastal areas and Northwest China. Conclusions:The number of TCM hospitals in China is increasing year by year, but it is necessary to control the reasonable increase and avoid blind expansion. It is necessary to formulate regional policies of TCM hospitals according to local conditions and pay attention to the individuation of policies. Focus on hot and cold areas to promote balanced development of TCM hospitals.

OBJECTIVE To understand the current status of research on traditional Chinese medicine（TCM） human resources， and to provide a reference for expanding research ideas on TCM human resources and promoting the construction of TCM talents. METHODS From January 1， 2000 to December 31， 2022， literature related to TCM human resources was collected from the three major databases of CNKI， Wanfang and VIP. Using CiteSpace 5.8 R3 software， visualization analysis was performed for the literature in terms of publication time， journal sources， authors， institutions and areas， funding， research content， keywords， etc. RESULTS A total of 324 literature related to TCM human resources in China were included， and the number of literature issued showed an upward trend， with an annual average of 14.09 literature； 161 kinds of journals were involved， core journals accounted for 18.21% of the total publication volume； a total of 23 authors had published 2 or more literature， with a total of 55 literature published （16.98%）； a total of 416 institutions were involved， mainly schools （66.83%）； 60.49% of the literature were supported by the fund. The majorities of 324 literature were survey studies （170 literature）， and most of them used self-designed questionnaires （55 literature）； the high-frequency keywords included talent training， human resources， TCM， etc. The keywords were clustered into 7 categories， such as “human resources“”talent training“”TCM industry“”TCM services“”talent training models” “fairness” and “TCM talents”. The main problems described in the literature included insufficient talent， lack of reasonable distribution of regional structure， lack of reasonable plans for talent training， and insufficient professional knowledge and abilities. Continuously cultivating high-level talents and improving employment conditions in areas with severe human resource loss were the corresponding countermeasures proposed in the literature. CONCLUSIONS The research on TCM human resources starts late but has developed rapidly overall， and the quality of research needs to be improved； the structure of research team is single and unevenly distributed geographically； there is a structural imbalance in the allocation of human resources， as well as problems such as a shortage of professional talents， low levels of education and training and incomplete development systems.

Thyroid hormones(TH), one of the human′s essential hormones, play a crucial role in the cardiovascular system.Studies have shown that hypothermia, blood dilution, vascular endothelial injury, ischemia-reperfusion, and inflammatory factor release during cardiopulmonary bypass may cause thyroid dysfunction, leading to the euthyroid sick syndrome(ESS). There is a close correlation between ESS and postoperative low cardiac output and elevated systemic vascular resistance, which seriously affects the prognosis of pediatric patients.Studies have shown that perioperative supplementation of thyroid hormones can reduce ESS levels, especially among pediatric patients and those children with complex congenital heart disease have apparent clinical advantages.However, the results from different clinical studies varied, and currently, thyroid hormone replacement therapy is under debate.This review examines the available literature on the clinical effects of thyroid hormone on the cardiovascular system and the relationship between ESS and cardiopulmonary bypass.The clinical evidence of the treatment of ESS is gathered and discussed with an intent to find a gap for further research.

ObjectiveModern scientific methods and techniques were used to scientifically characterize the traditional softening process of Corydalis Rhizoma， so as to clarify the scientificity and rationality of the traditional process， and provide reference for inheriting the processing methods and experience of traditional Chinese medicine. MethodLow-field nuclear magnetic resonance imaging （LF-NMR/MRI） was used to characterize the water types and distribution in the softening process of Corydalis Rhizoma. Samples during the softening process was cut into thick slices and its section was observed by stereoscopic microscope. High performance liquid chromatography （HPLC） was employed to determine the content change of tetrahydropalmatine during the softening process with the mobile phase of methanol-0.1% phosphoric acid solution （60∶40， triethylamine regulated to pH 6.5） and detection wavelength at 280 nm. The determination method of softening endpoint of Corydalis Rhizoma was simulated by texture analyzer （hand pinch method）， and the softening degree of the finished products was determined after optimizing the relevant parameters. ResultLF-NMR/MRI showed that the water could penetrate through the core and distribute evenly in Corydalis Rhizoma softened by Zhangbang method. The water first entered into the medicinal material from the epidermis and stem marks in the soaking stage as the form of free water， and then penetrated into the inner core to achieve redistribution in the moistening stage. Under stereoscopic microscope， it was observed that Corydalis Rhizoma softened by the Zhangbang method could be sliced well， but the core bursting slices were easy to appear if the softening time was not enough， and the softening of samples was caused by the keratine-like powder after absorbing water. HPLC measurement showed that the loss of tetrahydropalmatine in the softening method was small， its content decreased about 5% in the soaking process， and its content was almost unchanged during the moistening process. The softening degree of Corydalis Rhizoma could be quantified by the texture analyzer， and the optimum parameters were 2 mm·s^-1 of speed before test， test speed and speed after test， 20 g of the trigger force， 20% of compression degree. The compressive force of the qualified softened Corydalis Rhizoma was 12.75-15.69 N with the relative standard deviation （RSD） of 6.8%. ConclusionModern scientific methods and techniques can characterize the scientificity and rationality of the traditional processing methods， and confirm that the Zhangbang softening method has the advantages of high efficiency， convenience and small loss of index components. The texture analyzer can simulate the softening endpoint judgment method （hand pinch method）， and realize the goal from subjective experience judgment to objective technology quantification， which has a good demonstration role for the modern inheritance of traditional processing technology.

Objective:To investigate the short-term clinical effect of using fibular flap with preserving the continuity of fibula in hip preservation surgery for femoral head necrosis.Methods:From September, 2017 to November, 2020, 13 cases of femoral head necrosis were repaired with fibular flap. The fibular flaps were cut with an improved method for preserving the continuity of the fibular cortex, and the donor sites were sutured directly. The fibuls were inserted into the femoral heads with single or double segment folding support. Autogenous iliac crest combined with platelet-rich plasma(PRP) was used for impaction of bone grafting in femoral head, and the fibular flaps were anastomosed with 1 artery and 2 veins. All follow-up data were obtained, including bone union by X-ray and CT as well as the functional recovery of the hip joint and donor site. Statistical analysis was performed. P<0.05 was considered statistically significant. Results:The followed-up time ranged from 6 to 23 months. The fibular bones were significantly thicker and the incisions healed well at the donor sites. There was neither abnormal sensation in toes, dorsal foot, and lateral of the leg, nor significant influence on foot function. The hip joint activities were normal. The outcome was proved to be remarkable according to the Harris score(from 58.9±10.6 points before surgery to 81.7±10.6 points after surgery), the difference was statistically significant ( P<0.05) . Conclusion:The method of the improved fibular flap in hip preservation surgery is beneficial to the repair and reconstruction of the necrotic femoral head since the donor area is less traumatic, and a satisfactory clinical effect can be obtained.

Objective: To investigate the anatomic tract of congenital pyriform sinus fistula (CPSF). Methods: A total of 90 patients with CPSF undergoing open surgery between August, 2007 and March, 2017 at the Department of Guangdong General Hospital were retrospectively analyzed. Results: The tracts of all the fistulas actually walked far different from those of theoretical ones. A whole fistula may be divided into 4 segments according to adjacent anatomy of CPSF. The posterior inner segment to the thyroid cartilage was initial part of the fistula. It originated from the apex of pyriform sinus, then piercing out of the inferior constrictor of pharynx inferiorly near the inferior cornu of the thyroid cartilage (ICTC), and descended between the lateral branch of the superior laryngeal nerve and the recurrent laryngeal nerve. The ICTC segment was the second part of the fistula, firstly piercing out of the inferior constrictor of pharynx and/or cricothyroid muscle, and then entering into the upper pole of thyroid. The relationship between fistula and ICTC could be divided into three types: type A (medial inferior to ICTC) accounting for 42.2% (38/90); type B (penetrate ICTC) for 3.3% (3/90); and type C (lateral inferior to ICTC) for 54.5% (49/90). The internal segment in thyroid gland was the third part of fistula, walking into the thyroid gland and terminating at its upper pole (92.2%, 83/90) or deep cervical fascia near the upper pole of thyroid (7.8%, 7/90). The lateral inferior segment to thyroid gland was the last part of the fisula, most of which are iatrogenic pseudo fistula, and started from the lateral margin of thyroid gland. Conclusions CPSF has a complicated pathway. Recognition of the tract and adjacent anatomy of CPSF will facilitate the dissection and resection of CPSF in open surgery.

Objective To analyze the outcome and the prognostic factors of hepatic veno-occlusive disease (HVOD) after hematopoietic stem cell transplantation (HSCT). Methods A total of 797 patients receiving HSCT were analyzed retrospectively. The prophylaxis regimen of HVOD in the First Affiliated Hospital of Guangxi Medical University consisted of low molecular weight heparin and lipoprostaglandin E1 (PGE1). Results Fifty-nine patients (7.4%) developed HVOD at 3-49 days after HSCT (median 12 days). Age younger than 15 years at transplant( HR=6.47, P<0.001), busulphan conditioning ( HR=6.40, P<0.001), thalassemia major ( HR=6.35,P<0.001), allogeneic transplantation ( HR=7.74, P=0.005) were univariate risk factors for HVOD. Multivariate analyses suggested that thalassemia major and busulphan conditioning were independently correlated with the development of HVOD. Conclusion Thalassemia major and busulphan conditioning are independent risk factors for HVOD after HSCT.

Objective: To explore the diagnosis, treatment and prognosis of autoimmune hemolytic anemia (AIHA) after allo-HSCT in patients with thalassemia major (TM). Methods: A retrospective analysis of AIHA status after allo-HSCT in 291 TM patients from July 2007 to December 2017 was conducted. Results: Five of the 291 TM patients (1.72%) were diagnosed with post-transplant AIHA. The median time of AIHA was 7 (5-12) months after HSCT. All post-transplant AIHA patients were positive in direct and indirect Coombs test, the main clinical manifestations were dizziness, fatigue, pale complexion, skin and sclera yellow, and soy sauce urine. The incidence of AIHA was higher after unrelated donor transplantation (6.36%, 4/63) compared with that of sibling donor transplantation (0.43%, 1/228). One patient who received only prednison was dead. Four patients who received rituximab combined with prednisolone were alive, Coombs test in two of them were negative. Conclusions AIHA after allo-HSCT developed in 1.72% patients with TM. Monitoring of Coombs test was important for diagnosis of post-transplant AIHA. The incidence of post-transplant AIHA was higher in unrelated donors compared with that of sibling donors transplantation. Treatment of rituximab combined glucocorticoid was effective strategy for post-transplant AIHA.

Background:With the progress and widely application of endoscopic techniques,the prevalence rate of periampullary diverticulum (PAD)is increasing in recent years. However,the results of studies investigating the correlation of PAD and its types with common bile duct (CBD)stone are different. Aims:To investigate the influence of PAD and its types on CBD stone. Methods:A total of 1524 consecutive inpatients who underwent diagnostic and therapeutic ERCP for pancreatobiliary diseases from Jan. 2014 to Dec. 2016 at the General Hospital of Xinjiang Military Region of Chinese PLA were enrolled and divided into two groups according to the presence or absence of PAD. Patients in PAD group were further classified into 3 subgroups by the papilla's location with respect to the diverticulum. Their clinical data were collected and retrospectively analyzed. Results:The proportion of elderly patients (≥60 years old)in PAD group was 82. 2% (310 /377),which was significantly higher than that in non-PAD group [60. 8% (697 / 1147),P < 0. 05]. The prevalences of CBD stone,gallstone associated with CBD stone,post-cholecystectomy and recurrent CBD stone were higher and the size of CBD stone was larger in PAD group than in non-PAD group (P all < 0. 05). Furthermore,stratified analysis revealed that the CBD stone was more prevalent and the size of stone was larger in type Ⅱ PAD than in type Ⅰ and type Ⅲ PAD (P <0. 05), while recurrent CBD stone was more frequent in type Ⅰ and type Ⅱ PAD than in type Ⅲ PAD (P < 0. 05). Multivariate analysis indicated that the elderly and PAD were the risk factors for recurrence of CBD stone,and cholecystectomy was a protective factor. Conclusions:The elderly is predisposed to PAD. PAD and its types are associated with the development and recurrence of CBD stone. CBD stone is more prevalent in patients with PAD especially type Ⅱ PAD. The size of stone is larger and the post ERCP recurrence rate is high in type Ⅱ PAD.
