Objective@#To analyze the condylar and inclination of the occlusal plane features in skeletal Class Ⅲ malocclusion patients with mandibular asymmetry by using cone beam computed tomography(CBCT).@* Methods@#Forty eligible patients with Angle Class Ⅲ malocclusion were enrolled. All individuals were classified based on the distance from Me point to median sagittal plane. The left and right angles between OP and FH plane, the position and morphology of the condyle were measured in both groups.Then the data collected were statistically analyzed. @* Results@#Compared to the opposite side, there was a statistically significant difference(P<0.05) in angle between OP and FH plane, the anterior joint space, superior joint space, lateral joint space and condylar mediolateral diameter, with a higher proportion of joint posteriority in deviated side. Mandibular deviations were positively correlated with both the anterior joint space of the deviated side and the angle between OP and FH plane of the opposite side(P<0.01). There was no statistical difference between the left and right side of angles between OP and FH plane, the position and morphology of the condyle in skeletal Class Ⅲ patients without mandibular deviation(P>0.05); the joint was predominantly in anterior and middle position. @*Conclusion@#There is asymmetry on the left and right sides of the inclination ofocclusal plane, the position and morphology of the condyle of skeletal Class Ⅲ malocclusion patients with mandibular asymmetry. Compared with the opposite side, the deviated side has smaller angle between OP and FH plane and smaller condylar mediolateral diameter, and the condyle shows generally more posterior, inferior and inward movement in glenoid fossa. The inclination of the occlusal plane and the position of condyle are significantly and positively correlated with the distance from Me point to median sagittal plane.

ABSTRACT
Many studies have found a correlation between suicidal behavior (SB) and anhedonia, the main symptom of depression, in terms of both psychological and neurophysiological findings. The purpose of this review is to find the relationship between the two neuroimaging mechanisms, and to provide help for the future study of how the brain imaging changes can promote the mechanism of SB in depression patients with anhedonia symptoms. This review also emphasizes the necessity of intervention for the symptoms of anhedonia when preventing depression from committing suicide. The latest research results were reviewed about anhedonia in depression and magnetic resonance imaging of SB.The results showed that the default network, insula, lateral orbitofrontal gyrus, anterior cingulate gyrus, ventral striatum gyrus, ventral lateral and dorsolateral prefrontal gyrus, thalamus and habenula nucleus were dysfunction in depression with state anhedonia symptoms, affecting SB in terms of mood, execution, reward and aversion processing, especially the low lethal SB.
ABSTRACT
Objective:To investigate the pathological spectrum and variation of adult renal biopsies in People's Hospital of Xinjiang Uygur Autonomous Region from 1986 to 2020.Methods:The pathological data of 5 652 adult renal biopsies from August 1986 to December 2020 were retrospectively collected, and characteristics of pathological spectrum were analyzed. Regarding every 5 years as a research stage, the whole period was divided into 7 stages to analyze the pathological features and variation of renal biopsies. The first stage (P1) started from August 1986 to December 1990. The second stage (P2) started from January 1991 to December 1995. The third stage (P3) started from January 1996 to December 2000. The fourth stage (P4) started from January 2001 to December 2005. The fifth stage (P5) started from January 2006 to December 2010. The sixth stage (P6) started from January 2011 to December 2015. The seventh stage (P7) started from January 2016 to December 2020.Results:The age was (36.47±14.86) years old (18-83 years old) in 5 652 renal biopsies. There were 2 961 males (52.39%). There were 5 636 cases of autologous kidney biopsy and 16 cases of transplanted kidney biopsy. The descending order of incidence classified by disease types were primary glomerular disease (PGD, 4 470 cases, 79.31%), secondary glomerular disease (SGD, 994 cases, 17.64%), tubular-interstitial disease (160 cases, 2.84%), and hereditary nephropathy (12 cases, 0.21%). IgA nephropathy (IgAN, 1 573 cases, 35.19%) was the most frequent pathologic type of PGD, followed by membranous nephropathy (MN, 1 028 cases, 23.00%), mesangial proliferative glomerulonephritis (MsPGN, 878 cases, 19.64%), minimal change disease (MCD, 427 cases, 9.55%), and focal segmental glomerulosclerosis (345 cases, 7.72%). Lupus nephritis (LN, 251 cases, 25.25%) was the most common type of SGD, followed by hypertension nephropathy (193 cases, 19.42%), diabetic kidney disease (168 cases, 16.90%), purpura nephritis (138 cases, 13.88%), and ischemic nephropathy (90 cases, 9.05%). IgAN was the most common type of primary glomerulonephritis and mainly occurred in the age group of 18-59 years old. PGD was the most common glomerular disease in Han nationality (78.33%), Uygur nationality (81.72%) and other ethnic (77.15%) groups. Using Bonferroni correction method, the incidence of PGD in Uygur nationality was higher than that in Han nationality ( P<0.017). From P1 to P7, the detection rates of MN and MCD were increased in common renal pathological types, meanwhile, the ratio of MsPGN was decreased (all P<0.05). From P5 to P7, the detection rates of MN in Han nationality and Uygur nationality increased in the common pathological types of PGD, meanwhile, the ratio of MsPGN decreased (all P<0.05). LN was the most common SGD. The incidence of LN in females was higher than that in males ( P<0.001). Using Bonferroni correction method, the incidence of SGD in Uygur nationality was lower than that in Han nationality ( P<0.017). There was no significant variation in the common pathological type of SGD in Han and Uygur nationalities. Chronic rejection was the main pathological type of transplanted kidney biopsies. Conclusions:PGD is the main type of kidney disease spectrum in People's Hospital of Xinjiang Uygur Autonomous Region. IgAN is the most common PGD and mainly occurrs in the age group of 18-59 years old. As time goes by, the proportion of MN and MCD is increased, meanwhile the proportion of MsPGN is decreased significantly. LN is the most common SGD.
ABSTRACT
【Objective】 To analyze and evaluate the application of intelligent voice call technology (IVCT) in the recall of lost blood donors, so as to provide references for the intelligent development of blood donor recruitment. 【Methods】 SMS, human telephone and IVCT were used to recall the lost blood donors from 2016 to 2018, and the recall results were statistically analyzed. 【Results】 20 406 blood donors were recalled from August 20 to December 30, 2020 through 1 029 human telephones, 7 571 automated calls, and 11 806 SMSs, and 4.81%(32/665), 3.44%(51/1 484) and 1.17%(138/11 806) of them responded. There was no significant difference in the recall effect between human telephones and automated calls. The one-year-lapsed blood donors responded about 3 times of those lapsed for 2~4 years (5.97/2.02). 【Conclusion】 The application of IVCT can make up for the shortages of high demand, much interference and long time consuming of human telephones, reduce the labor intensity, improve the efficiency of blood donor recruitment, and promote the recall of lapsed blood donors.
ABSTRACT
The aim of this study is to evaluate the application of carbon nanoparticle lymphatic tracer in total thyroidectomy and bilateral Central District's thyroidectomy for papillary thyroid carcinoma. Sixty-four patients with cN0 papillary thyroid carcinoma that primary treated were random divided into two groups: Trial group and control group. Carbon nanoparticles suspension was injected into the thyroid gland of trial group patients.After ten minutes, total thyroidectomy plus bilateral central neck dissection was performed in the all patients. The black stained tissue in the dissection specimen of trial group was separated. The control group underwent total thyroidectomy plus bilateral central neck dissection. Total lymph node and parathyroid gland in the black stained tissue，and non-black stained tissue in the central compartment dissection specimen of trial group and central compartment dissection specimen of control group were counted respectively.Total lymph node, the mis-cut parathyroid glands in the adipose tissue of central lymph node，post-operative blood calcium and parathyroid hormone（PTH）of two groups were contrasted and analyzed. There are 235 lymph nodes in the black-stained tissue of central compartment dissection specimen of trial group.No parathyroid gland was found in the black-stained tissue.Five lymph nodes and 2 parathyroid glands were found in the non-black stained tissue of central compartment dissection specimen of trial group. There were 164 lymph nodes and 9 parathyroid glands in central compartment dissection specimen of control group. There is statistic difference between the number of lymph nodes in black stain tissue and that of control group（=8.291, =0.000）.Rate of staining lymph node were 97.9 percent. No parathyroid glands were found in the black stained tissue. Nine mis-cut parathyroid glands（7.0%） were observed in the control group，while 2（1.6%） in the trial group（<0.05）.None permanent hypocalcemia and PTH decrease were observed in the two groups.There were 10 patients（31.3%） with temporary hypocalcemia and 9 patients（28.1%）with temporary PTH decrease respectively in the control group，and there was 1 patient（3.1%） and 1 patient（3.1%） respectively in the trial group（<0.05）. The effect of nano-carbon is ideal, and the parathyroid gland can not be stained black. It can distinguish the thyroid tissue from the surrounding lymphoid adipose tissue and clearly mark the Central District lymph nodes, reduce the risk of parathyroid gland injury during thyroid cancer. Neck dissection in the central region can improve the efficiency of lymph node dissection, protect the parathyroid gland and reduce the risk of postoperative complications.
ABSTRACT
Preventive treatment of diseases is a traditional Chinese medicine (TCM) concept that conforms to the demand of modern healthcare emphasizing prevention. This concept, however, calls for close and orderly collaboration between general hospitals and primary community healthcare institutions, in order to encourage coordinated regional development. The authors described the new healthcare mode of " One Center, One Platform, and One Network" jointly built and run by Dongguan Municipal Health Bureau and Dongguan TCM Hospital. This practice has pioneered a full-range, closed-loop and one-stop service chain featuring preventive treatment. Such an innovative TCM health management system has realized information interconnection of preventive treatment, and upgraded the capacity and effectiveness of community medical services, hence expanding the number of beneficiaries.

ABSTRACT
In recent years, osteoporosis (OP) has become one of the main diseases affecting the health of middle-aged and elderly people in China, and the prevalence of OP has increased significantly. The clinical diagnosis and treatment guidelines for this disease are also constantly updated. The overall principles speciallyemphasise that doctors and patients need to work together to negotiate the details of the diagnosis and treatment guidelines, in order to improve the OP clinical diagnosis and treatment rate. Therefore, patients′ knowledge of the disease, understanding of clinical guidelines, and cooperation with doctors to implement diagnosis and treatment plans are very important. In this study, from the most concerned issues of the patients, we established the OP patient practice guideline working group. 14 recommendations, as the OP patient practice guidelines, are proposed in accordance with the relevant principles of the "World Health Organization guidelines development manual" and the international normative process.
ABSTRACT
In recent years, the clinical guidelines for the diagnosis and treatment of rheumatoid arthritis (RA) have been constantly updated. Among the general principles, it is particularly emphasized that, in order to improve the ratio of treat to target(T2T) of RA, doctors and patients should work together to negotiate the details of the guidelines. Therefore, it is important for patients to further understand the disease and clinical guidelines of RA, and to better cooperate with doctors. This study was based on the most concerned issues of RA patients and international standard procedure of guideline study, we organized the working group and introduce the following 16 recommendations constituting the RA patients′ practice guidelines.
ABSTRACT
Hyperuricemia/gout is a common metabolic disease in China, which is a serious threat to people′s health. In clinical practice, the standardization of prevention and diagnosis and the rate of treat-to-target need to be improved. There is still a lack of education for the patients about the understanding of clinical guidelines, the disease knowledge and the importance of cooperating with doctors to carry out diagnosis and treatment. From the most concerned issues of the patients, we established the hyperuricemia/gout patient practice guideline working group with multidisciplinary physicians and patients. Seventeen opinions, as the hyperuricemia/gout patient practice guidelines, are proposed in accordance with the relevant principles of the "WHO guidelines development manual" , and with the international normative process, aiming to improve the patients compliance, improve the level of health management of the disease.
ABSTRACT
In recent years, the clinical experts consensuses or guidelines of ankylosing spondylitis (AS)/spondyloarthritis (SpA) have been constantly updated, but to better understand and practice, patient self-participation management is one of the key points to improve the level of diagnosis and treatment. Through questionnaire survey of these patients, we screened out the most concerned issues, and established the AS/SpA patient practice guideline working group with multidisciplinary physicians and patients. Fifteen opinions, as the AS/SpA patient practice guidelines, are proposed in accordance with the relevant principles of the "WHO guidelines development manual" , and with the international normative process.
ABSTRACT
Objective To investigate the expressions of BAP1 and TET2 proteins in bone marrow of patients with chronic myelomonocytic leukemia (CMML) and their relationship with the prognosis of CMML. Methods The bone marrow paraffin specimens of 41 cases from 41 adult CMML patients diagnosed by Shanghai Sino-US Joint Leukemia Coordination Group from September 2003 to May 2007 were collected. The immunohistochemistry was used to detect the expressions of BAP1 and TET2 proteins in 41 CMML patients. The expressions of TET2 and BAP1 proteins were also detected by the same method in 40 adult patients with acute myelomonocytic leukemia (AMML) and 20 patients with iron deficiency anemia (IDA) diagnosed at the same time as the comparison. The clinical data of 41 CMML patients were analyzed by using retrospective cohort study. The count data were compared by using chi-square test. The correlation between expressions of BAP1 and TET2 proteins was analyzed by using Pearson correlation analysis. Kaplan-Meier method was used to calculate the survival time, and Log-rank test was used for single factor analysis. Results In 41 CMML patients, the positive expression rate of BAP1 was 31.7％ (13/41), including 28.6％ (8/28) in CMML-1 patients and 38.5％ (5/13) in CMML-2 patients; the positive expression rate of TET2 was 41.5％ (17/41), including 39.3％ (11/28) in CMML-1 patients and 46.2％ (6/13) in CMML-2 patients. In 40 AMML patients, the positive expression rate of BAP1 was 32.5％ (13/40), and the positive expression rate of TET2 was 35.0％ (14/40). In 20 IDA patients, the positive expression rate of BAP1 was 5.0％ (1/20), and TET2 had no positive expression. There was no significant difference in the expressions of BAP1 and TET2 proteins between CMML-1 and CMML-2 patients (χ 2 = 0.40, P = 0.53; χ 2 = 0.17, P = 0.68). There was no significant difference in the expressions of BAP1 and TET2 proteins between CMML and AMML patients (χ 2 = 0.01, P = 0.94; χ 2 = 0.36, P = 0.64). There were significant differences in the positive expression rate of BAP1 and TET2 proteins between hematological neoplastic disease (CMML+AMML) and hematological non-neoplastic disease (IDA) (χ 2 = 6.01, P < 0.05; χ 2 = 11.04, P < 0.01). Pearson correlation analysis showed that there was no correlation between expressions of BAP1 and TET2 proteins (r = 0.35, P = 0.27). Univariate analysis showed that anemia (Hb < 60 g/L), mature monocyte count ≥ 2.0×109/L, neutrophil count (1.5×109/L), abnormal karyotype were associated with poor prognosis for CMML. Protein expressions of BAP1 and TET2 were not related with the prognosis of CMML (χ 2 = 0.28, P = 0.600; χ 2 = 0.53, P = 0.460). Conclusion Both BAP1 and TET2 proteins have high positive expression rates in CMML patients, but the expressions of them are not related to the prognosis.
