AIM:To study the pharmacological action of Zhikang Capsule (Herba et Radix, Paederiae scandentis, etc.) METHODS: To establish the model of anus injury in the rectal position on rabbit, anti-inflammation and analgesia effect in rats and mice were observed by carrageen and hot-plate method, and inflammatory mediator PGE_2 of rat paw edema was analysed. RESULTS: Zhikang Capsule had the obvious effect to help heal and recover the anus injury in the rectal position and it could inhibit rats’ thorax leukocytoplania and rat paw edema of Garrageenan-induced and cotton pellet-induced granuloma formation in mice. The exudation of blood capillaryies and the contents of inflammatory medium PGE_2 were lowered and improved in the pain threshold. CONCLUSION: Zhikang Capsule has the obvious effect on the healing and recovery of the anus injury in the rectal position, its anti-inflammiting effect is related to the decrease in the exudation of blood capillaries and the contents of inflammatory medium PGE_2.

Objective To study the antileukemia immune response of IL-18 gene transfected dendritic cells(DCs) of chronic myelogeous leukemia(CML).Methods DCs were transfected with IL-18 gene by liposomes in CML.The expression of IL-18 in IL-18 transfected DCs was detected.The percentages of CD80+ and CD86+ cells in IL-18 tranfected DCs were determined by FCM.The proliferation of T cell,NK and specific CTL kill activity induced by IL-18 gene transfected DCs were detected.Results The quantity of IL-18 in IL-18 tranfected DCs was(596?34.1)pg/2?106cells/48 h,while the culture medium of mock-transduced DCs and DCs did not secrete detectable levels of IL-18.The percentages of CD80+ and CD86+ cells in IL-18 tranfected DCs were higher than that in mock-transfected DCs(P

Objective To compare the efficacy of photodynamic therapy (PDT) alone or in combined with ranibizumab versus ranibizumab monotherapy (intravitreal injection,IVR) in patients with polypoidal choroidal vasculopathy (PCV).Methods 80 eyes of 72 patients with PCV were enrolled into this retrospective and comparative study according to their therapeutic plan.30 eyes of 28 patients,28 eyes of 30 patients and 22 eyes of 21 patients were divided into PDT group,ranibizumab 0.5 mg group (IVR group) or the combination group,respectively.The patients with PCV were diagnosed according to clinical symptoms,optical coherence tomography (OCT) and fluorescent indocyanine green angiography (ICGA).The baseline best-corrected visual acuity (BCVA) before treatment was more than 0.05,and there was no retinal fibrosis and scar for all patients.There was no statistical difference of age (F=0.187),gender (x2 =0.423),average BCVA (F=1.120) and central retinal thickness (CRT) (F=0.431) among three groups (P＞0.05).They had not received any treatment before.Patients received verteporfin PDT in PDT group,3 consecutive monthly IVRs starting day 1 in IVR group,and 3 IVRs after 3 days,1 month,2 months of PDT starting day 1 in combination group.Re-treatment was considered 3 months later if the follow up shown no changes in fundus photography,OCT and ICGA.The average follow-up time was 19 months.BCVA at baseline and follow-up visit at 1,3,6,12 months was measured,and the proportion of patients with ICGA-assessed complete regression of polyps at month 6 was recorded as primary outcome.The CRT was measured at baseline and 6 months as secondary outcome.Results There were significant difference of BCVA at 1,3,6 and 12 months among three groups(F=5.480,5.249,3.222,4.711;P＜0.05).The average BCVA was significantly better at 1,3,6,12 month than that at baseline(t =-6.632,-4.127,-3.904,-4.494;P＜ 0.05) in combination group,and was significantly better at 3,6,12 months than that at baseline (t=-5.636,-3.039,-3.833;P＜0.05) in IVR group.However there was no significant difference of the average BCVA in PDT group between follow-up at 1,3,6,l 2 months and baseline (t=1.973,0.102,-0.100,-0.761;P＞0.05).The proportion of patients with complete regression of polyps at 6 months was higher in PDT (76.7％) or combination group (68.2％) than IVR group (35.7％) (x2=0.003,0.025;P＜0.05).There was no significant difference of CRT among 3 groups at baseline (P=0.651).The mean CRT decreased in all 3 treatment groups over 6 months (t=5.120,3.635,5.253;P＜0.05),but there was no significant difference of CRT among 3 groups (F=1.293,P＞ 0.05).Conclusions Three therapies could effectively decrease CRT.IVR or IVR combined with PDT are both more effective than PDT therapy to improve vision of PCV patients.PDT or PDT combined with IVR was superior to IVR pnly in achieving complete regression of polyps in 6 months in PCV patients.

Objective To study the clinical features of hyperkalemic periodic paralysis (hyperKPP) and the relationship with SCN4A gene in a Chinese family Methods The clinical features of 7 patients in a Chinese family with hyperKPP were summarized All 24 exons of SCN4A gene were screened with denaturing high performance liquid chromatography (DHPLC) technology, and then sequence analysis was performed on those with abnormal elution peak Results This family showed typical clinical features of hyperKPP but without myotonia Three mutations were found in exon 13, 23 and 24 respectively Linkage analysis and direct sequencing showed the mutation in exon 24 was a synonymous mutation The mutation in exon 23 was a missense mutation, but proved to be a benign polimophism; the mutation in exon 13 was proved leading to the best known amino acid exchange Thr704Met Conclusion SCN4A gene should be related to hyperKPP, and Thr704Met be responsible for hyperKPP in this Chinese family

Objective: This study aimed to compare and analyze the functional differences between peripheral blood mono-cyte-derived dendritic cells (DCs) of Helicobacter pylori-positive and H. pylori-negative patients with gastric cancer. Methods:H. py-lori infection was detected in 84 patients with gastric cancer in our hospital from January 2011 to October 2012 by the 14C-urea breath test. DCs were generated from monocytes isolated by an adherent method from the two groups of patients and cultured in the presence of rhIL-4, rhGM-CSF, and rhTNF-α. Furthermore, the expression of surface marker molecules was determined by fluorescence-activat-ed cell sorting analysis. The cytotoxicity of DCs pulsed T cells against gastric carcinoma cell was assessed by the lactate dehydroge-nase-releasing assay. The secretion of IL-12 and IFN-γin the supernatant was determined by enzyme-linked immunosorbent assay. Re-sults:No difference was observed in the morphological change of the maturation process. The mean expression of CD1a, CD80, CD83, CD86, and HLA-DR molecules in DCs of H. pylori-infected patients was higher than that in DCs of H. pylori-negative group, and the differences were statistically significant except for CD1a and HLA-DR. The cytotoxicity activities, IL-12 release, and IFN-γrelease in the H. pylori-positive group were significantly higher than those in the H. pylori-negative group (P<0.05). Conclusion:H. pylori infec-tion has no effect on the morphological change of the maturation process of monocyte-derived DCs. These data clearly demonstrate that monocyte-derived DCs of H. pylori-infected patients with gastric cancer can induce stronger maturation and activation than those of H. pylori-negative patients.

Objective:To study the effect of mindfulness-based training intervention on clinical efficacy in patients with nitrous oxide(laughing gas) addiction.Methods:From June 2019 to June 2020, sixty-six patients with nitrous oxide addiction in Beijing Gaoxin Hospital were selected and randomly divided into experimental group( n=33) and control group( n=33). The control group received Taijiquan training and physical training, while the experimental group added mindfulness-based training intervention on the basis of Taijiquan training and physical training.Symptom checklist 90 (SCL-90) scores and visual analog scales (VAS) craving scores were compared between the two groups at admission and 8 weeks after treatment.SPSS 22.0 software was used for statistical analysis.Independent sample t test and paired sample t test were used to compare the differences between groups and within groups. Results:(1)Before treatment, there were no significant differences in subscale scores of SCL-90 between the two groups except for depression factor((2.45±0.86), (2.03±0.46), t=2.474, P<0.05). After treatment, the subscale scores of somatization((1.38±0.35), (1.68±0.34), t=-3.656, P<0.05), phobic anxiety((1.49±0.37), (1.81±0.30), t=-3.993, P<0.05), paranoid ideation((1.50±0.47), (1.88±0.31), t=-3.898, P<0.05) and psychotism((1.34±0.54), (1.55±0.27), t=-3.094, P<0.05) of SCL-90 in the experimental group were significantly lower than those in the control group.(2)Before treatment, there was no significant difference in VAS craving score between the two groups( t=0.857, P=0.395). After treatment, the score of VAS in the experimental group was significantly lower than that in the control group( t=27.427, P<0.05). Conclusion:Mindfulness training intervention can effectively improve the clinical symptoms of patients with nitrous oxide addiction, which is worthy of clinical application.

Objective To investigate the value of evaluation of pelvic floor ultrasound in the transvaginal modified patch repair and sacrospinous ligament fixation in uterine prolapse patients. Methods Thirty-two patients with uterine prolapse were included in the retrospective study from March 2016 to January 2017 in Hangzhou maternity and child health care hospital. All patients were detected by pelvic floor ultrasound before operation and cured by vaginal patch bilateral sacral spine ligament fixation treatment after. Of them, 8 cases were complicated with cystocele and 3 cases with anorectal prolapse, and all the complications were treated at the same time. The observations of the change of position, shape and activity of the implant by transvaginal at rest, on maxium Valsalva and contraction, and the transperineal pelvic ultrasound were performed to evaluate the change of pelvic floor function and compare the distance from the lowest point of the bladder, uterus and the rectal ampulla to reference line (the horizontal line at the lower margin of the pubic bone), area of levator hiatus and the thickness of the puborectalis muscle before and after operation. Results The patches were observed 2D and 3D postoperatively by pelvic ultrasound. The U-shaped hyperecho could be clearly shown around the cervix and activity of patches were clearly shown. The observation of 32 cases of patients with pelvic viscera situation by the transperineal 2D and 4D pelvic ultrasound: the distance from the lowest point of the bladder, uterus and the rectal ampulla to reference line and the thickness of the puborectalis muscle enlarged after operation (0.65±1.85 vs 0.15±1.85, 2.80±1.10 vs -1.00±1.50, 0.60±1.90 vs-0.55±1.55,0.51±0.24 vs 0.37±0.19)onmaxium valsalva,the area of levator hiatus decreased after operation (20.15±7.20 vs 29.00±9.50).The differences were both statistically significant (all P < 0.05). Uterine prolapse were not found after operation. In the 8 cases with cystocele, 5 cases were cured and 3 cases were improved. And all the 3 cases of patients with anorectal prolapse were all cured. Conclusion Combined application of transvaginal and transperineal pelvic ultrasound can clearly show the suspension of the patch after the treatment of modified patch repair and Sacrospinous ligament fixation, which provide valuable imaging information in the evaluation of preoperative pelvic functionand postoperative therapeutic effect.
