Neonatal visceral injury have high clinical incidence and it is hard to make clinical diagnosis early by routine inspection. In recent years,researches have shown that neonatal multiple organs damage can be diagnosed early by analyzing some special components in urine. Besides,urine analysis is a noninvasive examina-tion method and it is suitable for clinical promotion. This paper enumerates the application of neonatal urine ex-amination in the early diagnosis of kidney damage,bronchial pulmonary displasia,patent ductus arteriosus,hy-poxic ischemic encephalopathy and metabolic disease.

Objective To observe the effect of Naoling decoction on hippocamal histomorphology and the expression of amyloid precursor protein (APP) in CA3 region in rats with Alzheimer's disease (AD), and to explore the therapeutical and the potential mechanism. Methods Forty SD rats were classified into 5 groups: a normal group, a sham-operated group, an AD group, a Naoling decoction group, and a Naofukang group. Alzheimer's disease model was established by Aβ1-42 injected into the hippocamal in the rats. The faculty of learning and memory was evaluated by Morris water maze. The changes of cell morphology were detected by HE staining. Expression of APP in CA3 region was mea-sured with immunohistochemical staining. Results Morris water maze experiment showed that the escape latency of hidden platform in the AD group were delayed significantly (P＜0.05) and the average times of passing was decreased (P＜0.05). In the hippocampal CA3 field of the AD rats, HE staining and immunohistochemical test showed that pyramidal cells disturbed, neurons decreased significantly and expression of APP protein increased (P＜0.05). Naoling decoction treatment improved pyramidal cellular disorders and decreased APP expression. Conclusion Naoling decoction can distinctly improve the learning and memory ability, and reduce the expression of APP in the AD model rats, suggesting that Naoling decoction can be used for the treatment of AD in rats.

Objective To observe the effect of Naoling decoction on the expression of iNOS in hippocamal CA3 region in rats with Alzheimer's disease (AD), and to explore the potential mechanism. Methods Forty SD rats were classified into 5 groups: a normal group, a sham operated group, an AD group, a Naoling decoction group, and a Naofukang group. The Alzheimer's disease model was established by injecting Aβ1-42 into the hippocamal in the rats. Expression of iNOS in the CA3 region was measured with immunohistochemical staining. Results Compared with the normal group, the expression of iNOS protein in the hippocampal CA3 fields in the AD group increased (P<0.05). Naoling decoction decreased the iNOS expression. Conclusion Naoling decoction can significantly reduce the expression of iNOS in the AD model rats, suggesting that Naoling decoction can be used for AD rats.

30nm) accounted for 3.5% of these contacts. The mean maximum diameter of the vesicles was 49.4 nm, the volume density was 0.023 and profile density was 36. The distribution of the vesicles was as following: 29.1% opened onto or touched the abluminal membrane, 44,9% without visible connection to either surfaces, 26% opened onto or touched the luminal membrane. It was concluded that the mechanism of lymph formation in the stomach seems to be different from that of those organs such as heart, liver, kidney and thyroid. The present study suggested that the intercellular pathway may act as the primary route for lymph formation and macromolecule transportation, and the intracytoplasmic vesicular system may also play certain role in the transport of macromolecules.

The three-dimensional organization and anastomoses of lymphatics in the rabbit stomach were demonstrated by scanning electron microscopy of lymphatic corrosion casts. Casting medium is the diluted low viscosity Mercox used for intraparenchymatous injection into the mucosal, submucosal, muscular and serous layers of the stomach. The lymphatic capillaries with blind ends were found in the deep mucosa and the lymphatic capillary networks and lymphatic plexus were observed in all the submucosal, muscular and serous layers. The distinct imprints which correspond to the bicuspid valves of lymphatics and the oval or fusiform impressions of the endothelial nuclei were seen on the casts.

Objective To investigate the shaping rules of the femoral heads in the morphological perspective.The research objects are hips of normal children and children who have developmental dysplasia of the hip(DDH) and after closed reduction or limited open reduction.At the same time measuring and analyzing normal hip femoral head form changing with the children's age.Methods Collecting the DDH cases that after closed reduction and limited open reduction from June 2013 to December 2015.The follow-up period was more than 1 year.MRI images were collected before surgery,6 months after surgery,1 year after surgery,and 2 years after surgery.In addition,normal hip joint MRI images from 0 to 18 years old were collected for controlled study.Descriptive data on the affected side,healthy side and normal hip joint morphology of the hip dislocation were statistically analyzed.Results (1) The mean eccentricity of femoral head in normal hip decreased from (0.362 ±0.069) at 1-2 years to(0.141 ±0.028) at 18-19 years.(2) The eccentricity of femoral head before closed reduction and limited open reduction were both greater than those of healthy side.There was no significant difference in the eccentricity of the femoral head between the healthy side and the affected side at 1 year after closed reduction (P =0.211).There was no significant difference in the diameter of the bilateral femoral heads (P =0.871).The eccentricity of the bilateral femoral heads remained different at 2 years after limited open reduction (P =0.028),and the diameter of the affected femoral head exceeded the healthy side 1 year after surgery (P =0.001).Conclusion The shape of the femoral head of normal children gradually approaches the spherical shape with age.One year after closed reduction of DDH,the shape and size of the affected femoral head are close to the healthy side,and the femoral head of the affected side increases more than the healthy side in 1 ～ 2 years after open reduction and the morphology is still different.

In October 2022, the European Society for the Study of the Liver (EASL) publishes officially the EASL Clinical Practice Guidelines on the management of cystic liver diseases, which covers the diagnosis, treatment, and management of hepatic cysts, mucinous cystic neoplasms of the liver, biliary hamartomas, polycystic liver disease, Caroli disease, Caroli syndrome and peribiliary cysts. Combined with the contrast-enhanced imaging examination, the guideline is of great significance for standardized diagnosis and treatment of hepatic cystic lesions. The authors interpret the guideline in detail, and systematically introduce the key points of assessment of various types of cystic liver disease and related recommendations for treatment. Meanwhile, the future applications and research directions are further prospected in order to provide more evidence basis for the clinical manage-ment and decision-making for patients with cystic liver diseases.

In the twentieth session of the National Clinical Oncology Conference and 2017 annual meeting of Chinese Society of Clinical Oncology (CSCO),many progressions have been made in the diagnosis and treatment of primary liver cancer.(1) A preliminary report of the real world study of primary liver cancer in China was released.(2) Emerging diagnostic techniques and predictive models can detect preoperative liver cirrhosis and risk of postoperative liver failure in patients with hepatocellular carcinoma (HCC).(3) Photodynamic diagnostic technology can ensure histological clearance with negative surgical margin and preserve as much liver parenchyma as possible.(4) Lenvatinib is expected to be the first-line targeted drug for the treatment of patients with unresectable HCC following sorafenib.(5) Immunotherapy with Nivolumab and Pembrolizumab is still a hot topic in the field of HCC management.(6) Though a vast heterogeneity of patterns of liver resection for HCC exists between two large centers from the East and the West,their surgical safety and long-term efficacy are actually comparable.(7) Routine lymphadenectomy,active surgical intervention for patients with late-stage tumors,ensuring the negative margins of resection and comprehensive treatment of postoperative recurrence are expected to improve the long-term outcomes of intrahepatic cholangiocarcinoma (ICC).

OBJECTIVE: To observe the effect of Naoling decoction on the learning and memory behaviors and the expression of microglia and IL-6 in hippocampal CA3 region of rats with Alzheimer's disease (AD), and to elucidate the potential mechanism. METHODS: Thirty SD rats were randomly divided into 5 groups: a normal group, a sham-operation group, an AD group, a Naoling decoction group and a Naofukang group. The spatial learning and memory behaviors of the rats were investigated by water maze and Y-maze. The Alzheimer's disease model was established by injecting Aβ1-42 into the hippocamal of the rats. Expression of OX-42 (one of the microglia specific markers) and IL-6 in the CA3 region of hippocamal was measured by immunohistochemical stain. RESULTS: Morris water maze experiment showed that the escape latency of hidden platform in the AD group was significantly delayed (P<0.05) and the average times of passing was decreased (P<0.05). Y-maze test showed that the times needed to the learn how to evade the electrical stimulation in the AD group was most than in other groups (P<0.05). Compared with the AD group, the Morris water maze test and Y-maze test of the Naoling decoction group were significantly different (P<0.05). The expression of OX-42 and IL-6 in the CA3 region of hippocamal in the Naoling decoction group was decreased (P<0.05). CONCLUSION Naoling decoction can improve learning and memory, and weaken the expression of OX-42 and IL-6 in hippocampal CA3 of AD rats, which may partly be the therapeutic mechanism of Naoling decoction for AD.
