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 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 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.

The fermentation conditions of high 1.3 -propanediol-producing strain E. aero-N-56 were determined in this Paper. The optimum conditions of producing 1.3-PD were: initial pH 7.0, temperature 30℃, culture time 48 h, inoculum size 9% . 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.

Objective To investigate clinical features and therapeutic protocols of vulvovaginal-gingival syndrome(VVGS). Methods Clinical data were collected from 11 female patients with VVGS and analyzed. Results Among the 11 patients, the mean and median ages at a definite diagnosis of VVGS were both 46 years, and the average disease duration was 4 years. Painful erosive erythema was found on the vaginal vestibule in 7 patients, on the gingiva in 10, as well as on the bilateral buccal mucosa in 5. Additionally, 8 and 4 patients reported dyspareunia and vaginal hemorrhage, respectively. Seven patients were treated with low-dose oral methylprednisolone combined with hydroxychloroquine or colchicine, and the other 4 were treated with oral hydroxychloroquine alone. Furthermore, all of the 11 patients applied topical tacrolimus 0.1%ointment. Finally, 8 patients were cured or markedly improved. No obvious adverse reactions were observed in any of the patients. Conclusions VVGS mostly occurs in middle-aged women, with the vaginal vestibule and gingiva as predilection sites of painful erythema and dyspareunia as common symptoms. Patients have good responses to methylprednisolone combined with hydroxychloroquine, and hydroxychloroquine alone also shows good efficacy in patients with mild VVGS. Tacrolimus 0.1%ointment can be one of drugs for topical maintenance treatment of VVGS.

Ginkgo is one of the most successful cases of botanical drugs developed by modern science and technology during the past fifty years all over the world. At present ginkgo has been applied to the prevention and treatment of cardiovascular disease widely, and has good clinical efficacy. Type 2 diabetes has been proved to be the risk equivalents of cardiovascular disease, therefore it has an important scientific significance for looking for more effective drugs of prevention and control of diabetes. To seek more efficient and safe drug from the plant medicine which has the function of regulate blood sugar and improve insulin resistance becomes a hotspot at home and abroad. Basic and clinical studies have shown the ginkgo preparations of Chinese medicine have certain regulation effect on blood sugar and insulin resistance. In this paper, we review the mechanisms and clinical applications of ginkgo preparations on diabetes and its applications during the past 10 years.
