Objective To investigate the infection of human papilloma virus(HPV) and expression of serum squamous cell antigen (SCCAg) in the follow - up of 120 cervical squamous carcinoma patients who had received operation or operation combined with radiotherapy or only radiotherapy. Methods 120 cases of therapical cervical squamous carcinoma patients were detected HPV - DNA by HC - Ⅱ and serum SCCAg using immunohistochemical method. Results The positive rate of HPV - DNA and serum SCCAg was 49.17% and 17.50% , with a significant difference between them( P 0.05 ). Conclusion HPV - DNA test with HC - Ⅱ for follow - up of cervical squamous carcinoma patients was feasible. It was more sensitive than serum SCCAg. But it suggested that high risk type HPV -DNA test combined with serum SCCAg may be the independent prognostic factors.

Objective To explore the interventional treatment method for complex and refractory lymphatic malformation in children.Methods The clinical data of 78 cases with complex and refractory lymphatic malformation during January 2013 to January 2016 in our department were retrospectively analyzed.The lesions involved the neck in 28 cases,maxillofacial regions in 19 cases,the chest and armpit in 8 cases,the limb in 7 cases,the pelvic cavity and retroperitoneal space in 6 cases,the superior mediastinum in 3 cases,the hypogloeeis in 3 cases and scrotum or perineum region in 4 cases.All the children underwent ultrasound or MRI imaging studies preoperatively.The interventional procedures included:(1) Percutaneous puncture of the LM for sclerotherapy.The lesions were punctured with 20 G needle under the guidance of DSA or ultrasound and the correct positions were confirmed with angiography.The liquid of the lesions was extracted as far as possible.The dosage of sclerosing agents was adjusted according to the size of lesion.The dose of Laurolacrogol injection was 1/10—1/5 of the amount of the liquid in the lesions and the maximum of Laurolacrogol foam was ≤8 ml(20 mg).The dose of Pingyangmycin was ≤ 8 mg.(2) The drainage catheter placement and sclerotherapy.Percutaneous catheter drainage under ultrasound guidance or by surgery was conducted.The liquid in the lesions was drained by retaining the catheter for 1-4 weeks,and sclerotherapy was applied for several sessions during this period.(3) Treatment for one time a week,2 times a session.The interval of every two sessions was 4 weeks.The sclerosing agents included:Laurolacrogol Injection or Pingyangmycin for the lesions with high tension,Laurolacrogol foam for the lesions with low tension,Pingyangmycin for the microcystic lesions.Statistical analysis was conducted using SPSS20.0 software.Results A total of 208 sessions of sclerotherapy for 78 LM patients were performed and average session was (3.0±0.8).Nine patients used Lauromacrogol foam,23 patients used Lauromacrogol Injection,39 patients used pingyangmycin,while combined treatment was conducted in 7 patients.Laurolacrogol injection was used in 20 cases,Pingyangmycin in 29 cases and combination therapy in 5 cases for the high tension lesions in the neck,maxillofacial,chest and armpit.The low tension lesions of pelvic cavity and retroperitoneal space in 6 cases and of superior mediastinum in 3 cases were placed with draining catheters,and treated with sclerotherapy with Laurolacrogol foam.Three cases with hypogloeeis LM was neonates,who were treated with Laurolacrogol injection.The lesions on the limb and scrotum or perineum region were almost microcystic,were treated with Pingyangmycin in 9 cases and with combination therapy in 2 cases.The total curative rate was 97.4％ (76/78),total effective rate was 100％ (78/78).Imaging examinations showed that the cavities were closed or only a small amount of residual sclerotic lesions were present.Clinical examinations showed that the surface masses almost disappeared.The follow up period was 6 months to 2 years.There were no serious complication and adverse reactions occurred.Conclusions Interventional treatment is a safe,effective,and minimally invasive treatment for the complex and refractory lymphatic malformation.In order to receive the best treatment effect,we should use targeted therapy for different region and type of LM.

BACKGROUND:Rena gel and expansive sponge are two kinds of nasal packing materials, but there is stil a lack of comprehensive analysis on their filing effects.
OBJECTIVE:To compare the therapeutic efficacy of Rena gel and expansive sponge on nasal hemorrhage and postoperative nasal packing as wel as adverse reactions.
METHODS: A computer-based search of CBM, PubMed, EMBASE, Cochrane Library was performed for articles addressing randomized controled trials of Rena gel and expansive sponge as filing materials. The keywords were “Rena gel, randomized controled, expansive sponge” in Chinese and English, respectively. Then, aching feeling during filing and removal, sweling pain, bleeding, and bleeding control were compared and analyzed through a Meta-analysis.
RESULTS AND CONCLUSION:There were four randomized controled trials, involving 115 patients. The severity of pain was higher in the expansive sponge group than the Rena gel group when the filing materials were placed or removed (P < 0.05). However, there was no difference in the severity of pain between the two groups at 6 hours of filing (P > 0.05). The severity of sweling pain was higher in the expansive sponge group than the Rena gel group at 1 and 6 hours after filing (P < 0.05). When the filing materials were removed, the expansive group showed more severe bleeding than the Rena gel group (P < 0.05). No differences in the bleeding when filing and bleeding control were found between the two groups (P> 0.05). In addition, it was more difficult to fil or remove the expansive sponge from the nasal cavity (P < 0.05). These findings indicate that the Rena gel is superior to the expansive sponge in terms of pain, sweling pain, and bleeding when filing or removing the materials. But there is no difference in bleeding control between the two kinds of filing materials.

To explore the clinical characteristics and imaging features of miliary tuberculomas in central nervous system (CNS).A total of 5 cases diagnosed with tuberculosis in CNS first diagnosed by neurologists in Navy General Hospital of PLA were enrolled in the study.All clinical and imaging data were collected and analyzed retrospectively.The main initial symptoms were fever and headache (4/5).Multiple diffused miliary lesions were shown by brain MRI,with maximum diameter ranged from 1-4 mm and ringshape or nodular enhancement after gadolinium injection.As mycobacterium tuberculosis could seldomly be found in serum and cerebrospinal fluid,contrast MRI remains the effective method for detecting miliary tuberculomas in CNS.

NAC transcription factors involved in plant growth and development, as well as responses to biotic and abiotic stress. RNAi Vectors for SmNAC transcription factors of Salvia miltiorrhiza was constructed by using Gateway cloning technology, in order to further study the function of SmNAC1 transcription factor. According to Gateway cloning technology, the specific fragments of SmNAC1 containing attB adapter was amplified by PCR using ultra-fideling phusion polymerase of NEB. By the BP recombination reaction, the PCR product containing attB was transferred to an donor vector (pENTR/SD/D-TOPO). Finally, SmNACi specific gene was cloned into pK7GWIWG2D plant expression vectors by LR recombination reaction. Experimental results showed that Gateway cloning technology provide a rapid and highly efficient way to clone the interested gene.

To obtain the key genes for chlorogenic acid biosynthesis of Lonicera hypoglauca, four new genes ware obtained from the our dataset of L. hypoglauca. And we also predicted the structure and function of LHPAL4, LHHCT1 , LHHCT2 and LHHCT3 proteins. The phylogenetic tree showed that LHPAL4 was closely related with LHPAL1, LHHCT1 was closely related with LHHCT3, LHHCT2 clustered into a single group. By Real-time PCR to detect the gene expressed level in different organs of L. hypoglauca, we found that the transcripted level of LHPAL4, LHHCT1 and LHHCT3 was the highest in defeat flowers, and the transcripted level of LHHCT2 was the highest in leaves. These result provided a basis to further analysis the mechanism of active ingredients in different organs, as well as the element for in vitro biosynthesis of active ingredients.
