BACKGROUND:The rate of tuberculosis infection was high in patients after renal transplantation. Clinical manifestation is not typical, which brings inconvenience to diagnose.
OBJECTIVE:To summarize the diagnosis and therapeutic methods of tuberculosis infection after al ograft renal transplantation.
METHODS:Relevant diagnosis and therapeutic method of 13 patients with tuberculosis infection after renal transplantation were retrospectively analyzed in the Department of Organ Transplantation, Zhujiang Hospital of Southern Medical University from January 2010 to October 2013.
RESULTS AND CONCLUSION:The onset time was 4-120 months after operation;62%(8/13) patients within 18 months after transplantation. Patients affected long-period fever, mainly low-grade fever. Four cases were identified according to the history, imaging data in combination with positive pathogenic diagnosis. Five cases were identified according to the history, imaging data combined with lung biopsy histopathology. The remaining four cases were identified according to the history, imaging data with experimental effective anti tuberculosis treatment. Early pulmonary symptom was not obvious. Chest CT was helpful in early diagnosis and differential diagnosis. Al patients fol owed early, law, ful , right amount, combined with principles of anti-tuberculosis treatment, and treatment usual y lasted for 6-10 months. They were given combined anti-tuberculosis infection drugs, adjustment of immunosuppressive agents and five-ester capsule for liver protection therapy. Thirteen patients were alive, no deaths. Two cases with early infection without timely treatment suffered from acute rejection, leading to loss of graft function and returned to hemodialysis. The others were cured and left hospital. Renal function was normal after 6-month fol ow-up (serum creatinine). Results indicated that after renal transplantation, patients with pulmonary tuberculosis should be early detected, early diagnosed and early treated. CT guided biopsy can be used as an effective and feasible means for diagnosis and identification of smear negative pulmonary tuberculosis after renal transplantation. Adjustment of immune scheme, anti-tuberculosis treatment and five-ester capsule significantly reduced calcineurin inhibitor dose, and lessened their adverse reactions.

OBJECTIVETo compare the thin anterolateral flap with forearm flap in tongue defect repairing, and to introduce our methods and experiences in the tongue reconstruction with the thin anterolateral flap.
METHODSThe clinicopathologic data of 46 cases with tongue carcinoma were obtained from School of Stomatology, Nanjing University Medical Center, Nanjing University from December 2009 to December 2011. To compare two methods of incidence of vascular crisis, tongue shape, language and swallowing functional recovery.
RESULTS46 patients with tongue carcinoma were performed the tongue reconstruction in 12 month, which 12 cases were used the thin anterolateral flap and 34 cases were used the forearm flap. In the thin anterolateral flap group, All cases were succeeded. 1 case occurs vascular crisis. In the forearm flap group, 33 cases were succeeded, and 1 case occurs necrosis. 3 cases occurs vascular crisis. The results of comparing two methods showed that: no obvious differences in the tongue shape, and no obvious differences in the function of language and swallowing.
CONCLUSIONSThere no obvious differences in the reconstruction of tongue defect between the thin anterolateral flap and the forearm flap. The thin anterolateral flap have some advantages: little influence is on the donor site, the flap extent is abundant, the donor site is not spectacular. The thin anterolateral flap should be piror method for the tongue defect repairing.

OBJECTIVE To investigate the effect and its mechanism of laminaria japonica polysaccharides(LJP) on human laryngeal carcinoma cell Tu212 growth. METHODS The laryngeal squamous cell Tu212 in logarithmic growth phase were treated by laminaria japonica polysaccharides(80, 160, 320 μg/ml) and cisplatin(1.8 mg/L). The MTT assay was used to evaluate cell growth inhibition rate after 24h, 48h and 72h. The flow cytometry with PI staining were used to estimate cell cycle distribution after 48h. The fluorescent microscopy was used to estimate cell apoptosis after 48h. The western blot was used to evaluate the expressions of Cyclin B1 and Bcl-2. RESULTS The cell proliferation was inhibited by cellular LJP in a dose and time dependent manner. Tu212 cells proliferation were stopped at the G2/M phase treated with LJP after 48h. Cell apoptosis was observed clearly by f luorescent microscope after 48h. The expressions of Cyclin B1 and Bcl-2 were suppressed significantly treated with LJP after 48 h. All of the differences were significant(P <0.05). CONCLUSION LJP has inhibitive effects on the Tu212 cells, this mechanism was probably through inhibition of the proliferation and promotion of the apoptosis.

Objective:
To analyze the clinical characters and surgical treatment of primary parapharyngeal space (PPS) tumors.
Methods:
A total of 23 cases of primary PPS tumors which were treated from November 2011 to December 2017 were included for the retrospective analysis in this study.
Results:
Twenty-three cases of patients with primary PPS tumors were analyzed in this study. Surgical approach was as follows: transcervial approach applied in 7 cases, transparotid approach in 4 cases, transoral approach in 2 cases, transmandibular approach in 4 cases, and the combined approaches on 6 cases. Besides, among 7 cases with upper PPS tumor, we applied the surgical navigation system in the surgery of 3 cases. The mean surgery duration of these cases, 3.5 h, was shorter than unused ones, while the mean maximum size (MMS) of tumors, 5.7 cm, was also larger. So far, 23 cases had no recurrence and metastasis. The most frequent histopathological type of all the cases was pleomorphic adenoma (8 cases), followed by Schwannoma (5 cases). With an 8-to-72-months follow up, 23 cases had no recurrence, metastasis or death.
Conclusions
Surgical resection is preferred in the treatment of PPS tumors. In the upper PPS tumor cases, the surgical navigation system could reduce the operative duration significantly and is more suitable for larger tumors.

Objective:To analyse clinical outcomes and risk factors of vascular crisis on patients received oral and maxillofacial defect repairations with free tissue flap.Methods:From January, 2013 to July, 2018, 1 049 patients with soft tissue defect of oral and maxillofacial were reconstructed with free tissue flap, in which 64 cases occurred vascular crisis. Among the cases, 28 defect were reconstructed with radial forearm free flap (RFFF), 19 with anterolateral thigh flap (ALTF), and 17 with fibula flap. All patients underwent surgical exploration. The clinical data and surgical outcomes were collected. The univariate analysis and multivariate regression analysis were performed by using SPSS version 22.0 software. The result was supposed to statistically significant when P<0.05. Results:Among 64 patients occurred vascular crisis, 44 flaps were rescued successfully by surgical procedures (68.8%). Univariate analysis revealed that the salvage rate was related to the smoking history, type of tissue flap, time of vascular crisis occurrence, cause of vascular crisis and the time interval between crisis occurrence and surgical exploration ( P<0.05). Multivariate regression analysis revealed that only type of tissue flap, the time of vascular crisis occurrence and the interval time were the independent significant factors for salvage rate ( P<0.05). Conclusion:The salvage rate became higher when the vascular crisis occurred earlier, and the interval time was shorter. The type of tissue flap could affect the outcome of surgical exploration. The success rate decreased with an order of RFFF, ALTF to fibula flaps. The primary principle in the management of vascular crisis was early identification and early surgical exploration.
