Objective To investigate the clinical efficacy and safety evaluation of fibrinolytic,anticoagulant and antiplatelet drug combination treatment in patients with progressive ischemic stroke (PIS). Methods Ninety cases with PIS were randomly divided into the treatment group (47 cases) and the control group (43 cases). The patients in the control group were given combination therapy of Diemailing, Nadroparin calcium and Ozagrel,while the combination therapy of Defibrase, Diemailing, Nadroparin Calcium and Ozagrel were given in the treatment group. The plasma fibrinogen (Fib), prothrombin time (PT), part enabled prothrombin time (APTT), liver and kidney function were observed. The clinical efficacy was evaluated after 14 days treatment. Results After treatment,the total effective rate of the treatment group was 89.4% ,which was significantly higher than that of the control group (67.4%) (P ＜ 0.05). After treatment, the PT and APTT levels of the treatment group were respectively (19.76± 5.53)s and (35.43 ± 6.03)s,the control group were respectively(17.26 ± 1.49)s and (35.71±5.64) s, the PT and APTT increased significantly compared with the pre-treatment condition in both groups (P ＜ 0.05), while the difference between the two groups was not statistically significant (P ＞ 0.05). The Fib level was (1.51 ±0.42)g/L in the treatment group,and (3.10 ±0.69)g/L in the control group. In the treatment group the Fib level was significantly lower than the control group and the condition before treatment(P ＜0.05). We found no significant difference between conditions before or after the treatment in the control group (P ＞ 0.05). The incidence of adverse clinical events showed no significantly difference between the treatment group and control (P ＞0.05). Conclusions Applying of fibrinolytic, anticoagulant and antiplatelet drug combination treatment in patients with PIS has a good efficacy and safety,which is good for clinical application.

[Objective]To explore the "acute angle" of femur,and evaluate the bone tunnel technique in posterior cruciate ligament reconstruction.[Method]Using the porcine flexor digitorum tendon as graft,the author reconstructed posterior cruciate ligament.The bone tunnel was established with the angle of 80?,90?and 100?comparison the tunnel and intercondylar fossa of femur side wall,and press sensitive film was set between the edge of tunnel and graft.The pressure between was used to represent abrasion.The bigger the pressure was,the larger the abrasion was.The difference of pressure between bone tunnel technique group and the control group was compared.[Result]The pressure of angle 100?was lowest(3.55?0.21 MPa).And the pressure of burnishing group(3.29?0.19 MPa)was lower than that of the control group(3.55?0.21 MPa).[Conclusion]The bone tunnel technique can reduce the femoral;"acute angle" of femur in posterior cruciate ligament reconstruction.

Objective To evaluate the effect of one step flexible ureteroscopic lithotripsy for incarcerated upper ureteral calculi.Methods The clinical data of 80 cases of incarcerated upper ureteral calculi were retrospectively analyzed between August 2015 and September 2016.Theone step flexible ureteroscopic lithotripsy was used in 40 cases (one step group),including 22 male cases and 18 female cases.The average age was (40.0 ± 9.5) years.The maximal stone diameter was (i.8 ± 0.5) cm.The widest width of the ureter above the stone was (2.5 ± 1.1) cm.The CT value of stone was (1 089.0 ± 111.3) HU.Two step method was used in 40 cases (two step group),including 21 male cases and 19 female cases.The average age was (41.0 ± 10.7).The maximal stone diameter was (1.7 ± 0.6)cm.The widest width of the ureter above the stone was (2.3 ± 0.9) cm.The CT value of stone was (1 002.0 ± 97.2) HU.During the one step flexible ureteroscopic lithotripsy,only flexible ureteroscope was used to crush the stone,no matter whether the stone located in the ureter or return to the renal pelvis.During two stepmethod,the rigid ureteroscopy was firstly used for crushing the stone in the ureter.When the stone return to the renal pelvis,the rigid ureteroscopy was change into flexible ureteroscope for continuous crushing the stone.Compared two groups' operating time,2 weeks stone clearance rate and the cases of fever after operation.Results The mean operative time in the one step group was (37.45 ± 11.34) min.The mean operative time in the two step group was (55.07 ± 13.57) min.The difference was statistically significant (P ＜ 0.05).The number of infection 2 cases in one step group and 9 cases in two step group.The difference was statistically significant (P ＜ 0.05).2 weeks stone clearance rate was 87.5％ (35/40) in one step group and 82.5％ (33/40)in two step group.There was no significant difference between two groups.Conclusions Flexible ureteroscope one step method is a safe and effective alternation for incarcerated upper ureteral calculi.

Objective To systematically evaluate the optimal indwelling time of double?J stent in the treatment of ureteral complicated calculi post?ureteroscopy. Methods A total of 161 patients with complicated ureteral calculi were enrolled in this study from August 2012 to August 2015. All patients received the treatment of ureteroscopic holmium YAG Laser lithotripsy and were randomly divided into 3 groups according to varied double?J stent indwelling time: group A < 2 weeks (n = 43),group B from 2 ~ 6 weeks(n = 67),and group C>6 weeks (n = 51). Complications of three groups were compared and the hydronephrosis after removing double?J stent was recorded. Results The rate of complications of group C was significantly higher than that in group A and group B (P<0.017). However,group A(10/43)has a higher rate of ureterostenosis after removing double?J stent compared with group B(4/67)and group C(3/51),while no statistical significance was observed between group B and group C. Conclusion The incidence of complications after lithotripsy increased with the indwelling time of double?J stent,but the short indwelling time would led to ureterostenosis. Therefore,the optimal indwelling time of double?J stent after flexible ureteroscopy was 2 to 6 weeks,and the indwelling time for patients with injury ureteral mucosa could be appropriately prolonged.

Objective To observe the curative effect of external physical vibration lithecbole (EPVL) therapy after extracorporeal shock-wave lithotripsy (ESWL) in upper urinary calculi.Methods A total of 133 patients of upper urinary calculi with randomly divided into 2 groups after ESWL therapy during the period of 2012 October to 2013 February.The EPVL group (66 cases) used the physical vibration lithecbole treatment,and the natural lithecbole group (67 cases) used the method by drinking water,adding exercise and other natural lithecbole method.Of the EPVL group,6 of the stones were located in the upper or middle calyx,13 in renal pelvis,16 in lower renal calyx and 31 in ureter,the stone diameter was 10-15 mm.Of the natural lithecbole group,8 of the stones were located in the upper or middle calyx,17 in renal pelvis,15 in lower renal calyx and 27 in ureter,the stone diameter was 10-15 mm.The clinical data of the curative effect,side-effect,and complications were collected and analyzed systematically.Results In the EPVL group,the average times of lithagogue treatment was 2.6 times,51 patients (77％) expelled stones on the day of lithecbole,and the stone free rate in a week was 79％ (52/66).Especially,81％ (13/16) of the lower renal calyx expelled stones on the day of lithecbole,and the stone free rate in a week was 88％ (14/16).Whereas,30 patients (45％) in the natural lithecbole group expelled stones on the day of ESWL,and the stone free rate in a week was 49％ (33/67) ; the lower renal calyx stone expulsion rate on the day of ESWL was 33％ (5/15),and the stone free rate in a week was 40％ (6/15).The curative effects were significantly different between the 2 groups (P＜ 0.05).There were no serious complications in both groups.Conclusions EPVL machine can significantly promote the stone expulsion after ESWL.Compared with traditional methods,EPVL therapy has a better curative effect,especially on lower renal calyx stones.EPVL is a safe and noninvasive treatment.

Vagus nerve reflex is a rare complication of percutaneous renal decompression. It is often induced by excessively rapid decompression of severe hydronephrosis and traction of the main nerves innervating the kidney. The clinical manifestations are irritability, sweating, clammy skin, hiccups, slow heart rate. It is easy to misdiagnose. In this study, 4 patients with vagus nerve excitement after percutaneous renal decompression were treated. After monitoring the patient’s vital signs and giving treatment such as expanding blood volume and raising blood pressure, the symptoms gradually disappeared.

By means of literature review, this paper summarized fire hazard features of hospital ward buildings. Case study plus overseas literature enabled the authors to come to recommendations based on personnel layout and evacuation speed in hospital ward buildings. Then Pathfinder was used to simulate personnel evacuation in a hospital ward building, and to calculate the safe evacuation time needed in such conditions as normal state, blocked or locked safe exits. These calculations help present suggestions on fire safety management.

Objective To investigate the clinical value of limited debridement in treating diabetic foot osteomyelitis with incomplete foot gangrene.Methods Retrospective analysis of traditional surgery (complete removal of diseased bone and soft tissue) and limited debridement (limited removal of diseased bone and soft tissue) in patients with incomplete foot gangrenuria foot osteomyelitis from February 2015 to March 2017,There were 38 cases in the traditional operation group and 76 cases in the limited debridement group.Between the two groups,the sex ratio (20/18 vs 41/35),age (64.90±8.40 vs 68.1±8.10),Wagner 3/4 grading ratio (12/26 vs 26/50),the ratio of nerve ulcers/ischemic neurotic ulcers (13/25 vs 24/52),the ulceration ratio of forefoot/middle foot±hind foot (33/5 vs 68/8),arterial ABI (0.71±0.39 vs 0.67±0.33),and lower extremity arterioplasty ratio (52.63％ vs 59.21％),combined with hypertension (78.95％ vs 77.63％),coronary heart disease (71.05％ vs 69.74％),cardiac insufficiency (10.53％ vs 9.21％),renal failure rate (21.05％ vs 22.37％),incidence of hypoproteinemia (10.53％ vs 10.53％),anaemia (15.79％ vs 19.74％) and drug resistance of drug resistant bacteria (26.32 vs 23.68％) had no statistical difference.All the patients received antibiotic after surgery.The incidence of antibiotic related complications,the rate of amputation on the ankle,the average length of hospitalization,the average healing time of the ulcer/wound,the rate of readmission in one year,the rate of recurrent ulcer,the rate of new ulceration,the rate of ulceration and the death rate were collected to evaluate the clinical effects.Results The duration of antibiotic use in the traditional operation group (25.2±12.3 d) and the average hospitalization time (16.9±7.6 d).The average healing time of ulcer/wound (121.6 ±23.7 d) was shorter than that of limited debridement group (32.5± 16.8 d,24.7± 12.5 d,153.2±27.8 d).The amputation rate (1.32％),re-admission rate (1.32％),ulcer recurrence rate (2.63％) and ulcer recurrence rate (1.32％) in the limited debridement group were significantly lower than those in the traditional operation group (10.53％,31.58％,21.05％,28.95％).There was no significant difference in the incidence of antibiotic-related complications and all-cause mortality between the two groups.Conclusion Conservative surgery for diabetic foot osteomyelitis of incomplete foot gangrene is scientific and reasonable,and the quality of life of patients can be improved.The clinical benefit is obvious.It is worth of clinical promotion.
