The open-closed question of TCM theoretical system, which based on the ancient ideology, was always the core question which the scholars pestered. In four aspects: "the concept of yin-yang and wuxing——TCM methodology cornerstone, the TCM theory construction methodology, macroscopic judgment randomness of the human body pathology mechanism, the difficult problem of TCM theory extension",this article had analyzed this question and tried to elaborate it. The authors considered that TCM standed in the closed-like theoretical system of yin-yang and wuxing, the objective idealism speculation was its essential characteristics. TCM developed from this and kept its step originally also.

[Objective] To investigate the effect of Kun'an Granule (KG) on serum hormone level in rats with hyperprolactinemia [ Methods ] Rats were randomized to five groups: group A ( mimic operation) , group B (model control), group C (bromocriptine), group D (low-dose KG) and group E (high-dose KG). Except group A, the other four groups were implanted with pituitary for modeling. Group C was treated with bromocriptine 1 mg/kg, group D with gastric infusion of KG 4 g/kg and group E with KG 12 g/kg. The treatment lasted 34 days. Serum levels of prolactin (PRL), testosterone (T), follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estrogen (E2) were detected before and after treatment and the differences between groups were compared. [ Results ] Serum PRL and T levels were increased and LH, FSH and E2 levels decreased in group B (P

Objective To investigate the effects of the decoction of Huoxue Jiangtang Yin (HJY) combined with metformin on glucose and lipid metabolism and fat factors in type 2 diabetes patients with insulin resistance ( IR). Methods A total of 84 type 2 diabetes patients with IR were randomly assigned to experiment group and control group, 42 cases in each group. Both groups were given the basic treatment of controlling diet, exercise therapy, banning from smoking and alcohol, and psychological therapy. Additionally, the control group was given metformin orally, and the experiment group was given oral use of metformin and the decoction of HJY ( mainly composed of Radix Astragalie, Rhizoma Rehmanniae, Radix Salviae Miltiorrhizae, Radix Pseudostellariae, Fructus Schisandrae, Radix Ophiopogonis, Radix Dioscoreae, Rhizoma Polygonati, Cortex Moutan, Radix et Rhizoma Rhei, Flos Carthami, and Semen Persicae). The treatment for both groups covered 20 weeks for a course of treatment. Before and after the treatment, we observed the indexes of fasting plasma glucose (FPG), 2-h postprandial plasma glucose (2hPG), glycosylated hemoglobin (HbA1c), fasting insulin ( FINS) , homeostasis model assessment of insulin resistance ( HOMA-IR) , body mass index ( BMI) , blood lipid of total cholesterol ( TC) , triglyceride ( TG) and low density lipoprotein cholesterol ( LDL-C) , interleukin 6 ( IL -6) , tumor necrosis factor alpha ( TNF-α) , and secreted frizzled related protein 5 ( SFRP5). Results After treatment, FPG, 2hPG, HbA1c, BMI, FINS, TC, TG, LDL-C, HOMA-IR, TNF-α and IL -6 levels were all decreased (P<0.05 or P<0.01), and SFRP5 level was increased (P<0.05) in both groups compared with those before treatment. The improvement of the indexes in the experiment group was superior to that in the control group ( P<0.05 or P<0.01) Conclusion HJY combined with metformin has an effect on controlling body weight, regulating the glucose and lipid metabolism, and improving IR through regulating fat factors of IL-6, TNF-α and SFRP5 in type 2 diabetes patients with IR.

This article summarized the clinical experience of Professor WANG Meng-yong in treating chronic renal failure. The disease is mainly due to deficiency of lung, spleen, and kidney, and the Sanjiao dysfunction and water metabolism disorder of distribution, especially the spleen and kidney deficiency. Reinforcing pleen and kidney should be the basis in clinical syndromes; the superficial symptoms and root causes should be differentiated; the superficial symptoms should be treated if the patients have acute diseases; the root causes should be considered if the patients have chronic diseases; at the same time, the methods of tonifying qi and nourishing yin, protecting stomach qi, dredging intestines and descending turbid substance, invigorating the circulation of blood, and using diuretic of hydragogue to alleviate water retention should be applied, which can significantly improve symptoms of patients with chronic renal failure, delay the disease evolution process, and greatly improve life quality of patients.

To summarize the clinical experience of Professor WANG Meng-yong in the treatment of uric acid nephropathy. Professor WANG believes that the disease is mainly caused by spleen and kidney deficiency, disorder of function of Sanjiao, and pathological products, such as phlegm dampness and blood stasis and other metabolic disorders. Therefore, the treatment should distinguish symptoms and essence. Starting from pathogenesis and pathological features of spleen and kidney deficiency and phlegm dampness and blood stasis, the treatment should flexibly apply the methods of nourishing spleen and kidney, reducing phlegm and dispelling humidity, and activating blood and using diuretic of hydragogue to alleviate water retention, which can greatly reduce side effects caused by the long-term use of Western medicine and the onset of gout, and then to help disease recovery.

Objective Objective To evaluate the efficacy of Heqi San combined with metformin in the treatment of obese polycystic ovary syndrome (PCOS). Methods A total of 60 patients with obese polycystic ovary syndrome who met the inclusion criteria were randomly divided into 2 groups, 30 patients in each group. The control group was treated with metformin, and the treatment group was treated with Heqi San on the basis of the control group. Both groups were treated for 3 months. The FPG was determined by glucose oxidase method, and fasting insulin (FINS), TC, TG, LDL-C, HDL-C level were measured by radio immunoassay, and the insulin resistance index (IR) was measured by the method of HOMA-IR. The luteotropic hormone (LH), pro follicle stimulating hormone (FSH) and testosterone (T) were detected by the automatic electrochemical light detector, and the ratio of LH/FSH was calculated. The ovarian volume and body mass index changes and clinical effect were evaluated. Results After treatment, the BMI (20.09 ± 3.12 kg/cm2 vs. 23.39 ± 1.43 kg/cm2, t=6.889), FPG (4.44 ± 0.17 mmol/L vs. 4.74 ± 0.16 mmol/L, t=6.945), FINS (10.69 ± 2.41 IU/L vs. 16.29 ± 5.95 IU/L, t=4.778), TC (3.91 ± 0.50 mmol/L vs. 4.20 ± 0.39 mmol/L, t=2.505), LDL-C (2.64 ± 0.63 mmol/L vs. 3.18 ± 0.62 mmol/L, t=3.346), LH (8.70 ± 2.44 U/L vs. 10.27 ± 2.69 U/L, t=2.934), the ratio of LH/FSH (1.33 ± 0.58 vs. 2.18 ± 0.56, t=5.775), T (1.73 ± 0.74 nmol/L vs. 2.95 ± 1.10 nmol/L, t=5.040) and ovarian volume (12.61 ± 2.29 mm3 vs. 14.26 ± 2.52 mm3, t=6.982) in the treatment group were significantly lower than those in the control group (P<0.01 or P<0.05). The FSH (7.33 ± 2.28 U/L vs. 5.95 ± 1.20 U/L, t=2.934) in the treatment group were significantly higher than those in the control group (P<0.05). The total effective rate in the treatment group was 83.3% (25/30) and 63.3% (19/30) in the control group. The difference between the 2 groups was statistically significant (χ2=3.068, P=0.050). Conclusions The Heqi San combined with metformin can effectively improve the body mass index, glucose metabolism, lipid metabolism index and sex hormone level, and reduce the volume of ovary in patients with PCOS, and the curative effect is better than that of oral metformin alone.

Nonpharmaceutical interventions (NPIs) have been commonly deployed to prevent and control the spread of the coronavirus disease 2019 (COVID-19), resulting in a worldwide decline in influenza prevalence. However, the influenza risk in China warrants cautious assessment. We conducted a cross-sectional, seroepidemiological study in Shandong Province, Northern China in mid-2021. Hemagglutination inhibition was performed to test antibodies against four influenza vaccine strains. A combination of descriptive and meta-analyses was adopted to compare the seroprevalence of influenza antibodies before and during the COVID-19 pandemic. The overall seroprevalence values against A/H1N1pdm09, A/H3N2, B/Victoria, and B/Yamagata were 17.8% (95% CI 16.2%-19.5%), 23.5% (95% CI 21.7%-25.4%), 7.6% (95% CI 6.6%-8.7%), and 15.0 (95% CI 13.5%-16.5%), respectively, in the study period. The overall vaccination rate was extremely low (2.6%). Our results revealed that antibody titers in vaccinated participants were significantly higher than those in unvaccinated individuals (P < 0.001). Notably, the meta-analysis showed that antibodies against A/H1N1pdm09 and A/H3N2 were significantly low in adults after the COVID-19 pandemic (P < 0.01). Increasing vaccination rates and maintaining NPIs are recommended to prevent an elevated influenza risk in China.
