The main maridians were Stomach Meridian of Foot-Yangming, Spleen Meridian of Foot-Taiyin, and Gallbladder Meridian of Foot-Shaoyang, accounting to for 1626 times (93.66%). Cluster analysis achieved other four groups of acupoint selection based on syndrome differentiation.ConclusionLocal acupoints and dialectical point selection were important principle in treating knee osteoarthritis combined with acupoint selection based on syndrome differentiation.

Objective To detect the dynamic changes of the level of serum Clara cell protein(CC16)and surfactant protein-D(SP-D)in rats with pulmonary fibrosis induced by bleomycin and to evaluate their value in early diagnosis of pulmonary fibrosis. Methods Sixty Wistar rats were randomly divided into two groups, the control group and bleocin-induced pulmonary fibrotic group,with 30 rats in each group. The rats were killed at 1,3,7,14 and 28 days of treatment Pathology changes of lung tissue were observed by HE,Masson stain,alkaline hydrolysis to assess the hydroxyproline concentration of lung tissue, enzyme-linked immunosorbent assay (ELISA) was used to measure the levels of serum CC16 and SP-D. Results The hydroxyproline concentration of lung tissue in the pulmonary fibrotic group ((913. 1 ±69. 3) μg/g) were higher than those of the control group ((790. 5 ± 36. 8) μg/g) from the seventh day(P <0. 05). The levels of serum CC16 of the pulmonary fibrotic group((27. 34 ± 0. 32) μg/L) were lower than those of the control group((27. 85 ±0. 32)μg/L) since the third day(P<0. 05) ,and tended to decrease with the development of the disease. However,the levels of SP-D of the former group were always higher(P <0. 05), and tended to increase with the development of the disease. Conclusions The levels of serum CC16 and SP-D changed considerably in early-stage of pulmonary fibrosis, thus might be used as biomarker for early diagnosis and have some value for pathogenesis of pulmonary fibrosis.

Objective To assess the safety and feasibility of CT-guided percutaneous argon-helium cryoablation in the treatment of adrenal tumors.Methods 1 7 patients with adrenal tumors were treated with CT-guided percutaneous argon-helium cryoablation. Three of these patients were retreated second cryoablation three months later due to the lager tumor diameters.Percutaneous tran-scatheter arterial embolization was performed in four patients because of rich blood supply before cryoablation.Continuous arterial blood pressure monitoring was performed in eight pheochromocytoma patients.Results Technical success was achieved in all pa-tients.There were no serious complications.Eight pheochromocytoma patients experienced a significant increase in systolic blood pressure and diastolic pressure when compared with the basic values (P <0.05).There were no enhancement on enhanced CT and/or up-take on FDG PET-CT in the ablated zones during the follow-up period (3-24months).Conclusion It is safety and efficacy of CT-guided percutaneous argon-helium cryoablation for adrenal tumor.It might be initial treatment of choice for the patients who were not suitable for resection.

Objective To investigate the feasibility, safety and technical superiority of mechanical thrombectomy using a direct aspiration first-pass thrombectomy (ADAPT) in treatment of patients with acute cerebral artery occlusion. Methods A retrospective study was conducted on all patients with acute ischemic stroke treated with mechanical thrombectomy in our institution from January 2013 to August 2016.Patients using ADAPT or stent retriever as a first-line endovascular procedure were compared for clinical characteristics, procedural variables and clinical outcomes. The technical superiority of ADAPT was analyzed in depth. Results During observation period, a total of 91 cases were performed endovascular treatment with mechanical thrombectomy. ADAPT was designed in 46 cases as a first-line endovascular procedure and was utilized in 38 cases (82.6%;ADAPT group), while primary stent retriever thrombectomy was performed in 21 patients(stent group). There was no significant difference in baseline clinical or radiographic factors between ADAPT and stent groups. Although rates of good neurological outcome (modified Rankin Scale(mRS) score≤2) at 90 days were similar between the ADAPT and stent groups (61%(23/38) vs 48%(10/21), P=0.247), National Institute of Health Stroke Scale (NIHSS) score at seven days (6.0(2.0, 9.3) vs 9.0(5.5, 18.5),Z=-2.031,P=0.021) and full recovery rate of neurological outcome (mRS score=0, 37%(14/38) vs 10%(2/21), P=0.022) were significantly better in the ADAPT group than in the stent group. There were no significant differences in rates of embolus to new territory (21%(8/38) vs 29%(6/21), P=0.365), Thrombolysis In Cerebral Infarction (TICI) 2b/3 grade revascularization (84%(32/38) vs 81%(17/21), P=0.507) and symptomatic intracerebral hemorrhage (0%(0/38) vs 10%(2/21), P=0.123) between the ADAPT and the stent groups, but the figures were better in the ADAPT group. Conclusions Mechanical thrombectomy using ADAPT is feasible and safe compared with stent retriever, with higher full recovery rate of neurological outcome and better NIHSS score.It is a method worthy of further exploration for endovascular mechanical recanalization.

BACKGROUND:The laparoscopy is superior to open surgery for being less invasive, inducing mild stress reaction and allowing quick recovery after operation, however the effects of laparoscopy on perioperative serum cytokine levels are controversial, and only a few studies discuss these effects among pediatric patients.OBJECTIVE: To compare the changes in perioperative cytokine levels and their clinical significance in pediatric patients undergoing laparoscopy and open surgery.DESrGN: Non-randomized concurrent controlled observation.SETTTNG: Department of Urology in Xijing Hospital of the Fourth Military Medical University of Chinese PLA.PARTICT PANTS: From May 2004 to December 2006, 135 pediatric patients for elective operation were recruited from Department of Urology in Xijing Hospital of the Fourth Military Medical University of Chinese PLA. Sixty-five patients were scheduled for laparoscopic surgery while the remaining 70 patients for open surgery.METHODS: Serum levels of interleukin-1 beta (IL-1β), IL-6, IL-10 and tumor necrosis factor-alpha (TNF-α) were measured at 24 hours before operation, and 3, 24, 48 hours after operation respectively. Duration of hospitalization time of all the children was also recorded.MAIN OUTCOME MEASURES: Levels of IL-1β, IL-6, IL-10 and TNF-α of all the patients were measured 24 hours preoperatively, and 3, 24, 48 hours postoperatively.RESULTS: All the 135 cases were included for statistical analysis. ①There were no significant perioperative changes in cytokine levels after laparoscopic surgery (P ＞ 0.05). In the open surgery group, IL-1β and IL-6 levels increased significantly at 3 and 24 hours after operation (P ＜ 0.05), and normalized within 48 hours postoperatively. No significant perioperative differences were found in IL-10 and TNF-α levels (P ＞ 0.05). The levels of IL-1β and IL-6 were significantly higher in the open surgery group than in the laparoscopic surgery group (P ＜ 0.05). ②Duration of hospitalization was shorter in the laparoscopic surgery group than in the open surgery group [(3.5±1.0), (7.5+1.5) days, P＜ 0.05].CONCLUSTON: Pediatric patients undergoing laparoscopic surgery had less perioperative changes in cytokine levels and quicker recovery.

BACKGROUND: The nutritional support, as well as the water and electrolyte balance during the perioperative period in the renal transplantation recipients at diuresis stage are important to the functional restoration of transplanted kidneys.OBJECTIVE: To explore the method and opportunity of the nutritional support and the handling of the water and electrolyte balance in perioperative period of renal transplantation.DESIGN, TIME AND SETTING: A retrospective clinical analysis was performed in the Department of Urology, Xijing Hospital from June 2003 to June 2007.PARTICIPANTS: Ninety-six patients of chronic renal failure underwent allograft renal transplantation. They comprised 59 males and 37 females, aged 17-67 years, with a mean of 35.7 years.METHODS: The perioperative physiological features of the renal transplantation recipients were summarized retrospectively. The recipients' condition during the perioperative period was divided into two stages at the opening point of allograft blood current. The vital signs of the patients maintained at a stable level before operation. All patients received blood transfusion since the operation began, and were supplemented with albumin before opening the vessels. Urinary production exceeding 100 mL per hour indicated the beginning of fluid replacement, which was a simplified transfusion for the patients at diuresis stage following renal transplantation.MAIN OUTCOME MEASURES: Blood inosine, urea nitrogen, electrolyte, blood sugar and urine of the patients were detected at one day postoperatively.RESULTS: During 12-16 hours postoperatively, the urinary production was 260-1 200 mL, average 520 mL per hour. Blood routine test showed 8 cases developed mild hyponatremia, accounting for 8.3%, 3 cases occurred high potassium and healed after renal functional recovery, 1 case presented low potassium and healed with supplement therapy. There were no abnormal changes of blood chlorine. The blood glucose among 21 cases (21.9%) was higher than the normal level, and recovered following hormone maneuver. The electrolytes and blood glucose were detected to be normal in other patients, without any case with low calcium or magnesium. The urine specific gravity arranged during 1.010-1.015.CONCLUSION: The colloid such as erythrocytes, blood plasma and albumin should be mainly infused before the opening of allograft blood current. And the water and electrolytes is recommended to administrate promptly and regularly during the diuresis stage. The healing of the stoma benefits from the adequate nutritional support. The metabolic acidosis still should be prevented when the urinary production returns normal.

Objective:To investigate the feasibility of targeted imaging and therapy of prostate cancer using nanocomposite probes composed of fluorescent magnetic nanoparticles(FMCNPs) and single chain Fv(ScFv) antibody specific for gama-seminoprotein.Methods:The nanocomposite probes(FMCNPs-ScFv) were prepared by conjugating fluorescent magnetic nanoparticles with singlegama-chain Fv antibody specific gama-seminoprotein,and were characterized by high resolution transmission electron microscopy,fluorescent spectrum and magnetic spectrum.Nanocomposite probes were incubated with prostate cancer LNCaP cells,and the targeting results of nanocomposite probes were observed by fluorescent microscopy.The cytotoxicity effect of the nanocomposite probes was measured by MTT.Nude mice models of prostate cancer were established and identified by immunohistochemistry method.The nanocomposite probes were injected into nude mice via tail vein.The distribution of nanocomposite probes in the nude mice was observed by Micro-animal imaging system,targeted imaging of the prostate cancer was observed by MR instrument.The nude mice with prostate cancer were irradiated with 100 W magnetic field for 30 min,and the changes of tumor sizes were observed.Results:The FMCNPs-ScFv nanocomposite probes were successfully prepared.Nanocomposite probes entered into the cytoplasm of cancer cells and exhibited low cytotoxicity effect.Nude mice model with prostate cancer were successfully fabricated;the nanocomposite probes distributed quickly in the main organs of mice,and gradually concentrated on the tumor tissues within 24 h.MR images showed that the tumor images were gradually enhanced from 6 h to 24 h after injection of the nanocomposite probe.Four days after magnetic irradiation,the tumors in the nude mice grew slower compared with the control nude mice(P

Objective To investigate the feasibility,effectiveness,and technical superiority of Solumbra thrombectomy for treatment of acute large cerebral artery occlusion stroke.Methods 32 patients who had acute large cerebral artery occlusion stroke and received mechanical thrombectomy in TEDA Hospital of Tianjin between January 2013 and August 2016,were divided into two groups:stent group(with conventional stent-retrievers,n=21) and Solumbra group (with Solumbra thrombectomy,n =11).Clinical characteristics,variables correlated with operation,and clinical outcomes were compared and analyzed retrospectively.Results There were no differences in basic clinical and radiographic parameters between stent group versus Solumbra group (all P＞0.05).Moreover,there were no differences between Solumbra group versus Stent group in rates of embolus to new territory(18.2 ％ vs.28.6％,P=0.425),in times of thrombectomy(2.2± 1.0 vs.2.4± 1.3,P=0.657),in nonsymptomatic intracranial hemorrhage (18.2％ vs.14.3％,P =0.572),in symptomatic intracranial hemorrhage(18.2％ vs.9.5％,P =0.427),in TICI 2b/3 revascularization(81.8％ vs.81.0％,P =0.670),in puncture-to-reperfusion time[(66.4±39.0)min vs.(51.6±34.5)min,P=0.279],and in NIHSS at 7 days(11.6 ± 7.7 vs.11.3 ± 7.2,P =0.925).A modified Rankin Scale(mRS ≤2) is a variable of recovery of function and good clinical outcome at 90 days.The levels of mRS were similar(P =0.490)between Solumbra and stent groups,but there was a tendency to higher rate of good clinical outcome at 90 days in Solumbra group (63.6％,7/11)than in stent group (47.6％,10/21).Conclusions Solumbra thrombectomy as intravascular revascularization technique is an effective and safe strategy for endovascular recanalization of acute large cerebral artery occlusion stroke.Compared with conventional Stent-Retriever thrombectomy,Solumbra thrombectomy has a good clinical outcome tendency at 90 days after operation.

Objective To compare the clinical features and prognosis between dermatomyositis-associated interstitial lung disease (DM-ILD) and idiopathic pulmonary fibrosis (IPF).Methods Patients with interstitial lung disease with dermatomyositis (DM-ILD) or idiopathic pneumonia fibrosis (IPF) from January 2003 to March 2014 in the third affiliated hospital of Sun Yat-sen University were included.Results Among the 64 patients enrolled,44 were DM-ILD and 20 were IPF.IPF was more common in the elderly (P =0.000),men (P =0.004) and smokers (P =0.000),and its high-resolution computed tomography (CT) mostly showed grid shadow (P=0.014) and honeycomb shadow (P=0.000).DM-ILD usually had cough symptoms (P =0.025).High-resolution CT showed patchy (P =0.048) and banded (P =0.000).Glucocorticoid (P =0.000) and immunosuppressive agents (P =0.000) were commonly used in the treatment of DM-ILD.However,there was no significant difference in 90d mortality between the two groups (P ＞ 0.05).Conclusions IPF is more common in the elderly,men and smokers,and its high-resolution CT mostly shows grid shadow and honeycomb shadow,distribution is diffuse.DM-ILD often has cough symptoms,and its high resolution CT is mostly plaques and streaky shadows.Glucocorticoids and immunesuppressants are commonly used in DM-ILD,but there is no significant difference in 90-day mortality between them.
