Objective To optimize the extraction method of salviae miltiorrhizae madix et rhizoma in Huoluo-Xiaoling granules. Methods According to the contents of Salvianolic acid B and Tanshinone Ⅱ A, the extraction method was established by comparing different solvents (water and 70% ethanol)and extracting modes (compound extraction and single herb extraction). Then orthogonal design was used to determine the optimum extraction method. Results Considering the contents of salvianolic acid B and tanshinone Ⅱ A, 70% ethanol extract was better than water extract and compound extraction was better than single herb extraction.The optimum extraction condition was 70% ethanol in eight times of the herbs weight, extracted for 1h by 3times. Conclusion The extraction method was simple and stable.

OBJECTIVETo establish method for determining the contents of alpha-pinene and octyl acetate in Boswellia serrata, in order to provide preference for making quality standards for B. serrata and processed B. serrata.

METHODApplication of orthogonal design was employed to optimize the solvent, solvent quantity and extraction time. The GC-MS analysis was performed on a Rxi-5ms silica capillary column, running in the electron impact (EI) mode, with ion trap and injector temperature of 200 degrees C and 250 degrees C, respectively. The column oven was initially 50 degrees C and was held for 1 min after injection, followed by temperature ramping at 5 degrees C x min(-1) up to 130 degrees C, holding for 1 min. 1 microL of samples solution were injected in the split mode (1:60). Helium was the carrier gas. The mass spectrometer was set to scan m/z 45450 with an ionizing voltage at 70 eV.

RESULTSample solutions were prepared for 50-fold dose by ultrasonic extraction with hexane for 30 min. The content of alpha-pinene and octyl acetate in 10 batches of B. serrata were 0.021 3-0.149 5, 2.519 6-9.098 0 mg x g(-1), respectively. And, those of alpha-pinene and octyl acetate in processed B. serrata were 0.015 9-0.065 9, 0.801 0-12.812 2 mg x g(-1).

Objective To investigate the influence of type 2 diabetes mellitus(T2DM)on cognitive function and the effective connectivity with in the default mode network(DMN)in the brain.Methods A total of 93 hospitalized patients diagnosed with T2DM were enrolled in this study as T2DM group from The First Affiliated Hospital of Guangzhou University of Chinese Medicine during September 2021 to December 2022.Simultaneously,108 healthy individuals were recruited from the community as normal control(NC)group.The cognitive functions were evaluated in the two groups.A random dynamic causal modeling approach was employed to analyze the effective connectivity within DMN in both groups.Additionally,Pearson correlation analysis was performed to examine the association between differential connectivity,clinical indicators,and cognitive scores in both groups.Results In comparison to the NC group,T2DM individuals exhibited statistically significant reductions in scores in the auditory verbal learning test(AVLT)for immediate recall and the digit symbol substitution test(DSST)(P＜0.05).Additionally,they displayed a notable decrease in effective connectivity from the left lateral parietal cortex(LLPC)to the posterior cingulate cortex(PCC),as well as from the LLPC to the right lateral parietal cortex(RLPC)within the DMN(P＜0.05).Pearson correlation analysis unveiled a negative association between HbA1c levels and the strength of effective connectivity from LLPC to PCC.Conversely,a positive correlation was observed between AVLT(immediate)scores and the strength of effective connectivity from LLPC to PCC and LLPC to RLPC.Additionally,DSST scores displayed a positive correlation with the strength of effective connectivity from LLPC to PCC(P＜0.05).Conclusion Patients with T2DM display compromised effective connectivity from LLPC to PCC and LLPC to RLPC within the DMN network,and this alteration may associated with cognitive impairment.

Objective:To explore the surgical efficacy of conductive deafness caused by otosclerosis and ossicular malformation with 980 nm fiber laser stapedial floor fenestration.Methods:Data of 58 patients (ears) who were diagnosed with conductive deafness caused by otosclerosis (49 ears) and ossicular malformation (9 ears) treated by 980 nm Diode laser small-fenestra stapedotomy were retrospectively analyzed. Air conduction (AC) thresholds, bone conduction (BC) thresholds, and air-bone gap (ABG) at 0.5, 1, 2, 4 kHz pure tone frequencies were compared before and 3 months after surgery, and the advantages and precautions of 980 nm fiber laser were summarized. Paired t-test (SPSS 26.0 software) was use to analyze the listening data. Results:Fiber optic laser stapes fenestration and artificial stapes implantation were successfully completed in all 57 cases (ears), the hearing of another one patient (ear) with floating malformation of detachment of stapedial floor was lower than that before surgery. Preoperative at 0.5, 1, 2, 4 kHz frequencies of AC thresholds, BC thresholds, and ABG were (65.4±9.7) dB, (27.2±8.9) dB, and (38.2±9.8) dB respectively. Postoperative 3 months at the same frequency of AC thresholds, BC thresholds, and ABG were (42.1±11.3) dB, (26.9±6.6) dB, and (15.2±9.1) dB. Preoperative and postoperative of AC threshold and ABG were statistically significant at 0.5, 1, 2, 4 kHz ( t value was 13.270 and13.948, both P<0.01), and yet the BC threshold was not statistically significant before and after surgery at the same frequency ( t=0.418, P>0.05). Conclusions:980 nm fiber laser stapes floor fenestration is an effective treatment for conductive deafness caused by otosclerosis and ossicular malformation.
