Traditional Chinese Medicine (TCM), as a treasure of the Chinese nation, plays a significant role in maintaining public health. In 2019, the Central Committee of the Communist Party of China and the State Council proposed for the first time the establishment of a TCM registration and evaluation evidence system that integrates TCM theory, "personal experience" and clinical trials (referred to as the "Three-in-One" System) to promote the inheritance and innovation of TCM. Subsequently, the National Medical Products Administration issued several guiding principles to advance the improvement and implementation of this system. Owing to the complexity of its implementation, there are still differing understandings within the TCM industry regarding the positioning of the "Three-in-One" Registration and Evaluation Evidence System, as well as the connotation and value orientation of the "personal experience." To address this, Academician WANG Qi, President of the TCM Association, China International Exchange and Promotion Association for Medical and Healthcare and TCM master, led a group of academicians, TCM masters, TCM pharmacology experts and clinical TCM experts to convene a "Seminar on Promoting the Implementation of the ′Three-in-One′ Registration and Evaluation Evidence System for Chinese Medicinals." Through extensive discussions, an expert consensus was formed, clarifying the different roles of the TCM theory, "personal experience" and clinical trials within the system. It was further emphasized that the "personal experience" is the core of this system, and its data should be derived from clinical practice scenarios. In the future, the improvement of this system will require collaborative efforts across multiple fields to promote the high-quality development of the Chinese medicinal industry.

Objective:To evaluate the efficacy and safety of mitoxantrone hydrochloride liposome injection in the treatment of peripheral T-cell lymphoma (PTCL) in a real-world setting.Methods:This was a real-world ambispective cohort study (MOMENT study) (Chinese clinical trial registry number: ChiCTR2200062067). Clinical data were collected from 198 patients who received mitoxantrone hydrochloride liposome injection as monotherapy or combination therapy at 37 hospitals from January 2022 to January 2023, including 166 patients in the retrospective cohort and 32 patients in the prospective cohort; 10 patients in the treatment-na?ve group and 188 patients in the relapsed/refractory group. Clinical characteristics, efficacy and adverse events were summarized, and the overall survival (OS) and progression-free survival (PFS) were analyzed.Results:All 198 patients were treated with mitoxantrone hydrochloride liposome injection for a median of 3 cycles (range 1-7 cycles); 28 cases were treated with mitoxantrone hydrochloride liposome injection as monotherapy, and 170 cases were treated with the combination regimen. Among 188 relapsed/refractory patients, 45 cases (23.9%) were in complete remission (CR), 82 cases (43.6%) were in partial remission (PR), and 28 cases (14.9%) were in disease stabilization (SD), and 33 cases (17.6%) were in disease progression (PD), with an objective remission rate (ORR) of 67.6% (127/188). Among 10 treatment-na?ve patients, 4 cases (40.0%) were in CR, 5 cases (50.0%) were in PR, and 1 case (10.0%) was in PD, with an ORR of 90.0% (9/10). The median follow-up time was 2.9 months (95% CI 2.4-3.7 months), and the median PFS and OS of patients in relapsed/refractory and treatment-na?ve groups were not reached. In relapsed/refractory patients, the difference in ORR between patients with different number of treatment lines of mitoxantrone hydrochloride liposome injection [ORR of the second-line, the third-line and ≥the forth-line treatment was 74.4% (67/90), 73.9% (34/46) and 50.0% (26/52)] was statistically significant ( P = 0.008). Of the 198 PTCL patients, 182 cases (91.9%) experienced at least 1 time of treatment-related adverse events, and the incidence rate of ≥grade 3 adverse events was 66.7% (132/198), which was mainly characterized by hematologic adverse events. The ≥ grade 3 hematologic adverse events mainly included decreased lymphocyte count, decreased neutrophil count, decreased white blood cell count, and anemia; non-hematologic adverse events were mostly grade 1-2, mainly including pigmentation disorders and upper respiratory tract infection. Conclusions:The use of mitoxantrone hydrochloride liposome injection-containing regimen in the treatment of PTCL has definite efficacy and is well tolerated, and it is a new therapeutic option for PTCL patients.

ObjectiveTo evaluate the efficacy and safety of An'erning granules in the treatment of community-acquired pneumonia in children. MethodA randomized， double-blind， single-simulation， placebo-controlled trial was designed in this study. The children were randomly assigned into an observation group （An'erning granules combined with ceftriaxone sodium） and a control group （An'erning granules placebo combined with ceftriaxone sodium） according to the ratio of 2∶1. The disease cure rate was taken as the main indicator of efficacy， and the safety of An'erning granules was observed. ResultA total of 206 children （137 in the observation group and 69 in the control group） were included in this study. Before treatment， the age， sex， body height， body weight， diagnosis time of pneumonia， and symptom and sign scores had no significant differences between the two groups. After 8 days of continuous medication， the observation group［70.80%（97/137）］ had higher cure rate than the control group［56.52%（39/69）］（χ²=4.17，P<0.05） and total effective rate of chest X-ray ［97.98%（97/99）］ than the control group［86.27%（44/51）］ （χ²=12.98，P<0.01）. The observation group was superior to the control group in the alleviation of TCM syndrome under the condition of 0-3 g dose stratification on day 3 of medication （P<0.01）. The recovery time， time to complete fever abatement， time to fever abatement and expectoration alleviation， rate of conversion to severe case， and reduction in the frequency of antibiotic use showed no significant differences between the two groups. In terms of safety， 13 and 7 adverse events occurred in the observation group and control group， respectively， which were relieved or disappeared after drug withdrawal or symptomatic treatment and showed no significant difference between the two groups. ConclusionIntravenous drip of ceftriaxone sodium combined with An'erning granules is effective in the treatment of community-acquired pneumonia in children. It can accelerate the absorption of pulmonary inflammation， alleviate the clinical symptoms in a short time for young children or the children with mild symptoms， and is safe in clinical application.

Objective:To evaluate the global and segmental myocardial work in patients with cardiac amyloidosis (CA) by left ventricular pressure-strain loop (PSL) noninvasively.Methods:Eighteen patients with CA in Beijing Chao-Yang Hospital from March 2018 to December 2020 were included as CA group, 20 healthy subjects were selected as control group. The global longitudinal strain (GLS) and mechanical dispersion (MD) of left ventricle were analyzed by two-dimensional speckle tracking imaging. The left ventricular PSL was used to assess global work index (GWI), global constructive work (GCW), global waste work (GWW), and global work efficiency (GWE). The mean value of left ventricular basal, mid and apical myocardial work index (MWI), constructive work (CW), waste work (WW) and work efficiency (WE) were calculated and compared between the two groups.Results:①Compared with the control group, GLS was decreased and MD was increased in CA group (all P<0.05). ②GWI, GCW, GWW and GWE were decreased in CA group compared with the control group (all P<0.05). ③In CA group, the MWI, CW and WE of the basal, mid and apical segments were lower than those of control group (all P<0.05), WW of the basal and mid segments were lower than those of apical segment(all P<0.05). The impairment of MWI, WW and WE in basal and mid segment were more significant than those of apical segment (all P<0.05). ④GWI, GCW and GWE were positively correlated with GLS ( r=0.854, 0.816, 0.748; all P<0.001) and LVEF ( r=0.674, 0.634, 0.650; all P<0.01), and negatively correlated with MD ( r=-0.657, -0.672, -0.710, all P<0.01). GWI and GCW were negatively correlated with E/e′ ( r=-0.493, -0.539; all P<0.05). Conclusions:The global, basal, mid and apical left ventricular myocardial work indices are decreased in CA patients. MWI, CW and WE show an apical sparing pattern. Quantitative assessment of myocardial work by PSL may provide more valuable information for CA patients.

Objective:To investigate the clinical, pathological and immunohistochemical features of seromucinous neoplasms, including seromucinous cystadenoma, borderline tumour and seromucinous carcinomas of the ovary.Methods:A retrospective review of the seromucinous neoplasms collected between June 2006 and December 2018 was conducted at the First Medical Center of PLA General Hospital. EnVision immunohistochemical staining was used to detect the expression of CK7, PAX8, ER, PR, WT1, p16, p53 and Baf250a which was encoded by the ARID1A gene.Results:A total of 75 ovarian seromucinous neoplasms were included. There were 30 cases of benign seromucinous cystadenoma, whose patients aged 12 to 83 years (mean, 36 years). The tumor histologically composed of endocervical-type mucinous epithelium and serous-type cells, each of which accounted for more than 10%. Among the 34 cases of seromucinous borderline tumour including 7 cases with concurrent endometriosis, the patients aged 21 to 72 years (mean, 39 years). Characteristic histologic features were broad papilla structure and an admixture of cell types, predominant endocervical-like mucinous cells (non-intestinal, no goblet cells), eosinophilic cells and others such as clear cells, hobnail cells, ciliated cells, and endometrioid cells. The larger papillae tended to have oedematous stroma containing neutrophils. In the 11 cases of seromucinous carcinomas including 2 cases with concurrent endometriosis, patients aged 26 to 61 years (mean, 40 years). Seromucinous carcinomas exhibited a predominant papillary architecture with smaller components of confluent glandular, microglandular and solid structure, expansive stromal invasion pattern, and sometimes locally destructive infiltration. An admixture of epithelial cell types was in seromucinous carcinomas, as well as borderline tumour. Immunohistochemically, the tumours were positive for CK7, PAX8, p16, estrogen receptor and progesterone receptor (positive in 10% to 80% of the cases). They were negative for WT1, while p53?staining showed a "wild-type" pattern. The Ki-67 positive rate was 20% to 60%. Loss of ARID1A-encoded protein Baf250a staining was observed in 6 (30%) of the 20?seromucinous borderline tumors, and 2 of the 11?seromucinous carcinomas. According to FIGO 2014?staging system, there were 4 cases of ⅠA, 3 cases of ⅡA and 4 cases of ⅢC. Follow-up information was available in 9 patients of seromucinous carcinomas, and 2 lost to follow-up. Eight were alive (follow-up for 6 to 108 months), including 2 patients with relapse, but 1 patient who initially presented with a stage ⅢC tumor died of disease 60 months after the cancer diagnosis. Thirty-four patients of borderline tumour were all alive at the end of follow-up, including 1 with relapse.Conclusions:Seromucinous neoplasms have characteristic histopathological and immunopathological features. Both borderline tumors and carcinomas have complex structures and cellular components. ARID1A as a tumor-suppressor gene plays a role in the oncogenesis of ovarian seromucinous neoplasms. The loss of staining with ARID1A-encoded Baf250a and wild-type p53 in seromucinous neoplasms together support that seromucinous neoplasms could be type Ⅰ tumor of dualistic model of epithelial ovarian cancer, with favourable prognosis.

Objective:To compare the clinical and histopathological characteristics of cervical adenoid basal cell carcinoma and adenoid cystic carcinoma for improving the diagnosis accuracy and differential diagnosis of these tumors.Methods:A retrospective study was conducted on 9 cases of cervical adenoid basal cell carcinoma and 3 cases of adenoid cystic carcinoma which were diagnosed and consulted at the First Medical Center of PLA General Hospital from March 2009 to April 2019. Detailed clinical data were reviewed. All pathological sections and immunohistochemical results were reviewed and the clinicopathological characteristics were analyzed. Follow-up information by telephone was collected and relevant literature was consulted.Results:Both tumors were more commonly found in postmenopausal women (the age of onset ranged 43-74 years). Adenoid basal cell carcinoma was often clinical asymptomatic. Most of them presented as abnormal smears of the cervix during physical examination, and there was no definite mass in colposcopy.Adenoid cystic carcinoma was mostly presented with abnormal vaginal bleeding. A mass was seen in colposcopy.Histologically, the two tumors were characterized by nest-like growth of the tumors, consisting of basal-like tumor cells, and often surrounded by palisade structures. The two lesions might coexist, or be mixed with squamous cell carcinoma or high-grade squamous intraepithelial lesions. The difference was that adenoid basal cell carcinoma was mostly located at the junction of cervical squamous epithelium and columnar epithelium and beneath the overlying epithelium, the tumor cells were arranged in nests, with squamous differentiation in the center of the nests, or in double-layer adenoid arrangement. The cell morphology was bland with occasional mitoses, and the stromal reaction was not obvious. And adenoid cystic carcinoma cells in the nest arranged like a sieve, the homogenous red-stained and blue-stained secretions were observed in the sieve holes, with obvious cell atypia, frequent mitoses, and obvious stromal reaction.In one case of adenoid cystic carcinoma, sarcomatoid area presented around the nests.Both of them were positive in clinical HPV test. Among the 9 cases of adenoid basal cell carcinoma, 3 were tested for HPV and 5 were tested for p16, and all showed positive expression. Among the 3 cases of adenoid cystic carcinoma, 2 were tested for HPV and 3 were tested for p16, both of which showed positive expression. Telephone follow-up was conducted by June 2019(follow-up time ranged 2-37 months). No recurrence or metastasis occurred in 7 of the 9 cases of adenoid basal cell carcinoma, while 1 case had a ground-glass nodule in lung and another had recurrence of vaginal stump 32 months after the surgery.One case of adenoid cystic carcinoma developed lung metastasis 8 months after surgery and died 2 years after surgery; another case was followed up for 6 months, which showed no recurrence or metastasis; the third case was lost to follow-up.Conclusions:Both adenoid cystic carcinoma and adenoid basal cell carcinoma of the cervix are the tumors originating from cervical reserve cells and are associated with high-risk HPV infection. Due to the differences in clinical treatment and prognosis, careful histological evaluation and immunohistochemical analysis should be carried out to make accurate pathological diagnosis.

Objective: To explore whether social support has a moderating effect on the relationship between negative emotions including depression, anxiety, stress with suicidal behaviors, and to provide reference for the suicide prevention among college students. Methods: Three universities were selected in Qinghai, Ningxia and Xinjiang province, and 4 893 college students were selected using cluster sampling method. The Social Support Scale, Depression-Anxiety-Stress Scale(DASS) and Suicidal Behavior Questionnaire-Revised self-evaluation questionnaires were used to collect data. Hierarchical linear regression model was employed to explore the moderating effect of social support. Results: A total of 4 893 college students completed full questionnaires and included in the final analysis. Among them, 738(15.08%) were under high risk of suicidal behaviors. The regression model showed that DASS score was positively associated with suicidal behavior (β=0.31, P<0.01), and social support was negatively associated with suicidal behavior (β=-0.08, P<0.01); Additionally, the interaction between social support and DASS negatively correlated with suicidal behavior (β=-0.05, P<0.01). Conclusion Social support may have buffering effects on the relationship between negative emotions (depression, anxiety and stress) and suicidal behaviors.

Objective To investigate the clinical and histopathological features of cervical basal squamous cell carcinoma (BSCC). Methods A retrospective analysis of 10 cases of cervical BSCC was carried out. The clinical data and all the pathological sections were reviewed, the related immunohistochemical results were statistically analyzed, the clinicopathological features were analyzed, and then followed the prognosis. Results (1) Clinical features:the median onset age of BSCC in cervix was 51 years old (ranged 35-69 years old), 5 of them were postmenopausal women. Vaginal bleeding was often seen in clinic (7 cases). Of the 10 cervical BSCC patients, 5 tested HPV types. All of them were HPV positive, including 2 cases of HPV 16 positive and 1 case of high-risk HPV positive. At the time of colposcopy, 3 cases showed exogenous nodular mass, 3 cases showed endogenous infiltrating mass, and 4 cases had unclear type of mass.(2)Treatment:of the 10 patients, 8 underwent hysterectomy+bilateral adnexal excision+pelvic lymphadenectomy, of which 6 underwent radiotherapy or chemotherapy after operation. Radiotherapy and chemotherapy were performed only in 2 cases. (3) Pathological features: histologically, the tumor cells were nests and stripe like growth, which were composed of basal like tumor cells. The cells had obvious heteromorphosis, less cytoplasm, deep dyed nuclei and common nuclear mitosis, and there were often palisade like structures around the cell nests, and some cells in the center of the cell nests were found to have acne like necrosis. It could be mixed with normal squamous cell carcinoma and squamous epithelial lesion. Among the 10 patients, 6 had immunohistochemical results. BSCC mainly expressed p16 and squamous cell markers such as p63, cytokeratin (CK) 5/6 and p40 protein, the positive expression rates were 3/3, 3/3, 2/2 and 3/3, respectively.A few expressed CK7 protein, and the positive expression rate was 1/3. (4) Prognosis:follow-up time ranged from 1 week to 64 months, and 2 cases were lost to follow-up. Among the 8 follow-up patients, 3 had iliac bone, lung or skin metastasis, and 5 had no recurrence or metastasis during the follow-up period. Conclusions BSCC of cervix is a rare malignant tumor of cervix associated with high-risk HPV infection, p16 is more positive. The treatment is similar to that of normal cervical squamous cell carcinoma. Surgical resection and radiotherapy and chemotherapy are the most effective methods according to the clinical stage . At present, the disease is considered to be highly aggressive and the poor prognosis.

Objective To explore the availability and safety of ileal ureter replacement combined with ileal augmentation cystoplasty in treating ureteral stenosis with contracted bladder.Methods From August 2015 to November 2018,three patients who underwent ileal ureter replacement combined with augmentation cystoplasty were treated with ileal ureter replacement combined with augmentation cystoplasty.There were 1 male and 2 females with the age ranging from 34 to 55 years (mean 39 years).Two patients suffered from left ureter stenosis,and one patient had stenosis on the both sides.The length of the ureter stenosis ranged from 6 to 18 cm (mean 9.8 cm).The preoperative bladder capacity ranged from 60 to 150 ml (mean 103.3 ml).In the surgery,part of ileum was used to replace the ureter,and the distal intestine was made into U-shape to enlarge the bladder.Results All operation were completed successfully.The operation time ranged from 220 to 400 min (mean 303.0 min),and the blood loss ranged from 150 to 500 ml (mean 283.3 ml).Laparoscopic surgery was performed in 1 case and open surgery in 2 cases.Three weeks after the surgery,the bladder volume underwent cystography ranged from 300 to 400 ml (mean 360.0 ml).Three months after the surgery,the postvoid residual urine volume ranged from 20 to 50 ml (mean 33.3 ml).Postoperative frequency and urgency of urine were completely relieved in 1 case,alleviated in 2 cases.Flank pain was completely relieved in 1 case,and alleviated in 2 cases postoperatively.The serum creatinine of 2 patients mildly increased after the surgery,while 1 patient remained stable.For complications,1 patient had urinary infection,and 1 patient suffered from metabolic acidosis.Conclusions Ileal ureteral replacement combined with augmentation cystoplasty can be the choice of treatment for long segment ureteral stenosis and enlarge the bladder simultaneously.The postoperative complications and the kidney functions should be regularly followed up.

Objective: To evaluate the efficacy and safety of Institution Urology of Peking University modified technique for transperitoneal laparoscopic pyeloplasty combined with deflectable tip rigid ureteroscope(the Sun's ureteroscope) in ureteropelvic junction obstruction(UPJO) complicated with renal calculi. Methods: From January 2018 to September 2018, eight patients, including five males and three females, were diagnosed as UPJO with coexistent ipsilateral renal calculi in Peking University First Hospital and Changzheng Hospital of Second Military Medical University. The age ranged from 14 to 50 years(mean 28 years). Four patients had flank pain and one patient had flank pain with hematuria, while the other three patients came without clinical symptom.The BMI ranged from 16.8 to 26.2 kg/m²(mean 22.0 kg/m²). The lesion located on the left side in 4 cases and on the right side in 4 cases. One patient suffered with multiple pelvis stones. Four patients suffered with multiple lower calyceal stones, and 3 patients had solitary lower calyceal stone. The stone size ranged from 2 mm to 10 mm (mean 6.4 mm). 3 cases had slight hydronephrosis and 5 cases had moderate hydronephrosis. Two patients combined with crossing vessels. All patients underwent modified transperotoneal laparoscopic dismembered pyeloplasty with pyelolithotomy. In cases with left lesion, an incision was made for the veress needle 5mm inferior to the costal margin in the left midclavicular line to establish pneumoperitoneum . A 12-mm camera port was placed 30 mm inferior to the umbilicus and 10 mm lateral to the border of left rectus muscle. Then, a 5 mm operative trocars was inserted at 30mm superior to the umbilicus 10 mm lateral to the border of left rectus muscle. Another 12 mm operative trocar was inserted at the opposite McBurney point. The last 5 mm operative trocar was placed at the veress needle point. After visualizing the pelvis and the proximal ureter at the lower pole of the kidney, a 1.0 cm transverse incision on the lower pole of the pelvis above the obstruction site was made. The Sun’s ureteroscope was introduced into the renal pelvis through the 1.0 cm transverse incision via the 12-mm trocar below the umbilicus. Stones in the renal pelvis and calyces were extracted with basket catheters and removed via the port. After the pyelo-nephroscopy, a modified transperitoneal laparoscopic pyeloplasty was made. A F6 double-J stent was inserted into the ureter during the surgery. Result: All surgeries were finished successfully without conversion. The surgical duration ranged from 111 to 185 min(mean 135 min). The estimated blood ranged from 10 to 50 ml(mean 38.8 ml). The hospital stay ranged from 3 to 7 days(mean 4 days). The intraoperative stone free rate was 100%(8/8). No perioperative complications occured. With the follow-up from 6 to 14.4 months(mean 8.9 months), there was no evidence of obstruction in all patients, as confirmed by symptoms or radiological improvement of hydronephrosis, and two patients found recurrence of renal calculi. Conclusions Our modified technique for transperitoneal laparoscopic pyeloplasty combined with deflectable tip rigid ureteroscope(the Sun′s ureteroscope) is a safe, effective method to manage ureteropelvic junction obstruction with renal calculi.
