Exertional heat stroke (EHS) is an emergency with a high mortality rate, characterized by acute onset and identification difficulties. EHS prevention focuses on evaluating the environment by professionals, making preventive measures in advance, identifying internal and external risk factors for the onset of disease, carrying out prior heat adaptation and endurance training, monitoring the status of high risk persons in real time. After occurrence of EHS, the key to success treatment is on-site accurate identification and diagnosis and rapid implementation of effective cooling measures, thus winning time of EHS patients transferred to the hospital for the treatment. This article reviews the current status of EHS prevention and treatment in domestic and foreign from the scene to the hospital. Summarizing the recognition, diagnosis, cooling measures, treatment concepts and principles of EHS, we hope to provide a reference for the rescue of EHS in hospital and outside.

Pancreatic cancer is a common malignancy of gastrointestinal system, with features of early metastasis, easy invasion to adjacent tissues and organs and neural metastasis. Therapies include surgery, chemotherapy, radiotherapy, physi-cal and biological therapy and so on. Surgical management, including radical resection and palliative operation, is a major approach. Radiotherapy and chemotherapy could improve the resectional rate and decrease the tumor dissemination. Physical and biological therapies are widely recommended, and there is a rapid progress in zoopery. However, the efficacy of all the thera-pies is far from satisfactory. Recently, the therapy consisting of surgical resection, radiotherapy, chemotherapy, physical and biological therapy in increasing the long-term survival rate and improving the life quality of patients, along with combined thera-py has attracted the attention of surgeons.

Primary liver cancer is the fourth most common malignancy and the second most common cause of cancer death in China, posing a serious threat to the health of Chinese people. Hepatocellular carcinoma (HCC) represents more than 90% of primary liver cancers, among them 66% of patients are with intermediate-advanced HCC. Therefore, prevention strategies and conversion therapies to patients with intermediate-advanced HCC are particularly important. Hepatic arterial infusion chemotherapy (HAIC) is one of the important treatment methods to treat intermediate-advanced HCC. The tumor objective response rates and surgery conversion rates of HAIC-based conversion therapies are promising. The authors review the history of HAIC and the HAIC-based conversion therapies in this article.

Objective To study the reference range of umbilical artery blood gas and the significance of umbilical artery blood pH on the diagnosis of neonatal asphyxia. Methods Five thousand six hundred and eleven live-births new born in our hospital were consecutively enrolled. The following five items related to birth asphyxia were recorded including antepartum high-risk factors, Apgar scores, umbilical artery blood pH, organ damage, and differential diagnosis on the causes of low Apgar score. Reference range of umbilical artery blood gas, the correlations between the umbilical artery blood pH and the other items were analysed. Results The reference range of umbilical artery blood gas ((x|-)?2s) were pH 7.00 - 7.40, PaO2 0.34 - 6.10 kPa, PaCO2 3.43 - 10.03 kPa, BE 1.5 - - 18. 5 mmol/L. The umbilical artery blood pH was negatively correlated with organ damage (r = - 0. 99,P

0.05). After operation, in the pedicle screw fixation group the indexes were restored, but the restoration was lost gradually at later follow- up stage. Their superior- inferior endplate angle before operation averaged 19.5? , but 8.6? after operation, and 20.0? at the latest follow- up. Their wedged angle before operation averaged 20.7? , but 9.1? after operation, and 15.9? at the latest follow- up. In the non- pedicle- screw fixation group, the indexes decreased gradually at the later follow- up. Their average superior- inferior endplate angle before operation was 16.6? , 14.6? after operation, and 23.0? at the latest follow- up. Their average wedged angle before operation was 15.6? , 16.6? after operation, and 22? at the latest follow- ups. Conclusions The height of the fractured vertebra may be lost and the wedged vertebra may occur again after surgery but conditions may become stable in 2 years. The spinal kyphosis deformity, however, may go on. Its possible causes are structural changes of the vertebra after surgery, the early degenerative changes of the adjacent intervertebral discs, and osteoporosis.

Objective To evaluate the effect of early limited fluid resuscitation in treatment of severe pelvic fracture accompanied with traumatic hemorrhagic shock. Methods A retrospective study was done on 96 patients with severe pelvic fractures accompanied with traumatic hemorrhagic shock admitted into hospital from January 2002 to December 2006. Of all, 55 patients ( routine resuscitation group)were dealt with routine fluid resuscitation and 41 (limited resuscitation group) with limited fluid resuscitation. The injury severity, degree of shock, start time of resuscitation, transfusion volume were statistically analyzed and compared in two groups. Results Routine resuscitation group received transfusion volume of (3 432 ± 1 156) ml, with cure rate of 64% and mortality rate of 36% ; while limited resuscitation group received transfusion volume of (2 685 ± 524) ml, with cure rate of 83% and mortality rate of 17%. There was statistical difference between both groups ( P ＜ 0.05 ). Conclusion Limited fluid resuscitation can improve cure rate of severe pelvic fracture accompanied with traumatic hemorrhagic shock.

Objective To explore the classification and surgical management of pancreatic duct stones.Methods The clinical data of 54 patients with pancreatic duct stones who were admitted to the People's Hospital of Hunan Province from June 1994 to November 2009 were retrospectively analyzed. Stones were found in the head of the pancreas (type Ⅰ ) in 31 patients, in the body and tail of the pancreas (type Ⅱ ) in 7 patients, and in all the pancreas (type Ⅲ ) in 16 patients. According to the types of the pancreatic duct stones, ten patients (6 with type Ⅰ , two with type Ⅱ and two with type Ⅲ pancreatic duct stones) received opening of the main pancreatic duct + pancreaticojejunostomy or pancreaticogastrostomy ( group A). Twenty-four patients ( 16 with type Ⅰ and eight with type Ⅲ pancreatic duct stones) received pancreaticoduodenectomy (group B). Fifteen patients (nine with type Ⅰ and six with type Ⅱ pancreatic duct stones) received subtotal resection of pancreatic head preserving duodenum (group C). Five patients with type Ⅱ pancreatic duct stones received resection of the body and tail of the pancreas and the spleen (group D). All data were analyzed using the t test. Results The mean operation time, blood loss, length of postoperative stay and hospital charges of group A were (2.2 ± 1.2)hours,( 127 ±24)ml,( 11.4 ±4.3) days and (3.24 ± 1.15 ) × 104 yuan, respectively. Five out of nine patients who were followed up had stone recurrence. The mean operation time, blood loss, length of postoperative stay and hospital charges of group B were (7.6 ± 1.1 ) hours, (409 ± 37 ) ml, ( 18.9 ± 2.5 ) days and (7.93 ± 1.35 ) × 104 yuan, respectively.No stone recurrence was detected in the 21 patients who were followed up. The mean operation time, blood loss,length of postoperative stay and hospital charges of group C were (4. 1 ± 0.7 ) hours, ( 156 ± 63 ) ml, ( 10.3 ±2.1 )days and (4. 12 ± 1.22) × 104 yuan, respectively. No stone recurrence was detected in the 15 patients who were followed up. The mean operation time, blood loss, length of postoperative stay and hospital charges of group D were (3.3 ± 1.4) hours, ( 185 ± 36 ) ml, ( 9.3 ± 2.0) days and ( 3.22 ± 1.05 ) × 104 yuan, respectively. No complication was detected after the operation, and no stone recurrence was detected in the three patients who were followed up. There were significant differences in the mean operation time, blood loss, length of postoperative stay and hospital charges between patients with type Ⅰ and Ⅲ pancreatic duct stones who received pancreaticoduodenectomy and subtotal resection of pancreatic head preserving duodenum (t = 12. 143, 14. 099, 11. 550, 9. 103,P < 0.05 ). Conclusions Classification of the pancreatic duct stones is important for choosing the proper surgical procedure. Subtotal resection of pancreatic head preserving duodenum is ideal for the treatment of patients with type Ⅰ or Ⅱ pancreatic duct stones.

Objective To investigate the effects of continuous invasive mechanical ventilation combined with BAL on COPD patients with respiratory failure. Methods Sixty COPD patients with respiratory failure were divided into BAL and control group randomly. Control group were treated with sputum suction tube to aspire sputum and BAL group treated with BAL. The changes in the indicators were observed. Results The SpO2, airway peak inspiratory pressure and blood gas analysis were improved significantly compared with the control group (P < 0.01). The number of peripheral blood leucocytes and the level of CRP in BAL group were lower than those in control group at the seventh day (P < 0.01). The duration of invasive mechanical ventilation and hospital stay in BAL group was shorter than that in control group (P < 0.01) and there was no severe complication in both groups. Conclusion BALwith continuous mechanical ventilation support are safe and effective and shorten hospitalization time and improve the prognosis of COPD patients with respiratory failure.
