ObjectiveTo observe the therapeutic effect of Chaishao Longmu decoction on insomnia in the patients with the syndrome of live depression and spleen deficiency and explore the correlation between infrared thermal imaging and insomnia with liver depression and spleen deficiency. MethodA total of 72 insomnia patients treated in the outpatient department of Shenzhen Hospital of Guangzhou University of Chinese Medicine （Futian） from May to December in 2022 were selected and randomized into a treatment group and a control group， with 36 patients in each group. The patients in the treatment group were treated with Chaishao Longmu decoction and those in the control group with eszopiclone for 4 weeks. The clinical efficacy， Pittsburgh sleep quality index （PSQI） score， TCM syndrome score and infrared thermal imaging characteristics ［temperature and temperature changes of frontal sleep line， frontal region， anterior trunk， Zhongwan （CV12）， conception vessel （CV）， left hypochondrium， right hypochondrium， dorsal trunk， and governor vessel （GV）］ of two groups were determined before and after treatment. ResultAfter treatment， the clinical response rate in treatment group was 91.67% （33/36）， which was higher than that （66.67%， 24/36） in the control group （Z=-2.617， P<0.01）. The treatment in both groups decreased the PSQI score and TCM syndrome score （P<0.01）， and the decreases were more significant in treatment group than in the control group （P<0.01）. After treatment， the total response rate of sleep line improvement in the treatment group was 86.11% （31/36）， which was higher than that （66.67%， 24/36） in the control group （Z=-2.591， P<0.05）. The frontal temperature of the two groups decreased （P<0.01） after treatment. Compared with those before treatment， the temperatures of anterior trunk， CV12， CV， left hypochondrium， right hypochondrium， dorsal trunk， and GV rose after treatment （P<0.01）. After treatment， the treatment group had lower frontal temperature and higher temperatures of anterior trunk， CV12， CV， left hypochondrium， right hypochondrium， dorsal trunk， and GV than the control group （P<0.01）. The treatment in the treatment group reduced the ∆T values of GV （P<0.01） and increased that of the CV12， CV， left hypochondrium， and right hypochondrium （P<0.05，P<0.01）. The treatment in the control group increased the ∆T value of CV12 （P<0.01）. After treatment， the treatment group had lower ∆T values of GV （P<0.01） and higher ∆T value of CV12， CV， left hypochondrium， and right hypochondrium （P<0.05， P<0.01） than the control group. Compared with that before treatment， the temperature difference between GV and CV in the two groups increased after treatment （P<0.01）. According to the infrared thermal image characteristics， the normal temperature difference between GV and CV was within the range of 0.5-1. The median value after treatment in the treatment group was 0.69 （0.52， 0.88）， which was within the normal range， indicating that the treatment group outperformed the control group. ConclusionChaishao Longmu decoction can alleviate short-term insomnia by soothing liver， invigorating spleen， harmonizing the middle energizer， and regulating GV and CV. With definite clinical effect， this decoction deserves promotion. Furthermore， the frontal temperature， sleep line， CV12， CV ∆T， and temperature difference between GV and CV revealed by the infrared thermal images could be used for the diagnosis and of insomnia with liver depression and spleen deficiency.

GAO Wei-bin's clinical experience in treatment of neurogenic bladder with acupuncture / 中国针灸

The paper introduces GAO Wei-bin's clinical experience in acupuncture treatment for neurogenic bladder. In association with the etiology, the location and types of neurogenic bladder and in accordance with nerve anatomy and meridian differentiation, the acupoints are selected accurately in treatment. Four acupoint prescriptions are allocated. For frequent urination and urinary incontinence, the foot-motor-sensory area of scalp acupuncture, Shenshu (BL 23) and Huiyang (BL 35) are used. For all kinds of urine retention, especially the patients who are not suitable for acupuncture at the lumbar region, Zhongji (CV 3), Qugu (CV 2), Henggu (KI 11) and Dahe (KI 12) are selected. For all kinds of urine retention, Zhongliao (BL 33) and Ciliao (BL 32) are applicable. For the patients with both dysuria and urinary incontinence, Zhongliao (BL 33), Ciliao (BL 32) and Huiyang (BL 35) are chosen. In treatment of neurogenic bladder, both biao (root causes) and ben (primary symptoms) are considered, as well as the accompanying symptoms; and electroacupuncture is combined accordingly. During the delivery of acupuncture, the sites where the acupoints located are detected and palpated so as to rationally control the depth of needle insertion and the operation of reinforcing and reducing needling techniques.

Professor GAO Wei-bin's clinical experience of using electroacupuncture for dry eye / 中国针灸

The academic thoughts of professor GAO Wei-bin regarding the use of electroacupuncture in the treatment of dry eye are introduced. Professor GAO believes that the occurrence of dry eye is mainly related to the stagnation of qi and blood in the eye meridians, leading to inadequate nourishment of the eyes. The acupuncture treatment principle focuses on promoting blood circulation, clearing and benefiting the eye orifices. By integrating traditional acupuncture theory with modern neuroanatomy, the treatment approach centers on stimulating the lacrimal gland, emphasizing the importance of promoting, addressing symptoms as a priority, and considering both the root cause and symptoms.The precise acupoint selection is emphasized. Acupoints of periocular region, such as Taiyang (EX-HN 5) and Leixian point are selected along with Fengchi (GB 20) and Gongxue point to treat dry eye. Attention is also given to the use of electroacupuncture and the selection of its frequencies, emphasizing specific needling techniques based on the severity and classification of the disease.

Cardiomyocyte Energy Metabolism in Mammalian Cardiac Regeneration / 中山大学学报(医学科学版)

Cardiovascular disease， such as coronary heart disease and acute myocardial infarction， is a leading cause of death globally. Due to the limited proliferative and regenerative capacity of adult mammalian cardiomyocytes （CMs）， any of the current therapies cannot reverse the massive loss of CMs and subsequent fibrosis resulting from cardiac injury. Mammals mainly rely on glycolysis in the embryonic stage and fatty acid oxidation after birth for energy production. Recent reports have indicated that this metabolic pattern switch is closely related to the loss of CM proliferation. In this review， we summarize the biological characteristics of CMs and advances in heart regeneration， meanwhile shed light on the important role of CMs energy metabolism in cardiac regeneration.

OBJECTIVE@#With the help of finite element analysis, to explore the effect of proximal humeral bone cement enhanced screw plate fixation on the stability of internal fixation of osteoporotic proximal humeral fracture.@*METHODS@#The digital model of unstable proximal humeral fracture with metaphyseal bone defect was made, and the finite element models of proximal humeral fracture bone cement enhanced screw plate fixation and common screw plate fixation were established respectively. The stress of cancellous bone around the screw, the overall stiffness, the maximum stress of the plate and the maximum stress of the screw were analyzed.@*RESULTS@#The maximum stresses of cancellous bone around 6 screws at the head of proximal humeral with bone cement enhanced screw plate fixation were 1.07 MPa for No.1 nail, 0.43 MPa for No.2 nail, 1.16 MPa for No.3 nail, 0.34 MPa for No.4 nail, 1.99 MPa for No.5 nail and 1.57 MPa for No.6 nail. These with common screw plate fixation were:2.68 MPa for No.1 nail, 0.67 MPa for No.2 nail, 4.37 MPa for No.3 nail, 0.75 MPa for No.4 nail, 3.30 MPa for No.5 nail and 2.47 MPa for No.6 nail. Overall stiffness of the two models is 448 N/mm for bone cement structure and 434 N/mm for common structure. The maximum stress of plate appears in the joint hole:701MPa for bone cement structure and 42 0MPa for common structure. The maximum stress of screws appeared at the tail end of No.4 nail:284 MPa for bone cement structure and 240.8 MPa for common structure.@*CONCLUSION@#Through finite element analysis, it is proved that the proximal humerus bone cement enhanced screw plate fixation of osteoporotic proximal humeral fracture can effectively reduce the stress of cancellous bone around the screw and enhance the initial stability after fracture operation, thus preventing from penetrating out and humeral head collapsing.

Diagnostic value of contrast-enhanced ultrasound in hepatic epithelioid hemangioendothelioma / 中华肝脏病杂志

Objective: To investigate the features of contrast-enhanced ultrasound (CEUS) in hepatic epithelioid hemangioendothelioma (HEHE) in order to improve the preoperative diagnosis rate. Methods: CEUS images of 32 pathologically-proven cases of hepatic epithelioid hemangioendothelioma from January 2004 to August 2021 were collected. Lesions were analyzed to observe the features of enhancement mode, enhancement intensity, and distinct enhancement phases. Results: Among the 32 cases, one had a solitary lesion, 29 had multiple lesions, and two had diffuse-type lesions. Contrast-enhanced ultrasound revealed a total of 42 lesions in 32 cases. In terms of arterial phase enhancement, 18 lesions had overall enhancement, six lesions had uneven dendritic enhancement, 16 lesions had rim-like enhancement, and two lesions had just slight peripheral spot enhancement around the lesions. Among the three cases, there were multiple lesions that had overall enhancement and ring enhancement. In terms of the enhancement phase, 20 lesions showed "fast progression", 20 lesions showed "same progression", and two lesions showed "slow progression". During the late arterial or early portal venous phases with rapid washout, all lesions manifested as hypoechoic. With peaked enhanced intensity, 11 lesions had a lower enhancement intensity than the surrounding normal liver parenchyma; 11 lesions had the same enhancement degree as the surrounding normal liver parenchyma; and 20 lesions had a higher enhancement degree than the surrounding normal liver parenchyma. All 16 ring-enhancing lesions had marked hyperenhancement. In the typical enhancing lesions, four showed hyperenhancement, five showed low enhancement, and nine showed isoenhancement. In the dendrite-enhancing lesions, there were two isoenhancing and four hypoenhancing. Contrast-enhanced ultrasound delineated the boundaries of all lesions more clearly than two-dimensional ultrasound. Conclusion: Contrast-enhanced ultrasound has certain value in the diagnosis of hepatic epithelioid hemangioendothelioma.

Overexpression of long noncoding RNA PTPRG-AS1 is associated with poor prognosis in epithelial ovarian cancer

SUMMARY OBJECTIVE Long noncoding RNAs (lncRNAs) have been shown to play a critical role in tumor progression. Abnormal expression of LncRNA PTPRG antisense RNA 1 (PTPRG-AS1) has been reported in several tumors. Hence, we aimed to determine the expression and clinical significance of PTPRG-AS1 in epithelial ovarian cancer (EOC) patients. METHODS The expressions of PTPRG-AS1 were assessed in 184 pairs of EOC tumor specimens and adjacent normal tissues. The levels of target lncRNAs and GAPDH were examined using standard SYBR-Green methods. The relationships between the expressions of PTPRG-AS1 and the clinicopathological features were analyzed using the chi-square test. Multivariate analysis using the Cox proportional hazards model was performed to assess the prognostic value of PTPRG-AS1 in EOC patients. RESULTS We confirmed that the expressions of PTPRG-AS1 were distinctly higher in the EOC tissue compared with the adjacent non-tumor specimens (p < 0.01). Higher levels of PTPRG-AS1 in EOC patients were associated with advanced FIGO stage (p = 0.005), grade (p = 0.006), and distant metastasis (p = 0.005). Survival analyses revealed that patients with high expressions of PTPRG-AS1 had a distinctly decreased overall survival (p = 0.0029) and disease-free survival (p = 0.0009) compared with those with low expressions of PTPRG-AS1. Multivariate assays indicated that PTPRG-AS1 expression was an independent prognostic factor for both overall survival and disease-free survival in EOC (Both p < 0.05). CONCLUSIONS Our study suggests that PTPRG-AS1 may serve as a novel prognostic biomarker for EOC patients.

RESUMO OBJETIVO Sabe-se que RNAs longos não codificantes (lncRNAs) desempenham um papel crítico na progressão tumoral. A expressão anormal do RNA 1 anti-senso LncRNA PTPRG (PTPRG-AS1) já foi relatada em diversos tumores. Assim, buscamos determinar a expressão e significância clínica do PTPRG-AS1 em pacientes com câncer de ovário epitelial (COE). METODOLOGIA As expressões do PTPRG-AS1 foram avaliadas em 184 pares de amostras tumorais de COE e tecidos normais adjacentes. Os níveis de lncRNAs e GAPDH alvo foram examinados usando o método padrão de SYBR Green. As relações entre as expressões do PTPRG-AS1 e as características clínico-patológicas foram analisadas através do teste qui-quadrado. Uma análise multivariada utilizando o modelo de riscos proporcionais de Cox foi realizada para avaliar o valor prognóstico do PTPRG-AS1 em pacientes com COE. RESULTADOS Constatou-se que as expressões do PTPRG-AS1 foram nitidamente maiores nos tecidos de COE em relação aos espécimes adjacentes não tumorosos (p<0,01). Níveis mais elevados do PTPRG-AS1 em pacientes com COE foram associados a um estágio avançado de FIGO (p = 0,005), grau (p = 0,006) e metástases à distância (p = 0,005). As análises de sobrevida revelaram que pacientes com expressões elevadas do PTPRG-AS1 tiveram uma diminuição significativa da sobrevida global (p = 0,0029) e da sobrevida livre de doença (p = 0,0009) em relação àqueles com baixas expressões do PTPRG-AS1. As análises multivariadas indicaram que a expressão do PTPRG-AS1 foi um fator de prognóstico independente tanto para a sobrevida global quanto para a sobrevida livre de doença em pacientes com EOC (p < 0,05). CONCLUSÃO Nosso estudo sugere que o PTPRG-AS1 pode ser um novo biomarcador prognóstico para pacientes com COE.

Whole blood genomic DNA of AS was extracted to perform whole exome sequencing, the results were compared with human databases, common variations which had been reported were wiped out, then non synonymous single nucleotide variants(SNVs) from the family members were combined, and candidate genes was selected initially.@*RESULTS@#Totally 80 G data was obtained from AS family with high quality.By comparing results between patient and normal subject, and filtering with number of biological database, the result showed heterozygous mutation of JAK2 gene 12 exon c.1709 A>G (p.Tyr570Cys) may be the potential disease-causing gene. The variant c.1151T>C of MUC3A gene may be one of the causes of intestinal symptoms in the family members.@*CONCLUSION@#It is feasible to find t candidate gene mutations of AS by Exon sequencing. The mutation c.1709 A>G in gene JAK2 identified by whole exome sequencing might be the pathogenic mutation in this AS pedigree.

Therapeutic observation of grain-sized moxibustion for chemotherapy-induced myelosuppression for non-small cell lungcancer / 针灸推拿医学（英文版）

Objective: To observe the clinical efficacy of grain-sized moxibustion in treating chemotherapy-induced myelosuppression for non-small cell lung cancer (NSCLC) and its effect on quality of life (QOL). Methods: Eighty NSCLC patients admitted to the Inpatient Department of Zhejiang Cancer Hospital between September 2016 and March 2018 were recruited and divided into an observation group and a control group by random number method, with 40 cases in each group. The two groups both received chemotherapy with paclitaxel plus cisplatin (TP regimen). The control group received oral administration of leucogen tablets starting from the first day of chemotherapy, 20 mg each time, three times a day, for consecutive 14 d; the observation group was additionally given grain-sized moxibustion, once a day, five days per week at a two-day interval, until the fourteenth day. The myelosuppression severity was observed and compared between the two groups prior to chemotherapy, at the 3rd, 7th and 14th days of chemotherapy; the QOL in the two groups was evaluated before chemotherapy, at the 14th and 21st days of chemotherapy. Results: Regarding myelosuppression, the peripheral blood indicators increased significantly at the 3rd day of chemotherapy in both groups (P<0.05 or P<0.01); at the 7th and 14th days of chemotherapy, the peripheral blood indicators presented a decreasing tendency in the two groups, but the level in the observation group was still significantly higher than that before chemotherapy (P<0.01); at the 3rd, 7th and 14th days of chemotherapy, the peripheral blood indicators in the observation group were higher than those in the control group (P<0.05 or P<0.01); the occurrence rate of myelosuppression in the observation group was significantly lower than that in the control group (P<0.01). The QOL score in the observation group was markedly higher than that in the control group at the 14th and 21st days of chemotherapy (both P<0.05). Conclusion: Grain-sized moxibustion can effectively improve myelosuppression after chemotherapy for NSCLC, reducing its occurrence and enhancing the patient's QOL.

Impact of childhood sexual abuse on risky sexual behaviors among men who have sex with men in Guangzhou / 中华疾病控制杂志

Objective To explore the experience of childhood sexual abuse (CSA) among men who have sex with men (MSM) in Guangzhou, and to evaluate its impact on risky sexual behaviors in adulthood. Methods A non-probability sampling method was used to recruit MSM aged 18 years and over in Guangzhou. Sociodemographic characteristics, experience of CSA and risky sexual behaviors during the past 6 months were collected using an electronic questionnaire. 2 tests were used to compare the prevalence of CSA and risky sexual behaviors during the past 6 months among different sociodemographic characteristics. Logistic regressions were performed to assess the impact of CSA on risky sexual behaviors. Results Overall, 976 MSM were included with an average age of (28.35±6.83) years old. Nearly one-third (26.95%, 263/976) of MSM experienced CSA. Participants having multiple sexual partners (MSP) and unprotected anal intercourse (UAI) during the past 6 months accounted for 61.68% (602/976) and 47.95% (468/976), respectively. After adjusting age, ethnicity, household registration, local residence time, marital status, education, employment status, monthly income and sexual orientation, the results of multivariate Logistic regression showed that MSM who experienced CSA were likely to have MSP during the past 6 months (aOR=1.62; 95%CI: 1.19-2.22) than those did not experience CSA. But the association between UAI and CSA was not statistically significant. Conclusions The prevalence of CSA among MSM in Guangzhou is high. CSA can substantially increase the risk of risky sexual behaviors in adulthood. Intervention to reduce the risk of sexual risk behaviors may need to be tailored for MSM who experienced CSA.
