Objective: This study aimed to investigate the effects and side effects of Jinlong Capsule with concurrent three-dimen-sional conformal radiotherapy for advanced primary hepatic carcinoma. Methods: A total of 85 patients with inoperable primary hepat-ic carcinoma were randomly divided into a research group and a control group. Forty-two cases in the control group were treated with three-dimensional conformal radiotherapy alone, whereas 45 cases in the research group were treated with three-dimensional conformal radiotherapy and Jinlong Capsule oral administration. All cases were irradiated with 6 MV X-rays, 2 Gy per day, 5 days a week to a to-tal dose of 60 Gy in 6 weeks. Jinlong Capsule (1 g) was administered orally three times daily until disease progression for at least one year. The short-term therapeutic effect and adverse events were evaluated for 2 months after treatment. The long-term therapeutic effect was assessed at the end of follow-up. Results: The objective response rate of the research group was significantly higher than that of the control group at 74.4% and 47.6%, respectively (P=0.011). The disease control rates were 97.7% and 85.3% (P=0.030) for the re-search and control groups, respectively. No obvious difference was found between the complete response rates of the two groups, 20.9% and 14.3% (P=0.422). The 1- and 3-year overall survival rates of the research group (74.4% and 34.9%) were significantly high-er than those of the control group (66.7% and 16.7%) at P=0.046. The 1- and 3-year progression free survival rates of the research group (74.4% and 27.9%) were significantly higher than those of the control group (61.9% and 9.5%) at P=0.038. The main adverse events were grade 1–2 bone marrow suppression, abdominal distension, nausea, vomiting, and transaminase elevation. No obvious dif-ference was observed between the adverse events in the two groups. Conclusion: The short- and long-term effects of the combination therapy of Jinlong Capsule and three-dimensional conformal radiotherapy on primary hepatocellular carcinoma were significantly high-er than those of three-dimensional conformal radiotherapy alone. The patients also tolerated the adverse effects.

Objective:To establish an algorithm on the turnover ratio of drug inventory. Methods: According to the employed method in the commercial field on calculating the inventory turnover and the requirements in the review of three level hospitals by the National Health and Family Planning Commission, an appropriate method for calculating the turnover rate of drug inventory was de-duced. Meanwhile, a corresponding program was performed for the verification. Results:Only the day turnover could be obtained ac-cording to the algorithms on the inventory turnover in commercial field, and the circumstances of the sales could be replaced by the cur-rent sales to obtain the statistics at any given time, while there was remarkable difference between the calculated results and the actual results of some species. If the time in store was chosen as the statistical index, the problem could be avoided. Conclusion:The meth-od with drug storage time as the statistical index can calculate the inventory turnover ratio at any time precisely, which also can be pro-grammed automatically, and the proportion of available varieties meets the inspection requirements.

BACKGROUND: Although bone tissue engineering has been developed rapidly, ideal scaffold materials are deficient and the ability of tissue engineered bone constructed in vitro was reported inconsistently.OBJECTIVE: To study the ectopic osteogenesis of the implantation in vitro with composite fully deproteinized bone(CFDB) compounded by autologous red marrow.DESIGN: A randomized controlled study.SETTING: Department of Orthopaedics, the 152 Hospital of Jinan Military Area Command of Chinese PLA; Ward for Retired Cadres, First People's Hospital of Pingdingshan City; Department of Orthopaedics, Chaochuan Mine Hospital of Pingdingshan Coal Industrial Group.MATERIALS: The study was completed in the Department of Orthopaedics,the 152 Hospital of Jinan Militatry Area Command of Chinese PLA. Totally 40 Japanese flap-eared white rabbits of 4 months old of either gender with a body mass from 2.0 kg to 2.5 kg were involved (provided by the Laboratory for Experimental Animals of the 152 Hospital in Pingdingshan city).INTERVENTION: Calf CFDB scaffold materials were compounded by rabbit autologous red marrow after physical and chemical managements, which were then implanted into the thigh muscles of 40 rabbits. The osteogenetic abilities of the materials compounded by autologous red marrow were analyzed at 4 weeks and 8 weeks after operations respectively.ysis of the implanted bone.RESULTS: ALP activities were(63.48 ± 0. 873) and (69. 527 ± 0. 635) IU/L respectively, and the results of osteogenetic quantitative analysis were (2.50 ±0.38) and(4.70 ±0.67) points of rabbits in the study group at week 4 and week 8 respectively. ALP activities were(2.50±0.38) and (4.70 ± 0. 67) IU/L and the results of osteogenetic quantitative analysis were( 1.90 ± 0.54 ) and(3.40 ± 0.54) points of rabbits in the control group at week 4 and week 8 respectively. The results indicated that the osteogenetic ability of the study group was significantly higher than that of the control group at the same time point, and the neogenetic bone increased along with the prolongation of the implantation time.CONCLUSION: CFDB could be applied as scaffold materials for bone tissue engineering, and its osteogenesis increases significantly after being compounded by autologous red marrow.

Rat brain development is a complicated process.There are significant changes of histology, cytology and molecular biology in the process of fetal and postnatal brain development.The basic structure of brain has formed in the prenatal period.While the formation of connections between different parts and the improvement of the function of the brain occur after birth, during which many of the variations are bases of the nervous system diseases, so the postnatal brain development is still very important.Although the concept of brain microenvironment has been proposed more than 150 years ago, the research about the changing extracellular space ( ECS ) during the postnatal brain development has yet to gain significant progress.The author reviewed the anatomical and physiological characteristics of ECS in the process of postnatal development of the rat, stating the important role of ECS in the individual development, which is expected to provide reliable evidences for the explore of mechanisms and effective treatment approaches of pediatric development related nervous system diseases.

Objective To investigate the efficacy of transcutaneous injection of MIIGX3 artificial bone and methylprednisolone for recurrent bone cysts.Methods From January 2004 to March 2006,a total of 13 children with recurrent bone cysts received transcutaneous injection of methylprednisolone and MIIGX3 in our hospital.X-ray was employed to detect the degradation of MIIGX3 and formation of new bones.Results The operation time ranged from 30 to 95 minutes(mean 42 minutes).The patients were followed up for 1 to 3 years.None of them had recurrence of bone cysts during this period.The artificial bones were completely degraded and replaced by new bones in 1.5 years after the injection.Conclusions Transcutaneous injection of methylprednisolone and MIIGX3 is effective for recurrent bone cysts.Patients have shorter operation time and hospital stay after this treatment because the procedure is microinvasive.

Background Thyroid-associated ophthalmopathy (TAO) is a kind of clinically common and incurable ocular disease,and its incidence is at top place.The etiology and pathologic mechanism of TAO are still unknown because of shortness of replicative animal models and difficulty to acquire the ocular tissues in the early stage of the disease.To better understand the pathogenesis of TAO and investigate effective treatable measures, an appropriate animal model should be developed.Objective This study was to immunize female BALB/c mice with the recombinant plasmid of human thyroid-stimulating hormone receptor (TSHR) extracellular domain in cationic liposomes for the establishement of TAO models.Methods Thirty-two 6-to 8-week-old female BALB/c mice were randomly assigned to four groups according to computer random allocation.pcDNA3.1 +/hTSHR289 of 100 μg in an adjuvant cationic liposomes was injected via anterior tibialis muscle and peritoneal cavity separately in the recombinant plasmid injection group in 0, 3,6 weeks, and pcDNA3.1 or cationic liposomes was injected in the liposomes injection group or the blank plasmid group in the same way, respectively, and normal saline solution was injected in the blank control group.Body weight of the mice was measued before and 1 month,2,3 and 4 months after initial injection.The manifestations were observed after modeling.The mice were sacrificed 17 weeks after initial injection,and the histopathology examination was carried out on the thyroid gland and orbital tissue.The heart blood was collected from the mice,and serum contents of total thyroxin 4 (TT4) and thyroid-stimulating hormone (TSH)were assayed by ELISA.Results Protrusion, eyelid swell and keratitis occurred in 12 eyes of 6 mice in the recombinant plasmid injection group after immunization.A significant difference in the body weight of the mice was found among the blank control group, blank plasmid group, liposomes injection group and recombinant plasmid injection group (Fgroup =3.425, P =0.028), and the body weight was considerably reduced in the recombinant plasmid injection group in comparison with the blank control group, blank plasmid group,liposomes injection group (Ftime =0.838 ,P=0.023).The serum levels of TT4 were (7.75±1.00), (7.96±0.76), (6.76±1.10) and (4.43±2.88) μg/dlin the blank control group, liposomes injection group, blank plasmid group, and recombinant plasmid injection group, and those of TSH were (6.36±2.58),(4.83±3.96),(6.63±1.71) and (1.60 ±1.76) ng/ml, showing significant differences among the groups (F =7.150, P＜0.001;F =5.521, P＜0.01) , and the serum levels of TT4 and TSH were remarkably lower in the recombinant plasmid injection group than those of the blank control group,liposomes injection group and blank plasmid group (all at P ＜ 0.05).Histopathology revealed the lymphocyte infiltration of thyroid gland in 6 mice and proliferation of orbital adipose tissue, infiltration of lymphocytes and mastocytes,deposition of hyaluronic acid as well as swell, breakage and inflammatory cell infiltration of extraocular muscle in 15 eyes of the recombinant plasmid injection group.Conclusions A murine model of TAO can be successfully induced by immunization with recombination plasmid pcDNA3.1 +/hTSHR289 and cationic liposomes.The histopathology characteristics and ocular findings of the animal models are similar to human TAO.

Objective To evaluate the anatomic relationships between the portals and radial nerve of three different operations of antrolateral approach elbow arthroscopy.Methods The dissections were pedormed in 10 formalin soaked adult cadaver elbows.The distances from the three different antrolateral portals to the radial nerve in extension and flexion 90° position were measured.The portal A was located at 3 cm distal and 1 cm anterior to the lateral epicondyle;the portal B was located at 2 cm distal and 2 cm anterior to the lateral epicondyle;the portal C,1 cm distal and 1 cm anterior to the lateral epicondyle.Results The nearest distances from the anterolateral portal A,B,and C to the radial nerve in extension position were (2.30 ± 0.95) mm,(3.00 ± 1.56) mm,and (3.60 ± 1.65) mm,with significant differences (F =11.097,P =0.001).Statistical difference in distances from the anterolateral portal to the radial nerve between portal A and C was found (P =0.006).No statistically significant difference was seen between A and B or B and C (PA-B =0.134,PB-c =0.072).The distances from the anterolateral portal A,B,and C to the radial nerve in flexion 90° position were (4.40 ± 2.01) mm,(6.10 ± 1.79) mm,and (7.90 ± 1.85) mm,with significant differences (F =54.775,P =0.000).There were statistically significant difference among the three approaches (PA-B =0.000,PA-c =0.000,PB-c =0.002).The distances increased when the position changed from extension to flexion 90° for portal A (t =-5.161,P =0.001),portal B (t=-8.188,P=0.000),and portal C (t =-10.167,P =0.000).Conclusion The anterolateral portal 1 cm distal and 1 cm anterior to the lateral epicondyle is the safest apporach.

Objective:To explore the effect of phytic acid on apoptosis of SGC-7901 cells and its mechanisms. Method:The inhibiting action of phytic acid on SGC-7901 cells was examed by MTT assay,and the effect on apoptosis of SGC-7901 cells was examined by DNA gel electrophoresis,and the expressions of Fas,Bax and caspase-3 protein were detected by Western blot method. Results:From MTT assay,we observed that phytic acid inhibited the growth of SGC-7901 cells in dose and time dependent manner. Typical DNA ladder was found during gel eletrophoresis. Caspase-3 can be activated by phytic acid and the expressions of Bax and Fas protein in phytic acid group were higher compared with control group,and increased in a dose-dependent manner. Conclusion:Phytic acid can induce apoptosis of SGC-7901 cells which may be correlated to apoptosis associated protein Fas,Bax and caspase-3.

Objective To investigate the protective effects of pretreatment with valsartan, an angiotensin Ⅱ type 1 receptor blocker, on the brain against ischemia-reperfusion (I/R) injury. Methods Thirty-six healthy male C57BL/6J mice aged 10-12 weeks weighing 20-25 g were randomly divided into 2 groups (n - 18 each): valsartan group (V) and control group (C). In group V valsartan 2 mg?kg-1 dissolved in 2.5% NaHCO3 100 ?l was given intraperitoneally (i.p. ) every day for 10 days before experiment while in group C 2.5% NaHCO3 100?l without valsartan was given. The animals were anesthetized with intraperitoneal pentobarbital 40 mg?kg-1. Middle cerebral artery occlusion (MCAO) was produced by inserting an 8-0 nylon thread with rounded end into the left internal carotid artery and advancing it cranially until resistance was felt. MCAO was maintained for 1 h. The nylon thread was then withdrawn for reperfusion. A laser doppler blood flow detector (Omegaflo FLO-C1, Omegawave Co, Netherlands) was used to detect local cerebral blood flow (LCBF) at central and marginal infarct area [LCBF (%) = LCBF during I/R / baseline LCBF ? 100% ]. The model of MCAO was considered established when LCBF at central infarct area was 20% lower than the baseline value. LCBF was measured 10 min before MCAO (T0, baseline), as soon as MCA was occluded (T1) at 10, 30, 50 min of ischemia (T2-4) and at 10, 30, 60 min of reperfusion (T5-7) . MAP was measured immediately before valsartan administration, at T0 and T5. Neurological function deficit (NFD) was evaluated and scored (0 = no deficit, 4 = worst result) at 23 h after reperfusion was started . After evaluation of NFD the animals were anesthetized again and killed. The brains were removed. Cerebral water content was measured [cerebral water content (%) = (wet weight - dry weight) / wet weight ? 100%]. Infarct area was measured. Mortality rate was recorded.Results Pretreatment with valsartan did not affect MAP significantly but significantly reduced infarct area, brain water content, NFD and mortality rate and improved focal cerebral blood flow after MCAO. Conclusion Valsartan pretreatment can decrease cerebral infarct area induced by MCAO through improvement of focal cerebral blood flow after MCAO.
