ABSTRACT
Objective:To develop an improved wireless intelligent capsule cystoscope (WCE)for dynamic detection of bladder mucosa in a pig model.Methods:The WCE was introduced into a healthy experimental pig that under general anesthesia via urethra by applying an improved device. Multi-angle images of the bladder mucosa were then obtained by controlling the position of capsule cystoscope with an external magnetic field system. The shutter speed of the WCE was 2.5 fps and was automatically converted to 1.5 fps 30 minutes after initiation. The Vue software was utilized to download the shoot pictures which were former received by a computer via wireless transmission. The pig was roused and sent to the pigpen, without limitations in moving. The improved WCE was connected with a 2 cm thread. 12 hours later, the dilated sheath was inserted again, and the capsule was removed by a foreign body forceps under observation of a ureteroscopy.Results:The WCE was successfully placed and removed from the pig's bladder with the application of the improved devices. Over 20 thousand images that with 60K pixels of bladder mucosa were captured by the WCE at various angles within 12 hours, which revealed the process of urine filling and excreting in a time-dependent way. No notable adverse effects (bleeding, urinary tract injury, etc) were noted during the process of cystoscope placement, image acquisition, transmission, and removal.Conclusion:This study developed a novel WCE that could dynamically, intelligently and accurately monitor all aspects of the pig bladder mucosa, and has preferable application prospect.
ABSTRACT
Septic cardiomyopathy is one of the most common complications of sepsis in clinics. Up to now, the pathogenesis of septic cardiomyopathy has not been fully elucidated, and the clinical mortality has been at a relatively high level in patients with organ injury caused by sepsis, so that improving the cardiac dysfunction and myocardial injury of septic patients is of great significance in improving their prognoses. In this article, the related literatures regarding the research and therapeutic progress of septic cardiomyopathy in traditional Chinese and western medicine in recent years were read and summarized.
ABSTRACT
@#Post-stroke depression often seriously affects the prognosis and quality of life of patients and many clinical trials had shown that Chai Hu Shu Gan San (柴胡疏肝散) combined with selective serotonin reuptake inhibitors (SSRIs) had good efficacy and minor side effects. We aimed to conduct this metaanalysis to evaluate the efficacy and safety of Chai Hu Shu Gan San as an adjuvant drug for SSRI in treating post-stroke depression. We searched PubMed, EMBASE, Cochrane Library, Wanfang, China Biology Medicine disc (CBM), Chongqing VIP, and CNKI (China National Knowledge Infrastructure) from their date of foundation to December 15, 2018. Literature screening, data extraction and quality assessment were conducted by two authors independently. The data synthesis and analysis were performed by using Review Manager (RevMan) 5.3 software and sensitivity analysis was conducted to assess the robustness of the results. Finally, a total of 22 articles were included. The meta-analysis confirmed the advantages of the combination of SSRI and Chai Hu Shu Gan San, mainly from four aspects: the Hamilton Depression (HAMD) scale score (MD=3.66; 95% DI=2.33-4.98; p<0.001), the Modified Edinburgh Scandinavian Stroke Scale (MESSS) score (MD=4.87; 95% CI=2.32-7.43; p<0.001), the efficacy rate (OR=3.50; 95% CI =2.61-4.69; p<0.001) and the incidence of adverse reactions (OR=0.28; 95% CI=0.17-0.46; p<0.001). No significant publication bias was observed, and sensitivity analysis suggested a good stability of the results. According to the present evidence, we concluded that Chai Hu Shu Gan Sa
ABSTRACT
Cerebral autosomal dominant arteriopathy with subcortical infarcts and leucoencephalopathy(CADASIL)is a common hereditary disease caused by NOTCH3 gene. The major clinical manifestations includerecurrent small-vessel ischaemic events, migraine, dementia and mood disturbance. Herein, wereport a 32-years-old male presented with right leg weakness and persistent migraine. We carried outneurological exams, genetic testing, blood and cerebrospinal fluid analysis (CSF) as well as magneticresonance imaging (MRI) for the brain and spinal cord. There were no anti-aquaporin-4 antibodiesand oligoclonal bands in the CSF and blood investigations were within the normal range. MRI scansrevealed multiple hyperintense regions in the brain and longitudinally hyperintense signal in spinal cord.Further, we identified a c.383G>A(p.Cys128Tyr) mutation in NOTCH3 gene. Therefore, the patientwas diagnosed with CADASIL concurrent with spinal cord lesion. The patient’s condition slightlyimproved after two weeks treatment with daily dosage of 0.5 g citicoline and 75 mg clopidogrel.
ABSTRACT
Hereditary spastic paraplegia is a heterogeneous group of genetic neurodegenerative disorders of the nervous system. It is classified into four subtypes based on the mode of inheritance; and among them, most autosomal recessive hereditary spastic paraplegia cases are due to type SPG11 and SPG15 gene mutations. Autosomal recessive hereditary spastic paraplegia cases with SPG30 gene mutation have never been reported in China. Herein, we present our experience with a case of hereditary spastic paraplegia with SPG30 gene mutation in our hospital from North East China. In this patient we detected a missense mutation of c.499 C>T (p.Arg167Cys) in gene KIF1A, a causative gene of type SPG30.

In the western medication group, tamsulosin capsules 0. 2 mg were prescribed for oral administration, once a day; indometacin sustained release tablets, 25 mg, three times a day. Totally, the oral administration for 8 weeks was required. In the catgut embedding group, the acupoint catgut embedding therapy was applied to Qugu (CV 2), Shenshu (BL 23), Zhibian (BL 54), Huiyin (CV 1) and Sanyinjiao (SP 6), once every two weeks; the treatment of 4 weeks made one session, and two sessions were required. Before and after treatment, TCM symptom score, NIH-CPSI (the National Institute of Health Chronic Prostatitis Symptom Index) score, lecithin body numbers in prostatic fluid, score in SAS (self-rating anxiety scale), score in SDS (self-rating depression scale), the levels of SP and β-EP, etc. were observed in the two groups, and the clinical efficacy was assessed in the two groups.</p><p><b>RESULTS</b>(1) Ten cases were dropped in either group. The total effective rate was 91. 25% (73/80) in the catgut embedding group, higher than 78. 75% (63/80) in the western medication group (P<0. 05). (2) After treatment, TCM symptom score, total score in NIH-CPSI, pain score and the scores in SAS and SDS were all reduced as compared with those before treatment in the two groups (all P<0. 05). After treatment, TCM symptom score, total score and pain score in NIH-CPSI, and the scores in SAS and SDS in the catgut embedding group were both lower than those in the western medication group (all P<0. 05). (3) After treatment, the lecithin body numbers were both increased as compared with those before treatment in the two groups (both P<0. 05), and the result in the catgut embedding group was higher than that in the western medication group (P<0. 05). (4)After treatment, the SP level was lower than that before treatment in the two groups (both P<0. 05); the level of p-EP was increased as compared with that before treatment (both P<0. 05). The SP level in the catgut embedding group was lower than that in the western medication group (P<0. 05); the level of β-EP was higher than that in the western medication group (P<0. 05).</p><p><b>CONCLUSION</b>The acupoint catgut embedding therapy apparently relieves the clinical symptoms of chronic pelvic cavity pain syndrome differentiated as kidney deficiency and stagnation of damp heat as well as the condition of anxiety and depression, increases lecithin body numbers in prostatic fluid and β-EP level and reduces SP level.</p>

ABSTRACT
Objective To study the effectsof rehabilitative training on neural function and the expression of glial fibrillary acidic protein (GFAP) and ionized calcium binding adaptor molecule-1 (Iba-1) in rats after traumatic brain injury.Methods A left hemisphere traumatic brain injury model was established in ninety Sprague-Dawley rats.They were then randomly divided into a rehabilitation training group,an immobilization group and a free-running group,with 30 rats in each group.Another thirty rats received sham injury as the shamoperated group.Beginning 4 days post-operation the rats of the rehabilitation training group were given balancing,rotating and walking exercises three times daily,15 min/time,6 d/week.The immobilization group was fixed in mesh cages.The rats of the free-running and sham-operated groups were reared in normal cages without any special training exercise.The rats of all 4 groups were given neural and motor function tests to assess the functional outcome.Immunofluorescence staining was used to evaluate the expressions of GFAP (the marker of astrocytes) and Iba-1 (the marker of microglia) in the cortex close to the iujured region at 3 days,1 week,2 weeks,3 weeks and 4 weeks after injury.Results The average neural and motor function test scores in the rehabilitation training group were significantly better than those in the immobilization and free-running groups at the 2nd week and thereafter.The average scores in the free-running group were significantly better than those in the immobilization group at the 4th week after injury.The immunofluorescence staining showed that the expression of GFAP was lowest in the rehabilitation group at the 2nd week and thereafter.Iba-1 expression was significantly lower only at the 3rd week and beyond.Conclusion Rehabilitative training can improve nerve function recovery in rats after traumatic brain injury,and the functional enhancement may be partially attributed to the downregulation of activated astrocytes and microglia.
ABSTRACT
Objective To study the clinical efficacy and adverse reactions of the preoperative neo-adjuvant chemotherapy with oxaliplatin plus fluorouracil and calcium folinate (FOLFOX) in the treatment of advanced gastric carcinoma that was difficult to undergo radical operation. Methods We enrolled 16 patients with advanced gastric carcinomas that were unable to undergo radical operation admitted to our hospital from April 2008 to October 2009. The neo-adjuvant chemotherapy regimen was oxaliplatin 130 mg/m~2 for first one, fluorouracil 500 mg/m~2 and calcium folinate 200 mg/m~2 from first day to fifth day,and one treatment course was three weeks and the patients underwent two courses.The changes of the primary lesion and the adverse reactions of the patients were observed. Results Carcinomas of 13 patients were degraded after the treatment, of which, 11 patients underwent radical resections after 4-6 weeks after operation.There were two cases of complete remission (CR) , 10 cases of partial remission (PR), three cases of stable disease(SD) and one case of progress disease(PD) , and the total effective rate was 75.0% (12/16). Adverse reactions included bone marrow suppression, diarrhea, nausea and vomiting and paresthesia, which were relieved after appropriate symptomatic treatment. Conclusions Neoadjuvant chemotherapy with FOLFOX can improve the resection rate of the advanced gastric carcinoma that is unable to undergo radical resection, and the patients' tolerability to this regimen is favorable.Thus, the regimen is worthy of generalizing.
