Clinical observation on Tongluoyuzufang Ⅰ for patients with diabetic foot / 重庆医学

Objective To observe the clinical efficacy and its mechanism of Tongluoyuzufang Ⅰ in patients with diabetic foot (DF).Methods A total of 60 cases with DF was randomly divided into experimental group and control group,30 cases in each group.All patients were given insulin and/or hypoglycemic drugs and other Western medicine comprehensive treatment to control blood sugar steadily.The control group received methylcobalamin treatment,and the experimental group received Tongluoyuzufang Ⅰ therapy treatment based on the methylcobalamin treatment.Both groups were treated for 4 weeks for a course of treatment.The clinical efficacy,ankle-brachial index,nerve conduction velocity,hemorheology,blood lipid,serum cytokines and adverse reactions before and after treatment were compared after 3 courses of treatment.Results After treatment,the total effective rate was 90.0 ％ in the observation group,higher than that in the control group(x2 =5.963,P＜0.05).After treatment,the ankle-brachial index,nerve conduction velocity,hemorheology and blood lipid level in both groups were significantly improved(P＜0.05).After treatment,serum levels of tumor necrosis factor-α(TNF-α) and vascular endothelial growth factor(VEGF) in both groups were significantly decreased,while the levels of anti-thrombin Ⅲ (AT-Ⅲ) has increased(P＜0.05).The improvement of the indexes in the observation group was better than that in the control group(P＜0.05).There were no serious adverse events during treatment.Conclusion Tongluoyuzufang Ⅰ can significantly improve limb ischemia and nerve conduction function in patient with DF.

18F-deoxyglucose positron emission tomography and MRI in the diagnosis of cervical lymph node metastasis from rabbit nasopharyngeal VX2 carcinoma / 中华放射肿瘤学杂志

Objective To study 18F-deoxyglueose positron emission tomography computed tomo graphy(18 FDG PET-CT) in the diagnosis of cervical lymph node(LN) metastasis from rabbit nasopharyngeal VX2 carcinoma.Methods Nasopharyngeal VX2 carcinoma model using 30 rabbits was established. 18 FDG PET-CT,MRI and pathological diagnosis were performed and compared.ResultsFifty-three cervi cal LNs were picked up from resected specimens of 30 rabbits with nasopharyngeal VX2 carcinoma.There were 42 pathologically confirmed positive LNs.Positivity rate was significantly correlated with the volume and the shortest diameter of the LNs (r = 9.18,P =0.007 ; r = 2.77,P = 0.008).The diagnostic sensitivity of PET-CT was 96% (24/25) and 29% (5/17) for LNs with volume >0.5 cm3 and ≤0.5 cm3 ,83% (25/30) and 33% (4/12) for LNs with the shortest diameter ≥0.5 cm and < 0.5 cm,respectively.The diagnostic sensitivity,specificity and accuracy of PET-CT was 69% (29/42) ,100% (11/11) and 95% (40/42) ,com paring with 60% (25/42) ,91% (10/11) and 83% (35/42) of MRl,respectively.The volume measured by PET-CT images was not significantly different from the pathologically measured volume (t =-1.23,P = 0.233) ,while the volume measured by MRI was significantly different from the pathologically measured vol ume (t =-3.99,P = 0.001).Conclusions The sensitivity,specificity and accuracy of PET-CT are better than those of MRl,especially for the cervical lymph nodes with volume >0.5 cm3 or the shortest diameter ≤ 0.5 cm.PET-CT also can be used to detect the smaller metastatic lymph nodes,though the false negative rate is higher.

Treatment of laryngeal granuloma / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To study treatment method of laryngeal nonspecific granuloma.@*METHOD@#Twenty-five patients with histopathologically identified laryngeal nonspecific granuloma were retrospective reviewed from 1998-2005. All patients were surgically treated by laser laryngomicrosurgery under general anesthesia, postoperative non-operative therapies included anti-gastroesophageal reflux medication, topical inhalant steroid (Beclometasone, Fluticasone) and voice therapy. Two patients were treated with 12 Gy of low-dose radiotherapy after surgery.@*RESULT@#Laryngeal nonspecific granuloma have remarkable tendency of recurrence despite of surgery and non-surgical managements. Recurrence of laryngeal nonspecific granuloma occurs between 2-3 months postoperatively and requires repeated operation for 3 5 times. For intubation granuloma, 6 out of 8 were healed. Six out of eight contact granulomas were healed. Six of gastroesophageal reflux granulomas were healed. Glottic carcinoma was demonstrated in one case after 2 sessions of combined managements. Two patients were completely healed by low-dose radiotherapy of 12 Gy.@*CONCLUSION@#Laryngeal nonspecific granuloma have an obvious tendency of recurrence, however, surgery is an important therapy. Combined non-surgical therapies (anti-gastroesophageal reflux medication, topical inhalant steroid and voice therapy) are necessary. In case which routine ways fail to control recurrence, low-dose radiotherapy is recommended because of its safety and satisfied effect.

Hypofractionated three-dimensional conformal radiotherapy for primary liver cancer with portal vein tumor thrombosis / 中华放射肿瘤学杂志

Objective To evaluate the efficacy of hypofractionated 3DCRT for primary liver cancer(PLC) with portal vein tumor thrombosis(PVTT).Methods Between April 1999 and August 2003,34 PLC patients with PVTT received hypofractionated 3DCRT.The severity of hepatic cirrhosis was 23 in Child-Pugh gradeA and 11 gradeB.The median value of GTV was 773?cm~3(105-2097?cm~3).The radiotherapy regimen consisted of 38-63?Gy in 7-15 fractions with 4-8?Gy per fraction(median value 5?Gy),the treatment was delivered 3 times per week during every other day.Results Having response rate(CR+PR) of 76%(26/34),the overall 1-,2-,and 3-year survival rate at was 36%,19% and 13%,respectively.Conclusion Hypofractionated three-dimensional conformal radiotherapy is effective for primary liver cancer with portal vein tumor thrombosis.
