We reviewed the modern development of clinical application and experimental reseach on the prescription Biejiajian Wan (BJ), which are the basement that we will study its anti-renal fibrosis. At present, the prescription BJ is mainly applied to the treatment of chronic heptic desease. Its experimental reseach is mainly confined to the studing of anti-heptic fibrosi. Refering the scientific and technological result of anti-heptic fibrosis, we think the prescription BJ would have the effection of anti-renal fibrosis on the basis of theory of planning treatment according to diagnosis. But it has not been reported to the prescription BJ on the clinical and experimental reseach on anti-renal fibrosis. Therefore, it is very important to take on clinical reseach of the prescription BJ and discuss the effecting mechanism of anti-renal fibrosis from the level of integration, cell and molecule, which will help to enlarge the clinical application of the prescription Biejiajianwan and explained the essence of "persistent diseases injuring collateral branch of large channel" in traditional Chinese medicine.

Objective To study the clinical characters, treatment modalities and prognosis of patients with maxillary squamous cell carcinoma. Methods The clinical data of 60 patients with maxillary squamous cell carcinoma treatment between January 1994 and December 2004 were analyzed retrospectively.The patients were treated with three therapy modalities including radiotherapy alone(22 cases) ,radiotheraphy and surgery( R +S, 29 cases)and concurrent chemo-radio-therapy adjuvant surgery (CCR + S, 9 cases).Results The five year survival rate were 18.2%, 51.7% and 33.3% for patients in the radiotherapy alone group, the R + S group and the CCR + S group, respectively. Patients receiving R + S combined modality therapy had a significantly higher five year survival rate than the patients who were treated radiotherapy alone ( λ2 = 15.62, P <0.01 ). The five year survival rate(51.7% ) of patients in R + S group was significantly higher than that (33. 3% ) of patients in CCR + S group ( λ2 = 4. 28, P < 0.05 ), and also higher than that ( 18. 2% ) of patients in radiotherapy group( λ2 =9.49 ,P <0. 01 ). Conclusions The combined therapy of radiation and surgery was a good choice of treatment for the patients with maxillary sinus squamous cell carcinoma. The role of concurrent chemo-radiotherapy adjuvant surgery in the treatment of maxillary sinus squamous cell carcinoma needs further to research.

Objective To study the clinical characteristics, the surgical treatments and the prognostic factors of medullary thyroid carcinoma. Methods Eighty-two cases of medullary thyroid carcinoma undergoing surgeries between January 1999 and December 2004 were reviewed. There were 39 males and 43 females. Age ranged from 16 to 77 years old, with a median of 46 years old. The calcitonin, chronogranin A and neuron-specific enolase were analysed by immunohistochemistry in samples,and calcitonin was detected in 24 cases. Of them, 28 cases underwent lobectomy with isthmectomy, 24 for remained lobe dissection, 16 for total thyroidectomy, and 14 only for neck and upper mediastinal lymph node dissection. Of the 82 cases, 68 cases underwent trachea esophageal ditch dissection, 53 for unilateral neck dissection, 11 for bilateral neck dissection, 13 for upper mediastinal lymph node dissecion through transcervical approach, and 5 for mediastinal lymph node dissecion through inverted T-shaped incision. Results Immunohistochemical examination revealed that the expression rates of calcitonin, chronogranin A and neuron-specific enolase were 95.8%, 88.9% and 80. 0% respectively. Total metastasis rate of neck lymph nodes was 68.8%, and the rates in level Ⅱ, Ⅲ, Ⅳ, Ⅴ andⅥ were 27.3%, 47.7%, 59.1%, 11.4% and 52.3% respectively. The overall five-year survival rate was 87.8%. The recurrent rate of contralateral lobes was 5.8% and local recurrent rate was 7.3% respectively. Univariate analysis showed that gender, age and TNM stage were significant prognostic factors. Multivariate analysis revealed that distant metastasis was an independent prognostic factor. Conclusions Standard radical surgery of the primary and metastatic lesion is key to the treatment of medullary thyroid carcinoma. Lobectomy with isthmectomy should be applied to sporadic medullary thyroid carcinoma, with regular postoperative follow-up, and total thyroidectomy to familial or bilateral medullary thyroid carcinoma. Therefore. detecting the calcitonin is very imoortant for medullary thyroid carcinoma patients' prognosis.

Objective:To evaluate the efficacy of acute T-cell lymphoblastic leukemia(T-ALL)in children and explore the prognostic risk factors.Methods:The clinical data of 127 newly diagnosed children with T-ALL admitted to five hospitals in Fujian province from April 2011 to December 2020 were retrospectively analyzed,and compared with children with newly diagnosed acute precursor B-cell lymphoblastic leukemia(B-ALL)in the same period.Kaplan-Meier analysis was used to evaluate the overall survival(OS)and event-free survival(EFS),and COX proportional hazard regression model was used to evaluate the prognostic factors.Among 116 children with T-ALL who received standard treatment,78 cases received the Chinese Childhood Leukemia Collaborative Group(CCLG)-ALL 2008 protocol(CCLG-ALL 2008 group),and 38 cases received the China Childhood Cancer Collaborative Group(CCCG)-ALL 2015 protocol(CCCG-ALL 2015 group).The efficacy and serious adverse event(SAE)incidence of the two groups were compared.Results:Proportion of male,age ≥ 10 years old,white blood cell count(WBC)≥ 50 × 109/L,central nervous system leukemia,minimal residual disease(MRD)≥ 1％during induction therapy,and MRD ≥ 0.01％at the end of induction in T-ALL children were significantly higher than those in B-ALL children(P＜0.05).The expected 10-year EFS and OS of T-ALL were 59.7％and 66.0％,respectively,which were significantly lower than those of B-ALL(P＜0.001).COX analysis showed that WBC ≥ 100 x 109/L at initial diagnosis and failure to achieve complete remission(CR)after induction were independent risk factors for poor prognosis.Compared with CCLG-ALL 2008 group,CCCG-ALL 2015 group had lower incidence of infection-related SAE(15.8％vs 34.6％,P=0.042),but higher EFS and OS(73.9％vs 57.2％,PEFS=0.090;86.5％vs 62.3％,PoS=0.023).Conclusions:The prognosis of children with T-ALL is worse than children with B-ALL.WBC ≥ 100 × 109/L at initial diagnosis and non-CR after induction(especially mediastinal mass has not disappeared)are the risk factors for poor prognosis.CCCG-ALL 2015 regimen may reduce infection-related SAE and improve efficacy.

Purpose To investigate the value of application of D2-40/CD34-CK cocktail antibodies by double immunohistochemical staining for assessment of lymphovascular invasion (LVI) and to determine its prognostic significance in colorectal cancer with insufficient lymph node harvest. Methods Specimens from 133 cases of colorectal cancer with less than 12 lymph nodes were selected. HE staining and double immunohistochemical staining of the cocktail antibodies were performed to compare the difference of the two methods in screening for LVI. The The relationship between LVI confirmed by cocktail antibody immunohistochemical staining and clinicopathological characteristics and overall survival (OS) of patients was analyzed. Results (1) The detection rates of cocktail antibody double immunohistochemical staining and HE staining for LVI were 42.9％ (57/133) and 21.8％ (29/133) with statistically significant difference (P < 0.001). (2) The presence of LVI confirmed by double staining was significantly associated with Dukes staging, depth of invasion, clinical stages, lymph node metastasis and tumor budding (P < 0.05). (3) The presence of LVI, the location and extent of LVI, and the number of tumor cells in thrombus ≥5.5 for cases with LVI ≤2 clusters, were significantly associated with OS (P < 0.05). Conclusion D2-40/CD34-CK cocktail antibodies double staining is superior to routine HE staining in assessing LVI. LVI is intimately associated with tumor stage, lymph nodes metastasis and tumor budding, and it is an independent prognostic factor for CRC patients. It should be a supplementary examination for these patients with insufficient lymph node harvest.

OBJECTIVE: This study aimed to investigate the effect of occlusal thickness design on fracture resistance of endocrowns restored with lithium disilicate ceramic and zirconia. METHODS: A total of 24 artificial first mandibular molars were randomly divided into four groups with six teeth in each group as follows: group lithium disilicate ceramic-2 mm (lithium disilicate ceramic, with an occlusal thickness of 2 mm and a retainer length of 4 mm); group lithium disilicate ceramic-4 mm (lithium disilicate ceramic, with an occlusal thickness of 4 mm and a retainer length of 2 mm); group zirconia-2 mm (zirconia, with an occlusal thickness of 2 mm and a retainer length of 4 mm); and group zirconia-4 mm (zirconia, with an occlusal thickness of 4 mm and a retainer length of 2 mm). After adhesive cementation (RelyX Ultimate Clicker), all specimens were subjected to thermocycling (10 000 cycles). The specimens were subjected to fracture resistance testing at a 135° angle to the teeth at a crosshead speed of 0.5 mm·min⁻¹ in a universal testing machine. Data were analyzed with ANOVA and Tukey's HSD test by SPSS 15.0. The failure modes were classified. RESULTS: The fracture resistances of groups lithium disilicate ceramic-
2 mm, lithium disilicate ceramic-4 mm, zirconia-2 mm, and zirconia-4 mm were (890.54±83.41), (2 320.87±728.57), 
(2 258.05±557.66), and (3 847.70±495.99) N respectively. Group zirconia-4 mm had the highest fracture resistance, whereas group lithium disilicate ceramic-2 mm had the lowest. CONCLUSIONS The fracture resistance of molar endocrown with zirconia is higher than that with lithium disilicate ceramic. Increasing the occlusal thickness can improve the fracture resistance but increase the risk of fracture of abutment.

Objective::To investigate the processing purpose of Morindae Officinalis Radix (MO), Euodiae Fructus (EF) and Polygalae Radix (PR) processed by Glycyrrhizae Radix et Rhizoma (Gly). Method::The content of dapsone in rat plasma was determined by high performance liquid chromatography (HPLC), the mobile phase was acetonitrile (A)-water (B) for gradient elution (0-5 min, 10%-25%A; 5-20 min, 25%A) and detection wavelength was set at 292 nm. PK Solution 2.0 software was used to simulate pharmacokinetic parameters. Result::Within 300 min after dapsone was administrated, compared with the control (CTL) group, the elimination of dapsone was slowed down and its plasma concentration was increased in the unprocessed product of MO (UMO) group. The elimination of dapsone was accelerated and its peak concentration (C_max) was decreased in the processed products of MO with Gly (GMO) groups, and they had positive correlation with proportion of Gly in GMO. Compared with the CTL group, the elimination of dapsone was slowed down, and its plasma concentration was increased and its peak time (T_max) was postponed in the unprocessed product of EF (UEF) group, while their C_max and T_max were changed in the processed products of EF with Gly (GEF) groups. Compared with the CTL group, the elimination of dapsone was slowed down and its plasma concentration was increased in the unprocessed product of PR (UPR) group, while the elimination was accelerated and its plasma concentration was decreased in the processed products of PR with Gly (GPR) groups. Conclusion::The elimination of dapsone is slowed down in rats administered with UMO, UEF and UPR, while its elimination is accelerated in rats administered with the processed products of these three herbs with different proportions of Gly. Among the proportions, effect of processed products of these three herbs with 100∶6 (ratio of unprocessed product-Gly) on pharmacokinetics of dapsone is not significant.
