BACKGROUND: Sliding cupping has been used for treating cervical spondylosis, with the effects of dredging the meridian system, activating qi and removing blood stasis.OBJECTIVE: To probe into symptomatic improvement of cervical spondylosis with sliding cupping and the relationship between curative effect and course of disease as well as age.DESIGN: Self controlled observation.SETTING: Department of Physiotherapy, General Hospital of Air Force of Chinese PLA.PARTICIPANTS: Totally 100 out-patients with cervical spondylosis receiving treatment in the Department of Physiotherapy, General Hospital of Air Force of Chinese PLA were involved from December 2000 to December 2003. Among them, 39 cases were male and 61 cases were female; 9 cases were under 30 years old, 38 cases were 31 to 40 years old, 42 cases were 41 to 50 years old and 11 cases were above 50 years old. There were 36 cases with less-than-one-year course of disease, 49 with 1 to 5-year course and 15 with more-than-5-year course. Fifty-one cases were cervical type; 25 cases vertebral artery type; 24 cases nerve root type. X-ray examination revealed that there were 69 cases whose cervical vertebral physiological curvature became straight or reverse, or with certain degree of degenerative change. Vertebroarterial blood supply insufficiency was detected in 23 cases by rheoencephalogram.INTERVENTIONS: The patients were asked to be in prone sitting position,their nape and shoulder were fully exposed, and the negative pressure cupping was applied to patient' s nape and shoulder until petechiae appeared on the skin. The treatment was given once or twice a week. After one-month treatment, the curative effect was calculated according to subjective symptoms, signs, and the results of X-ray and rheoencephalogram examination before and after treatment. Symptom disappearance: pain was 0 grade; the cervical vertebral physiological curvature restored by 10°- 15° and rheoencephalogram showed that the contraction peak velocity of the vertebroarterial blood supply became normal. Marked improvement: the pain reduced by more than 2 grade, the cervical vertebral physiological curvature restored by 6°9° and rheoencephalogram showed that the vertebroarterial blood supply restored to 80% of the normal range. Improvement: the pain reduced by 1 grade, the cervical vertebral physiological curvature restored by 3°- 5° and rheoencephalogram showed that the vertebroarterial blood supply restored to 40% - 80% of the normal range. Inefficacy: the pain did not reduce, the cervical vertebral physiological curvature restored by less than 3° and rheoencephalogram showed that the vertebroarterial blood supply became less than 40%.RESULTS: According to the intention-to-treat analysis, 100 patients entered the result analysis. For symptom disappearance, marked improvement,improvement, inefficacy there were 27, 17, 5 and 2 cases respectively in cervical type; 8, 10,4 and 3 cases respectively in the vertebral artery type;4,9,7 and 4 cases respectively in the nerve root type. There were 19, 12, 3 and 2 cases respectively with less-than-one-year course of disease; 18, 19, 7 and 5 cases respectively with 1 to 5-year course; 2, 5, 6 and 2 cases respectively with more-than-5-year course. And there were 5, 3 and 1 cases respectively with age ＜ 30 years; 18, 13, 4 and 3 cases respectively with age of 31 to 40 years; 15, 18, 5 and 4 cases respectively with age of 41 to 50years; 1, 2, 6 and 2 cases respectively with age ＞ 50 years.CONCLUSION: The effect of sliding cupping was good for patients with cervical spondylosis of vertical type, next of vertebroarterial type and bad of nerve root type. The shorter the course of disease is, the younger the patient is, and the better the curative effect is.

With the progress of science technology,the 3D technology has raised comprehensive attention for its application value in medical field,especially in the orthopedic field.It has been mainly used before complicated orthopedic surgeries,and several studies have focused on 3D duplicated materials used in the treatment of bone defect.However,there are seldom studies about the 3 D technology used during surgeries,such as whether it is possible to 3D print internal fixation materials of bone fracture (the materials have biodegradability and excellent biomechanical characteristics),which can not only promote the healing of fracture,but also reduce the pain of second surgery for the patient.This paper reviews and summarizes the exploration of foreign and domestic scholars about the application value of 3 D printing technology used in complicated bone fracture,and proposes a forecast to the developing trend of the technology used in future orthopedic surgeries.

Objective To investigate epidemiological pattern of dementia and major subtypes,we conducted a prevalence survey in Beijing,China. Methods A door to door three phase procedure was used to ascertain dementia A Chinese version of Mini Mental State Examination (CMMSE) was administered to all participates in 1997 Then,those who failed the screening tests and those of the normal,but having a suspected history of cognitive impairment were interviewed by neurologists or psychiatrists for a diagnostic assessment of dementia,Alzheimer′s dementia (AD) and vascular dementia (VaD) using the DSM IV,NINCDS ADRDA,and NINCDS AIREN criteria Validity of the diagnostic approach was confirmed by a follow up study in 1998 Participants a total of 5 913 residents aged 55 years and over from 12 urban and 17 rural communities was drawn through a stratified multiple stage cluster sampling 5 743 (96 1%) were interviewed. Results A total of 262 cases of mild to severe dementia were identified The crude and age standardized prevalence in individuals aged 55 years and over were 4 6% and 4 2% for dementia (all causes),2 2% and 2 0% for AD,and 1 6% and 1 5% for VaD,respectively The prevalence of AD increased doubling every 5 years with age,but the prevalence of VaD increased low and slow The age standardized prevalence of AD was 1 7% in men lower than 2 1% in women,but the prevalence of VaD was 1 7% in men higher than 1 3% in women for individuals aged 55 years and over The difference in age standardized prevalence of AD between urban and rural communities was not significant that was 1 8% versus 2 2% in individuals aged 55 years and over; but the corresponding figures of VaD in rural (2 2%) was significantly higher than that in urban (1 0%) Either for AD or for VaD,there were no significant relationships between age standardized prevalence rates and educational levels Conclusion Our overall prevalence of dementia and its subtypes is considerably higher than previously reported estimates from China and similar to those reported in whites The epidemiological and clinical patterns for AD differed from VaD,but it was similar to those reported in whites It suggests that there are no substantial differences across cultures for AD

The test samples were clustered into three classes. CONCLUSION: The established method is simple, reliable and accurate. It can be used to determine the saccharide components in Qingkailing injection, and provide theoretical basis for its quality control.

Objective To assess the efficacy of ropivacaine in combination with different doses of sufentanil for epidural anesthesia in patients undergoing hysterectomy. Methods Eighty ASA Ⅰ or Ⅱ patients aged 30-55 yrs weighing 40-70 kg undergoing elective hysterectomy were randomly divided into 4 groups ( n = 20 each) : ropivacaine group (R) and 3 ropivacaine-sufentanil groups (R-S1-3). The patients were unpremedicated. ECG, BP, HR and SpO2 were monitored during ansthesia. Each patient received an epidural catheter placed at L2,3 interspace. After correct placement of epidural catheter was confirmed 0.75% ropivacaine 13 ml and normal saline (NS) 2 ml were given through epidural catheter in group R whereas in the 3 R-S groups 0.75% ropivacaine 13 ml and sufentanil 10 (R-S1), 20 (R-S2) or 30 (R-S3) ?g in NS 2 ml were injected into epidural space. BP, HR and SpO2 were recorded every 3 min. The onset time, upper spread and duration of sensory block; onset and duration of motor block (Bromage scale); degree of abdominal muscle relaxation; level of sedation (OAA/S scale); anesthetic efficacy and side-effects were recorded. The dose-response curve constructed by probit regression analysis was established to calculate ED50 and ED95. Results The onset time, the time needed to reach the highest sensory level were significantly shorter and the duration of sensory block was significantly longer in the 3 R-S groups than in R group ( P

AIM: To investigate the effect and mechanism of 5-aminosalicylic acid (5-ASA) in topical treatment on trinitrobenzene sulfonic acid (TNBS)-induced colitis in rats. METHODS: Colitis was induced by intracolonic administration of TNBS and was treated with 5-ASA at the dose of 100 mg?kg -1 for 2 weeks. Normal control group was administrated with normal saline and TNBS control group was treated with TNBS, not with 5-ASA. Macroscopic damage, histological changes and myeloperoxidase (MPO) activity were evaluated. Superoxide dismutase (SOD) activity and malondialdehyde (MDA) level in colonic mucosa were detected by kits. The expression of interleukin-1? (IL-1?) and tumor necrosis factor-? (TNF-?) mRNAs in colonic mucosa was determined by a reverse transcription and polymerase chain reaction method. RESULTS: Compared with TNBS control group, the macroscopic and histological changes and MPO activity in 5-ASA treated groups were improved. SOD activity was increased and the level of MDA in colonic mucosa was reduced significantly. The expression of IL-1? and TNF-? mRNAs in colonic mucosa was also decreased significantly. CONCLUSION: 5-ASA enema can significantly ameliorate TNBS-induced colitis in rats via antioxidant mechanism and attenuation of proinflammatory cytokine expression.

Objective:To retrospectively analyze the clinical data of 73 children with non-Hodgkin′s lymphoma to determine its clinical features, pathological types and relationship with efficacy.Methods:In Shanghai Children′s Hospital from October 2014 to October 2018, 73 children with newly diagnosed non-Hodgkin′s lymphoma were enrolled for a retrospective study, with 52 males and 21 females, aged between 2 and 13 years old, so as to comprehensively assess cumulative organs, pathological diagnosis, stage of disease, surgery and efficacy.Results:Among the 73 children with non-Hodgkin′s lymphoma, 66 cases had a clear pathological diagnosis, including 38 cases of surgical pathology and 20 cases of biopsy pathology.All of them were confirmed by immunohistochemisty, and 8 cases were determined by flow cytometry.Meanwhile, 6 cases of the rest 7 cases obtained approximate pathological classification.Only 1 case was unknown.Among the 66 cases, Burkitt lymphoma was the most common in 31 cases, followed by 14 cases of T-lymphocyte type, 7 cases of enlarged lymphoma, 6 cases of B-lymphocyte type, 5 cases of diffuse large B lymphoma, 1 case of extranodal natural killer/T cell lymphoma-nasal type, 1 case of blastic plasmacytoid dendritic cell neoplasm, and 1 case of panniculitis-like T lymphoma.The initial site or cumulative organ involved multiple organs, with most common in neck(20 cases), abdominal cavity(15 cases), and mediastinum(6 cases). In view of outcomes and efficacy, the complete remission rates of stage Ⅱ, Ⅲ, and Ⅳ in clinical were 100.0%, 85.1%, and 72.2%, respectively.The event-free survival rates in stage Ⅲ and Ⅳ were lower than those in stage Ⅱ(80.9% vs. 66.7% vs. 100.0%). From the perspective of the main pathological types grouping, the results revealed that lymphoblastic lymphoma had a lower event-free survival rate than Burkitt′s lymphoma (73.7% vs.90.3%), while there was no statistical significance(all P>0.05). Conclusions:Non-Hodgkin′s lymphoma in children is more common in men, and less common in infants and young children.Pathological type is simpler than adults, Burkitt lymphoma is the most common type, and clinical stage and pathological type may be related to prognosis.

Objective To study the effect of intestinal trefoil factor(ITF) on nuclear factor-?B(NF-?B) in neonatal rats intestinal tissues with necrotizing enterocolitis(NEC),and to discuss whether ITF had protective function in NEC,and its role in the mechanism of NEC.Methods Fifty neonatal rats were randomly divided into 5 groups:group A as control group,group B as control plus ITF 0.2 mg group,group C as NEC group,group D as NEC plus normal saline(NS),group E as NEC plus ITF 0.2 mg.NEC models of neonatal rats were established.On the 4th day,all subjects were put to death.The intestinal tissue located at the boundary of ileum and cecum were obtained to observe histological changes and NF-?B level.Results The density of NF-?B(p65) increased significantly in group C and D compared with those in group A,B and E(Pa

Objective:To investigate the effectiveness and safety of manual acupuncture for memory loss and sleep quality in chronic insomniacs.Methods:A total of 60 eligible participants were enrolled and randomized into either a treatment group or a control group,with 30 cases in each group.The treatment group was intervened by manual acupuncture whereas the control group was given sham acupuncture.In the two groups,the interventions were offered once every other day and three times a week,for 8 weeks in total.Before and after the treatment,Pittsburgh sleep quality index (PSQI) and eventrelated potentials (ERPs) were used to assess the patients' sleep quality and memory,respectively.Meanwhile,adverse events were monitored and recorded.Results:After 8-week treatment,both the treatment group and the control group showed a significant decrease in the PSQI global score (P＜0.001,P＜0.01),and the decrease in the treatment group was more significant than that in the control group (P＜0.001).The intra-group comparisons of ERPs indicated that,the latencies of N1 and P3 were shortened and the amplitudes of N1 and P3 were increased in the treatment group after the intervention,and the differences were statistically significant (P＜0.05,P＜0.001);in the control group,there were no significant changes in the latency and amplitude after the treatment (P＞0.05).The between-group comparisons of ERPs showed that the treatment group was more effective than the control group in shortening the latency of P3 (P＜0.01).Conclusion:Acupuncture can be a safe and effective treatment option for chronic insomnia coupled with memory impairment.

The mainly antigenic sites for the adenovirus neutraliation are present on Loop1 and Loop2 of hexon.Majority research were focus in the human adenovirus.Little was known on infectious canine hepatitis virus (ICHV), which was also called canine adenovirus typeⅠ.Here,ICHV (the isolated strain) DNA was isolated and purified from the cultured MDCK cells.The Loop1 and Loop2 fragments were amplified by polymerase chain reaction(PCR) method,and then was connected by ligase T4.The target fragment was then connected with vector pET28a.The nucleotide sequence ecoding Loop1 and Loop2 was determined.The nucleotide sequence identity of Loop1 region between the isolated strain and CLL, RI261 and Toronto A26/61 strains is 100%, 100% and 83.8%, and the nucleotide sequence identity of Loop2 region between the isolated strain and CLL, RI261 and Toronto A26/61 strains is 88.1% , 88.1% and 99.3%, and amino acid identity is 93.6%, 93.6% and 98.6%.The recombinant Loop protein was expressed in E.coli and was approximately 36kDa in size,and then was purified. Then BALB/c mice were injected subcutaneously in the back and armpit with the recombinant Loop protein.The anti-ICHV antibody titers of immunized serum was tested by indirect ELISA and the titers were up to 1:320.Western blot demonstrated that immunized sera could specifically combine with ICHV. The research laid a foundation for creating new genetic engineering products of infectious canine hepatitis virus.
