[Objective] To evaluate the curative effect of anterior cruciate ligament(ACL)reconstruction for remaining anteromedial or posterolateral bundle and ruptured fiber.[Method]Among 89 cases of ACL rupture,there were 32 cases of sports injury,24 cases training injury,23 cases traffic accidents and 10 cases sprained in daily life.ACL ruptured at the notch of the femur in 24 cases,and at the intercondyle of the tibial in 28 cases.Thirty-two cases were reconstructed with quadri-bundle Hamstring tendon knot press-fit technique and 20 cases were reconstructed with quadriceps tendon press-fit technique with autogenetic patellar bone.ACL anteromedial bundle(AMB)ruptured in 14 cases and posterolateral bundle(PLB)ruptured in 23 cases.The intact bundle and the remnants of ACL were preserved.AMB and PLB were reconstructed with double-bundle Hamstring tendon knot press-fit technique in 37 cases.Absorbable interference screws were used at the tibial tunnel and sutured tendon was knotted across the tibial bone bridge.[Result]The average duration of follow-up were 25 months(14-37 months).Lysholm knee function score increased by 27.7 scores,from average 67.5 scores of pre-operation to average 95.2 scores at the end of the follow-up.Rulermetr examination tibial translation was 4 mm?2 mm in 72 cases and 6 mm?3 mm in 17 cases.Lachman test was negative in 79 case,weakly positive in 8 cases and positive in 2 cases.The function of the knees were improved and the stabilization was strengthened after operation.According to knee therapeutic effect evaluation criterion,76 cases were excellent and 13 cases were good.[Conclusion]To keep the remaining of anteromedial or posterolateral bundle and ruptured fiber for ACL reconstruction is beneficial for the graft revascularization or healing,and is helpful for the position sense or rehabilitation.

[Objective]To explore the effects of extracorporeal shock waves(ESW) therapy on tendon-bone healing after reconstruction of the anterior cruciate ligament(ACL).[Method]Animal model of reconstruction of the anterior cruciate ligament in 18 healthy F/M New Zealand white rabbits(2～3 months old) were established using digital long extensor tendon and randomly classified into 2 groups.The ESW group was given extracorporeal shock waves therapy on 24 hours after reconstruction of the anterior cruciate ligament while the control group with only reconstruction of the anterior cruciate ligament but no more therapy.All animals were sacrificed at 2、4、8 weeks after operation for histological examinations.The specimens were stained with hematoxylin-eosin and Masson trichrome to investigate pathology change of the tendon-bone healing tissue.The ink intravascular injection was used to observe the neo-vascularization of tendon-bone healing tissue.[Result]The histological examination revealed that at 4 weeks after operation,the ESW group,tendon-bone interface was filled with proliferated fibroblasts and chondroblasts,the collagen fibers were obviously increased and regularly arranged.At 8 weeks after operation,the healing tissue at the bone-tendon interface had developed into dense connective tissue,the collagen fibers were formed in abundance and the perpendicular collagen fibers were regularly and longitudinally arranged.The transition zones of collagen fibers,fibrocartilage and bone(the structure alike a direct ligamentous insertion) occurred in the local region of tendon-bone interface.The histological observations showed that the tissue healing at tendon-bone interface of the ESW group were quicker than those of the control group.The proportion of neo-vessels at the tendon-bone interface of the ESW group were significantly higher than those of the control group at 4 and 8 weeks after operation(respectively P=0.028,P=0.008).[Conclusion]Extracorporeal shock wave treatment can significantly improve the tendon-bone early healing after reconstruction of the anterior cruciate ligament in rabbits.

Objective To evaluate the effect of mild hypothermia on acute cerebrovascular diseases. Methods Sixty-two cases of severe cerebrovascular diseases were randomized into hypothermia group and control group. In hypothermia group the patients were cooled to 34～35℃ for 48h ,while the patients in the control group treated by routine methods. Median nerve short latency somatosensory evoked potentials (SLSEP) and brain-stem auditory evoked potentials (BAEP) were recorded before cooling and 30 minutes, 24, 72, and 120 hours after cooling. The changes of EP were analyzed statistically. Results After treatment with mild hypothermia, the N13-N20 interpeak latency (IPL) of SLSEP and I-V IPL of BAEP were significantly reduced as compared with those of the control group ( P

OBJECTIVE:To investigate the effects and safety of Xingnaojing injection combined with butylphthalide on neuro-logical function,cognitive function,coagulation function and living activity. METHODS:A total of 106 patients with middle cere-bral artery infarction in Wuhan University People's Hospital during Jun. 2014-Dec. 2015 were divided into control group and obser-vation group according to random number table,with 53 cases in each group. Besides routine symptomatic treatment,control group was given Butylphthalide soft capsules 0.2 g,po,tid. Observation group was additionally given Xingnaojing injection 20 mL added into 0.9% Sodium chloride injection 250 mL,ivgtt,qd. Both groups were treated for 14 d. The neurological function score (NI-HSS,NFDS),cognitive function score (MoCA,MMSE),coagulation function indexes (PT,APTT,FIB),BI score were ob-served in 2 groups before and after treatment. The occurrence of secondary remote damage and ADR were recorded. RESULTS:Eight patients withdrew from the study,including 3 patients of control group and 5 of observation group. Before treatment,there was no statistical significance in neurological function scores(NIHSS,NFDS),cognitive function scores(MoCA,MMSE),coag-ulation function indexes or BI scores between 2 groups (P>0.05). After treatment,NIHSS,NFDS scores and FIB of 2 groups were decreased significantly compared to before treatment,and the observation group was significantly lower than the control group,with statistical significance (P<0.05). MoCA,MMSE,BI scores in 2 groups were increased significantly,and PT and APTT in 2 groups were prolonged significantly,and the observation group was significantly higher or longer than the control group, with statistical significance (P<0.05). The incidence of secondary remote damage in observation group (11.3%) was significantly lower than control group (41.5%),with statistical significance (P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:For middle cerebral artery infarction,the application of Xingnaojing injection combined with butylphthalide can reduce the risk of remote damage,promote the recovery of neurological function and cognitive func-tion,and improve coagulation function and living activity with good safety.

We investigated the effects of γ-interferon and exogenous indole on the growth of domestic dominant standard strains and clinical straìns of Chlamydia trachomatis E-UW-5/Cx,and compared with the dominant strains of D-UW-5/Cx abroad.We used DMEM-10,DMEM-10 containing 5 ng/mL recombinant human interferon gamma (referred to as DMEM-10+IFN) and DMEM-10 containing 5 ng/mL recombinant human interferon gamma and 50 μM exogenous indole (referred to as DMEM-10+IFN+IND) to culture C.trachomatis,and then we fixed it with methanol to count inclusions after 48 hours,observing the influence of r-interferon and exogenous indole on the growth of C.trachomatis standard strains(E,D) and clinical strains.Results showed that the count of Chlamydia inclusion bodies in DMEM-10+IFN group was significantly lower than others (P＜0.05);no significant difference was found (P＞0.05) between the count of DMEM-10 group between DMEM-10+IFN+IND group.There were no significant difference between the E and D standard or clinical strains (P＞0.05).Under the effect of IFN-γ,the growth of domestic dominant strain E-UW-5/Cx C.trachomatis was significantly inhibited.After adding exogenous indole,C.trachomatis can escape the scavenging activity of IFN-γγto restore the infection vitality.

ObjectiveTo analyze the association of HLA-DQA1 gene polymorphism with persistent Chlamydia trachomatis genital infection.Methods Blood samples were collected from 80 patients with persistent genital Chlamydial infection,80 patients with common genital Chlamydial infection(who tested negative for Chlamydia trachomatis after one course of standard systemic treatment) and 80 normal human controls.HLA-DQA1 alleles were genotyped by PCR followed by gene sequencing.ResultsThe frequency of HLA-DQA1*0102 allele and HLA-DQA1*0501 allele was 22.5％ and 5.0％ respectively in patients with persistent genital Chlamydial infection,5％ and 20％ respectively in those with common genital Chlamydial infection,2.5％ and 17.5％ respectively in normal human controls.Compared with the patients with common genital Chlamydial infection and controls,the patients with persistent genital Chlamydial infection had a higher frequency of HLA-DQA1*0102(x2 =14.6286,P ＜ 0.001 ),but a lower frequency of DQA1*0501 (x2 =6.2598,P ＜ 0.05).ConclusionsHLA-DQA1*0102 allele may be a susceptible gene or closely linked with the susceptible genes of persistent genital Chlamydial infection.HLA-DQA1*0501 allele may have protective effects against persistent genital Chlamydial infection.

Objective To investigate the effects of mobility training on mobility and the mRNA levels of both synaptophysin and growth associated protein 43 (GAP-43) in the region around an infarction in rats with acute cerebral infarction. Methods Models of cerebral infarction were created in 100 rats through middle cerebral artery occlusion. They were then randomly divided into training and control groups. The motor skill of the rats was examined using a beam walking test. The mRNA levels of both synaptophysin and GAP-43 in the region around the infarction were observed at the 1st, 3rd, 7th, 14th and 28th days after model-creation using a semi-quantitive reverse transcrip-tion polymerase chain reaction. Results The rats' mobility scores increased with training, and significant differ-ences were observed between the average scores of the two groups at the 3rd, 7th and 14th days. The scores were higher in the training group. The mRNA levels of both synaptophysin and GAP-43 in the region around the infarction increased significantly from the 1st to the 3rd and 7th days. Synaptophysin mRNA levels were significantly higher in the trained group at each time point, but the levels of GAP-43 mRNA were significantly higher in the trained group only on the 3rd and 7th days. Conclusions Motor skill and the mRNA levels of synaptophysin and GAP-43 in the region around an infarction can be increased by motor skill training, at least in rats with model acute cerebral infarc-tion.
