OBJECTIVE: To observe the clinical efficacy of nimodipine on cerebral infarction. METHODS: 120 patients with cerebral infarction were randomly selected into treatment group and control group(n=60). Both groups were given routine therapy, i.e. dehydration, neurotrophy, activating blood and dissolving stasis, lowering blood pressure, regulating blood lipid, lowering blood sugar and symptomatic treatment. Treatment group were additionally given oral dose of nimodipine 30 mg t.i.d. for 15 days. Clinical efficacies of 2 groups were observed and neurological impairment score before treatment and 15 days after treatment were evaluated. The change of hemorheology was detected by transcranial Doppler ultrasonography. RESULTS: The total effective rate of treatment group was 86.7%, which was significantly higher than that of control group(60.0%), there was significant difference between 2 groups(P

Objective To assess the clinical effects of Shenfu injection which consists mainly of panaxoside and water-solubility alkaloied on chronic pulmonary heart disease complicated with heart failure.Methods Ninetysix patients were randomly divided into two groups ,40 patients underwent regular treatment (control group) and 56 patients were treated with Shenfu injection additionally to regular treatment (treatment group ).There were 2 treatment durations,with 15 days in one duration.The symptoms,left ventricular ejection fraction (LVEF) and B type UNa peptide (BNP) were measured before and after treatment.Results The total effective rate in the treatment group was 91.1% (51/56) ,which was significantly higher than that in the control group (72.5% ,29/40) (P ＜0.05 ).After treatment,the treatment group has significantly higher LVEF than the control group(53.27% ±7.45%vs.49.12% ± 5.89% ) ( P ＜ 0.05 ),and significantly lower BNP ( ( 209.1 ± 18.7 ) ng/L vs.( 261.2 ± 19.3 ) ng/L ( P ＜ 0.05).Conclusions Shenfu injection could strengthen the contractility and increase LVEF,therefore improve the function of left ventricle,as well as decrease BNP and repair heart failure.

Objective To evaluate the clinical outcomes and report the second-look arthroscopic findings of reconstructed anterior cruciate ligament (ACL) using deep-frozen allograft.Methods Sixty-six patients undergoing ACL reconstruction using deep-frozen allograft in our institute with at least twelve months follow-up from January 2012 to March 2016 were included and received second-look arthroscopy.The patients consisted of 51 males and 15 females with an average age of 30.6 years (range,18 to 55 years) at the time of ACL reconstruction.Knee functions were evaluated by Lysholm score and International Knee Documentation Committee (IKDC) score.Knee stability was evaluated by drawer test,Lachman test and KT-1000 arthrometer.Second-look arthroscopic evaluation was performed in all patients,focused on continuity of the reconstructed ACL,the synovial coverage and subjective tension of the graft,and the prevalence of cyclops-like lesion and other changes after reconstruction procedures.Resuits All patients were followed up for average 18.3 months (range,12 to 36 months).Thirty-one patients underwent second-look arthroscopy from 12 to 18 months,and the other 35 patients underwent second-look arthroscopy from 18 to 36 months after ACL reconstruction.No infection,rejection reaction and other serious complication were reported after operation.The knee range of motion was normal in all cases,except that 10° extension limitation in one case.The Lysholm score significantly improved from preoperative 54.95±9.01 to 12 months postoperatively 86.14±5.86,and the IKDC improved from 54.79±9.12 to 85.11±5.77.Lachman test was positive in 8 cases,but negative in 58 cases postoperatively.KT-1000 arthrometer measurement showed that the side-toside difference significantly improved from preoperative 6.70± 1.24 mm to postoperative 1.52± 1.02 mm.Complete discontinuity occurred in 2 cases of the reconstructed grafts,graft tear in 4 cases.Cyclops-like mass was identified in 2 cases.The overall synovial coverage was slightly better in the patients who were followed up more than 18 months than those less than 18 months.However,there was no significant difference among the groups in the field of graft tension.The patients with taut grafts showed statistically better KT-1000 values (1.14±0.35 mm) than those with lax grafts (2.95±1.38 mm).Conclusion Frozen allograft could be a reasonable choice for ACL reconstruction.However,the graft integration and remodeling could tend to be slow.

Objective To evaluate the surgical treatment of the acute posterolateral complex(PLC)injuries of knee joint and then observe the clinical outcome.Methods Twelve cases(12 knees)of acute PLC injuries were treated from May 2006 to October 2008.Patients' age ranged from 23 to 47 years old,average 31 years.There were 9 males and 3 females.Rebuild the anterior cruciate ligament(ACL)and posterior cruciate ligament(PCL)under arthroscope and then,locally suture the PLC injuries sites on those patients with PLC avulsion fraction.If there is PLC rupture,then locally suture the injury sites plus PLC reconstruction.Knee functions were evaluated by IKDC and Lysholm score.Results All patients were followed up for 12-18 months(mean,13.3 months).The preoperative range of motion was 118.00°±6.77°,which was 130.75°±3.05° after surgery.KT-1000 arthrometer measurement showed that the average posterior translation improved from(14.85+1.83)mm preoperatively to(4.18±1.88)mm postoperatively.Seven cases were normal(A grade),3 cases were nearly normal(B grade),1 abnormal(C grade),and 1 severely abnormal(D grade)according to IKDC standard.The preoperative Lysholm joint function score was 35-44,average 38.83 ±3.16,which was 79-91,average 84.92±3.73 after surgery.Conclusion To those acute PLC injuries with avulsion at the ligament extremities,locally suture should be taken.But for those with PLC rupture at the mid part of ligament,locally suture the injury sites plus PLC reconstruction helps get satisfactory outcome.

Objective To study the clinical significance of the mRNA expression level of a novel gene which encodes a kind of transmembrane prostate protein induced by androgen-PMEPA1, as it may predict the progress of prostate cancer from hormone-dependent to hormone-independent. Methods We used Real-time PCR to detect the mRNA expression of PMEPA1 and GSTP1 in prostate cancer cell lines (LNCaP, PC-3), epithelia cells of benign prostatic hyperplasia and tissues from 33 patients with prostate cancers and 16 cases of prostatic hyperplasia. Results We found the mRNA expression of GSTP1 and PMEPA1 were both down-regulated in prostate cancer cell lines. The mRNA expression of GSTP1 was up-regulated in 6.1% of cases, down-regulated in 81.8%, and showed no difference in 12.1%. While PMEPA1 was highly expressed in 27.3% of cases, lowly expressed in 27.3%, and not differently expressed in 45.4%. Statistical analysis showed that the mRNA expression of GSTP1 was relevant to ages, but had no relationship with PSA, TNM stage, osseous metastasis or tumor differentiation, while the mRNA expression of PMEPA1 was relevant to osseous metastasis and tumor differentiation, but had no relationship with age, PSA or TNM stage. Conclusions PMEPA1 is possibly a useful biomarker, as it can identify patients with unfavourable prognosis, however, this hypothesis needs to be further studied with large samples.

Objective To compare the diagnostic efficacy and complications of transperineal prostate biopsy for<10 cores biopsy vs≥10 cores biopsy. Methods Nine hundred transrectal ul-trasound-guided transperineal prostate biopsies were performed. Patients were divided into 2 groups, <10 cores group and ≥10 cores group. Patient numbers of the 2 groups were 759 and 141, respec-tively. Cancer positive rate and complications were compared between the 2 groups retrospectively. Results Cancer positive rates were 41.6%(316/759) and 51.8%(73/141) in 2 groups (P<0.05). In patients of PSA≤10.0 ng/ml, cancer positive rates were 6.8% (16/235) and 17.8% (8/45) in 2 groups (P<0.05). Gross hematuria was the most common complication associated with biopsy. There was no statistical difference between the 2 groups in post-biopsy gross hematuria rate. Conclu-sions The diagnostic efficacy is higher in≥10 cores prostate biopsy than that in <10 cores prostate biopsy, There is no difference in biopsy related complications regarding biopsy core numbers.

Objective To discuss the effects of electroacupuncture intervention in different acupoints of rats models with diarrhea type irritable bowel syndrome (D-IBS).Methods The rat models were established with acute and chronic stimulation. The rats were divided into the normal control group, model group, “Taichong” (LR3) + “Zusanli” (ST36) group, and “Tianshu” (ST25) + “Zusanli” (ST36) group. Electroacupuncture was applied to bilateral corresponding acupoints for 20 minutes, every other day for 7 times. The physical signs of each rat were observed. The contents of 5-HT, NE and CGRP in the rats’ plasma were detected by sandwich ELISA. Results Compared with the normal group, the contents of 5-HT and NE in the model group were obviously higher and the content of CGRP decreased (P<0.05). Compared with the model group, the contents of 5-HT and NE in all treatment groups were lower and the content of CGRP increased (P<0.05). There was no difference between the “Taichong” (LR3) + “Zusanli” (ST36) and “Tianshu” (ST25) + “Zusanli” (ST36) groups.Conclusion The mechanism of electroacupuncture may be realized through lowering the contents of 5-HT and NE in the model rats and increasing the content of CGRP to treat D-IBS.

Objective To explore the safety and feasibility of calf arterial stent angioplasty to treat severe lower limb ischemia. Methods Clinical data of 13 patients in our hospital during recent 3 years were retrospectively analysed and all these patients were followed up after discharge.Of these patients there were 10 males and 3 females; mean age was (73 ±7) years; mean disease course was (8 ±4) months.Severe claudication was reported in 5 patients,rest pain in 4 patients,toe ulcer in 2 patients,gangrene in 2 patients.Stent was placed in the tibioperoneal trunk artery in 5 patients ; in the proximal part of peroneal artery in 3 patients; in the tibioperoneal trunk and proximal peroneal artery in 2 patients; in the anterior tibial artery in 2 patients; in the posterior tibial artery in one patient.Simultaneous endovascular treatment of femoral/popliteal arterial disease was done in 11 patients. Results All the procedures were successful and the treated arteries kept patent on discharge of patients.Claudication distance increased to be above 500 meter in 5 patients; rest pain relieved in 4 patients ; toes ulcer reduced in 2 patients,feet gangrene kept dry till discharge in 2 patients.Postoperative ABI increased in all patients.Patients were followed-up of mean (6.9 ± 2.2) months.One patient with previous toe gangrene underwent amputation due to recurrent pain while the stent in anterior tibial artery kept patent after 6 months discharge.In the other patient gangrene toe had fallen off and the wound healed.Two patients with toe ulcer had a total recovery and patients with previous rest pain had no recurrent symptoms. Conclusions Below knee arterial stent angioplasty is a safe and effective method in the treatment of severe lower limb ischemia.

ObjectiveTo analyze the surgical treatment of visceral artery aneurysm (VAAs).MethodClinical data of 19 patients surgically treated for visceral artery aneurysm in our hospital from Feb 2002 to Jun 2010 were reviewed. There were 7 cases of splenic, 1 of right hepatic, 1 of left gastric,3 of pancreaticoduodenal,2 of gastroduodenal, 1 of superior mesenteric, 1 of middle colic, 1 of left colic and 2 of renal artery aneurysms. Rupture of the aneurysm occurred in 12 patients. Transcatheter arterial embolization was performed in 13 cases, other 6 cases received open surgical treatment.ResultsFour patients suffered from recurrent bleeding after first embolization, 2 of those received surgery to stop bleeding, another 2 were successfully managed by second embolization.Bleeding were rapidly controlled in 8 ruptured patients associated with shock. Duodenum incomplete obstruction developed in 1 patient after pancreaticoduodenal artery embolization, another 2 patients suffered from partial splenic infarction after splenic artery operation. 18 cases were followed-up from 2 to 103 months without aneurysm recurrence.ConclusionsEndovascular embolization and open surgery for VAAs are safe and effective, endovascular intervention and embolization is especially life saving for ruptured pseudo-aneurysm cases.

Objective To investigate the effect and safety of autologons bone margow-mononuclear cell (BM-MNC)transplantation after the bone marrow stimulation in patients with thromboangiitis obliterans (TAO).Methods The bone marrows of 12 patients were stimulated by an injection of the recombinant human granuloeyte-macmphage colony-stimulatory factor(GCSF)for 3-5 days.150-200 ml bone marrow was drown from the iliac spine and the autologous BM-MNC were obtained in each patients.Fifteen lower limbs of 12 patients received implantation of the autologous BM-MNC by an intramuscular iniecdon.A series of subjective indexes(including improvement of pain and cold sensation)and objeetive indexes [including increase of ankle braehial index(ABI),transcutaneons oxygen pressure(TcPO2)and improvement of foot skin ulcer] were used to evaluate the effects.Results The outcomes were evaluated after 2 months of transplantation.The pain-relief rate and the cold feeling improvement rate were 86.7%(13/15)and 93.3%(14/15)respectively.The ABI were 0.38 ±0.05 vs.0.61 ±0.14(P<0.05)before transplantation and 2 months after transplantation respectively.increased in 66.7%(10/15)limbs.The TcPO2 of the ischemic legs increased from(27.47±2.85)mm Hg to(43.53 ±8.38)mm Hg(t=-7.03,P<0.05)after the transplantation,and the improvement rate of TcPO2 was 93.3%(14/15).Skin ulcers in improved in 8/9 limbs.Twelve patients were followed up for all average period of 10 months.The patients'symptoms improved in 80.0%(12/15)limbs,as to the objective index the ABI was0.57±0.13,TcPO2 was(42.07 ±7.81)mm Hg,which improved significandy compared to before treatment(t=-5.33,-7.80,Ps<0.05).skin ulcer healing rate was 66.7%(6/9).The ischemic symptoms in 2 patients were not relieved.There WBS no mortality and high level amputation in all subjects.The complications,such as proliferative retinopathy,malitpmnt tumor,myocardial infarction,stroke or hemangioma were not found in any patients.Conclusion In patients with TAO,intramuscular transplantation of autologous BM-MNC after the bone marrow stimulation has advantages of less bone marrow aspiration,more mononuclear cell content and relatively high safety.It may be a new and effective method to alleviate symptoms and accelerate the healing of skin ulcer.
