Objective To observe the clinical treatment of severe acute left heart failures with non-invasive mask ventilator. Methods All patients were conducted on common treatment of heart failure, including high concentration oxygen,tranquillizer,cardiac stimulant,diuretic,vasodilators and antispasmodic and asthma,etc. ,and mechanical ventilation with non-invasive mask ventilator is emergently applied to the patients whose state of illness could not be controlled. Results 35 cases were mitigated and the success rate up to 77.8% ;there were remarkable differences in pH values of arterial blood, PaO2, PaCO2, SaO2 and vital signs before and after ventilators were applied (P ＜ 0. 05). Conclusion The non-invasive mask ventilator was an effective measure for treatment of severe acute left heart failure.

Objective:To observe the clinical efficacy and side effects of highly agglutinative staphylococcin injection at high dose combined with oxaliplatin or cisplatin with intraperitoneal perfusion in the treatment of malignant peritoneal effusion. Methods:Totally 60 patients with malignant peritoneal effusion were divided into two groups,32 cases in group A,and 28 cases in group B. Group A was treated with staphylococcin at high dose combined with oxaliplatin with intraperitoneal infusion after peritoneal cavity catheter drainage,and group B was treated with staphylococcin at high dose combined with cisplatin with intraperitoneal infusion after peritoneal cavity catheter drainage. All patients underwent the treatment once a week,and continuous four weeks for a courese. The clinical efficacy and adverse drug reactions were compared between the two groups. Results:The complete response rate of group A was 18. 8% ,and the total effective rate was 90. 7% ,which were both significantly higher than those of group B(P < 0. 05). The incidence of abdominal pain in group A was higher than that in group B(P < 0. 05),while there were no significant differences in the total incidence of adverse drug reactions and the other symptoms between the two groups(P > 0. 05). Conclusion:Staphylococcin at high dose combined with oxaliplatin with intraperitoneal perfusion is more effective than staphylococcin at high dose combined with cisplatin. Although abdominal pain in group A is obvious,the patients are able to tolerate with it after the symptomatic treatment,therefore,staphylococcin at high dose combined with oxaliplatin with intraperitoneal perfusion can be used as one of effective methods for the treatment of malignant peritoneal effusion.

Objective To evaluate the effects of different durations of severe acute hypervolemic hemodilution (AHH) on acute lung injury in rabbits.Methods Thirty-six healthy adult rabbits of both sexes, weighing 2.7-3.1 kg, were randomly divided into 2 groups (n=18 each) using a random number table: control group (C group) and AHH group.AHH was performed with 6％ hydroxyethyl starch 130/0.4 until the target hematocrit of 20％ was achieved in group AHH.Immediately before AHH (T0) , and at 1,2 and 4 h after AHH (T1-3) , blood samples were taken from the right femoral artery for blood gas analysis.The oxygenation index was calculated.The occurrence of acute lung injury (oxygenation index ≤ 300 mm-Hg) was recorded.After blood samples were collected at T1-3 , 6 rabbits in each group were sacrificed, and lungs were removed for determination of wet/dry lung weight ratio (W/D ratio) and aquaporin-1 (AQP-1) expression (by immuno-histochemistry).Results In group AHH, 1 rabbit developed acute lung injury at 1-2 h after AHH, and 4 rabbits developed acute lung injury at 2-4 h after AHH.Compared with group C,W/D ratio was significantly increased at T1-3, and the expression of AQP-1 was down-regulated at T2,3 in group AHH (P＜0.05 or 0.01).Conclusion Severe AHH performed with 6％ hydroxyethyl starch 130/ 0.4 with the target hematocrit reduced to 20％ and the duration ＞ 1 h induces acute lung injury in rabbits.

Objective To investigate the feasibility and safety of minimally invasive pereutaneous nephro-lithotomy(MPCNL) in treating impacted upper ureteral calculi. Methods 50 cases with impacted upper ureteral cal-culi treted with MPCNL were analyzed retrospectively. Results All cases were rendered stone free at one session, clearance rate was 100%, 1 case required transfusion,no other major complications was observed. Conclusion MPC-NL was safe and effective in treating impacted upper ureteral calculi with a high clearance rate.

Objective To evaluate the efficacy and toxicity of docetaxel combined with Cisplatin(DDP) and 5-fluorouracil(5-Fu) in the treatment of advanced gastric cancer. Methods 35 patients with advanced gastric cancer,which were confirmed by pathological diagnosis,were treated with docetaxel + DDP +5-Fu regimen:docetaxel 70 mg/m2 iv infusion for 4 hours on day 1, DDP 20 mg/m2 iv infusion on day 1 to 5,5-Fu 750 mg/m2 iv infusion for 6 hours on day 1 to 5 every 3 ～ 4weeks. Patients responsing to the chemotherapy finished at least 4 ～ 6 cycles or proceeded the therapy until progression of the disease (PD). Results 32 cases (91.4% ) were available for response evaluation with CR0;PR 15;SD7;PD 10. The rate of total remission( CR + PR) was 46.9% (15/32) ,and rates of CR and SD were 0 and 21.9% respectively. Leucopenia was seen in 40% patients,in which 13.6% cases were in grade III -IV. One patient had fever with neutropenia and improved after active treatment. There was no systemic infection or therapy-related death in all patients. Conclusion Docetaxel + DDP +5-Fu regimen has an assured response for advanced gastric cancer with tolerable toxicity and could be an effective candidate in clinical treatment.

Objective To explore the efficacy and safety of transcatheter intra-arterial hyperthermo-chemotherapy for advanced ovarian carcinoma. Methods 36 patients with unresectable or recurred ovarian carcinoma were divided into two groups randomly: treatment group(n=20) and control group(n=16). Transcatheter intra-arterial infusion warmed to 62 degree chemo-agents via the ovarian tumor supplied artery was performed in the treatment group while routine intraarterial chemotherapy was done in the control group. The CA125 level dynamic change, short-term efficacy and side effect after the interventional procedure were compared between two groups.Results The CA125 level decreased significantly in the treatment group more than that in the control group(?

Objective To measure the leakage rate in the process of expansion in vivo and in normal saline and the over-expansion property of the expander.Methods We chose 17 cases that were treated with the skin expansion.We recorded total injected saline volume intentionally in these cases before the second surgery,and recorded the remainder of the volume of saline postoperatively.We injected normal saline into 8 expanders,respectively,exceeding 50％ of the volume-rating;and subsequently put these expanders into plastic bucket filled with saline.30 days after,we measured the remaining volume of the normal saline.We injected 100 ml normal saline into 4 expanders,respectively,of which nominal volume was 100 ml,and then left these expanders in saline and measured the remainder volume of the saline 30 days later.In the second time,we injected 150 ml and repeated the abovementioned process.It was repeated 7 times until the injection volume reached 400 ml.We processed the data and depicted a curve of effective expansion.Results The results showed that the leakage rate reached (29.0+12.5) ％ in vivo.Experiments in vitro confirmed that 85.0％ (8.0/9.4) of the saline leaked through the injection port and 14.8％ (1.4/9.4) leaked through the membrane of the expander.In addition,over-expansion performance index test confirmed that the over-expansion property of an expander was about twice the nominal volume.Conclusions The expander is not completely sealed structure.Normal saline can leak through the injection part and the membrane of the expander.The over-expansion property of an expander is limited.When the volume injected into the expander exceeds a certain value,the effective expansion performance is not increased with it.

Objective To analyze the differences of video laryngoscope, direct laryngoscopy and fibreoptic bron﹣choscope nasal intubation on hemodynamics, inflammatory and stress response. Methods 117 patients underwent surgery from November 2013 to March 2015 were chose as research subjects and randomly divided into video laryn﹣goscope group, direct laryngoscopy group, fiberoptic bronchoscope group based on different cannula enrolled way. Then compared the hemodynamics, inflammation, stress level after intubation among the three groups. Results Com﹣pared with the T0, the three groups patients' systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), C-reactive protein (CRP), interleukin -6 (IL-6), tumor necrosis factor (TNF-α), norepinephrine (NE), plasma cortisol (Cor), angiotensinⅡ(ATⅡ) differences had no significant difference (P>0.05);compared with direct laryn﹣goscopy group, video laryngoscope group, fiberoptic bronchoscope group patients' T1, T2, T3 SBP, DBP, HR, CRP, TNF-α, IL-6, NE, Cor, ATⅡ levels were lower; compared with the video laryngoscope group, optical fiber bron﹣choscopy group patients SBP, DBP, HR, CRP, TNF-α, IL-6, NE, Cor, ATⅡ low levels at T1, T2, T3 were lower (P<0.05). Conclusions Fibreoptic bronchoscope nasal intubation has less influence on patients, will not cause severe stress and inflammatory response, it is one of the ideal instrument anesthesia induction intubation.

Objective To investigate the effect of tissue expansion in facial congenital giant nevus.Methods From October 2014 to October 2016,7 cases of facial congenital giant nevus patients were treated with expanded skin flaps,including single expansion and secondary expansion.Partial excision and skin tissue expansion were used to drastically remove giant pigmented nevi on body or extremities of infants.There were some points for attention during the surgery:the size and location of the partial excision and expander should be designed reasonably;no tumor-manipulation and non-tension principle should be taken great notice,and expanders should be linked up with one another when several expanders were used at the same time,so as to reduce the possibility of forming the envelop,which was favorable for the second surgery of transfer of a skin flap.Results All cases of giant pigmented nevi excision were on the face,which were completely removed from the patients.The areas of the nevi were from 7 cm × 5 cm to 15 cm × 13 cm.All patients were followed up for 3-12 months (mean 6 months).All flaps survived well.Expander exposure was happened in 2 cases with no bad results.One case of scar received late repair due to surgical scars and all got satisfactory results.Conclusions Tissue expansion is an ideal method in the treatment of facial congenital giant nevus.
