ObjectiveTo evaluate the clinical efficacy and safety of Huaban Jiedu Formulation （化斑解毒方， HJF） in treating psoriasis vulgaris with blood-heat syndrome. MethodsA randomized， double-blind， placebo-controlled study was conducted with 60 patients diagnosed with psoriasis vulgaris of blood-heat syndrome. Patients were randomly assigned to either a treatment group or a control group， with 30 cases in each. The treatment group received HJF granules orally， one dose a day， combined with topical Qingshi Zhiyang Ointment （青石止痒软膏）， while the control group received placebo granules， one dose a day， combined with the same topical ointment. Both groups were topically treated twice daily of 28 days treatment cours. Psoriasis area and severity index （PASI）， visual analogue scale for pruritus （VAS）， traditional Chinese medicine （TCM） syndrome scores， dermatology life quality index （DLQI）， and psoriasis life stress inventory （PLSI） were assessed before treatment and on day 14 and day 28. Response rates for PASI 50 （≥50% reduction） and PASI 75 （≥75% reduction）， as well as overall clinical efficacy， were compared between groups. Serum levels of interleukin-6 （IL-6） and interleukin-17 （IL-17） were measured before and after 28 days of treatment. Adverse reactions during treatment were recorded. ResultsAfter 28 days of treatment， both groups showed significant reductions in PASI total score， lesion area score， erythema， scaling， and infiltration scores， pruritus VAS score， TCM syndrome score， DLQI， PLSI， and serum IL-6 and IL-17 levels （P＜0.05）. Compared to the control group， the treatment group had significantly greater improvements in PASI total score and erythema score， TCM syndrome score， serum IL-6 and IL-17 levels， and PASI 50 response rate after 28 days （P＜0.05）. Between-group comparisons of score differences before and after 28-day treatment revealed that the treatment group showed significantly better improvements in PASI total， lesion area score， erythema score， TCM syndrome score， DLQI， PLSI， and inflammatory markers （P＜0.05 or P＜0.01）. The total effective rate on day 14 and day 28 was 40.00% （12/30） and 83.33% （25/30） in the treatment group， versus 6.90% （2/29） and 41.38% （12/29） in the control group， respectively. The clinical efficacy in the treatment group was significantly superior to that in the control group （P＜0.05）. Mild gastric discomfort occurred in 3 patients in the treatment group and 1 in the control group. ConclusionHJF can effectively improve skin lesions and TCM symptoms relieve pruritus， enhance quality of life， and reduce inflammatory markers IL-6 and IL-17， in patients with blood-heat syndrome of psoriasis vulgaris， with a good safety profile.

Cochlear nerve deficiency（CND） is a rare inner ear malformation characterized by a hypoplastic or absent cochlear nerve, resulting in variable hearing loss or total deafness, depending on the quantity of nerve fibers present. About 18% of congenital hearing loss are associated with CND. It is a disease of uncertain cause. The outcome of auditory implant in CND patients varies widely. This article will discuss the related issues of CND.

Objective To compare the efficacy of electroacupuncture in traditional Chinese medicine with the opioid adjuvant drug dezocine.Methods 122 patients undergoing elective laparoscopic cholecystectomy at the Second Affiliated Hospital of Kunming Medical University between October 12,2023,and April 05,2024,were randomly allocated into three groups:dezocine group(D group,n=40),electroacupuncture group(E group,n=42),and electroacupuncture combined with dezocine group(ED group,n=40).Patients received 10 mg dezocine,electroacupuncture,or electroacupuncture+10 mg dezocine after cholecystectomy.Pain threshold index(PTi),pain index(Pi),and visual analogue scale(VAS)scores were observed at different time points during surgery.Vital signs were recorded,and adverse reactions within 24 hours postoperatively were noted.Results There were no statistically significant differences in PTi among groups before electroacupuncture(T1)(P>0.05).At the end of electroacupuncture(T2)and after cholecystectomy(T3),the PTi values in the E and ED groups were lower than the D group(P<0.05).At the end of surgery(T4)and upon extubation(T5),the PTi values of all three groups reached a tolerable level for patients,with the E and D groups showing higher PTi values compared to the ED group(P<0.05).There were no statistically significant differences in postoperative pain scores(Pi)and VAS at various time points(P>0.05).Conclusion Electroacupuncture demonstrates analgesic efficacy non-inferior to opioid drugs and can be recommended as a postoperative pain management technique for laparoscopic cholecystectomy patients.

Objective: To investigate the iodine nutrition status of children aged 8-10 in Guangming, Longhua and Yantian District of Shenzhen in 2023, and to explore the influencing factors of thyroid volume. To evaluate prevention strategies and to provide a scientific basis for the elimination of iodine deficiency disorders. Methods: Urine and household salt samples were randomly collected from 580 non-boarding students aged 8-10 years foriodine content detection. Thyroid volume was measured using a fully digital ultrasound imaging system, and goiter prevalence was calculated. Results: A total of 580 samples was tested. The median salt iodine concentration was 23.86 mg/kg, with 93.62% qualified iodized salt and 94.48% coverage rate. The median of urinary iodine was 265.00 μg/L, mainly distributed between 200 - < 300 μg/L and ≥300 μg/L. The proportion of children with ap⁃ propriate iodine was 20. 86% , and the proportion of children with insufficient or excessive urinary iodine levels was 10. 86% and 68. 28% of the total surveyed population , respectively. The median thyroid volume was 3. 27 mL , and the goiter rate was 1. 72% . Multiple linear regression analysis showed that age was the risk factor for thyroid volume (8=0 328, P<0.05). while urinary iodine was the protective factor for thyroid volume(B=-4.134x10-4,P<0.05). Conclusion The qualified iodized salt rate, median of urinary iodine,and goiter prevalence of 580 children aged 8 - 10 meet the elimination criteria for iodine deficiency disorders. Age and urinary iodine are closely related to thyroid volume change. The urinary iodine level of children is generally high and requires serious attention.

Objective To investigate the efficacy and safety of using the fourth arm in retroperitoneal robot-assisted partial nephrectomy(PN)for cT1b stage renal tumors.Methods Clinical data of 49 patients with cT1b stage renal tumors who underwent retroperitoneal robot-assisted PN performed by the same surgeon in our hospital during Jan.2022 and Dec.2023 were retrospectively analyzed.The patients were divided into two groups based on whether the fourth arm was used or not:application group(n=21)and non-application group(n=28).The basic information,operation time,warm ischemia time,intraoperative blood loss,postoperative complications and other data were compared between the two groups.Results All operations were successful,with no conversion to open surgery or radical nephrectomy.The application group had significantly shorter operation time[(128.76±31.58)min vs.(151.11±33.21)min,P=0.021],shorter warm ischemia time[(24.67±4.80)min vs.(27.61±3.54)min,P=0.017],and less intraoperative blood loss[(109.05±39.99)mL vs.(139.29±54.43)mL,P=0.037]compared with the non-application group.The increase of postoperative creatinine was(18.64±16.05)μmol/L in the application group and(20.30±13.49)μmol/L in the non-application group respectively.Complications occurred in 3 cases in the application group and 5 cases in the non-application group,with no significant difference(P＞0.05).Conclusion When we perform the retroperitoneal robot-assisted partial nephrectomy for cT1b stage renal tumors,using the fourth arm can shorten the operation time and warm ischemia time,and reduce the intraoperative blood loss,which should be applied more in clinic.

Objective To investigate the correlation between the expression of long non-coding ribonucleic acid growth arrest specific 5(lncRNA GAS5),phospholysine phosphohistidine inorganic pyrophosphate phos-phatase(LHPP)and epithelial-mesenchymal transition(EMT)in cancer tissues of patients with non-small cell lung cancer(NSCLC)and its clinical significance.Methods Cancer tissues and adjacent tissues of 90 patients with NSCLC who underwent surgical resection in the First Hospital Affiliated to Hebei North College from June 2018 to January 2020 were collected.The expressions of lncRNA GAS5,LHPP and EMT-associated pro-teins[E-calmodulin(E-Cad),N-calmodulin(N-Cad),and vimentin(VIM)]were detected by real-time fluores-cence quantitative polymerase chain reaction.The relationship between lncRNA GAS5 and LHPP mRNA and clinicopathological features in cancer tissues of NSCLC patients was analyzed,and the correlation between ln-cRNA GAS5 and LHPP mRNA and EMT-associated proteins expression in cancer tissues of NSCLC patients was analyzed by Pearson correlation.Kaplan-Meier method was used to plot the survival curves of NSCLC pa-tients with different lncRNA GAS5 and LHPP mRNA expressions,and multivariate Cox regression was used to analyze the prognostic factors of NSCLC patients.Results The expressions of lncRNA GAS5,LHPP mR-NA and E-Cad mRNA in cancer tissues of NSCLC patients were lower than those in adjacent tissues,while the expressions of N-Cad mRNA and VIM mRNA were higher than those in adjacent tissues,with statistical sig-nificance(P＜0.05).Pearson correlation analysis showed that lncRNA GAS5 in cancer tissues of NSCLC pa-tients was positively correlated with E-Cad mRNA expression(r=0.724,P＜0.001),and negatively correla-ted with N-Cad mRNA and VIM mRNA expression(r=-0.699,-0.689).P＜0.001);lncRNA GAS5 was positively correlated with LHPP mRNA expression(r=0.651,P＜0.001).The mRNA expressions of ln-cRNA GAS5 and LHPP in cancer tissues of NSCLC patients with different degrees of differentiation,tumor TNM stage and lymph node metastasis were significantly different(P＜0.05).Kaplan-Meier survival curve a-nalysis showed that the 3-year overall survival rate in the lncRNA GAS5 high expression group[68.18％(30/44)]was higher than that in the lncRNA GAS5 low expression group[36.96％(17/46)].The 3-year overall survival rate in the high LHPP mRNA expression group[67.39％(31/46)]was higher than that in the lowLHPP mRNA expression group[36.36％(16/44)],and the difference was statistically significant(x2=10.274,10.322,P＜0.05).Low differentiation,TNM stage Ⅲ and lymph node metastasis were independent risk factors for death in NSCLC patients,and lncRNA GAS5≥1.32 and LHPP mRNA≥1.12 were independ-ent protective factors(P＜0.05).Conclusion The low expression of lncRNA GAS5 and LHPP mRNA in cancer tissues of patients with NSCLC is related to EMT-associated proteins expression,differentiation de-gree,tumor TNM stage,lymph node metastasis and prognosis,and may become a new target for the diagnosis and treatment of NSCLC.

Objective To observe the effects and mechanism of Guiqi Yiyuan Ointment on immune function in 12C6+ beam bystander-effect rats.Methods Totally 60 Wistar rats were randomly divided into blank group,model group,positive control group,and TCM low-,medium-,and high-dosage groups,with 10 rats in each group.TCM low-,medium-,and high-dosage groups were given 1.2,2.4,and 4.8 g/kg Guiqi Yiyuan Ointment for gavage,and the blank group,model group and positive control group were given equal dose of sodium chloride solution for gavage for 14 days.Positive control group received intraperitoneal injection of amifostine 30 minutes before modeling.On the 15th day,except the blank group,the other groups were given 4 Gy 12C6+ beam of single irradiation on the right lung.After irradiation,each group was given gavage for 3 days.The general condition of rats was observed,peripheral blood leukocyte(WBC),red blood cell(RBC),hemoglobin(Hb),platelet(PLT)levels were detected,ELISA was used to detect the contents of serum interleukin(IL)-4 and interferon-γ(IFN-γ),lung and spleen organ indices were calculated,HE staining was used to observe the pathological morphology of left lung and spleen tissues,and flow cytometry was used to detect the proportion of CD4+ and CD8+ T lymphocytes in the spleen,qPCR was used to detect the expressions of T-bet and GATA-3 mRNA in right lung and spleen tissues.Results Compared with the blank group,the model group rats showed a decrease in peripheral blood WBC,an increase in RBC,Hb,PLT,and an decrease in serum IL-4 and IFN-γ contents;the organ indices of left lung and spleen was significantly reduced,the alveoli were deformed,the alveolar walls became thicker,the alveolar cavities shrank,the lung tissue was significantly bleeding,the spleen tissue structure was severely damaged,the splenic sinus cavity became narrower,and the splenic cord showed fibrous hyperplasia;the proportion of CD4+ T lymphocytes and CD4+/CD8+ ratio in spleen tissue of the model group decreased,while the proportion of CD8+ T lymphocytes increased,the expression of T-bet mRNA in the left lung and spleen tissues decreased,while the expression of GATA-3 mRNA increased,with statistical significance(P<0.05).Compared with the model group,the positive control group and TCM medium-and high-dosage groups showed an increase in peripheral blood WBC,an decrease in RBC,Hb,PLT,an increase in serum IL-4 and IFN-γ contents;the index of left lung and spleen organs increased in TCM high-dosage group;the pathological damage of left lung and spleen tissues in each treatment group alleviated to varying degrees,while the proportion of CD4+ T lymphocytes and CD4+/CD8+ ratio in spleen tissue of the positive control group and TCM high-dosage group increased,the proportion of CD8+ T lymphocytes decreased,the expression of T-bet mRNA in left lung and spleen tissues increased,and the expression of GATA-3 mRNA decreased,with statistical significance(P<0.05).Conclusion Guiqi Yiyuan Ointment can alleviate the lung and spleen injury of rats induced by 12C6+ beam radiation.Its mechanism is related to regulating the proportion of CD4+,CD8+ T lymphocytes and the expression of T-bet and GATA-3,and recovering cellular immune function.

Objective:To summarize the clinical, pathological and molecular characteristics of various types of pediatric glioma, and to explore the differences in the morphology and clinical significance among various types of pediatric glioma.Methods:Based on the fifth edition of the World Health Organization classification of central nervous system tumors, this study classified or reclassified 111 pediatric gliomas that were diagnosed at Guangzhou Medical University Affiliated Women and Children′s Medical Center from January 2020 to June 2023. The clinical manifestations, imaging findings, histopathology, and molecular characteristics of these tumors were analyzed. Relevant literature was also reviewed.Results:The 111 patients with pediatric glioma included 56 males and 55 females, with the age ranging from 10 days to 13 years (average age, 5.5 years). Clinically, manifestations presented from 5 days to 8 years before the diagnosis, including epilepsy in 16 cases, increased intracranial pressure in 48 cases and neurological impairment in 66 cases. MRI examinations revealed tumor locations as supratentorial in 43 cases, infratentorial in 65 cases, and spinal cord in 3 cases. There were 73 cases presented with a solid mass and 38 cases with cystic-solid lesions. The largest tumor diameter ranged from 1.4 to 10.6 cm. Among the 111 pediatric gliomas, there were 6 cases of pediatric diffuse low-grade glioma (pDLGG), 63 cases of circumscribed astrocytoma glioma (CAG), and 42 cases of pediatric diffuse high-grade glioma (pDHGG). Patients with pDLGG and CAG were younger than those with pDHGG. The incidence of pDLGG and CAG was significantly lower in the midline of the infratentorial region compared to that of pDHGG. They were more likely to be completely resected surgically. The pDLGG and CAG group included 4 cases of pleomorphic xanthoastrocytoma, showing histological features of high-grade gliomas. Among the high-grade gliomas, 13 cases were diffuse midline gliomas and also showed histological features of low-grade glioma. Immunohistochemical studies of H3K27M, H3K27ME3, p53, ATRX, BRAF V600E, and Ki-67 showed significant differences between the pDLGG and CAG group versus the pDHGG group ( P<0.01). Molecular testing revealed that common molecular variations in the pDLGG and CAG group were KIAA1549-BRAF fusion and BRAF V600E mutation, while the pDHGG group frequently exhibited mutations in HIST1H3B and H3F3A genes, 1q amplification, and TP53 gene mutations. With integrated molecular testing, 2 pathological diagnoses were revised, and the pathological subtypes of 35.3% (12/34) of the pediatric gliomas that could not be reliably classified by histology were successfully classified. Conclusions:There are significant differences in clinical manifestations, pathological characteristics, molecular variations, and prognosis between the pDLGG, CAG and pDHGG groups. The integrated diagnosis combining histology and molecular features is of great importance for the accurate diagnosis and treatment of pediatric gliomas.
