Objective To explore a better method to diagnose the brachial plexus injury as pre-or post-ganglionic,which is quick,simple,quantitative,cheap and accurate.Methods Forty-five SD rats were divided randomly ino pre-or post-ganglionic brachial plexus injury models group,and the choline acetyl- transferase(CHAT)activity was detected by using the radioisotope after different days.Results The ChAT activity of two groups both fall day by day:in the pre-agnglionic group,it falls quickly,and reach 1/10 of nor- mal(675?258)cpm;in the post-ganglionic group,it falls slowly,and reach 1/2 of normal even after 90 days (4906?1119)cpm.Conclusion Intra-operative measure of ChAT can be used to differentiate pre-or post- ganglionic brachial plexus injury.

Objective To investigate the present incidence and the risk factors of retinopathy of prematurity (ROP).Methods The clinical data of 1 356 premature infants who were born in our hospital from Dec 2008 to Feb 2011 with birth weight of 2 500 g or less and gestational age of 37 weeks or less were analyzed retrospectively,and divided into ROP group(n =208) and without ROP group(n =1 148).They were screened for ROP from 4 ～ 6 weeks of chronological age or 32 weeks of postmenstrual age.Results In 1 356 cases,there were 208 cases with ROP,the incident rate was 15.34％,of which 36 cases were severe diseases (2.65％).Compared with the infants without ROP,the development of ROP was correlated with birth weight [(1 528 ±243) g vs (1 960 ± 187) g],gestational age [(30.92 ±0.72) weeks vs (32.87 ± 1.28) weeks],oxygen uptake time ＞ 8 d (123 cases vs 865 cases),pulmonary surfactants (18 cases vs 216 cases),septicemia (42 cases vs 154 cases),in utero distress (63 cases vs 511 cases) and anemia (64 cases vs 237 cases) (P ＜ 0.05).Logistic regression analysis suggested that birth weight,gestational age,oxygen uptake time ＞8 d,septicemia and pulmonary surfactants were significant risk factors associated with the development of ROP(P ＜ 0.05).Meanwhile,there were significant differences in the incidence of infants with ROP at different birth weight and different gestational age (P ＜ 0.05).Conclusion The birth weight and gestational age are lower,the incidence of ROP is higher and the disease is more serious.The probability of ROP,particularly severe ROP,is highest in the most immature infants while it is lower in the least immature ones.

OBJECTIVE: To investigate the clinical manifestation, diagnosis, treatment of parathyroid occupying lesions. METHOD: The clinical data of 26 patients with parathyroid occupying lesions between January 2003 and October 2012 at Dalian Central Hospital were retrospectively analyzed. RESULT: There were 2 cases of parathyroid cancer, 11 cases of parathyroid adenoma, 13 cases of parathyroid cysts in this study. All the cases,except 13 cases of cysts, are accompanied by symptoms of hyperparathyroidism. The symptoms were as follows:26 cases of neck lump, 11 cases of osteoporosis/osteitis fibrosa cystica,9 cases of urinary symptom, 8 cases of digestive symptom. Serum calciumion level and serum parathyroid hormone(PTH) level were examined qualitatively before operation. Ultrasonography, CT, MRI were used in diagnosing and locating parathyroid occupying lesion before operation. 2 cases of parathyroid cancer, 11 cases of parathyroid adenoma and 13 cases of parathyroid cysts with preoperative and postoperative diagnosis coincidence rate was 0 (0/2), 91% (10/11), 69% (9/13). All patients were treated with operation. 2 cases of parathyroid cancer survived with out recurrence during follow up for 17 months and 27 months after operation. 11 cases of parathyroid adenoma and 13 cases of parathyroid cysts were treated with operation,achieved complete remission and the outcome was no recurrence. CONCLUSION There lack of specific clinical symptoms of parathyroid occupying lesions,neck lump are common manifestations. Examination of serum calcium and PTH level together with ultrasonography, CT, MRI, 99mTc-MIBI is helpful to diagnose parathyroid occupying lesions. Parathyroid cancer preoperative diagnosis is difficult . Parathyroid occupying lesions determine the diagnosis depends on pathology. Surgery should be done as primary treatment.

Objective To study the expression and significance of monocyte chemotactic protein-1 (MCP-1/CCL2) and vascular endothelial growth factor (VEGF) in serum samples of oral squamous cell carcinoma (OSCC) patients.Methods The concentrations of CCL2 and VEGF in the serum was assessed by ELISA in healthy donors (n=27) and OSCC patients (n=85).Then analyzed the correlation between the concentrations of CCL2 and VEGF and the relationship with patients' clinicopathological characteristics.Results CCL2 concentration was lower in OSCC patients than in healthy donors (69.12 ± 19.54 pg/ml vs 103.41 ± 34.42 pg/ml,t =6.477,P＜0.05).The expression of CCL2 was positively associated to TNM stage in OSCC (t=2.193,P＜0.05).VEGF concentration was higher in OSCC patients than in healthy donors (145.76 ± 49.34 pg/ml vs 70.35± 14.93 pg/ml,t=3.92,P＜0.05).There was a negative correlation between CCL2 and VEGF (r=-0.216,P＜0.05).The receiver operating characteristic (ROC) curve suggests that CCL2 and CCL2/VEGF in serum are good diagnostic markers to discriminate healthy people from OSCC patients,the cutoff values was 98.61 pg/ml and 0.82.Conclusion The expression of CCL2 and VEGF in serum correlated to OSCC progression,and it can be a potential diagnostic biomarker for oral disease.

Under the optimum conditions: the 1.3-PD productivity reached up to 23.68 g/L?d; the 1,3-PD yield of E. aero-N-56 up to 47.36 g/L in 30 L fermentor.

OBJECTIVETo explore the clinical effects of Mobi-C cervical artificial disc replacement (CADR) and anterior cervical decompression and fusion (ACDF) in treating single cervical disc herniation.

METHODSFrom June 2009 to June 2012, the clinical data of 27 patients with single cervical disc herniation were retrospectively analyzed. There were 18 males and 9 females, aged from 30 to 62 years old with an average of 46.7 years. Of them, 12 patients were treated with CADR (CADR group) and 15 patients with ACDF (ACDF group). All patients had pain and numbness in neck, shoulder and upper limbs, and courses of disease was from 1 to 13 months with an average of 2.4 months. The data of clinical evaluation and questionnaire survey about quality of life were collected before operation, postoperative at 1 week and final follow-up. Odom criterion was used to evaluate postoperative effect. Visual analogue scale (VAS) was used to record pain levels. Neck disability index (NDI) and health questionnaire SF-36 were used to assess the quality of life.

RESULTSNo complications about nerve and blood vessel were found and the patients were followed up from 6 to 30 months, with an average of 16 months. One week after operation, 10 cases got excellent results and 2 good in CADR group; 5 cases got excellent results and 10 good in ACDF group; there was significant difference between two groups (P<0.05). At final follow-up, 10 cases got excellent results and 2 good in CADR group; 12 cases got excellent results and 3 good in ACDF group; there was no significant difference between two groups (P> 0.05). Pain of upper limbs had obviously relieved between two groups at 1 week after operation and final follow-up (P<0.05). VAS of neck and NDI in CADR group had decreased respectively from preoperative 3.58±0.79, 23.42±6.36 to 0.58±0.51, 5.42±1.68 at 1 week after operation (P<0.05); but the index in ACDF group was no obvious at 1 week after operation. At final follow-up, VAS of neck and NDI and SF-36 score were obviously improved than preoperation (P<0.05) between two groups.

CONCLUSIONMobi-C CADR retains the movement unit in the decompression segment and can quickly recover normal action for patients. Using CADR method has a good curative effect in the early phase, and the clinical effect is reliable, may improve the quality of life.
