Although the origin of Chinese medicine was well recorded inHuang-Di Nei-Jing, different opinions, however, now existed in the authenticity of discussions on five cardinal directions in theYi-Fa Fang-YiLun. From the perspective of regional systems, this paper began with the local culture of Chinese northern nomadic people, analyzed their fire using custom, moxibustion therapy, ice and snow culture and Shamanistic witchcraft. The purpose was to reveal that moxibustion therapy originated from Shamanistic witchcraft and medical practice of the northern nomadic people.

Acetazolamide, a sulfonamide-derived medication, is frequently used in the treatment of various types of glaucoma. But this kind of medicine is associated with acute angle closure glaucoma. This paper is a review for the researches of this rare adverse reaction at internal and abroad. It can prompt more ophthalmologists to understand and pay attention to this rare adverse reaction of acetazolamide and sulfonamides derived drugs. Then the doctor will make accurate diagnosis, timely treatment and grasp the right operation opportunity and reduce the occurrence of postoperative complications ultimately.

Objective Severe preeclampsia (sPE), which is usually complicated by small-for-gestational-age (SGA) and immature labor , remains a leading cause of maternal and neonatal mortality and morbidity. This study was to investigate the risk factors of SGA in sPE. Methods We retrospectively analyzed 100 cases of sPE, 35 with SGA (the case group) and the other 65 without it ( the control group ) .We conducted single-factor analysis on the general characteristics and potential impact factors of the patients , i-dentified the independent risk factors of SGA using the un-conditional stepwise logistic model , and assessed the value of umbilical arter-y S/D ratio and proteinuria ration in the diagnosis of sPE with SGA with the ROC curve . Results Compared with the control group , the case group had more cases of early-onset sPE ( P =0.010 ), earlier gestational and delivery weeks (P<0.001), lower neonatal weight at birth ( P<0 .001 ) , higher rate of admission to and longer stay in the neonatal ICU (P<0.001), and higher incidence of neo-natal complications (P<0.05).The case group also showed signifi-cant increases in comparison with the control in the umbilical artery S/D ratio (2.95 ±0.75 vs 2.31 ±0.47, P<0.05), frequency of S/D ratio ≥95th percentile (22.86% vs 6.15%, P<0.01), and rate of proteinuria ≥5 g/24 h (42.86% vs 20.00%, P<0.05).The S/D ratio ≥95th percentile (OR=6.02, 95%CI:2.32-16.78) and proteinuria≥5 g/24 h (OR=1.65, 95%CI:1.56-3.01) were found to be the risk factors of sPE with SGA.The area under the curve was 0.852 for the combination of S/D ra-tio and proteinuria ration in the diagnosis of sPE with SGA (P<0.05). Conclusion Umbilical artery S/D ratio≥95th percentile and proteinuria ≥5 g/24 h contribute to the early prediction, prevention, and prognosis of sPE, and is valuable for the diagnosis of sPE with SGA.

Objective: To evaluate the efficacy and safety of acupuncture for the treatment of knee osteoarthritis and to provide evidence for its use in clinical practice. Methods: Eight databases were extensively searched up to March 2018. Randomized controlled trials (RCTs) comparing the efficacy of acupuncture with sham acupuncture or no acupuncture for knee osteoarthritis were included. Study selection, data extraction and quality assessment were independently conducted by two reviewers. The Cochrane Collaboration's tool was used for assessing the risk of bias. Results: A total of 18 RCTs were included, involving a total of 3522 participants. The results showed that acupuncture was superior to sham acupuncture in relieving pain (SMD=-0.34, 95％CI:-0.57 to -0.11, I2=85％, P=0.003) and improving physical function (SMD=-0.34, 95％CI: -0.57 to -0.11, I2=85％, P=0.003). In comparison to the no-acupuncture group, the acupuncture group also showed significant advantages in relieving pain (SMD=-0.79, 95％CI: -1.15 to -0.43, I2=87％, P<0.0001) and improving physical function (SMD=-0.75, 95％CI:-1.19 to -0.31, I2=91％, P=0.0008). Sensitivity analyses suggested that the results were robust, and Egger's test found no potential publication bias. Conclusion: In the treatment of knee osteoarthritis, the acupuncture group had significant advantages over sham acupuncture or no-acupuncture groups in relieving pain and improving physical function.

The optic-fiber sensor technology combined with near-infrared diffuse reflection spectroscopy was applied to directly analyze Peganum harmala and identify different origin of P. harmala on the basis of principal component analysis, clustering analysis, SIMCA method, which resulted in the establishment of a new method to rapidly and nondestructively identify the origin of P. harmala. The original full wavelength spectrum for principal component analysis and the score of first two principal components can distinguish four origins of P. harmala basically. In the wavelength range of 866-2,507 nm, MSC as pretreatment method to establish the best model of clustering analysis to forecast the samples with the accuracy of 91.67%, can distinguish the four origins of P. harmala while in the wavelength of 1,085-2,507 nm, normalization method as pretreatment methods to establish a best model of SIMCA to forecast the sample, all the samples except for the changji sample have been identified with a total recognition rate of 97.22%. The results show that using near infrared diffuse reflectance spectroscopy combined with SIMCA is the best method that can be effectively used to identify the P. harmala.

Surface lubricity is one of the important performance criteria for interventional guide wire. In this paper, a review of the methods of surface hydrophilicity and lubrication modification of interventional guide wire is presented, including their fundamental principles, effects and some relative applications. These methods all have their own advantages and disadvantages, therefore, limitations of experimental conditions need to be taken into account.

Acute respiratory distress syndrome (ARDS) patients experiencing protective mechanical ventilation, is associated with a marked mortality reduction. However, the incidence of acute cor pulmonale (ACP) in ARDS patients has recently been reported to range between 22% and 25%, as well as a trend for higher mortality. Therefore, the mechanical ventilation strategy is proposed, not only based on the protection of the lung, but also focused on the impact on the right ventricle function. Currently, point-of-care ultrasound has been widely practiced in a variety of clinical setting, which plays more and more important role in the early detection and management of ARDS and its complications. A retrospective study concerning the incidence, pathophysiology and risk factors for ACP patients in ARDS was done to analysis the application of lung ultrasound and echocardiography combined with lung ultrasound in clinical hemodynamics monitoring, and so as to optimize the ventilation setting to protect the function of lung and right ventricle. Further exploration of effective improvement of the pulmonary vascular and right ventricle function the goal-directed ultrasound approach, and the diagnosis and treatment flow is expected.

Hemorrhagic transformation(HT) is the most severe complication after tissue-type plasminogen activator (tPA) thrombolysis. It greatly limits the clinical application of tPA. Early blood-brain barrier ( BBB) damage may be an important mechanism for HT. Maintaining the integrity of BBB can significantly decrease the risk of HT. This article review s the roles, mechanisms, and preventive measure of early BBB damage in HT after tPA thrombolysis.

Total knee arthroplasty is an important means of knee joint terminal disease , however , it has not been fully ob-served that there exists hidden blood loss in perioperative period , which greatly affects the function of patients with postoperative reha-bilitation exercise , increases the length of hospital stay , and increases the hospitalization expense .There is an urgent demand to im-prove patient satisfaction recovery .To avoid the perioperative blood loss that brings patients the adverse effects on postoperative rehabil -itation, we systemically reviewed the reviews of hidden blood loss after total knee replacement and analyzed the mechanism of hidden blood loss and its influencing factors .
