Traditional Chinese medicine is considered to have a lot of advantages in many ways when compared with modern medi-cine;however, the advantages are usually difficult to be widely accepted due to lack of evidence. Under the background that the evi-dence-base is paid universal attention all over the world, there is no doubt that it will bring negative effects on the development of tradi-tional Chinese medicine. Providing scientific and rational evidence base is essential for the healthy development of traditional Chinese medicine, and pharmacoeconomic is expected to play an important role in the area. The paper reviewed the study and application status of traditional Chinese medicine and pointed out the main problems, and furthermore, the corresponding countermeasures and sugges-tions were put forward in order to promote the research and application of pharmacoeconomic in the field of traditional Chinese medi-cine.

OBJECTIVE: To design and synthesize a series of hybrids of anilinopyrimidines and cinnamic acids and to find powerful anti-non-small cell lung cancer(NSCLC) drug. METHODS: Compounds 3a-3k were synthesized by combining anilinopyrimidines scaffolds and cinnamic acid derivatives through amide bonds, then the anti-NSCLS activity of these compounds was studied by MTT. RESULTS: Their structures were confirmed by MS and 1H-NMR. Most of target compounds displayed higher anti-proliferative activity on EGFR-mutant H1975 cells(IC50=0.83-3.31 μmolL-1) than gefitinib(IC50=8.59 μmolL-1). CONCLUSION: Compound 3b has the best inhibitory effect on H1975 cells. Therefore, 3b may be a potential anti-NSCLC agent for further investigation.

BACKGROUND:Calcitonin gene-related peptide has been confirmed to induce osteogenic differentiation, but whether it can induce the osteogenic differentiation of adipose-derived stem cells under three-dimensional culture to construct tissue-engineered bone is rarely reported.
OBJECTIVE:To investigate the feasibility of exogenous calcitonin gene-related peptide to induce osteogenic differentiation of adipose-derived stem cells combined with calcium alginate gel in three-dimensional condition.
METHODS:Adipose-derived stem cells were gained by col agenase I digestion of the subcutaneous adipose tissue of both inguinal regions of New Zealand rabbits. Passage 3 cells were mixed with sodium alginate to prepare calcium alginate gel, and then the cells were assigned into two groups and cultured in 24-wel plates. Adipose-derived stem cells in the control group were cultured in Dulbecco’s modified Eagle’s medium/Ham’s nutrient mixture F-12 supplemented with 10-2 mol/Lβ-glycerophosphate sodium, 10-7 mol/L dexamethasone, 50 mg/L ascorbic acid, 10%fetal bovine serum. While, adipose-derived stem cells in the experimental group were incubated with the same medium as above, but 1.5 μg/L calcitonin gene-related peptide was added. The cells proliferation and the mRNA expressions of col agen I and osteocalcin were detected by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide and reverse transcription-PCR respectively, and alkaline phosphatase and calcium concentration were detected at different induction time.
RESULTS AND CONCLUSION:The cellproliferation curves were S shaped. The absorbance values of the experimental group were higher than those of the control group at1, 3, 5, 7, 14, 21 days after osteogenic induction (P<0.05). Alkaline phosphatase and alizarin red staining of adipose-derived stem cells was al positive, but golden round nodes became more and bigger in the experimental group compared with the control group after 2 weeks. At 7 and 14 days, col agen I and osteocalcin mRNA expressions were higher in the experimental group than in the control group. Alkaline phosphatase activity and calcium concentration of the experimental group were higher than those of the control group at 1, 2, 3, 4 weeks after osteogenic induction (P<0.05). Results showed that the calcitonin gene-related peptide can induce the osteogenic differentiation of adipose-derived stem cells combined with calcium alginate gel.

Type 2 diabetes mellitus (T2DM) is characterized by hyperglycemia and dyslipidemia. Carvacrol (CAR) has demonstrated the potential to mitigate dyslipidemia. This study aims to investigate whether CAR can modulate blood glucose and lipid levels in a T2DM rat model by regulating short-chain fatty acids (SCFAs) and the GPR41/43 pathway. The T2DM rat model was induced by a high-fat diet combined with low-dose streptozocin injection and treated with oral CAR and/or mixed antibiotics. Fasting blood glucose, oral glucose tolerance, and insulin tolerance tests were assessed. Serum lipid parameters, hepatic and renal function indicators, tissue morphology, and SCFAs were measured. In vitro, high glucose (HG)-induced IEC-6 cells were treated with CAR, and optimal CAR concentration was determined. HG-induced IEC-6 cells were treated with SCFAs or/and GPR41/43 agonists. CAR significantly reduced blood lipid and glucose levels, improved tissue damage, and increased SCFA levels in feces and GPR41/43 expression in colonic tissues of T2DM rats. CAR also attenuated HG-induced apoptosis of IEC-6 cells and enhanced GPR41/43 expression.Overall, these findings suggest that CAR alleviates blood lipid and glucose abnormalities in T2DM rats by modulating SCFAs and the GPR41/43 pathway.

OBJECTIVE: To compare the hearing test data of the profound hearing-impaired children with the hearing aids and with cochlear implants; to find out the useful method to measure the residual hearing. METHOD: Twenty-two profound hearing-impaired children participated in the study with complete set of hearing test and verbal rehabilitation file. Ten children fitted hearing aids and underwent verbal rehabilitation more than 3 months. Among the other 12 children with cochlear implants, 10 children fell in the same year range with the hearing aid patients. The children with hearing aids were divided into two groups according to the achievement of the verbal rehabilitation. ASSR threshold and pure- tone threshold were compared between the groups. RESULT: (1) ASSR test: 7 children (14 ears) with hearing aids achieved good verbal representation, in which ASSR threshold can be recorded on 2.71 frequency on average [(110.92 +/- 7.43) dB HL]. Among 3 children with hearing aids representing poor verbal achievement and 5 children with additional cochlear implant because of the poor verbal achievement with hearing aids, only 1.06 frequency had response of ASSR test [(110.88 +/- 48.52 ) dB HL]. (2) Pure tone audiometry: the average threshold of the 7 children with good representation was (96.11 +/- 7.81) dB HL, and the threshold on 3 frequency were less than 100 dB HL on average. The average threshold of the other 3 children with poor verbal achievement was (112.19 +/- 5.15) dB HL, and none of the frequency threshold was 100 dB HL. CONCLUSION The number of the frequency with the response of ASSR and the threshold < or =100 dB HL of pure tone audiometry is an effective indication of the useful residual hearing.

OBJECTIVE: To elucidate the relationship between different cephalometric measurements and the severity of childhood OSAHS, then analyze the value of cephalometric measurements in predicting the severity of OSAHS in children. METHOD: Sixty-one patients received PSG examination and standard lateral neck roentgenography including cervical trachea. Cephalometric measurements include adenoid size, adenoidal-nasopharyngeal ratio, narrowest posterior airway space of nasopharynx, ratio of the narrowest posterior airway space of nasopharynx and trachea diameter. Statistical analysis was made to study the relationship between the data of Cephalometric measurements and PSG. RESULT: Cephalometric measurements were all associated with AHI and AI (P < 0.01). Only PAS/TD variable was entered in the stepwise linear regression equation. ROC curve analysis revealed that the optimal probability cut-off in predicting moderate and severe OSA using PAS/TD ratio was 0. 658, with the area under the curve being 0.799. The corresponding sensitivity and specificity were 81.8% and 76.5% respectively. There was no correlation between cephalometric measurements and LSaO2 (P > 0.01). CONCLUSION PAS/TD is useful and simple in predicting the severity of OSAHS in children, but no use in predicting the severity of arterial oxygen saturation.

OBJECTIVE: To investigate the characteristics of heart rate (HR) and heart rhythm in children with obstructive sleep apnea-hypopnea syndrome (OSAHS). METHOD: Ninety-five patients underwent overnight PSG for clinically suspected OSAHS. According to the apnea index (AI), the patients were assigned to control group (AI < or = 1/h, SaO2 >92%, n = 27) or OSAHS group (AI > 1/h, SaO2 < 92%, n = 68). The HR and heart rhythm were monitored and compared between the two groups. RESULT: The maximum HR during sleep was significantly higher in OSAHS group while the minimum HR was significantly lower during sleep. Bradycardia and tachycardia is a common feature of pediatric OSAHS. There was a significantly higher incidence of tachycardia in OSAHS groups than in the control group. CONCLUSION These findings suggest that pediatric OSAHS might influence HR and heart rhythm.

OBJECTIVE: To analyze the clinical manifestations and the cause of misdiagnosis of congenital vallecular cyst. METHOD: Nineteen cases of congenital vallecular cysts were collected and reviewed retrospectively. Their clinical manifestations and diagnosis were analyzed. RESULT: Their clinical manifestations included inspiratory stridor, respiratory distress, inspiratory dyspnea, feeding difficulty etc. Among 19 cases, 15 cases were misdiagnosed as neonate pneumonia (9 cases), bronchial pneumonia (5 cases), and laryngitis (1 case), respectively. All cases were diagnosed as congenital vallecular cysts by fibrolaryngoscope. The diagnosis was confirmed by pathological examination. CONCLUSION Congenital vallecular cyst is fairly uncommon. To cure these patients on time, early examination of upper airway is recommended for patients with inspiratory stridor and inspiratory dyspnea. Fibrolaryngoscope would be useful for diagnosis and timely treatment.

OBJECTIVE: To investigate the pathogenic bacteria distribution and drug susceptibility in children with acute otitis media (AOM) in different age and different season in the Pearl River Delta region. METHOD: Four hundred and forty-two children diagnosed as AOM were divided into three groups by age factor and four groups by season factor. Midge ear pus collecting and culturing were used for bacteria and antimicrobial susceptibility test. RESULT: (1) Strains of bacteria were isolated from 356 children with the positive rate of 80.5%. Streptococcus pneumoniae (39.2%), staphylococcus aureus (25.9%) and haemophilus influenzae (7.4%) were the most frequently isolated pathogens. (2) Streptococcus pneumoniae was the main pathogenic bacteria in 0-1 year group and > 1-3 years group (P < 0.05), staphylococcus aureus was the most frequently isolated pathogen in >3 years group (P < 0.05); (3) In the season groups, the number of children with AOM decreased significantly in July-September group. There was no significant difference of streptococcus pneumoniae distribution among the four groups (P > 0.05). Staphylococcus aureus was the main pathogen in January-March group (P < 0.05); (4) Drug sensitivity shown that linezolid and ofloxacin were most sensitive to streptococcus pneumoniae and staphylococcus aureus, and macrolides had a good therapy effect to haemophilus influenzae. CONCLUSION The pathogens distribution and drug susceptibility in children with AOM were varies in different age and different season. As a result, a treatment should be done based on the climate, environment, and pathogens distribution of a region.
