Objective: To investigate the effect of berbamine hydrochloride on the absorption characteristics of berberine hydrochloride in different intestinal segments of rats in normal environment and high calcium environment. Method: Taking rat everted intestinal sac model,the content of berberine hydrochloride in absorbent solution of everted intestinal sac from different compatibility groups was determined by HPLC,and the uptake per unit area in different groups was analyzed by One-way ANOVA. Result: Compared with the normal J70 group(in normal environment,the concentration of berberine hydrochloride was 70 mg·L^-1) at the same time point,the uptake per unit area of the normal J70+Ver100 group(in normal environment,the concentration of berberine hydrochloride was 70 mg·L^-1,adding verapamil hydrochloride to a concentration of 100 mg·L^-1) was significantly increased in the ileum(P<0.05) at 120 min;the uptake per unit area values of the high calcium J70+A35 group(in high calcium environment,the concentration of berberine hydrochloride was 70 mg·L^-1,adding berbamine hydrochloride to a concentration of 35 mg·L^-1) were significantly increased in the duodenum(P<0.05) at 30,60,90 min;and the uptake per unit area values of the high calcium J70+A70 group(in high calcium environment,the concentration of berberine hydrochloride was 70 mg·L^-1,adding berbamine hydrochloride to a concentration of 70 mg·L^-1) were significantly increased in the ileum(P<0.05) at 30,90,120 min.By comparing with the normal group with the same mass concentration,the intestinal absorption of berberine hydrochloride was better in the high calcium J70+A35 group and the high calcium J70+A70 group. Conclusion: Berbamine hydrochloride can promote the absorption of berberine hydrochloride in intestine to a certain extent,especially in the high calcium environment.

Objective: To optimize purification process of total alkaloid extract of Berberis dictyophylla cortex by macroporous resin,and to establish its quality standard. Method: Acid dye colorimetry was used to investigate the purification process of total alkaloid extract of B. dictyophylla cortex,the process parameters included concentration of sample solution,speed of sampling,diameter-height ratio of resin column,water washing amount,concentration and dosage of eluent,flow rate of elution,etc.In order to determine the optimum process,HPLC was employed to determine the contents of four alkaloids(magnoflorine,jatrorrhizine hydrochloride,palmatine hydrochloride,and berberine hydrochloride) with mobile phase of acetonitrile-0.1% phosphoric acid aqueous solution for gradient elution and detection wavelength at 270 nm.After being purified,quality standard of total alkaloid extract of B. dictyophylla cortex was investigated according to the requirements in the 2015 edition of Chinese Pharmacopoeia.

Conclusion: This optimized purification process is stable and feasible, and the established quality standard is controllable.

[Objective]To explore the adverse pregnancy outcomes(APO)and examine the predictive value of umbil-ical artery Doppler in systemic lupus erythematosus(SLE)pregnancies.[Methods]Data of 273 pregnancies from 2010 to 2016 were analyzed retrospectively. Pulsatility index(PI),resistance index(RI),and systolic/diastolic ratio(S/D)of the umbilical artery flow velocity data were monitored by Doppler ultrasound.[Results]One or more APO occurred in 61.9% of patients with SLE,among which pregnancy loss occurred in 60 cases;preterm birth in 56 cases;intrauterine growth retardation occurred in 20 cases;and fetal distress occurred in 21 cases.Twelve of pregnancies resulted in neona-tal Lupus. In total,118 patients underwent fetal umbilical artery Doppler during 28~34 gestational weeks. Doppler PI, RI,and S/D were significantly higher in the APO groups than in the patients without APO.[Conclusion]Pregnancies in lupus still had an increased risk of APO.Umbilical artery Doppler was useful in predicting APO in lupus pregnancies.

OBJECTIVETo explore the correlation between pathological characteristics of target organs and excess evil syndrome in IgA nephropathy.

METHODSData were collected in multicenter cooperation. Totally 266 IgA nephropathy patients were typed into exogenous wind-heat affection syndrome (49 cases), lower energizer damp-heat syndrome (100 cases), damp-phlegm syndrome (43 cases), and blood stasis syndrome (74 cases). Meanwhile, percutaneous renal biopsy was performed in all patients for Hass classification, Oxford classification, Katafuchi integral, and Jiang's classification methods. The correlation between excess evil syndrome and pathological index was analyzed.

RESULTSFour syndrome types were correlated with their Hass levels (r = 0. 341, P <0. 01). Affection of exogenous wind-heat syndrome was correlated with segmental proliferation of endothelial cells and damaged active lesions of segmental capillary loops. Lower-energizer damp-heat syndrome was associated with Hass III level, destroying active lesions of capillary loops, segmental proliferation of endothelial cells, glomerular segmental lesions, focal interstitial infiltration of inflammatory cells, focal interstitial fibrosis and tubular atrophy. Blood stasis syndrome was associated with Hass IV level, glomerular sclerosis, segmental glomerulosclerosis (S)/adhesion, mesangial hypercellularity (M), angiohyalinosis, multi-foci interstitial infiltration of inflammatory cells, multi-foci interstitial fibrosis and tubular atrophy. Phlegm-damp syndrome had higher proportions of Hass I and III levels, but with no association with other pathological parameters.

CONCLUSIONSExcess evil syndrome was associated with partial pathological characteristics of IgA nephropathy. It could reflect pathological damage degree of target organs, activities, chronic lesions, and prognosis of IgA nephropathy to certain extent. Correlated pathological characteristics and its evolution could indicate excess evil syndrome types and their evolution rules.

OBJECTIVETo observe the efficacy of Jianbu Tongluo Xunzheng Liquid (JTXL) in treating knee osteoarthritis (KOA), and to explore the correlation between changes of infrapatellar fat pad scanned by CT and the efficacy.

METHODSTotally 105 KOA outpatients were randomly assigned to three groups, i.e., the treatment group, the control group, and the combination group, 35 in each group. Patients in the treatment group were fumigated by JTXL, 30 min each time, once daily, 10 times as a course of treatment, 3 courses in total. Those in the control group received intra-articular injection of Sodium Hyaluronate Injection (SHI), 3 mL each time, once per 6 days, 5 times in total. Those in the combination group were treated by fumigation of JTXL + intra-articular injection of SHI in the same way as the aforesaid two groups. All patients were treated for 30 days. Their clinical efficacy and changes of infrapatellar fat pad scanned by CT were observed, and their correlation was analyzed.

RESULTSThe total effective rate was 88.57% in the combination group, better than that of the control group (74.29%) and the treatment group (80.00%; both P < 0.05). Besides, the score for knee joint functions at Hospital for Special Surgery (HSS) was better in the combination group than the other two groups (P < 0.05). The anteroposterior diameter, exterior-interior diameter, the superior-inferior diameter were shortened, and the density decreased in the treatment group and the combination group (P < 0.05). Besides, they were superior to those of the control group (P < 0.05).

CONCLUSIONSChanges of infrapatellar fat pad scanned by CT only existed in the combination group and the treatment group, indicating changes of CT scanning was only correlated with effect on changing physicochemical properties of infrapatellar fat pad. Treatment by Chinese medicine could omnipotently and balanced regulate functions and structures of every tissue. Therefore, CT could be taken as a better method for clinical efficacy observation by Chinese medicine.

OBJECTIVETo observe changes of brain glucose metabolism by needling at Waiguan (SJ5) in cerebral infraction (CI) patients using 18F-fluorodeoxyglucose (FDG) positron-emission computer tomography (PET/CT), thus exploring its effect and mechanisms.

METHODSA total of 21 patients with CI were recruited in this study. The location of lesion was limited to the left basal ganglia by CT or MRI scan. All patients were randomly assigned to three groups. i.e., the acupoint group (Group A), the non-acupoint group (Group B), the blank control group (Group C), 7 in each group. Patients in Group A were needled at right Waiguan (SJ5). Those in Group B were needled at non-acupoint [10 mm beside Waiguan (SJ5)], whereas those in Group C did not receive any treatment. All patients underwent PET/CT head scan. All data were statistically analyzed using SPSS 13.0 Software and SPM8 Software.

RESULTSCompared with Group C, glucose metabolism increased in bilateral superior temporal gyrus (BA38), right superior frontal gyrus (BA9), left cingulate gyrus (BA24), left culmen and pyramid of cerebellum, and right cerebellar tonsil of cerebellum in Group A. Compared with Group C, glucose metabolism increased in bilateral superior frontal gyrus (BA6, BA9, BA10), bilateral middle frontal gyrus (BA6, BA10), left middle frontal gyrus (BA4), bilateral uncus of limbic lobe (BA36, BA38), left cingulate gyrus (BA24, BA31), left posterior cingulate gyrus (BA30), left precuneus (BA7), left inferior parietal lobule (BA4), and left lingual gyrus of occipital lobe (BA18) in Group B. Compared with Group B, glucose metabolism increased in bilateral superior temporal gyrus (BA22, BA38), right inferior frontal gyrus (BA47), left culmen and cerebellar tonsil of cerebellum in Group A. Activated encephalic regions of needling at Waiguan (SJ5) were mainly dominated in the healthy side, bilateral superior temporal gyrus, and right inferior frontal gyrus. Activated encephalic regions of cerebellum were located at the left cerebellar hemisphere, left culmen of anterior cerebella lobe, and bilateral cerebellar tonsil of posterior cerebella lobe.

CONCLUSIONSNeedling at Waiguan (SJ5) of CI patients induced increased glucose metabolism in local cerebral regions. Functional neuroimaging using PET/CT could directly reflect changes of brain glucose metabolism by acupuncture.

Splintage external fixation in Chinese Mongolian osteopathy is a biological macroscopic model. In this model, the ideas of self-life "unity of mind and body" and vital natural "correspondence of nature and human" combine the physiological and psychological self-fixation with supplementary external fixation of fracture using small splints. This model implies macroscopic ideas of uncovering fixation and healing: structural stability integrating geometrical "dynamic" stability with mechanical "dynamic" equilibrium and the stability of state integrating statics with dynamics, and osteoblasts with osteoclasts, and psychological stability integrating closed and open systems of human and nature. These ideas indicate a trend of development in modern osteopathy.
