OBJECTIVE: To explore the therapeutic effects of Ziyin Xiehuo Recipe (ZYXHR) for nourishing yin and lowering fire and Yishen Tianjing Recipe (YSTJR) for nourishing kidney and replenishing essence on regulating the gonadotrophic and somatotrophic functions of hypothalamic-pituitary axis, and to reveal the mechanisms of ZYXHR and YSTJR in modulating the course of pubertal development of children with precocious puberty. METHODS: The pubertal rats were fed with ZYXHR or YSTJR for 30 days, and the parameters of rats were monitored as the followings: The content of gonadotropin-releasing hormone (GnRH), the frequency and amplitude of GnRH impulse releasing, the releasing amounts of aminoacid neurotransmitters, and neuropeptide Y (NPY) and beta-endorphin (beta-END) in the gonadotrophic area of the hypothalamus were detected with neurobiological methods (push-pull perfusion, homogenate, incubation of brain slices, and immunohistochemical staining). The levels of gene and protein expressions of GnRH, growth hormone releasing hormone (GHRH) and somatostatin (SS) in hypothalamus, and follicular stimulating hormone (FSH), luteinizing hormone (LH) and growth hormone (GH) in adenohypophysis as well as insulin-like growth factor I (IGF-I) in metaphysis were determined with real time reverse transcription-polymerase chain reaction (RT-PCR). RESULTS: The ZYXHR could reduce the activity of GnRH neurons in hypothalamus through inhibiting the release of central exciting aminoacid neurotransmitters, whereas promoting the release of central inhibiting aminoacid neurotransmitters, NPY and beta-END in gonadotrophic area of hypothalamus. The expression levels of GnRH, FSH and LH mRNAs were down-regulated while the expression level of SS mRNA in hypothalamus was up-regulated in the ZYXHR-treated group. The GH mRNA in hypophysis and the IGF-I mRNA in metaphysis were both down-regulated by ZYXHR. The YSTJR could promote the activity of GnRH neurons in hypothalamus through inhibiting the release of NPY in gonadotrophic area of hypothalamus, up-regulating the expression levels of GnRH, FSH, LH and GH mRNAs in hypophysis, and IGF-I mRNA in metaphysis, while down-regulating the expression level of SS mRNA in hypothalamus. CONCLUSION: The ZYXHR and YSTJR could both regulate the gonadotrophic and somatotrophic functions of hypothalamic-pituitary axis through modulating the neuroendocrine regulation and the gene expressions of GnRH and SS in hypothalamus, GH, FSH and LH in hypophysis, and IGF-I in metaphysis. These may be the chief mechanisms of ZYXHR and YSTJR in modulating the course of pubertal development and ameliorating the skeletal development in children with precocious puberty.

Objective To observe the effects of electroacupunture (EA) on the abnormal hypothalamus-pituitary-adrenal (HPA) axis and the expression of hypothalamic corticotropin-releasing factor (CRF) peptides family and CRF receptor (R)1 mRNA in traumatized rats,so as to study its underlying mechanism in improving traumatic injury. Methods Forty male Sprague-Dawley rats were randomly divided into normal control group (n=10),normal+ EA group (n=10),surgical trauma (model) group (n=10),and model+EA group (n=10). Traumatic injury model was established by performing an exploratory laparotomy in the rats under anesthesia. EA (2 Hz/15 Hz,1-2 mA) was administered for 30 min via two stainless steel needles inserted in "Zusanli" (ST 36) and "Sanyinjiao" (SP 6). Serum adrenocorticotropic hormone (ACTH) ,corticosterone (Cort),luteinizing hormone (LH) and testosterone (T) contents were detected by double-antibody radioimmnoassay. Hypothalamic CRF and CRF R1 mRNA expression was assayed by reversed transcription polymerase chain reaction (RT-PCR) technique. Results The serum ACTH concentration decreased significantly in model group (P0.05). The serum Cort level increased significantly in model group(P0.05). The expression of hypothalamic CRF mRNA decreased significantly in model group (P0.05). Conclusion EA of "Zusanli" (ST 36) and "Sanyinjiao" (SP 6) can improve surgical trauma-induced HPA disorders,which is probably related to its effects in upregulating CRF mRNA expression and downregulating Ucn 1 mRNA expression in the hypothalamus.

Objective To investigate the anatomical classification of left intrahepatic bile duct (LHD) and the pattern of bile duct reconstruction during pediatric split liver transplantation and their relationship with postoperative biliary complications. Methods Clinical data of 75 pediatric recipients undergoing split liver transplantation were analyzed retrospectively. Before splitting the donor liver, iopromide injection was used for retrograde cholangiography through the common bile duct. According to the patterns of intrahepatic bile ducts in the second, third and fourth segments, the anatomical classification of LHD of the donor liver was determined. The biliary reconstruction regimens for different classification types of LHD were summarized. The incidence and treatment of biliary complications after pediatric split liver transplantation were analyzed. Results Among 75 donor livers, the anatomical classification of LHD included 57 cases (76%) of type Ⅰ, 9 cases (12%) of type Ⅱ, 4 cases (5%) of type Ⅲ and 5 cases (7%) of type Ⅳ LHD, respectively. Among 75 pediatric recipients, 69 cases (53 cases of type Ⅰ, 8 type Ⅱ, 4 type Ⅲ and 4 type Ⅳ) underwent the left hepatic duct-jejunum Roux-en-Y anastomosis, 1 case received common bile duct-jejunum Roux-en-Y anastomosis (type Ⅳ), and 5 cases underwent the left hepatic duct-common bile duct end-to-end anastomosis (4 cases of type Ⅰ and 1 type Ⅱ). Postoperative biliary complications occurred in 6 cases (8%), including 3 cases of biliary anastomotic stenosis, 2 cases of biliary anastomotic leakage and 1 case of bile leakage on the hepatic resection surface. Among 6 recipients, 4 cases were classified as type Ⅰ and 2 cases of type Ⅲ LHD. No significant difference was observed in the incidence of biliary complications between typical type and anatomical variant type of LHD (all P > 0.05). Among 3 recipients with biliary anastomotic stenosis, 2 cases underwent percutaneous transhepatic cholangial and drainage (PTCD) and 1 case repeatedly received biliary-intestinal anastomosis. Two cases of biliary anastomotic leakage underwent PTCD and 1 case of bile leakage on the hepatic resection surface received local drainage. All 6 children survived after treatment. Conclusions Anatomical variation of LHD can be observed in 24% of donor livers, and type Ⅱ accounts for the highest proportion of 12%. Prior to donor liver splitting, routine cholangiography and fine biliary anastomosis may effectively lower the incidence of biliary complications. The incidence of postoperative biliary complications is not significantly associated with the anatomical classification of LHD.
