Objective To explore the clinical effect of Salvianolate for treatment of coagulant function abnormality in patients with septic shock.Methods One hundred and fifty-two septic shock patients admitted to Intensive Care Unit (ICU) of Department of Critical Care Medicine,Liuzhou Municipal Liutie Central Hospital from January 2007 to June 2016 were enrolled,and they were divided into a control group (67 cases) and a Salvianolate group (85 cases) by random number table.In the control group,conventional western medicine treatment was given,while in Salvianolate group,besides conventional treatment,additionally,Salvianolate 200 mg intravenous drip was applied daily for consecutive 10 days.The levels of D-dimer and platelet count (PLT) were examined on the 1st,3rd,7th,10th day after admission;disseminated intravascular coagulation (DIC) incidence and mortality were observed in 10 days after admission in the two groups.Results The levels of D-dimer were significantly lower in the Salvianolate group than those of the control group on 3,7,10 days after admission (mg/L:3 days was 9.14 ± 2.25 vs.18.42 ± 3.15,7 days was 6.71 ± 1.49 vs.14.57 ± 1.81,10 days was 1.01-± 0.20 vs.4.79-± 0.81,all P ＜ 0.01).In both groups,on the first day after admission the level of PLT began to decrease,on the 3th,7th day the levels were lowered significantly,and on the 10th day,the level of PLT was elevated;in the Salvianolate group,the levels of PLT were obviously higher on the 3rd,7th,10th day after admission than those of the control group [PLT (x 109/L) 3 days after admission:67.05-± 7.76 vs.40.97 ± 6.51,7 days:67.24 ± 6.35 vs.32.06 ± 5.13,10 days:90.18 ± 11.42 vs.59.04 ± 6.57,all P ＜0.01].The DIC incidence and mortality were significantly lower in the Salvianolate group than those of the control group [DIC incidence:12.94％ (11/85) vs.38.8％ (26/67),mortality:5.88％ (5/85) vs.29.85％ (20/67),both P ＜0.01].Conclusions Coagulant function abnormality was found in most patients with septic shock.The cause of PLT decreasing is mainly due to micro-vascular thrombosis that consumes a lot of PLT.Early intervention with Salvianolate in such patients can inhibit thrombosis,block the exhaustion of PLT and correct the coagulant function abnormality with certain efficacy in the patients.

Aim To study the effect of tubeimosides on human rectal cancer cell line SW480 in vitro and the mechanisms of its antitumor effect.Method The morphological changes were determined by means of light microscopy and electron microscopy respectively.Cell apoptosis was detected by flow cytometry through Annexin V assay and PI fluorescent staining methods.The protein levels of Bc1-2,p53 and Fas were determined using immunohistochemical technique.Results Apparent morphological characteristic of apoptosis was detected under the optical and electric microscope.The percentage of apoptotic cell increased when comparing the drug groups with control after treatment with tubeimoside Ⅰand Ⅲ.Immunohistochemical analysis revealed apoptosis was and induced by tubeimosides through inhibiting Bcl-2 and p53,and upregulating Fas.Conclusion Tubeimosides can induce apoptosis of SW480 cells,which may be one reasons of its antitumor effects.

Objective To explore the effect of sex difference on learning and memory function and the brain tissue damage of neonatal SD rats with hypoxic-ischemic brain damage.Methods Sixty,7-day-old neonatal Sprague-Dawley rats,were divided into randomly:male control group (M group,n=15),female control group (F group,n=15),male hypoxic-ischemic brain damage group (MHIBD group,n=15) and female hypoxic-ischemic brain damage group (FHIBD group,n=15).A modified newborn rat model that had a combined hypoxic-ischemic brain damage as described by Rice-Vannucci was used.The Morris water maze was used to evaluate the ability of learning and memory.The brain MRI and transmission electron microscope(TEM) was used to evaluate the scope of brain tissue damage and the change of the synaptic ultrastructure.Results There were no differences in swimming distance,escape latency,synaptic cleft and damage brain volume between M group and F group(P＞0.05).Compare with M group and F group,MHIBD group and FHIBD group showed significant brain injury,longer escape latency ((39.38±11.40) s vs (14.86±4.42) s,(30.14±7.18)s vs (18.41±5.03) s),longer swimming distance ((15.31± 1.77) cm vs (3.68±1.50) cm,(13.18±1.79) cm vs (4.61±1.61) cm),and TEM showed the synaptic cleft was widened ((23.18± 1.36) nm vs (19.24± 1.51) nm,(21.40± 1.71) nm vs (19.87±0.94) nm),P＜0.05).MHIBD group was more seriously compromised than the FHIBD group(P＜0.05).The brain MRI showed the damage brain volume of MHIBD group were significantly larger than FHIBD group(P＜0.05).Conclusion After bypoxic ischemic brain damage,the tolerance of brain damage and / or post-injury recovery capabilities of female rats are stronger than males.

ObjectiveTo evaluate the effect of electromyography biofeedback on motor function in children with spastic hemiplegia. Methods40 children with spastic hemiplegia were divided into control group (n=20) and treatment group (n=20). Both groups received comprehensive rehabilitation treatment. The treatment group received electromyography biofeedback in addition. They were assessed with Gross Motor Functional Measure (GMFM-88) in D and E items before and after treatment. ResultsThe scores of GMFM-88 in both D and E items were significantly different (P<0.01) before and after treatment in both groups, and significantly different between the treatment group and control group (P<0.05) after treatment. ConclusionElectromyography biofeedback can improve the motor capacity in children with spastic hemiplegia.

ObjectiveTo study the intelligence quotient(IQ) profile of the children with idiopathic generalized tonic-clonic seizure (GTCS) and the factors influencing IQ of them.MethodsAll 28 children with GTCS were selected who were aged 9 ～ 16 years in 20 GTCS families in a mountain area of the south of Anhui Province,all available healthy siblings of the children included in the epilepsy group,did not have epilepsy,and were nearest in age to the children with GTCS ( control group 1 ),and thirty children aged 9 ～ 16 years old who had lived in the same village ( control group 2) entered into our study.The IQ was studied of the three groups of children and the factors influencing IQ of children with GTCS at the same time.The data were input SPSS12.0 and analyzed.ResultsThe IQ of children with GTCS(85.64 ±20.57)was lower than that control group 1( 103.39 ± 11.17)and the control group 2 ( 106.17 ± 11.67).The difference between children with GTCS and the two control groups were significant for almost all the subtest quotients except completion of drawing and picture arrangement.No significant differences were found between the control group 1 and the control group 2 on the IQ and the subtest quotients.IQ scores of children with GTCS showed significant linear correlation with father's education( r=0.453,P＜0.01 ),age at onset of epilepsy( r=0.506,P＜0.01 ),duration of seizure disorder( r=-0.533,P＜0.0l ),status epilepticus( r=-0.732,P＜0.01),total number of seizures( r=-0.761,P＜0.01) and seizure frequency ( r=-0.708,P ＜ 0.01 ).ConclusionThe IQ scores of the children with idiopathic GTCS are lower significantly than general children population.Epilepsy-related variables affecting IQ scores of the children with idiopathic GTCS are duration of seizure disorder,status epilepticus,age at onset of epilepsy,total number of seizures,seizure frequency.

Objective: To investigate the impact of hypoxic-ischemic brain injury (HIBI) on brain development in neonatal rats of different sexes. Methods: From January 1 to December 31, 2018, 60 7-day-old SD rats were randomly divided into HIBI-F group (20 rats), HIBI-M group (20 rats), and control group (20 rats, 10 females and 10 males). The animal model of HIBI was established with Rice-Vannucci method, with the rats′ left common carotid artery double-ligated and severed. The rats were then placed in an incubator and exposed to a hypoxic gas mixture (8% O₂, 92% N₂) for 90 minutes. No intervention was given to the control group. Two weeks after HIBI, the motor development was evaluated by footprint analysis, the residual brain volume was measured by brain magnetic resonance imaging (MRI), and the damage of synaptic ultra structure was analyzed by transmission electron microscope. One-way ANOVA or χ² test was used for inter-group statistical analysis, and paired sample t test was used to compare the bilateral step length and toe distance of rats in the same group. Results: The mortality rate of HIBI-F was significantly higher than that of HIBI-M (20%(4/20) vs. 10%(2/20), χ²=40.000, P=0.001). The right step length and toe distance in HIBI-M group and HIBI-F group were significantly shorter than those in control group ((7.5±0.3) cm and (7.9±0.5) cm vs. (8.2±0.5) cm, F=9.605, P<0.01, (0.9±0.1) cm and (1.0±0.0) cm vs. (1.1±0.1) cm, F=71.437, P<0.01). Besides, according to above data, the right step length and toe distance in HIBI-M group were significantly shorter than those in the HIBI-F group (both P<0.01). Furthermore, the right step length was significantly shorter than the left step length ((8.3±0.4) and (8.3±0.5) cm, t=5.289 and 10.580, P=0.001 and 0.010, respectively) and toe distance ((1.1±0.1) and (1.1±0.1) cm, t=7.953 and 6.435, respectively, both P<0.01) in both HIBI-M group and HIBI-F group. Similarly, the synaptic gap of the left precentral gyrus neurons was longer in HIBI-M group and HIBI-F group than that in control group ((23.4±1.3) and (19.7±1.6) nm vs. (18.9±0.6) nm, F=71.719, P<0.01), and also longer in HIBI-M group than that in HIBI-F group (t=7.645, P<0.01). Likewise, the residual brain volume in HIBI-M group and HIBI-F group was significantly less than that in control group ((67±4)% and (75±5)% vs. 100%, F=406.122, P<0.01), and the residual brain volume in HIBI-M group was significantly less than that in HIBI-F group (t=-5.281, P<0.01). Conclusions Male neonatal rats are more vulnerable to HIBI and have severer subsequent brain injury and hemiplegia. Different treatment strategies for HIBI patients of different sexes should be developed.

Objective:To evaluate the viability and clinical effect of polyfoliate anterolateral thigh perforator flap (ALTPF) in reconstruction of large soft tissue defect around ankle.Methods:From June 2019 to October 2022, large soft tissue defects around ankle of 11 patients were reconstructed with ALTPF in the Department of Orthopaedics of the First Affiliated Hospital of Nanchang University. The causes of injury were traffic accident in 8 patients and heavy objects in 3 patients. All wounds were large defects (15.0 cm×14.0 cm-30.0 cm×20.0 cm) and combined with various degrees of infection. Intraoperatively, polyfoliate ALTPFs sized 16.0 cm×14.5 cm-23.0 cm×18.5 cm were used in reconstruction of the defects. Deep dead spaces were filled with antibiotic bone cement, and direct suture was performed to close the donor sites or by skin grafting repair. Postoperative follow-ups were scheduled at 1, 3 and 6 months, and 6 monthly thereafter at outpatient clinics and via telephone interviews. The appearance and colour of the flaps and healing of donor sites were recorded together with evaluation of the recovery of ankle motor function according to the ankle-hindfoot rating scale of American Orthopaedic Foot and Ankle Society (AOFAS).Results:All flaps survived. No haematoma or secondary infection occurred at the recipient site after surgery. All donor sites healed primarily. One patient had venous occlusion at the distal end of the polyfoliate ALTPF. The flap survived completely at 1 week after distal venous bloodletting. Postoperative follow-ups lasted 6-24 (15.27±5.21) months. All flaps had good blood supply with satisfactory appearance, similar colour and texture to the recipient sites, and without obvious bloat nor ulceration. Only a linear scar or few skin graft scar was left at the flap donor sites in concealed locations. The mean AOFAS ankle-hindfoot score was (88.36±10.21) point. There were 6 cases of excellent, 4 cases of good, and 1 case of fair.Conclusion:A polyfoliate ALTPF is an ideal flap for reconstruction of soft tissue defects around ankle by converting the length of a flap to the width.

OBJECTIVE: To evaluate the application of surgical strategies for the treatment of cervical ossification of the posterior longitudinal ligament (OPLL) involving the C ₂ segment. METHODS: The literature about the surgery for cervical OPLL involving C ₂ segment was reviewed, and the indications, advantages, and disadvantages of surgery were summarized. RESULTS: For cervical OPLL involving the C ₂ segments, laminectomy is suitable for patients with OPLL involving multiple segments, often combined with screw fixation, and has the advantages of adequate decompression and restoration of cervical curvature, with the disadvantages of loss of cervical fixed segmental mobility. Canal-expansive laminoplasty is suitable for patients with positive K-line and has the advantages of simple operation and preservation of cervical segmental mobility, and the disadvantages include progression of ossification, axial symptoms, and fracture of the portal axis. Dome-like laminoplasty is suitable for patients without kyphosis/cervical instability and with negative R-line, and can reduce the occurrence of axial symptoms, with the disadvantage of limited decompression. The Shelter technique is suitable for patients with single/double segments and canal encroachment >50% and allows for direct decompression, but is technically demanding and involves risk of dural tear and nerve injury. Double-dome laminoplasty is suitable for patients without kyphosis/cervical instability. Its advantages are the reduction of damage to the cervical semispinal muscles and attachment points and maintenance of cervical curvature, but there is progress in postoperative ossification. CONCLUSION OPLL involving the C ₂ segment is a complex subtype of cervical OPLL, which is mainly treated through posterior surgery. However, the degree of spinal cord floatation is limited, and with the progress of ossification, the long-term effectiveness is poor. More research is needed to address the etiology of OPLL and to establish a systematic treatment strategy for cervical OPLL involving the C ₂ segment.
