AIM: To study the effects of different process methods on the content of total flavonoids and the aqueous extract from Rhizoma Drynariae. METHODS: The contents of total flavonoids of Rhizoma Drynariae processed in different ways were assayed by polyamide chromatography and ultraviolet spectroplotometry; the contents of the aqueous extract were assayed by extraction in water. RESULTS: The contents of total flavonoids and the aqueous extract in Rhizoma Drynariae increased after it was processed and purified. The contents of total flavonoids and the aqueous extract in Rhizoma Dyrnariae hotted in sands, at constant temperature oven and microwave process were not influenced, but easier to be extracted in water by these methods. CONCLUSION:Microwave processis better than the other methods.

Objective To evaluate endoscopic ultrasonography (EUS) for TN restaging and predicting response to advanced gastric cancer after neoadjuvant chemotherapy. Methods A total of 22 patients,15 males and 7 females, mean age 64 (36-80 years ), with advanced gastric cancer were recruited to the study from June 2007 to December 2009 with written informed consents. All patients underwent 3 cycles of neoadjuvant chemotherapy ( Folfox 6 ), and subsequent surgery ( R0 resction) in 3-4 weeks after chemotherapy. EUS was performed 1-2 weeks before and 1-2 weeks after chemotherapy. EUS TN staging was compared with pathological findings. The correlation of peri-chemotherapy EUS TN staging with postoperative pathological response was evaluated. Results After chemotherapy, the overall accuracy of EUS T staging was 63.6% (14/22), with overstaging (36. 4%, 8/22) more frequent than understaging (0). The overall accuracy of N staging was 54. 5% (12/22) with 4 ( 18. 2%, 4/22) overstaging and 6 ( 27. 3%, 6/22 ) understaging. EUS revealed T and/or N downstaging ( concyrrence of T and N downstaging was accounted once) after chemotherapy in 10 patients, with 9 T downstaging (4 from T3 to T2, 5 from T4 to T3) and 4 N downstaging (4 from N1 to N0). TN downstaging was correlated with pathological response, with 7 patients achieving pathological response 2 and 1 patient 3. Conclusion T and N restaging by EUS after neoadjuvant chemotherapy in patients with locally advanced gastric cancer is not accurate enough. However, T and/or N downstaging confirmed by EUS is well correlated with a better degree of pathological response to chemotherapy.

This study was aimed to optimize the extraction process of double-marker components for Arctium lappa L. The central composite design and response surface methodology was used. According to 3 main factors, the extraction rates of arctiin and arctigenin was used as evaluation indexes. Multiple linear regression and two-order polynomial equation were used. The binomial fitting model was performed in the optimization of arctiin and arctigenin extraction technology. The results showed that the indentified optimized extraction technology of arctiin and arctigenin was 70% ethanol, 24-fold, ultrasonic solvent extraction for 15 minutes. It was concluded that this technology was able to extract large amount of arctiin and arctigenin, which provided experiment evidences for arctiin and arctigenin preparation. It also provided references for the development and utilization of arctiin and arctigenin.

Objective: To study common problems in BRAF gene mutation detection, and conditions for repetition testing using thyroid fine needle aspiration specimens. Methods: A total of 8 644 cases of thyroid fine-needle aspiration specimens at China-Japan Friendship Hospital were collected between February, 2012 and July, 2018. BRAF gene mutation was detected by real-time PCR. Repeat testing was performed in 237 cases when the results were inconsistent with clinical or cytological diagnosis or when uncertain results were obtained. Results: The final positive rates of BRAF mutation was 22.0% (1 897/8 625). Nineteen cases were excluded due to inadequate DNA samples. The average Ct value of internal quality control was 16.061, and the average Ct value of the positive samples was 19.147. Among 237 repeat tests, 51.4% (19/37) continued to have poor DNA quality and 48.6% (18/37) had adequate DNA resulting in 1 positive case and 17 negative cases. In 40 repetition of initial negative cases, results were unchanged. In initial positive cases, 40.4% (40/99) with a difference of Ct value (between BRAF gene and internal quality control) between 8 to 12 turned negative after repetition, 69.8% (37/53) of these cases with a difference of more than 12 turned negative after repetition. The sensitivity and specificity of BRAF mutation were 83.97% and 96.94%, respectively. Conclusions Difference between BRAF gene Ct value and internal quality control Ct value is recommended as a reliability index for the test result. Cases with a difference greater than 8 should be subjected to repeat testing.

Objective To investigate the diagnostic value of prenatal ultrasonography in the fetal hemivertebra. Methods The ultrasonographic findings of three fetuses with hemivertebra diagnosed in our hospital were reviewed and compared with those of postnatal ultrasonography,other image modalities,and autopsy. Results In all fetuses,a distortion of the spine was observed where only one half of the vertebra could be identified. The parents opted for termination of the pregnancy in one case and the deformity was confirmed by autopsy. The other two fetuses were delivered and in one fetus the diagnosis was confirmed by radiological assessment. Conclusions Hemivertebra can be diagnosed accurately by second-trimester ultrasonography. The prognosis is mostly favorable when no other anomalies are associated. Meticulous examination may disclose the lesion and help decide the fate of pregnancy.

Objective To determine the diagnostic value of two and three dimensional ultrasound in detecting fetal hand malformations. Methods In the retrospectively analysis,the severe fetal hand malformations detected by prenatal ultrasound during the recent three years in our hospital were classified according to the prenatal sonographic characteristics,family history,karyotype analysis and autopsy results,etc.Results Fourteen fetuses with hand-anomaly were detected during the 16-28th week of gestation,both hands were affected in 10 cases,with the same morphology bilaterally in 8 cases.Thirteen cases had other abnormal sonographic findings.They were detected and classified into three categories,Wrist deformity (9 cases),three fetuses were associated with total absence of radius and radial clubhand,and six fetuses had palmar deviated hands,with various etiologies including familial hereditary arthrogryposis multiplex congenita,distal type 1 (AMCD1),amniotic band syndrome,body stalk anomaly,trisomy18 and micromelia.Hand (figer) hypoplasia or aphasia (3 cases),one hand was absent in one fetus without associated anomaly,absence of five fingers with ipsilateral multicystic dysplastic kidney in the second fetus,and the third fetus had split hand/foot malformation (SHFM).Overlapping fingers (4 cases),three of them were trisomy18,and two fetuses had both wrist deformity and overlapping fingers.Conclusions Prenatal two and three dimensional ultrasound play an important role in detecting and diagnosing severe type of fetal hand malformations.

OBJECTIVETo study the clinical and pathologic features of primary cardiac inflammatory myofibroblastic tumor.

METHODSA total of 4 patients with primary cardiac inflammatory myofibroblastic tumor were encountered during the period from 1993 to 2013 in National Center for Cardiovascular Disease. The clinical features, imaging findings and outcomes of the 4 patients were evaluated. ALK protein expression and ALK gene status were studied using the archival tumor tissues.

RESULTSThere were 1 female and 3 male patients. The age of patients ranged from 5 months to 30 years (mean = 16 years). The tumor was located in right ventricle (n = 2), right atrium (n = 1) or pericardium (n = 1). Histologic patterns included 2 cases of fibrous histiocytoma type, 1 case of granulomatous type and 1 case of sclerosing type. Immunohistochemical study showed that 2 cases expressed ALK protein. Fluorescence in-situ hybridization however did not reveal any ALK gene rearrangement.

CONCLUSIONSInflammatory myofibroblastic tumor of the heart is rarely encountered and easily misdiagnosed. It carries distinctive clinical and pathologic features. ALK protein expression is helpful in arriving at the correct diagnosis.
