Clinical Study of Modified Shenqi Pill （肾气丸） Plus Tongdu Tiaoshen Acupuncture （通督调神针刺） for Neurogenic Bladder After Spinal Cord Injury of Kidney-Yang Deficiency Syndrome / 中医杂志

ObjectiveTo observe the clinical efficacy of modified Shenqi Pill （肾气丸） plus Tongdu Tiaoshen Acupuncture （通督调神针刺） in the treatment of neurogenic bladder after spinal cord injury of kidney-yang deficiency syndrome. MethodsForty-six patients were randomly divided into 23 cases each in the control group and the treatment group. Both groups were given conventional treatment， i.e. oral methylcobalamin tablets （0.5 mg each time， 3 times a day） and paraplegic conventional acupuncture （once a day， 6 consecutive days a week）. The control group was given simple bladder function rehabilitation training on the basis of the conventional treatment； and the treatment group was given modified Shenqi Pill orally （1 dose a day， 150 ml each time， taken warmly in morning and evening） and Tongdu Tiaoshen Acupuncture （once a day， 6 consecutive days per week） in addition to what were given to the control group. The treatment course lasted for 4 weeks. The 24 h urination frequency， 24 h urine leakage frequency， 24 h single urine volume， bladder residual urine volume， international lower urinary tract symptom （LUTS） score， traditional Chinese medicine （TCM） syndrome score were compared between the two groups， and clinical effectiveness and TCM syndrome effectiveness were compared between the two groups after treatment. ResultsTwenty patients in each group were finally analyzed in this study. The number of 24 h urination， the number of 24 h urine leakage， bladder residual urine volume， LUTS score， and the TCM syndrome scores decreased after treatment in both groups， and the 24 h single urine volume increased （P＜0.01）； and much more improvement was found of each index in the treatment group than in the control group （P＜0.05 or P＜0.01）. The total clinical effectiveness and TCM syndrome effectiveness in the treatment group was 85.00% （17/20） respectively， which were statistically significantly higher than 45.00% （the total clinical effectiveness， 9/20） and 60.00% （TCM syndrome effectiveness， 12/20） in the control group （P＜0.01）. ConclusionModified Shenqi Pill plus Tongdu Tiaoshen Acupuncture can signi-ficantly improve the clinical symptoms of neurogenic bladder patients after spinal cord injury of kidney-yang deficiency syndrome， having better effectiveness than simple bladder function rehabilitation training， and its mechanism may be related to the improvement of the injured nerve function innervating the bladder.

Dynamic and static ultrasound features predictive of vesicoureteral reflux and renal damage in children and adolescents with neurogenic bladder

ABSTRACT Purpose: This study aimed to analyze the diagnostic accuracy of dynamic and static ultrasound (DSUS) in detecting vesicoureteral reflux (VUR) and renal scarring in a cohort of children with neurogenic bladder (NB). Materials and Methods: A retrospective, longitudinal, observational study was conducted using the Reporting Diagnostic Accuracy Studies guideline. The DSUS (index test) data were compared with voiding cystourethrography (VCUG) and renal scintigraphy 99mTc-dimercaptosuccinic (reference tests). Overall performance for predicting VUR and renal scarring was assessed using renal pelvic diameter (RPD)/distal ureteral diameter and renal parenchymal thinning on DSUS, respectively. Results: A total of 107 patients (66 girls, median age 9.6 years) participated. Seventeen patients (15.9%) presented VUR, eight bilateral. For overall reflux grade, the AUC was 0.624 for RPD and 0.630 for distal ureteral diameter. The diagnostic performance for detecting high-grade VUR was slightly better for DSUS parameters. The AUC was 0.666 for RPD and 0.691 for distal ureteral diameter. The cut-offs of 5 mm for RPD and 6.5 mm for distal ureteral diameter presented the best diagnostic odds ratio (DOR) to identify high-grade VUR. The increase of RPD during detrusor contractions showed an accuracy of 89.2%. The thinness of renal parenchyma presented an accuracy of 88% for renal scarring. Conclusion: DSUS predicts VUR and renal scarring in children with NB with fair to good accuracy, and all measurements exhibited a high negative predictive value (NPV). The increase in RPD during voiding or detrusor contractions proved to be the most accurate parameter for indicating the presence of VUR in this study.

A rare case of migrainous left bell抯 palsy after migrainous right external ophthalmoplegia - A case report

Migraine increased the risk of Bell palsy in the total population. Among migraine patients, between ?30 and <60 years old are at an increased risk of Bell palsy. A migraine is a primary headache characterized by recurrent headache attacks triggered by various factors. As much as 10% of the global population is thought to experience migraine headaches. It was earlier considered that migraine headaches were triggered by the dilation of cerebral vessels, and the recent evidence supports that migraine attacks can also occur in the absence of vasodilation. According to the researchers, the direct neural effects from the trigeminal nerve to the facial nerve could contribute to the risk of facial palsy among patients with migraine. An alteration of the trigeminovascular function has been suggested to trigger migraines. The neurogenic inflammation of the facial nerve trunk caused by its proximity to the dilated posterior auricular/ stylomastoid/ occipital and superficial temporal arteries during a migraine attack leads to a temporary lower motor neuron type of paresis of the muscles supplied by the facial nerve. We herewith report a rare case of migrainous left Bell抯 palsy after migrainous right external ophthalmoplegia, treated with Sumatriptan.

[Errata] Estudo piloto sobre diâmetro do canal lombar e distância percorrida em pacientes com estenose espinhal lombar: um modelo de predição multivariado / [Erratum] Pilot study on lumbar canal diameter and walking distance in patients with lumbar spinal stenosis: a multivariate prediction model

INTRODUCTION: Neurogenic claudication (NC) is the classic clinical presentation of patients with Lumbar Spinal Stenosis (LSS). These patients may or may not present with symptoms of leg pain and difficulty walking. These symptoms are exacerbated while walking and standing and are eased by sitting or bending forward. METHOD: Patients with LSS, having a lumbar canal diameter of ≤12mm, were recruited from a recognized Tertiary care hospital. Each subject's demographic characteristics and anthropometrics were noted, and the testing procedure was explained. The canal diameter was documented with the help of an MRI report. A self-paced walking test was used to assess the walking distance. STATISTICAL ANALYSIS: Depending on the normality of the data, the Pearson correlation coefficient (r) was used to find the correlation between canal diameter at different lumbar levels and walking distance in patients with LSS. RESULT: Pearson correlation coefficient (r) determined a fair positive correlation (r = 0.29) between lumbar canal diameter and walking distance. Stepwise multiple regression analysis was done, and a prediction equation was found for different levels of canal stenosis. CONCLUSION: Findings of our present study suggest a fair positive correlation between walking distance and canal diameter at L5-S1. This study may also be useful in predicting the approximate canal diameter by estimating the walking distance of the patient with symptoms of LSS and vice-versa.

INTRODUÇÃO: A claudicação neurogênica (CN) é a apresentação clínica clássica de pacientes com Estenose Espinhal Lombar (EEL). Esses pacientes podem ou não apresentar sintomas de dor nas pernas e dificuldade para caminhar. Esses sintomas são exacerbados ao caminhar e ficar em pé e são aliviados ao sentar ou inclinar-se para a frente. MÉTODO: Pacientes com EEL, com diâmetro do canal lombar ≤12mm, foram recrutados em um hospital terciário reconhecido. As características demográficas e antropométricas de cada sujeito foram anotadas e o procedimento do teste foi explicado. O diâmetro do canal foi documentado com a ajuda de um relatório de ressonância magnética. Um teste de caminhada individualizado foi usado para avaliar a distância percorrida. ANÁLISE ESTATÍSTICA: Dependendo da normalidade dos dados, o coeficiente de correlação de Pearson (r) foi usado para encontrar a correlação entre o diâmetro do canal em diferentes níveis lombares e a distância percorrida em pacientes com EEL. RESULTADO: O coeficiente de correlação de Pearson (r) determinou uma correlação positiva razoável (r = 0,29) entre o diâmetro do canal lombar e a distância percorrida. Análise de regressão múltipla stepwise foi feita, e uma equação de predição foi encontrada para diferentes níveis de estenose do canal. CONCLUSÃO: Os achados de nosso estudo sugerem uma correlação positiva razoável entre a distância percorrida e o diâmetro do canal em L5-S1. Este estudo também pode ser útil para prever o diâmetro aproximado do canal, estimando a distância percorrida pelo paciente com sintomas de EEL e vice-versa.

Validation of the Vancouver Symptom Score Questionnaire for bladder and bowel dysfunction for Brazilian children and adolescents

ABSTRACT Objective: This study aimed to translate, and perform a cross-cultural adaptation, and validation of the Vancouver Symptom Score (VSS) for bladder and bowel dysfunction (BBD) for Brazilian children and adolescents Materials and Methods: Six steps were performed for the translation and cross-cultural adaptation: (1) translation, (2) synthesis of translations, (3) back-translation, (4) pre-final version of the translated instrument, (5) pilot test and degree of comprehensibility and (6) elaboration of the Brazilian version of the VSS. For validation, the Brazilian Dysfunctional Voiding Score (DVSS) questionnaire was used. Results: Validation was performed on a sample of 107 children and adolescents with a mean age of 9.2 ± 2.84 years, presenting BBD and 107 without BBD (control group-CG). There was a positive correlation (r = 0.91, 95% CI 0.88 to 0.93, p < 0.0001) between total VSS score and total DVSS score. VSS was higher in patients with BBD (p < 0.0001). The internal consistency estimated by Cronbach's alpha was 0.87 for patients with BBD. The VSS showed excellent diagnostic accuracy in detecting cases, with an area under the ROC curve of 98% (95% CI 0.96 to 0.99, p < 0.001). A cut-off value of >11 points produced a sensitivity of 100% (95% CI 96.4% to 100%) and a specificity of 91.8% (95% CI 85.1% to 95.6%). Conclusion: The translated, cross-culturally adapted, and validated VSS for the Brazilian population is a reliable and valid tool to identify symptoms of BBD in children and adolescents aged five to 16 years, whose first language is Brazilian Portuguese.

Research advances of sacral neuromodulation in the management of pediatric neurogenic bladder / 现代泌尿外科杂志

Pediatric neurogenic bladder (PNB) is defined as dysfunction of the detrusor and/or urethral sphincter due to myelodysplasia or spinal cord injury, manifesting as impaired urination or defecation, which seriously affects the patients’ quality of life. The main indication for sacral neuromodulation (SNM) is overactive bladder syndrome, which presents as refractory urinary frequency and urgency, urgency incontinence and non-obstructive urinary retention. Age more than 16 years are also recommended for this technique. Previous studies have revealed that SNM could significantly improve the outcome of refractory bladder bowel dysfunction. This paper reviews the advances of the application of SNM in the treatment of pediatric neurogenic bladder so as to provide reference for pediatricians.

Application of three-dimensional printed guiding device for electrode implantation in sacral neuromodulation in children / 现代泌尿外科杂志

【Objective】 To investigate the application value of three-dimensional printed guiding device in sacral neuromodulation in children. 【Methods】 A total of 17 patients admitted during Jan.2017 and Nov.2022 were divided into two groups: control group (n=8), using traditional method to locate sacral foramen for puncture; three-dimensional printed guiding device group (n=5), using three-dimensional printing technology to make individual guiding device for puncture. The clinical indexes of the two groups were evaluated, including puncture time, puncture numbers, intraoperative X-ray exposure times, postoperative evaluation time and second-stage conversion rate. The evaluation indexes of postoperative complications were wound bleeding, wound infection, wound rupture, electrode fracture, displacement or prolapse. 【Results】 In the control group, 1 case was diagnosed as bladder-bowel dysfunction, the remaining 7 were neurogenic bladder; in the three-dimensional printed guiding device group, all 9 cases were diagnosed as neurogenic bladder. The puncture time was shorter in the three-dimensional printed guiding device group than in the control group [85(70-90) min vs.138(133-208) min], the puncture numbers were fewer [15(12-20) vs.22(18-26)], and the X-ray exposure times were fewer [12(12-17) vs.19(16-23)] (all P<0.05). The initial stimulation voltage, postoperative evaluation time and second-stage conversion rate were not statistically significant. 【Conclusion】 Compared with the traditional method, the use of three-dimensional printed guiding device can reduce the puncture numbers and shorten the puncture time in the process of sacral neuromodulation in children.

Important role of urodynamic study in improving the diagnosis and treatment of pediatric neurogenic bladder / 现代泌尿外科杂志

Of the common urinary dysfunctions in children, pediatric neurogenic bladder (PNB) is the most challengeable abnormality. It is well known that PNB is mostly caused by dysplasia of the lumbosacral spinal cord and nerves, which seriously affects the quality of life and the physical and mental health of children. The clinical symptoms are not obvious in minor cases, but severe upper urinary tract damage occurs in severe cases. Urodynamic study (UDS) is the best way to detect and determine the type of dysfunction at an early stage, and can guide the formulation of accurate and individualized treatment protocol. However, UDS in children has not been popularized in China, which seriously affects the level of diagnosis and treatment of PNB. This article reviews the importance of UDS so as to provide reference for the diagnosis and treatment of PNB.

Imaging urodynamic characteristics of lower urinary tract dysfunction in young male / 现代泌尿外科杂志

【Objective】 To analyze the results, characteristics and clinical value of video urodynamic study (VUD) of lower urinary tract symptoms (LUTS) in young male. 【Methods】 A total of 106 young male LUTS patients (18-45 years old) who received VUD in our hospital during Jan.2016 and Sep.2021 were collected to analyze the clinical and imaging urodynamic characteristics. 【Results】 Of the 106 patients, 55 (52.44%) had neurogenic lower urinary tract dysfunction (NLUTD)with clear neurological etiology, and 51 (48%) had non-neurogenic lower urinary tract dysfunction (NNLUTD). In NLUTD patients, dysuria was the most common symptom (76.74%); lumbosacral lesions were the main cause (76.36%); imaging urodynamics indicated weakening of detrusor muscle in different degrees. In NNLUTD patients,the main symptoms were frequent urination (48.72%) and dysuria (48.72%); about 58.97% of patients had two or more LUTS, and the main diagnosis was detrusor underactivity (DU)(35.90%). 【Conclusion】 NLUTD in young male is characterized by varying degrees of detrusor muscle weakness, detrusor sphincter dyscoordination, and decreased bladder compliance. NNLUTD is mostly caused by detrusor overactivity (DO) and DU.

Modified Sanpiantang Treats Nitroglycerin-induced Migraine in Rats via p38 MAPK/iNOS Signaling Pathway / 中国实验方剂学杂志

ObjectiveTo decipher the mechanism of modified Sanpiantang in the treatment of nitroglycerin-induced migraine in rats. MethodSeventy-two Wistar rats were randomized into the control， model （nitroglycerin， 10 mg·kg-1）， positive control （rizatriptan， 0.89 mg·kg-1）， and high- （12.96 g·kg-1）， medium- （6.48 g·kg-1）， and low-dose （3.24 g·kg-1） modified Sanpiantang groups. The rat model of migraine was established by intraperitoneal injection of 10 mg·kg-1 nitroglycerin. The behavioral test was carried out to measure the mechanical pain thresholds （MPT） of the periorbital region and hindpaw after successful modeling. The serum levels of nitric oxide （NO）， tumor necrosis factor-α （TNF-α）， interferon-γ （IFN-γ）， and interleukin-1β （IL-1β） in rats were determined by enzyme-linked immunosorbent assay （ELISA）. Immunohistochemistry （IHC） was employed to determine the expression of inducible nitric oxide synthase （iNOS） in the trigeminal nucleus caudalis （TNC）. Western blot was employed to determine the protein levels of iNOS and phospho-p38 mitogen-activated protein kinase （p-p38 MAPK） in the TNC. Real-time fluorescence quantitative polymerase chain reaction（Real-time PCR） was performed to measure the mRNA levels of iNOS， p38 MAPK， and IL-1β in the TNC. ResultCompared with the control group， the model group showed decreased MPT （P<0.01）， elevated serum levels of NO， TNF-α， IFN-γ， and IL-1β （P<0.01）， and up-regulated expression levels of p38 MAPK， iNOS， and IL-1β in the TNC （P<0.05， P<0.01）. Compared with the model group， modified Sanpiantang increased the MPT （P<0.05）， and the medium-dose group showed the most significant effect （P<0.01）. In addition， modified Sanpiantang down-regulated the mRNA levels of iNOS， p38 MAPK， and IL-1β and the protein levels of p-p38 MAPK and iNOS in the TNC of migraine rats （P<0.05， P<0.01） and lowered the serum levels of NO， TNF-α， IFN-γ， and IL-1β （P<0.05， P<0.01）. ConclusionModified Sanpiantang may treat migraine by down-regulating the expression of pro-inflammatory factors such as NO， TNF-α， IFN-γ， and IL-1β in the p38 MAPK/iNOS signaling pathway to reduce the neurogenic inflammation.

Changes of bladder morphology and function and effect on upper urinary tract dilatation at different time after lumbosacral nerve transecting in rats / 中华泌尿外科杂志

Objective:To investigate the changes in the morphology, structure and function of the bladders and their effects on the upper urinary tract dilatation(UUTD) after lumbosacral nerve transecting in rats.Methods:A total of 45 female SD rats were included, randomly divided into 3 groups with 15 rats in each group. Two groups were performed bilateral lumbar 6(L6) and cauda equina nerve shearing to establish neurogenic bladder(NB) model, which were nerve transected for 4 weeks(NB-4W) group and nerve transected for 12 weeks(NB-12W) group. Another group was performed bilateral L6 nerves and cauda equine exposing but not transecting, which was sham-operation (Sham) group. Cystometry and renal ultrasound examination were performed and rats in each group were killed to collect the kidney and bladder tissues in NB-4W group at 4 weeks, in Sham group and NB-12W group at 12 weeks after operation. HE, Masson staining, immunohistochemical staining and western blot were used to detect histological changes, expression of transforming growth factor-β1(TGF-β1) and α-smooth muscle actin(α-SMA).Results:All rats in NB-4W and NB-12W group showed acontractile detrusor. In the NB-4W and NB-12W group, the maximum cystometric capacity [(5.84±0.33) ml and (3.13±0.35) ml], the detrusor leak point pressure [(25.41±0.86) cm H 2O and (27.36±2.04) cm H 2O] (1 cm H 2O = 0.098 kPa), were significantly higher than those in the Sham group [(0.98±0.14) ml, (7.13±0.90) cm H 2O, both P<0.05]. Compliance in NB-4W group [(0.28±0.21) ml/cm H 2O] and NB-12W group [(0.17±0.12) ml/cm H 2O] were significantly lower than that of the Sham group [(0.34±0.26) ml/cm H 2O], and the compliance of NB-12W group was lower than that of NB-4W group significantly (all P<0.05). HE staining of the bladder showed that the inflammatory cell infiltration was obvious in the NB-4W and NB-12W group. Bladder collagen volume fractions in NB-4W group [(30.5±1.5) %] and NB-12W group [(45.2±3.8) %] were both higher than that of Sham group [(20.7±2.2) %, both P<0.05]. The expression of TGF-β1 and α-SMA in the bladder tissue of NB-4W group were higher than those of sham group, and that of NB-12W group were higher than NB-4W group. In NB-4W group and NB-12W group, 3 (20.0 %) and 7 (46.7 %) rats were found hydronephrosis, respectively. Additionally, HE staining showed that the degree of renal tubule injury and the number of inflammatory cell infiltration in the NB-4W and NB-12W group were higher than those in the Sham group. Masson staining showed that the volume fraction of collagen in kidneys of NB-4W and NB-12W group were (13.1±1.4) % and (21.6±1.9) %, respectively, which were significantly higher than that in sham operation group [(4.6±0.7) %, both P<0.05]. Conclusions:Bilateral L6 + cauda equina nerve transecting can induce NB with hydronephrosis in parts of rats. The degree of bladder fibrosis gradually increased with the time of nerve transection, and the incidence and severity of UUTD also increased with the time of nerve transection.

Analysis of the effect of one-stage transurethral prostatectomy for benign prostatic hyperplasia accompanied by non-neurogenic detrusor acontractility / 中华泌尿外科杂志

Objective:To investigate the safety and efficacy of one-stage transurethral prostatectomy for prostatic hyperplasia accompanied by non-neurogenic detrusor acontractility.Methods:The clinical data of 35 patients with benign prostatic hyperplasia accompanied by non-neurogenic detrusor acontractility admitted to The Second Affiliated Hospital of Zhengzhou University from January 2015 to Octorber 2021 were analyzed.The average age was (74.0±7.9) years old. The average volume of prostate was (77.8±44.5)cm 3. The average total prostate specific antigen(tPSA)was(8.9±8.7)ng/ml. The preoperative international prostate symptom score(IPSS) was (19.1±4.3) and the preoperative quality of life score(QOL)was 5(5, 5). All the patients were treated with one-stage transurethral prostatectomy and suprapubic cystostomy. After removing the cystostomy tube, the post-void resident volume(PVR), the maximum urine flow rate(Q max), IPSS, QOL were recorded, and complications were followed up. Successful treatment is defined as the removal of the cystostomy tube without worsening of upper urinary tract hydronephrosis. Results:All the operations were successfully completed. The success rate of treatment was 85.7%(30/35), and the median time to resume spontaneous urination was 4.0(3.3, 4.5) weeks. The average postoperative Q max was (12.6±2.3)ml/s, and the average PVR was(27.7±9.5)ml. The postoperative IPSS was (5.5±2.4), which was significantly improved compared to preoperative( P<0.001). The postoperative QOL score was 1(1, 2) points, which was significantly lower than preoperative( P<0.001). The patients voiding spontaneously were followed up for 3-69 months, and no complications such as urinary retention, recurrent urinary tract infection and hydronephrosis occurred. Conclusions:One-stage transurethral prostatectomy for patients with benign prostatic hyperplasia accompanied by non-neurogenic detrusor acontractility has a high success rate and few complications, which greatly improves the quality of life of patients.

Objective:To examine differences in urodynamic changes between central neurogenic bladder(CNB)and peripheral neurogenic bladder(PNB)in elderly patients.Methods:A total of 57 elderly patients over 60 years old with neurogenic bladder(NB)were divided into a CNB group and a PNB group based on the types of nerve injuries.Data on urodynamic parameters recorded for the two groups were compared and analyzed.Results:The rate of detrusor overactivity(DO)in the CNB group was significantly higher than that in the PNB group [66.7%(16/24)vs.36.4%(12/33), χ2=5.105, P=0.024]. There were significant differences between the two groups in maximum bladder capacity(MCC)[(277.8±101.1)in the CNB group vs.(481.4±110.2)ml in the PNB group, t=-7.149, P=0.001]and in safe bladder capacity(SBC)[(283.2±28.8)ml in the CNB group vs.(348.6±33.9)ml in the PNB group, t=-7.636, P=0.000]. There was no significant difference between the two groups in the maximum urine flow rate, residual urine volume, urination volume, leak point pressure, or detrusor pressure at the maximum urine flow rate(all P>0.05). In the CNB group, 8 patients had normal bladder sensation, 4 had disappeared bladder sensation, 10 had decreased sensation, and 2 had increased sensation.In the PNB group, 9 patients had normal bladder sensation, 4 had disappeared bladder sensation, 14 had decreased sensation, and 2 had increased sensation.There was no statistical significance in SBC between different sensation levels within each group( P>0.05). Conclusions:There are differences in urodynamic characteristics between the elderly patients with CNB and those with PNB.Decreases in MCC, SBC and DO are more likely to occur in CNB.

Effect and Mechanism of Cuscutae Semen Total Flavonoids Combined with Tripterygium wilfordii Polyglycoside Tablets on Ovarian Germline Stem Cells of Physiological Mice by Notch Signaling Pathway / 中国实验方剂学杂志

ObjectiveTo observe the effect of Cuscutae Semen total flavonoids combined with Tripterygium wilfordii polyglycoside tablets （TWPT） on ovarian germline stem cells of female physiological mice through neurogenic locus notch homolog （Notch） signaling pathway. MethodSixty female Kunming mice （5 weeks old） were randomly divided into normal group， Tripterygium wilfordii polyglycoside tablets low-， high-dose groups （13.65 mg·kg-1·d-1 and 27.3 mg·kg-1·d-1， 1 and 2 times clinical equivalent dose）， Cuscutae Semen total flavonoids low- and high-dose groups （150 mg·kg-1·d-1 and 300 mg·kg-1·d-1）， and combination group （13.65 mg·kg-1·d-1 TWPT and 150 mg·kg-1·d-1 Cuscutae Semen total flavonoids）， with 10 in each group. After 3 weeks of continuous administration， the uterus/brain and ovarian/brain indexes were calculated， and the pathological changes of ovarian tissue were observed under light microscope. The content of estradiol in serum was determined by enzyme linked immunosorbent assay （ELISA）. Immunofluorescence assay was performed to observe the expressions of germline stem cell markers in ovarian epithelium， including mouse vasa homologue （Mvh）， octamer-binding transcription factor 4 （Oct4）， tyrosine-protein kinase receptor （c-kit）， Nanog， Notch signaling pathway molecules， neurogenic locus notch homolog protein 1 （Notch1）， hes family BHLH transcription factor 1（Hes1）， and jagged canonical Notch ligand 1 （JAG1）. ResultCompared with the normal group， low and high doses of TWPT had no significant effect on the uterus/brain and ovary/brain indexes and the uterus and ovary morphologies of mice， while only the number of atretic follicles was increased （P<0.01）. The expressions of ovarian germline stem cell markers and Notch signaling pathway molecules had a decreasing trend in TWPT low-dose group， while the expressions of Mvh， c-kit， and Nanog were down-regulated （P<0.05， P<0.01） and the expressions of Notch1 and Hes1 were also reduced （P<0.01） in TWPT high-dose group. However， the above indexes were increased in Cuscutae Semen total flavonoids low-dose group （P<0.05， P<0.01）. Compared with the low does of TWPT group， the combination group had a decrease in the increased number of atretic follicles （P<0.01）， an improvement in the down-regulated expressions of Mvh and Nanog （P<0.01）， and an increase in the expressions of Notch1 and Hes1 （P<0.05， P<0.01）. ConclusionOvarian germline stem cells are the source target of the reproductive toxicity of TWPT. Cuscutae Semen total flavonoids participate in the regulation of the germline stem cell pathways to alleviate the reproductive toxicity caused by TWPT， and its mechanism of action may be related to the Notch signaling pathway.

Advances in corneal nerve regulation of ocular surface microenvironment / 国际眼科杂志(Guoji Yanke Zazhi)

The cornea is a transparent outer layer of the anterior eye segment, innervated by a high density of neural tissue. In the process of corneal innervation, trigeminal ganglion originated corneal nerves traverse different types of corneal cell in the epithelial and stromal layers. Corneal stromal cells, epithelial cells, immune cells, and other cells interact closely to maintain corneal microenvironmental homeostasis. In addition, corneal nerves is associated with the occurrence and development of many ocular surface diseases. Corneal nerves release various active peptides that regulate corneal sensation, maintain epithelial integrity and proliferation, improve wound healing, and manage local inflammation and immune response. This article reviews the advances in the corneal nerve regulation of the ocular surface microenvironment, providing some new ideas for the further study and treatment of corneal nerve-associated diseases.

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.
