Splenogastric hygropyrexia syndrome, a common syndome in clinical practice, responds well to the therapy of traditional Chinese medicine (TCM). In view of the complexity of TCM syndrome formation, proceeding from different aspects such as Helicobacter pylori (Hp) infection, expression of inflammatory factors, mucosal protection and change in micro-ecosystem, the authors proposed that Hp infection in gastric mucosa, nuclear factor-kappa B activation, over-expression of heat shock protein 70, and "excessive evil, dyssplenism and confliction between healthy energy and evils" due to disequilibrium between Hp and lactobacillus acidophilus in gastric mucosa and coated tongue may be the important links in the formation of Hp related gastrosis with splenogastric hygropyrexia syndrome.

OBJECTIVE:Bone morphogenetic protein (BMP) plays a vital role in the prevention and treatment of skeleton diseases, recently researches on the molecular mechanism of sheep prolific FecB gene indicated that BMP and its receptors have important influence on animal follicular development. In this study the influence of different type BMPs andits receptors on the follicular development was reviewed in order to explore effective modulation on animal reproduction.DATA SOURCES: Computer was applied to retrieve Medline database on the related literatures from January 1998 to June 2005. The retrieval words were "BMP" and "BMPR" that combined respectively. Language in the articles was limited to English. Simultaneously related articles were also computer searched in China periodical full text database and Wanfang databases from January 1996 to December 2005 with the retrieval words of "BMP, BMPR", that limiting the article language to Chinese.STUDY SELECTION: At first, the document was retrieved, altogether 200 studies on BMP and its receptors were enrolled including 140 Chinese literatures and 60 English literatures.DATA EXTRACTION: these literatures were screened and 30 were included for relating to the BMP characteristic, as well as the influence of BMP and its receptors on follicular development and reproductive endocrine.DATA SYNTHESIS: Of the 30 literatures, 18 experiments discussed the function of BMP and its receptors and its signal transduction mechanism,12 were about the influence of different BMP on reproductive cell secretion, as well as receptor mutation on ovulation.CONCLUSION: BMPs family plays vital role in animal reproductive modulation, current experiments prove that the changes of signal transduction due to BMP receptor gene mutation has made breakthrough for the exploration of the prolific mechanism in sheep. Moreover studies on follicular development modulation and ovulation mechanism are liable to provide theoretical reference for the prolific modulation in sheep or other species.

Objective:
To describe the clinicopathologic features, diagnosis and differential diagnosis of ovarian carcinoid tumors.
Methods:
A retrospective chart review was performed of all patients diagnosed with primary ovarian carcinoid tumors at Fudan University Shanghai Cancer Centre from 2007 to 2017.
Results:
The histologic analysis of these carcinoid tumors revealed 3 were insular, 1 was trabecular, 1 was mucinous, and 10 were strumal. Histologic features of insular and trabecular carcinoid were similar to other parts of the neuroendocrine tumor. Strumal carcinoid was composed of thyroid tissue intimately admixed with carcinoid tumor, showing trabecular pattern. Mucinous carcinoid was resembles Krukenberg tumor. Most ovarian carcinoid tomours were diffusely positive with at least one neuroendocrine marker, especially synaptophysin (14/14) and CD56(9/10). The median follow-up time was 53 months, 1 patient with squamous-cell carcinoma of cervixrecur rence in vaginal after 37 months, and only 1 patient died of disease. The remaining patients were disease-free survival.
Conclusions
Primary carcinoid of the ovary is a very rare low grade malignant monodermal teratomas and somatic-type tumours arising from a dermoid. The diagnosis and differential diagnosis mainly relies on the histopathologic characteristics and the immuno-phenotype. Primary ovarian carcinoid almost always exhibit a benign clinical behavious except mucinous carcinoid.

Objective:To explore the evolution of imaging findings on dynamic chest high resolution CT(HRCT) in patients with mild COVID-19.Methods:The data of epidemiology, clinical data and continuous dynamic chest high-resolution CT images of the patients with mild COVID-19 were analyzed retrospectively. Twenty-five patients (including 24 common type and 1 mild) were enrolled in the group, including 14 males and 11 females, with age of (42±12) years and hospital stay of (19±5) days. The basic images and dynamic images of HRCT were analyzed and compared by the radiologists.Results:The clinical manifestations were fever (22 cases), cough (18 cases), expectoration (8 cases), pharyngeal pain (6 cases). Most laboratory tests lacked specificity. There were no significant abnormalities on chest CT of one mild patient. HRCT findings of the common type were as follows: (1) the distribution of the lesions: most of the multiple lesions involved both lungs (19 cases), with average of 3 (3±1) lobes, located in the peripheral pulmonary zone near the pleura (22 cases); (2) the morphology and density of the lesions: most of the lesions were ground glass density foci (22 cases), which were patchy and massive (18 cases), nodular (10 cases) and arc broadband (7 cases); with the development of the disease, the density of some lesions increased with localized pulmonary consolidation (10 cases), accompanied by air bronchus sign (5 cases) and halo sign (5 cases). Dynamic changes of HRCT images in the chest: the positive manifestations were found on the 5th (5, 6) day after the onset of the disease, the progressive time of CT lesions was 5 (5, 7) days, the peak time of CT lesions was 11 (10, 13) days, and the turning time of CT lesions was 9 (8, 11) days.Conclusions:Dynamic chest HRCT can monitor the basic evolution process of the disease in patients with mild COVID-19, and provide a more intuitive basis for clinical early diagnosis and treatment.
