OBJECTIVETo introduce our experience in diagnosis and treatment of 33 patients with Tessier craniofacial clefts.

METHODS33 patients with craniofacial clefts were classified by Tessier classification. According to the type and severity of the clefts, various techniques, from simple local flap transfer to complicated osteotomy and bone grafting were used to correct the deformity in 29 patients.

RESULTSAll patients who underwent corrective operation were satisfied with the result, and there were no complications.

CONCLUSIONS(1) Tessier classification is very important for plastic surgeon to find potential craniofacial deformities related to main signs. (2) No. 7 cleft is one of most common Tessier craniofacial clefts. (3) Each Tessier cleft is unique, therefore, the treatment plans cannot be standardized. Specific corrective operation must be performed on each patient according to the type and severity of the cleft, including simple local flap transfer to complicated osteotomy and bone grafting or distraction osteogenesis.

OBJECTIVETo investigate the role of releasing the fibrous bundles across the levator muscle between the medial canthus and lateral canthsus near the top of tarsus in the correction of the congenital blepharoptosis.

METHODSTwenty-seven patients with 40 eyes of blepharoptosis were undergoing the treatment. It was performed by releasing the fibrous bundles across the levator muscle between the medial canthus and lateral canthsus near the top of tarsus to correct the mild and moderate blepharoptosis. A further procedure can also be added to by folding the levator aponeurosis if necessary. In the severe blepharoptosis, the frontalis aponeurose flap may be applied for the suspension as well during the operation.

RESULTSOf the 40 eyes in 27 cases with mild, moderate and severe blepharoptosis were treated by using this method, with 38 eyes corrected satisfactorily and 2 eyes corrected mostly in the following-ups from 3 months to 1 year.

CONCLUSIONThe above mentioned technique may be a good, simple and effect method to corret congenital blepharoptosis.

Objective To investigate the accuracy and missed diagnosis rate of preoperative ultrasound in the diagnosis of thyroid carcinoma . Methods With the method of natural language recognition ,816 solitary thyroid nodules which received thyroidectomy were enrolled for the analysis of preoperative ultrasound examination and post-operative pathology results . The accuracy and the rate of missed diagnosis of ultrasonography for the diagnosis of thyroid carcinoma and lymph node metastasis were evaluated with the pathological results as the gold standard . Results There were 783 ( 96 .0％ ) malignant thyroid tumors ,6 ( 0 .7％ ) follicular tumor with uncertain malignant potential ,and 27 ( 3 .3％ ) benign thyroid tumors . Ultrasonography yielded an accuracy of 96 .1％ in the differential diagnosis between benign and malignant thyroid nodules and an accuracy of 94 .5％ in the quantification of nodule numbers . 5 .5％ of solitary nodules reported by ultrasound were proved to be 2 or more malignant nodules after the surgery . Regarding the diagnosis of central lymph node ,the preoperative ultrasound yielded an accuracy of 73 .0％and a misdiagnosis rate of 38 .7％ . For the lateral neck lymph node ,the accuracy was 88 .3％ ,and the misdiagnosis rate was 3 .4％ . Conclusions Natural language recognition method can assist clinical research . Ultrasonography is valuable in the diagnosis of thyroid carcinomas and neck lymph nodes . However , ultrasonography has a certain rate of misdiagnosis for the quantification of nodule numbers ,and for the diagnosis of lymph nodes in central and lateral necks .

The odor fingerprint of Pollygonati Rhizoma samples with different mildewing degrees was analyzed and the relationship between the odor variation and the mildewing degree was explored. A fast discriminant model was established according to the response intensity of electronic nose. The α-FOX3000 electronic nose was applied to analyze the odor fingerprint of Pollygonati Rhizoma samples with different mildewing degrees and the radar map was used to analyze the main contributors among the volatile organic compounds. The feature data were processed and analyzed by partial least squares discriminant analysis(PLS-DA), K-nearest neighbor(KNN), sequential minimal optimization(SMO), random forest(RF) and naive Bayes(NB), respectively. According to the radar map of the electronic nose, the response values of three sensors, namely T70/2, T30/1, and P10/2, increased with the mildewing, indicating that the Pollygonati Rhizoma produced alkanes and aromatic compounds after the mildewing. According to PLS-DA model, Pollygonati Rhizoma samples of three mildewing degrees could be well distinguished in three areas. Afterwards, the variable importance analysis of the sensors was carried out and then five sensors that contributed a lot to the classification were screened out: T70/2, T30/1, PA/2, P10/1 and P40/1. The classification accuracy of all the four models(KNN, SMO, RF, and NB) was above 90%, and KNN was most accurate(accuracy: 97.2%). Different volatile organic compounds were produced after the mildewing of Pollygonati Rhizoma, and they could be detected by electronic nose, which laid a foundation for the establishment of a rapid discrimination model for mildewed Pollygonati Rhizoma. This paper shed lights on further research on change pattern and quick detection of volatile organic compounds in moldy Chinese herbal medicines.

Autoimmune diseases (ADs) increase the risk of non-Hodgkin's lymphoma and contribute to poor prognosis of patients. However, the association between immunologic markers and clinical outcome has rarely been investigated. This study aims to analyze the prognostic value of pretreatment immunologic markers in newly diagnosed patients with diffuse large B-cell lymphoma (DLBCL). We retrospectively reviewed the data on 502 patients with DLBCL treated in our institution from January 2013 to March 2018. Survival functions were estimated using Kaplan-Meier method and Cox regression model. The 3-year progression free survival (PFS) and overall survival (OS) rates were 70.2% and 80.9%, respectively, and the complete remission (CR) rate was 78.1%. Among the patients, those with multiple ( ⩾ 3) abnormal immunologic markers had significantly shorter 3-year PFS (52.7% vs. 77.3%, P < 0.001) and OS (68.5% vs. 85.8%, P = 0.001) than those without multiple abnormal immunologic markers. Multivariate analysis revealed that the presence of multiple abnormal immunologic markers and the elevated serum levels of lactate dehydrogenase were the independent adverse prognostic factors for PFS (P = 0.008, P < 0.001) and OS (P = 0.003, P < 0.001). Meanwhile, advanced Ann Arbor stage was an independent adverse prognostic factor for PFS (P = 0.001) and age > 60 years for OS (P = 0.014). In conclusion, the immunologic status was closely related to lymphoma progression, and this study provides new insights into the risk stratification of patients with DLBCL.
