乳管镜下浆细胞性乳管炎的分型及临床研究

目的探讨乳管内窥镜对诊断及治疗浆细胞性乳腺炎的临床价值。方法对250例乳头溢液患者行乳管内窥镜检查,对其中95例浆细胞性乳腺炎患者在乳管内窥镜下对乳管内病变的特点予以分析并加以分型研究。结果95例浆细胞性乳腺炎患者中,Ⅰ型患者21例(22．1％),Ⅱ型患者43例(45．3％),Ⅲ型患者18例(18．9％),Ⅳ型患者13例(13．7％)。非手术治疗83例,症状完全缓解45例,好转38例。手术治疗12例,均病理证实,其中5例伴有中、重度不典型增生。结论乳管内窥镜可以对浆细胞性乳腺炎患者做出明确的诊断,并可对病变乳管进行定位,提示手术指征,使绝大多数患者避免手术,对需要手术活检的患者可缩小手术范围,是临床上一种不可缺少的辅助诊断方法。

The relationship between vitamin D deficiency and diabetic foot ulcer: A meta-analysis

A meta-analysis investigation to measure the relationship between vitamin D deficiency (VDD) and diabetic foot ulcer (DFU). A comprehensive literature inspection till February 2023 was applied and 1765 interrelated investigations were reviewed. The 15 chosen investigations enclosed 2648 individuals with diabetes mellitus in the chosen investigations' starting point, 1413 of them were with DFUs, and 1235 were without DFUs. Odds ratio (OR) in addition to 95% confidence intervals (CIs) were used to compute the value of the relationship between VDD and DFU by the dichotomous and continuous approaches and a fixed or random model. Individuals with DFUs had significantly lower vitamin D levels (VDL) (MD, −7.14; 95% CI, −8.83 to −5.44, P < 0.001) compared to those without DFU individuals. Individuals with DFUs had a significantly higher number of VDD individuals (OR, 2.27; 95% CI, 1.63-3.16, P < 0.001) compared to those without DFU individuals. Individuals with DFU had significantly lower VDL and a significantly higher number of VDD individuals compared to those without DFU individuals. However, caused of the small sample sizes of several chosen investigations for this meta-analysis, care must be exercised when dealing with its values.     

成年女性骶棘韧带区的临床应用解剖研究

目的研究骶棘韧带（sacrospinous ligament,SSL）区的血管神经解剖特点,为骶棘韧带固定术（sacrospinous ligament fixation,SSLF）提供解剖学基础。方法对10具（20侧）成人女性尸体的SSL区进行解剖、观查并测量其与周围血管神经的解剖关系。结果SSL的长度是（52．3±4．2）mm,距离坐骨棘2．5cm处的宽度为（12．0±2．1）mm。大部分臀下血管（15／20）出骨盆前经过SSL外侧一半的后方或紧邻上缘,且大部分（18／20）在近SSL上缘处发出尾动脉,它在SSL上缘处距离坐骨棘（15．7±5．6）mm。阴部神经在坐骨棘内侧从内上向外下斜行跨越SSL背侧进入坐骨小孔,位于阴部内血管的内侧或内上方,在SSL上、下缘其最内界与坐骨棘的距离分别是（23．4±3．6）mm和（15．7±1．3）mm。15个半骨盆中（15／20）找到肛提肌神经,其跨越SSL上缘处与坐骨棘的距离是（39．6±8．3）mm。结论SSLF中,选择缝合SSL距离坐骨棘至少2．5am处、宽度为韧带靠近下缘的1／2、深度为韧带全层厚度的浅层之1／2,即宽度约5mm,深度约1mm,可避免损伤其后方及上缘的血管神经。

Oxygen dynamics at paraspinal muscles during exertion using near-infrared spectroscopy in patients with degenerative lumbar scoliosis

 Oxygen dynamics were measured in both sides of the paraspinal muscles of patients with degenerative lumbar scoliosis. The objective was to investigate the extent of stress by measuring the changes in oxygenation and blood flow volume using near-infrared spectroscopy. There were 44 patients with degenerative lumbar scoliosis (7 men, 37 women) and 11 controls with no scoliosis (2 men, 9 women). The measured recovery time for deoxyhemoglobin indicated the recovery from energy deficit after exercise. The average recovery time of the 11 control subjects was 2.4 ± 0.7 s on the right and 2.4 ± 0.8 s on the left. Among the 44 patients the average recovery time was 3.8 ± 1.8 s on the convex side and 2.1 ± 1.1 s on the concave side. There was a significant difference between the two groups. The recovery time on the concave side in patients was faster than that on the convex side. The results of the current study support the theory that stretching the muscles at the convex side results in chronic increases in the intramuscular compartment and reduced muscular blood flow.

Clinical Application of Layered Anastomosis During Esophagogastrostomy

The aim of this study was to compare the operative results in regard to reducing anastomotic leakage and stricture formation using a newly designed layered manual esophagogastric anastomosis versus a stapler esophagogastrostomy versus the conventional hand-sewn whole-layer anastomosis after resection for esophageal or gastric cardiac carcinoma. From January 2004 to September 2006, a total of 1024 patients with esophageal or gastric cardia carcinoma underwent a layered esophagogastric anastomosis with the assistance of a three-leaf clipper in a single university medical center. The mucosal layers of the esophagus and stomach were sutured continuously with 4/0 Vicryl plus antibacterial suture (polyglyconate). From May 2002 to December 2003, there were also 170 patients and 69 patients who underwent stapler and conventional whole-layer anastomosis, respectively; they served as control groups. The results were analyzed retrospectively. The operative mortality rate was 0.7% in the layered group compared to 5.9% and 7.2% for the stapler group and the whole-layer group (p < 0.01), The anastomotic leakage rates were 0%, 3.5%, and 5.8% for the layered group, stapler group, and whole-layer group, respectively (p < 0.01). All patients were followed postoperatively. Six patients in the layered group (0.6%) developed mild stricture formation compared to 16 patients in stapled group (9.9%) and 5 patients in the conventional whole-layer group (7.8%) (p < 0.01). The application of layered esophagogastric anastomosis could reduce the incidence of anastomotic leakage and stricture after esophagectomy compared with the stapler and whole-layer manual anastomoses. It is easy to apply and could be used as an alternative for esophagogastric anastomosis after resection for esophageal or cardiac carcinoma.

Analysis of heat generation of lithium ion rechargeable batteries used in implantable battery systems for driving undulation pump ventricular assist device

We have developed internal battery systems for driving an undulation pump ventricular assist device using two kinds of lithium ion rechargeable batteries. The lithium ion rechargeable batteries have high energy density, long life, and no memory effect; however, rise in temperature of the lithium ion rechargeable battery is a critical issue. Evaluation of temperature rise by means of numerical estimation is required to develop an internal battery system. Temperature of the lithium ion rechargeable batteries is determined by ohmic loss due to internal resistance, chemical loss due to chemical reaction, and heat release. Measurement results of internal resistance (R(cell)) at an ambient temperature of 37 degrees C were 0.1 Omega in the lithium ion (Li-ion) battery and 0.03 Omega in the lithium polymer (Li-po) battery. Entropy change (DeltaS) of each battery, which leads to chemical loss, was -1.6 to -61.1 J/(mol.K) in the Li-ion battery and -9.6 to -67.5 J/(mol.K) in the Li-po battery depending on state of charge (SOC). Temperature of each lithium ion rechargeable battery under a discharge current of 1 A was estimated by finite element method heat transfer analysis at an ambient temperature of 37 degrees C configuring with measured R(cell) and measured DeltaS in each SOC. Results of estimation of time-course change in the surface temperature of each battery coincided with results of measurement results, and the success of the estimation will greatly contribute to the development of an internal battery system using lithium ion rechargeable batteries.
