Objective To study the clinical effect of ceramic cover anterior on teeth beauty.Methods 138 teeth in 34 patients with dental fluorosis were divided into two groups,the control group (69 teeth in 16 patients) was given traditional PFM cover repair,the treatment group (69 teeth in 18 patients) was given ceramic cover,they were followed up for three years.The teeth remaining rate and patient satisfaction were compared,the match color,edge fit,healthy gums,restoration integrity were compared according to the Ryge standard.Results Teeth remaining rate in treatment group was 95.7％,which was significantly higher than control group (P ＜ 0.05).The patient satisfaction was 94.4％ in treatment group and 87.5％ in the control group,the difference was significant (P ＜ 0.05).The match color,edge coloring,healthy gums and teeth sensitivity were not different between the two groups (P ＞ 0.05).The restoration integrity and marginal fit of treatment group was better than control group (P ＜ 0.05).Conclusion The clinical effect of ceramic faced in the anterior teeth beauty repair,especially in the repair of dental fluorosis is remarkable,and the remaining teeth rate higher,repair,dental restoration integrity and marginal fit is significantly better than that of resin repair,patient satisfaction is higher,the water area from non-beryl popularization and application.

Objective: To prepare modern tradional Chinese patent medicine Lemai capsules with a low dosage. Methods: Comparing the applications of seven kinds of macroporous adsorption resin in refinement of Lemai capsules' extracts in danshensu and paeoriflorin determined by HPLC as markers. Results: After refinement, the solid content of extracts decreased greatly. The content of danshensu became much lower than that before refinement The retention rate of AB 8、 X 5 and WLD for paeoriflorin is up to 80%. Conclusion: 7 kinds of macroporous adsorption resin are not proper to danshensu but some of them can be used to paeoriflorin.

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.

AIM: To improve the quantitive method of sarsasapogin in Kangbindu Tablet(Rhizoma Anemarrhenae, Fructus Forsythiae, etc.) METHODS: Applying HPLC-ELSD to replace TLCS. RESULTS: The new method was better than the old one in precise and repeat. CONCLUSION: The new method HPLC-ELSD is more useful.

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.

Objective To compare the anesthetic efficacy of dexmedetomidine and midazolam combined with sufentanil in patients undergoing microwave coagulation therapy for liver cancer.Methods Forty ASA Ⅱ male patients (aged 35-62 years and weighing 45-70 kg) scheduled for percutaneous microwave coagulation therapy were randomly divided into two groups (n =20 each):midazolam group (group Ⅰ) and dexmedetomidine group (group Ⅱ).A loading dose of midazolam 40 μg/kg (in normal saline 20 ml) was given intravenously over 10 minutes,followed by midazolam infusion at 40 μg·kg-1 · h-1 in group Ⅰ.And a loading dose of dexmedetomidine 1 μg/kg (in normal saline 20 ml) was given intravenously over 10 minutes,followed by dexmedetomidine at 0.5 μg· kg-1 · h-1 in group Ⅱ.At 5 minutes after administration of the loading dose of midazolam or dexmedetomidine,a loading dose of sufentanil 0.2 μg/kg was given,and then patient-controlled intravenous anesthesia (PCIA) with sufentanil (with the background infusion of 0.1 μg·kg-1 · h-1,bolus dose of 0.1 μg/kg and lockout interval of 3 minutes) was used.The operation was started 2 minutes after administration of the loading dose of sufentanil.The incidences of bradycardia,tachycardia,hypotension,hypertension and respiratory depression were recorded.The total attempts and effective pressing times of PCIA were also recorded.Results There was no significant difference in the incidences of bradycardia,tachycardia,hypotension,and hypertension between the two groups (P ＞ 0.05).The incidence of respiratory depression was significantly lower,and the total attempts and effective pressing times were smaller in group Ⅱ than in group Ⅰ (P ＜ 0.05).Conclusion The anesthetic efficacy of dexmedetomidine and sufentanil is better than that of midazolam and sufentanil in patients undergoing microwave coagulation therapy for liver cancer.

Objective To evaluate the feasibility of using corrected body weight to set the tide volume for mechanical ventilation during general anesthesia in obese patients.Methods Ninety-six ASA physical status Ⅰ or Ⅱ obese patients,with a body mass index of 28-44 kg/m2,scheduled for elective extremity surgery under general anesthesia,were divided into 3 groups (32 cases of each group) by random digits table method:tide volume based on actual body weight group (group A),tide volume based on ideal body weight group(group B),and tide volume based on corrected body weight group(group C).The pulmonary function of all patients was normal.The patients were endotracheally intubated and mechanically ventilated after induction of anesthesia.According to the corresponding body weight,the initial tide volume was set based on 8 ml/kg in each group(respiratory rate:15 bpm).At 10 min after start of mechanical ventilation,peak airway pressure (Ppeak),airway plateau pressure (Pplat),airwayresistance (Raw) were recorded.Arterial blood samples were collected at 30 min of mechanical ventilation for blood gas analysis and arterial blood oxygen partial pressure (PaO2),arterial blood carbon dioxide partial pressure (PaCO2) and the patients requiring readjustment of tide volume were also recorded.Results The level of Ppeak,Pplat,Raw in group B and group C were significantly lower than those in group A[(15.3 ± 1.8),(18.5 ± 2.6) cmH2O (1 cmH2O =0.098 kPa) vs.(23.2 ±3.3) cmH2O; (11.5 ± 1.6),(14.3 ± 1.4) cmH2O vs.(17.6 ±2.7) cmH2O; (10.8 ± 1.7),(12.5 ± 2.6) cmH2O/ (L·s) vs.(16.8 ± 3.0) cmH2O/ (L·s)],and the level of PaCO2 in group B and group C was significantly higher than that in group A [(48.8 ± 3.1),(40.2 ± 2.3) mmHg (1 mmHg =0.133 kPa) vs.(28.6 ± 3.8) mmHg],there was significant difference(P ＜ 0.01).The level of PaO2 and oxygenation index in three groups had no significant difference (P ＞ 0.05).There were no patients requiring readjustment of tide volume in group C,however,93.8％ (30/32) patients required readjustment of tide volume in group A and 81.2 ％ (26/32) in group B,there was significant difference (P ＜ 0.01).Conclusion Corrected body weight based on 8 ml/kg can be used to set the tide volume for mechanical ventilation during general anesthesia in obese patients with normal pulmonary function.

Combining with traditional medical ethics for medical students to carry out the cultivation of core so -cialist values is a specific and realistic path .Virtue ethics features of traditional medical ethics are good for medical students to internalize core socialist values .Normative characteristics of traditional medical ethics are good for med-ical students to be cultivated of social responsibility , sense of responsibility to life , dedication and integrity aware-ness .By demonstrating the role of ethics and ancient doctors′model in classic literature , students can not only un-derstand the rich connotations of traditional ethics of traditional culture , but also get the cultivation and practice of core socialist values .
