Objective To investigate the effect of corpectomy decompression by subtotal vertebrectomy and fusion of adjacent segmental artificial disc replacement through anterior intervertenral spance (Hybrid Surgery) in the anteriorcervical spondylotic myelopathy treatment . Methods Hybrid Surgery were operated on 18 patients who suffered from anterior cervi?cal spondylotic myelopathy . Follow up of 1-50 months. Patient’s conditions were assessed according to the Japanese Associ?ation for Department of orthopedics assessment score (JOA score) before and after operation. Effects of Hybrid operation were assessed by the improvement of JOA score, Odom’s follow-up grade and cervical mobility . Results The JOA scores of all 18 operated patients were improved from 10.6 ± 1.7 before operation to 13.5 ± 2.4 after operation. And the difference is statistically significant (t=1.314, P < 0.05). Among all the operated patients, 16 were cured and 2 were effective. As to Odom’s follow up grades, 6 cases were excellent, 11 cases were good and 1 case was acceptable. The postoperative move?ment range of cervical spine (40.1° ± 8.4°) show no statistically difference compared with that in preoperation (42.6° ± 11.9°) (t=0.68, P > 0.05). Conclusion Hybrid Surgery of anterior cervical decompression and fusion can both improve the nerve function and preserve cervical mobility.

Objective To explore the clinical value of imaging examinations of medullary sponge kidney with the literature reviewed.Methods The features of X-ray plain film (1 case),IVP (2 cases),B-mode US(3 cases) and CT images (9 cases) of medullary sponge kidney (MSK) in 11 cases were analysed retrospectively.Results X-ray plain film showed a cluster of round and oval high density images in renal papillae and renal medulla in one case one kidney.Collecting tubes were showed as like line,brush and sac like dilatation on IVP in 2 cases 3 kidneys.B-mode US revealed a cluster of high echo spots scattered in renal medulla in 3 cases 5 kidneys and sac like dilatation of collecting tubes in 2 cases 3 kidneys.CT images showed the stones of spongiform kidney scattered alone renal medulla in 9 cases 16 kidneys,while the stones covered by contrast media on enhanced CT images in 3 cases 5 kidneys,and enhanced stripes of high density projected from renal papillae to renal medulla.Conclusion X-ray plain film,IVP,B-made US and CT all can be used in diagnosing spongiform kidney.Plain film and IVP are yet the first selected methods and IVP is specific and direct in showing collecting tubes dilatation.B-mode US especially CT have a high showing rate of stone in spongiform kidney and can be helpful to evaluate the collecting tube dilatation.

· AIM: To investigate the influence of TGF-β 2 antisense oligonucleotide(ASON) on the differentiation, proliferation of stromal fibroblast in corneal stroma injury.both eyes of 28 rabbits, the right eyes were served as experimental group, corneal incisions were sutured with 8-0 coated vicryl suture carrying TGF-β 2 ASON; the left eyes were served as control group, corneal incision were sutured with common 8-0 coated vicryl suture. Rabbits were killed at 4, 7, 14 and 28d after surgery, stromal fibroblasts were examined by immune histochemistry and electron microscopy.significantly reduced the numbers of cells expressingα -smooth muscle actin (α -SMA) and proliferating cell nuclear antigen (PCNA). The ultrastructure of fibroblast had no significant difference in two groups.differentiation and proliferation of stromal fibroblast in corneal injury. This will be a new method to adjust corneal wound repair.

Objective To investigate the effect of perioperative pulmonary infection in elderly patients with mild to moderate chronic obstructive pulmonary disease (COPD) undergoing general anesthesia.Methods Forty elderly patients undergoing general anesthesia and abdominal surgery, 24 males, 16 females, aged 65-81 years, ASA physical status Ⅰ-Ⅲ, BMI 19-28 kg/m2, were randomly divided into two groups (n=20 each): protective ventilation group (group PV) and conventional ventilation group (group CV).Lung protective ventilation was received in group PV: intermittent positive pressure ventilation, tidal volume 6 ml/kg (ideal body weight), positive end expiratory pressure (PEEP) 5-10 cm H2O, alveolar recruitment maneuver every 30 minutes;conventional ventilation was received in group CV: intermittent positive pressure ventilation, tidal volume 10 ml/kg (ideal body weight), without using the PEEP and alveolar recruitment maneuver.Venous blood samples for interleukin 6 (IL-6) and interleukin-8 (IL-8) were taken at five different time points: before the anesthesia induction (T1), 2 h after mechanical ventilation (T2), at the end of operation (T3), 6 h (T4) and 24 h (T5) after operation.The clinical pulmonary infection score (CPIS) was recorded at before anesthesia, days 1, 3, 5 and 7 after surgery.The incidence of postoperative pulmonary inflammation was also recorded.Results There was no statistical difference in the two groups with respect to age, body mass index, ASA physical status, intraoperative volume of infusion, estimated blood loss, urine volume, mechanical ventilation time, operation method and IL-6, IL-8 levels at T1-T5.Compared with T1, the IL-6 and IL-8 levels in two groups at T2-T5 increased significantly (P＜0.05).Compared that before anesthesia, CPIS in group CV on postoperative days 1, 3 and 5 increased significantly (P＜0.05);compared with group CV, CPIS and the incidence of postoperative pulmonary inflammation in group PV reduced significantly on postoperative days 1, 3 and 5 (P＜0.05).Conclusion Lung protective ventilation can not reduce perioperative IL-6, IL-8 levels in laparotomy elderly patients with COPD, but it can reduce the incidence of pulmonary inflammation and pulmonary infection within 5 postoperative days.

OBJECTIVETo investigate the therapeutic effect of Yiqi Huaju Recipe (YHR) combined with routine therapy on the blood pressure, the blood pressure variability and other cardiovascular risk factors in hypertension patients complicated with metabolic syndrome (MetS).

METHODSTotally 43 hypertension patients complicated with MetS were recruited in this study and randomly assigned to the treatment group (22 cases, treated with basic routine treatment +YHR) and the control group (21 cases, treated with basic routine treatment + placebo). The treatment course was 12 weeks. Detected were parameters such as 24-h ambulatory blood pressure monitoring (ABPM), body mass index (BMI), waist circumference (WC), waist to hip ratio (WHR), homeostatic model assessment for insulin resistance (HOMA-IR), fasting glycosylated hemoglobin A1c (HbA1c), fasting plasma glucose (FPG), 2 h postprandial plasma glucose (2 h PPG), fasting plasma insulin (FPI), serum lipid, etc.

RESULTSThe anthropometric parameters and plasma glucose levels (except HbAlc) were obviously lowered after treatment than before treatment in the treatment group (P < 0.01, P < 0.05). Besides, better effects were obtained in the WC, WHR, 2 h PPG, FPI and HOMA-IR (P < 0.05). The average blood pressure amplitude, the blood pressure variability, and blood pressure load at any time point were more obviously improved in the two groups after treatment than before treatment (P < 0.01, P < 0.05). Besides, partial indices were better in the treatment group than in the control group (P < 0.01, P < 0.05).

CONCLUSIONSYHR combined with routine therapy exhibited better effect on reducing the blood pressure amplitude, the blood pressure variability, and the blood pressure load in hypertension patients complicated with MetS. It could also effectively decrease the risk of other vascular disease.

OBJECTIVETo probe into the relation between acute respiratory infection and enterovirus (EV), season, age and sex of children in Beijing area.

METHODSNasopharyngeal secretion samples from 402 inpatient children with acute respiratory infection (ARI) were obtained, and EV RNA was detected by reverse transcriptase polymerase chain reaction (RT-PCR). The distribution of month, age and sex among the children positive for EV were analyzed.

RESULTSSeventy of the 402 cases were positive for EV RNA, the positive rate was 17.4 percent. The EV positive rate was 17.7 percent in children with lower respiratory tract infection, and 15.9 percent in children with upper respiratory tract infection. The EV positive rates were 0-36.1 percent in different months, which was the highest in the May (36.1 percent) and lower in December (4.3 percent). The positive rate of EV was 14.8 percent-21.9 percent in different age groups except for children 12 years of age and older, the positive rate was the lowest in the 4-6 years age group, and the highest in the 7 month-1 year age group. The EV infected boys and girls accounted for 16.2 percent and 19.7 percent of total numbers of boys and girls, respectively.

CONCLUSIONThe EV positive rate was higher in children with lower respiratory infection, which suggests that EV may play an important role in ARI of children. The EV positive rate was higher from late spring to autumn. EV infection was common in children under 12 years of age. The rate of EV infection was not significantly different between boys and girls.
