1. Endoscopic nasal lateral wall dissection approach for benign lesions of maxillary sinus
Academic Journal of Second Military Medical University 2010;30(5):561-564
Objective: To report our experience on endoscopic nasal lateral wall dissection approach for treatment of refractory benign maxillary sinus diseases. Methods: The data of 8 patients, who had relapsing maxillary diseases 2 to 4 times after maxillary sinus or ethmoid sinus surgery, were retrospectively analyzed. The patients included 6 males and 2 females,with an average age of (55 + 14) years(41-69 years). Under general anesthesia the operation started from an incision in front of the inferior turbinate (IT),then the lacrimal duct(LD) was dissected to form a IT-LD flap. The flap was placed inwardly and the maxillary sinus lesion was removed under endoscope. The inferior antrostomy was performed when necessary. The possibility of maxillary sinus malignant lesions was ruled out by postoperative pathology. Results: Postoperative pathological findings confirmed that the lesions were all benign. The follow-up period ranged from 6-14 months. Five patients were cured and 3 were improved 6 months after operation. There were no complications such as cheek numbness, epiphora, orbital hemorrhage, visual disorder or cerebrospinal fluid rhinorrhea during follow-up. Conclusion:The endoscopic nasal lateral wall dissection approach provides a wider vision field and allows for a thorough removal of maxillary sinus lesions, while reserving the LD and IT.

To study the effect of different storage conditions and storage time on herb quality of Lonicera macranthoides, different packaging materials including vacuum plastic bags, plastic bags, woven bags, sealed with endometrial bags, paper bags, sack bags were selected for the study under different storage conditions including room temperature, 5 degrees C refrigerator, low temperature of - 20 degrees C refrigerator and desiccator. Twenty-four batches of samples were used for the study, and active ingredients were determined. The experimental results showed that the ingredients in each storage group changed with the storage time, storage conditions (storage environment, packaging). Under the same storage time, the storage environment (temperature, humidity) had effect on the stability of herb quality. Low temperature had less effect on herb quality. The effect of packaging on herb quality was as following: plastic vacuum packaging > woven with endometrial sealed packaging > plastic bag > woven bag > sack bags > paper bags. Under the same storage conditions, with the increase of storage time, caffeic acid content increased slowly, and other five ingredients content decreased gradually. Storage time affected significantly on the intrinsic quality (chemical composition) and appearance of herb. It is suggested that low temperature (5 degrees C), dark and sealed storage are suitable for storage of L. macranthoides herb, the storage time should be not more than 24 months.

Objective To investigate the current status and influencing factors of falls self-efficacy among the stroke elderly patients.Methods Totally 170 elderly stroke patients were investigated using the Modified Falls Efficacy Scale (MFES),and they were tested with Berg Balance Scale (BBS) and Time Up and Go Test (TUGT).Results The average score of falls self-efficacy was 108.There were 50.6% elderly stroke patients assigned to the group with low falls self-efficacy.Multiple Logistic regression analysis indicated that impairments of balance and mobility,severe stroke-related disability were the independent influencing factors associated with FOF,which could explain 52.0% of variations.Conclusions Low falls self-efficacy among the stroke elderly patients is a common complaint,nurses and physicians should focus on this problem,interventions combining exercise and education of accidental falls should be taken to improve falls self-efficacy of elderly stroke patients,and prevent falls finally.

This study was aimed to optimize the extraction technology of Shu-Feng Ding-Chuan(SFDC) granules in the Huang-Qin(HQ)group by Box-Behnken response surface methodology(RSM).With three major characteristic components (baicalin,praeruptorin A and solid content in extraction liquid),the effects of four factors,such as the concentration of ethanol,the dosage of ethanol,the duration of extraction and the extraction times,were investigated by the single factor experiment.Then,the range of parameters of key factors was further studied and explored by Box-Behnken RSM.The results of single factor experiment and Box-Behnken design showed that the optimum preparation conditionswere 8-fold 70% ethanol,extracted for 2 times,with 1.0 h per each time.Under these conditions,the transfer rates of baicalin and praeruptor in A were 89.57% and 87.90%,respectively.And the transfer rateof solid content was 32.35%.It was concluded that the single factor experiment combined with RSM can be used in theoptimization of extraction technology for SFDC granules in the HQ group.This technique wasstable and feasible,which provided scientific evidences for the industrial production.

Purpose To explore the relationship between the mutations of epidermal growth factor receptor ( EGFR) and KRAS genes and clinicopathological characteristics in patients with non-small cell lung cancers (NSCLC). Methods Clinical samples from 431 NSCLC patients were obtained for EGFR and KRAS gene analysis. PCR based direct DNA sequencing was used to investigate mutations in exon 18-21 of EGFR gene and codon 12 and 13 of exon 2 of KRAS gene. Results The overall EGFR mutation rate of primary NSCLC was 53. 6% (231/431) in this study cohort and eight cases showed double EGFR mutations. Mutation rates in female and male were 65. 2% (122/187) and 46. 9% (98/209), respectively. The mutation rate was higher in patients with non-smokers and adeno-carcinoma and adenosquamous carcinoma subtypes than in their counterparts (P<0. 05), with the percentage of 57. 2% (124/216), 60. 3% (199/330), 42. 9% (6/14), respectively. In squamous cell carcinomas and other subtypes, EGFR mutation rates were 11. 6% (5/43) and 11. 1% (1/9), respectively. The EGFR mutation types included exon 18 point mutations (4. 0%, 9/227), exon 19 deletion mutations (4. 5%, 101/227), exon 20 insert or point mutations (9. 7%, 22/227) and exon 21 point mutations (41. 4%, 94/227). Activating mutations of KRAS gene were detected in 7. 8%(31/396) of NSCLC. Twenty-eight patients showed codon 12 mutations ( G>T, G>A, G>C) , and three patients had codon 13 mutations ( G>A, G>T) . Most of these mutations were G to T transversion (64. 5%, 20/31). Conclusion Polymerase chain reaction-direct sequencing is a reliable and effective method for the detection of the EGFR and KRAS gene mutation in NSCLC patients. The mutation rate of EGFR is higher in Chinese patients, especial-ly in non-smoking female patients with adenocarcinoma.
