Stroke is the leading cause of death and disability among adults in China， and its common complications include digestive system abnormalities， cognitive impairment， depression， stroke-associated pneumonia， and hemiplegia. The combination of traditional Chinese and Western medicine has great potential in treating post-stroke complications. Xinglou Chengqitang （XLCQT） is a representative prescription of alleviating the disease in the upper part by treating the lower part. It has definite therapeutic effect and high safety. Clinically， XLCQT is often used to treat stroke and its complications. However， the quantity and quality of clinical trials of XLCQT in treating post-stroke complications need to be improved. Additionally， since the basic research is weak， the material basis and multi-target mechanism for the efficacy of this prescription are unknown. This article reviews XLCQT in terms of the pharmacodynamic basis， medicinal properties， safety evaluation， and progress in clinical research and mechanisms in treating post-stroke complications. This article summarizes 22 key active ingredients of XLCQT in treating acute stroke complicated with syndrome of phlegm heat and fu-organ excess. Among these key active ingredients， resveratrol， kaempferol， luteolin， chrysoeriol， apigenin， （+）-catechin， and adenosine have good pharmacokinetic properties and high bioavailability. The mechanisms of XLCQT in treating post-stroke complications are complex， including inflammatory response， brain-gut axis， hypothalamic-pituitary-adrenal （HPA） axis， intestinal flora， neurotrophic factors， autophagy， oxidative stress， and free radical damage. This review helps to deeply understand the pharmacodynamic basis and mechanisms of XLCQT in treating post-stroke complications and provides a theoretical basis for the clinical application of XLCQT against post-stroke complications and the development of drugs.

ObjectiveTo investigate the effect of the multidisciplinary team （MDT） management model in improving the prognosis of patients with cirrhotic portal hypertension. MethodsA total of 86 patients with cirrhotic portal hypertension who were admitted to Shenzhen Third People’s Hospital from May 2022 to July 2024 were enrolled， and according to whether the MDT treatment regimen was implemented， they were divided into execution group with 51 patients and non-execution group with 35 patients. Baseline clinical data were collected， and the patients were observed in terms of gastrointestinal bleeding， hepatic encephalopathy， liver cancer， and death from admission to the end of follow-up （January 2025）. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Wilcoxon rank-sum test was used for comparison of non-normally distributed continuous data between two groups； the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups. The Kaplan-Meier method was used to plot survival curves for the cumulative incidence rates of endpoint events （gastrointestinal bleeding， hepatic encephalopathy， liver cancer， and death）， and the Log-rank test was used for comparison between groups. The Cox proportional-hazards regression model analysis was used to investigate the effect of MDT management on the prognosis of patients. ResultsThere were significant differences between the execution group and the non-execution group in diameter of the portal vein （t=1.216， P=0.017） and ascites （χ²=4.515， P=0.034） at baseline. The patients were followed up for 14.6±6.2 months， and the survival curve analysis showed that there was a significant difference in the cumulative incidence rate of gastrointestinal bleeding between the two groups （χ²=4.573， P=0.024）， while there were no significant differences in the incidence rates of other outcome events between the two groups （all P>0.05）. The Cox regression analysis showed that the execution group had a reduced risk of gastrointestinal bleeding （hazard ratio=0.262， 95% confidence interval： 0.110 — 0.630， P=0.003）. ConclusionImplementation of the MDT treatment regimen can significantly reduce the short-term risk of gastrointestinal bleeding in patients with cirrhotic portal hypertension， while its long-term benefits require further follow-up verification.

Objective:To explore the characteristics of SMN1 gene variants and carry out functional verification for two children with Spinal muscular atrophy (SMA). Methods:Two male children with complicated SMA diagnosed at the Children′s Hospital Affiliated to Capital Institute of Pediatrics respectively in July 2021 and April 2022 due to delayed or retrograde motor development were selected as the study subjects. Clinical data of the children were collected. Primary culture of skin fibroblasts was carried out, and peripheral blood samples were collected from both children and their parents. Multiplex ligation-dependent probe amplification, combined long-range PCR and nested PCR, and Sanger sequencing were carried out to detect the copy number and variants of the SMN1 gene. Absolute quantitative real-time PCR, Western blotting and immunofluorescence were used to determine the transcriptional level of the SMN gene, expression of the SMN protein, and the number of functional SMN protein complexes (gems body), respectively. This study was approved by Medical Ethics Committee of the Children′s Hospital Affiliated to Capital Institute of Pediatrics (Ethics No. SHERLLM2021009). Results:Child 1, a 1-year-old boy, was clinically diagnosed with type 1 SMA. Child 2, a 2-and-a-half-year-old boy, was clinically diagnosed with type 3 SMA. Both children were found to harbor a paternally derived SMN1 deletion and a maternally derived SMN1 gene variant, namely c. 824G>T (p.Gly275Val) and c. 884A>T (p.*295Leu). Compared with the normal controls and carriers, the levels of full-length SMN1 transcripts in their peripheral blood and skin fibroblast cell lines were significantly decreased ( P<0.05), and the levels of SMN protein normalized to that of β-actin, and the numbers of gems bodies in the primary fibroblast cells were also significantly lower ( P<0.05). Based on the guidelines from the American College of Medical Genetics and Genomics, both variants were classified as likely pathogenic (PS3+ PM3+ PM5+ PP3; PS3+ PM3+ PM4+ PP3). Following the diagnosis, both children had received nusinersen treatment. Although their motor function was improved, child 1 still died at the age of 2 due to severe pulmonary infection. The walking ability of child 2 was significantly improved, and his prognosis appeared to be good. Conclusion:Two cases of clinically complicated SMA have been confirmed by genetic testing and experimental studies, which has provided a reference for their accurate treatment.

Objective:To explore the distribution of the copy number of survival motor neuron gene 2 ( SMN2) and the transcript level of the full-length SMN2 ( fl-SMN2) transcript level in patients with type 1-3 spinal muscular atrophy (SMA), and to evaluate their influences on disease severity, progression, and prognosis. Methods:It was a retrospective study involving 78 therapy-naive SMA patients with SMN1 gene homozygous deletion who were diagnosed and treated in the Capital Institute of Pediatrics from January 2019 to December 2021.Cross-sectional clinical data, including age at onset, motor milestones, and complications were recorded.They were followed up for monitoring motor function degeneration and survival.The copy number of SMN2 and the transcript level of fl-SMN2 were detected.Differences between groups were compared by the Student′s t-test or One- Way ANOVA or Chi- square test.Kaplan-Meier analysis was used for survival analysis, and Kendall′ s tau- c was performed to assess the correlation of these two biomarkers with SMA phenotypes, age at onset, motor milestones, and survival. Results:Of the 78 SMA patients, there were 17 cases (21.8%) of type 1, 34 cases(43.6%) of type 2, and 27 cases(34.6%) of type 3.Seven cases(41.2%) type 1 SMA patients died, with a median survival time of 11 months, and no deaths were observed in type 2 and type 3 SMA patients.There was a significant difference in the median age at onset among SMA patients with 2, 3, and 4 copies of SMN2 (1.8, 12.0, and 24.0 months, respectively; F=4.943, P=0.01). The mean transcript level of fl-SMN2 in type 1, 2 and 3 SMA patients were 196.25±68.79, 331.21±108.79 and 455.69±122.27, respectively ( F=37.154, P<0.001). The survival rate of SMA with 2 SMN2 copies at 1, 2, and 5 years were 50.5%, 0, and 0, respectively, and their median survival age was 7 months.The survival rate of SMA with 3 and 4 SMN2 copies at 5 years were 97.4% and 100.0%, respectively.Moreover, a negative correlation was observed between the transcript level of fl-SMN2 and phenotype severity ( Kendall′ s tau- c=-0.444, P<0.001), and the transcript level of fl-SMN2 of the survival group was much higher than that of the death group (342.93±125.74 vs.212.14±92.31). More copies of SMN2 and higher transcript level of fl- SMN2 indicated more motor function acquisitions (head control, sitting and walking) ( P<0.001). In addition, there was a significant difference in the transcription level of fl-SMN2 between the undegenerated group and the degenerated group in sitting and standing ( F=5.432, P=0.023 and F=4.315, P=0.047, respectively). Conclusions:Both the copy number of SMN2 and the transcript level of fl-SMN2 are correlated with SMA severity, survival, and motor milestones, serving as valuable biomarkers for evaluating phenotypic severity of SMA.The transcript level of fl-SMN2 s may play an important role in the degeneration of sitting and standing.

Objective:To evaluate the 5-year survival outcome of patients with unresectable locally advanced non-small cell lung cancer (NSCLC) treated with Endostar in combination with platinum-based concurrent chemoradiotherapy.Methods:From March 2009 to June 2015, 115 patients with the unresectable locally advanced NSCLC from two prospective studies[Clinical trials 2009-2012(ClinicalTrials.gov NCT01894) and 2012-2015(ClinicalTrials.gov, NCT01733589)] were treated with Endostar in combination with platinum-based concurrent chemoradiotherapy. A total dose of 60-66 Gy was delivered in 30-33 fractions. Endostar was given 1 week prior to the beginning of radiotherapy, and repeated fortnightly during the concurrent chemoradiotherapy. After long-term follow up, survival outcome was evaluated in 104 patients treated with radiation dose of ≥60 Gy. Kaplan-Meier method was used for survival analysis. Univariate survival analysis was performed using the log-rank test.Results:Of 104 eligible patients, 60.6% of them had squamous carcinoma and 65.4% were classified in stage Ⅲ B. All the patients received ≥2 cycles of Endostar and 93.3% of them received 4 cycles of Endostar. The median follow-up time was 68.3 months. The median overall survival (OS) and median progression-free survival (PFS) were 31.3 and 13.9 months, respectively. The 3-year and 5-year OS were 45.6% and 35.7%, respectively. The 3-year and 5-year PFS were 27.1% and 24.9%, respectively. Univariate analysis indicated that sex, ECOG, pathological type, clinical stage, radiotherapy technique, chemotherapy regimen, chemotherapy cycle and cycle of Endostar use were not associated with OS. Late radiation injury occurred in 14.4% of patients, and no grade 4-5 late injury was observed. Conclusion:Patients with unresectable locally advanced NSCLC treated with Endostar fortnightly in combination with platinum-based concurrent chemoradiotherapy achieve better OS than historical data with tolerable toxicities.

Objective:To explore application status and development trend of spinal muscular atrophy (SMA) genetic diagnosis technology based on the national rare diseases registry system of China.Method:A total of 200 SMA children registered at the Capital Institute of Pediatrics from July 2016 to December 2018 were included in this retrospective cross-sectional survey. The basic data, clinical subtypes, genotypes, and related genetic testing information of SMA children were obtained by checking SMA registration information, genetic testing reports, and also by telephone follow-up. The patient number and the composition of different genetic diagnosis technologies were analyzed by the stratification of genetic testing at various time. The correlation between the proportion of genetic diagnosis technology and genetic testing time was analyzed with Pearson correlation analysis.Result:There were 3 SMA cases with incomplete data, the remaining 197 SMA cases were included in this study. There were 37 (18.8%), 115 (58.4%) and 45 (22.8%) patients with type Ⅰ, Ⅱ and Ⅲ SMA, respectively. There were 185 cases of SMN1 homozygous deletion (93.9%), and 12 cases with compound heterozygotes (6.1%). Seven SMA-related genetic technologies were used from 2004 to 2017. MLPA accounted for 54.1% (100/185) used approach, followed by PCR-RFLP and first-generation sequencing, which accounted for 22.7% (42/185) and 10.3% (19/185), respectively. Nine, 6, 5 and 4 cases were tested with AS-PCR, qPCR, WES and DHPLC, respectively (2.2%-4.9%). The proportion of MLPA increased gradually since 2010 ( r=0.95, P<0.05), while PCR-RFLP declined gradually since 2004 ( r=-0.99, P<0.05). No correlation was found between technology and testing time for other genetic testing technologies ( P>0.05). The proportion of quantitative genetic technologies (MLPA, qPCR and DHPLC) increased gradually since 2010 ( r=0.94, P<0.05), and qualitative genetic technologies (PCR-RFLP, first-generation sequencing, AS-PCR and WES) decreased gradually since 2004 ( r=-0.94, P<0.05). The duplication detection rates of homozygous deletion and compound heterozygous mutation were 12.4% (23/185) and 41.7% (5/12), respectively (χ 2=5.86, P<0.05). During 2008-2015, the proportion of "the reports of both copy numbers of SMN1 gene and SMN2 gene" increased from 56.8% (21/37) in 2008-2015 to 69.1% (56/81) in 2016-2017. Conclusion:Genetic diagnosis of SMA has gradually developed from qualitative detection technology to quantitative detection technology, such as MLPA and qPCR, in China. In more and more SMA quantitative test reports, quantitative results of SMN2 gene are also provided in addition to quantitative results of SMN1 gene.

Objective:To analyze the feasibility of hippocampal-avoidance (HA) prophylactic cranial irradiation (PCI) in small cell lung cancer patients (SCLC)(limited stage) after chemotherapy and thoracic radiation.Methods:From June 2016 to March 2019, 40 eligible SCLC patients were recruited and randomly divided into the routine PCI ( n=22) and hippocampal-avoidance PCI (HA-PCI) groups ( n=18). The HA zone was contoured according to the criteria of RTOG 0933. Volumetric-modulated arc therapy (VMAT) was adopted in the HA-PCI group. After radiotherapy, Hopkins verbal learning test (HVLT) and MRI were performed. Results:The average hippocampus volume was (4.01±1.57) cm 3, the average HA volume was (20.13±4.14) cm 3, HA D 100% was (7.19±0.38) Gy and HA D max was (14.38±1.18) Gy. During HVLT, 1-month-after-PCI vs. before-PCI (trial3, trial4, learning, percent retained), 1-month-after-PCI vs. after-PCI (trial3, learning), HA-PCI cohort showed advantages over PCI in HVLT scores. The average follow-up time was (17.00±8.47) months. Two patients with brain metastases which were out of the HAZ received routine PCI. Conclusions:PCI using VMAT technology to protect hippocampus is feasible in dosimetry. The test results indicate that the protective effect of hippocampus protection on memory is worthy of further promotion in clinical practice.

Objective:To investigate the coverage rate and the adverse reactions of National Immunization Program vaccines in children with spinal muscular atrophy (SMA).Methods:A cross-sectional retrospective cohort study was carried out from July 2016 to June 2019, 192 children (116 boys and 76 girls) with SMA registered by Capital Institute of Pediatrics and 191 healthy children (115 boys and 76 girls) vaccinated in Chaoyang Olympic Village Community Health Service Center from July 2016 to December 2018 were included. Questionnaire survey was designed to investigate the vaccination coverage rate and associated adverse events. The t-test and χ 2 test were used to compare the difference between SMA patients and healthy children. Results:The coverage rate of age-appropriate immunization in SMA children was 62.0% (119/192) in general, and were 52.2% (12/23), 55.7% (68/122), and 83.0% (39/47) for SMA type 1-3 patients, respectively (χ 2=12.23, P=0.002). The vaccination coverage rates of Bacillus Calmette-Guerin (BCG) vaccine, the 3 rd dose of hepatitis B, the 3 rd dose of polio, the 3 rd dose of diphtheria-pertussis-tetanus, the 1 st dose of meningococcal polysaccharide group A, the 1 st dose of measles or measles and rubella vaccine, the 1 st dose of Japanese encephalitis vaccine, hepatitis A, measles-mumps-rubella, and group A+C meningococcal polysaccharide vaccine were 100.0% (192 cases), 94.3% (181 cases), 81.8% (157 cases), 88.5% (170 cases), 83.9% (161 cases), 76.6% (147 cases), 80.2% (154 cases), 68.2% (131 cases), 69.8% (134 cases), 54.7% (105 cases), respectively. Among the 73 patients who did not have their planned immunization completed, 57 cases (78.1%) gave up the vaccination due to parents′ concern of potential aggravation of their disease, and 16 cases (21.9%) had the plan discontinued by the immunization department because of the disease. Fever, local redness and swelling were the most common side-effects after vaccination both in SMA patients and healthy children (19.8% (38/192) vs. 18.8% (36/191) , χ 2=0.055, P=0.815). The main abnormal reactions of vaccination were rash and neurovascular edema, without significant difference between these two groups (2.6% (5/192) vs. 3.7% (7/191), χ 2=0.355, P=0.551). The coverage rate of Influenza and pneumococcal vaccine in SMA patients were 22.4% (43 cases) and 31.8% (61 cases), respectively. The incidence of pneumonia in the SMA patients decreased from 59.0% (23/39) to 41.0% (16/39) after vaccination. And none of the Influenza vaccinated patients had the flu in the year of vaccination. Conclusions:The coverage rate of National Immunization Program vaccines in the SMA children is low, especially in type 1 SMA patients, which is mainly due to their guardians′ concern of potential adverse events, even though the incidence of adverse reactions is similar in SMA patients and healthy children. Influenza and pneumococcal vaccine can reduce the risk of pneumonia and flu in children with SMA effectively.

Objective:To analyze the effect of comprehensive health management on the prognosis of children with type Ⅰ spinal muscular atrophy (SMA).Methods:Eighty patients with type Ⅰ SMA (39 males and 41 females) visited-Capital Institute of Pediatrics from January 2003 to December 2017, were enrolled in this case-control study retrospectively. They were divided into the health management group and the natural history group. Main statistical parameter, including demographic indicators, survival time, 2-year survival rate and incidence of complications were compared and analyzed. Patients were evaluated every 3-6 months. All data were processed by SPSS 19.0. Differences between the two groups were compared using rank sum test or chi square test. Survival analysis was performed by using Kaplan-Meier method, and survival difference test was performed by log-rank method.Results:Among 80 SMA patients, 14 cases (7 males and 7 females) were in the health management group and 66 cases (32 males and 34 females) in the natural history group. There was no statistically significant difference in gender ratio between the two groups (χ 2=0.01, P=0.918) . The ages of onset and death in the two groups were 2 (0-8) and 1 (0-14) month, 11 (5-17) and 6 (1-60) months, without statistically significant difference ( Z=0.91, 1.19; P=0.386, 0.116) . As of the follow-up date (June 2019) , 10 patients died and 4 survived in the health management group, while 62 (93.9%) died and 4 (6.1%) survived in the natural history group (χ 2=6.50, P=0.011) . The median survival time in the health management group was 12 months, and the 1, 2 and 3-year survival rates were 77.9%, 54.5% and 34.1%, respectively. The median survival time of the natural history group was 6 months, and the 1, 2 and 3-year survival rates were 48.5%, 15.2% and 7.6%, respectively. For the two groups, the difference in survival rates was statistically significant (χ 2=9.11 P=0.003). The incidence rate of pneumonia combined with respiratory failure in the health management group was lower than that in the natural history group. Conclusion:Active health management can improve the survival rate of type Ⅰ SMA patients, reduce the incidence of complications, and also improve the prognosis of patients.
