OBJECTIVETo study the correlation between Chinese medical types of coronary heart disease (CHD) [i.e., phlegm turbidity syndrome (PTS) and qi deficiency syndrome (QDS)] and their metabolites.

METHODSRecruited were 65 CHD patients including 37 cases of PTS and 28 cases of QDS. Serum endogenous metabolites in the two syndrome types were determined by gas chromatograph-mass spectrometer-computer (GC/MS), and their differences between their metabolic profiles analyzed.

RESULTSMore than 100 chromatographic peaks were totally scanned. Chromatograms obtained was matched with mass spectrum bank, and finally we got the category contribution value of 46 kinds of substances. Results of MCTree analysis showed patients of PTS and patients of QDS could be effectively distinguished. Compounds contributing to identify the two syndromes were sequenced as serine, valine, 2 hydroxy propionic acid. Comparison of metabolites showed contents of serine and 2 hydroxy propionic acid were higher in patients of PTS than in patients of QDS (P<0.05).

CONCLUSIONThe differences in the metabonomics of CHD TCM syndrome types could provide material bases for TCM syndrome differentiation of CHD, indicating that metabonomics technologies might become a new research method for TCM syndrome typing.

OBJECTIVETo observe the effect of Yijing Recipe (YR) on the apoptosis of testis spermatogenic cells and the protein expression of Bcl-2/Bax in rats with adenine induced infertility.

METHODSTotally 75 Wistar rats were randomly divided into 5 groups, i.e., the blank control group, the model group, the high dose YR group, the middle dose YR group, and the low dose YR group, 15 in each group. Except those in the blank control group, rats in the rest groups were intragastrically administered with adenine for 10 successive days. From the 11th day, rats in the blank control group and the model group were fed with equal volume of normal saline. Rats in the YR groups were intragastrically administered with YR at different doses (3.38 g/100 g; 1.69 g/100 g; 0.85 g/100 g), once daily for 20 consecutive days. All rats were killed by the end of the experiment and their testes extracted. The apoptosis of spermatogenic cells and the expression of Bcl-2/Bax proteins were detected by terminal deoxynucleotidyl transferase-mediated biotinylated UTP nick end labeling (TUNEL) and SABC method.

RESULTSCompared with the blank control group, the Bcl-2 protein expression decreased, the Bax protein expression increased, and the apoptosis index increased in the model group, showing statistical difference (P <0.01). Compared with the model group, the Bcl-2 protein expression increased in the three YR treated groups (P <0.01, P <0.05). The Bax protein expression level decreased in the high and middle dose YR groups (P <0. 01, P <0. 05). The apoptosis index decreased in the middle dose YR group (P <0.01).

CONCLUSIONYR could inhibit the apoptosis of spermatogenic cells through regulating the expression of Bcl-2 and Bax protein in the testis.

Objective:To investigate the impact of aging on the correlation between the intestinal microorganism Akkermansia and obesity, and to analyze the features of the correlation in the elderly population. Methods:This was a cross-sectional study.A total of 6896 cases were collected from the Guangdong intestinal microbiome in 2018, aged 18-94 years old, including 3806 females, 1641 cases with abdominal obesity(23.7%)and 707 cases with systemic obesity(10.3%). The 16S rRNA sequencing data were from individuals of Cantonese descent.The abundance of Akkermansia was calculated after data cleaning, clustering and annotation.The type of abdominal obesity or systemic obesity was diagnosed based on the standards of the Working Group on Obesity in China(2002). According to the five quintiles of the abundance of Akkermansia, subjects were divided into Q1~Q5(Q1-Q4: n=1379, Q5: n=1380). Logistic regression was used to study the relationship between Akkermansia and obesity after adjusting for common confoundors such as gender.Subjects were subgrouped into two types of age groups: the <65 group(n=5467)and the ≥65 group(n=1519); the <70 group(n=6136)and the ≥70 group(n=850). Age windows were used to analyze changes in characteristics of this relationship with increasing age. Results:There were significant differences in age and gender among different Akkermansia groups( t/ χ2=3.51, -5.03, P<0.01). Logistic regression analysis showed that after adjusting for two main confounding factors, age and gender, the risk of systemic obesity and abdominal obesity gradually decreased from Q2 to Q5 group, compared with Q1 group( P<0.001). The correlation between Akkermansia and obesity decreased with age.The protective effect of Akkermansia on obesity was weaker in the ≥65 and ≥70 groups, respectively, than in the <65 and <70 groups. Conclusions:Akkermansia is a protective factor for obesity, but the protective effect is affected by aging and weakened in the elderly.

Background Bevacizumab is primarily aimed at pathologic angiogenesis for off-label uses such as the treatment of ocular neovascular disorders.However,as a new anti-fibrotic and anti-angiogenic agent following trabeculectomy,the safety and efficacy of bevacizumab by multiple-time and high-dose subconjunctival injection are still under study.Objective This study was to assess the safety and efficacy of bevacizumab after multiple-time and high-dose subconjunctival injections.Methods Regular trabeculectomy filtration surgery was performed on both eyes of 18 clean New Zealand White rabbits 0.1ml of bevacizumab(25g/L) was subconjunctivally injected intraoperatively and 3,5,7 days postoperatively in the left eyes of rabbits,and no any intervene in the right eyes were as normal controls.Bleb morphology was examined every 2 days and graded based on Moorefield's criteria and compared between the bevacizumab-treated eyes and normal saline(NS) eyes.The animals were sacrificed at 10,20 and 30 days after surgery respectively.The histopathological changes of the blebs were detected by hematoxylin and eosin stain to evaluate the cellular element around the bleb,and Masson stain was used to assess the degree of fibroblast proliferation.The degree of vascularity of bleb was identified by anti-vWf stain.Approval of this protocol was obtained and permitted from People's Hospital Institutional Animal Care and Use Committee of Peking University.The use of experimental animals complied with the Regulation for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission.Results Compared to the NS-treated eyes,bevacizumab-treated eyes showed the larger and more diffusely elevated blebs with the significant difference(2.48±0.22cm2 versus 1.73±0.27cm2,t=5.194,P＜0.05).The survival time of the filtration bleb in bevacizumab panel was longer in bevacizumab-treated eyes compared to control eyes,showing a significantly difference between them(21.0±1.56 days versus 12.5±1.97 days,t=3.830,P=0.005).Histological and immunohistochemical analysis confirmed that bleb and adjacent conjunctiva vascularity(A value) was significantly less in bevacizumab-treated eyes than that in control eyes at 20 days after surgery with the difference value 14320.7±4134.9(t=12.275,P＜0.05),and fibroblast deposition value was evidently diminished after bevacizumab treatment at 30 days following surgery in comparison with control eyes with the mean difference 0.27±0.03(t=15.980,P＜0.05＝.Conclusion Repeated subconjunctival injection of bevacizumab can effectively prolong the survival time of bleb in a rabbit model of trabeculectomy and limit the degree and area of vascularization in 30 days following surgery.Bevacizumab inhibit fibroblast-meditated tissue formation significantly in the later phase of vascularization after trabeculectomy.

OBJECTIVETo observe the effects of acupuncture at "Feishu" (BL 13) and "Lingtai" (GV 10) on distribution taxis of paclitaxel in mice with lung cancer to discuss targeted relationship between acupoints and corresponding viscera.

METHODSAccording to randomized digital table, 315 SPF-grade BALB/C female mice were divided into 7 groups: blank group (group A), model group (group B), medication group (group C), acupuncture at non-acupoint group (group D), acupuncture at Feishu group (group E), acupuncture at Lingtai group (group F) and acupuncture at Feishu and Lingtai group (group G), 45 mice in each one. Except the blank group, the remaining groups were treated with N-nitroso-tris-chloroethyl urea (NTCU) to establish the model of squamous-cell carcinoma. After model establishment, group A, group B and group C were not treated with acupuncture; group A and group B were treated with intraperitoneal injection of 0.9% sodium chlorvde solution by 6 mL/kg while group C was treated with intraperitoneal injection of paclitaxel by 6 mL/kg. The group D, group E, group F and group G were treated with acupuncture at non-acupoint, "Feishu" (BL 13), "Lingtai" (GV 10) and "Feishu" (BL 13) plus "Lingtai" (GV 10), respectively, then were intraperitoneally injected with paclitaxel by 6 mL/kg. The treatment was all given once a day for continuous 10 days. 15 min, 30 min, 1 h, 2 h, 8 h, 12 h and 24 h after the treatments, 6 mice in each group were randomly selected and sacrificed to collect samples of lung, liver, spleen, kidney and heart, etc. High performance liquid chromatography was applied to measure the concentration of paclitaxel in each organ (lung, liver, spleen, kidney and heart) at different time points.

RESULTS(1) The content of paclitaxel in lung, kidney and heart reached the peak at 2 h, then decreased significantly in group C, group D, group E, group F and group G; the content of paclitaxel in spleen showed downtrend at each time point. The content of paclitaxel in liver reached the peak at 2 h in group C and group D; the content of paclitaxel reached the peak at 8 h in group E, group F and group G. (2) The content of paclitaxel in lung in group E and group G was higher than that in group C and group D at each time point (all P < 0.01); the content of paclitaxel in lung in group F was higher than that in group C (P < 0.01) and group D (P < 0.01) only at time point of 2 h. The content of paclitaxel in lung in group G was higher than that in group F at each time point (all P < 0.05). There was no statistical difference between group G and group E (all P > 0.05).

CONCLUSIONAcupuncture at "Feishu" (BL 13) and "Lingtai" (GV 10) could influ- ence the metabolism of paclitaxel in lung-cancer mice, leading to distribution change in each organ. As a result, it could cause targeting effects, which is more significant at "Feishu" (BL 13) and "Lingtai" (GV 10).

OBJECTIVETo investigate the protective effect of Shenfu injection (SFI) on cardiac function of patients undergoing valve replacement operation under cardio-pulmonary bypass.

METHODSOne hundred and twenty patients undergoing valve replacement operation under cardio-pulmonary bypass were randomly divided into the SFI group and the control group, 60 in each group. Intravenous infusion of 1 ml/kg SFI was given to the SFI group, 30 min before anesthesia, and to the control group, equal volume of normal saline was given instead. The following indices were observed: (1) the hemodynamic changes occurred in the operational period; (2) the dosage of vaso-active drugs used during and after operation; (3) the post-operational recovery time of patients.

RESULTSThe mean arterial pressure and heart rate in the SFI group during operation were higher, while the central venous pressure was lower than those in the control group (P < 0.05). The dosage of vaso-active drugs, such as dopamine, dobutamine, sodium nitroprusside and lidocaine, used during and after operation was lower, and the extubation time and the intensive care unit (ICU) staying time were shorter in the SFI group when compared with those in the control group (P < 0.05).

CONCLUSIONSFI has certain protective effects on the cardiac function of patients undergoing valve replacement operation under cardio-pulmonary bypass.
