OBJECTIVE:To find out the main problems about quality supervision over Chinese herbal pieces and effective su-pervision strategies. MEDTHODS:First,static and dynamic models of the game between the enterprises engaged in the production and business of Chinese herbal pieces and local food and drug administration were respectively established,to which pure strategy Nash equilibrium analysis and mixed strategy Nash equilibrium analysis were made. Next,the model of the game between the supe-rior regulatory authorities and the basic-level regulatory authorities was established,to which mixed strategy analysis was made to find out the supervision factors relevant to the quality safety of Chinese herbal pieces. RESULTS & CONCLUSIONS:Based on the current situation of quality supervision over Chinese herbal pieces and the analysis results of the game models,it is suggested that at present the Chinese herbal medicine regulatory authorities of China should work hard to promote the reform of the supervision system,reduce supervision cost(including the guidance of the large-scale and centralized production of Chinese medicinal materi-als and unified appliance of approval number to the administration of Chinese herbal pieces),establish a systematic and comprehen-sive system of rewards and punishments,create a professional supervisor staff(including the strengthening of basic-level supervisor staff creation and the improvement of personnel's quality,the standardization of the law enforcement of regulatory authorities and the combination of proper power delegation to lower levels and strict supervision),and balance the relationship between the govern-ment and the public in supervision to increase the public's awareness of responsibility.

Objective To investigate the clinical efficacy of electroacupuncture plus acupoint application in treating diabetic constipation of yin deficiency and blood stasis type.Methods One hundred and fifty-six patients with diabetic constipation of yin deficiency and blood stasis type were randomly allocated to treatment and control groups, 78 cases each. The treatment group received electroacupuncture plus acupoint application and the control group, oral administration of mosapride citrate tablets. The TCM syndrome scores were recorded in the two groups before and after treatment. The clinical therapeutic effects were evaluated using the Constipation Scoring System (CSS), the Patient Assessment of Constipation Quality of Life (PAC-QOL) questionnaire and the TCM syndrome scores.Results There was a statistically significant post-treatment difference in the total efficacy rate based on CSS, PAC-QOL and the TCM syndrome scores between the two groups (P<0.05,P<0.01). There were statistically significant pre-/post-treatment differences in the TCM syndrome scores in the treatment group (P<0.05). There were statistically significant pre-/post-treatment differences in TCM syndrome dry mouth and tongue, thirst and dry stool scores in the control group (P<0.05). There were statistically significant post-treatment differences in TCM syndrome short breath, weakness, lassitude, stabbing pain, scaly dry skin, fixed pain, sore and weak loins and knees, and chest, palm and sole vexing heat scores between the two groups (P<0.01,P<0.05).Conclusion Electroacupuncture plus acupoint application is an effective way to treat diabetic constipation of yin deficiency and blood stasis type.

ObjectiveTo assess the relationship between the location,quantity and leukodystrophy of cerebral infarction and vascular cognitive impairment ( VCI ),and to compare the differences of the severity and domains of cognitive impairment among the different types of cerebral infarction,which will provide the pathophysiological evidence to the mechanism for the development of VCI. MethodThe patients suffering from cerebral infarction or leukodystrophy were recruited from either the ward or clinic in Tianjin General Hospital from April 2009 to April 2010,then assessed the cognition,and classified into different groups according to the location,size,quantity,whether or not they have leukodystrophy and the severity.The Logistic regression analysis was taken with whether or not the patients have had developed to the VCI as the dependent variable,and with the location,size,quantity,whether or not they have leukodystrophy and the severity as the independent variables.The differences of the score of NIHSS,Bathel index and the level of cognitive impairment were compared among patients with different types of lesions.Moreover,the difference of the score of MoCA for each cognitive domain were compared among patients with different types of lesions.ResultsThere was a relationship between key position infarction in the subcortex and white leukodystrophy with VCI.The position infarction in the subcortex and white leukodystrophy ( grade Ⅱ and Ⅲ ) might be the independent risk factors for the VCI( OR =1.752,2.135,3.753; 95% CI 1.533-3.821,1.541-6.787,1.432-6.821,all P <0.05).There were significant differences in the domains of excusive ability,attention,calculation,fluent language and orientation.The average scores of the domain of excusive ability in the subcortical group (3.40 ± 1.90) and the mix group (3.83 ± 1.27) were significantly lower than the cortical disease group(4.28 ± 0.89,t =0.050,0.857,both P < 0.05 ).The average scores of the domains of attention,calculation,fluent and orientation in the mix group were significantly lower than the subcortical group and cortical disease group.ConclusionsThere is a significant association of the key infarction in the subcortex and leukodystrophy with VCI.The patients with both the subcortex infarction and leukodystrophy are susceptible to VCI.The development of VCI is depended on the position of infarction instead of the quantity and size of infarction.The development of VCI is not only related to the white matter disease but also related to the severity of the leukodystrophy.The data highlights the need to small vessel disease.The patients with subcortical lesions mainly impair the executive ability.The patients with mix lesions may have more extensive domains and more severe cognitive impairment.

Objective To investigate the clinical value of gemstone spectral imaging (GSI) associated with patient-based low dose of contrast medium protocol in carotid CTA. Methods One hundred and twenty patients who were suspected with stenotic carotid artery or carotid plaque were prospectively enrolled in the study. All of them were divide into two groups by random number table. Group A (routine group): 60 were scanned with 120 kVp after the administration of moderate-concentration CM(320 mg/ml) with 5 ml/s injection velocity, Group B (low dose group):60 were scanned with GSI which was reconstructed using 50%ASiR after the administration of the same CM with 3 ml/s injection velocity. The contrast dose [(test bolus peak time +2 s – 5 s) × injection velocity] was calculated. Images of the two groups were compared in terms of arterial attenuation, signal-noise-ratio (SNR), contrast-to-noise ratio (CNR), and subjective image quality (IQ) score. The value of CT dose index volume (CTDIvol), dose length product (DLP) and effective dose (ED) was recorded, respectively. Data were analyzed by using independent samples t test or Mann-Whitney U test. Results The mean attenuation, noise, SNR, CNR, subjective image quality score, contrast dose, CTDIvol, DLP and ED of routine group was (363 ± 56)HU, (13 ± 4)HU, 30 ± 10, 38±13, 3.0 score, (69 ± 13) ml, 13.61 mGy,527 mGy · cm and 3.11 mSv, respectively. The above variables of low-dose-group was (378 ± 69) HU, (9 ± 4)HU, 48 ± 19, 62 ± 24, 2.0 score,(49 ± 7)ml, 12.72 mGy, 478 mGy · cm and 2.82 mSv, respectively. The mean attenuation and subjective IQ score of carotid artery had no significant differences statistically between two groups (P>0.05), respectively. The noise, SNR, CNR, contrast dose, CTDIvol, DLP and ED had significant differences statistically between two groups (P<0.05), respectively. Conclusion Compared with 120 kVp protocol, the use of GSI associated with patient-based low dose of contrast medium protocol in carotid CTA could provide equivalent image quality and higher SNR and CNR of carotid artery with a smaller amount of iodine and a lower radiation dose.

OBJECTIVE:
The objective of this study was to evaluate the effect of nasal packing, septal suture technique and vacuum sealing drainage (VSD) after septoplasty.
METHOD:
Ninety patients of nasal septal deviation in Combination with outfracture of the inferior turbinates who had received septoplasty were selected in this study. The patients were allocated into three groups, with thirty in each: for packing group, marcel materials were used for nasal packing after septoplasty; for suturing group, septal suture technique was performed after septoplasty; for VSD group, one drainage tube was used for negative pressure sucking after septoplasty without nasal packing. Postoperative signs and symptoms were compared between three groups. The comfort degree assessment included headache and nasal obstruction were evaluated by using visual analogue scale (VAS) at the 12th hour and 24 hour after operation. The edema in nasal cavity, hemorrhage. abscess,adhesive and healing rates after operation were compared among three groups.
RESULT:
The VAS score of headache and nasal obstruction and the severity of patient's conditions were significantly less in septal suture group and VSD group than that in packing group at the 12th and 24th hour after operation. The mucosa edema of nasal cavity was significantly slighter in septal suture group and VSD group than that in packing group at the third day after operation. The healing rates and number of complications are better in septal suture group and VSD group than those in packing group at the 7th day after operation. There were no hemorrhage or abscess in VSD group.
CONCLUSION
Septal suture technique and VSD after septoplasty can significantly relieve the distress of patients and reduce the healing time of mucosa in nasal cavity without increasing the risk of complications.

OBJECTIVE:
To observe the effect of tympanic injection of dexamethasone in the guinea pig endolymphatic hydrops and the change CFTR expression, to explore the effect of glucocorticoid treatment endolymphatic and its possible mechanism.
METHOD:
Thirty guinea pigs were divided into three groups: hormone group, water group, control group. The animals(hormone group, water group) in study were injected DDAVP 4 μg/kg in the first 7 d, and will increase to 6 μg/kg in the second 3 d. The control group was given normal saline, continuous 10 d. After twelfth days, the hormone group transtympanic injection of dexamethasone (5 mg/ml, 0.5 ml), and water group, control group transtympanic given normal saline (0.5 ml), continuous injection 5 d. Using immuno- histochemistry and Western blot to detect the cystic fibrosis transmembrane conductance regulator cochlear factor (CFTR) expression.
RESULT:
The water group ABR thresholds was significantly higher than that before the experiment (P < 0.01), and the water group was significantly higher than the rest of the groups (P < 0.01); Hormone group compared with the control group increased threshold value (P < 0.05). The control group had no endolym- phatic hydrops, the water group showed varying degrees of endolymphatic hydrops, cochlear duct and vestibular plus cochlear duct area ratio compared with the control group, hormone group was significantly higher (P < 0.01). hormone group area ratio was higher than the control group (P < 0.05). CFTR was primarily expressed in the stria vascularis, Corti's, spiral ligament, basilar membrane, cochlear ganglion,etc . The expression of CFTR in the water group was increased than that in the control group, and the hormone group (P < 0.01); the expression of hormone group increased compared with the control group (P < 0.05).
CONCLUSION
Tympanic injection of dexa- methasone can alleviate the desmopressin acetatein guinea pigs caused by membranous labyrinth, and the improve- ment of the hearing; Tympanic injection of dexamethasone can make the endolymphatic hydrops cochlea of guinea pigs decreased CFTR expression, indicating that the expression and possible mechanisms of CFTR intratympanic steroids reduce endolymphatic hydrops changes.

Objective:To investigate the effects of chronic anger stress on rats' aging process and the mechanism of the neuroendocrine-immune network. Methods:After the aging and brain aging rats induced by D-galactose(D-gal) were stimulated by anger, observation of the effects of chronic anger stress on the rats' spatial learning and memory was made, the contents of norepinephrine(NE), 5-hydroxytryptamine(5-HT)in brain tissue and serum, the levels of adrenocorticotropic hormone (CORT) in serum were assayed, the spleen index was measured. Results:Compared with the D-gal group, in the D-gal group stimulated by anger, the rats' ability of spatial learning and memory declined, the contents of NE in brain tissue and serum increased, the contents of 5-HT declined, the levels of CORT in serum increased, and the spleen index declined. Conclusion: The rats' aging and brain aging were aggravated and the aging process were accelerated by chronic anger stress. The possible mechanism were the sustained excitability of the HPA axis and SAS, disturbances of neuroendocrine system and immunological function repression.
