ABSTRACT

A case of polyarteritis nodosa was reviewed. The patient was a 58-year-old middle-aged man. He developed fever, headache, fatigue and other symptoms. Three weeks after, massive hematuria was seen. CT plain scan and MRI indicated blood clots in renal pelvis, and pericardium and pleural effusion. Renal arteriography indicated multiple venous fistula in both kidneys. Enhanced CT scan showed multiple small aneurysms in abdominal aortic branches, bilateral renal arteries and pancreatic arteries. The diagnosis of nodular polyarteritis was confirmed. Glucocorticoid and immunosuppressive agents were given. Meanwhile, highly selective renal arteriovenous fistula embolization was performed, Postoperative hematuria was effectively controlled, and the general condition was gradually improved. The patient was followed up for 2 months, and the condition was stable.

ABSTRACT

@#At present , methamphetamine has become a major hidden danger in global public health safety. In order to judge methamphetamine addicts and methamphetamine abstainers more scientifically and reliably, this study analyzed the endogenous metabolites in plasma, serum and urine of methamphetamine addicts, methamphetamine abstainers and healthy volunteers by highly sensitive high-throughput liquid chromatography quadrupole time-of-flight mass spectrometry (LC-QTOF-MS) analytical instrument. The obtained metabolomic data were processed by univariate analysis (t-test) and multivariate analysis (PLS-DA and OPLS-DA) and eligible potential biomarkers were then screened.The identified biomarkers set enrichment analysis to find the connection between metabolites and metabolic pathways.Multivariate statistical results showed that methamphetamine acute group, recovery group and healthy group were clearly separated.3, 18 and 6 regulated metabolites were identified in serum, plasma and urine, respectively, suggesting that lipid metabolism was abnormal in methamphetamine acute group, and that fatty acid metabolism, sulfate/sulfite metabolism and sex hormone metabolism were abnormal in methamphetamine recovery group.The selected potential biomarkers in this study provide the possibility for scientific judgment of the clinical stage of methamphetamine detoxification.

ABSTRACT

@#Background & Objective: Disease-modifying treatments (DMTs) for multiple sclerosis (MS) are widely used in Western countries. In China, however, the current treatment patterns of MS patients are not well characterized. This is to explore the gap between the current treatments in Guangzhou, Southern China and those given in Western countries. Methods: We performed a survey of MS patients at department of neurology, a tertiary MS referral centre in Guangzhou, concerning treatments of MS in Southern China. The clinical data in patients were collected. The initial treatment, drug withdrawal or switching profile, and therapeutic effect of existing treatments in MS patients were analyzed. Results: The ratio of MS patients who receive DMTs in Guangzhou China is extremely low. Among the 178 patients studied, only 28.09% received initial treatment with DMTs. MS patients who receive initial treatment with first-line DMTs have higher drug withdrawal rates (32.6%) and drug switching rates (30.43%) than those of western populations. The main reasons for withdrawal of first-line DMTs were doctor’s advice (maintenance of remission) (40.00%), economic burden(20.00%), and no channels to buy drugs(13.33%). In MS patients initially treated with first-line DMTs who switched to other drugs, a gap between treatments was common (8/14;57.14%). There were 18 patients with highly active MS receiving treatment with rituximab. Annual relapse rate after treatment significantly decreased than that before treatment (0.74 vs. 1.50 , P < 0.001). Conclusions: DMTs for MS in Guangzhou, Southern China appear to lag behind those in Western countries. Much work is needed to improve drug accessibility and affordability of DMTs in China. Rituximab is an option for highly active MS in limited medical-resource countries.

ABSTRACT

Objective@#To explore the incidence and influencing factors of child emotional neglect, and to provide evidence for the relevant departments to prevent child emotional neglect.@*Methods@#Stratified random cluster sampling method was used to select 1 354 parents from a county of Henan Province. Anonymous questionnaire survey was conducted among them to investigate child emotional neglect, logistic regression analysis was used to analyze the influencing factors of emotional neglect.@*Results@#The total incidence of child emotional neglect was 15.7%, and the rate of boys and girls was 14.7% and 16.8%, respectively, that of fathers and mothers was 18.3% and 15.1%, respectively. There were no statistically significant differences in rates between fathers and mothers’ emotional neglect behaviors, neither between boys and girls (χ2=1.18,3.14, P>0.05).90.2% parents could often/always console children when they were hurt or feared. Multivariate logistic regression analysis showed that risk factors of high emotional neglect incidence included living in rural areas, poorer family economic status, parents with lower social support and childhood neglect experience, biological parents are not married(OR=2.71, 2.56, 2.64, 2.66, 4.11, 1.76, P<0.05).@*Conclusion@#Parents’ emotional neglect of kindergarten children existed in the research area, attention should be paid to the emotional neglect of parents from rural areas, and parental education activities should be carried out to enhance parents’ parenting skills.

ABSTRACT

Immunoglobulin G against myelin oligodendrocyte glycoprotein (MOG-IgG) is detectable in neuromyelitis optica spectrum disorder (NMOSD) without aquaporin-4 IgG (AQP4-IgG), but its pathogenicity remains unclear. In this study, we explored the pathogenic mechanisms of MOG-IgG in vitro and in vivo and compared them with those of AQP4-IgG. MOG-IgG-positive serum induced complement activation and cell death in human embryonic kidney (HEK)-293T cells transfected with human MOG. In C57BL/6 mice and Sprague-Dawley rats, MOG-IgG only caused lesions in the presence of complement. Interestingly, AQP4-IgG induced astroglial damage, while MOG-IgG mainly caused myelin loss. MOG-IgG also induced astrocyte damage in mouse brains in the presence of complement. Importantly, we also observed ultrastructural changes induced by MOG-IgG and AQP4-IgG. These findings suggest that MOG-IgG directly mediates cell death by activating complement in vitro and producing NMOSD-like lesions in vivo. AQP4-IgG directly targets astrocytes, while MOG-IgG mainly damages oligodendrocytes.

ABSTRACT

Objective To explore the method and clinical value of sentinel lymph node biopsy for penile carcinoma guided by multispectral separate-merge guided surgery device (MGS).Methods The clinical data of 7 patients with sentinel lymph node biopsy of penile cancer guided by MGS from April 2017 to April 2018 were analyzed retrospectively at First Hospital of Shanxi Medical University.They were 62-78 years old,with an average age of 65 years.All of carcinoma was located in the glans or coronal sulcus,which diameter was 1.0-3.5 cm,with an average of 2.5 cm.Three cases of inguinal lymph nodes could be non-palpable and the others palpable.All patients were injected 0.25 ml (2.5 mg/ml) of indocyanine greensolution with 1 ml syringe at 12,4,6 and 9 points in the proximal normal skin of penile tumors.Immediately,the imaging probe was aligned with the injection point to observe the dynamic changes of fluorescence image on MGS display.Results There were 14 sides of groin in 7 patients,except for 1 side without images,other 13 sides developed well.The images displayed by MGS include visible image,fluorescent image and merged image,and the merged image was green pseudo color.According to the dynamic changes of the image,it could be divided into five parts:injection point,penile body,pubic symphysis,inguinal region and sentinel lymph node.In 13 well-developed sides,fluorescence gradually disappeared in other parts about 15 minutes after injection,and the location of sentinel lymph nodes was determined in vitro by gradually consolidating and fixing the fluorescence images in the inguinal region.The lymph node-like tissue with strong fluorescence intensity was observed immediately after the skin incision.There was a clear boundary between the lymph node-like tissue and the surrounding tissue.Along this boundary,lymph nodes were separated,ligated,excised.No lymph nodes were found on the undetected side.Postoperative pathology confirmed that lymph nodes were located by fluorescence imaging in vitro and traced by fluorescence imaging in vivo,the coincidence rate was 100%.There were residual fluorescent tissues on three sides and lymphatic vessels were removed.Conclusions MGS-assisted intraoperative fluorescence imaging could improve the doctor's visual depth so that physicians can real-time,dynamic,accurate in vitro location and in vivo tracking of sentinel lymph nodes of penile cancer.

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the value of the diagnostic criteria for bladder outlet obstruction in benign prostatic hyperplasia (BPH).</p><p><b>METHODS</b>A total of 358 patients with BPH were divided into 3 grades according to fibrous urethrocystoscopy information on the severity of obstructions, which were classified as Grade 1 (slight), Grade 2 (moderate), and Grade 3 (severe). By Schäfer's graph they were divided into 7 grades, represented by 0 to VI. We analyzed the volume of prostate, maximum flow rate (Qmax), residual urine volume, International Prostatic Symptom Score (IPSS) and detrusor instability. Statistical analysis ANOVA (analysis of variance) was made, spearman correlation evaluated and the coefficient of determination measured.</p><p><b>RESULTS</b>Of all the patients, 27 were classified as Grade 1, 236 as Grade 2 and 95 as Grade 3. Eighty-four patients had detrusor instability. The volumes of the prostate ranged from 16 ml to 145 ml, averaging (47.04 +/- 15.61) ml. The mean maximum flow rate was (10.02 +/- 2.12) ml/min and the mean residual urine volume was (84.06 +/- 36.50) ml. With the increase of the severity of obstruction, the volume of the prostate increased (F = 4.216, P < 0.05), IPSS rose (F = 8.408, P < 0.001), the maximum flow rate decreased (F = 22.43, P < 0.001), the residual urine volume rose (F = 163.232, P < 0.001), the incidence of detrusor instability increased (F = 23.637, P < 0.001) and Schäfer's grades were elevated (F = 202.897, P < 0.001). The volume of the prostate, the maximum flow rate (Qmax), residual urine volume, IPSS detrusor instability and Schäfer's grades were all correlated significantly with the severity of the obstruction. The correlation index and coefficient of determination were r = 0.29, R2 = 0.08; r = 0.35, R2 = 0.12; r = -0.69, R2 = 0.47; r = 0.60, R2 = 0.36; r = 0.33, R2 = 0.11; r = 0.72, R2 = 0.52; respectively. The correlation between the urethrocystoscopy information and Schäfer's graph on the severity of the obstruction were the best criteria of all.</p><p><b>CONCLUSION</b>The severity of the obstruction at urethrocystoscopy correlates well with that at urodynamic investigation. Such criteria could improve the sensitivity and specificity of the diagnosis of bladder outlet obstruction.</p>
