The aim of this paper is to apply near infrared spectroscopy techniques to construct a rapid identification method for 8 kinds of mineral Chinese Medicines containing carbonates. The qualitative model using clustering analysis method in OPUS software can identify accurately 8 kinds of carbonate-containing mineral Chinese medicines. The near-infrared quantitative model was established by using partial least squares method (PLS) for 7 mineral Chinese Medicines in which main component is calcium carbonate. Compared with the results by EDTA titration, the established quantitative analysis model for calcium carbonate content showed a good prediction result that when the content is between 47.61% -99.17%, the average relative deviation of the prediction result is 0.24% and the average recovery rate was 100.3%. The results also showed that the model using near infrared spectroscopy can get not only a rapid identification of the 8 mineral Chinese medicines containing carbonates, but also an accurate and reliabe content determination of calcium carbonate for the 7 mineral Chinese medicines which contain the component.

Young female early breast cancer (≤ 40 years) treatment presents unique challenges due to its aggressive features. Using data from the Taiwan Cancer Registry (2007–2017), this study investigated its clinical characteristics, treatment patterns, and prognostic factors. The proportion of young female breast cancer declined from 12% to 8% during the study period.Triple-negative (TN) breast cancer was more prevalent in younger patients, while hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative subtypes increased with age. Stages II and III were observed more frequently in older patients, whereas extremely young patients (20–29 years) exhibited compromised overall and recurrencefree survival. Subtype analysis revealed worse outcomes for TN and hormone receptornegative/human epidermal growth factor receptor 2-positive (HER2+) cases. Treatment patterns showed that targeted therapy was more commonly administered to younger patients with HER2+, while endocrine therapy was used less frequently for HR+ cases, reflecting tolerability and treatment compliance challenges. Future research should focus on optimizing therapeutic strategies and addressing long-term survivorship to enhance care for young women with breast cancer.

OBJECTIVETo investigate the incidence, risk factors and preventative methods associated with chyle leak following complete mesocolic excision(CME) for colon cancer.
METHODSClinical data of 592 patients with colon cancer undergoing CME in the department of Colorectal Surgery in the Fujian Medical University Union Hospital from September 2000 to September 2011 were analyzed retrospectively.
RESULTSChyle leak occurred in 46 patients(7.7%). The incidence of postoperative chyle leak following right CME hemicolectomy was 13.3%(30/226), significantly higher than that after left CME hemicolectomy (4.4%). On univariate analysis, chyle leak following CME was associated with tumor size(P<0.05), tumor location(P<0.01), and lymph nodes harvested(P<0.01). Multivariate logistic regression revealed that tumor location and lymph nodes harvested were independent risk factors associated with chyle leak following CME(P<0.05).
CONCLUSIONSTumor location and lymph nodes harvested are independent risk factors for chyle leak following complete mesocolic excision for colon cancer. When the drainage output suddenly increases after oral intake resumption, the chyle test of ascitic fluid should be performed for early diagnosis and prompt management.

OBJECTIVETo appraise the value of clinical treatment of percutaneous reduction and fixation of osteoporotic fractures for the proximal humerus in a geriatric population.
METHODSPostoperation complication, mortality in hospital and within the first three months postoperation, operation time, blood transfusion requirement, the functional outcome of the shoulder had been analysed and observed in 37 cases for open and closed fixation.
RESULTSClosed reduction provided the benefit of obtaining and holding adequate reduction without the soft-tissue dissection of open reduction and internal fixation. The general complication and mortality in the first three months postoperation in the open reduction and internal fixation cases were more severe than the percutaneous cases.
CONCLUSIONSOpen operation increases the risk of the geriatric population with osteoporotic proximal humerus fracture; percutaneous reduction and fixation may be preferable.

OBJECTIVETo evaluate the safety and feasibility of laparoscopic cylindrical abdominoperineal resection.
METHODSSix patients with rectal adenocarcinoma within 3 cm above the anal verge underwent laparoscopic cylindrical abdominoperineal resection. Transabdominal levator transaction was performed laparoscopically, with no position change during the perineal operation. Pelvic reconstruction was achieved using human acellular dermal matrix mesh in 3 patients.
RESULTSAll the procedures were successfully performed without any intraoperative complications, laparoscopy-associated complications, or conversion to the open approach. The mean operation time was 186.7 minutes and intraoperative blood loss was 101.7 ml. All the specimens had a cylindrical shape with levator muscles attached to the mesorectum and circumferential margins were all negative. No adverse incidence followed the pelvic reconstruction using human acellular dermal matrix mesh.
CONCLUSIONSLaparoscopic transabdominal transection of the levator muscles without position change and pelvic floor reconstruction with human acellular dermal matrix mesh is feasible. This procedure simplifies cylindrical abdominoperineal resection which is aggressively invasive and technically complicated. The oncologic outcomes are acceptable and complications are less.

BACKGROUNDBrain metastasis is one of the most important causes of treatment failure in patients with small cell lung cancer (SCLC). This study was conducted to evaluate the effects of prophylactic cranial irradiation (PCI) on survival and brain metastases for patients with limited stage small cell lung cancer in complete remission.
METHODSFifty one patients with limited stage SCLC in complete remission after chemoradiotherapy were randomly divided into PCI group (n = 26) and control group (n = 25). Patients in the PCI group received PCI at a dose of 25.2 to 30.6 Gy in 1.8 to 2.0 Gy per fraction. The Kaplan-Meier method and Log rank test were used to analyse and compare survival rates, and chi(2) test was used to compare the incidences of cranial metastases in two groups.
RESULTSThere was no significant difference in clinical characteristics of patients such as age, sex, effect of treatment before PCI between the two groups. The incidence of brain metastases was 3.8% in the PCI group in contrast to 32.0% in the control group (chi(2) = 5.15, P = 0.02). The 1, 3, 5-year survival rates were 84.6%, 42.3%, 34.6% respectively in the PCI group and 72.0%, 32.0%, 24.0% respectively in the control group, with no difference between the two groups (chi(2) = 2.25, P = 0.13). No serious sequelae were observed in patients receiving PCI.
CONCLUSIONFor patients with limited stage SCLC responding completely to chemotherapy plus radiotherapy, PCI can decrease the incidence of brain metastases and improve survival rate.

OBJECTIVETo analyze the rationale and feasibility of maxillary reconstruction using free fibula-flexor hallucis longus myofascial flap.
METHODSNine consecutive cases of maxillary reconstruction using free fibula-flexor hallucis longus myofascial flaps from August of 2002 to August of 2003 were reviewed. Data concerning the operation included description of maxillary defect, design of the fibula flaps, recipient vessel and complications.
RESULTSOne flap experienced venous thrombosis after operation, and the flap was salvaged after exploration. All the flaps survived completely with the overall success rate of 100%, as well as the 100% survival of all fibula-flexor hallucis longus myofascial flaps.
CONCLUSIONSMaxillary reconstruction using free fibula-flexor hallucis longus myofascial flap without skin paddle is feasible and reliable.

OBJECTIVETo determine the association between urine transforming growth factor beta(1) (TGF-beta(1)) concentration and long-term renal allograft function.
METHODSPatients undergoing kidney transplantation between August 1, 1999 and June 30, 2001 and survived for one year with normal renal functions were investigated. The blood and urine TGF-beta(1) concentrations were tested at an interval of at least 6 months. Totally 134 patients completed the 3-year follow up investigation. Correlation between their renal functions (creatinine clearance rates) and their urine relative TGF-beta(1) concentrations 1 year after renal transplantation were determined. Of the 134 renal recipients, 16 were diagnosed to have chronic allograft nephropathy (CAN), and their blood and urine TGF-beta(1) concentrations 1 year after renal transplantation were compared with those of the recipients free of CAN.
RESULTSThere was a positive correlation between long-term renal functions (loss of creatinine clearance rates) and in relative concentration of TGF-beta(1) urine 1 year after renal transplantation. The urine TGF-beta(1) concentrations of CAN and CAN-free recipients 1 year after transplantation were 182.7-/+40.2 and 398-/+33.5 pg/mg.Cr, respectively, showing significant differences. The blood TGF-beta(1) concentrations of CAN and CAN-free recipients were comparable (32.1-/+4.7 and 31.9-/+4.8 ng/ml, respectively).
CONCLUSIONUrine TGF-beta(1) is significantly elevated even before the onset of renal dysfunction in patients with CAN, and urine TGF-beta(1) level in early stage after renal transplantation can help predict long-term renal function.
