ABSTRACT

Objective:Exploratory study on the relationship between TCM syndrome types, TCM constitution and clinical symptoms of idiopathic central precocious puberty children and rapidly progressive early development children in Shanghai, so as to provide a basis for early intervention and syndrome differentiation and treatment.Methods:A cross-sectional study and retrospectively enrolled. Through questionnaire survey, the basic information, clinical symptoms and TCM constitution of children diagnosed with idiopathic central precocious puberty and rapidly progressive early development were collected from the Pediatric Endocrinology Clinic of Affiliated Shuguang Hospital of Shanghai University of Traditional Chinese Medicine from July to August 2022, and the correlation between the distribution, differentiation and clinical symptoms of TCM constitution in children with idiopathic central precocious puberty and children with rapidly progressive precocious puberty in Shanghai were explored through data analysis.Results:① Fast progressive early development children with higher BMI and age than idiopathic central precocious puberty were statistically significant ( P<0.05), and no significant difference in the sex composition ratio between the two groups. ② Among children with idiopathic central precocious puberty and children with rapid progressive early development, the proportion of liver depression fire syndrome was the highest, 59.15% (42/71) and 46.51% (60/129) respectively, and the proportion of Qi depression was the highest, 35.21% (25/71) and 36.43% (47/129) respectively. However, there was no significant difference in the TCM syndrome types and physical distribution of the two groups. ③ The TCM syndrome types of 200 precocious children weres correlated with physical distribution, among which Yin deficiency fire flourishing syndrome was significantly associated with Yin deficiency, liver stagnation fire syndrome was significantly correlated with qi depression, and phlegm dampness obstruction syndrome was significantly correlated with phlegm dampness and Yang deficiency ( P<0.01). ④ A total of 200 children with precocious puberty were more female than male, male BMI was higher than female, and the BMI of children with precocious puberty was higher than other syndrome types, and the differences were statistically significant ( P<0.01). Liver stasis fire syndrome was the highest proportion between boys and girls, but there was no obvious difference in TCM syndrome types between different genders. The highest proportion of breast pain in clinical symptoms was 22.19% (69/311). Conclusion:Children with idiopathic central precocious puberty and rapidly progressive early development children have differences in age and BMI, with no obvious difference in gender composition, TCM syndrome type and physical distribution, but there is a correlation between TCM syndrome type and physical constitution of precocious puberty children.

ABSTRACT

Objective:To investigate the mechanism of levosimendan on acute kidney injury after cardiopulmonary resuscitation (CPR) in rats.Methods:Twenty-five healthy adult male SD rats were randomly divided into three groups: control group ( n=5), levosimendan group ( n=10) and experimental group ( n=10). A cardiac arrest-cardiopulmonary resuscitation model was established using smothering method in the experimental group and levosimendan group. The levosimendan group was treated with levosimandan during and after resuscitation, while the experimental group was given equivalent volume of saline solution during and after resuscitation, and the control group was only given equivalent volume of saline without performance of CPR. The rats in the three groups were sacrificed at 6 h after resuscitation. The serum and kidney tissue samples were collected. Serum biochemical indicators [serum creatinine (Scr), blood urea nitrogen (Bun), interleukin-1β (IL-1β), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α)] were measured. HE staining and Paller score were used to identify the degree of kidney damage. Apoptosis was estimated by TUNEL staining. Western blot was used to detect the expression levels of phosphorylation of extracellular regulated protein kinases (p-ERK). One-way analysis of variance was used to compare the mean values of normally distributed measurement data between groups. Comparisons between groups were performed using the least significant difference t-test. Results:Scr (85.02±1.31) μmol/L, Bun (7.36±0.13) mmol/L, Paller score (7.3±0.2), IL-1β (302.20±17.35) pg/mL, IL-6 (564.60±23.24) pg/mL and TNF-α (1346±83.73) pg/mL in the experimental group were significantly higher than those of the control group [(15.94±0.96) μmol/L, (2.95±0.18) mmol/L, (0.7±0.2), (7.27±0.44) pg/mL, (51.30±2.87) pg/mL, and (10.39±0.52) pg/mL] (all P<0.01). Compared with the experimental group, Scr (63.88±2.01) μmol/L, Bun (5.45±0.47) mmol/L, paller score (4.8±0.2), IL-1β (78.61±3.66) pg/mL, IL-6 (297.90±13.64) pg/mL and TNF-α (276.2±20.18) pg/mL were significantly decreased in the levosimendan group (all P<0.01). TUNEL staining showed that levosimendan could improve the apoptosis of renal cells ( P<0.01). The expression of p-ERK protein in the levosimendan group was significantly higher than that in the experimental group ( P<0.01). Conclusions:Lovosimendan could attenuate acute kidney injury following cardiac arrest and cardiopulmonary resuscitation via suppression apoptosis. The mechanism of levosimendan protective effect might be associated with activation of ERK signaling pathway.

ABSTRACT

Objective To explore the protective effects of cannabinoid analogues WIN55212-2 on paraquat poisoned mice. Methods Totally 35 healthy male C57BL/6 mice were randomly(random number) divided into four groups: PQ group (paraquat poisoned, n=10), WIN 1 mg group (PQ+WIN55212-21 mg n=10), WIN 2 mg group (PQ+WIN55212-22 mg, n=10), control group (n=5).The PQ poisoned animal models were established in the PQ group, WIN 1 mg group and WIN 2 mg group by intraperitoneally injection of paraquat with a concentration of 20 mg/kg. Intraperitoneal injection of WIN55212-2 (containing Tween 80 cosolvent) at the concentration of 1 mg/kg and 2 mg/kg was performed 1 h before PQ exposure in the two interfered groups. Equivalent volume of saline was given to the control group. WIN55212-2 was injected twice a week from the second week. In the acute phase (14 d), 5 mice were randomly sacrificed in the PQ group, WIN 1 mg group and WIN 2 mg group, and 3 mice were sacrificed in the control group to obtain blood sample, bronchoalveolar lavage fluid (BALF) and lung tissue. All the remaining mice were executed on day 28, and the tissue samples were collected as mentioned above. HE staining and Masson staining were performed to observe the changes of lung tissues after PQ poisoning. Changes of TNF-α, IL-6 and TGF-β in plasma and BALF were measured by ELISA. Results In the acute phase, the pathological sections of lung tissues in the PQ group, WIN 1 mg group and WIN 2 mg group showed diffuse inflammation, which was improved after the intervention of WIN5522-2, especially in the WIN 1 mg group. IL-6 levels of BALF in the PQ group, WIN 1 mg group, WIN 2 mg group and the control group were (1024.77±124.74)U/L, (620.48±99.76)U/L, (823.29±157.88) U/L, and (180.42±20.22)U/L, respectively. IL-6 levels in the WIN 1 mg group and the WIN 2 mg group were statistically lower than those in the PQ group (P=0.021, P=0.016). However, no difference was found between the two intervention groups(P=0.114). The similar condition was also found in TNF-α in BALF and plasma. In the chronic phase, mice in the PQ group, WIN 1 mg group and WIN 2 mg group showed fibrosis in tissue by HE and Masson staining, and the inflammatory condition was improved after the intervention of WIN5522-2, which was more obvious in the WIN 1 mg group. In BALF, TNF-α level was (321.64±50.54)U/L, (260.23±48.19)U/L, (278.89±29.40)U/L, (89.76 ± 10.87)U/L in the PQ group, WIN 1 mg group, WIN 2 mg group and the control group. Differences were found between the WIN 1 mg group and the control group and the WIN 2 mg group. Similar differences were also observed in plasma TNF-α, but not in TGF-β. Conclusions A small dose of WIN55212-2 can improve the general condition of PQ poisoning mice, and reduce the inflammatory and fibrosis-related cytokines levels in PQ poisoning mice.

ABSTRACT

The theory of "combination of five meridians" focuses on meridians and acupoints as well as compatibility and interrelationship of generation and restriction of five elements. By regulating corresponding meridians to diseased, the relationship of unbalancedis balanced, which can regulate body function and effectively treat diseases. Under the guide of theory "the combination of five meridians", according to etiology and pathogenesis of post-stroke urinary incontinence, wind, fire and phlegm, from three aspects of deficiency, excess and deficient root and excessive surface, under the treatment principle of "nourishing the mother if it is deficient, reducing the son if it is excessive", the original meridian, son meridian, mother meridian, conquering meridian and conquered meridian are selected while the methods of nourishing the mother, reducing the son, reinforcing the suppression and developing the weak are applied, so as to discuss the acupuncture treatment for post-stroke urinary incontinence, which can provide new clinical thoughts of acupuncture treatment for post-stroke urinary incontinence.
