OBJECTIVETo investigate the incidence of depression and its etiological factors in patients with cryptorchidism 6-16 years after surgical treatment.

METHODSUsing Self-Rating Depression Scale and Correlation Factor Questionnaire, we investigated the incidence of depression symptoms among 70 patients with cryptorchidism 6-16 years after surgical treatment and another 70 healthy males as controls, and analyzed the related factors of depression symptoms.

RESULTSThe incidence rate of depression symptoms was 50% in the cryptorchidism patients postoperatively, extremely significantly higher than 4.3% in the control group (χ2 = 23.5, P <0.01). Multiple stepwise regression analysis showed that the main risk factors of depression symptoms were worries about natural fertility (F = 15.8992, P <0.01), dissatisfaction with scrotal appearance (F = 4.6003, P <0.05), and the status of being married (F = 4.1002, P <0.05).

CONCLUSIONSymptoms of depression often occur in cryptorchidism patients after operation, and the major etiological factors are infertility, dissatisfaction with scrotal appearance, and the status of being married.

In June 2018, the hyaluronic acid chin augmentation was performed on a 24-year-old female patient in Xi′an Goose Pagoda Beauty Hospital. After surgery, the patient′s left half of the tongue became pale and turned to dark purple thereafter. The patient had pain and discomfort in tongue, accompanying with pharyngeal swallowing difficulty. It was speculated that the refluxed hyaluronic acid from submental artery to the left lingual artery. Hyaluronidase was immediately injected. The thrombolytic, vasodilatory, and prophylactic antibiotic treatment were assisted. After 8 days, the pain of tongue was significantly improved, and the color returned to normal.

Objective To investigate the diagnostic and prognostic value of presepsin for sepsis.Methods Diagnostic accuracy test.The plasma presepsin levels of 57 sepsis patients,64 systemic inflammatory response syndrome (SIRS) patients and 120 healthy individuals admitted to the 263 Clinical Branch,General Hospital of Beijing Military Region between January 2012 and December 2013were detected by PATHFAST system.Receiver operating characteristic (ROC) curve analysis was used to assess and compare the diagnostic value of presepsin and procalitonin (PCT).Logistic regression model was used to estimate the association between presepsin and sepsis.In addition,the correlations between presepsin and the clinical characteristics were analyzed in sepsis patients.Results Sepsis patients [1 266 (754-2 181) pg/ml] had higher presepsin level than SIRS[517 (349-939)pg/ml] and healthy individual controls [(182 ± 56)pg/ml] (Z value was 5.94 and 10.71,respectively,P value was ＜ 0.01 for all).The areas under curve (AUCs) of presepsin and PCT were 0.81 (95％ CI:0.74-0.89) and 0.78 (95％ CI:0.71-0.86),respectively,with no statistical significance (x2 =0.60,P =0.47).After adjusted for PCT,presepsin ＞ 1 060 pg/ml was independently associated with sepsis,with odds ratio (OR) of 7.80 (95 ％ CI:3.07-20.32).Severe sepsis patients [2 723 (2 002-4 234) pg/ml] had higher presepsin than sepsis patients[1 145 (656-1 436) pg/ml] (Z =4.00,P ＜0.01).The patients with inhosptal mortality [2 365 (1 256-3 567)pg/ml] had higher presepsin than survival ones[1 146 (660-1 452) pg/ml] (Z =2.99,P =0.003).Presepsin was positively correlated with PCT (r =0.75,P ＜ 0.01).The reference for presepsin was 72 to 292 pg/ml.Conclusions Presepsin was an useful biomarker for sepsisdiagnosis.The diagnostic value of presepsin and PCT was not completely overlap,and combinational using of these two biomarkers may improve the diagnostic accuracy of sepsis.In addition,presepsin had potential value for prognosis estimation.

Objective To explore the clinical effect of periarticular knee fractures combined with anterolateral ligament (ALL) avulsion fracture.Methods From June 2014 to November 2015,13 patients with ALL avulsion fracture in periarticular knee fractures were fixed by the star plate,cannulated or screws suture anchor,including 9 male and 3 female with the mean age of 39.5 years (range from 28 to 51 years).6 patients were diagnosed distal femoral fracture,4 tibial plateau fracture,and 3 tibial intercondylar eminence avulsion fracture which all combined with ALL avulsion fracture.Postoperatively,all patients were treated with the adjustable knee brace for 3 months.Results All patients were followed up for 4-20 months,the mean follow-up time was 13.5 months.The average surgical time was 130 min (range from 90 to 210 min).In all 13 patients,ALL was found and identified.Bone union was obtained in all patients,and the bone union time was 11.4 weeks (10-12 weeks).7 cases were fixed with star plate,5 cases were fixed with hollow screw,and 1 case was fixed with anchor.All follow-up patients underwent anteroposterior and lateral X-rays.Pain,swelling and functional recovery of the knee joint were observed.Patients were assessed postoperatively with International Knee Documentation Committee (IKDC) score,Lysholm score,and Tegner activity scale to evaluate the clinical effect.At the last follow-up,all patients had full range of motion of the knee joint which from 0° to approximate 120°.The Lysholm,objective IKDC were 86.5 and 84.6 respectively.Among the 13 patients evaluated,9 patients were graded A,and 4 patients were graded B by subjective IKDC.The Tegner activity scale at the last follow-up was 6.7.Incision of poor healing in 1 case,and got healed after 32 d cleaning dressing.Conclusion This study confirmed the presence of the ALL.The fixation of ALL avulsion fracture in periarticular knee fractures can be an effective procedure at a minimum follow-up of 13.5 months.

Objective To investigate the acute toxicity, subacute toxicity, nasal membrane local toxicity of the Magnolia biondii Pamp volatile oil nanometer bangosome. Methods Kunming mice and SD rats were selected as experimental material. Kunming mice were used in the acute and subacute toxicity tests by intragastric administration of Magnolia biondii Pamp volatile oil nanometer bangosome with different dosage and different time, and SD rats were used in the nasal membrane local toxicity test by nose dropping, while the control group was treated with intragastric administration of or nose dropping with normal saline for the same dosage. The treatment course lasted fifteen days. At the end of the tests, the general condition, routine blood test, function index of live and kidney, organ humid weight index, histological changes of liver and kidney and ultra microstructure change of rat nasal membrane were obtained and compared with the control group. Results In the acute toxicity test, the daily maximum tolerant dosage by intragastric administration was equal to 222.7 times of the clinical routine, with no marked toxic reaction. In the subacute toxicity test, the general condition, blood test, organ humid weight index and histological changes of live and kidney in different dosage groups were similar to the control group. While in the function index of live and kidney, uric acid was stepped down in the middle and large dose groups, and total bilirubin was decreased in the large dose group. The nasal membrane local toxicity test revealed that there was little change in the ultra microstructure of rat nasal membrane.Conclusion The Magnolia biondii Pamp volatile oil nanometer bangosome may have little toxicity by intragastric administration and nose dropping.

The oncogenic product of BCR-ABL is an abnormal tyrosine kinase that causes chronic myeloid leukemia (CML). With further research into the pathogenesis of CML, the discovery of compounds that selectively inhibit abnormal BCR-ABL tyrosine kinases is a research focus worthy of attention. The first three generations of BCR-ABL inhibitors are orthosteric inhibitors, which competitively block the binding of ABL protein tyrosine kinase to ATP and prevent it from activating downstream signals. The fourth-generation BCR-ABL inhibitors allosterically inhibit ABL protein tyrosine kinase by binding to the myristoyl pocket, providing greater selectivity and maintaining activity against drug-resistant mutations proteins. Novel drug design strategies such as proteolytic targeting chimera (PROTAC), covalent inhibitors and dual targeting inhibitors also provide new directions for the development of BCR-ABL kinase inhibitors. This paper reviews recent research advances on BCR-ABL kinase inhibitors and discusses drug design strategies for various novel BCR-ABL inhibitors.

Objective To establish a method of measuring adipose content and fat distribution of the thigh in normal glucose tolerance (NGT) subjects,and to investigate its relation to insulin resistance.Methods Insulin sensitivity was evaluated by hyperinsulinemic and euglycemic clamp technique,and femoral adipose content and fat distribution were determined by MRI in 30 individuals with NGT including 15 with normal weight and 15 overweighted or obese subjects.Results Compared to normal weight group,the subscutaneous adipose tissue of thigh (SCAT) [(176.7?21.6) cm~2 vs (115.0?12.8 ) cm~2,P＜0.05],adipose tissue of thigh beneath the fascia (SFAT) [(75.4?4.4 ) cm~2 vs (57.5?4.7 ) cm~2,P＜0.01] and intermuscular adipose tissue (IMAT) [(28.3?3.2) cm~2 vs (14.5?1.1 ) cm~2,P＜0.01] were greater in overweight/obesity group.Overweight/ obesity group had lower insulin sensitivity( glucose disposal rate under steady state of hyperinsulinemic euglycemic clamp:4.54?0.43 vs 7.88?0.75,P＜0.01).SFAT and IMAT were significantly correlated with insulin sensitivity.SFAT showed the most marked correlation with insulin sensitivity.Multiple stepwise regression analysis showed that the increased SFAT played a pivotal role in insulin resistance.Conclusion The adipose content and fat distribution are highly correlated with insulin sensitivity and the adipose tissue of thigh beneath fascia may play the most significant role in insulin sensitivity.
