Objective:To observe the effect of complex reinforcing [Shao Shan Huo (Mountain-burning Fire)] and reducing [Tou Tian Liang (Heaven-penetrating Cooling)] manipulations on motion and balance of the lower limbs in patients with subacute combined degeneration of the spinal cord (SCD). Methods:A total of 100 SCD cases were randomly allocated into an observation group and a control group by their visit sequence, 50 cases in each group. On the basis of Western medical treatment, cases in the observation group were also treated with acupuncture therapy plus complex reinforcing-reducing manipulation; whereas cases in the control group were only treated with the same Western medical treatment as those in the observation group. Before and 2 months after treatment, kinematic parameters including muscle force, muscle tone and range of motion of the hip and knee joints were measured. In addition, balancing parameters including the path length of center of pressure (COP), peripheral area, COP path length per unit area and rectangular area were also measured before and after treatment. Results:After treatment, there were statistical intra-group differences in COP path length, peripheral area, COP path length per unit area, left-right offset, rectangular area, coefficient of stability and coefficient of weight distribution (P<0.01). There were statistical inter-group differences in muscle force, muscle tone and range of motion of hip and knee joints (P<0.01). The total effective rate was 83.3% in the observation group, versus 60.0% in the control group, showing a statistical difference (P<0.05). Conclusion:Complex reinforcing-reducing manipulations can improve the lower limb motion and balance in SCD patients.

Objective To evaluate the safety and efficacy of treating bifurcation lessions with jailed-balloon technique in simple strategy. Methods Ninety patients with bifurcation lessions (Duke D or F type) who received the side branch protection technique with simple strategy were involved in a single center retrospective analysis. Patients were randomly divided into jailed-balloon protection group (n=48) and jailed guidewire group (n=42). The process operating, procedural success of percutaneous coronary intervention (PCI) and percutaneous transluminal coronary angioplasty (PTCA), complications and the results of follow-up were investigated. Results The clinical baseline date and the bifurcation lesions were not significant different between jailed-balloon group and jailed guidewire group (P>0.05). The procedural success rate of PCI was 100%in jailed-balloon group and 97.6%in jailed guidewire group, no significance difference user between two groups (P>0.05). The perioperative complications (the rate of no reflow) was lower in jailed-balloon group than those of jailed guidewire group (1.0%vs. 19.0%, P<0.05). The procedural success rate of PTCA were lower in jailed-balloon group than that of jailed guidewire group (4.2%vs. 23.8%, P<0.01). The total operation time [(56.40±11.71) s vs. (72.60±10.62) s],exposing time [(9.86±1.82) s vs.(12.24±2.32)s] or amount of used contrast agent [(90.54±15.26) mL vs. (118.16±18.64) mL] were significantly lower in jailed-balloon group compared with those of jailed guidewire group (P<0.05). At the 12-month follow-up, the MACE was lower in the jailed-balloon group than that of jailed guidewire group (16.7%vs. 38.1%, P<0.05). The restenotic rate (2.1%vs. 4.8%, P>0.05) and the maximum restenotic level (19.24%vs. 21.46%,P>0.05) in the main branch were not significant different between jailed-balloon group and jailed guidewire group. But the maximum restenotic level in the opening of side branch was lower in jailed-balloon group than that of jailed guidewire group (51.2% vs. 72.46%, P < 0.01). Conclusion The jailed-balloon technique reduces the operation complications, exposure time and amount of contrast agent, and also saves surgical consumables. The procedure of branch with simple strategy is safe and effective in treatment of bifurcation lesions.

BACKGROUND:The effect of advanced glycation end products (AGEs) on bone resorption is controversial. Our previous study has shown that bone resorption is significantly inhibited when AGEs present with pre-osteoclast cells RAW 264.7, while the effect of AGEs on osteoclastic acidification remains unknown. OBJECTIVE:To investigate the effect of AGEs on osteoclastic acidification and the underlying mechanism. METHODS:RAW 264.7 cells were induced by RANKL (15μg/L;normal group) to generate osteoclasts, and AGEs (50-400 mg/L;experimental group) or bovine serum albumin (100 mg/L;control group) were added at the beginning of the induction. The effect of AGEs on bone resorption was evaIuated by anaIyzing the area of bone resorption on the Osteo Assay Surface plates, and the effect of AGEs on osteoclastic acidification was evaluated by acridine orange staining. Furthermore, the expression levels of V-ATPase a3 and CIC-7 were detected to investigate the underlying mechanism. RESULTS AND CONCLUSION:The bone resorption area in the AGEs group was significantly decreased compared with the normal group (P<0.05). Acridine orange staining reveaIed that the red fluorescence (620 nm) intensity in the AGEs group was significantly decreased compared with the normal group (P<0.05), and this inhibitory effect became obvious with the increase of AGEs concentration. Immunocytochemistry, western blot assay and PCR findings showed that the expression levels of V-ATPase a3 and CIC-7 in the AGEs group were decreased significantly compared with the normal group (P<0.05). To conclude, AGEs exert inhibitory effect on osteoclastic acidification, probably by inhibiting the expression of V-ATPase a3 and CIC-7.

Objective To study the influence of residual methylene blue after plasma viral inactivation on the human immune cell function by using the peripheral blood mononuclear cell(PBMC) .Methods PBMC were isolated by adopting the Ficoll‐Hypaque density gradient centrifugation method and co‐cultured for 72 h in presence of specific T cell stimulating factors(Anti‐CD3/28 and Anti‐CD28) ,with or without different concentration of methylene blue .The culture supernatant was collected and detected the cyto‐kines secretion situation by ELISA .After 66 h culture ,CCK‐8 dye was added and continueously cultured for 4-6 h ,the prolifera‐tion was determined at A450 .Results The high‐concentration doses of methylene blue (1 .25 ,2 .5 ,5 μmol/L groups) had signifi‐cantly inhibiting effect on the proliferation of PBMC stimulated by Anti‐CD3/28(P< 0 .01) ,its OD value was decreased from 0 .897 ± 0 .385 to 0 .632 ± 0 .334 ,0 .524 ± 0 .254 and 0 .445 ± 0 .287 respectively ,showing certain dose dependent effect .The high concentrations of methylene blue (1 .25 ,2 .5 ,5 μmol/L groups) could down‐regulate interleukin(IL)‐17a ,IL‐10 and interferon (IFN)‐γ secreted by anti‐CD28 induced PBMC ,moreover showing a dose dependent effect .1 .25 ,2 .5 ,5 μmol/L methylene blue af‐fected the IL‐17a level secreted by PBMC from (406 ± 57)pg/mL descending to (276 ± 38) ,(192 ± 31) ,(134 ± 24)pg/mL respec‐tively ;affected PBMC to secrete IL‐10 ,its level was reduced from (184 ± 15) pg/mL to (132 ± 13) ,(110 ± 12) ,(42 ± 8)pg/mL ;af‐fected PBMC to secrete IFN‐γ,its level was deduced from (4 512 ± 187)pg/mL to (2 876 ± 143) ,(2 234 ± 153) ,(1 988 ± 112)pg/mL respectively .Conclusion High concentrations of methylene blue (≥1 .25 μmol/L ) has the significant inhibiting effect on the proliferation and cytokine secretion functions of PBMC .In other words ,the residual methylene blue concentration in viral inactiva‐tion plasma (≤0 .33 μmol/L) has no obvious effect on the immune function of PBMC ,but whether this concentration of methylene blue having the effect on human pure T cell immune function needs to be further evaluated and studied .

The most common metastatic site of prostate cancer is the bone, followed by the lung, bladder, liver, and adrenal gland. We report on a rare case of pancreatic metastasis from prostate cancer. A 52-year-old patient was admitted to the hospital with epigastric pain for 20 days. PET-CT showed malignant lesions in the prostate and pancreas, and prostate and pancreas puncture biopsies were performed, respectively. The patient was diagnosed as prostate cancer with pancreatic metastasis according to the pathological findings. After undergoing androgen deprivation therapy and docetaxel chemotherapy for 6 cycles, reexamination revealed that the pancreatic metastases had disappeared.

Objective Using the indicator system to objectively evaluate the content and effectiveness of the new culture construction in typical public hospitals,so as to identify problems and put forward suggestions for improve-ment.Methods Applying the new culture index system for the high-quality development of public hospitals con-structed by the research group,it quantitatively evaluated the practice of new culture construction in a tertiary hospi-tal in Shanghai.Results It found that the main body of the hospital's new culture construction scored 98.9 points.The 2 dimensions of hospital culture system construction and carrying out effectiveness(additional indicators)were all full scores.In addition,the dimension of caring for medical staff was 24.8 points,the dimension of strengthening pa-tient demand orientation was 24.6 points,and the dimension of distinctive hospital culture was 24.5 points.There are still deficiencies in the dimensions of the post-diagnosis experience of patients,the cultivation of health habits of staff,and the transformation of scientific research.Conclusion The hospital has taken advantage of the top-level de-sign of cultural construction under the leadership of the Party Committee and has improved the relevant systems.The hospital also focuses on several special cultural projects such as cultural heritage,employee care,optimization of ac-cess to medical care,and popularisation of scientific brands.It propose to promote the high-quality development of the hospital's new culture by carrying out Internet medical care,organizing special staff activities,strengthening the guidance of scientific research policies,and increasing the financial support for projects.

Objective It investigates medical staff's perception and experience sense of hospital culture,and analy-ses its influencing factors.This can further play the role of hospital culture construction on medical staff's motiva-tion,and improve medical staff's work motivation to provide reference basis.Methods The Medical Staff's Percep-tion and Experience of Hospital Culture scale developed by the research team was used to conduct a questionnaire survey with on medical staff in the sample hospital.Descriptive analysis,single factor analysis and multiple linear re-gression analysis were used to study the medical staff's perception and experience of hospital culture and its influ-encing factors.Results A total of 629 valid questionnaires were collected.The overall score rate of medical staff's per-ception and experience of hospital culture was over 90%.Among them,the highest scoring rate of the mission bearing subscale,and the dimension with higher scores was vision and goals.However,the experience of work environ-ment,promotion system and research environment is relatively low.The results of the one-way test showed that the differences in the scores of hospital culture perception and experience among medical staff with different educa-tion levels,titles and job positions were statistically significant(P＜0.05).Conclusion Medical staff generally support the construction of hospital culture.It is suggested that the hospital culture development strategy should be formulated from the perspective of the staff and according to their goals,problems and needs.It is also recommended to con-tinuously improve the medical staff's perception and experience of the hospital culture according to their needs,so as to play a positive role in the high-quality development of the hospital by culture construction.
