TCM is unique and e ective on senile dementia in both theory and practice;therefore it is signi cant to generalize TCM understanding and experience on senile dementia for speci c therapy to reduce patients' cognition impairment and enhance their living quality.Sorting of TCM understanding on senile dementia pathogenesis and causes,it was clear that seniledementia was often seen in aging people characterized by de ciency in origin and excess in super ciality.Its de ciency in origin was de ciency of kidney essence,marrow and lucid yang failing to ascend.The origin aspect of senile dementia was believed to be the insu ciency of kidney.The de ciency of ve zang-organs was closely related to it.While the super ciality aspect was thought to be turbid phlegm and stagnant blood blocking brain and cerebral meridian with ve zang-organs all concerned.On one hand,the de ciency of kidney assisted by the de ciency of ve zang-organs could result in phlegm and blood stasis,that is to say excess resulted from de ciency.On the other hand,the stagnation of phlegm and blood stasis could block the generation,transformation and transportation of qi,blood and body uid,which would further consume the essence of the body.This is so-called de ciency transformed from excess.The above two aspects a ected each other and causing lingering pathogenic factors.

Acute abdominal pain is a major clinical symptom of acute abdomen,and vasogenic acute abdomen caused by vascular diseases is rare and difficult to diagnose at its early stage with atypical clinical symptom and high mortality.Therefore,there is an urgent need to strengthen and improve the knowledge of surgeons about vasogenic acute abdomen.

Objective To evaluate the quality of life and care needs of hospitalized AIDS patients and analyze the relationship between them to provide basis for clinic nurses' helping patients to improve the quality of life. Methods We adopted the general information questionnaire, patient care needs assessment questionnaire, as well as the World Health Organization Quality of life Scale (WHOQOL)and used cluster sampling method to make face to face interviews with 36 hospitalized AIDS patients. Results The care needs of the 36 AIDS patients were at a high level,all areas of quality of life were lower than the norm. The quality of life of hospitalized AIDS patients was negatively correlated with the care needs. Conclusions Clinic nursing staffs should understand and assess the care needs of patients initiatively and take appropriate measures to improve quality of life of hospitalized AIDS patients.

Objective To evaluate the efficacy of thracheal extubation-insertion of the nasopharyngeal airway for preventing the response to extubation under anesthesia in patients with hypertension. Methods Eighty ASA Ⅱ or Ⅲ patients with hypertension, scheduled for laparoscopic cholecystectomy under general anesthesia were randomly allocated into 2 groups with 40 patients in each group: tracheal tube group (group Ⅰ ) and tracheal tube-nasopharyngeal airway group (group Ⅱ). Anesthesia was induced with midazolam 0.05 mg/kg, sufentanil 0.4 μg/kg, cisatracurium besylate 0.15 mg/kg and propofol 2 mg/kg. The patients were tracheal intubated and mechanically ventilated. Anesthesia was maintained with TCI of propofol (target plasma concentration 3-4 μg/L) and sufentanil (target plasma concentration 0.2-0.4 μg/L). BIS was maintained at 40-50. Target plasma concentrations of propofol and sufentanil were adjusted to 1 μg/L and 0.1 ng/L respectively after operation and the infusion was stopped after recovery of breathing. In group Ⅱ, extubation was performed, and then the nasopharyngeal airway was inserted and oxygen was inhaled by mask, and the airway was removed after recovery of consciousness. In group Ⅰ , extubation was performed after recovery of cousciousness. The SP, DP, HR and SpO_2 were recorded immediately before anesthesia induction (T_0), immediately and 2 min after insertion of the nasopharyngeal airway (T_(1,2)), and immediately and 2 rain after removal of the tube or airway (T_(3,4)). The maximal value of SP (SP_(max)), DP (DP_(max)) and HR (HR_(max)) were also recorded during extubation. The differences in SP (△SP), DP (△DP) and HR (△HR) before and after extubation were calculated. The plasma concentrations of AD and NE were determined. The coughing and restlessness were observed. Results The SP, DP, HR and plasma concentrations of AD and NE were significantly higher at T_(3,4) in group Ⅰ and the SP, DP at T_(1,3,4) and HR at T_(2,3) were significantly lower in group Ⅱ than those at T_0 (P<0.05). The SP, DP, HR and plasma concentrations of AD and NE were significantly lower at T_(2-4) in group Ⅱ than in group Ⅰ (P<0.05). The SP_(max), DP_(max), HR_(max), △SP, ADP and △HR were significantly lower in group Ⅱ than in group Ⅰ (P<0.05). The incidence of coughing and restlessness was obviously lower in group Ⅱ than in group Ⅰ (P<0.05). Conclusion Thracheal extubation-insertion of the nasopharyngeal airway under anesthesia can effectively prevent the patients' response to extubation during emergence from anesthesia.

Objective To evaluate the efficacy of the nasopharyngeal airway for airway management during anesthesia recovery in obese patients. Methods Eighty ASA Ⅰ-Ⅲ patients, aged 48-72 yr, body mass index > 30 kg/m~2 , were randomly divided into 2 groups (n=40 each) : nasopharyngeal airway group (group Ⅰ) and oropharyngeal airway group (group Ⅱ). The extubation was performed after recovery of breathing (RR ≥ 10 bpm, V_T≥5 ml/kg). The nasopharyngeal airway was inserted though the nasal cavity immediately after extnhation in group Ⅰ, and the oropharyngeal airway was inserted though the oral cavity after extubation in group Ⅱ. Oxygen (3 L/min) was then inhaled by mask until recovery of consciousness in both groups, and if SpO_2 < 90%, the rescue medication was given. The changes in RR, SpO_2 , HR, SP and DP were observed at 1 min (T_1), 5 min (T_2), 10 min (T_3) and 20 min (T_4) after insertion of the airway and complications were recorded in 20 min after insertion of the airway. Results The RR, SpO_2, HR, SP and DP were all maintained in the normal range after insertion of the airway in both groups. The RR,HR, SP and DP at T_(3,4) and incidence of resdessness, nausea and vomiting, and laryngospasm were significantly lower in group Ⅰ than in group Ⅱ (P<0.05), while there was no significant difference in SpO_2 at each time point between group Ⅰ and group Ⅱ(P>0.05). Conclusion The efficacy of the nasopharyngeal airway is similar to that of the oropharyngeal airway for the relief of the upper respiratory tract obstruction during anesthesia recovery in obese patients, but the stress response induced is lower and complications are fewer.

Members of the tripartite-motif (TRIM) protein family share a highly conserved domain architecture known as RBCC motif,which is composed of a RING finger domain,one or two B-box domains,a coiled-coil domain as well as diverse types of C-terminal regions.TRIM proteins can not only maintain the normal physiological functions of the body,but also regulate the development of various diseases.In the current review,we focus on recent advances in the structures of TRIM proteins and their functions in the development of viral infection,cancer and neurodegenerative disease.

OBJECTIVE To study the antibiotic resistance of Staphylococcus isolated from the burn patient wounds. METHODS The sensitivity to 14 common antimicrobial agents was deteded by K-B method. MRSA and MRCNS were detected by cefoxitin disk;the inducible resistance to clindamycin was detected by D-test. RESULTS There were 378 strains of Staphylococcus isolated from the burn patient wounds. The isolation rates of Staphylococcus epidermidis,S. aureus and S. haemolyticus were 43.1%,41.6% and 11.1%. Antibiotic resistance rate to vancomycin,teicoplanin,minocycline,rifapin and nitrofurantoin was 0.0-19.0%,the resistance rate to other antibiotics was 54.1-100.0%. The detection rate of MRSA was 81.5%,the detection rate of MRCNS among S. epidermidis and S. haemolyticus was 55.6% and 66.7%. The total positive rate of D-test was 48.2% in Staphylococcus which were sensitive to clindamycin but resistant to erythromycin. The positive rate of S. aureus,S. epidermidis and S. haemolyticus were 49.1%,44.2% and 57.1%. CONCLUSIONS Staphylococcus are ones of the important pathogens which make burn wound infection happen and the antimicrobial resistance is increasingly severe. The high positive results of MRSA and D-test make great trouble to therapy,and that should have taken more attention of clinic.
