Objective To investigate the influence of Chinese medicine ( CM) treatment on life span of middle-late primary hepatic carcinoma (PHC) patients. Results A multicenter retrospective cohort study was carried out in 489 PHC patients at the stages of Ⅱb, Ⅲa and Ⅲb collected from 15 domestic hospitals. With CM treatment as the exposure factor, the enrolled patients were divided into CM group, western medicine (WM) group and the CM-WM combination group. The main outcomes included median survival time (MST) and survival rate, and the effects of CM treatment and minimally invasive therapy on MST were observed. Results Half-a-year survival rate, one-year survival rate and two-year survival rate were 50%, 9%, 1% in CM group, 70%, 30%, 6% in CM-WM combination group, and 50%, 10%, 0% in WM group, respectively. The survival rates in CM-WM combination group differed from those in CM group and WM group (P<0.01), but the differences of survival rates between CM group and WM group were insignificant (P>0.05) . MST at the stages of Ⅱb, Ⅲa, Ⅲb in CM-WM group was obviously prolonged as compared with the other two groups (P<0.01), and MST at the stages of Ⅲa, Ⅲb in CM group was also obviously prolonged as compared with WM group (P<0.05) . The difference of MST at the stage of Ⅱb was insignificant between CM group and WM group ( P>0.05) . CM treatment and minimally invasive therapy were effective on prolonging the survival time of PHC patients ( P<0.01) . The results of COX regressionanalysis showed that Karnofsky scores, CM treatment and minimally invasive therapy were the preventive factors for the prognosis. Conclusion CM-WM combination group has the best long -term therapeutic effect. CM -WM combination treatment is effective on increasing MST and long-term survival rate, in particular for PHC patients at the stages ofⅡb, Ⅲa and Ⅲb. CM treatment and minimally invasive therapy are helpful for the prolongation of the survival time of PHC patients.

ObjectiveTo evaluate the effects of exercise training on bone histomorphometry of ovariectomized rats.Methods46 SD rats were randomly divided into the normal control group (group A), ovariectomized group (group B) , estrogen supplement group (group C) and exercise training group (group D). The rats of group A had a sham operation, while that of other groups was ovariectomized. 3 months after operation, the rats had been treated for 3 months. The rats of group C were given estradiol, and the rats of group D were trained by exercise. The tibia sections were studied by histomorphometric analysis.ResultsThe values of the trabeclar area, trabeclar area%, trabeclar perimeter and trabeclar number of group D were significantly higher than that of group B. The values of the trabeclar separation, osteoclast number/mm2 and osteoclast number/mm of group D were the least in all groups, which had been ovariectomized. The values of the labeled perimeter % mineral apposition rate, bone formation rate of group D were superior to that of all groups.ConclusionThe exercise training can increase bone mass of ovariectomized rats, which had double effects of promoting bone formation and restraining bone absorption.

Objective To investigate the change of cardiac troponin Ⅰ (cTn Ⅰ),interleukin (IL)-6 in patients undergoing cardiac valve replacement and compare the degrees of fentanil,sufentanil,and remifentanil on myocardial protection and inhibiting effect of inflammatory.Methods Forty-eight patients,undergoing cardiac valve replacement,were randomly divided into three groups (n =16):remifentanil (group R),sufentanil (group S),and fentanil (group F).All the patients were total intravenous anesthesia of midazolam,opioid,vecuronim,and propofol.Different opioids were used in each group.Group R was induced with remifentanyl 1 ～2 μg/kg and maintained at a rate of 1 ～4 μg/(kg · min).Group S was induced with sufentanyl 1 ～2 μg/kg and maintained at a rate of 1 ～4 μg/(kg · h).Group F was induced with fentanyl 5 ～ 10 μg/kg and maintained at a rate of 10 ～30 μg/(kg · h).Blood samples were taken before anesthesia (T0),twenty minutes after aortic declamping (T1),the end of operation (T2),6 h (T3),and 24 h (T4) after cardiopulmonary bypass (CPB) for determination of plasma concentration of troponinⅠ and IL-6.Results Compared to T0,cTn Ⅰ and IL-6 in three group at T1,T2,T3 were significantly higher (P ＜ 0.05),cTn Ⅰ reached the peak level at T4 (P ＜ 0.05),IL-6 reached the peak level at T3 (P ＜ 0.05).Compared to group F,cTn Ⅰ and IL-6 in groups S and R at T1,T2,T3,and T4 decreased significantly (P ＜0.05).Conclusion Compared to fentanil,sufentanil and remifentanil had comparative advantages on lessening myocardial injury and inhibiting effect of inflammatory for patients who are undergoing cardiac valve replacement.

Objective To investigate the clinical effect of minimally invasive percutaneous repair of acute closed Achilles tendon ruptures with intraoperative ultrasound assistance.Methods A retrospective case series study was made on 24 patients with acute closed Achilles tendon ruptures hospitalized between January 2013 and June 2015.There were 19 males and five females,aged 18-50 years (mean,30.5 years).MRI showed total Achilles tendon ruptures,and time from injury to operation was 1-3 days.All patients underwent minimally invasive percutaneous repair with high-frequency ultrasound assistance.Operation time and either intraoperative or postoperative complications were documented.At last follow-up,American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and Arner Lindholm system were used to evaluate ankle functional recovery.Results Operation time was 35-60 minutes (mean,42 minutes).No intraoperative injury to the major vessel and nerve occurred.Follow-up was conducted for 10-18 months (mean,14.5 months).No surgery-related complications were detected,including wound infection,skin necrosis and tendon reruptures.Ankle function was recovered to normal.AOFAS score were improved from preoperative 53-74 points [(61.5-± 6.7)points] to 91-100 points [(97.1 ± 3.2) points] at last follow-up (P ＜ 0.05).According to the Amer Lindholm system,the treatment outcome was excellent in 21 patients and good in three,with the excellence rate of 100％.Conclusion Ultrasound-assisted minimally invasive percutaneous technique improves the quality of tendon anastomosis,avoids injury to the sural nerve,minimizes the incidence rate of complications such as re-rupture,wounds infections or skin necrosis and hence is an ideal method for repair of acute closed Achilles tendon ruptures.

Objective To determine the proper dosage of fentanyl for open heart surgery performed under cardiopulmonary bypass (CPB) without aortic cross-clamping and cardioplegia.Methods Twenty-seven ASA Ⅰ -H patients (10 male, 17 female) with fairly good cardiac function (NYHA Ⅰ - Ⅱ) scheduled for surgical repair of atrioseptal defect ( ASD) or ventricular septal defect (VSD) or mitral valve replacement (MVR) were studied. Age ranged from 18 to 44 years and body weight from 35 to 58 kg. The patients were randomly divided into three fentanyl dosage groups: group Ⅰ 10?kg ; group II 30 ?g kg-1 and group Ⅲ 50 ?g kg-1. Premedication consisted of intramuscular pethidine 1-2 mg kg-1 and scopolamine 0.05-0.06 mg kg-1 . Anesthesia was induced with midazolam 0.2 mg kg-1 and fentanyl 5 ?g kg-1 . Tracheal intubation was facilitated with vecuronium 0.15 mg g-1 . The patients were mechanically ventilated (Vr 8-10 ml kg-1 ,F 10-12 bpm,FiO2 100% ). The rest of the total dose of fentanyl (5 ?g kg-1 in group I , 25 ?g kg-1 in group II , 45 ?g kg-1 in group III) was infused after induction of anesthesia until the initiation of CPB, supplemented with inhalation of 0.6 % isoflurane. During CPB propofol was infused at 5 mg kg-1 h-1 . after discontinuation of CPB, again 0.6% isoflurane was inhaled until the end of surgery. Vecuronium 0.05 mg kg was given every 25-30 min during operation. EGG, HR, BP, CVP, SpO2, PET CO2 and body temperature (naso-pharyngeal and rectal) were continuously monitored during operation. Arterial blood samples were obtained before anesthesia (T0), 5 min after tracheal intubation (T, ) , immediately after thoracotomy (T2) , immediately before CPB (T3), 15 min after CPB was initiated (T4) , 10 min after termination of CPB (T5) and 5 min after chest was closed (T6) for blood gas analyses and determination of blood electrolytes and acid-base balance and blood concentrations of glucose, ACTH, angiotensin Ⅱ (A- Ⅱ ) and cortisol. Time of emergence from anesthesia and extubation were recorded.Results The demographic data, including age and body weight, CPB time and duration of surgery were comparable among the three groups. There were no significant changes in SpO2 , PETCO2 , body temperature, blood gases and electrolytes during operation in the three groups. MAP decreased significantly during CPB. The blood glucose, ACTH, A- Ⅱ and cortisol concentrations increased significantly during and after CPB as compared with the preanesthetic baseline (T0 ) ( P

To investigate the therapeutic effect and mechanism of Qingfei oral liquid in idiopathic pulmonary fibrosis. Seventy-two male SD rats were divided into control group, model group, pirofenidone group and Qingfei group with 18 animals in each group. The idiopathic pulmonary fibrosis was induced in last three groups by intratracheal injection of bleomycin; pirofenidone group was given oral administration of pirofenidone b.i.d for 21 d, and Qingfei group was given Qingfei oral liquid 3.6 mL/kg q.d for Lung tissues were obtained for HE staining, Masson staining and transforming growth factor (TGF)-β immunohistochemical staining. Superoxide dismutase (SOD), malondialdehyde (MDA) and glutathione (GSH) were detected in tissue homogenates. The BATMAN-TCM database was used to retrieve the chemical components and their corresponding targets of Qingfei oral solution by network pharmacology method, and then the component-target-disease network diagram was constructed. Finally, the pathway enrichment analysis was carried out to explore the molecular mechanism of Qingfei oral liquid against idiopathic fibrosis. Histopathology results showed that Qingfei oral liquid had a similar relieving effect on pulmonary fibrosis as the positive drug pirfenidone; TGF-β secretion had a significant reduction in lung tissues of Qingfei group; and Qingfei oral liquid had better regulatory effect on SOD, MDA and GSH than pirfenidone. The results of component-target-disease network and pathway enrichment analysis showed that the related molecular pathways were concentrated in inflammation, extracellular matrix and cytokines. Qingfei oral liquid has a good therapeutic effect on idiopathic pulmonary fibrosis in rats via regulation of inflammation, extracellular matrix and cytokines.

OBJECTIVE:To shorten the turnover days of hospital drug inventory,reduce the cost of drug inventory and improve the level of hospital drug inventory management.METHODS:The data of 65 kinds of antitumor drugs and its adjuvant drugs during Jan.1st,2016-Dec.31st,2016 were collected from hospital information system (HIS) of our hospital,such as price,inventory to classify by using ABC classification method.According to demanded quantity of class A drugs in the secondary drug storage,the amount purchased of upper and lower limitation of class A drugs could be calculated.The data of class C drugs were analyzed one by one to determine the "temporary use" drug directory.The turnover days of class A drugs and the inventory cost of class C drugs were counted before and after classification management.RESULTS:There were 10 class A drugs,accounting for 15.38％ of total types and 78.27％ of total consumption sum;the turnover days of pharmacy inventory decreased from (43.96 ± 19.04) d to (13.64 ± 8.02) d by adopting the principle of purchasing in small quantity by several times.There were 10 "temporary use" drugs of class C drugs,accounting for 26.32％ of total types,270 thousand yuan inventory cost saved each year.CONCLUSIONS:Hierarchical management of hospital drug inventory by ABC classification can effectively optimize the inventory types and amount,and provide definite evidence for "temporary use" drugs so as to shorten turnover days of pharmacy inventory and recue the cost of pharmacy inventory.

Objective To compare the efficacy and safety of tranexamic acid(TA)and norethisterone(NET)for the treatment of patients with ovulatory menorrhagia in China. Methods Onehundred and thirty one patients with proven ovulatory menorrhagia from gynecologic clinics of 5 teaching hospitals located in 4 different cities in China were enrolled during Jul 2004 to Dec 2006.Ameng them 128 completed the study.Patients were randomly divided into two therapeutic regimen groups:TA 1g thrice daily during menstrual cycle days(D)1-5,69 cases;or NET 5 mg twice daily on D19-26.59 cases.The drugs were administered for 2 consecutive cycles,then withdrawn and patients were followed-up for 1 more cycle.Data on menstrual blood loss [ estimated by pictorial blood assessment chart(PBAC)],length of menstrual periods,quality of life(QOL)evaluated by a 6 item health-related questionnaire were collectedbefore,during each cycle and were compared.Results Both treatments led to significant decreases of mean PBAC scores and shorter duration of menstrual periods,and improved the QOL ranking during the twotreatment cycles.The mean percentages of PBAC decrements in the TA first and second cycles were significantly greater than those in the NET corresponding cycles(35%VS 17%,P=0.004;4J4%VS 34%,P=0.04 respectively).The success rate of TA second cycle was higher than that of the NET second cycle (41%VS 24%,P=0.04).Improvement of QOL ranking in the TA first cycle was also significantly better than those in the NET first cycle ( P=0.03).The percentage of patients with at least 1 adverse event in TA group(19%)was significantly lower than that in NET group(35%,P=0.04).Patients'willingness tocontinue the treatment in the TA second and follow-up cycles(94%,79%respectively)were significantly higher than those in the corresponding cycles of NET groups(79%,59%respectively;P=0.01,P=0.02).Conclusion The regimen of TA 3 g daily during menstrual days 1-5 is a more effective and tolerable treatment than luteal phase norethisterone for patients with ovulatory menorrhagia.

OBJECTIVETo explore the role of peroxisome proliferator-activated receptor γ (PPARγ) signaling pathway in osteo- blast differentiation of rat bone marrow mesenchymal stem cells (BMSCs) cultured in simulated microgravity.

METHODSRat BMSCs were cultured in simulated microgravity (by rotating clinostat) in the presence of 10 µmol/L pioglitazone, 10 µmol/L GW9662, or both pioglitazone and GW9662, with the cells cultured in normal gravity as the control group. After osteogenic induction for 14 days, the cells were stained with alizarin red for the bone nodules and with oil red-O for the fat cells, and the fat rate was calculated. ALP activity in the cells was determined in each group, and RT-PCR was performed to detect cellular expressions of PPARγ mRNA.

RESULTSPioglitazone significantly inhibited osteoblast differentiation of the BMSCs, whereas GW9662 promoted the cell differentiation by suppressing the activation of PPARγ.

CONCLUSIONWe hypothesize that the activation of PPARγ signaling pathway is one of the main mechanisms for inhibited osteoblast differentiation of rat BMSCs in simulated microgravity, and inhibiting PPARγ pathway activation can effectively prevent and treat microgravity-induced osteoporosis.
