BACKGROUND:The characteristics of condylar morphology should be first understood in patients with unilateral cleft lip and palate. OBJECTIVE:To investigate the bilateral condylar morphology in adult patients with unilateral cleft lip and palate. METHODS:This study included 25 patients with unilateral cleft lip and palate (study group), and 25 normal volunteers (control group). The upper condylar height, ramal height, condylar height and condylar width were measured on panoramic radiographs. The ratio of the upper condylar height to the ramal height and the ratio of the condylar height to the condylar width were calculated. RESULTS AND CONCLUSION:Compared with the control group, upper condylar height, condylar width, condylar height and the ratio of the upper condylar height to the ramal height were reduced in the study group between the normal and affected sides (P<0.05). Moreover, significant differences in condylar morphology were detected between the two groups. No significant difference in ramal height and the ratio of the condylar height to the condylar width was detected between the two groups (P>0.05). No significant difference in upper condylar height, ramal height, condylar width, condylar height, the ratio of the upper condylar height to the ramal height, the ratio of the condylar height to the condylar width, and condylar morphology was detectable between the normal and affected sides in the experimental group (P>0.05). These data show that adult patients with unilateral cleft lip and palate presented short condylar process and narrow neck, and the condylar process is shorter than ramus, which provides clinical evidence for patients with unilateral cleft lip and palate.

BACKGROUND:Fluorouracil sustained-release agent is a commonly used anti-cancer sustained-release drug, which has a good anti-tumor effect.
OBJECTIVE:To explore the effect of fluorouracil sustained-release agent in the treatment of gastric cancer. METHODS:Literatures concerning the effect of fluorouracil sustained-release agent in the treatment of gastric cancer were retrieved and analyzed. In the paper, we investigated the preventive effect of fluorouracil sustained-release agent against tumor recurrence and metastasis after radical resection, and fol owed up the patients who underwent clinical peritoneal implantation of fluorouracil sustained-release agent. We could determine the effect of fluorouracil sustained-release agent in the treatment of advanced gastric cancer by observing the patient’s symptoms and signs, expression of tumor markers, tumor size and survival rate.
RESULTS AND CONCLUSION:After combination therapy of fluorouracil sustained-release agent and arterial infusion chemotherapy adjuvant therapy, the patient’s symptoms and tumor resection rate were significantly improved. The levels of CEA, CA19-9, CA72-4 in the serum of patients significantly reduced, while the apoptosis and necrosis of tumor cells significantly increased. Fluorouracil sustained-release agent could also reduce tumor metastasis and local recurrence, and improve patient survival.

To further explore the molecular mechanism of triterpenoid biosynthesis and acquire highvalue strain of Sanghuangporus baumii , the Agrobacterium tumefaciens-mediated transformation (ATMT) system was studied. The key triterpenoid biosynthesis-associated gene isopentenyl diphosphate isomerase (IDI) was transformed into S. baumii by ATMT system. Then, the qRT-PCR technique was used to analyze gene transcript level, and the widely targeted metabolomics was used to investigate individual triterpenoid content. Total triterpenoid content and anti-oxidant activity were determined by spectrophotometer. In this study, we for the first time established an efficient ATMT system and transferred the IDI gene into S. baumii. Relative to the wild-type (WT) strain, the IDI-transformant (IT) strain showed significantly higher transcript levels of IDI and total triterpenoid content. We then investigated individual triterpenoids in S. baumii, which led to the identification of 10 distinct triterpenoids. The contents of individual triterpenoids produced by the IT2 strain were 1.76–10.03 times higher than those produced by the WT strain. The triterpenoid production showed a significant positive correlation with the IDI gene expression. Besides, IT2 strain showed better anti-oxidant activity. The findings provide valuable information about the biosynthetic pathway of triterpenoids and provide a strategy for cultivating high-value S. baumii strains.

Objective To identify the blood perfusion characteristics of different kinds of liver cancer and individualize interventional treatment models by color Doppler ultrasound(CDUS) and contrast-enhanced ultrasonography (CEUS). Methods The blood perfusion characteristics of 315 patients with liver cancer comfirmed by pathology were analyzed and classified using CDUS and CEUS. Individual interventional therapy models were selected based on the classification. Therapeutic effects were evaluated by EUS,contrast-enhanced CT(CECT) and DSA simultaneously. Results Liver cancer can be classified by the blood perfusion characteristics from CEUS examination. The individualized interventional treatment models were selected and evaluated according to the characteristics:①Solitary small HCC of diameter ≤3 cm group were treated via percutaneous ethanol injection(PEI),radiofrequency(RF) or percutaneous microwave coagulation therapy(PMCT). Necrosis rates of the lesions were 95.0% - 97.9%, 1 and 3 years survival rates were 98.0% and 87.8% ,respectively. ②Diameter ≤5 cm and lesions ≤3 group were treated with RF or PMCT combined PEI. Necrosis rates of the lesions were 93.7% - 94.8% ,1 and 3 years survival rates were 89.8% and 81.4% ,respectively. ③Diameter ＞5 cm and hypervascular tumor main fed by the hepatic artery group were treated with TACE,PEI combined RF or PMCT. Necrosis rates of the lesions were 71.4% - 73.8%, 1 and 3 years survival rates were 66.2% and 47.6%, respectively. ④ Diameter ＞5 cm and hypervascular tumor fed by double blood supply or accompanied by portal vein tumor thrombus group were treated with selective portal vein embolization(SPVE) based on the above treatments. Necrosis rates of the lesions were 53.3% - 55.6%, 1 and 3 years survival rates were 64.7% and 40.0%, respectively. Conclusions Classifying the blood perfusion characteristics and choosing individualized interventional treatment models by CEUS are of important clinical significance in non-surgical treatment of liver cancer.

Objective To observe the curative effect of sirolimus conversion for liver transplantation patients with chronic renal injury.Methods In 23 recipients of liver transplantation using CNI (19 cases using tacrolimus,and 4 cases using cyclosporine A) with chronic renal injury,the immunosuppressant was converted to sirolimus (SRL).The initial dose of SRL was 4 mg per day and 2 mg at the next day.The blood SRL concentration was determined by using high pressure liquid chromatography.When the valley value of SRL concentration reached a range between 5 to 8μg/L,CNI was withdrawn and MMF (1 g/day) was given simultaneously.The basal values of serum creatinine (Scr),creatinie clearance rate (Ccr) and glomerular filtration rate (GFR) were recorded in the recipients before study,and at 1st,3rd,6th,12th,and 24th month after using SRL,blood SRL concentration,Scr,Ccr and GFR,as well as body weight,blood pressure,blood cells count,liver function (serum bilirubin,albumin and prothrombin time),liver biochemistry (AST,ALT,γ-GT and AKP),blood fat (cholesterol and triglyceride) and urine protein were monitored.At the 12th month after using SRL,the graft liver was biopsied to diagnosis rejection.Results During an average followup period of 29.4 months,there were two deaths.In the remaining 21 cases,the Scr values were (147.40 ± 23.36),(152.60 ± 20.08),(150.20 ± 22.64),( 137.60 ± 18.09) and (138.30 ± 17.04)μmol/L,respectively at 1st,3rd,6th,12th,24th month after using SRL.As compared with basal Scr values [(158.91 ± 29.13) μmol/L],there were statistically significant differences at 1at,12th,24th month (P＜0.05).The Ccr values were (0,97 ± 0.18),(0.99 ± 0.1 4),( 1.00 ± 0.17),(1.07 ±0.29) and (1.14±0.12) ml/s,respectively at 1st,3rd,6th,12th,24th month after using SRL.As compared with basal Ccr value [(0.91 ± 0.14) ml/s],there were statistically significant differences at 1st,12th,24th month (P＜0.05).The GFR values were (0.80 ± 0.15),(0.78 ± 0.11),(0.75 ±0.12),(0.84 ± 0.10) and (0.94 ± 0.13) ml/s,at 1st,3rd,6th,12th,24th month after using SRL.As compared with basal GFR value [(0.71 ± 0.11) ml/s],there were statistically significant differences at 1st,12th,24th month (P＜0.05).The proportion of patients with Scr≤123 μmol/L in 21 cases was 38.1％,33.3 ％,28.6 ％,47.6 ％ and 52.4 ％,respectively at 1 st,12th,24th month (P＜0.05).No rejection cases were observed.Conclusion The immunosuppressant conversion to SRL improves renal function of liver transplantation patients with chronic renal injury,and the conversion cure can not cause rejection.

Objective To approach the effect of telbivudine for preventing recurrence of virus and improving renal function in patients with hepatitis B cirrhosis after liver transplantation with renal insufficiency,and observe the mid-and long-term efficacy.Methods We prospectively researched 17 cases of hepatitis B cirrhosis after liver transplantation with renal insufficiency.Maintenance irnmunosuppression protocol at our centre mainly included calcineurin inhibitor (tacrolimus for 12 cases,and sirolimus for 5 cases).These recipients (n =17) remained under the entecavir (n =10),tenofovir (n =4),lamivudine + adefovir (n =3) for at least 6 months before transformation to telbivudine.We detected HBV-DNA level in serum and ensured no rejection during study,necessarily punctured the graft liver for biopsy to determine if there was rejection.The basal values of blood serum creatinine (Scr) and estimated glomerular filtration rate (eGFR,CKD-EPI formula) were recorded.The Scr and eGFR at 6th month before research and basal values and at 6th and 12th month after telbivudine administration were detected,at the same time the general state and adverse reactions were evaluated.Results During the average follow-up period of 20.2 months,1 patients died.The Ser levels detected in the rest 16 patients were 105.74± 18.24,112.26± 18.67,96.48±22.0 and 89.17± 19.56μμmol/L respectively at 6th month before,basal time and 6th,12th month after telbivudine administration.The eGFR values were 72.56 ± 14.39,66.23 ± 16.61,79.77 ± 20.15 and 83.93 ± 23.67 mL/(minute,m2) at different time points respectively.As compared with the basal value,the Scr and eGFR levels were improved obviously (P＜0.05) at 6th and 12th month after telbivudine administration.The proportion of patients with eGFR ＜60 mL/(min·m2) in 16 cases was 25％,37.5％,12.5％ and 6.3％ respectively at 6th month before,basal time and 6th,12th month after telbivudine administration.The serum creatine phosphokinase level was increased (1 023 IU/L) in 1 patient (6.3％),and decreased after transformation of telbivudine to tenofovir at 3rd month after end of research.No rejection and HBV occurred.Conclusion The telbivudine improves renal function in patients with hepatitis B cirrhosis after liver transplantation with renal insufficiency.Meanwhile,telbivudine prevents hepatitis virus B recurrence.However,large samples of long-term clinical data are needed to further confirm.
