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 observe the change of sexual function in male kidney transplant recipients.

METHODSSixty married males, aged 26 to 45 years, who had received kidney transplantations at least half a year before and whose serum creatinine (Scr) was under 200 mumol/L, were selected randomly in the study. Sexual functions were reviewed before and after the patients' renal failure and after kidney transplantations. The results were analyzed in Chi-Square test methods.

RESULTSTheir sexual functions, significantly aggravated after renal failure, were improved after kidney transplantations, but failed to return to normal. The recipients had a common worry that their sex lives might affect the renal grafts.

CONCLUSIONSKidney transplantations significantly improve the sexual functions of these renal failure patients. It is quite necessary to provide sexological guidance to kidney transplant recipients and their spouses.

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.

Objective　To investigate the protective effect of calcium antagonist Verapamil (VP) on kidney preservation in HCA solution. Methods　After kidneys were isolated from rabbits, they were perfused and stored in HCA solution or in HCA solution with VP pre-supplement at 4℃ for 24 h respectively. The contents of mitochondrial calcium in renal cells and ATP in renal tissues were measured in every group. Results　The contents of mitochondrial calcium was remarkably higher and ATP significantly lower in the kidneys in HCA solution at 4℃ for 24 h than those just after resection. But these could be inhibited in those storing in the HCA solution with VP pre-supplement. Conclusion　Calcium antagonist VP can protect kidney function during HCA solution preservation by inhibiting calcium intaking into mitochondrium.

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.
