The difference between NSE in single and double eyes is worthy of further study.
ABSTRACT
Hepatocellular carcinoma (HCC) is one of the most common malignant tumors in clinical practice and has the features of high incidence rate, poor prognosis, and high mortality rate, and its incidence rate and mortality rate rank among the top malignant tumors in the world. High heterogeneity of HCC affects the evolution and therapeutic response of HCC. Since most HCC patients are in the advanced stage at the time of diagnosis, systemic treatment has become the main treatment option. In recent years, remarkable achievements have been made in molecular targeted therapy and immunotherapy for HCC, and the latest NCCN guidelines for the systemic treatment of HCC show that sorafenib, lenvatinib, and atezolizumab combined with bevacizumab are recommended as the first-line treatment of HCC, and regorafenib, cabozantinib, nivolumab, pembrolizumab, and ramucirumab are the second-line treatment options for HCC. In the era of precision medicine, how to select the optimal individualized systemic treatment regimen is the key problem in the systemic treatment of HCC. This article reviews the advances in the systemic treatment of HCC in the era of precision medicine and discusses the development direction of HCC treatment in the future.
ABSTRACT
OBJECTIVE@#To investigate the effects of Composition of Ophiopogon polysaccharide, Notoginseng total saponins and Rhizoma Coptidis alkaloids (CONR) on myocardial apoptosis of diabetic atherosclerosis (DA) rabbits METHODS: Sixty male New Zealand white rabbits were randomly divided into 6 groups [control group, model group, CONR high-dose group (450 mg/kg), CONR medium-dose group (150 mg/kg), CONR low-dose group (50 mg/kg), and simvastatin group] by using a completely random method, 10 in each group. DA model was established by intravenously injected alloxan combined with high-fat diet and abdominal aortic balloon injury. After mediation for 10 weeks, fasting blood glucose (FBG), glycosylated hemoglobin (GHB), glycosylated serum protein (GSP), fructoseamine (FRA), aldose reductase (AR), advanced glycation end products (AGEs) in serum were measured by enzyme linked immunosorbent assay (ELISA) method; the expression of receptor of AGEs (RAGE) in myocardial tissue were observed by immunohistochemical method; and p-Jun N-terminal kinase (p-JNK), caspase-3, B-cell lymphoma-2 (bcl-2) protein expression in myocardial tissue were measured by Western blotting. The myocardial apoptosis was detected by TdT-mediated dUTPnick-end labeling (TUNEL) method, and apoptosis index (AI) was calculated.@*RESULTS@#Compared with the control group, serum FBG, GHB, GSP, FRA, AR, AGEs and the expression of myocardium RAGE, p-JNK, caspase-3 proteins, as well as apoptosis index (AI) were significantly increased and bcl-2 protein was significantly decreased in the model group (P<0.01). Compared with the model group, the levels of serum FBG, GHB, GSP, FRA and AR showed a significant decline in CONR high- and medium-dose groups (P<0.01). FBG and GHB showed a significant decline in CONR low-dose group (P<0.01). Compared with the model group, the expression of serum AGEs and myocardium RAGE, p-JNK and caspase-3 protein as well as AI were significantly decreased and bcl-2 protein was significantly up-regulated in all treatment groups (P<0.01); high-dose CONR had the most significant effect on abovementioned indices compared with other treatment groups (P<0.01). Middle-dose CONR had better effect on serum AGEs compared with the low-dose group (P<0.01); middle-dose CONR and simvastatin groups had better effect on the expression of caspase-3, bcl-2 protein, myocardium apoptosis compared with the CONR low-dose group (P<0.01).@*CONCLUSION@#CONR may effectively inhibit myocardial apoptosis on DA rabbits by intervening AGEs-RAGE and JNK, caspase-3, and bcl-2 protein expressions.

ABSTRACT
OBJECTIVE: To explore changes of biochemical indicators in maintenance hemodialysis patients in the last year of their survival.METHODS: Maintenance hemodialysis patients died from January 1, 2008 to December 31, 2017 were screened for enrollment. They were divided into two groups according to the cause of death: CCVD group and non-CCVD group. For the enrolled patients, biochemical indexes were performed every 3 months within one year before the end of life. RESULTS: A total of 145 cases(80 males, 65 females, median age of death at age 71) were included. Patients were divided into two groups according to the causes of death: 74 cases died of cardio-cerebrovascular diseases(CCVD group) and 71 cases died of non-cardio-cerebrovascular diseases(non-CCVD group). Serum albumin and creatinine concentration were maintained at high levels in the CCVD group and serum phosphorus increased one month before death. The serum calcium compliance rate in the CCVD group was significantly lower than that in the non-CCVD group at 9 months and 6 months before death. The proportion of patients with serum calcium >2.5 mmol/L at 12 th-6 th month before death and with serum phosphorus >1.78 mmol/L at 6 th-1 st months before death was higher than that of non-CCVD group. Serum albumin and creatinine concentration remained lower level and the later decreased early and significantly in the non-CCVD group. The proportion of patients with serum phosphorus <1.13 mmol/L was higher than that of the CCVD group at 3 months and one month before death. Serum albumin in patients who died from infective diseases began to decline significantly at the time of 6 months before death and decreased by 8.57% during 6 months. Serum albumin was consistently lower than 38 g/L and 36 g/L in patients who died from cachexia syndrome and tumor respectively in the last year before death. CONCLUSION: Serum creatinine concentration, serum calcium, serum phosphorus,serum albumin and other indicators of MHD patients with different death causes within the last year of survival presented characteristic changes.

ABSTRACT
Objective To investigate the dosimetric characteristics between helical tomotherapy ( HT) and intensity-modulated radiotherapy ( IMRT) plans in children receiving craniospinal irradiation and estimate the risk of radiogenic second cancer according to the excess absolute risk ( EAR) model. Methods Computer-tomography scans of 15 children who received craniospinal irradiation between 2012 and 2017 were selected. HT and IMRT plans were designed for each patient after contouring the volumes of tumors and organ at risks ( OARs) and then the homogeneous index ( HI) , conformity index ( CI) , the maximum dose and the mean dose of OAR,V10 and V20 were analyzed to optimize the clinical treatment plan. The second cancer risk was estimated by DVH of each organ and EAR model and statistically compared between HT and IMRT. Results Both two plans met the clinical requirements in target coverage ( 100％ dose≥95％ target volume).The HI in the HT group was significantly superior to that in the IMRT group (P=0. 000) whereas no significant difference was noted in CI between two groups. Compared with the IMRT plan, HT plan possessed absolute advantage in protecting hippocampus and the D2％ and Dmean were significantly lower ( P=0. 000).As for the protection of OAR, the Dmax, Dmean and V20 of thyroid (P=0. 001,0. 002 and 0. 014) and Dmax,V10 of heart ( P=0. 001 and 0. 003) in the HT plan were significantly lower than those in the IMRT plan. In terms of second cancer risk, HT plan yielded a significantly higher second cancer risk for thyroid and lung compared with IMRT the EAR in thyroid was 28. 666 vs. 26. 926 ( P=0. 010 ) and 20. 496 vs. 18.922( P=0. 003) in lung. Both plans yielded a relatively high second cancer risk for stomach ( P=0. 248), whereas a low second cancer risk for liver (P=0. 020). Conclusions HT plan is superior to IMRT plan in the hippocampus-sparing craniospinal irradiation in children. However, HT plan yields a high second cancer risk for thyroid and lung. Consequently, the balance between the carcinogenic risk and the effect on other normal tissues should be assessed in the establishment of therapeutic plan.
ABSTRACT
Nosocomial infection (NI) is one of the most significant complications arising after open heart surgery,and leads to increased mortality,hospitalization time and health resource allocation.This study investigated the morbidity,mortality,and independent risk factors associated with NI following open heart surgery.We retrospectively surveyed the records of 1606 consecutive cardiovascular surgical patients to identify those that developed NI.The NI selection criteria were based on the Centers for Disease Control and Prevention (CDC) guidelines.The term NI encompasses surgical site infection (SSI),central venous catheter-related infection (CVCRI),urinary tract infection (UTI),respiratory tract infection and pneumonia (RTIP),as well as other types of infections.Of 1606 cardiovascular surgery patients,125 developed NI (7.8％,125/1606).The rates of NI following surgery for congenital malformation,valve replacement,and coronary artery bypass graft were 2.6％ (15/587),5.5％ (26/473) and 13.6％ (32/236),respectively.The NI rate following surgical repair of aortic aneurysm or dissection was 16.8％ (52/310).Increased risk of NI was detected for patients with a prior preoperative stay ≥3 days (OR=2.11,95％ CI=1.39-3.20),diabetes (OR=2.00,95％=CI 1.26-3.20),length of surgery ≥6 h (OR=2.26,95％ CI=1.47-3.47),or postoperative cerebrovascular accident (OR=4.08,95％ CI=1.79-9.29).Greater attention should be paid toward compliance with ventilator and catheter regulations in order to decrease NI morbidity and mortality following cardiovascular procedures.

ABSTRACT
Objective To investigate the serum 25-hydroxy vitamin D concentrations and related factors in early pregnancy. Methods Plasma was collected in the first trimester from 23 396 pregnant women to inves-tigate the vitamin D level, and its distribution and differences in different age, body maxx index ( BMI) and seasons between primipara and multipara. Preterm birth was used as an indicator of clinical outcomes. Vitamin D concentrations were measured using chemiluminescence microparticle immunoassay. Results 25-hydroxy vi-tamin D level was 42. 0 (17. 6-76. 6) nmol/L in totally 23 396 pregnant women with early pregnancy, and 5% and 95% percentile sites of vitamin D level were 20. 2 nmol/L and 70. 7 nmol/L respectively. There were 18 170 (77. 7%) primiparas and 5 226 (22. 3%) multiparas, with the mean age of 30. 0 (24. 0-38. 0) years and BMI of 20. 7 (16. 5-27. 6) kg/m2. The number of cases detected in spring (March, April and May), summer (June, July and August), autumn (September, October and November months) and winter (Decem-ber, January and February) were 5 878, 5 554, 5 974, and 5 990, respectively, and the vitamin D levels were 40. 0 (29. 3, 52. 7) nmol/L, 46. 2 (35. 6, 57. 2) nmol/L, 43. 8 (33. 1, 54. 8) nmol/L and 37. 2 (26. 9, 49. 9) nmol/L respectively, with the difference in vitamin D levels statistically significant among the four seasons (P<0. 001). According to BMI, all pregnant women were divided into four groups as BMI<18. 5 kg/m2, 18. 5 kg/m2≤BMI≤23. 9 kg/m2, 24 kg/m2≤BMI≤27. 9 kg/m2, BMI≥28 kg/m2, and the levels of 25-hydroxy vitamin D were 43. 5 (30. 9, 56. 9) nmol/L, 42. 1 (30. 8, 53. 8) nmol/L, 39. 9 (30. 7, 50. 4) nmol/L and 39. 7 (30. 7, 49. 4) nmol/L respectively with the difference statistically significant among the four groups. The levels of vitamin D detected in pregnant women with age<25 years, 25~29 years, 30~34 years,≥35 years were 39. 1 ( 28. 4, 52. 3) nmol/L, 41. 3 ( 30. 1, 52. 9) nmol/L, 42. 4 ( 31. 2, 54. 1) nmol/L and 43. 8 (31. 9, 55. 7) nmol/L respectively and the difference was statistically significant (P<0. 001). The levels of 25-hydroxy vitamin D in primary and multiparas were 41. 6 (30. 2, 52. 9) nmol/L and 43. 5 (32. 5, 56. 8) nmol/L with the difference statistically significant (P<0. 001). Among women of different gestational age during childbirth, the differences in serum 25-hydroxy vitamin D in early pregnancy were not statistically significant (P=0. 121). The severe deficiency of vitamin D in early pregnancy was defined as serum level of 25-hydroxy vita-min D less than 5th level. There were statistical differences in the probability of severe vitamin D deficiency of dif-ferent ages, seasons and BMI between primiparas and multiparas. Conclusions Pregnant women of lower weight, lower age and primiparity have higher incidence of the severe vitamin D deficiency in early trimester of pregnancy. There is significant difference in 25-hydroxy vitamin D level among the different seasons (winter<spring<autumn<summer). Vitamin D level in early pregnancy is not associated with preterm birth.
ABSTRACT
Aim To study the growth inhibitory effect of the conjugate ( ovarian cancer specific targeting peptide and cisplatin, OSTP-DDP ) that targeting ovarian cancer cells A2780. Methods Using chemical method to syn-thesize OSTP-DDP, ovarian cancer cells A2780 were cul-tured in vitro, using CCK-8 method ( Cell Counting Kit-8) to detect the growth inhibitory effect of ovarian cancer A2780 cells, which were disposed by OSTP-DDP and DDP. Annexin V-FITC was used to detect the cycle and apoptosis effect of ovarian cancer A2780 cells which were disposed by OSTP-DDP and DDP. Results According to the mass spectrometry and the high performance liquid chromatography ( HPLC ) analysis, OSTP-DDP was proved to synthesize successfully. CCK-8 assay showed that both OSTP-DDP and DDP could play the growth in-hibitory effect and showed a concentration-dependent manner when cells were treated in different concentrations (10,20,40,80,160,320μmol·L-1 ) respectively after 24 h, 48 h, 72 h. And the effect of OSTP-DDP was stronger than DDP (P<0. 05), indicated OSTP-DDP had targeted cytostatic effect. The result of the flow cytometry showed that cell cycle was mostly arrested in G1 phase after 72h treated by OSTP-DDP and DDP, the inhibitory effect of OSTP-DDP was stronger than DDP (P<0. 05). The apop-tosis effect of OSTP-DDP was stronger than DDP ( P <0. 01),suggested that OSTP-DDP had a stronger targeting apoptosis-inducing effect. Conclusion OSTP-DDP has the targeting growth inhibitory effect on the ovarian cancer cell A2780, OSTP as a chemotherapeutic drug targeting vector has a great prospect to treat ovarian cancer.
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate clinical effect and safety of floating needle therapy and duloxetine in treating patients with persistent somatoform pain disorder (PSPD).</p><p><b>METHODS</b>Totally 108 PSPD patients were randomly assigned to the floating needle treatment group, the duloxetine treatment group, and the placebo treatment group, 36 in each group. Patients in the floating needle treatment group received floating needle therapy and placebo. Those in the duloxetine treatment group received duloxetine and simulated floating needle therapy. Those in the placebo treatment group received the placebo and simulated floating needle therapy. All treatment lasted for six weeks. Efficacy and adverse reactions were evaluated using Simple McGill pain scale (SF-MPQ) and Treatment Emergent Symptom Scale (TESS) before treatment and immediately after treatment, as well as at the end of 1st, 2nd, 4th, and 6th week of treatment, respectively. Hamilton Depression Scale (HAMD, 17 items), Hamilton Anxiety Scale (HAMA) were assessed before treatment and at the end of 1st, 2nd, 4th, and 6th week of treatment, respectively. Patients in the floating needle treatment group and the duloxetine treatment group with the total reducing score rate of SF-MPQ in Pain Rating index (PRI) ≥ 50% after 6 weeks' treatment were involved in the follow-up study.</p><p><b>RESULTS</b>(1) Compared with the same group before treatment, SF-MPQ score, HAMD score and HAMA total scores all decreased in all the three groups at the end of 1st, 2nd, 4th, and 6th week of treatment (P < 0.05, P < 0.01). Besides , each item of SF-MPQ significantly decreased immediately after treatment in the floating needle treatment group (P < 0.01). Compared with the placebo treatment group, SF-MPQ, HAMD, and HAMA total score in the floating needle treatment group significantly decreased after 1, 2, 4, and 6 weeks of treatment (P < 0.05, P < 0.01). SF-MPQ score, HAMD score and HAMA total score in the duloxetine treatment group also significantly decreased after 2, 4, and 6 weeks of treatment (P < 0.05, P < 0.01). (2) There were 3 patients (8.3%) who had adverse reactions in the floating needle treatment group, 17 (50.0%) in the duloxetine treatment group, and 7 (21.2%) in the placebo treatment group. Compared with the placebo treatment group, the incidence of adverse reaction increased in the duloxetine treatment group (χ² = 6.04, P < 0.05). Besides, it was higher in the duloxetine treatment group than in the floating needle treatment group (χ² = 14.9, P < 0.05). (3) There were 19 patients in the floating needle treatment group and 17 patients in the duloxetine treatment group involved in the follow-up study. Compared with 6 weeks after treatment, no significant difference was observed at 3 and 6 months after treatment in the score of SF-MPQ, HAMD, and HAMA in the floating needle treatment group and the duloxetine treatment group. No significant difference was observed between the two groups (P > 0.05). There were 5 patients (29.4%) who had adverse reactions in the duloxetine treatment group, and no adverse reactions were observed in the floating needle treatment group. The adverse reaction rate was significantly different between the two groups (χ² = 4.26, P < 0.05).</p><p><b>CONCLUSIONS</b>Floating needle therapy and duloxetine were effective in treatment of patients with PSPD. However, floating needle therapy could relieve pain more rapidly than duloxetine, with obviously less adverse reactions.</p>

Mast cells and monocyte-macrophage cells share similar phenotypic characteristics.In recent years, it has been found that mast cell plays a role in the many pathophysiological processes such as the chronic inflammation, angiogenesis, and tissue remodeling and progressive fibrosis.More and more evidences showed that mast cells played a catalytic role in the renal chronic inflam-mation and progressive fibrosis and were related to the development and prognosis in patients with chronic kidney disease( CKD) .This paper will review the pathogenesis of renal injury induced by mast cells, especially in promoting the renal fibrosis in order to provide some new ideas for treatment and prognosis evaluation of CKD patients.
ABSTRACT
Objective To explore the effect of in utero exposure to inlfammation on innate immune response in preterm infants. Methods Forty-seven premature infants with gestational age<35 weeks were recruited in this study. According to his-tological evidence of placental infection, all neonates were divided into intrauterine inlfammation positive group and negative group. Mononuclear cells and monocytes were isolated from umbilical cord blood, and were cultured in vitro in the presence or absence of LPS (100 ng/ml). The levels of interleukin 1β(IL-1β), interleukin 6 (IL-6), tumor necrosis factor alpha (TNF-α) and interleukin 10 (IL-10) in cord blood plasma and monocyte cultural supernatants were measured by ELISA respectively. The level of IL-1β, TNF-α, IL-6 and IL-10 mRNA were detected by Real-time PCR. Expression of HLA-DR on surface of CD14+monocytes and ratio of CD3+CD4+/CD3+CD8+T was analyzed by lfow cytometry. Results (1) The level of cord plasma IL-6 in intrauterine inlfammation positive group was signiifcantly higher than in negative group. (P=0.02). (2) After stimulation of LPS, levels of IL-1β, IL-6, TNF-α, IL-10 in supernatants were increased signiifcantly, in consistence with their mRNA expression (P<0.05) in both groups. (3) Expression of HLA-DR on surface of monocytes was signiifcantly decreased after stimulation with LPS in intrauterine inlfammation positive group (P=0.012), but was signiifcantly increased in negative group (P=0.0305). Con-clusions In utero exposure to inlfammation does not suppress the response of monocytes to LPS in preterm neonates, but impairs the antigen presenting function in monocytes.
ABSTRACT
Objective: To study the blood components in Zhizi Dahuang Decoction (ZDD) and to further explore its pharmacodynamic material basis. Methods: UFLC fingerprints of serum in rats after ZDD treatment were established with serum pharmacochemistry method. The UFLC profiles of serum samples collected after the treatment of ZDD, ZDD without one of the component herbs and single crude herb were compared, and the transitional constituents to blood and their metabolites were analyzed. Results: Twenty-one constituents absorbed into rat blood were detected after oral administration of ZDD, 12 of which were metabolites. Other nine were prototype constituents, three of which were recognized as geniposide, aloeemodin, and rhein by comparing with reference substances, respectively. Conclusion: The constituents of ZDD absorbed into blood are preliminarily identified, which could lay the foundation for the illumination of its pharmacodynamic material basis.
ABSTRACT
[Abstract ] Objective Chronic renal disease,a common and frequent disease,is the most cause inducing chronic renal failure. There is an important guiding significance for renal biopsy in the diagnosis,treatment and prognosis of renal disease.The aim of this study was to analyze the characteristics of renal biopsy and the relation between pathological types and clinical presentation in Tibet. Methods Between June 2011 and December 2013 in General Hospital of Tibetan Military Command, Lhasa, percutaneous renal biopsy were per-formed in 107 renal patients.In this study, the gender, age, pathologic entities, and clinical manifestation were analyzed retrospectively. The final diagnosis was made by the clinical manifestation, laboratory examination,and pathologic results. Results The mean age at renal biopsy was 29.8 ±12.2(10~66)years in 47 male cases (43.9%) and 69 female cases (56.1%).This includes 75 Tibetan cases (70.1%), 31 Han cases (28.9%), and Bai cases (1.0%).The primary glomerular disease was 95.3%and the secondary glomerular disease was 4.7%in the total 107 cases.Fourty-four point three percent of the primary glomerular disease were male cases and 100%of secondary glomerular disease were female cases.The main pathological type of the primary glomerular disease was podocyte nephropathy (43.9%), followed by membranous nephropathy (18.7%), IgA nephropathy (11.2%), focal segmental glomerulosclerosis (9.3%) and mesangiocapillary glomerulonephritis (5.6%).The clinical manifestations of 107 cases were classified as syndrome of nephrotic syn-dromn(69.1%),urinary abnormalities(14.9%),isolated macrographic haematuria (3.7%),chronic renal failure(2.8%).Among the nephrotic syndrome,podocyte disease was 63.5%,membranous glomerulopathy was 18.9%,focal segmental glomeruolsclerosis was 8.1%,and membranoproliferative glomerulonephritis was 5.4%. Conclusion The primary glomerulonephritis was the most common glomerular diseases at high altitude area in Tibet.The most frequent type of pri-mary glomerular nephritis was podocyte disease, and the most frequent type of secondary glomerular nephritis was Henoch-Schonlein purpura glomerulonephritis.
ABSTRACT
Purpose To investigate the correlation between promoter methylation of RKIP and the clinicopathological features of gastric carcinoma and to analyze the correlation between promoter methylation of RKIP and expression of RKIP. Methods The protein ex-pression and promoter methylation of RKIP were detected in 45 cases of surgically resected gastric carcinoma specimens and 21 cases of corresponding normal tissues using the immunohistchemistry SP method and methylation-specific PCR ( MSP) . Results The positive rate of promoter methylation of RKIP was 48. 89% in gastric carcinoma tissues and 4. 8% in adjacent tissues (P<0. 05). The positive rate of the expression of RKIP protein was 42. 22% in gastric carcinoma tissues and 90. 48% in adjacent tissues (P<0. 05). The pro-tein expression and promoter methylation of RKIP were correlated with the degree of differentiation and lymph node metastasis ( P<0. 05) . Expression of RKIP protein in gastric carcinoma was associated with promoter methylation of RKIP. Conclusions Promoter abnormal methylation of RKIP may be one reason of the deletion of expression of RKIP protein, which correlates with occurrence and development of gastric carcinoma.
ABSTRACT
To investigate the time-course changes of myogenic tone in mesenteric small artery (MSA) of spontaneously hypertensive rat (SHR), thirty-two 7-week aged SHR rats were randomly divided into four groups (8, 16, 24, 32 weeks of age), and 32 sex- and age-matched Wistar-Kyoto (WKY) rats were assigned to control groups (CON). On the day of the study, segments of MSA were isolated and then cannulated to the two pipettes. Vascular diameters in response to the increased intraluminal pressure (from 0 mmHg to 150 mmHg, by 25 mmHg steps) of isolated MSA under no-flow conditions were recorded by a Pressure Myograph System both in physiologic salt solution (PSS) (active diameter, Da) and calcium-free PSS (passive diameter, Dp). The myogenic tone was calculated by (Dp - Da)/Dp × 100%. The tail artery pressure and vascular myogenic tone in SHR rats were significantly higher than those of the CON rats. Before 24 weeks, the vascular myogenic tone of MSA in SHR group increased monotonically, but at the end of 32 weeks, the vascular myogenic tone decreased in comparison with that in 24-week group, but was significantly higher than that in CON group. The tail artery pressure in SHR group slowly increased monotonically with increasing weeks of age, and the tail arterial pressure in 32-week group remained significantly higher than that in 24-week group. Vascular myogenic tone may participate in the whole process of hypertension. Early in the development of hypertension, because of the compensatory role of vascular tone, the vascular function has been partially compensated, thus guaranteeing adequate blood supply to organs. Late in the development of hypertension, because of the decompensation of myogenic tone, the vascular function is damaged, leading to the occurrence of severe vascular disease.
