Objective: To investigate the expression and distribution of NOS2 and NOS3 in human non-small cell lung cancer (NSCLC),and to evaluate the relationship between their expression and tumor angiogenesis and lymph node metastasis. Methods: the expression of NOS2, NOS3 and IMVD in 95 patients with NSCLC were examined using immunohistochemical methods (S-P), and the relationship between them and many clinicopathological parameters was analyzed. Results: The positive expression of NOS3 was associated with histological subtype, IMVD and lymph node metastases of NSCLC(P

Systems biology, which includes genomics, proteomics, transcriptomics and metabolomics, is an integration of system theory and biology. It studies the life phenomena with thinking method of systems theory. And it provides an important methodological basis and technical conditions for recognizing syndrome of traditional Chinese medicine (TCM) and mechanism of therapeutic effect from multiple disciplines and perspectives. Systems biology is similar to the core idea of TCM system and holism concept. Therefore, systems biology can be used as a platform and pivot of non-alcoholic fatty liver disease (NAFLD) in modern TCM study. Systems biology will accelerate the modernization research of TCM in the prevention and treatment of NAFLD. It will also provide new ideas and methods for TCM study on NAFLD.

Results 135 cases of peripheral nerve injury, 22 cases of normal part degeneration in 81 cases, completely denatured 32 cases, the positive rate was 83.70%(P<0.05). Among 30 cases of electromyography and nerve conduction velocity determination, 28 cases results. Conclusion It has a certain value and significance of neuromuscular electrical diagnosis instrument for peripheral nerve injury rehabilitation evaluation.

Objective To investigate the effectiveness of intratympanic dexamethasone injection as a protec-tion agent against cisplatin ototoxicity.Methods Fifty five healthy guinea pigs were randomly divided into four groups.The guinea pigs groups received (group I)0.9% NaCl solution(16 ml/kg)intraperitoneally (IP),(group II)dexamethasone (10 mg/ml)intratympanically(IT),(group III)cisplatin (16 mg/kg)only intraperitoneally(IP) and (group IV)dexamethasone (10 mg/ml)IT followed after 1h by 16 mg/kg cisplatin.Before and 7 days following injections,the ototoxic effect was measured with auditory brainstem response(ABR).The contents of malondiade-hyde(MDA)and activities of superoxide dismutase(SOD)were also measured.Results ABR thresholds before and after dosing were 28.50±4.74,29.00±3.94 dB nHL and 28.67±5.82,31.33±5.81 dB nHL in group I and group II,respectively,with no significant differences (P>0.05).The contents of MDA and activities of SOD were 2.01 ±0.07 mmol/L ,234.10±13.09 U/ml and 2.06±0.09 mmol/L,233.20±13.24 U/ml in the group I and group II, respectively,with no significant differences (P>0.05).ABR thresholds after dosing were 55.33±4.81,and 40.67 ±3.72 dB nHL in the group III and group IV,which were significantly increased,but ABR thresholds in the group IV were significantly lower than that in the group III (P<0.05).The contents of MDA were 5.74±0.17,3.51± 0.18 mmol/L in the group III and group IV,which were significantly increased.SOD activities were 107.90 ± 14.21,and 162.70±11.25 U/ml,which significantly decreased.Nevertheless,in the group IV dexamethasone rela-tively reduced the contents of MDA(P<0.001)while increased the activities of SOD(P<0.001)compared with group III.Conclusion Intratympanic dexamethasone injection presents as an effective treatment modality to prevent cisplatin ototoxicity without any ototoxic effect.

Objective To investigate the possibility and surgical effect of simultaneous tympanoplasty to chronic suppurative otitis media in the period of infection. Methods Forty-eight cases (48 ears) with chronic suppurative otitis media in the period of infection (31 with cholesteatoma, 17 with caries) were underwent simultaneous Wullstein Ⅱ and Ⅲ tympanoplasty on the complete elimination of the lesions (typical or modified mastoidectomy). Results All eases had dry ears within 4-10 weeks with average of 7 weeks. The air-bone gap within 10 dB was in 11 eases, 15 to 20 dB in 25 cases, 25 to 30 dB in 9 eases, no change or worse in 3 eases. Conclusions Infection is not the absolute eontraindication to the tympanoplasty in treating chronic suppurative otitis media, Wullstein Ⅲ tympanoplasty plus mastoid cavity obliteration and eonchaplasty is a suitable choice to treating chronic suppurative otitis media on the complete elimination of lesions and reconstruction of the ventilation system among mastoid cavity, tympanum and eustachian. The malfunction of eustachian is the main eanse to failure of surgery.

OBJECTIVE To investigate the feas-ibility of preserving parotid duct in regional excision of pleomorphic adenoma. METHODS 32 patients with parotid pleomorphic adenoma were treated by regional excision with the preservation of the parotid duct. RESULTS No relapse occurred during 3-6-year follow-up period. Transient facial nerve palsy occurred in only 3.1%(1/32) of patients and the drainage of the parotid duct on the surgical side was preserved. CONCLUSION Remaining function of the parotid gland function was preserved and the facial nerve was well-protected in the regional excision of pleomorphic adenomas, especially for patients with small pleomorphic adenomas.

Objective To determine if the carbon dioxide (CO 2) pressure used in laparoscopic cholecystectomy (LC) has any effect on the occurrence of postoperative shoulder pain. Methods One hundred and twenty consecutive patients undergoing LC were prospectively divided into three groups(40 patients in each group): Patients in group A underwent LC with 10 mm Hg of CO 2, those in group B with 12 mm Hg of CO 2, and in group C with 14 mm Hg of CO 2. PaO 2?PaCO 2?pH before and after LC were recorded. Shoulder pain was recorded on a visual analogue pain scale 1,3,6,12,24,48,72,96 h after operation. Results The intraoperative CO 2 consumption was significantly higher in group C (F=11.38,P

Objective To explore the efficacy of ketogenic diet( KD) in the treatment of status epi-lepticus( SE) and whether KD could protect the brain,and propose a new thought on SE patients′reasonably individualized treatment, brain protection and prognosis improvement. Methods From Sep 2013 to Jan 2015,all the patients diagnosed as SE were advised to apply KD treatment; the patients who refused KD treatment were included in the control group,while the patients who accepted KD treatment were included in the treatment group. Based on the SE treatment principles,the control group applied traditional anti-convulsive therapy,while the treatment group applied traditional therapy combined with KD treatment. Before the treat-ment and after the epilepsy control,the patients′ serum was collected to test neuron specific enolase( NSE) and S100βlevels,and the duration of epilepsy control was recorded. Results The treatment group included a total of 10 patients; 3 patients had a good efficacy and obtained seizure-free after the treatment; clinical seizures declined significantly in 6 patients. The treatment group′s overall response rate was 9/10,which was higher than that of the control group(5/8)(P<0. 01). The treatment group′s duration to gain efficacy was shorter than that of the control group[(5. 2 ± 2. 9) d vs. (9. 8 ± 1. 5) d,P<0. 01]. After the treatment,the patients′NSE and S100β in both groups were significantly decreased than those before the treatment ( P<0. 001 or P<0. 05). After the treatment,the serum NSE and S100β of the patients in the treatment group were lower than those in the control group,with statistically significant difference(P<0. 05). Conclusion Frequent epileptic seizures and SE would impair the patient′s brain. Controlling the epileptic seizures actively could lower the severity of brain injury. KD could effectively control the epileptic seizure and had neuropro-tective effects.

The ancient books on traditional Chinese medicine are mainly covered in the comprehensive bibliogra-phies and special bibliographies of traditional Chinese medicine in the past ages.Their classification was thus de-scribed in the Seven-Classification System, Four-Classification System, Twelve-Classification System,Bibliogra-phy of medical collection and General Bibliography of ancient books on traditional Chinese medicine, followed by an analysis of the classification systems of ancient books on traditional Chinese medicine in the past ages and their evo-lution, which helps to search the medical literature from the vast ancient books according to their classification.

This article was aimed to study constructive standards for the database of traditional Chinese medicine (TCM) documentation. Refer to relevant national standards, specifications and other fields of universal standards such as metadata specification of health information dataset, medical science data sharing, metadata standard, data of pop-ulation health sciences shared metadata standard, basic scientific data sharing network project standard, Chinese A-cademy of Sciences data application environment construction and service standards, combined with the specification for TCM literature resources, Chinese medicine literature database was constructed. The results showed that 6 major categories and 17 specifications were established to standardize the construction of TCM literature database. It was concluded that the standardization of TCM literature database was able to realize TCM literature database construc-tion standard and process, and to facilitate the sharing of TCM data resources.
