OBJECTIVE To observe the clinical efficacy and effect on serum thymic stromal lymphopoietin(TSLP)levels of pa-tients with advanced liver cancer of qi deficiency and toxic stasis type by Jiawei Yupingfeng San.METHODS Using random double blind method,120 patients with advanced liver cancer of qi deficiency and toxic stasis type were randomly divided into 3 groups:Jiawei Yupingfeng San group,Yupingfeng San group,and placebo group,each consisting of 40 cases.All patients in the 3 groups were given conventional treatment such as radiotherapy,chemotherapy,interventional or targeted therapy;Jiawei Yupingfeng San group was given Jiawei Yupingfeng San granules,Yupingfeng San group was given Yupingfeng San granules,and placebo group was given placebo.The course of treatment was 2 months.The changes of Karnofsky functional status score(KPS score),TCM syndrome score,tumor size and serum TSLP level in the 3 groups were observed before and after treatment,and the correlation between the changes of tumor size and TSLP was analyzed.RESULTS After treatment,the KPS scores of Yupingfeng San group and Jiawei Yupingfeng San group were sig-nificantly increased(P<0.05,P<0.01),TCM syndrome score were decreased(P<0.01),tumor growth(P<0.05,P<0.01)was de-layed,and serum TSLP levels(P<0.05,P<0.01)were decreased.Furthermore,there was a slight positive correlation between chan-ges in tumor size and changes in TSLP(P<0.05).In terms of improving tumor size,the curative effect of Jiawei Yupingfeng San group was better than that of Yupingfeng San group(P<0.05).During the treatment period,no obvious adverse reactions were observed in the 3 groups of patients.CONCLUSION Combined with conventional treatment,Jiawei Yupingfeng San can significantly delay tumor growth in patients with advanced liver cancer of qi deficiency and toxic stasis type and improve patients'TCM syndromes and their qual-ity of survival.The therapeutic mechanism is related to reducing the expression of serum TSLP and improving the immune status of pa-tients,thereby delaying the growth of tumors.

Objective:To evaluate the effect of the impaction of posterior wall on the prognosis following open reduction and internal fixation for fractures of acetabular posterior wall.Methods:A retrospective study was conducted to analyze the data from the 83 patients with fracture of acetabular posterior wall who had been consecutively treated by open reduction and internal fixation at Department of Orthopaedics and Traumatology, Beijing Jishuitan Hospital from January 2017 to December 2020. The patients were divided into 2 groups based on involvement of posterior wall impaction. In the impaction group of 33 cases, there were 26 males and 7 females with an age of (47.4±11.6) years; in the non-impaction group of 50 cases, there were 43 males and 7 females with an age of (41.3±12.0) years. The quality of postoperative fracture reduction, the function of the affected hip at the last follow-up, and the complication rate during follow-up were compared between the 2 groups. Multifactorial binary logistic regression and age subgroups were used to analyze the effects of posterior wall impaction on functional outcomes.Results:The age, rate of associated injuries in other body parts, and rate of posterior wall comminution in the impaction group were significantly higher than those in the non-impaction group ( P<0.05), but there was no statistically significant difference in other general data of patients between the 2 groups ( P>0.05). All patients were followed up for (44.5±13.3) months after surgery. The rate of anatomical reduction in the non-impaction group (96.0%, 48/50) was significantly higher than that in the impaction group (57.6%, 19/33) ( P<0.05), and the good and excellent rate by the modified Merle d'Aubigné & Postel scale at the last follow-up in the non-impaction group (84.0%, 42/50) was significantly higher than that in the impaction group (51.5%, 17/33) ( P<0.05). There was no significant difference in the incidence of complications between the 2 groups ( P>0.05). After adjusting for age and gender, the difference in hip function was still significantly different between the 2 groups ( OR=0.23, 95% CI: 0.06 to 0.79, P=0.020). The effect of posterior wall impaction on functional outcomes was statistically significant in patients aged ≥50 years ( P=0.008), whereas the difference was not statistically significant in patients aged <50 years ( P=0.194). Conclusions:Compared with non-impaction ones, acetabular fractures of posterior wall impaction tend to lead to poorer quality of reduction, which in turn affects the postoperative recovery of hip joint function. The impact of impaction fractures on functional recovery is more significant in patients aged 50 years and above.

Objective:To investigate the expression of nuclear matrix protein 4 (NMP4) in hepatocellular carcinoma (HCC), and its relationship with clinicopathological features and survival prognosis of patients.Methods:The clinical data of 100 HCC patients who were treated with radical resection of liver cancer in the Department of Hepatobiliary Surgery of the Third Affiliated Hospital of Wenzhou Medical University from July 1, 2014 to July 1, 2019 were retrospectively analyzed. There were 63 males and 37 females, aged (58.5±10.4) years old. Immunohistochemical method was used to detect the expression of NMP4 protein in HCC cancer tissue and the corresponding adjacent normal tissue. According to the expression of NMP4 in HCC tissues, 100 patients were divided into two groups: the NMP4-positive expression group ( n=62) and the NMP4-negative expression group ( n=32). Univariate analysis was performed on the relationship between NMP4 expression and clinical pathological features as well as overall survival of HCC patients. Cox multivariate analysis was performed on the factors influencing postoperative prognosis of HCC patients. Results:Immunohistochemistry results showed that NMP4 was primarily expressed in the nucleus, the positive expression rate of NMP4 in HCC tissues was higher than that in adjacent non-cancerous tissues [62.0% (62/100) vs. 8.0%(8/100)], and the difference was statistically significant ( χ2=2.12, P=0.003). Univariate analysis revealed that the overall survival of HCC patients was correlated with the degree of tumor differentiation, tumor length, BCLC stage, number of tumor foci, vascular tumor thrombus and expression of NMP4 (all P<0.05). Cox multivariate analysis revealed that low differentiation, high BCLC stage (stage C), number of tumor foci (≥3), and positive expression of NMP4 were independent risk factors affecting postoperative survival and recurrence-free survival of HCC patients. The median overall survival and median recurrence-free survival of HCC patients in the NMP4-positive expression group were 22.3 months and 11.5 months, respectively. In contrast, that in the NMP4-negative expression group were 40.6 months and 19.4 months, respectively. The cumulative survival rate and recurrence-free survival rate of HCC patients in the NMP4-positive expression group were lower than those in the NMP4-negative expression group, and the differences were statistically significant (both P<0.05). Conclusion:Positive NMP4 expression was closely correlated with malignant biological progression and poor prognosis of HCC patients.

Objective To study the clinical and CT findings of bronchiolar adenoma. Methods Patients diagnosed with bronchiolar adenoma confirmed by surgical pathology at Linyi People's Hospital and Yantai Yuhuangding Hospital from 2016 to 2021 were collected. Their clinical and CT imaging features were retrospectively analyzed. Results Finally, 25 patients were collected, including 6 males and 19 females, aged 32-73 (58.6±10.1) years. The immunohistochemical Ki-67 (MIB1) of all lesions was <5%. The lesions were located in the upper and middle lobe of both lungs in 9 patients, lower lobes in 16 patients, extrapulmonary zone in 22 patients, intrapulmonary middle zone in 3 patients, round in 11 patients, irregular in 14 patients, well-defined in 22 patients, pure ground-glass/mixed ground-glass nodules in 6 patients, solid nodules in 19 patients. There were 11 patients with central small cavity, 18 patients with single bronchioles sign, 19 patients without adhesion with adjacent pleura, and 24 patients without mediastinal lymph node enlargement. Conclusion Bronchiolar adenomas usually occur in the middle-aged and elderly, mostly in the lower lobe of both lungs and the distribution of the peripheral lung field, most of the patients do not have any clinical symptoms, and the postoperative prognosis is good. CT may show large nodules or masses, pure ground-glass/mixed ground-glass nodules, irregular solid nodules and central small cavities. Irregular stellate nodules, central small cavity shadow, and single bronchiolar vascular bundle connected with the lesions are relatively specific imaging findings of bronchiolar adenoma.

Objective:To study the correlation between zinc finger protein A20 (A20) and basic fibroblast growth factor (BFGF) and liver fibrosis in chronic hepatitis B.Methods:A retrospective study was conducted to select 120 patients with chronic hepatitis B diagnosed and treated in the Fifth Hospital of Shijiazhuang City from January 2019 to December 2020, all of whom underwent liver tissue biopsy, and 25 cases of liver pathological specimens who underwent liver hemangioma resection were selected. The correlation between the expression of A20 and BFGF in liver tissue and the stage of hepatic fibrosis and inflammation were analyzed.Results:The expression of A20 in the S1 - S4 phase was higher than that in the S0 phase: (6.12 ± 1.22)%, (10.18 ± 2.43)%, (16.94 ± 5.06)%, (25.99 ± 7.57)% vs. (0.81 ± 0.29)%; the expression of BFGF in the S1 - S4 phase was higher than that in the S0 phase: (6.12 ± 1.22)%, (10.18 ± 2.43)%, (16.94 ± 5.06)%, (25.99 ± 7.57)% vs. (0.81 ± 0.29)%, there were statistical differences ( P<0.05). The expression of A20 in the G1 - G4 phase was higher than that in the G0 phase: (6.56 ± 1.87)%, (10.01 ± 3.29)%, (15.54 ± 5.01)%, (25.86 ± 8.02)% vs. (0.85 ± 0.71)%; the expression of BFGF in the G1 - G4 phase was higher than that in the G0 phase: (5.91 ± 1.52)%, (9.65 ± 2.48)%, (15.03 ± 4.86)%, (24.62 ± 7.22)% vs. (0.79 ± 0.41)%, there were statistical differences ( P<0.05). The results of Pearson test showed that there was a positive correlation between liver A20 and BFGF ( r = 0.824, P<0.05). Conclusions:The expressions of A20 and BFGF in liver tissue increase with the aggravation of liver pathological fibrosis and inflammation, which can be used as important indicators to evaluate the severity of liver fibrosis.

Objective:To explore the application effect of early nursing intervention based on NNN-link in social disorders of children with autism spectrum disorders (ASD) .Methods:A total of 126 hospitalized children with ASD in the Rehabilitation Center of Henan Children's Hospital from January to May 2023 were selected as research subjects by convenience sampling. They were randomly divided into an intervention group ( n=63) and a control group ( n=63) using a random number table. The control group received routine care, while the intervention group received early nursing intervention based on NNN-link in addition to routine care. The Social Disorder-related Nursing Diagnosis Outcome Scales and the Childhood Autism Rating Scale (CARS) scores were compared between the two groups before and after intervention. Results:After the early nursing intervention, the scores for family atmosphere, participation in leisure activities, participation in play, social skills, and social participation were higher in the intervention group compared to the control group, the differences were statistically significant ( P<0.05). The CARS scores of the intervention group were also lower than those of the control group, the differences were statistically significant ( P<0.05) . Conclusions:Early nursing intervention based on NNN-link can effectively improve the social disorder conditions of children with ASD, reduce their autism symptoms, and promote recovery.

Objective:To explore the feasibility and consistency of a new digital classification system of pelvic fractures named as JST classification based on close reduction techniques.Methods:A retrospective collection was conducted of the data from the 63 patients with pelvic fracture who had undergone surgical treatment after JST classification at Department of Orthopaedics and Traumatology, Beijing Jishuitan Hospital from March 2021 to March 2023. Digital classification of the pelvic fractures was performed based on their locations and displacements. The classification first divides the pelvis into 4 parts: left half pelvis and right half pelvis; sacral Denis Ⅲ area and pubic symphysis. The symmetrical left and right sacral Denis Ⅰ and Denis Ⅱ areas are also included in the left/right half pelvis. Subsequently, the left half pelvis and right half pelvis are divided into 4 regions and marked by capitalized English letters: Sacrum Area (including Denis Ⅰ and Denis Ⅱ, denoted as S), Sacroiliac Joint Area (denoted as J), Iliac Area (denoted as I), and Pubic Area (denoted as P); to distinguish right/left, R and L are used as prefixes. The 2 asymmetric parts are also marked with English letters: Denis Ⅲ area of the sacrum (denoted as Sac), and pubic symphysis (denoted as C). Afterwards, the fracture line morphology and displacement in each region are marked digitally to form a complete JST classification system. The inter- and intra-observer reliabilities (Fleiss' and Cohen's Kappa) of the JST classification system were tested by 3 observers with more than 10 years of experience in pelvic fracture treatment.Results:Consistency analysis of the JST classification results showed that the mean κ value of the intra-observer reliability was 0.818 (from 0.658 to 0.946, P<0.001) and the inter-observer reliability 0.873 (from 0.674 to 1.000, P<0.001), both indicating excellent agreement. Of the 63 patients, 59 obtained successful closed reduction with the assistance of the Rossum Robot R-Universal intelligent orthopedic surgical robot system after fracture classification by the JST system, yielding a success rate of 93.7% (59/63). Conclusions:The new JST classification system for pelvic fractures demonstrates strong intra and inter-observer reliabilities compared with traditional classification systems. As JST classification system labels each fracture site and key bones, it is of great significance for the deep learning and intraoperative operations of intelligent fracture robots.

Objective:To investigate the expression characteristics of mucin 5B (MUC5B) protein and programmed cell death factor 4 (PDCD4) protein in patients with intrahepatic cholangiocarcinoma (ICC), and to construct a nomogram model for prognosis prediction.Methods:Clinical data of 100 patients who underwent radical surgical resection and were diagnosed as ICC by postoperative pathology from September 2009 to September 2020 in the Third Affiliated Hospital of Wenzhou Medical University were retrospectively selected, including 46 males and 54 females, aged (56.9±12.2) years old. Immunohistochemistry was used to detect the expression of MUC5B and PDCD4 protein in 100 cases of ICC and corresponding adjacent tissues respectively, and the relationship between them and clinicopathological factors of ICC patients was analyzed. Univariate and multivariate Cox regression analysis were performed to analyze the influencing factors on postoperative prognosis of ICC patients. The nomogram model was constructed using rms package and performed internal verification.Results:The positive expression rate of MUC5B protein in ICC was 76.0% (76/100), which was higher than that in para-cancer tissues 27.0%(27/100), and the difference was statistically significant ( χ2=11.33, P=0.015). While the positive expression rate of PDCD4 protein in ICC was 21.0%(21/100), which was lower than that in normal tissues 73.0% (73/100), and the difference was statistically significant ( χ2=15.57, P=0.007). Multivariate Cox regression analysis showed that ICC patients with carbohydrate antigen 19-9>37 kU/L, tumor length>5 cm, tumor TNM stage Ⅱ/Ⅲ, tumor medium/low differentiation, MUC5B positive expression, and PDCD4 negative expression had a high risk of short survival after resection (all P<0.05). The nomogram model was constructed based on the above indicators, and the C-index was 0.801. The postoperative survival calibration curve showed that the high predictive survival fit of the nomogram model, and the area under the receiver operating characteristic curve was 0.862. Conclusions:Positive expression of MUC5B protein and negative expression of PDCD4 protein in ICC tissue suggest poor prognosis of ICC patients. The nomogram model constructed on the basis of MUC5B and PDCD4 protein is well distinguished and has ideal predictive efficacy.

In recent years，with the change in lifestyle and social environment and the increase in pressure in both life and work，male fertility has decreased significantly in China，and the incidence of male infertility has increased year by year，which has brought great challenges to andrologists. Traditional Chinese medicine （TCM） has a definite curative effect in the treatment of male infertility and is widely applied in clinical practice. In order to clarify the role of TCM in different types and each stage of male infertility，the China Association of Chinese Medicine （CACM） invited outstanding young andrologists in the clinic of TCM and western medicine to discuss topics such as idiopathic oligospermia and teratospermia，abnormal semen liquefaction，varicocele，immune infertility，improving success ratio of assisted reproductive technology，and ameliorating depression or anxiety. They conducted in-depth discussions on the advantages，characteristics，disadvantages，diseases responding specifically，and advantageous aspects of TCM treatment. The causes of male infertility and related links of treatment were summarized. Due to the unclear etiology and complex pathogenesis of male infertility，western medicine cannot achieve a good curative effect，while TCM，taking the holistic view as the core，specializes in improving functional diseases and can correspond to multiple targets and factors，with comprehensive treatments such as internal treatment and external treatment. This study summarized the advantageous diseases and advantageous stages of TCM treatment alone and integrated TCM and western medicine treatment and put forward suggestions for the treatment of the diseases by TCM and western medicine in order to promote the therapeutic effects and advantages of TCM among andrologists，increase mutual learning and communication between TCM and western physicians，provide patients with excellent and personalized treatment plans in clinical practice，and improve the curative effect of male infertility and fertility of males in China.

Aortic dissection, especially Stanford type A aortic dissection, is an acutely progressive and highly fatal cardiovascular disease.Early prevention and timely treatment can greatly reduce mortality and reduce the burden on families and society.However, due to the etiological mechanism is still unclear, the clinical treatment is still mainly surgery, and the early prevention and drug application are very limited.And some recent studies have found that ferroptosis may play an important role in the occurrence and development of aortic dissection, revealing the relationship between them may provide ideas for the prevention, treatment and scientific research of the disease.
