Through investigating the hospital admission and hospital discharge of vagrant mental patients in Xi-aoshan Hospital from January 2011 to December 2015 , the present study found that there existed some ethical di-lemmas including the risk ofdiagnosing mental disorder but actually not, lack of the guarantee of patients' rights and interests and supervision mechanism without guardian, long-term retention in the wards, and so on. It is sug-gested to establish right protection and supervision committee for vagrant mental patients, reduce the misdiagnosis ofdiagnosing mental disorder but actually not through the error correction mechanism, ensure proper treatment and care, create retention way, protect the basic rights of the vagrant mental patients, reduce mental disability, avoid to stray again, so as to perfect the social management system.

Objective To investigate the impact of diabetes on coronary artery bypass grafting (CABG)in peroperative patients. Methods Clinical data of 692 CABG patients were collected retrospectively from Sep. 2006 to Jul. 2010. The CABG patients were divided into diabetic group (n = 276) and nondiabetic group (n = 416) according to with the status of diabetes or not before operation. Blood glucose was dynamicaly monitored and treated with insulin to control blood glucose in perioperativeperiod. The postoperative effect,perioperative complication and inhospital case fatality and their relationship with diabetes were analyzed using univariate analysis. Results No significant differences were found regarding the incision complications (5. 8%vs. 4. 3 % , P > 0. 05). The volume of blood transfusion was (890. 7 ± 520. 6) ml in the diabetes group, which was not significantly different from that of (825. 2 ±518. 4)mlin the non-diabetes group (P>0. 05). No significant difference was found on cardiac arrhythmia (13.0% vs. 13. 5%),renal function insufficient (5. 1% vs. 2.4%)and case fatality (2. 9% and 1. 9%) between the diabetes and non-diabetes group (Ps >0. 05). In the diabetes group and non-diabetes group, the duration of IABP (3.7 ± 1. 6) d vs (3.5 ± 1.6)d, use of ventilator (2. 6 ± 1.9)d vs. (2. 4±1.5)d were not sigfnificantly different (Ps >0.05). The length of hospital stay and cost were (22. 0 ±8. 8)d and (8. 11 ±2. 40) thousand RMB in the diabetes group, which were significantly higher than that of (20. 6 ±7. 6)d and (7. 63 ±2. 20) thousand RMB in the non-diabeties group (t =2. 22 and 2. 71 ,Ps <0.05) . Conclusion There are no significant differences in the operative case fatality and complications between patients with diabetes and without nondiabetes. However,diabetes increases hospital stay and expense.

Objective To evaluate the detection rates of colorectal polyps and cancer in the elderly and characterize the pathological features of the colorectal neoplasm in DongLi District in Tianjin.Method Totally,46 743 subjects aged 60-74 were recruited from the national colorectal cancer screening program,including subjects registered from November 2012 to April 2013 in DongLi District in Tianjin.Each subject completed a questionnaire and a fecal occult blood test.Colonoscopies were conducted in 434 subjects with high risk for colorectal cancer.Results Among all the subjects,2 880 were at high risk for colorectal cancer which accounts for 6.16％ (2 880/46 743) of the total subjects.Among the subjects who underwent the colonoscopy,165 (men:105,women:60) were colorectal polyps accounting for 5.73％ (165/2 880)in the total risk,with 51 subjects (1.77％) advanced neoplasms and 4 subjects (0.14％) cancer.The detection rates of colorectal polyps is 0.35％ (165/46 743),and colorectal cancer is 8.6/105(4/46 743).More polyps were found on the left colon compared with the right.More tubular adenoma was found compared with the other pathological types.Most of the polyps were smaller than 0.5 cm.Colorectal polyps and advanced neoplasms were more frequent in men than women [45.45％ (105/231) vs 29.56％ (60/203),16.02％ (37/231) vs 6.90％ (14/203),all P ＜ 0.01].Multiple polyps (P ＜ 0.05) and polyps with diameter larger than 1.0 cm (P ＜ 0.01) were more often in men than in women.Men tended to have more colorectal polyps in right colon and higher detection rate for moderate or sever atypical hyperplasia than women(all P ＜ 0.05).Conclusion There is a higher incidence of colorectal polyps in the elderly.It is important to establish the national sequential colorectal cancer screening program for the early diagnoses of colorectal polyps and cancer in the elderly.

Objective To explore the surgical methods for the treatment of the total anomalous pulmonary venous connection (TAPVC) and choices to prevent related complications.Methods We analyzed retrospectively the clinical data of 24 cases with TAPVC admitted to our hospital from Jan 2006 to Dec 2011,including 15 male and 9 females with the age range of 50 d-14 years.There were 10 cases younger than six months,accounting for 41.7％ (10/24).The average body weight was (9.30 ± 3.96) kg.There were 8 cases 33.3％ (8/24) had a body weight of below 10.00 kg.Among the patients,16 cases (66.7％,16/24) were supracardic type,6 (25.0％) were cardiac type,and 2 (8.30％) were intracardiac type.For the treatment of the upracardiac type,5 cases were treated through the right atrium and interatrial septum incision path;Eleven cases were through the left atrial anastomosis.For the treatment of the cardiac type,the right atrial incision was used for coronary vein antrum isolation,and the patch was carefully packaged to separate the coronary sinus openings into the left atrial side.For the 2 cases of the intracardiac type,heart was slightly lift towards the right,and the venous anastomosis was performed for the left atrial posterior wall and the summary vein,and the vertical vein was then ligated.Results No surgery-related death occurred.Reoperation was performed for 1 patient occurred pulmonary edema due to pulmonary venous obstruction induced two days post-surgery.Condition was improved after the extension of left atrial side as the patient was found to have anastomotic stenosis.Postoperative arrhythmia were observed in 7 cases (29.2％,7/24),including 3 nodal arrhythmia (12.5％,3/24) and 4 (16.7％,4/24) atrial arrhythmia.Patients were followed up for 4-24 months.All children during the follow-up period were in good condition.They had significantly improved activity tolerance compared with pre-surgery.Chest X-ray showed clear markings free of congestion.Conclusion Appropriate surgical approach and routes could help improve the success rate of surgery treatment of TAPVC and reduce postoperative complications,thus achieving good therapeutic effect.

Objective:To analyze the clinical features and SCN4A gentic background of a family with hypokalemic periodic paralysis.Methods:Peripheral blood samples and clinical data were collected from the proband, his brother and parents, and genomic DNA was extracted from these blood samples. Genome-wide exome sequencing was conducted to determine the mutation site in the proband and then allele-specific oligonucleotide primers were designed based on the mutation site. Polymerase chain reaction (PCR) was performed to detect the mutation site to further identify the causative gene in the family.Results:The patient was a 19-years-old male, Han nationality. The patient presented with periodic paralysis while hypokalemia at the same time. His father and grandpa have a similar medical history in the family. A hybrid missense variation (p.R672H) was identified in exon 12 of SCN4A gene in the proband. The same mutation was also detect in the proband's father.Conclusions:The heterozygous missense variation of SCN4A gene (p.R672H) found in this study resulted in familial hypokalemic periodic paralysis. Our research provided reference for the future genetic counseling of this patient and enriched the research data on the relationship between genotype and clinical manifestations.

Objective: To explore the role of tentorium cerebelli hiatusincision in treating severe and most severe brain injuries complicated by tentorial herniation.Methods: From July 1994 to July 1999 tentorium cerebelli hiatus incision was done based on intracranial hematoma evacuation and bone flap craniectomy decompression in 70 cases of severe and most severe brain injuries complicated by tentorial herniation.Results: Of the 70 cases, GCS 3-5 was in 23 and GCS 6-8 in 47; satisfactory recovery in 39 cases (55.7%), moderate disability in 12 (17.1%), severe deficit in 6 (8.6%), vegetative survival in 4 (5.7%) and 8 (11.4%) died.Conclusions: Tentoriun cerebelli incision is helpful in alleviating secondary brain stem injury from tentorial herniation and in reducing the disability and death rate of the patients.

Objective:To explore the mechanism of potassium iodide-induced pyrolysis of thyroid follicular cells.Methods:Thyroid gland tissue was obtained from patients with thyroid cancer (TC) coexisting with Hashimoto′s thyroiditis, and the tumor-adjacent Hashimoto′s thyroiditis tissue was used as the control. ELISA was used to detect the concentration of the pyroptosis inflammatory cytokines interleukin (IL)-1β and IL-18 in the tissues, and Western blotting was used to detect the activation of gasdermin (GSDM) proteins, a biomarker for pyroptosis. Thyroid follicular cells treated with different concentrations of potassium iodide, and IL-1β, IL-18, lactate dehydrogenase (LDH), GSDMD were measured. Transcriptome chip analysis was used to explore the differentially expressed genes involved in pyroptosis of thyroid follicular cells induced by potassium iodide treatment.Results:The levels of IL-1β and IL-18 cytokines in the tissues of patients with Hashimoto′s thyroiditis and thyroid cancer were higher than control tissues ( P<0.01), and the activation of the pyroptosis executive protein GSDMD was significant increased, while GSDME was not activated. IL-1β, IL-18, and LDH secretion were significantly increased in response to potassium iodide stimulation in thyroid follicular cells ( P<0.01) and GSDMD was cleaved, which indicated that potassium iodide induced the pyroptosis of thyroid follicular cells. Moreover, potassium iodide could activate NLRP3 inflammasomes to promotethe pyroptosis of thyroid follicular cells. Transcriptome chip analysis further found that PARP1 protein was highly upregulated by the stimulation of potassium iodide, and then enhanced the activity of nuclear factor-κB (NF-κB) transcription factor to induce pyroptosis. Conclusions:The findings in this study reveal that potassium iodide promotesthe pyroptosis of thyroid follicular cells through activating NF-κB-NLRP3 inflammasome, which may be a novel mechanism that promots the development of Hashimoto′s thyroiditis under the condition of excessive iodine intake. PARP1 is a pivotal protein that mediates the pyroptosis induced by potassium iodide and may be a potential therapeutic target to control Hashimoto′s thyroiditis progression.

Osteoporotic proximal humeral fracture (OPHF) is one of the common osteoporotic fractures in the aged, with an incidence only lower than vertebral compression fracture, hip fracture, and distal radius fracture. OPHF, secondary to osteoporosis and characterized by poor bone quality, comminuted fracture pattern, slow healing, and severely impaired shoulder joint function, poses a big challenge to the current clinical diagnosis and treatment. In the field of diagnosis, treatment, and rehabilitation of OPHF, traditional Chinese and Western medicine have accumulated rich experience and evidence from evidence-based medicine and achieved favorable outcomes. However, there is still a lack of guidance from a relevant consensus as to how to integrate the advantages of the two medical systems and achieve the integrated diagnosis and treatment. To promote the diagnosis and treatment of OPHF with integrated traditional Chinese and Western medicine, relevant experts from Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine have been organized to formulate Expert consensus on the diagnosis and treatment of osteoporotic proximal humeral fracture with integrated traditional Chinese and Western medicine ( version 2024) by searching related literatures and based on the evidences from evidence-based medicine. This consensus consists of 13 recommendations about the diagnosis, treatment and rehabilitation of OPHF with integrated traditional Chinese medicine and Western medicine, aimed at standardizing, systematizing, and personalizing the diagnosis and treatment of OPHF with integrated traditional Chinse and Western medicine to improve the patients ′ function.

Traumatic cerebrospinal fluid leakage commonly presents in traumatic brain injury patients, and it may lead to complications such as meningitis, ventriculitis, brain abscess, subdural hematoma or tension pneumocephalus. When misdiagnosed or inappropriately treated, traumatic cerebrospinal fluid leakage may result in severe complications and may be life-threatening. Some traumatic cerebrospinal fluid leakage has concealed manifestations and is prone to misdiagnosis. Due to different sites and mechanisms of trauma and degree of cerebrospinal fluid leak, treatments for traumatic cerebrospinal fluid leakage varies greatly. Hence, the Craniocerebral Trauma Professional Group of Neurosurgery Branch of Chinese Medical Association and the Neurological Injury Professional Group of Trauma Branch of Chinese Medical Association organized relevant experts to formulate the " Chinese expert consensus on the diagnosis and treatment of traumatic cerebrospinal fluid leakage in adults ( version 2023)" based on existing clinical evidence and experience. The consensus consisted of 16 recommendations, covering the leakage diagnosis, localization, treatments, and intracranial infection prevention, so as to standardize the diagnosis and treatment of traumatic cerebrospinal fluid leakage and improve the overall prognosis of the patients.
