Biliary tract and pancreatic surgery complicated by acute pancreatitis: a clinical analysis.

Objective: To study the clinical treatment features of biliary tract and pancreatic surgery complicated by acute pancreatitis.

Methods: A retrospective analysis of 21 cases of biliary tract and pancreatic surgery complicated by acute pancreatitis in the Department of General Surgery in our hospital during May 2005 to July 2011 was performed; the clinical treatment features were analyzed in terms of surgical option, onset interval of acute pancreatitis after last surgery, length of stay in hospital and Ranson score.

Results: There was no statistic difference between the two groups (A: The onset interval of acute pancreatitis after last surgery < 0.

Selection of proximal fusion level for degenerative scoliosis and the entailing proximal-related late complications.

Objective: To determine the optimal selection of proximal fusion level for degenerative scoliosis (DS) and investigate the long-term proximal-related complications.

Methods: Profiles of 95 consecutive patients with DS who underwent posterior long instrumented fusion were analyzed retrospectively. Perioperative parameters were reviewed stratified into 3 groups according to the relationship between the upper instrumented vertebrae (UIV), horizontal vertebrae (HV) and upper end vertebrae (UEV), namely HV Group (UIV = HV or above), HV-UEV Group (UIV = between HV and UEV) and UEV Group (UIV = UEV or below) in coronal plane and 3 groups in sagittal plane according to segment levels.

Two novel mutations of ornithine transcarbamylase gene identified from three Chinese neonates with ornithine transcarbamylase deficiency.

We aim to analyze the blood metabolic profiling and the gene mutation of ornithine transcarbamylase (OTC) in three neonates with ornithine transcarbamylase deficiency (OTCD). Three neonates with OTCD were included in this study. The profiling of amino acids and acylcarnitine was determined using MS-MS assay.

Local transplantation of osteogenic pre-differentiated autologous adipose-derived mesenchymal stem cells may accelerate non-union fracture healing with limited pro-metastatic potency.

Fracture non-union is a serious complication in orthopedic clinical practice. Mesenchymal stem cells are believed to play a vital role in fracture healing process. Among various origins of mesenchymal stem cell, adipose derived stem cells hold great promise especially in clinical milieu.

A novel specialized staging system for cancellous fracture healing, distinct from traditional healing pattern of diaphysis corticalfracture?

Metaphysis cancellous bone fracture is one of the most common fracture types in clinical orthopedic practice. The specialized healing process of cancellous bone fracture has long been ignored by the academic society. Comparing with diaphyseal cortical bone healing, cancellous bone healing showed less bone tissue necrosis, barely any hematoma formation, limited inflammation events and no external callus formation.

Safe distance between electrotome and recurrent laryngeal nerve: an experimental canine model.

Background: Various energy based surgical devices (ESD) like electrotome have been widely applied in thyroid surgery. This is the first canine model to determine the safety margin of using the electrotome near the recurrent laryngeal nerve (RLN) to prevent injury to this nerve during thyroid surgery.

Methods: Eighteen healthy male dogs were divided equally into three groups according to the distance between electrotome application and the RLN: Group A (5 mm), Group B (3 mm), Group C (1 mm).

Nucleus pulposus cells derived IGF-1 and MCP-1 enhance osteoclastogenesis and vertebrae disruption in lumbar disc herniation.

Study Design: Chronic strained lumbar disc herniation (LDH) cases were classified into bulging LDH, herniated LDH and prolapse LDH types according to imaging examination, and vertebrae disruptions were evaluated. Cytokines derived from the nucleus pulposus cells were detected, and their effects on osteoclastogenesis, as well as the mechanisms involved, were studied via an in vitro osteoclast differentiation system.

Objective: To clarify the mechanisms of lumbar vertebrae resorption induced by lumbar herniation.

Role of lumbricus extract in the nerve amplification effect during peripheral nerve regeneration.

Among the methods of the peripheral nerve repair, artificial conduit bridging surgery is superior to epineurium and perineurium neurorrhaphy because of supplying enough space for nerve regeneration. Artificial conduit provides important microenvironment for peripheral nerve regeneration, especially for nerve amplification effect. Amplification phenomenon has been demonstrated in many studies using artificial conduit.

Three cases giant panda attack on human at Beijing Zoo.

Panda is regarded as Chinese national treasure. Most people always thought they were cute and just ate bamboo and had never imagined a panda could be vicious. Giant panda attacks on human are rare.

Albuminuria: Prevalence, associated risk factors and relationship with cardiovascular disease.

Aims/introduction: To investigate the prevalence and associated risk factors of microalbuminuria, and to explore the relationship between albuminuria and cardiovascular disease (CVD).

Materials And Methods: A nationally representative sample of 38,203 Chinese participants was categorized by different levels of urinary albumin-to-creatinine ratio (ACR; 0 -10 mg/g, 10 -20 mg/g, 20 -30 mg/g, 30 -300 mg/g). The prevalence of albuminuria was compared by using a single urinary ACR cut-off point and by sex-specific ACR cut-off points.

[Profile analysis and comparison of the Han and Uygur adult in Xinjiang area].

Purpose: To obtain the profile and difference between the Han and Uygur normal adult in Xinjiang area.

Methods: According to the accepted standards, the Han and Uygur college students in Urumqi city were randomly selected for this study. These students were divided into 2 groups according to gender.

Rejection of insulin therapy among patients with type 2 diabetes in China: reasons and recommendations.

Background: Insulin injection therapy is one of the most effective treatments for type 2 diabetes mellitus (T2DM). Many people with T2DM in western countries resist starting insulin therapy; whether the same is true in China is unknown. This survey-based study assessed acceptance and rejection of insulin therapy among individuals with T2DM in China and self-reported reasons for these therapy choices.

Detection of sleep apnea-hypopnea syndrome with ECG derived respiration in Chinese population.

Evaluation of sleep apnea-hypopnea syndrome (SAHS) is mainly based on the polysomnogram (PSG), which is considered as the golden diagnostic criteria. As a novel noninvasive and low cost alternative method to detect SAHS patients, the diagnostic power of ECG-derived respiration (EDR) hasn't been well determined. In light of this, we tested whether EDR can be utilized as a feasible tool to diagnose SAHS in Chinese patients.

Efficacy and safety of exenatide once-weekly vs exenatide twice-daily in Asian patients with type 2 diabetes mellitus.

Aims/introduction: To compare safety and efficacy of the extended-release formulation exenatide once weekly (EQW) vs exenatide twice daily (EBID) for 26 weeks in type 2 diabetes patients from China, India, Japan, South Korea and Taiwan.

Materials And Methods: A randomized, comparator-controlled, open-label study included 681 patients with type 2 diabetes inadequately controlled (hemoglobin A1c [HbA1c] ≥7 and ≤11%) with oral antihyperglycemic medications (OAMs). Patients added 2 mg EQW or 10 μg EBID to current OAMs.
