OBJECTIVETo study the effect of growth hormone (GH) combined with Radix Dipsaci on the body growth and the bone mineral content (BMC) of hypophysectomized rats.

METHODSThe GH deficiency rats model was established using the hypophysectomized operation through the skull and the throat. Qualified rats were divided into the sham-operation group (n = 15), the negative control group (n = 13), the GH intervention group (n = 13), and the GH combined with Radix Dipsaci group(n = 12). GH (0.25 mg/kg) was subcutaneously injected from the cervical part in the GH intervention group and the GH combined with Radix Dipsaci group at the same time, while equal volume of normal saline was injected to the rest groups. 0.7 mL/100 kg Radix Dipsaci was given by gastrogavage to the GH combined with Radix Dipsaci group at the same time, while equal volume of normal saline was given by gastrogave to the rest groups. The body weight, the tail length, and the body length were measured during the intervention period. Blood was withdrawn after 14-day intervention. The femoral bone and the tibial bone were taken out. The levels of GH, insulin-like growth factor 1 (IGF-1), alkaline phosphatase (ALP), and osteocalcin (OC) were measured. The width of the tibial epiphyseal plate was measured. The bilateral femur bone mineral density (BMD) and BMC were measured using the dual energy X-ray absorptiometry.

RESULTSThe body weight, the body length, the length of the femoral bone, the length of the tibial bone, the width of the epiphyseal plate, the levels of the GH, IGF-1, ALP, and OC increased in the GH intervention group and the GH combined with Radix Dipsaci group after 2-week intervention, showing statistical difference when compared with the model group (P < 0.01). But there was no statistical difference in the tail length though it also increased (P > 0.05). There was insignificant difference in the aforesaid indices between the two groups (P > 0.05). Compared with the model group, the BMD of the GH combined with Radix Dipsaci group increased with statistical difference (P < 0.01). Compared with the model group, the BMC of the GH intervention group and the GH combined with Radix Dipsaci group increased with statistical difference (P < 0.01). It was highest in the GH combined with Radix Dipsaci group (P < 0.01).

CONCLUSIONSGH combined with Radix Dipsaci showed unobvious effect on promoting the growth. But it could elevate BMD and BMC, and improve the bone metabolism.

BACKGROUND:Insufficient oral soft tissues in the implant zone may have a negative effect on the wound healing and the aesthetic restoration in the late stage. Platelet-rich fibrin can promote the wound healing of soft tissue defects. But there is stil a lack of in-depth studies on the promotion of oral soft tissue defects in animal experiments.
OBJECTIVE: To compare the repairing effects of platelet-rich fibrin and colagen membrane on soft tissue defects of the hard palate in New Zealand rabbits.
METHODS:Fifty-four New Zealand rabbits were randomly divided into three groups (n=14 per group): platelet-rich fibrin group, colagen membrane group and blank control group. A 5 mm-diameter circular ful-thickness soft tissue defect was made in the front of the hard palate, 2 mm distant to the rear maxilary incisors and mucosal edge of the bilateral hard palates. Autologous platelet-rich fibrin membrane or colagen membrane were implanted into the defect in the platelet-rich fibrin group and colagen membrane group, respectively. No treatment was given in the blank control group. General observation of the wound and wound healing analysis were performed at days 3, 7, 14, 21, 28, 56 post operation. Hematoxylin-eosin staining, CD31 immunohistochemical staining and Masson staining were used to observe inflammatory reaction, angiogenesis and colagen formation in the surgical site.
RESULTS AND CONCLUSION:The wound healing rate was fastest in the platelet-rich fibrin group, and no obvious scar formed. At 3 days post operation, there was no difference in the wound healing rates among the three groups; at 7 days, the wound healing rate in the platelet-rich fibrin group was significantly higher than that in the colagen membrane group and blank control group (P < 0.05). At 3 and 7 days after operation, the inflammatory reaction in the platelet-rich fibrin group was less than that in the colagen membrane and blank control groups (P < 0.05); at 14, 21, 28 and 56 days, there was no significant difference between the three groups. At 7, 14, 21 days after operation, the average absorbance value of CD31 in the platelet-rich fibrin group was significantly higher than that in the colagen membrane and blank control groups (P < 0.05). The average absorbance value of colagen formation in the platelet-rich fibrin group was significantly higher than that in the colagen membrane and blank control groups at 7 days after operation (P < 0.05), significantly higher than that in the blank control group at 14 days (P < 0.05), but lower than that in the colagen membrane and blank control groups at 21, 28 and 56 days after operation (P < 0.05). These findings show that platelet-rich fibrin can reduce inflammatory reactions in the process of wound healing, accelerate the angiogenesis, regulate the metabolism of colagen, reduce the formation of scar and improve the quality of wound healing, thereby promoting the repair of oral soft tissue defects.

The present study identified chemical constituents of Honghua Xiaoyao Tablet (HXT) and explored its biological connotation and characteristics on the premenstrual syndrome (PMS) treatment from the "disease-syndrome-symptom" association network. UHPLC-Q Exactive Orbitrap HRMS technology was applied to analyze the chemical constituents in HXT. According to the composition principles, the compatible herbs of HXT were divided into the Shugan Jieyu group, Huoxue Tiaojing group and Yiqi Jianpi group. The candidate targets of the corresponding prescriptions of HXT efficacy groups were collected from the Pharmmapper database and Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine (TCMIP) v2.0. The gene set related to the clinical symptoms included in Traditional Chinese and Western Medicine diagnosis and treatment standards were obtained from SoFDA, GeneCards, DisGeNET, MalaCards and literature published. The "HXT candidate targets-PMS (liver depression, Qi stagnation, and blood stasis syndrome) genes" network was constructed based on the gene interaction information, and further, the core network targets were screened out by topological characteristics of calculating network, and the functional exploration was carried out based on Kyoto Encyclopedia of Genes and Genomes (KEGG) for exploring the therapeutic advantages in PMS treatment of HXT efficacy groups, which were further verified experimentally in vitro. A total of 109 components from HXT were identified, including 20 components from Shugan Jieyu group enriched in the neurological system, estrogen regulation, and "immune-inflammation" related pathways, 77 components from Huoxue Tiaojing group enriched in the blood-circulation system, "immune-inflammation" and estrogen regulation related pathways and 30 components from Yiqi Jianpi group regulating immune inflammation, digestive system, and hormone levels. The biochemical indicator detection demonstrated that both the levels of 5-HT and DA in the hypothalamus tissues and the levels of E₂, NO, VEGF and RLN in the uterine tissues of PMS model rats were lower than those in controls, which the levels of OT, PROG, IL-6, IL-1β and TNF-α in the uterine tissues were increased in PMS group, which were all reversed by the administration of HXT, indicating that this prescription may regulate the synthesis and secretion of estrogen, intervene in neurotransmitter synthesis and signal transduction, reverse the imbalance of "immune-inflammation", and regulate digestive system function through various biological pathways, exerting the liver-smoothing, Qi-regulating, blood-activating and spleen-tonifying comprehensive effects, leading to alleviating the "neuroendocrine-endocrine-immune" system and blood-circulation disorders. The relevant results may provide a reference for clarifying the advantages and efficacy of HXT in treating PMS with liver stagnation, Qi stagnation, and blood stasis syndrome, and exploring its therapeutic advantages. The animal experiment of this study was approved by the Ethics Committee of the Institute of Chinese Materia Medica, China Academy of Chinese Medical Sciences (approval number: 2023B248).
