AIM: To introduce a new kind of wrist-hand orthosis.METHODS: The major frame of wrist-hand orthosis is composed of dorsal carpal guard plate and carpal bracket; while, a U-shaped anterior bracket is fixed on the anterior side of the major frame. Ferrules of index finger, middle finger, fourth finger and little finger respectively connect to dorsal carpal guard plate of the major frame via elastic brace; ferrule of thumb is fixed on one side of ferrule of index finger by using steel wires; an abduct elastic sleeve is designed on the lateral dorsal carpal guard plate of ferrule of little finger by using steel wires. According to experimental demands, wrist with the palms upward or downward puts into the major frame, which is composed of dorsal carpal guard plate and carpal bracket. The hand is anterior to the major frame; ferrules are located over rolling sleeve by forward and fingers are located below the rolling sleeve by forward; ferrules are respectively rang the index, middle, fourth and little fingers; ferrule of thumb is rang the thumb. Continuously, wrist rotates based on orthopaedic demands to realize various orthopaedic functions.RESULTS: The wrist-hand orthosis is used to help the hand maintain extension after extensor tendon injury operation in order to restrict active areas of fingers and promote healing of injured side. On the other hand, this new orthosis is also used to help wrist joint and digital joint maintain flexion after extensor tendon injury operation in order to improve flexion and extension of wrist joint, enlarge active area of flexion of wrist joint, enlarge drifting active area of radialis of wrist joint, and increase muscle strength of radial flexor muscle, ulnar flexor muscle, extensor carpi radialis muscle, extensor carpi ulnaris muscle, extensor carpi ulnaris muscle, flexor carpi ulnaris muscle, extensor digitorum communis muscle, superficial flexor muscle and deep flexor muscle.CONCLUSION: The wrist-hand orthosis refers to protection of wrist and hand after operations of nerve, tendon, muscle and vessel injuries and recovery of motor dysfunction of wrist joint and digital joint induced by wrist-hand fracture; on the other hand, this new orthosis can improve active area of wrist joint and strengthen muscle force.

Capillary leak syndrome (CLS) is a common and life-threatening disorder in children.The common pathogenies are sepsis,severe trauma,shock,asphyxia,extracorporeal circulation,ischemical reperfusion injury and so on.It is characterized by shock resulting from leakage of plasma,which is refected by accompanying hemoconcentration,hypoalbuminemia and edema,sometimes followed by multiple organ dysfunction syndrome.Clinicians should consider the diagnosis in patients with unexplained edema and hypotension.To know the pathophysiology and clinical course will be benefit to proper medicine choosen.

Objective To observe the effect of scalp and body acupuncture plus occupational therapy on the upper-limb function in remission stage of cerebral stroke.Method Forty patients in the remission stage of cerebral stroke were randomized into a treatment group and a control group, 20 cases in each group. The two groups both received scalp and body acupuncture plus conventional physiotherapy, while the treatment group was additionally given occupational therapy. Fugl-Meyer Assessment Scale (FMA) and Modified Barthel Index (MBI) were adopted to evaluate the upper-limb function.Result The FMA and MBI scores increased significantly in both groups after the intervention (P<0.05); the increases of FMA and MBI in the treatment group were superior to those in the control group (P<0.05).Conclusion Scalp and body acupuncture plus occupational therapy can improve the upper-limb function in the remission stage of cerebral strokeand improve the activities of daily living.

Objective To explore the clinical significance of detecting serum interleukin (IL)-6 in patients with esophageal squamous cell carcinoma(ESCC).Methods We detected the serum level of IL -6 in 35 patients with ESCC(observation group)and 35 healthy controls (control group)by double antibody sandwich enzyme -linked immunosorbent assay(ELISA),and then analyzed its clinical value.Results The serum levels of IL -6 in the observation group (27.66 ±2.30)ng/L was significantly higher than (17.72 ±3.62)ng/L in the con-trol group (t =11.63,P <0.01).There was significant difference in the serum level of IL -6 in the observation group preoperation and postoperation [(27.66 ±2.30)ng/L vs (23.62 ±3.27)ng/L,t =5.12,P <0.01].The serum level of IL -6 in the observation group preoperation was relevant with clinical stages(χ2 =11.15,P <0.01).Conclusion The change of serum IL -6 level in patients with ESCC is related to the occurrence and development of ESCC,which is an important indication for diagnosis and prognosis.

Objectives: To find out influencing factors of quality of life(QOL) of staffs in Centers for Disease Prevention and Control(CDC),whose results would be taken as theoretical evidence for government policy-makers to work out strategy of health human resources.Methods: The WHO Quality of Life Brief Scale(WHOQOL-BREF) was employed as the assessing tool for staffs of CDC who were in a city and its neighborhood counties.Each subject was asked to complete a spot self-assessment.Results: There is no significant difference of QOL of staffs between city and neighborhood county.Working at different departments was one of the influencing factors on psychological and social domains.Harmonious family relationship,good appetite,agreement to work competition,and confidence in working institutes were influencing factors to the total score of QOL.Conclusions: Scores of QOL of CDC staffs were relatively low with various influencing factors.It is necessary for leaders of related departments to take countermeasures to improve the QOL of CDC staffs.

In medical researches,large-scale collaborations spanning institutions and disciplines have emerged a key pattern for tackling major research subjects.Contract writing for medical research collaboration,as a legal means to address the rights and obligations of the parties,should be fair,reasonable,scientific and strict as much as possible.The author probed into problems found in current writing of medical research contracts,and came up with corresponding remedies.

To create a novel kind of orthosis to correct the dysfunction of antebrachium, wrist, metacarpus and digit and to facilitate the protection and functional training after injury of forearm and hand. The orthosis is constituted of a cardinal shelf, a stem shelf of metacarpophalangeal joint, a front bracket, finger ferrules, elastic strings and steel wires. The cardinal shelf is composed of a backplate for dorsal palm and a bracket for wrist with a U-shaped rack fixed in front of it. Ferrules of index finger, middle finger and fourth finger and little finger are connected to the backplate on the cardinal shelf through elastic strings. The thumb ferrule is set outside the ferrule of index finger on the backplate with steel wires. Another ferrule that is used to enclose the wrist and antebrachium is linked to the crossbar of the U-shaped rack through elastic strings. This orthosis plays an effective role in the protection of nerves, tendons, extremity of vascular anastomosis and the prevention of allotopia after fracture due to different trainings. It can improve the range of motion of wrist joint, metacarpophalangeal joint, and articulationes interphalangeae and strengthen the muscle power of pronator teres, pronator quadratus, supinator, wrist extensor, wrist flexor, extensor digitoium, perforans manus and musculus flexor digitorum sublimes. This orthosis could be applied for patients after the operation of antebrachium,wrist and manus to promote the recovery of their functions.

Objective:To investigate the false alarm rate of electrocardiogram monitor, and to develop methods to exclude interference. Methods:A total of 52 patients in emergency room in hospital in March 2014 were in the control group. The frequency and causes of false alarms of the electrocardiogram monitor were recorded. At the meantime, the improvements were analyzes. A total of 52 patients in emergency room in hospital in May 2014 were chose to be the experimental group. The frequency and causes of false alarms of the electrocardiogram monitor were recorded after some improvements. Results: In control group, the total of alarms rate were 5376 times, including 2208 times of false alarms. The false alarm rate was 41.07%. While in the experimental group, there were 2634 alarms, including 798 times of false alarms. The false alarm rate was 30.29%. Compared to the control group(x2=25.77, P<0.05). It was statistically significant difference.
