The impact of coronary care unit on mortality from acute myocardial infarction in Hong Kong. A prospective randomized controlled study.

A prospective concurrent study was made on 2 groups of patients suffering from acute myocardial infarction admitted at random into the Coronary Care Unit (CCU) or general wards (GW). After excluding those older than 70 years of age, the two groups were similarly matched according to their ages and clinical severity. Those who were initially treated in the CCU had a higher chance of survival from myocardial infarction as compared with those in the GW. The overall mortality was 15.3% (17/111) and 29.3% (27/92) respectively (P less than 0.02), and the risk of dying in the GW comparing to that in the CCU was 2.3 (95% confidence interval 1.1-4.8). Sudden death was more frequently encountered in those treated in the GW. Our findings strongly support the use of the CCU for patients below 70 years.

The Application of Compatible Points

Point compatibility plays a very important role in clinical treatment, and proper compatible application of points can directly influence the therapeutic effects. Only by knowing the functions of points well, can the proper pair of point be prescribed. As stated in Chinese ancient classics, “Functions of points must be carefully considered before needling” and “Much care and thought should be given to selecting points when various diseases are treated with acupuncture.” Dr. Guo Shouyun, a veteran TCM physician, always pays great attention to the combination of points in her acununcture clinical nractice.     

Reconstruction of distal phalanx defect with microsurgical fascia latae flaps combined with rib and skin graft]

OBJECTIVE: To evaluate the clinical application of microsurgical fascia latae flaps combined with rib and skin graft for reconstruction of the distal phalanx defect. METHODS: The phalanx wounds were sutured together like syndactyly. The autologeous rib was revised to repair the bone defect of distal phalanx. The fascia latae flap was used to cover the bone exposure with microvascular anastomoses and resurfaced by a meshed split-thickness skin graft. RESULTS: 5 cases were treated successfully. The fascia latae flaps were all survived with only skin graft necrosis at the distal end in one case. It was healed spontaneously. CONCLUSIONS: The fascia latae flap is nourished by the desending branch of the lateral circumflex femoral artery. The flaps has a good blood supply and can be easily obtained with a long vascular pedicle. The flap is ideal for the reconstruction of distal phalanx defect when combined with autologeous rib implant and skin graft.     

Immunohistochemical analyses of gastric stromal tumors in Taiwanese.

BACKGROUND AND PURPOSE: Gastrointestinal stromal tumors (GISTs), identified by the presence of CD117 (KIT), were previously classified as gastric and intestinal smooth muscle tumors prior to the availability of immunohistochemical methods. This study evaluated the percentage of GISTs previously diagnosed as gastric smooth muscle tumors in our hospital during an 11-year period. METHODS: A total of 81 surgically resected gastric smooth muscle tumor specimens from 81 patients were collected from January 1986 to December 1997. Immunohistochemical studies were performed on these tumors with antibodies of CD34, CD117, smooth muscle actin (SMA), S-100, and desmin. RESULTS: Among the 81 tumors, 74 (91.4%) were CD117-positive and were classified as GISTs. Among the 74 GISTs, CD34 was positive in 72 tumors (97.3%), SMA was positive in 12 tumors (16.2%), desmin was positive in 5 tumors (6.7%), and S-100 was positive in 4 tumors (5.4%). The 7 tumors classified as non-GISTs had the following immunohistochemical characteristics: 1 was a CD117-negative CD34-positive stromal tumor (GINST) [1/81, 1.2%]; 3 were schwannomas with strong S-100-positive characteristics (3/81, 3.7%); and 3 were smooth muscle tumors with both SMA- and desmin-positive status (3/81, 3.7%). No clear relationship between CD117 or CD34 expression and prognosis was found for these tumors. CONCLUSIONS: The majority (91.4%) of gastric tumors originally diagnosed as gastric smooth muscle tumors were GISTs, except for small groups of smooth muscle tumors and schwannomas.     

Alterations in mammalian target of rapamycin signaling pathways after traumatic brain injury.

In response to traumatic brain injury (TBI), neurons initiate neuroplastic processes through the activation of intracellular signaling pathways. However, the molecular mechanisms underlying neuroplasticity after TBI are poorly understood. To study this, we utilized the fluid-percussion brain injury (FPI) model to investigate alterations in the mammalian target of rapamycin (mTOR) signaling pathways in response to TBI. Mammalian target of rapamycin stimulates mRNA translation through phosphorylation of eukaryotic initiation factor 4E binding protein-1 (4E-BP1), p70 ribosomal S6 kinase (p70S6K), and ribosomal protein S6 (rpS6). These pathways coordinate cell growth and neuroplasticity via dendritic protein synthesis. Rats received sham surgery or moderate parasagittal FPI on the right side of the parietal cortex, followed by 15 mins, 30 mins, 4 h, 24 h, or 72 h of recovery. Using Western blot analysis, we found that mTOR, p70S6K, rpS6, and 4E-BP1 phosphorylation levels were significantly increased in the ipsilateral parietal cortex and hippocampus from 30 mins to 24 h after TBI, whereas total protein levels were unchanged. Using confocal microscopy to localize these changes, we found that rpS6 phosphorylation was increased in the parietal cortex and all subregions of the hippocampus. In accordance with these results, eIF4E, a key, rate-limiting mRNA translation factor, was also phosphorylated by mitogen-activated protein kinase-interacting kinase 1 (Mnk1) 15 mins after TBI. Together, these results suggest that changes in mRNA translation may be one mechanism that neurons use to respond to trauma and may contribute to the neuroplastic changes observed after TBI.
