Serum Levels of Interleukin-1 Beta, Interleukin-6 and Melatonin over Summer and Winter in Kidney Deficiency Syndrome in Bizheng Rats

Objective To observe the seasonal changes in serum levels of interleukin-1 beta(IL-1β), interleukin-6(IL-6) and melatonin(MT) in Bizheng rat model, and explore the relationship between MT and the pathogenesis of rheumatoid arthritis. Methods One hundred and sixty Sprague-Dawley rats were randomly divided into four groups in summer(n=80) and winter(n=80) respectively: normal group, collagen-induced arthritis(CIA) model group, operation group, and sham-operation group(n=20 in each group). The CIA model group was injected with collagen emulsion at the base of the tail to induce arthritis. The rats in the operation group received pineal gland resection, and 7 days after the first operation, underwent testectomy or oophorectomy. The rats in the sham-operation group were operated to ligature the sagittal sinus, without extracting the pineal gland. After the operations, the operation group and the sham-operation group both were immunized as the CIA group was. The serum levels of IL-1β, IL-6 and MT in different groups were measured by radioimmunoassay. Results Compared with the normal group, the serum levels of IL-1β and IL-6 increased in the CIA model, operation, and sham-operation groups both in summer and in winter(IL-1β in summer, P=0.008, P<0.01, P=0.012; IL-1β in winter, P=0.019, P<0.01, P=0.027; IL-6 in summer, P=0.028, P<0.01, P=0.024; IL-6 in winter, P=0.006, P<0.01, P=0.008). In the operation group, the serum levels of IL-1β and IL-6 in winter were higher than in summer, but with no statistically significant differences(P=0.844, 0.679). Compared with the normal group, the serum level of MT significantly increased in summer and winter in both the CIA model group(P=0.002, 0.008) and the sham-operation group(P=0.003, 0.007), while significantly decreased in the operation group(P=0.023, 0.003). There was no significant difference in MT level in the operation group between summer and winter(P=0.947). Conclusions The increase of serum levels of IL-1β and IL-6 may exacerbate the inflammatoryreaction and cause a more severe condition in the rheumatoid arthritis. The concentrations of IL-1β, IL-6, and MT correspond with the change of seasons, confirming that there are connections between nature and human body.

Age-related changes in prevalence and symptom characteristics in kidney deficiency syndrome with varied health status:a cross-sectional observational study

Objective:This study aimed to reveal the age-related changes in prevalence and symptom characteristics in kidney deficiency syndrome(KDS)with varied health status.Methods:This cross-sectional observational study was conducted in6 hospitals.Investigators queried participants aged 20e79 about their health,including symptoms if any,and completed questionnaires to collect participants responses.Prevalence,severity,and frequency of KDS and other relevant parameters were observed and recorded.Comparative analysis of countable variables,including prevalence,was performed by frequency analysis and c2 test and expressed as a composite ratio.Comparative analysis of quantitative scores of the severity and frequency of symptoms was performed by the rank-sum test.Regression analysis of the correlation of KDS with potential contributing factors was performed by non-conditional binary logistic stepwise regression of numerical variables.Results:Prevalence of KDS in healthy and unhealthy participants correlated with increasing age(P<0.05).In those with chronic disease,KDS prevalence was comparatively high,but the trend was not obvious.KDS prevalence in participants age 20e39 showed an increasing trend with deteriorating health(P<0.05).Compared to healthy individuals,KDS prevalence in subhealthy persons and those with chronic disease showed an increasing trend(P<0.05)in the 40e59 and 60e79 age groups,whereas there was no difference between subhealthy persons and those with chronic disease age 40e59 and 60e79.Symptom severity scores of KDS showed an increasing trend with increasing age and deteriorating health status(P<0.05).Higher symptom frequency scores were also positively correlated with increasing age(P<0.05),but health status deterioration was not significantly correlated(P>0.05).Age,health status,lower back pain,shin soreness or heel pain,tinnitus or deafness,hair loss or loose teeth,incomplete bladder emptying or incontinence,and sexual dysfunction or infertility were potential factors contributing to KDS(P<0.05),but age was the only independent variable for which OR>1.Moreover,the distribution of typical KDS-related symptoms showed dramatic regularities.Conclusion:Prevalence and symptom characteristics of KDS were found to increase consistently with increasing age and deteriorating health status.Kidney deficiency may be an important mechanism of aging in the subhealthy and chronic disease states.

Preventive online and offline health management intervention in polycystic ovary syndrome

BACKGROUND Polycystic ovary syndrome(PCOS) is characterized by hyperandrogenism, hyperinsulinemia, ovarian polycystic changes, and irregular ovulation, often occurring in women of childbearing age for whom it can be a cause of infertility. Hypothalamus-pituitary-ovarian axis dysregulation is important in the pathogenesis of PCOS and the associated chronic excess of sex hormones can lead to cardiovascular and cerebrovascular diseases, diabetes, and malignancies such as endometrial cancer, and breast cancer. At present, most scholars agree that lifestyle interventions in conjunction with drug treatment can help PCOS patients achieve their goals of successful pregnancy and childbirth.AIM To investigate the clinical effect of an online and offline(O2O) preventive health management model on PCOS with kidney deficiency and phlegm dampness.METHODS A total of 82 patients with PCOS of the kidney deficiency and phlegm dampness type who were admitted to Beijing Luhe Hospital Affiliated to Capital Medical University from April 2019 to June 2020 were randomly divided into two groups. The treatment group was treated with oral Diane-35 for 3 mo and received preventive O2O medical health management for 6 mo(including eating and living, exercise, drug management). The control group was treated with oral Diane-35 for 3 mo and completed outpatient health education. The traditional Chinese medicine(TCM) syndrome score, acne score, hair score, sex hormone level and clinical effects were compared between the two groups before and after the intervention. RESULTS After treatment, the TCM syndrome score, acne score, and serum luteinizing hormone/follicle stimulating hormone level were significantly lower in the treatment group than in the control group(P < 0.05). After 3 mo of treatment, the TCM syndrome curative effect index in the treatment group was 97.30% compared to 54.05% in the control group(P < 0.05), whereas the total treatment effect in the treatment group was 91.89%, compared to 54.05% in the control group(P < 0.05).CONCLUSION An integrated therapeutic approach incorporating medication, TCM methods and social media is more effective than standard treatment for PCOS.

Clinical treatment of myasthenia gravis with deficiency of spleen and kidney based on combination of disease with syndrome theory

OBJECTIVE: To study the use of Jianjining in the treatment of myasthenia gravis (MG) patients with a deficiency of both spleen and kidney via the theory on the combination of disease with syndrome. METHODS: Sixty MG patients with a deficiency of both spleen and kidney were randomly divided into an treatment group (n=30) treated with Jianjining granules and Western Medicine (prednisone or pyridostigmine bromide) and a control group (n= 30) treated with Jianjining granules. The dosage of the three drugs was reduced over the course of treatment. After 3 and 6 months of treatment, the curative effect was evaluated with the muscle weakness severity scale (MWSS). RESULTS: The MWSS score after treatment declined significantly in both groups. The score in the treatment group was much lower than that in thecontrol group (P<0.05). The total effective rate was 63.33% (19/30) in the treatment group and 36.67% (11/30) in the control group after 3 months of treatment, and 80.00% (24/30) and 50.00% (15/30), respectively, after 6 months of treatment. The obvious and total effective rates in the treatment group were much higher than those in the control group (P<0.05). After 6 months of treatment, there were no obvious differences (P>0.05) in the obvious and effective rates between the 2 groups. However, the total effective rate in the treatment group was much higher than that in the control group (P<0.01). CONCLUSION: Using the theory on the combination of disease with syndrome, we found that the curative effect of Jianjining and Western Medicine on MG patients with deficiency of both spleen and kidney is worth further exploration.

The Effect of Hormones of the Hypothalamic-pituitary-target Gland Axes in a Kidney-Yang Deficiency Syndrome Model

Kidney-yang deficiency syndrome(KYDS)is a diagnostic pattern in the traditional Chinese medicine.Studies have shown that KYDS is related to the functional disorder of hormones of the hypothalamic-pituitary-target gland axes.The standard procedure used to mimic KYDS is the injection of a high dose of exogenous glucocorticoid(hydrocortisone and corticosterone).Such a model showed symptoms such as exhaustion,body twists,cold limbs,lying crowded together,decreased rectal temperature,sexual dysfunction,decreased reaction speed,reduced spontaneous activity,hair loss,loss of appetite,and weight loss.Moreover,the model manifested an imbalance in mutual control among the hormones of the pituitary-target gland axes,including adrenocorticotrophic hormone,CORT,CRH,thyroid-stimulating hormone,triiodothyronine,thyroxine,T,E2,follicle-stimulating hormone,luteinizing hormone,and 17-OHCS.

The Fourier Transform Infrared Spectra of the Key Organs Derived from Kidney(Shen)-Yang Deficiency Syndrome Mice

Objective：To explore an approach to rapidly and accurately identify the compounds as biomarkers of Chinese medicine（CM）syndromes.Method：The Fourier transform infrared（FT-IR）spectrometry was applied to investigate the characteristic components of a mice model of Kidney（Shen）-yang deficiency syndrome（KDS）,and the remedial effect of a typical CM formula Shenqi Pill（肾气丸）.Thirty-six females and 18 males of Balb/c mice were randomly divided into KDS,Shenqi or control group.The females and males of the same group freely were mated for 96 h,and the males were taken out and only the female mice were raised.Females of the KDS group were threatened by a ferocious cat every other day for 14 d.After delivery,the KDS,or gestational threatened,offspring were raised at standard condition for 11 weeks.Then 10 male offspring were randomly selected,anaesthetized and their representative organs,i.e.testes,kidneys,lungs and feet were collected,for the FT-IR scan.Mice of the Shenqi group were intragastric administered Shenqi Pill;while mice in the KDS and control groups were given the same volume of saline.Results：The attenuated birth outcomes of the KDS group were displayed.The remarkable FT-IR differences of all organs between KDS mice and healthy control were mainly at 1,735-1,745 cm-1（indicating the increased levels of lipids）and at 1,640-1,647 cm-1and 1,539-1,544 cm-1（displaying the decreased proteins）.No statistic FT-IR difference between Shenqi and control mice was observed.Conclusion：In accordance with major traits of KDS,prenatal stress extensively impaired the building up of proteins and resulting in the excessive lipid storage,and FT-IR could effectively identify the biomarkers of KDS.

Shen(Kidney)-Tonifying Principle for Primary Osteoporosis:to Treat Both the Disease and the Chinese Medicine Syndrome

Primary osteoporosis （POP） is one of the most common diseases in the elderly people resulting in high risk of fracture and poor quality of life. In addition to the pathological changes in bone mass, most of the POP patients also suffer from Chinese medicine （CM） syndromes of Shen （Kidney） essence deficiency. Shen essences are highly related to bone. Shen essence deficiency plays an important part in the development of POP and a better diagnosis of POP could be made by combining CM syndromes with Western medicine risk factors. Treatments of POP should aim at both increasing the bone mass and relieving the syndromes of Shen essence deficiency. Clinical study confirmed that treating POP patients with Shen-tonifying herbs could increase the bone mass and relieve the CM syndromes of POP patients. Basic researches clarified the mechanism by which Shen-tonifying herbs increased bone mass in animal models. The mechanisms by which Shentonifying herbs relieve the CM syndromes are still in investigation.

Study on Molecular Mechanism of Liver Yang Ascending Syndrome in Hypertension

Objective: To investigate the molecular mechanism of Liver Yang Ascending Syndrome (LYAS) in hypertension. Methods: The plasma norepinephrine (NE), epinephrine (E) contents in patients with LYAS or Liver and Kidney Yin Deficiency Syndrome (LKYDS) of hypertension and normal controls were determined by high performance liquid chromatography-electrochemical detector (HPLC-ECD). The polymorphism of tyrosine hydroxylase (TH) gene in the three groups were analysed by Southern Blot assay. The polymorphism of TH and monoamine oxidation A(MAO-A), monoamine oxidation B(MAO-B) gene microsatellite in these groups were analysed by polymerase chain reaction (PCR)-SSCP. At the same time, the LYAS model was established by administering Aconitum preparation (AP) to spontaneous hypertension rats (SHR). The adrenal gland medulla of the experimental animal was examined for their TH expression at the protein level after ABC immuno-histochemical staining with the TH monoclonal antibody (McAb). The adrenal TH gene mRNA expression was demonstrated by in situ hybridization with the synthetized TH oligonucleic acid probe. The results of immuno-histochemistry and in situ hybridization were analyzed with the image analysis system (IAS). Results: The plasma NE and E contents in patients with LYAS were more obviously increased than those in LKYDS and normal controls. The TH gene amplified and the type A1 TH microsatellite D11S4046 was markedly higher in the LYAS group than those in the other groups. The TH mRNA protein expression in the adrenal tissue of the AP induced LYAS model in SHR elevated. Conclusion: The LYAS of hypertension has the characters as amplified TH gene and increased TH mRNA and protein expression, which suggested that the overexpression of TH is probably the mechanism of LYAS in hypertension.
