BACKGROUND: Anterior cervical discectomy combined with cage and anterior locking titanium plate is widely used for the treatment of various kinds of cervical spondylosis. Microsurgical technique has increasingly become a standard technique.OBJECTIVE:To explore the clinical effects of anterior cervical microsurgical discectomy combined with cage and anterior locking titanium plate for cervical spondylosis. METHODS: Clinical data of 108 patients treated with anterior cervical microsurgical discectomy combined with cage and anterior locking titanium plate were retrospectively analyzed. According to the clinical outcome before and after surgery,including the scores of Japanese Orthopedic Association, visual analogue scale of neck and upper extremities, neck disability index, imaging manifestations (disc space height and Cobb angle) and other indexes, the surgical results were evaluated.RESULTS AND CONCLUSION: Compared with pre-operation, the postoperative Japanese Orthopedic Association score, visual analogue scale score of neck and upper extremities, neck disability index score, disc space height and Cobb angle were markedly improved, with a significant difference (P < 0.05). The improvement-rate of the spinal function included 102 excellent cases and 6 good cases. Complete fusion of bone graft observed in all cases. It suggested that anterior cervical microsurgical discectomy combined with cage and anterior locking titanium plate has significant effect on various types of cervical spondylosis.

Objective To investigate the effect of acupuncture at the primary points of the three yin meridians of the foot on blood pressure in an animal model of high/low blood pressure and explore the specific effect of the meridian points-the primary points of the three yin meridians of the foot.Methods The study included the parts of hypertension and hypotenstion. Both parts were allocated to the primary points of the three yin meridians of the foot, non-acupoint, model and blank groups, six rats each. Except the model and blank groups, all the groups were given acupuncture treatment for seven consecutive days. Blood pressure was measured after the completion of treatment. Five consecutive measurements were made in each rat. Mean values of blood pressure were taken.Results For the part of hypertension, blood pressure at each time point was higher in the acupuncture groups than in the blank control group and lower than in the model group, and there were statistically significant differences (P<0.05), indicating that acupuncture at the primary points of the three yin meridians of the foot has a hypotensive effect. The hypotensive effects of Taichong and Taixi were better than those of Taibai and the non-acupoint (P<0.05). The hypotensive effects of Taichong and Taixi were equal (P>0.05). The hypotensive effect of Taibai was equal to that of the non-acupoint (P>0.05). For the part of hypotension, blood pressure at each time point was lower in the acupuncture groups than in the blank control group and higher than in the model group, and there were statistically significant differences (P<0.05), indicating that acupuncture at the primary points of the three yin meridians of the foot has a pressor effect. The pressor effect was worse in the the non-acupoint group than in the primary points of the three yin meridians of the foot group (P<0.05). The pressor effects of Taibai and Taixi were equal but worse than that of Taichong (P<0.05).Conclusions Acupuncture at the primary points of the three yin meridians of the foot has a specific bidirectional regulating effect on blood pressure. Of them, point Taichong produces a best bidirectional regulating effect on blood pressure.

Objective To investigate the clinical effect of edaravone on free radical damage after acute stroke. Methods The 60 patients with acute stroke were randomly divided into therapy group and control group. Both the groups were treated with routine approaches of dehydration, intracranial pressure reducing and blood pressure control. The treatment with balanced saline 250 ml plus edaravone 30 mg, intravenously infusion twice a day, was adopted in therapy group, while the control group received balanced saline 250 ml only, the treatment lasted for 14 days. Before and 14 days after treatment, the neurologic impairment analysis, activity of daily living scale (ADL) and serum superoxide dismutase (SOD) were checked. Results Compared with control group, after 14 dtreatment, the improvements in neurologic impairment analysis (7.5±5.4 vs. 15.9±7.9, P＜0.05),ADL (58.32±11.57 vs. 43.73± 12.48, P＜0.05) and SOD[(157.25±21.81)mmol/L vs. (127.08 ± 13. 14)mmol/L, P＜0. 05] occurred in therapy group. Conclusions Edaravone could increase the ability of cleaning free radicals and promoting function of nerves recovery.

Objective To analyze the new breeding of eggplant "HANGQIE-5"(HQ-5) generated by space mutagenesis with RAPD,identify the differential RAPD bands,and try to provide molecular proofs for space mutation breeding.Methods Dry seeds of two eggplants "Tianshuichangqie(TSCQ)" and Longguoyuanqie(LGYQ) were carried by "shenzhou-4" and "shenzhou-3"spaceship.Two mutant lines "TSCQ-MUT-4" and "LGYQ-MUT-4" were selected after four generations of self-cross of TSCQ and LGYQ.A new variety of "HQ-5" was selected by crossing the two lines of "TSCQ-MUT-4" and "LGYQ-MUT-4",which were male and female,respectively.The RAPD reaction system was optimized with orthogonal design and further RAPD analysis was applied.Results The RAPD reaction system was determined as follows: DNA: 40 ng,dNTPs: 7.5 nmol,primer: 10 ng,and rTaq polymerase: 1.25 U.The RAPD results displayed that TSCQ-MUT-4 produced four differential bands compared with its wild type,while LGYQ-MUT-4 produced one,through space flight.Six differential fragments were amplified between HQ-5 and the paternal/maternal.HQ-5 not only shared the common fragments with its parents,but also held some particular ones,which were stably inherited.Conclusion The results indicate that space mutagenesis could cause mutations in DNA of plants,and is helpful to generate a new breeding.

BACKGROUND:Nasolabial fold flap has been widely used in clinical surgery. The facial artery anatomy has been widely used in clinical research. Angular artery dissection is becoming more and more important to nasolabial groove area surgery, but at present, there is a lack of anatomical analysis of internal angular artery.
OBJECTIVE:To study the anatomy of the angular artery, and to provide anatomical data for protecting the nasolabial flap during surgery.
METHODS:Twenty sides of adult cadaver specimens on head and face were dissected. A reference coordinate system was made based on the line between the connection of two medial angles of eyes (axis X) and the facial midline line (axis Y). The location of the angular artery was measured taking A-F as reference points.
RESULTS AND CONCLUSION:(1) The slant angles of the angular artery on BC section, CD section, DE section and EF section were (11.1±4.3)°, (34.1±8.8)°, (21.5±10.5)°, and (17.0±4.7)°, respectively. (2) The angular artery sourced from facial artery was more than it sourced from ophthalmic artery. The diameter of right blood vessel was larger than that of left side. (3) The angular artery sourced from ophthalmic artery comes from the location which extended 8.1 mm to both sides from the point which was 10 mm up from the intersection of facial medial angle of eyes connection and midline. The blood vessel diameter of the starting point was (0.7±0.2) mm. The whole range was 20.1 mm. (4) The angular artery sourced from facial artery comes from the location which extended 25.8 mm to both sides from the point which was 40 mm down to the intersection of facial medial angle of eyes connection and midline. The blood vessel diameter of the starting point was (0.9±0.3) mm. Point to the wing of nose the lateral distance was (5.0±1.2) mm. The whole range was 68.7 mm. The surface projecting of angular artery coming from research results provided anatomic basis for surgery of nasolabial flap.

Objective To observe the risk factors for portal vein thrombosis (PVT) in cirrhotic patients prior to receiving endoscopic treatment to prevent gastroesophageal varices rebleeding.Methods A retrospective analysis was conducted on cirrhotic patients admitted to Zhongshan Hospital,Fudan University from 2008 to 2013 for secondary prevention of gastroesophageal varices bleeding via endoscopic treatment.Relevant information and data were collected,followed by an univariate analysis and multiple Logistic regression analysis in attempt to identify potential factors affecting the formation of PVT.Results Totally 591 patients were enrolled in the present study and were classified as present-PVT group (n =122,20.64 ％) and absent-PVT group (n =469,79.36 ％).Univariate analysis showed that MELD score,hemoglobin,platelet count,total bilirubin,alanine aminotransferase,blood urea nitrogen,splenectomy ratio all achieved statistical significance between the two groups (P＜0.05).The multiple Logistic regression showed that MELD score,lowered blood urea nitrogen,elevated D-dimer and history of splenectomy were independent factors associated with the formation of PVT (P values were separately 0.016,0.026,0.014 and ＜0.001).Conclusions Cirrhotic patients should receive regular surveillance for MELD score,liver function,D-dimer and portal vein ultrasonography,especially in patients received with a previous history of splenectomy.

Objective To explore the effect of early phase rehabilitation training on the urination function recovery of the patients with paraplegia caused by spinal cord injury (SCI).Methods Sixty-six patients with paraplegia caused by SCI were selected and divided into the rehabilitation and the control group.The rehabilitation group of patients received early phase rehabilitation training on the urination function,the control group received routine training on the urination training and urinary catheter nursing care.The urination function recovery effect was compared between two groups.Results The urination function recovery effect of the rehabilitation group was significantly better than the control group.Conclusions The usage of early phases of urination training measures on the SCI paraplegia patients can help them cast off the catheter,build up regular urination,and reduce complications.

Objective To study the relationship between advanced liver fibrosis and peripheral neuropathy in patients with type 2 diabetes mellitus (DPN). Methods A total of 173 patients (89 men and 84 women) with type 2 diabetes who hos?pitalized in Tianjin Third Central Hospital within nearly three years (2013.02-2015.02) were divided into three groups ac?cording to non-alcoholic fatty liver disease (NAFLD) fibrosis score:group A (NFS≤-1.455), group B (-1.455

Objective:To evaluate the clinical significance of expression of proliferation cell nuclear antigen(PCNA),P16 and P27genes in adenoid cystic carcinoma of salivary glands.Methods:The expressions of PCNA,P16and P27were detected by immunohistochemical staining (SP)in 55 patients with adenoid cystic carcinoma of salivary glands.Results:The higher and lower expressions of PCNA were 45.5%(19/55) and 65.5%(35/55) respectively;of P16 were 45.5%(25/55) and 54.5%(30/55)respectively.And the positive and negative expressions of P27 were 34.5%(19/55) and 65.5%(36/55),respectively.The correlation of expression of PCNA gene with local recurrence and tumor site showed significant (P=0.0317,P=0.0186);but the expression of P16was no any significant correlation in all of the variables.The expression of P27 was significant on the regional lymph node metastaisis (P=0.0083).When higher expression of P16was 45.5%(25/55),the P27positive expression was 56.0%(14/25),which showed a significant positive correlation (P=0.0025).Conclusion:In adenoid cystic carcinoma of salivary glands,the PCNA gene should be one of the biological target predicting local recurrence,and P27gene should be one of the biological target justifying regional lymph node metastasis.

Objective To investigate the relationship between plasma soluble CD36 (sCD36) and nonalcoholic fatty liver disease (NAFLD) in patients combined with type 2 diabetes mellitus (T2DM). Methods Plasma levels of sCD36 were determined in normal control group (group A, n=39), patients of T2DM without NAFLD group (group B, n=39) and T2DM with NAFLD group (group C, n=59). Liver fat content (LFC) and nonalcoholic fatty liver fibrosis score (NFS) were calculated in group C. Glucose and lipid metabolic parameters, liver function parameters and inflammatory parameters were also detect?ed in all three groups. Variance analysis was applied to analyze the differences of the above parameters among three groups;Correlation analysis was used to analyze the relationship between sCD36 level and all the above parameters;Multiple step? wise regression analysis was applied to determine the influencing factors of sCD36 level in patients of group C. Results Plasma sCD36 (μg/L) levels in group B (3.87 ± 1.16) and group C (5.72 ± 1.79) are higher than that of group A (2.57 ± 0.93) (both P<0.01), and it is higher in group C than in group B (each P<0.05);Correlation analysis showed that sCD36 level was positively correlated with body mass index (BMI), waist, visceral adipose tissue,fast insulin (FINS), insulin resistance in?dex (HOMA-IR), free fatty acid (FFA), alanine transaminase (ALT), tumor necrosis factor-α(TNF-α), interleukin-6 (IL-6), LFC and NFS (P<0.01 or P<0.05);Multiple stepwise regression analysis showed that FFA, LFC, TNF-αand IL-6 were in?fluencing factors of sCD36 level in patients of group C. Conclusion Plasma sCD36 level was related to fatty liver severity, liver injury and fatty liver fibrosis, it might be used as a plasma marker of T2DM combined with NAFLD. CD36 might con?tribute to the development of T2DM combined with NAFLD through inflammatory mechanisms.
