Conclusion: This operation is a safe and an effective procedure for the treatment of the majority cases of cervical spondylotic myelopathy. In some cases this procedure should be done in combination with anterolateral decompression.

Salsola collina is widely distributed in droughty and semi-droughty area, which is used as a kind of folk remedy in traditional Chinese medicine for treatment of hypertension. The study is on the chemical constituents of this herb from its aerial parts to obtain its active constituents. Dried and crushed aerial parts of this herb were extracted three times with 95% EtOH at reflux. The ethanol extracts were combined and concentrated under reduced pressure at 70 ℃ to yield residue, which was suspended in water and successively partitioned with light petroleum, chloroform and n-butanol. The chloroform and n-butanol fractions were treated by various chromatographic techniques, such as silica gel, C18 reversed-phase silica gel and macroporous resin column chromatography. Compounds were elucidated by their physicochemical properties and spectroscopic analysis. In the course of our study on searching biological active components from this herb, a new alkaloid together with three known alkaloids were isolated and identified as N-transferuloyl-3-methyldopamine (1), 3-[4-(β-D-glucopyranosyloxy)-3- methoxyphenyl]-N-[2-(4-hydroxyl-3-methoxyphenyl)ethyl]-2-propenamide (2), salsoline A (3), salsoline B (4). Compound 4 is a new compound and named as salsoline B, while compound 2 was obtained in Salsola collina for the first time.

Objective To observe the clinical efficacy of Huoxue Rongluo Particles combined with acupuncture in the eight confluent points of spastic cerebral infarction paralysis and its effects on Glu and Asp levels of serum. Methods Totally 60 patients were divided into two groups: the experimental group and the control group. Both groups received basic Western medicine treatment, and the experimental group received Huoxue Rongluo Particles additionally, one dose a day for two times orally taken; Acupuncture was on eight confluent acupoint, every two days. 15 d is a treatment course, with 6 courses in total. Clinical spasticity index (CSI) and TCM symptom scores before treatment and the treatment of half month, 1 month, 3 months were observed. The levels of Glu and ASP in serum were detected, and TCM clinical efficacy was observed. Results The CSI score, levels of Glu and Asp in serum and TCM symptom scores of the patients after half-month, one-month, and three-month treatment were lower than those before treatment (P<0.05, P<0.01). There was no statistical significance in CSI score after half month treatment between the two groups (t=0.329, P=0.743). The CSI score in the experimental group after one-month and three-month treatment was lower than the control group (t=-2.636, P=0.024; t=-4.213, P=0.021). There was statistical significance in the levels of Glu and Asp between the two groups after half-month and one-month treatment (P<0.05, P<0.01). There was no statistical significance in the levels of Glu and Asp in the two groups after three-month treatment (P>0.05). The TCM symptom scores in experimental group was lower than the control group after half-month, one-month and three-month treatment (P<0.05). The total TCM effective rate was 86.67% (26/30) in experimental group, and 80.00% (24/30) in the control group, with the experimental group better than the control group (P<0.05). Conclusion Huoxue Rongluo Particles combined with acupuncture eight confluence acupoints in the treatment of spastic cerebral infarction paralyzed patients can relieve spasm degree, improve TCM clinical symptoms, which mechanism may be related to reducing serum excitatory neurotransmitters.

Objective Because of high incidence rate of complicated postoperative abdominal infections in abdominal injuries and difficulty in their clinical diagnosis and treatment,this article aimed to investigate the mechanism and the surgical tactics for this kind of complication.Methods Totally 48 abdominal-injured cases of postoperative complicated abdominal infections in our hospital from July 2005 to December 2010 were reviewed.These patients (Male 30,Female 18) aged 16-70 (mean 38) years.There were 20 cases of simple abdominal injuries,and 28 cases of multiple injuries ( ISS 16 - 52,mean 24.42).The complicated postoperative abdominal infections included abdominal incision infections (25cases),intra-abdominal infections( 18 cases) and retroperitoneal infections(5 cases).Forty cases were transferrted from other hospitals to our hospital 2 - 76 days after trauma.16 of which underwent exploratory laparotomy at other hospitals after injury,and 8 cases were directly transferred to our hospital after injury.Results All patients finally had a definite diagnosis by abdominal checking(26 cases),paracentesis(5 cases),ultrasound and CT scan ( 12 cases),and PET/CT scan (5 cases)in our hospital,and were confirmed by cultiure of pathogenic bacteria.The treatment included vacuum sealing drainage (VSD) (25 cases),percutaneous imaging- guided abdominal abscess drainage(13cases) and re-laparotomy ( 10 cases).Successfull treatment was achieved in 46 patients,death in 2 patients.The causes of death consisted of 1 case of severe craniocerebral injury,1 case of MODS.Conclusions Complicated abdominal infections often occurs after the operations of abdominal injuries.attentively abdominal checking,paracentesis,and CT scan repeatedly were proofs to benefit the finally diagnosis.VSD therapy is a simple and effective method for abdominal incision complication,and dynamic CT scan and prompt exploratory laparotomy can improve patients' prognosis.

Objective To analyze the clinical features and risk factors of isolated calf deep vein thrombosis (ICDVT).Methods Age,gender,locations,clinical symptoms,and risk factors of the hospitalized patients who diagnosed with ICDVT in the Department of Vascular Surgery,the First Affiliated Hospital of Zhengzhou University in 2015 were retrospectively analyzed.Results 122 hospitalized ICDVT patients were enrolled,accounting for 25.7％ of the patients with lower extremity deep vein thrombosis.Among them,41 cases (33.6％) were male,81 cases(66.4％) were female.The average age was 56.41 ±13.87 years.49 cases (40.0％) had left lower limb ICDVT,39 cases (32.0％) had right lower limb ICDVT;34 cases (28.0％) had both two lower limbs involved.Muscular calf vein thrombosis accounted for 77.9％ (95 cases).76 cases (62.3％) were painful.91 cases (74.6％) had swelling.Common risk factors included age (≥ 45 years) (85.2％),deficiency of natural anticoagulants (83.0％),surgery (45.9％) and malignant tumors (28.7％).Conclusions Pain and swelling were the main clinical symptoms of ICDVT.Age ≥ 45 years,deficiency of natural anticoagulants,surgery,and malignancy were main risk factors of ICDVT.

Objective To observe the influence of needling the Eight Confluent Points plus Huo Xue Rong Luo granules on the levels of gamma-aminobutyric acid (GABA) and glycine (Gly) in patients with spastic paralysis after cerebral infarction. Method Sixty patients with spastic paralysis after cerebral infarction were randomized into a treatment group and a control group, 3 0 cases each. The control group was intervened by basic treatment, while the treatment group was by Huo Xue Rong Luo granules plus acupuncture at the Eight Confluent Points in addition to the basic treatment, for 6 treatment courses in total. Before the treatment, and after half-a-month, 1-month, and 3-month treatments, the Chinese Stroke Scale (CSS) and activities of daily living (ADL) were evaluated, the levels of GABA and Gly were detected by using high performance liquid chromatography (HPLC), and the therapeutic efficacies were compared. Result After half-a-month treatment, the CSS score dropped significantly in both groups (P<0.01), and the between-group difference was statistically significant (P<0.01);the ADL score (Barthel Index score) increased markedly in both groups (P<0.01), and the between-group difference was statistically significant (P<0.01); the level of serum GABA increased significantly in both groups (P<0.05), and the between-group difference was statistically significant (P<0.05);the level of serum Gly rose up significantly in both groups (P<0.01), and the between-group difference was statistically significant (P<0.05). After 1-month treatment, the CSS score dropped significantly in both groups compared to that before treatment (P<0.01), and the inter-group difference was statistically significant (P<0.01);the ADL score increased significantly in both groups compared to that before treatment (P<0.01), and the inter-group difference was statistically significant (P<0.01);the levels of serum GABA and Gly increased markedly in both groups compared to that before treatment (P<0.01), and the inter-group differences were statistically significant (P<0.01). After 3-month treatment, the CSS score dropped significantly in both groups compared to that before treatment (P<0.01), and the inter-group difference was statistically significant (P<0.01);the ADL score increased significantly in both groups compared to that before treatment (P<0.01), and the inter-group difference was statistically significant (P<0.01); the levels of serum GABA and Gly increased markedly in both groups compared to that before treatment (P<0.05), approaching the normal levels, and the inter-group differences were statistically insignificant (P>0.05). Conclusion Needling the Eight Confluent Points plus Huo Xue Rong Luo granules is effective in treating spastic paralysis after cerebral infarction, which is plausibly associated with the up-regulation of inhibitory neurotransmitters (GABA and Gly).
