Objective To investigate the clinical efficacy of fire needling plus moxibustion in treating prurigo nodularis. Methods Ninety patients with prurigo nodularis were randomly allocated to treatment and control groups, 45 cases. The treatment group received fire needling plus moxibustion and the control group, external application of halometasone ointment. Skin lesions and pruritus were scored in the two groups before and after treatment. The clinical therapeutic effects were compared between the two groups. Results There were statistically significant pre-/post-treatment differences in the skin lesion score and the pruritus score in the two groups (P<0.01,P<0.05). There were statistically significant post-treatment differences in the skin lesion score and the pruritus score between the treatment and control groups (P<0.01). The total efficacy rate was 81.8% in the treatment group and 60.5% in the control group; there was a statistically significant difference between the two groups (P<0.05).Conclusion Fire needling plus moxibustion is an effective way to treat prurigo nodularis.

AIM:To observe the characterization in neural cells derived from the hippocampus of embryonic rats and to examine the effect of myelin-associated glycoprotein(MAG) on the proliferation,differentiation and neurite growth of neural stem cells(NSCs).METHODS:The hippocampus cells of embryonic rats were isolated and cultured in vitro.The expressions of nestin and doublecortin,the marks of NSCs,were observed by immunocytochemical method.The rate of proliferating cells was examined by BrdU immunocytochemistry.The average neuronal neurite length and the percentage of differentiated neurons were detected by immunocytochemistry staining.RESULTS:The hippocampus cells of 16 days old embryonic rats had the characteristics of NSCs.The percentage of differentiated neurons(?-tubulin Ⅲ-positive cells) was 18.17%?2.79% and the average neuronal neurite length was(136.27?33.66)?m,seven days after the differentiation initiated in vitro in control group.After NSCs were treated with MAG-Fc(200 ?g/L),the percentage of differentiated neurons and the average neurite length were decreased,respectively,to 10.05%?3.42%(P0.05).CONCLUSION:MAG-Fc inhibits the differentiation and neurite growth of the NSCs,but has no effect on the proliferation.

Background: and Purpose: Contrast enhancement of the oculomotor nerve in MRI was recently noticed in patients with clinical ischemic isolated oculomotor nerve palsy (iIONP). The opinions about whether this is a sign of inflammation and whether or not to administer steroids vary between doctors. The study aimed to determine the associations between this enhancement and vascular-disease risk factors (VRFs) and inflammatory factors in iIONP patients. Methods: The study recruited patients who had experienced iIONP during the previous 2 years. They were divided into groups A and B based on whether or not they exhibited an enhanced oculomotor nerve in MRI of the cavernous sinus using thin-section, fat-suppressed, and contrast-enhanced sequences. VRFs, inflammatory factors, and improvement scores were compared between the two groups. Results: Most (71.1%) of the 45 included iIONP patients had enhanced oculomotor nerves in MRI. VRFs, periorbital pain, elevated C-reactive protein and erythrocyte sedimentation rate, the neutrophil-to-lymphocyte ratio, and the platelet-to-lymphocyte ratio were not significantly associated with the enhancement. Four of the five patients in group A exhibited an elevated cerebrospinal fluid (CSF) IgG synthesis rate. The improvement score of eight patients who received 80 mg of methylprednisolone in addition to the routine therapy was not significantly different from the scores of the other patients (p=0.485). Conclusions More than half of the iIONP patients had an enhanced oculomotor nerve in MRI. A few of them also had elevated CSF IgG synthesis rate, but no further evidence for inflammation was found. The administration of steroids seemed to have no benefit other than increasing the blood glucose level.

Objective To investigate the clinical outcomes of percutaneous kyphoplasty (PKP) for treatment of vertebral compression fractures in perimenpausal women.Methods A total of 53 perimenopausal patients (70 vertebrae) undergone PKP for vertebral compression fractures from January 2007 to May 2014 were analyzed retrospectively by case-control study.Thirty-six patients had single vertebral fractures and 17 two-level vertebral fractures.The fracture segments included 5 T11 vertebrae,14 T12 vertebrae,30 L1 vertebrae,12 L2 vertebrae and 9 L3 vertebrae.Ratio of vertebral compression was 10％-30％.According to treatment difference,the patients were divided into PKP group and non-operation group.In PKP group,there were 30 patients with age range of 44-54 years (mean,51.0 years),and the fracture segments included 13 T11 vertebrae,11 T12 vertebrae,17 L1 vertebrae,7 L2 vertebrae,3 L3 vertebrae.In non-operation group,there were 23 patients with age range of 44-54 years (mean,50.5 years),and the fracture segments included 2 T11 vertebrae,3 T12 vertebrae,13 L1 vertebrae,5 L2 vertebrae,6 L3 vertebrae.Visual analogue scale (VAS),Oswesty disability index (ODI),vertebral compression rate,Cobb angle and bone mineral density change were compared preoperatively,2 weeks,6 months and 3 years after operation.Results All patients were followed up for 6-36 months.VAS and ODI were improved compared with preoperative status in two groups at 2 weeks,6 months and 3 years (P ＜ 0.01).VAS and ODI in PKP group were significantly decreased at 2 weeks and 6 months compared with non-operation group (P ＜ 0.01).The Cobb angle and vertebral compression rate in non-operation group were improved at 6 months compared with those in preoperative status (P ＜ 0.05),and a consistent increase was noted at 3 years,but the difference was not statistically significant (P ＞ 0.05).The Cobb angle and vertebral compression rate in PKP group were reduced at 6 months compared with preoperative status (P ＜ 0.05),and an increase was noted at 3 years,but the difference was not statistically significant (P ＞ 0.05).The Cobb angle and vertebral compression rate in PKP group did not increase at 6 months and 3 years,but they had significant increase in non-operation group (P ＜ 0.05).The body mass index in non-operation group decreased at different degrees at 6 months and 3 years,compared with preoperative status (P ＜ 0.05),while the body mass index reduction in PKP group had no statistically significant difference (P ＞ 0.05).The body mass index reduction in PKP group was less than that in non-operation group at 3 years (P ＜0.01).The body mass index reduction in PKP group was slow and had no statistically significant difference compared with preoperative status (P ＞ 0.05).The body mass index reduction in non-operation group was fast and had significant decrease compared with preoperative status (P ＜ 0.05).Conclusion PKP can relieve pain for vertebral compression fractures in perimenopausal women in short term and long term,and PKP can also improve spinal kyphosis and prohibit the decline of bone mineral density.

Objective:To investigate the clinical manifestations, treatments and prognosis of subacute arsenic poisoning.Methods:In January 2020, a retrospective analysis was carried out on 11 patients hospitalized with subacute arsenic poisoning caused by arsenic contaminated drinking water. We observed manifestations, treatments and prognosis.Results:The main clinical presentations of subacute arsenic poisoningin were gastroenteritis in early phase, some of them had other organ damage, such as skin, blood, liver, kidney, cardiovascular and so on. The later phase was mainly peripheral nervous system damage. The treatment was mainly to chelate arsenic, protect target organs and treat toxic peripheral neuropathy. Most were significantly recoveried, but the recovery of severe toxic peripheral neuropathy was tardy.Conclusion:Acute gastroenteritis is the mainly early manifestation of subacute arsenic poisoning caused by digestive tract, and toxic peripheral neuropathy in the later phase. The prognosis is good, but the recovery of severe toxic peripheral neuropathy is tardy.

Objective To investigate the effect of human pulp stem cells(hDPSC)-derived exosomes(Exo)modified by circRNA(circRNA)signal-induced proliferation-associated protein-like 1(SIPA1L1)on the angiogenesis of human umbilical vein endothelial cells(HUVEC).Methods hDPSC was isolated and cultured from pulp tissue,the circSIPA1L1 overexpression plasmid was transfected into hDPSC,and Exo was isolated and identified.HUVEC was divided into control group,hDPSC Exo group and circSIPA1L1-hDPSC Exo group.After culture for 48 h,the vasculoformation ability was detected by Matrigel matrix gel vasculoformation test,the expres-sion levels of vascular endothelial growth factor(VEGF),vascular endothelial growth factor receptor 2(VEGFR2)and placental growth factor(PGF)were determined by qRT-PCR and Western blot.Results The Exo was success-fully isolated from the untransfected hDPSC and the hDPSC transfected with circSIPA1L1,and compared with the HDPSC-derived Exo,the relative expression of circSIPA1L1 in the hDPSC Exo transfected with circSIPA1L1 was significantly up-regulated(P＜0.05).Compared with hDPSC Exo group,the number of HUVEC tubular structures in circSIPA1L1-hDPSC Exo group was significantly increased(P＜0.05),and the mRNA and protein relative expressions of VEGF,VEGFR2 and PGF were also significantly up-regulated(P＜0.05).Conclusions Modification of hDPSC-derived Exo by circRNA SIPA1L1 can promote angiogenesis,and the mechanism may be related to up-regulation of VEGF,VEGFR2 and PGF expression levels.

Objective To explore the influence of the noviciate mode of the pregnant and lying-in woman all-the-way tracking on midwifery students' professional attitude and capability development. Methods Eight-one junior college midwifery students of grade 2013 were included. They were divided into the control group (n=42, one class) and the observation group (n=39, the other class) with the convenience sampling method. The traditional noviciate mode was used in the control group and the all-the-way tracking noviciate mode was used in the observation group. The students' performance in the two groups before and after the noviciate was compared according to the nursing student professional identify questionnaire, the clinical thinking scale and the supportive communication scale.Results After the noviciate,the professional identity, the critical thinking ability and the supportive communication ability of the students were (2.65±0.41),(3.58±0.43) and (3.87±0.18) in the observation group,respectively, and (2.39±0.43),(3.07±0.32) and (3.38±0.15) in the control group, respectively. All the scores in the observation group were significantly higher than those in the control group (t=2.66,6.49,12.83;P<0.01).Conclusions The pregnant and lying-in woman all-the-way tracking noviciate can increase midwifery students' professional identity, which is helpful for the development of the studnets'comprehensive ability.
