Objective To explore the effect of acupuncture on trunk control ability and balance function in patients with spinal cord injury above lumbar. Methods 40 patients with spinal cord injury were randomly divided into observation group and control group with 20 cases in each group. The control group received limb joint training method, the observation group received acupuncture in addition. Fugl-Meyer Assessment and Flex Comp Infiniti EMG system were used to evaluate the balance function and trunk muscle strength before and 8 weeks after treatment. Results After treatment, the balance function and trunk control ability improved in both groups (P<0.01), and were better in the observation group than in the control group (P<0.05). Conclusion Limb linkage combined with acupuncture can further improve the balance function and trunk control ability in patients with spinal cord injury above lumbar.

Objective To evalute the effect of Ilizarov technique in the treatment of hypertrophic nonunion.Methods Form June 2008 to December 2010,12 patients with hypertrophic nonunion were treated with Ilizarov technique,including 10 males and 2 females with an average age of 46.5 years.The pathology sites of nonunion were kept as closed as possible without any bone graft during operation.As to patients who had ever been treated with plate or intramedullary nail,the hardware should be removed by minimal invasive approach.These procedures aimed to keep the vascularity of nonunion site intact.Ilizarov apparatus were preoperatively constructed.Distal segment and proximal segment of nonunion were mounted respectively with two external circle using the smooth wires and half pins.The two-circle stabilizing one segment was nominated with transosseous modules.Distal module and proximal one was connected with a pair of axial hinges.The pathology sites were gradually distracted from the seventh day postoperatively,0.25 mm/d.Accompanying with deformity correction,limb length discrepancy (LLD) also were restored simultaneously.Then,all the screws and nuts in the apparatus should be tightened,which was favourable to the callus consolidation.Results All 12 cases of nonunion healed without any bone graft.The fixator wearing time lasted 6-12 months,with an average of 8 months.Correction of deformity and LLD were achieved.The average lengthening was 3.0 cm (range,2.0-5.5 cm),the average correction angle was 23° (range,10°-30°).After 6-18 months follow-up,all the patients restored satisfactory function.Conclusion Hypertrophic nonunion can be treated successfully with Ilizarov technique.The key of successful callus distraction is strictly identifying the indications.

Objective To improve the differential diagnosis between autoimmune pancreatitis (AIP) and pancreatic cancer (PC) by a contrast analysis of imageological features.Methods Thirty-six patients who had postoperative pathological with Asian AIP standards and 95 patients who had postoperative pathological consistent with PC.The imageological results of these AIP and PC patients were analyzed.Results AIP was significantly less than PC in the enhanced CT of a mass or enlargement of the pancreatic head,enlargement of the lymph nodes around the pancreas,dilation and interrupt in pancreatic and bile duct,peripheral vascular and organ involvement (11/27 vs.28/40,2/27 vs.17/40,13/27 vs.32/40,1/27 vs.10/40,8/27 vs.26/40,2/27 vs.15/40,0/27 vs.15/40,0/27 vs.10/40,P ＜ 0.05).AIP was significantly more than PC in the enhanced CT of a diffusely enlarged pancreas,calcification or pancreatic calculus,capsule-like rim or the vague peripancreatic fat interval (4/27 vs.0/40,7/27 vs.0/40,10/27 vs.6/40,P ＜ 0.05).AIP was significantly less than PC in the three-dimensional ultrasonography of dilation diameter of pancreatic duct and dilation of common bile duct [(0.421 ± 0.270) cm vs.(0.594 ± 0.270) cm,1/18 vs.16/26,P＜ 0.05].AIP was significantly less than PC in the magnetic resonance cholangiopancreatography of dilation of common bile duct and interrupt in pancreatic duct (7/13 vs.16/18,1/13 vs.10/18,P ＜ 0.05).Conclusion AIP as a unique type of chronic pancreatitis can be distinguished from PC on distinctive imageological features

Objective To evaluate the value of medical treatment in the management of SAP.Methods From January 2000 to December 2011,a total of 1064 cases out of 931 SAP patients were admitted and retrospectively analyzed.The etiologies,severity score,complication rates,therapies,effectiveness and costs of those SAP cases were summarized.Results There were 559 males and 372 females with a mean age of (51 ± 15)years old.The main cause was biliary tract disease (58.3％),followed by fat-rich diet (31.2％),hyperlipidemia (13.6％) and alcohol (7.1％).At the time of admission,95.5％ of SAP patients presented with level D disease according to Balthazar CT severity index,26.0％ had a Ranson score ≥3 and 30.1％ had an APACHE Ⅱ score ≥ 8.There were 42.7％ cases complicated with systemic inflammatory response syndrome (SIRS).Acute lung injury and acute respiratory distress syndrome (ARDS),acute kidney injury,shock or heart failure,acute liver dysfunction,and diffuse intravascular clotting (DIC)occurred in 24.0％,8.1％,5.4％,3.2％,and 1％ of all patients,respectively.Other complications of SAP included abdominal cavity bleeding (n =17),pseudocyst bleeding (n =9),pancreatic abscess (n =78) and gastrointestinal fistula (n =33).Totally 25 (2.3％) patients died in hospital and 36 (3.4％) patients were discharged against advice,with an overall treatment success rate of 94.3％.The mean hospital stay was (23.7 ± 19.2) d,and the average cost was 52.3 thousands of RMB.Conclusions A comprehensive treatment pathway relying on medical treatment,focusing on organ function support and assisted by miniinvasive intervention may improve the treatment success rate of SAP,which is worth of further application.

OBJECTIVETo systematically evaluate the values of 4 serum markers in the diagnosis of rheumatoid arthritis (RA).

METHODSSerum samples were obtained from 278 RA patients and 510 control subjects and the levels of rheumatoid factor (RF), anticyclic citrullinated peptide antibody (CCP), antikeratin antibody (AKA), and glucose-6-phosphate isomerase (GPI) were detected using immune turbidimetry, ELISA, indirect immunofluorescence, and ELISA, respectively. The values of these 4 serum markers and their combinations in RA diagnosis were systemically assessed.

RESULTSIn RA diagnosis using one serum marker, two markers, and three or four markers, RF, RF+CCP, RF+CCP+GPI, respectively, had the highest sensitivity; CCP, CCP+AKA, and RF+CCP+AKA+GPI, respectively, had the highest specificity; CCP, CCP+GPI, and RF+CCP+AKA+GPI, respectively, had the highest positive predictive value; GPI, RF+CCP, and RF+CCP+GPI, respectively, had the highest negative predictive value; CCP, CCP+GPI, and RF+CCP+AKA+GPI, respectively, had the highest positive likely ratio; GPI, RF+CCP, and RF+CCP+GPI, respectively, had the lowest negative likely ratio.

CONCLUSIONCCP, RF+CCP, and RF+CCP+GPI are the most ideal for RA diagnosis using one, two, and three or more markers, respectively. CCP is the essential marker for RA diagnosis, and a combined detection of the serum makers can significantly improve the diagnostic accuracy.

Objective To discuss the feasibility,the advantages and disadvantages,the clinical efficacy and the indications of minimally invasive transforaminal endoscopic debridement combined with allograft and posterial percutaneous internal fixation for thoracolumbar spinal tuberculosis.Methods All of 22 patients with thoracolumbar tuberculosis treated in our department from January 2012 to December 2013 were retrospectively reviewed.There are 11 male and female cases separately,with an average age of 54.1 ±10.2 years and with an average disease duration of 5.3 ± 1.9 months.Endoscopic lesion removal and allograft bone grafting combined with posterial percutaneous immobilization were performed on all these cases.The data of these patients were complete,and all patients had been followed up for more than 36 months.The clinical and radiographic results were recorded and analyzed.Results In this group,22 patients were followed-up for 41.9±2.5 months(36-48 months).The spinal kyphosis was not improved 3 months after surgery (t=0.3546,P=0.7029),but the amount of blood loss (30.5±7.9 ml) was less in the operation,the amount of postoperative analgesics(0.3±0.1 g) was low and the bed time(1.5±0.3 days) was short.No recurrence and no internal fixation failure was found after long term follow-up.Good clinical outcomes were achieved with the fusion rate reached above grade 2 in all patients(95.5％) except one.The neuralgia was relieved,and the spinal cord injury was recovered to ASIA E.The VAS score and SF-36 score which were recorded 1 month and 3 months after operative were all improved significantly compared with those before operation,and patients' life quality in the early period after operation was excellent.The incidence of complications was low(9.0％),and the patients were satisfied with the treatment process.Conclusion It may be a potential way to treat spinal tuberculosis with minimally invasive transforaminal endoscopic debridement combined with allograft and percutaneous internal fixation,which could be a powerful supplement to other therapeutic measures,and is worthy of further research and development.

Objective:To investigate the relationship between antibacterial treatment scheme and prognosis, and to analyze the mortality risk factors of bloodstream infection with carbapenem-resistant Klebsiella pneumoniae(CRKP).Methods:A retrospective case-control study was conducted. The CRKP isolated from clinical venous blood samples in the First Medical Center, Chinese PLA General Hospital between January 1, 2013 and December 31, 2018(not included from January 1, 2016 to December 31, 2017) was collected. According to relevant standards, a total of 50 patients with bloodstream infection with CRKP were included. The patients were divided into death (19 cases) or survival (31 cases) group according to their hospitalization outcomes, and clinical data and antibacterial treatment scheme after infection were collected. The clinical features of the two groups and the correlation between different antibacterial treatment regimens and prognosis were compared. Logistics regression model was used to analyze the risk factors for death in CRKP-infected patients.Results:The all-cause mortality rate of patients with CRKP bloodstream infection during hospitalization was 38%(19/50). The age ((66.89±18.13) vs. (55.06±14.39) years old, t=2.555, P=0.014), charlson's comorbidity index ((6.11±2.87) vs. (3.19±1.97), t=4.256, P<0.001) of the death group was higher than that of the survival group. The proportion of patients with chronic obstructive pulmonary disease (42.1%(8/19) vs. 3.2%(1/31), χ2=9.574, P=0.002), Charlson's comorbidity index ≥5 (68.4%(13/19) vs. 22.6%(7/31), χ2=10.314, P=0.001), septic shock (36.8%(7/19) vs. 6.5%(2/31), χ2=5.456, P=0.020), source of lung infection (36.8%(7/19) vs. 9.7%(3/31), χ2=3.868, P=0.049) was higher in death group than those in survival group. Kaplan-meier survival curve showed that the 30-day mortality of appropriate targeted treatment was lower than that of inappropriate targeted treatment ( χ2=8.138, P=0.004). Multivariate analysis showed that septic shock ( OR=56.363, 95% CI: 4.309-737.273, P=0.002) and charlson's comorbidity index ≥5 ( OR=18.605,95% CI: 1.813-190.896, P=0.014) were independent risk factors for mortality in patients with bloodstream CRKP infection. Conclusion:Appropriate targeted therapy can reduce 30-day mortality in patients with CRKP bloodstream infection. In order to reduce the risk of mortality, we should prevent the occurrence of septic shock and strengthen the diagnosis and treatment of patients with Chalson's comorbidity index ≥5.

Objective:To explore the effect and mechanism of astaxanthin on acute kidney injury in rats with full-thickness burns.Methods:Forty-eight male Sprague Dawley rats of 8 to 10 weeks were divided into sham injury group, simple burn group, burn+ vehicle group, burn+ low-dose astaxanthin group, burn+ medium-dose astaxanthin group, and burn+ high-dose astaxanthin group according to the random number table, with 8 rats in each group. The back skin of rats in sham injury group were immersed in warm water of 20 ℃ for 15 s to simulate burn injury, and the back skin of rats in the other 5 groups were immersed in boiled water of 100 ℃ for 15 s to inflict full-thickness burn of 30% total body surface area. Fluid resuscitation was performed in rats in the 5 groups except of sham injury group immediately and 6 h after injury. At 30 min after injury, the rats in sham injury group and simple burn group were injected with 1 mL/kg normal saline via tail vein, rats in burn+ vehicle group were injected with 1 mL/kg astaxanthin solvent via tail vein, and rats in burn+ low-dose astaxanthin group, burn+ medium-dose astaxanthin group, and burn+ high-dose astaxanthin group were respectively injected with 5, 10, 20 mg/kg astaxanthin solution of 5, 10, 20 mg/mL via tail vein. The renal tissue was collected at post injury hour (PIH) 48, and hematoxylin eosin staining was used for histopathological observation and renal tubular injury score. At PIH 48, the venous blood was collected for detecting serum creatinine level through blood biochemical analyzer, and blood urea nitrogen (BUN) level was detected by enzyme-linked immunosorbent assay. The renal tissue was collected to detect the mRNA expressions of myeloperoxidase (MPO), interleukin-1β (IL-1β), and IL-6 by real-time fluorescent quantitative reverse transcription polymerase chain reaction method, and the protein expressions of Toll like receptor 4 (TLR4), phosphorylated nuclear factor kappa B (p-NF-кB) p65, and heme oxygenase 1 (HO-1) were detected by Western blotting. Besides, the expression of HO-1 in renal tissue was detected by immunofluorescence method. Data were statistically analyzed with Kruskal-Wallis H test, Dunn-Sidák correction, one-way analysis of variance, and Bonferroni method. Results:(1) At PIH 48, there were no inflammatory cell infiltrating and degeneration or necrosis of cells in renal tissue of rats in sham injury group, and the structure of renal tubules was intact. The renal tubules of burn rats in each group showed injury manifestation of separation between epithelial cell and basement membrane, and vacuole cells and lysate protein aggregation. The injury degree of renal tissue of rats in burn+ high-dose astaxanthin group was obviously decreased compared with that in simple burn group. (2) At PIH 48, compared with that of sham injury group, the renal tubular damage scores of rats in simple burn group, burn+ vehicle group, burn+ low-dose astaxanthin group, and burn+ medium-dose astaxanthin group were significantly increased ( P<0.05 or P<0.01). Compared with those of simple burn group and burn+ vehicle group, the renal tubular damage scores of rats in burn+ medium-dose astaxanthin group and burn+ high-dose astaxanthin group were significantly decreased ( P<0.05 or P<0.01). Compared with that of burn+ low-dose astaxanthin group, the renal tubular damage score of rats in burn+ high-dose astaxanthin group was significantly decreased ( P<0.01). (3) At PIH 48, the level of serum creatinine of rats in sham injury group was (2.42±0.06) mg/L, which was significantly lower than (6.11±0.11), (6.48±0.08), (5.79±0.09), (4.03±0.12) mg/L of simple burn group, burn+ vehicle group, burn+ low-dose astaxanthin group, and burn+ medium-dose astaxanthin group ( P<0.05 or P<0.01). The level of BUN of rats was (21.9±1.3) mmol/L in sham injury group, significantly lower than (32.1±7.4) mmol/L of simple burn group and (30.2±4.8) mmol/L of burn+ vehicle group ( P<0.05 or P<0.01). At PIH 48, compared with those of simple burn group and burn+ vehicle group, the levels of serum creatinine and BUN of (16.0±2.9) mmol/L in burn+ medium-dose astaxanthin group, serum creatinine of (3.02±0.08) mg/L and BUN of (14.5±2.9) mmol/L in burn+ high-dose astaxanthin group, and serum creatinine of (22.8±5.5) mmol/L of rats in burn+ low-dose astaxanthin group were significantly decreased ( P<0.05 or P<0.01). At PIH 48, compared with those of burn+ low-dose astaxanthin group, the levels of serum creatinine and BUN of burn+ high-dose astaxanthin group and serum creatinine of burn+ medium-dose group were obviously decreased ( P<0.05 or P< 0.01). (4) At PIH 48, compared with those of sham injury group, the mRNA expressions of MPO, IL-1β, and IL-6 in renal tissue of rats in simple burn group, burn+ vehicle group, burn+ low-dose astaxanthin group, and burn+ medium dose astaxanthin group, and the mRNA expressions of IL-1β and IL-6 in renal tissue of rats in burn+ high-dose astaxanthin group were obviously increased ( P<0.01). Compared with those of simple burn group and burn+ vehicle group, the mRNA expressions of MPO, IL-1β, and IL-6 in renal tissue of rats were significantly decreased in burn+ low-dose astaxanthin group, burn+ medium-dose astaxanthin group, and burn+ high-dose astaxanthin group ( P<0.01). Compared with those of burn+ low-dose astaxanthin group, the mRNA expressions of MPO, IL-1β, and IL-6 in renal tissue of rats were significantly decreased in burn+ medium-dose astaxanthin group and burn+ high-dose astaxanthin group ( P<0.01). The mRNA expressions of MPO, IL-1β, and IL-6 in renal tissue of rats in burn+ high-dose astaxanthin group were significantly decreased compared with those of burn+ medium-dose astaxanthin group ( P<0.01). (5) At PIH 48 h, compared with those of sham injury group, the protein expressions of TLR4 and p-NF-кB p65 in renal tissue of rats in simple burn group, burn+ vehicle group, burn+ low-dose astaxanthin group, and burn+ high-dose astaxanthin group were obviously increased ( P<0.01). Compared with those of simple burn group, the protein expressions of TLR4 and p-NF-кB p65 in renal tissue of rats in burn+ low-dose astaxanthin group, burn+ medium dose astaxanthin group, and burn+ high-dose astaxanthin group were significantly decreased ( P<0.01). (6) The results of Western blotting combined with immunofluorescence method showed that compared with that of sham injury group, the protein expression of HO-1 in renal tissue of rats in burn+ vehicle group, burn+ low-dose astaxanthin group, burn+ medium-dose astaxanthin group, and burn+ high-dose astaxanthin group were significantly increased at PIH 48 ( P<0.01), and the protein expression of HO-1 in renal tissue of rats in burn+ medium-dose astaxanthin group and burn+ high-dose astaxanthin group was significantly increased compared with that of simple burn group ( P<0.01). Conclusions:Astaxanthin can attenuate the structural damage and functional decline of renal tissue and regulate the release of injury-related inflammatory factors, thus to protect the rats from acute kidney injury after burn. The HO-1/TLR4/NF-кB signaling pathway is the main regulatory mechanism of astaxanthin to achieve anti-inflammation-based renoprotection.

Objectives:To evaluate the clinical value of the Paris system for reporting urinary cytology (TPS) in the diagnosis of urothelial carcinoma (UC).Methods:A total of 1 744 cytological diagnostic records (from 751 cases) were collected retrospectively. All specimens were voided urines and histopathology as the gold standard. The sensitivity and specificity of urinary cytological diagnosis of UC and risk of high grade malignant (ROHM) in each diagnostic category were compared.Results:There were 360 cases with histopathology. The percentage of negative for high-grade urothelial carcinoma (NHGUC) was 30.1% (226/751), atypical urothelial cells (AUC) was 29.8% (224/751), suspicious for high-grade urothelial carcinoma (SHGUC) was 16.8% (126/751), high grade urothelial carcinoma (HGUC) was 21.2% (159/751), and non-urothelial malignancy (NUM) was 2.1% (16/751). The histpathologic ROHM corresponding to each cytological diagnosis category were 27.3% for NHGUC, 32.7% for AUC, 74.7% for SHGUC, 96.6% for HGUC and 100.0% for NUM, respectively. ROHM of SHGUC was significantly higher than that of AUC group, and the difference between the two groups was statistically significant ( P＜0.001). ROHM of HGUC group was significantly higher than that of SHGUC group, and the difference was statistically significant ( P＜0.001). With SHGUC as the cut-off value, the sensitivity and specificity of cytological diagnosis of HGUC were 76.7% (165/215) and 85.7% (18/21), and with HGUC as the cut-off value, the sensitivity and specificity of cytological diagnosis of HGUC were 53.0% (114/215) and 100.0% (21/21), respectively. Conclusions:Urine cytology has high sensitivity and specificity in the diagnosis of HGUC. The malignant risk of TPS varies with different diagnosis category. The high malignant risk population in cancer hospital leads to the relatively high malignant proportion and ROHM in each diagnosis category. Urinary cytology TPS reporting system is helpful to clinical management and has good clinical application value.
