This article systematically analyzes the historical evolution of the name， medicinal parts， origin， harvesting， processing and other aspects of Houttuyniae Herba（HH） by referring to the medical books， prescription books and other documents of the past dynasties， combined with the research materials related to modern and contemporary times， in order to provide a basis for the development of famous classical formulas containing this herb. In ancient literature， HH was often referred to as "Ji" and "Jicai"， the name of "Ji" was first recorded in Mingyi Bielu during the Han and Wei dynasties， and the name of Yuxingcao was first seen in Lyuchanyan Bencao during the southern Song dynasty and has continued to this day. The origin of HH used throughout history is consistent， all of which are the whole herb or aboveground parts of Houttuynia cordata in Saururaceae family. HH recorded throughout history has a wide range of production areas， mostly self-produced self-marketing. In ancient times， fresh HH was often used as medicine by pounding its juice without involving any processing steps. Both fresh and dried products can be used as medicine， the fresh products uses the whole plant， while the dried products uses the aboveground parts， which are cleaned， selected and processed before use. Fresh products are harvested regardless of season， while dried products are harvested in both summer and autumn， with summer as the best. In ancient times， there were no specific requirements for the quality of HH， while in modern times， "intact stems and leaves with a strong fishy smell" are preferred. In addition， the medicinal properties of HH have undergone significant changes from ancient to modern times. In the early period， it was believed that its medicinal property was slightly warm， until the 1977 edition of Chinese Pharmacopoeia officially changed it to slightly cold. Both ancient and modern literature states that HH can be used for the treatment of carbuncle and malignant sores， Lyuchanyan Bencao for the first time introduced HH fresh juice can relieve summer heat， since Diannan Bencao recorded that it can be used for lung carbuncle， and gradually developed into the first choice for the treatment of lung carbuncle. Based on the research results， it is suggested that fresh herb or dried aboveground parts of H. cordata are used as medicine when developing famous classical formulas.

Objective To investigate clinical effect of tendons pulling,poking and kneading for the treatment of external humeral epicondylitis.Metods From January 2018 to December 2021,a multicenter randomized controlled study was per-formed to collect 192 patients with external humeral epicondylitis in Wangjing Hospital,Beijing Dianli Hospital,and Beijing Fengsheng Osteotraumatology Hospital,respectively,and they were divided into treatment group and control group by random number table method.There were 96 patients in treatment group,including 36 males and 60 females,aged from 28 to 60 years old with an average of(41.20±5.50)years old;the course of disease ranged from 1 to 14 days with an average of(5.24±1.35)days;they were treated once every other day for 2 weeks.There were 96 patients in control group,including 33 males and 63 females,aged from 26 to 60 years old with an average of(43.35±7.75)years old;the course of disease ranged from 1 to 14 days with an average of(5.86±1.48)days;they were treated with topical voltaalin combined with elbow joint fixation for 2 weeks.Visual analogue scale(VAS)and Hospital for Surgery Scoring System(HSS)elbow pronation and supination angles,wrist metacarpal flexion and dorsal extension angles,elbow tenderness between two groups were compared before treatment and at 1,3,5,7,11 and 13 days after treatment;Hospital for Surgery Scoring System 2(HSS2)was compared before treatment and the final treatment.Results All patients were followed up for 10 to 14 days with an average of(12±1.6)days.VAS between treatment group and control group before treatment were 6.83±1.36 and 6.79±1.58,respectively,and decreased to 1.49±1.09 and 2.11±1.81 after the final treatment.VAS of treatment group were significantly lower than those of control group at 1,3,5,7,9,11 and 13 days after treatment(P＜0.05).HSS between two groups were 61.73±11.00 and 36.47±12.45 before treatment,respectively,and increased to 94.42±5.9 and 91.44±9.11 at the final treatment.HSS of treatment group were signifi-cantly higher than those of control group at 1,3,5,7,9,11 and 13 days after treatment(P＜0.05).On the 5th day after treat-ment,the external and internal rotation angles of elbow in treatment group were(66.41±12.69)° and(66.35±13.54)°,while those in control group were(62.08±16.03)° and(61.77±16.35)°.On the 7th day after treatment,the external and internal ro-tation angles of elbow were(69.79±12.64)° and(70.02±13.55)° in treatment group,and(65.28±15.86)° and(65.09± 16.67)° in control group.Elbow joint motion in treatment group was higher than that in control group(P＜0.05).On the 5th day after treatment,angles of wrist dorsiflexion and palm flexion were(39.43±15.94)°and(46.68±11.10)° in treatment group,and(38.51±18.49)° and(44.27±13.58)° in control group.On the 7th day after treatment,angles of wrist dorsiflexion and palm flexion were(42.52±16.50)° and(49.23±10.96)° in treatment group,and(41.18±20.09)° and(46.64±14.63)° in control group.The motion of wrist joint in treatment group was higher than that in control group(P＜0.05).On the 13th day after treatment,HSS2 in treatment group 93.61±6.32 were higher than those in control group 92.06±7.94(P＜0.05).There was no significant difference in elbow tenderness between two groups at each time point(P＞0.05).Conclusion Voltaren external treatment combined with elbow fixation and tendons pulling,poking and kneading could effectively improve symptoms of exter-nal humeral epicondylitis.Compared with voltaren external treatment,tendons pulling,poking and kneading has advantages of longer analgesic time and better elbow function recovery.

Objective To investigate the clinical efficacy and safety of single-port thoracoscopic surgery for elderly patients with non-small cell lung cancer(NSCLC).Methods The clinical data of 93 patients with NSCLC who underwent thoracoscopic lobectomy or segmentectomy was collected,the patients were divided into uniportal operation group(40 cases,received single-port thoracoscopic surgery)and single-operation port operation group(53 cases,received single-operation port thoracoscopic surgery)according to the operation methods.The operation time,the amount of blood loss,the number of lymph node dissection,chest drainage volume 3 days after surgery,duration of indwelling drainage tube,postoperative hospital stay,visual analogue scale(VAS)score of postoperative pain,and incidence of postoperative complications of patients between the two groups were compared.The cumulative survival rate between the two groups was compared.Results The operation were successfully completed in both groups.There was no statistically significant difference in terms of operation time,the amount of blood loss,the number of lymph node dissection,chest drainage volume 3 days after surgery,duration of indwelling drainage tube,or postoperative hospital stay of patients between the two groups(P>0.05).There was significant difference in VAS score of postoperative pain of patients between the two groups(P<0.05).There was no early death within 1 months after surgery in both groups.There was no significant difference in the incidence of complications between the two groups(P>0.05).After 4 to 30 months of follow-up,there was no significant difference in the cumulative survival rate between the two groups(P>0.05).Conclusion Single-port thoracoscopic lobectomy or segmentectomy for elderly patients with NSCLC has high safety and feasibility,with less trauma,faster recovery and less postoperative pain.

Post-stroke cognitive impairment(PSCI)is a common complication after stroke,which significantly affects quality of life.However,the pathogenesis has not been fully explained.Increasing evidence has shown that the mechanism of programmed cell death(PCD)is related to PSCI,including apoptosis,necroptosis,pyroptosis,PANoptosis,parthanatos,and ferroptosis.Therefore,it is crucial to clearly understand the various mechanisms of PCD and their relationship with PSCI,and to elucidate the role of PCD in PSCI pathogenesis.The article reviews six PCD pathways related to PSCI,summarizes their mechanisms of action in PSCI,and elucidates the possible crosstalk among pathways to provide a basis for clinical targeting of regulatory factors in the PCD pathway for PSCI treatment.

Objective:To assess the deformation of the bladder-neck opening and the impact of the bladder-neck angle(BNA)on urination in male patients by fluid-structure interaction(FSI)analysis.Methods:We established geometric models of the blad-der,prostate and urethra were established,incorporating both normal and enlarged BNAs,and assessed the effects of BNA alteration on urinary flow by FSI simulation of the flow rate and pressure of the urine within the bladder,bladder neck and urethra,and that of pros-tate displacement as well.We retrospectively analyzed the clinical data on 145 male patients from the Second Hospital of Hebei Medical University between June 2020 and June 2023,39 with acute urine retention(the AUR group)and 106 without(the non-AUR group),and evaluate the impact of BNA on urination based on the urinary flow rate and prostate volume.Results:Comparative simulation a-nalysis showed significant differences in the total urethral pressure and flow rate between the normal and enlarged BNA models(P＜0.05).The maximum prostate displacement was found at the bladder neck,with moderate displacement and unchanged urethral diame-ter in the normal BNA model,but significant displacement and a reduced urethral opening diameter in the enlarged BNA model.FSI analysis confirmed an evident impact of enlarged BNA on urination,more significant in the AUR than in the non-AUR patients(P＜0.05).The BNAs in the patients with the maximum urinary flow rate(Qmax)of＜10,10-15 or＞15 ml/s were 83.7°±2.5°,67.5°±1.8° and 65.1°±4.8° respectively,with statistically significant difference between the former one and the latter two groups(P＜0.05).The BNAs in the patients with normal prostate volume or BPH of grade Ⅰ,Ⅱ,Ⅲ or Ⅳ were 65.0°±3.7°,67.2°±3.1°,71.5°±2.0°,82.8°±3.5° and 105.8°±6.0°,respectively(P＜0.05),with statistically significant difference between BPH grades Ⅲ and Ⅳ(P＜0.05)as well as between these two and the other three groups(P＜0.05),but not among the normal prostate volume,BPH grade Ⅰ and BPH grade Ⅱ groups(P＞0.05).Spearman correlation analysis indicated that BNA was strongly correlated with total prostate volume(TPV),transition zone volume(TZV),intravesical prostatic protrusion(IPP),prostatic urethral angle(PUA),IPSS,and Qmax(P＜0.05).Conclusion:Changes in BNA affect urination and are closely associated with the se-verity of prostate hyperplasia.The BNA may be an important anatomical factor for assessing the severity of lower urinary tract symptoms in BPH patients.

Objective To explore the clinical manifestations,endoscopic findings,histopathological changes,treatment,and prognosis of eosinophilic gastrointestinal disease(EGID)in children,with the aim of enhancing awareness among pediatricians about this condition.Methods Data of 267 children with EGID were prospectively collected from January 2019 to July 2022 at Jiangxi Children's Hospital,Hunan Children's Hospital,and Henan Children's Hospital.The age of onset,symptoms,physical signs,laboratory examination results,endoscopic findings,histopathological changes,and treatment outcomes were observed.Results Among the 267 children with EGID,the majority had mild(164 cases,61.4% )or moderate(96 cases,35.6% )clinical severity.The disease occurred at any age,with a higher prevalence observed in school-age children(178 cases).The main symptoms in infants were vomiting and hematemesis,while in toddlers,vomiting and bloody stools were prominent.Abdominal pain and vomiting were the primary symptoms in preschool and school-age children.Nearly half(49.4% )of the affected children showed elevated platelet counts on hematological examination,but there was no significant difference in platelet counts among children with mild,moderate,and severe EGID(P>0.05).Endoscopic findings in EGID children did not reveal significant specificity,and histopathological examination showed no specific structural damage.Among them,85.0% (227 cases)received acid suppression therapy,34.5% (92 cases)practiced dietary avoidance,20.9% (56 cases)received anti-allergic medication,and a small proportion(24 cases,9.0% )were treated with prednisone.Clinical symptoms were relieved in all patients after treatment,but three cases with peptic ulcers experienced recurrence after drug discontinuation.Conclusions Mild and moderate EGID are more common in children,with no specific endoscopic findings.Dietary avoidance,acid suppression therapy,and anti-allergic medication are the main treatment methods.The prognosis of EGID is generally favorable in children.[Chinese Journal of Contemporary Pediatrics,2024,26(2):139-144]

Objective To explore the changes in gut microbiota and levels of short-chain fatty acids(SCFA)in infants with cow's milk protein allergy(CMPA),and to clarify their role in CMPA.Methods A total of 25 infants diagnosed with CMPA at Children's Hospital Affiliated to Zhengzhou University from August 2019 to August 2020 were enrolled as the CMPA group,and 25 healthy infants were selected as the control group.Fecal samples(200 mg)were collected from both groups and subjected to 16S rDNA high-throughput sequencing technology and liquid chromatography-mass spectrometry to analyze the changes in gut microbial composition and metabolites.Microbial diversity was analyzed in conjunction with metabolites.Results Compared to the control group,the CMPA group showed altered gut microbial structure and significantly increased α-diversity(P＜0.001).The abundance of Firmicutes,Clostridiales and Bacteroidetes was significantly decreased,while the abundance of Sphingomonadaceae,Clostridiaceae_l and Mycoplasmataceae was significantly increased in the CMPA group compared to the control group(P＜0.001).Metabolomic analysis revealed reduced levels of acetic acid,butyric acid,and isovaleric acid in the CMPA group compared to the control group,and the levels of the metabolites were positively correlated with the abundance of SCFA-producing bacteria such as Faecalibacterium and Roseburia(P＜0.05).Conclusions CMPA infants have alterations in gut microbial structure,increased microbial diversity,and decreased levels of SCFA,which may contribute to increased intestinal inflammation.[Chinese Journal of Contemporary Pediatrics,2024,26(3):236-243]

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective:To construct and validate a risk prediction model for major complications 30 days after surgery in the elderly patients with hip fracture.Methods:A retrospective study was conducted to analyze the clinical data of 276 elderly patients with hip fracture who had been admitted to Department of Trauma and Orthopaedics, The Hospital Affiliated to Chengde Medical University from June 2019 to December 2021. There were 96 males and 180 females with an age of (74.5±9.3) years, and 139 femoral neck fractures and 137 intertrochanteric fractures. The outcome of this study was whether major complications occurred within 30 days after surgery. Multiple logistic regression analysis identified the risk factors for major complications in the elderly patients with hip fracture within 30 days after surgery. The forward step-by-step method and likelihood ratio test were used to screen the best prediction model. A nomogram was constructed to display the model. The stability and effectiveness of the model were evaluated by the receiver operating characteristic curve (ROC), Hosmer-Lemeshow goodness-of-fit test, clinical decision curve and clinical impact curve analysis.Results:Logistic regression analysis showed that decreased preoperative hemoglobin ( P< 0.05), time from admission to surgery >72 hours ( OR=3.001, 95% CI: 1.564 to 5.758, P<0.001), control of nutritional status (CONUT) score >4 points ( OR=3.394, 95% CI: 1.724 to 6.680, P<0.001), and age-adjusted modified frailty index (aamFI) >2 points ( OR=2.875, 95% CI: 1.548 to 5.339, P= 0.001), increased operation time ( OR=1.016, 95% CI: 1.006 to 1.025, P=0.001), and surgical bleeding >60 mL ( OR=2.373, 95% CI: 1.016 to 5.540, P=0.046) were independent risk factors for major complications within 30 days after surgery in the elderly patients with hip fracture. The area under the ROC curve in the logistic risk prediction model was 0.846 (95% CI: 0.799 to 0.889), and the results of Hosmer-Lemeshow goodness-of-fit test showed ( χ2=8.080, P=0.426). The clinical decision curve and clinical impact curve showed that the prediction model was accurate and effective. Conclusion:Based on the patients' preoperative hemoglobin, time from admission to surgery, control of nutritional status score, age-adjusted modified frailty index, operation time and surgical blood loss, this study has constructed successfully a risk prediction model for complications 30 days after surgery in the elderly patients with hip fracture which enables medical staff to predict the occurrence of major postoperative complications.
