Cardiac fibrosis(CF) is a cardiac pathological process characterized by excessive deposition of extracellular matrix(ECM). When the heart is damaged by adverse stimuli, cardiac fibroblasts are activated and secrete a large amount of ECM, leading to changes in cardiac fibrosis, myocardial stiffness, and cardiac function declines and accelerating the development of heart failure. There is a close relationship between heart yin deficiency and cardiac fibrosis, which have similar pathogenic mechanisms. Heart Yin deficiency, characterized by insufficient Yin fluids, causes the heart to lose its nourishing function, which acts as the initiating factor for myocardial dystrophy. The deficiency of body fluids leads to stagnation of blood flow, resulting in blood stasis and water retention. Blood stasis and water retention accumulate in the heart, which aligns with the pathological manifestation of excessive deposition of ECM, as a tangible pathogenic factor. This is an inevitable stage of the disease process. The lingering of blood stasis combined with water retention eventually leads to the generation of heat and toxins, triggering inflammatory responses similar to heat toxins, which continuously stimulate the heart and cause the ultimate outcome of CF. Considering the syndrome of heart Yin deficiency, traditional Chinese medicine capable of nourishing Yin, activating blood, and promoting urination can reduce myocardial cell apoptosis, inhibit fibroblast activation, and lower the inflammation level, showing significant advantages in combating CF.

OBJECTIVESTo investigate the mechanism of Liuwei Dihuang Pill (, LDP) in treating postmenopausal osteoporosis (PMOP) with Shen (Kidney) yin deficiency.

METHODSIn this study, 205 cases of PMOP were divided into the PMOP Shen-yin deficiency group (Group A), PMOP Shen-yang deficiency group (Group B), PMOP without Shen deficiency group (Group C), and control group (Group N). Real-time polymerase chain reaction (RT-PCR) and Western blot techniques were used to observe the effects of LDP treatment on the cardiotrophin-like cytokine factor 1 (CLCF1), ankyrin repeat and SOCS box containing 1 (ASB1), and prokineticin 2 (PROK2) genes and the Janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling pathway.

RESULTSThe mRNA (P<0.05) and protein (P<0.01) expression levels of the CLCF1 gene in Group A were significantly lower than the corresponding levels in Group N. After LDP treatment for 3 months, the mRNA expression levels of the CLCF1 gene were obviously up-regulated (P<0.01). After 6-month treatment, the expression levels of CLCF1 mRNA and protein were significantly up-regulated (both P<0.01), and the average bone density of the top femur had significantly increased (P<0.05). In vitro, CLCF1 overexpression resulted in a significant increase in the total protein and phosphorylated protein levels of JAK2 and STAT3.

CONCLUSIONSThe CLCF1 gene is an important gene associated with PMOP Shen-yin deficiency and the therapeutic effects of LDP may be mediated by up-regulation of CLCF1 gene expression and activation of the JAK/STAT signaling pathway.

Objective: To investigate the expression of the G-protein coupled estrogen receptor (GPER) in the testis of the male mouse with kidney yin or kidney yang deficiency and its influence on the reproductive function of the mouse. METHODS: We randomized 30 six-week-old male Kunming mice into three groups of equal number: kidney yang deficiency, kidney yin deficiency, and normal control, and established the models of kidney yang deficiency and kidney yin deficiency by peritoneal injection of hydrocortisone at 50 mg/kg for 5 days and 25 mg/kg for 10 days, respectively. We observed the behavioral changes of the mice using the elevated plus-maze, exhaustive swimming and field experiment, examined the semen quality with the automatic sperm quality analyzer, calculated the average number of the offspring, measured the serum testosterone (T) and estradiol (E2) levels and T/E2 ratio by Roche electrochemiluminescence assay, and determined the localization and expression of GPER in the testis by immunohistochemistry and immunofluorescence staining. RESULTS: Compared with the mice with kidney yin deficiency, those with kidney yang deficiency showed remarkably fewer entries into the open arm and central area (P <0.05) and shorter time of exhaustive swimming (P <0.05), but no statistically significant difference in the time spent in the open arm or the central area (P >0.05); the latter group also exhibited significant decreases in the epididymal sperm count (［7.27 ± 1.30］ vs ［3.05 ± 1.06］ ×108/g, P <0.01), sperm motility (［54.15 ± 13.52］ vs ［51.57 ± 8.75］ %, P <0.01) and average number of the offspring (6.46 vs 4.33, P <0.05), a slight increase in the rate of morphologically abnormal sperm (［13.42 ± 2.32］ vs ［15.39 ± 2.48］ %, P >0.05), and markedly reduced serum T (［24.96 ± 6.18］ vs ［16.72 ± 5.92］ ng/dl,P <0.05), E2 (［19.81 ± 4.01］ vs ［15.24 ± 1.11］ pg/ml,P <0.05) and T/E2 ratio (1.41 vs 1.25, P <0.05). The expression of GPER was found in the cytoplasm of the Leydig cells, negative in the nuclei and cell membrane, significantly higher in the kidney yang than in the kidney yin deficiency group (P <0.05). CONCLUSIONS The numbers of sperm and offspring decreased while the percentage of morphologically abnormal sperm increased in both the kidney yang and kidney yin deficiency mice, even more significantly in the former, which might be associated with the up-regulated expression of GPER in the testis of the mouse with kidney yang deficiency and consequently the reduced serum T level and T/E2 ratio.

Recent studies have revealed that the property of drug is mainly associated with the body's substance and energy metabolism. The present study aimed to evaluate the drug property of Poria, called Fuling (FL) in traditional Chinese medicine (TCM), in terms of its effects on the substance and energy metabolism in rat models of cold-deficiency and heat-deficiency syndromes, compared with Aconiti Lateralis Radix Praeparaia, called Fuzi (FZ) in TCM, with hot property, and Anemarrhenae Rhizoma, called Zhimu (ZM) in TCM, with cold property, as reference drugs, respectively. The appearance score, toe and rectal temperatures of the animals treated were assessed at different time points. Several indices in vivo correlated with substance and energy metabolism (glucokinas, phosphoglycerate kinase, cytochrome c reductase, cytochrome c oxydase, and Na-K-ATPase), endocrine system (triiodothyronine, thyroxine, and 17-hydroxycorticosteroid), nervous system (acetylcholin esterase), and cyclic nucleotide system were determined. The changes in appearance score and indices in vivo suggested the successful establishment of cold-deficiency and heat-deficiency syndrome models. FZ reversed the decreased levels of indices (substance and energy metabolism and endocrine system) and alleviated the syndrome of cold-deficiency model, and ZM showed obviously therapeutic effect on heat-deficiency syndrome (appearance score, substance and energy metabolism, and endocrine system). FL could alleviate cold-deficiency syndrome and raise the decreased levels of glucokinas, phosphoglycerate kinase, cytochrome c reductase and triiodothyronine in cold-deficiency model, but had no significant effect on heat-deficiency syndrome. Drug property of FL was inferred as trending to "flat and warm", which still need further study. It was advisable to adopt both cold-deficiency and heat-deficiency models to study the drugs with "flat" property.

Some unhealthy life habits, such as long-term smoking, heavy drinking, sexual overstrain and frequent stay-up could induce the Yin deficiency symptoms of zygomatic red and dysphoria. Stems of Dendrobii officinalis flos (DOF) showed the efficacy of nourishing Yin. In this study, the hyperthyroidism Yin deficiency model was set up to study the yin nourishing effect and action mechanism of DOF, in order to provide the pharmacological basis for developing DOF resources and decreasing resource wastes. ICR mice were divided into five groups: the normal control group, the model control group, the positive control group and DOF extract groups (6.4 g · kg(-1)). Except for the normal group, the other groups were administrated with thyroxine for 30 d to set up the hyperthyroidism yin deficiency model. At the same time, the other groups were administrated with the corresponding drugs for 30 d. After administration for 4 weeks, the signs (facial temperature, pain domain, heart rate and autonomic activity) in mice were measured, and the facial and ear micro-circulation blood flow were detected by laser Doppler technology. After the last administration, all mice were fasted for 12 hours, blood were collected from their orbits, and serum were separated to detect AST, ALT, TG and TP by the automatic biochemistry analyzer and test T3, T4 and TSH levels by ELISA. (1) Compared with the normal control group, the model control group showed significant increases in facial and ear micro-circulation blood flow, facial temperature and heart rate (P < 0.05, P < 0.01), serum AST, ALT (P < 0.01), T3 level (P < 0.05), TSH level (P < 0.05) and notable deceases in pain domain (P < 0.01), TG level (P < 0.01). (2) Compared with the model control group, extracts from DOF (6 g · kg(-1)) could notably reduce facial and ear micro-circulation blood flow, facial temperature and heart rate (P < 0.05, P < 0.01) and AST (P < 0.05) and enhance pain domain (P < 0.01) and TG (P < 0.01). Extracts from DOF (4 g · kg(-1)) could remarkably reduce AST and ALT levels (P < 0.01, 0.05). Extracts from DOF (6 g · kg(-1) 4 g · kg(-1)) could significantly reduce T3 and increase serum TSH level (P < 0.05). DOF could improve Yin deficiency symptoms of zygomatic red and dysphoria in mice as well as liver function injury caused by overactive thyroid axis. According to its action mechanism, DOF may show yin nourishing and hepatic protective effects by impacting thyroxin substance metabolism, improving micro-circulation and reducing heart rate.

OBJECTIVETo explore the correlation between the HLA-DR13, basic core promoter (BCP), changes of T lymphocyte subset and clinical Chinese medical syndromes of chronic hepatitis B (CHB).

METHODSTotally 102 CHB patients were syndrome typed as Gan depression Pi deficiency syndrome (GDPDS), Pi-Shen yang deficiency syndrome (PSYDS), Gan-gallbladder dampness heat syndrome (GGDHS), Gan-Shen yin deficiency syndrome (GSYDS), and static blood blocking collaterals syndrome (SBBCS). Besides, 30 healthy subjects were recruited as the normal control group. The blood HBV-DNA level and HLA-DR13 gene were detected with real time fluorescent PCR. The expression of CD4+ and CD8+ in T lymphocytes was detected using flow cytometry. The mutation of serum A1762T/G1764A was detected using PCR sequencing. Hepatitis Be antigen (HBeAg) was detected with ELISA, and correlation between various Chinese medical syndrome types and objective indicators were analyzed.

RESULTSThere was no statistical difference in HBV-DNA quantitative results among various syndrome types (P > 0.05). HBeAg positive rate was higher in GDPDS than in other syndrome types (P < 0.05). It was sequenced as GDPDS > GSYDS > SBBCS > GGDHS > PSYDS. Compared with the normal control group, percentages of CD3+ and CD3+ CD4+ were lower in PSYDS (P < 0.05). The ratio of CD3+ CD4+/CD3+ CD8 was lower in GGDHS and PSYDS than in the normal control group (P < 0.05). There was no statistical difference in the CD3+ CD8+ percentage among various syndrome types (P > 0.05). The quantitation of HLA-DR13 gene was lower in GDPDS and GSYDS than in the normal control group (P < 0.05). The positive rate of BCP mutation was higher in GSYDS than in other syndrome types (P < 0.05).

CONCLUSIONCo-detection results of HLA-DR13 and BCP could be used as reference indices of Chinese medical syndrome typing of CHB.

OBJECTIVETo explore the laws of anovulatory infertility patients of Gan-yin deficiency syndrome (GYDS), and to analyze the correlation between GYDS and partial sex hormones and metabolic parameters.

METHODSRecruited were 103 anovulatory infertility patients, including 48 of GYDS and 55 of non-GYDS. At the same time, 20 healthy pluripara at the child-bearing period were recruited as the control group. The body mass index (BMI) and waist to hip ratio (WHR) were measured. Serum levels of luteinizing hormone (LH), follicle stimulating hormone (FSH), testosterone (T), prolactin (PRL), estradiol (E2), sex hormone binding globulin (SHBG), fasting blood glucose (FBG), fasting insulin (FINS), total cholesterol (TC), triglyceride (TG), low density lipoprotein-cholesterol (LDL-C), high density lipoprotein-cholesterol (HDL-C), and leptin were detected. The inter-group difference of the above indices was compared between the two groups.

RESULTSLevels of BMI, FINS, HOMA-IRI, leptin, TC, TG, LDL-C, T, PRL, and LH were higher in the GYDS group and the non-GDS group than in the control group (P < 0.01, P < 0.05), while SHBG was lower in the GYDS group and the non-GYDS group than in the control group (P < 0.01). Only the PRL level was higher in the GYDS group than in the non-GYDS group (P < 0.01).

CONCLUSIONSGan-yin deficiency is a predominant manifestation in anovulatory infertility patients. Partial disorder of some sex hormones and metabolic derangement might be common pathological factors for anovulatory infertility, while increased PRL levels was dominant in GYDS.

OBJECTIVETo explore the clinical efficacy and mechanism of acupuncture and tapping therapy in the treatment of type 2 diabetes of yin deficiency pattern combined with stasis in the patients.

METHODSOne hundred and twelve patients were treated with acupuncture, followed by tapping method. The reinforcing method with lifting, thrusting and rotating needle technique was used at Taixi (KI 3), Shenmen (HT 7), Taibai (SP 3), Taiyuan (LU 9), Sanyinjiao (SP 6) and Zusanli (ST 36); and the even-needling technique was used at Taichong (LR 3), Hegu (LI 4), Xuehai (SP 10) and Fenglong (ST 40). The needles were remained for 30 min. After needle removal, the tapping method with plum-blossom needle was applied to Geshu (BL 17), Yishu (EX-B 3), Ganshu (BL 18), Shenshu (BL 23) and Pishu (BL 20), once every two days. The treatment of 3 months was required. The changes were observed before and after treatment in the relevant indices of fat-islet axis such as fasting plasma glucose (FPG), fasting leptin (FLP), fasting insulin (FINS), insulin sensitivity index (ISI), insulin resistance (Homa IR), insulin secretion index (Homa-beta) and the indices of obesity and blood lipids in the patients.

RESULTSAfter treatment, the total effective rate was 84.8% (95/112), in which the efficacy on the stasis predominated syndrome was better than that of yin deficiency predominated syndrome [92.9% (52/56) vs 76.8% (43/56), P < 0.05]. Before treatment, FPG, FLP, FINS, Homa-IR, total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), body mass, body mass index (BMI), fat percentage (F%) and obesity degree in the patients were higher obviously than those in the normal group (all P < 0.01); high-density lipoprotein cholesterol (HDL-C) and ISI were lower than those in the normal group (both P < 0.01). After treatment, FPG, FLP, FINS, Homa-IR, TC, TG, LDL-C, body mass, BMI, F% and obesity degree were all reduced obviously as compared with those before treatment (all P < 0.01). ISI and HDL-C were increased apparently (both P < 0.01). The efficacy on mild obesity was superior to that on moderate and severe obesity, and the efficacy in the young patients was better than that in the elderly, the efficacy in the males was better than that in the females, but the differences were not significant (all P > 0.05). The efficacy in the cases with 10 years duration of sickness was superior to those with over 10 years duration of sickness (P < 0. 01).

CONCLUSIONAcupuncture and tapping therapy achieves the significant efficacy on type 2 diabetes of yin deficiency pattern combined with stasis and its effect mechanism is related to the positive regulation of glucose, lipid metabolism and fat-islet axis.

OBJECTIVETo observe the effects of Liuwei Dihuang Granule ([symbols; see text], LDG) for tonifying Kidney (Shen) on the outcomes of in vitro fertilization pre-embryo transfer (IVF-ET) of infertility women with Kidney-yin deficiency syndrome and to explore its mechanism by detecting the proteome expression in the follicular fluid.

METHODSSixty-six infertility patients of Kidney-yin deficiency syndrome who would undergo IVF-ET, were randomly assigned to a treatment group and a control group according to a random number table, 33 cases in each group. Another 33 cases of non-Kidney-yin deficiency syndrome was taken as a syndrome-control group. Besides Western routine therapy, LDG was given 3 menstrual cycles before IVF to the treatment group, and a placebo granule to the control and syndrome-control groups. The scores of Kidney-yin deficiency symptoms (sore waist and knees, dry vagina, dysphoria with feverish sensation in the chest, palms and soles, etc.) were assessed, the number of retrieved oocytes, rates of high quality oocytes and embryos, fertility rate and clinical pregnancy rate were recorded, and the follicular fluid was collected on the day when the ovum was picked up, the differential protein expression was detected using two-dimensional gel electrophoresis, and then, matrix assisted laser desorption ionization time-of flight mass spectrometry (MALDI-TOF-MS) was applied to identify the proteins.

RESULTSThe syndrome score in the treatment group decreased significantly from 16.09±2.58 to 8.67±2.13, while it changed insignificantly in the control group, with a significant difference in the lowering score between the two groups (P<0.05); the high quality rates of oocytes and embryos and clinical pregnancy rate were all superior in the treatment group to the control group (82.29% vs 78.08%, 76.76% vs 68.79%, 63.64% vs 36.36%, all P<0.05). The protein expression map from the follicular fluid showed that compared with the control group, 33 differential protein expressions were found in the syndrome-control group, among which 18 were down-regulated, and 15 up-regulated; in the treatment group 28 differential protein expressions were found, among which 15 were down-regulated, and 13 up-regulated. Through MALDI-TOF-MS, 14 proteins were identified (P<0.05).

CONCLUSIONSFor the infertility patients undergoing IVF, LDG could alleviate clinical symptoms, improve rates of high quality oocytes and embryos, so as to raise clinical pregnancy rate. The mechanism may be through regulating proteome expression in the follicular fluid to improve the developmental microenvironment for oocytes which would lead to a successful embryo implantation.

OBJECTIVETo observe the effects of Jinshuibao Capsule (JC) combined losartan potassium on some indices of early renal damage of hypertension patients of yin and yang deficiency syndrome (YYDS), such as levels of serum cystatin C (Cys C), beta2-microglobulin (beta2-MG), hypersensitive C-reactive protein (hs-CRP), uric acid (UA), blood pressure, blood lipids, and fasting blood glucose (FBG), and to explore their protective effects on early renal damage of hypertension patients and on the metabolisms of blood lipids and blood glucose.

METHODSTotally 106 hypertension patients of YYDS were randomly assigned to two groups, 53 patients in the control group (treated by losartan potassium) and 53 patients in the treatment group (treated by JC + losartan potassium). The treatment lasted for 16 weeks. The serum changes of UA, Cys C, beta2-MG, hs-CRP, blood lipids [including total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C), and high density lipoprotein cholesterol (HDL-C)], and FBG levels were measured to evaluate the renal protective effects and to assess their effect on the metabolisms of blood lipids and blood glucose.

RESULTSCompared with before treatment in the same group, the systolic blood pressure (SBP) decreased in the two groups after treatment, showing statistical difference (P < 0.05, P < 0.01), but there was no statistical difference between the two groups (P > 0.05). The diastolic blood pressure (DBP) was not obviously declined in the two groups after treatment, showing no statistical difference. Compared with before treatment in the same group, the LDL-C level decreased obviously after treatment in the control group. But there was no obvious change in FBG, TC, HDL-C, and TG in the control group, showing no statistical difference when compared with before treatment (P < 0.05). The FBG, TC, and LDL-C obviously decreased in the treatment group more obviously after treatment than before treatment, showing statistical difference (P < 0.05, P < 0.01). There was no statistical difference when compared with the control group after treatment (P > 0.05). Compared with before treatment in the same group, the levels of UA, Cys C, beta2-MG, and hs-CRP all decreased in the two groups, showing statistical difference (P < 0.05, P < 0.01). The SCr level decreased in the treatment group more obviously after treatment than before treatment, showing statistical difference (P < 0.05). Compared with the control group after treatment, the levels of Cys C, beta2-MG, and hs-CRP decreased more obviously after treatment in the treatment group, showing statistical difference (P < 0.05).

CONCLUSIONSJC combined losartan potassium showed better effects in treating early renal damage of hypertension patients of YYDS. They could protect and stabilize the renal functions more effectively. JC could regulate blood lipids and blood glucose.
