OBJECTIVE: To evaluate the advantage of Gukangling Decoction (GKLD), a compound traditional Chinese herbal medicine, combined with technetium [(99)Tc] methylene diphosphonate injection ((99)Tc-MDP) in treating osteoporosis in rabbits. METHODS: A rabbit model of osteoporosis was established by intramuscular injection of dexamethasone (DX). Fifty-six rabbits were divided into 8 groups: Group A, B, C, D, E, F, G and H. Rabbits in groups A and B were intramuscularly injected normal saline as normal control, groups C and D were untreated groups, rabbits in group E were treated by (99)-MDP, rabbits in group F were treated by aminodiphosphate, rabbits in group G were treated by GKLD, and rabbits in group H were treated by (99)-MDP and GKLD. Rabbits in groups A and C were executed to demonstrate the establishment of the rabbit model of osteoporosis at the 8th week of experiment. Rabbits in the other six groups were executed after 16-week experiment (8-week treatment), and then bone structure and cell shape were observed by electron microscope, X-ray, CT and emission computed tomography (ECT). Bone density, biomechanical parameters, the levels of bone specific alkaline phosphatase (BALP) and bone Gla protein (BGP) were measured too. RESULTS: After 8-week of intramuscular injection of DX, the bone trabecula in group A were regular and showed normal configuration, while the bone trabecula in group C were sparse, ruptured and showed damaged form. The bone density and biomechanical parameters in group A were higher than those in group C, indicating that the rabbit model of osteoporosis was established successfully. At the 9th week of experiment, the results of cell pathology in group D showed that the bone trabeculas were sparse, ruptured, defected or had hollow section, but the bone trabeculas in group B were regular and dense. The bone trabeculas in groups H and E were restored, and were thicker than those in group D. The bone quality in groups H and E was better than group D significantly, the bone quality in group F was better than group G, and the bone quality in group G was better than group D slightly. CONCLUSION: GKLD combined with (99)-MDP had superiority in treating osteoporosis of rabbits as compared with the respective single therapy.

Objective To discuss the effect of intra-operative and post-operative hyperthermic intraperitoneal lavage chemotherapy for Ⅲb and IV gastric cancer on post-operative peritoneal metastasis and survival rate.Methods The clinical data of 31 cases of gastric cancer(control group)who underwent operation only and 50 cases(chemotherapy group)who receved operation combined with intra-operative and post-operative hyperthermic intra-peritoneal lavage chemotherapy were comparatively studied.Results The survival rate of control group after 2 years and 3 years was lower than that of the chemotherapy group,and the intraperitoneal recurrence raue of cootrol group after 2 years and 3 years was higher than that of chemotherapy group.Conclusions Intra-operative and post-operative hyperthermic intraperitoneal lavage chemotherapy for gastric cancer has important significance in prevention and treatment of peritoneal metastasis and can improve survival rate.

A resonance light scattering(RLS) method for the determination of critical micelle concentration(CMC) of sodium dodecyl benzene sulfonate(SDBS) was proposed. Under room temperature, the RLS intensity of the SDBS system increased with increasing SDBS concentration. And when the concentration of SDBS approached CMC, the RLS intensity had increased sharply. The RLS peaks were appeared at 330 nm and 396 nm, respectively. The plot of the RLS intensity at 396 nm versus SDBS concentration was S-Curve. The concentration of SDBS at the intersection point of two tangents to S-curve was considered as SBDS CMC. This result was consistent with the results of the pyrene probe fluorescence spectrometry and electrical conductivity method. The influences of the concentration of Ca2+ on the aggregation behave of SDBS and SDBS-emulsion OP(OP) systems were studied by the RLS method. The results indicated that the mixed

Objective:To explore the effect of laparoscopic minimally invasive on anorectal dynamics and serum carcino-embryonic antigen (CEA) and carbohydrate antigen 724 (CA724) in patients with rectal cancer.Methods:38 cases of rectal cancer patients were selected as the research group from March 2014 to March 2016 and 40 cases of non neoplastic intestinal polyps as control group,Preoperative anorectal dynamics index (anal resting pressure (ARP),rectal resting pressure (RRP)and anal maximal contraction pressure (MSP),rectal maximum tolerated volume (MTV) of two groups were compared,Preoperative and 3 d,1,2 weeks after operation of serum CEA and CA724 levels were detected in the research group and the clinical curative effect was observed.Results:There was no significant difference of ARP,RRP,MSP,MTV before operation in research group compared with the control group(P＞0.05),and was significantly reduced 2,4 weeks after operation(P＜0.05),then gradually restored,and basically recovered to the preoperative level 12 weeks after operation.There was no significant difference of serum CEA and CA724 levels 3 d after operation compared with preoperative in research group (P＞0.05),and were significantly lower 1,2 weeks after operation compared with preoperative (P＜0.05).The clinical effective rate was 65.8％.Conclusion:Efficacy of laparoscopic minimally invasive in treatment of rectal cancer is effective,can effectively reduce the levels of tumor markers,although there are some influence on anorectal dynamics,but it can be returned to normal in the short term.

Objective To investigate the diagnostic performance of ADC value for predicting proliferation and invasiveness of cervical squamous cell carcinoma (SCC).Methods Totally 96 patients with pathologically confirmed SCC underwent preoperative conventional MRI and DWI.Mini-ADC value,mean-ADC value and mini-ADC ratio (mini-ADC/meam ADC) were measured and compared for various patient groups divided based on Ki-67 labeling index and clinicopathological characteristics.Results The mini-ADC values were significantly lower in patients with high Ki-67 expression,tumor size ≥4 cm,high FIGO staging,low pathological grade,depth of cervical stromal infiltrating ≥ 1/2,parametrial involvement,lymphovascular invasion (LVI),lymph node metastasis and perineural invasion (PNI,all P＜ 0.05).Compared with mean-ADC value and mini-ADC ratio,mini-ADC value exhibited the most effective diagnostic performance in predicting clinicopathological characteristics with the highest areas under the ROC curve and efficacy.Mini-ADC value showed negative correlation with Ki-67 index (r=-0.48,P＜0.001) as well as other clinicopathological characteristics,including tumor size,FIGO staging,pathological grading,depth of cervical stromal infiltrating,parametrial involvement,LVI,lymph node metastasis and PNI (r=-0.36,-0.34,-0.27,-0.40,-0.33,-0.60,-0.61,-0.41,respectively,all P＜0.05).Conclusion Mini-ADC value can effectively reflect the proliferation and invasiveness of cervical SCC.

A qualitative analysis was developed to identify different ingredients from three Ginkgo biloba preparations(including Yinxingye Diwan, extract of Ginkgo biloba leaves tablets and Yinxingtongzhi Diwan)based on high resolution mass spectrometry and metabolomics technology. An XSELECT HSS T3(4. 6 mm×150 mm, 3. 5 μm)column was used for separation, with the mobile phases consisting of acetonitrile and water containing 0. 1% formic acid. The column temperature was set at 40 °C. Negative ion mode was used for mass spectrometric data acquisition. Through partial least squares projection to latent structure-discriminant analysis(PLS-DA), we firstly found the different compounds among different Ginkgo biloba preparations. Subsequently, the compounds displaying different abundance levels via database searching and literature matching were identified. Finally, we identified 21 different compounds between the extract of Ginkgo biloba leaves tablets and Yinxingye Diwan, which mostly belong to the organic acids and flavonols families. Quantitative analysis showed that the ingredients which had higher abundance in extract of Ginkgo biloba leaves tablets were mainly organic acids, whereas those exhibiting higher levels in Yinxingye Diwan are flavonols. We also identified 12 different ingredients between the Yinxingye Diwan and Yinxingtongzhi Diwan, which were flavonols, sciadopitysin and organic acids. The results of this study are useful for studying different chemical constituents from distinct Ginkgo biloba preparations.

Objective: To explore the effects of citric acid on patients with severe burn complicated with acute renal injury treated by continuous renal replacement therapy (CRRT). Methods: Medical records of 83 patients with large area of burn complicated with acute renal injury admitted to intensive care unit (ICU) of our department from January 2015 to December 2018 and meeting the inclusion criteria were analyzed retrospectively. The patients were divided into heparin group [n=43, 25 males and 18 females, aged (35.0±2.5) years] and citric acid group [n=40, 22 males and 18 females, aged (37.0±6.6) years] according to different anticoagulation methods. After admission, routine support treatment and CRRT were performed after being diagnosed with acute renal injury in patients in 2 groups. Patients in heparin group were treated with low molecular weight heparin for anticoagulation with first dosage of 20 U/kg and an increase of 2.5 to 5.0 U per hour, and patients in citric acid group were given citric acid of 0.02 g/mL with dosage of 150~200 mL/h for anticoagulation. The use time of blood filter, recovery time of urine volume, and time of staying in ICU, and platelet count, activated partial thromboplastin time (APTT), prothrombin time (PT), and serum creatinine, urea nitrogen, cystatin C, procalcitonin, C-reactive protein, and neutrophil, leukocyte count, blood sugar, aspartate aminotransferase (AST), alanine aminotransferase (ALT), and heart rate, body temperature, and mean arterial pressure before treatment and post treatment hour (PTH) 24 were recorded. Besides, occurrence of hemorrhage, hypocalcemia, metabolic acidosis, metabolic alkalosis, and death within 28 days post injury were recorded. Data were processed with t test and chi-square test. Results: The use time of blood filter of patients in citric acid group was (28.7±3.2)h, significantly longer than (19.4±2.6) h in heparin group (t=14.139, P<0.01). The recovery time of urine volume and time of staying in ICU of patients in citric acid group were respectively (7.6±0.9) and (9.6±1.3) d, significantly shorter than (9.2±1.5) and (11.2±1.8) d in heparin group (t=5.516, 4.697, P<0.01). Before treatment, there were no statistically significant differences in platelet count, APTT, and PT of patients in 2 groups (t=1.235, 0.515, 1.279, P>0.05). At PTH 24, the platelet count of patients in citric acid group was significantly higher than that in heparin group (t=10.947, P<0.01), and APTT and PT of patients in citric acid group were significantly shorter than those in heparin group (t=7.069, 9.142, P<0.01). Before treatment, there were no statistically significant differences in serum creatinine, urea nitrogen, and cystatin C of patients in 2 groups (t=1.684, 1.878, 1.472, P>0.05). At PTH 24, the serum creatinine, urea nitrogen, and cystatin C of patients in citric acid group were significantly lower than those in heparin group (t=7.778, 9.776, 5.117, P<0.01). Before treatment, there were no statistically significant differences in serum procalcitonin and C-reactive protein of patients in 2 groups (t=1.413, 0.898, P>0.05). At PTH 24, the serum procalcitonin and C-reactive protein of patients in citric acid group were significantly lower than those in heparin group (t=2.635, 2.297, P<0.05). Before treatment, there were no statistically significant differences in neutrophil, leukocyte count, blood sugar, AST, and ALT of patients in 2 groups (t=0.555, 0.816, 0.470, 1.896, 0.982, P>0.05). At PTH 24, the neutrophil, leukocyte count, blood sugar, AST, and ALT of patients in citric acid group were significantly lower than those in heparin group (t=2.054, 3.314, 7.185, 2.151, 3.013, P<0.05 or P<0.01). Before treatment, there were no statistically significant differences in heart rate, body temperature, and mean arterial pressure of patients in 2 groups (t=1.406, 0.474, 0.720, P>0.05). At PTH 24, the heart rate, body temperature, and mean arterial pressure of patients in citric acid group were significantly lower than those in heparin group (t=2.307, 4.498, 2.056, P<0.05 or P<0.01). The incidence of hemorrhage of patients in citric acid group while in hospital was significantly lower than that in heparin group (χ²=4.949, P<0.05). There were no statistically significant differences in incidence of hypocalcemia, metabolic acidosis, metabolic alkalosis, and death rate within 28 days post injury of patients in 2 groups while in hospital (χ²=3.346, 0.884, 0.297, 0.324, P>0.05). Conclusions Citric acid has significant anticoagulant effect on patients with large area of burn complicated with acute renal injury treated by CRRT, which can prolong the use time of the blood filter, shorten the recovery time of urine volume and time of staying in ICU, improve renal function indexes, blood biochemical indexes, and inflammation indexes, maintain the stability of internal environment, and reduce the risk of hemorrhage.
