Non-invasive treatment to grade 1 essential hypertension by percutaneous laser and electric pulse to acupoint with music: A randomized controlled trial.

OBJECTIVE: To study a non-drug therapy for hypertension disease by combining percutaneous laser and electric pulse stimulation to acupoint with music, and to test the efficiency of the combining treatment to grade 1 essential hypertension. METHODS: A total of 174 patients with grade 1 essential hypertension were randomly assigned to 3 groups with a random number table after Chinese medicine (CM) syndrome differentiation: the photoelectric and musical treatment group (Group 1, with a self-developed multi-mode audio frequency pulse photoelectric therapeutic apparatus), acupuncture group (Group 2), and oral placebo group (Group 3), 58 cases per group. The curative effect of each group was evaluated by the changes of blood pressure and CM syndrome integral before and after treatment. RESULTS: Compared with Group 3, there were significant decrease of blood pressure and CM syndrome integral in Group 1 and Group 2 (P<0.01). Compared with Group 2, Group 1 showed the highest decrease in systolic pressure (P<0.017). The total effective rate of anti-hypertension in Group 1 (91.38%, 53/58) was significantly higher than that in Group 2 (74.13%, 43/58) and Group 3 (18.97%, 11/58, P<0.05 or P<0.01); and that in Group 2 was also significantly higher than that in Group 3 (P<0.01). There were significant difference in the total effective rate of CM syndrome integral in both Group 1 (93.10%, 54/58) and Group 2 (84.48%, 49/58) as compared with Group 3 (17.24%, 10/58, P<0.01), while there was no significant difference between Group 1 and Group 2 (P>0.05). CONCLUSIONS: The multi-mode audio frequency pulse photoelectric therapeutic apparatus, combining music, laser and electric pulse stimulation, is clinically useful for grade 1 essential hypertension. This "three in one" therapy method is non-invasive, easy and simple to handle. It is expected to be popularized as a new alternative treatment.

Traditional Chinese medicine: Pivotal role of the spleen in the metabolism of aristolochic acid I in rats is dependent on oatp2a1.

The genotoxicity and cytotoxicity of aristolochic acids is well documented, and the Aristolochiaceae plant family has been widely used in China and India for medical purposes. However, the mechanisms of aristolochic acid I (AAI) in treatment and toxicity remain to be fully elucidated. According to the theory of traditional Chinese medicine (TCM), the spleen is responsible for transportation and transformation, in which a substance is transformed, absorbed and distributed in the body. In the present study, rats were randomized into a blank group without spleen deficiency and a spleen deficiency group to investigate the metabolism of AAI. The results showed that the concentration of AAI was higher in the spleen deficiency group, compared with that of the blank group. To further elucidate this process, the expression of organic anion transporting peptide (oatp)2a1 in the rats of the two groups were examined following oral administration of AAI. It was observed that the mRNA level of oatp2a1 in the small intestine of the blank+AAI 60 min group was downregulated, compared with that in the blank group. Compared with the mRNA level of oatp2a1 in the spleen deficiency group, the expression levels in the lung and liver were downregulated in the spleen deficiency+AAI 5 min group, whereas expression levels in the kidney in the spleen deficiency+AAI 60 min group were upregulated. Based on the above results, it was hypothesized that the expression of oatp2a1 may be one of the mechanisms of AAI metabolism in rats. In TCM, the spleen and certain functions of the small intestine, are important in AAI metabolism, and affect the toxicity of AAI. In addition, the lung, liver and kidney may also be involved in spleen deficiency syndrome in rats.

Effect of the herbal formulation Jianpijiedu on the TCRVßCDR3 repertoire in rats with hepatocellular carcinoma and subjected to food restriction combined with laxative.

The aim of this study was to investigate the effects of the Chinese herbal formulation Jianpijiedu (JPJD) in a rat model of orthotopic hepatocellular carcinoma (OHC). The tumor-bearing rats underwent food restriction combined with laxative (FRL) treatment in order to model the nutritional and digestive symptoms of patients with hepatocellular carcinoma. In addition, the study aimed to elucidate the effect of JPJD on the T cell receptor Vß-chain complementarity-determining region 3 (TCRVßCDR3) repertoire and the underlying mechanism. The FRL rat model was established by alternate-day food restriction and the oral administration of Glauber's salt (sodium sulfate), based on which the OHC model was then established. Subsequently, the FRL-OHC induced animals received JPJD or thymopentin-5 (TP5) for 17 days. Differences in the TCRVßCDR3 repertoire in the rat thymus, liver and hepatocellular carcinoma tissues were analyzed by polymerase chain reaction. Compared with the FRL-OHC model animals without any treatment, those treated with JPJD exhibited significantly inhibited hepatocellular carcinoma growth (P<0.05), reduced weight loss (P<0.01) and stable visceral indices (P<0.05). Furthermore, the JPJD treatment appeared to improve Simpsons diversity index (Ds) values and the quasi-Gaussian distribution rate of the TCRVßCDR3 repertoire in the thymus, liver and hepatocellular carcinoma tissues. However, no anti-hepatoma effects were evident in the rats treated with TP5. In addition, TP5 increased the Ds values and the quasi-Gaussian distribution rate of the TCRVßCDR3 repertoire in hepatocellular carcinoma tissues compared with those in the JPJD-treated group. The anti-hepatoma effects of JPJD in FRL-OHC-induced animals may be due to the promotion of the Ds values of the TCRVßCDR3 repertoire.

[Exploring the Correlation between Pi and Shen from the Excretion of AA-I and Expressions of Or- ganic Anion Transporting Polypeptide 2al and 2 b1 in Pi Deficiency Model Rats].

OBJECTIVE: To explore the correlation between Pi and Shen by observing the relationship between the metabolism of aristolochic acid (AA) and mRNA and protein expression levels of organic anion transporting polypeptide (oatp) superfamily member 2a1 and 2 b1 (oatp2al and oatp2bl) in renal, small intestinal, and large intestinal tissues of Pi deficiency syndrome (PDS) model rats. METHODS: Totally 46 Sprague-Dawley (SD) rats were randomly divided into four groups, i.e., the blank group (n = 12), the PDS group (n = 22), the AA-I group (n = 6), and the PDS AA-I group (n = 6). PDS model was established by subcutaneously injecting Reserpine at the daily dose of 5 mg/kg for 16 successive days. Carotid intubation was performed in 6 rats selected from the blank group and the PDS group. Pharmacokinetics of AA-I were detected at 5, 15, 30, 45, and 60 min after gastrogavage of AA-I. AA-I concentrations in renal, small intestinal, and large intestinal tissues of 10 rats selected from the PDS group were determined. Normal saline was administered to 6 rats selected from the PDS group and the blank group by gastrogavage. Renal, small intestinal, and large intestinal tissues were collected in the AA-I group and the PDS AA-I group at 60 min after gastrogavage of AA-I. mRNA and protein expression levels of oatp2a1 and oatp2b1 in each tissue were detected using real-time polymerase chain reaction (RT- PCR) and Western blot. RESULTS: Compared with the blank group, plasma concentrations of in vivo AA-I were obviously higher in the PDS group at 15, 30, 45, and 60 min after gastrogavage of AA-I with statistical difference (P < 0.05). Plasma concentrations of AA-I were obviously decreased at 60 min after gastrogavage of AA-I; AA-I concentrations in renal and large intestinal tissues were elevated; AA-I concentrations in small intestinal tissues were obviously reduced in the PDS group. There was no statistical difference in mRNA expression levels of oatp2a1 and oatp2b1 in the aforesaid three tissues of rats between the blank group and the PDS group. Compared with the blank group, mRNA expression levels of oatp2a1 and oatp2b1 decreased in small intestinal tissues of the AA-I group, and the mRNA expression level of oatp2a1 in large intestinal tissues significantly decreased (P < 0.05, P < 0.01). Compared with the PDS group, mRNA expression levels of oatp2a1 and oatp2b1 increased in renal tissues of the PDS AA-I group (P < 0.05); mRNA expression levels of oatp2b1 increased in large intestinal tissues of the PDS AA-I group (P < 0.05). CONCLUSIONS: The difference in AA-I metabolism might be associated with changed expression levels of oatp2a1 and oatp2b1 in renal, small intestinal, and large intestinal tissues under Pi deficiency induced loss of transportation. Shen and Dachang played important roles in substance metabolism under Pi deficiency state, which proved Pi-Shen correlated in Chinese medical theories.

[Clinical research on electrode and laser stimulating on acupoint combined with music therapy for grade 1 essential hypertension].

OBJECTIVE: To explore safe, effective, simple and easy non-drug treatments for grade 1 essential hypertension. METHODS: According to TCM syndrome differentiation, 126 cases of grade 1 essential hypertension were classified into 4 types: liver-fire hyperactivity syndrome, yin-deficiency and yang-hyperactivity syndrome, excessive phlegm-dampness syndrome, yin-yang deficiency syndrome, and then the patients were randomly divided into a photoelectric combined with musical treatment group (group A), an acupuncture group(group B) and a placebo group (group C). The acupoints were selected according to TCM syndrome differentiation in group A and group B, and multi-mode audio frequency pulse photoelectric therapeutic apparatus and acupuncture were used in the two groups respectively, once daily. Taichong (LR 3) and Quchi (LI 11) were selected in liver-fire hyperactivity syndrome, Taixi (KI 3) and Sanyinjiao (SP 6) were selected yi yin-deficiency and yang-hyperactivity syndrome, Zusanli (ST 36) and Fenglong (ST 40) were selected in excessive phlegm-dampness syndrome, while Taixi (KI 3) and Guanyuan (CV 4) were selected yi yirryang deficiency syndrome. The group C was treated with oral administration of starch tablet (25 mg), one tablet each time,three times everyday. Ten days were considered as one course, totally three courses were required in the three groups. The blood pressure and scores of TCM syndromes before and after treatment were compared among the three groups. RESULTS: The blood pressure decreased significantly after treatment in group A and group B (all P<0.01), and the decrease in systolic blood pressure was more significant in group A (P < 0.05). The total effective rate was 90.5 / (38/42) in group A, which was superior to 71. 4 (30/42, P < 0.05) in group B and 19.1% (18/34, P<0. 01) in group C. The scores of TCM syndromes were both improved in group A and group B, but without significant difference between the two groups (P > 0.05). CONCLUSION: The clinical effect of multi-mode audio frequency pulse photoelectric therapeutic apparatus for treatment of grade 1 essential hypertension is reliable. Meanwhile, it has the advantages of a non-invasive and simple operation.

Effect of polypeptide 2B1 on condition of dampness pattern in rats in terms of traditional Chinese medicine.

OBJECTIVE: This study investigated how polypeptide 2B1 is involved in regulating and governing dampness in rat models with dampness pattern defined in terms of Traditional Chinese Medicine. METHODS: We randomly divided 48 SPF 10-week-old male Sprague-Dawley (SD) rats into a normal group, normal + Aristolochic acid I (AA-I) for 5 min group, normal + AA-I for 60 min group, dampness pattern group (DS-Group), dampness pattern + AA-I for 5 min group, and dampness pattern + AA-I for 60 min group. Groups were then treated accordingly. We took out the lung, stomach, liver, spleen, kidney, large intestine, and small intestine tissues to detect gene and protein expression of organic anion transporter polypeptide 2B1 (OATP2B1). RESULTS: Gene expression of OATP2B1 in spleen, kidney, and small intestine of rats with dampness pattern was lower than that in normal rats (P < 0.05). The gene expressions of OATP2B1 in liver, stomach, large intestine, and small intestine were lower than that in control rats at different time points after being stimulated by AA-I (P < 0.05). CONCLUSION: There is coordination among multiple viscera in handling the condition of dampness, and the mechanism underlying the action may rely on regulating the expression of OATP2B1.
