OBJECTIVETo explore the effects of different fertilization methods on the outcomes of elective blastocyst culture.

METHODSWe retrospectively analyzed the outcomes of elective blastocyst culture for 1 153 cycles of IVF and 205 cycles of ICSI performed between january 2009 and December 2012.

RESULTSA total number of 14 748 embryos in the IVF group and 2 655 embryos in the ICSI group underwent sequential blastocyst culture, with 7 871 blastocysts formed in the former and 1 210 in the latter. No cycles were canceled for no blastocyst formation in either of the two groups. The rates of quality embryos, blastocyst formation and embryo utilization were significantly higher in the IVF than in the ICSI group (64.77 vs 58.72%, 53.37 vs 45.57%, and 60.06 vs 52.17%, all P < 0.05), but the rates of implantation, clinical pregnancy and abortion showed no significant differences between the two groups (48.94 vs 51.43%, 49.03 vs 52.02%, and 11.69% vs 15.56, all P > 0.05).

CONCLUSIONWith the same inclusion criteria of selective blastocyst culture, IVF has a lower risk of cycle cancellation due to no blastocyst formation and therefore may effect higher rates of blastocyst formation and embryo utilization than ICSI. Our study suggested that appropriate inclusion criteria of selective blastocyst culture should be laid down according to different fertilization methods.

OBJECTIVETo use distinctive water-medicine cup therapy for treatment of cervical spondylopathy of cervical type as a sample to provide a more effective cupping method for clinic.

METHODSOne hundred and forty cases were randomly divided into a medicine cup group (n = 47), a water cup group (n = 47) and a empty cup group (n = 46). The medicine cup group were treated by cupping therapy with a self-made medicine cup with 45 degrees C Chinese herb solution; the water cup group were treated with a cup with 45 degrees C water, and the empty cup group with a cup with nothing. Clinical symptoms and signs were observed for comparison of therapeutic effects.

RESULTSClinically cured was 39 cases, and markedly effective was 8 cases in the medicine cup group; 20 cases were clinically cured, 22 cases were markedly effective and 5 cases were effective in the water cup group; 12 cases were clinically cured, 19 cases were markedly effective and 15 cases were effective in the empty cup group. There were significant differences in the ratio of cases of different therapeutic effects and the difference of pain score before and after treatment between the medicine cup group and the water cup group (P < 0.05), between the water cup group and the empty cup group (P < 0.05), and between the medicine cup group and the empty cup group (P < 0.01).

CONCLUSIONThe therapeutic effect of the distinctive medicine cup is better than the water cup group, and the water cup group is better than the empty cup group.

OBJECTIVETo investigate the expression and function of miR-218 in gastric cancer.

METHODSmiR-218 levels were evaluated in 20 non-cardia gastric cancer tissues using TaqMan stem-loop real-time PCR analysis. Pre-miR-218 and anti-miR-218 inhibitor were used to change the miR-218 expression level and examine its effects on cell proliferation, apoptosis, cell cycle and cell invasion.

RESULTSComparing with the corresponding normal tissues, miR-218 expression was significantly reduced in the gastric cancer tissue (P < 0.01). Forced expression of miR-218 increased apoptosis in AGS cells. The proportion of apoptosis cells induced by transfection of pre-miR-218 was greater than that induced by control (21.6% vs. 10.4%, P = 0.032). Pre-miR-218 resulted in a significantly decreased cell growth activity (P < 0.01) and cell invasion (P < 0.05) of AGS cells compared with that of the control.

CONCLUSIONmiR-218 expression is reduced in gastric cancer. miR-218 may function as a tumor suppressor in gastric carcinoma.

BACKGROUNDIt has been widely demonstrated that endothelial progenitor cells are involved in several diseases and that they have therapeutic implications. In order to define the altered pulmonary vascular homeostasis in chronic obstructive pulmonary disease, we sought to observe the level and functions of circulating endothelial progenitor cells in patients with chronic obstructive pulmonary disease.

METHODSThe total study population included 20 patients with chronic obstructive pulmonary disease and 20 control subjects. The number of circulating endothelial progenitor cells (CD34(+)/CD133(+)/VEGFR-2(+) cells) was counted by flow cytometry. Circulating endothelial progenitor cells were also cultured in vitro and characterized by uptake of DiIacLDL, combining with UEA-I, and expression of von Willebrand factor and endothelial nitric oxide synthase. Adhesion, proliferation, production of nitric oxide, and expression of endothelial nitric oxide synthase and phosphorylated-endothelial nitric oxide synthase were detected to determine functions of circulating endothelial progenitor cells in patients with chronic obstructive pulmonary disease.

RESULTSThe number of circulating endothelial progenitor cells in the chronic obstructive pulmonary disease group was lower than in the control group: (0.54 ± 0.16)% vs. (1.15 ± 0.57)%, P < 0.05. About 80% of adherent peripheral blood mononuclear cells cultured in vitro were double labeled with Dil-acLDL and UEA-1. The 92% and 91% of them were positive for von Willebrand factor and endothelial nitric oxide synthase, respectively. Compared with the control, there were significantly fewer adhering endothelial progenitor cells in chronic obstructive pulmonary disease patients: 18.7 ± 4.8/field vs. 45.0 ± 5.9/field, P < 0.05. The proliferation assay showed that the proliferative capacity of circulating endothelial progenitor cells from chronic obstructive pulmonary disease patients was significantly impaired: 0.135 ± 0.038 vs. 0.224 ± 0.042, P < 0.05. Furthermore, nitric oxide synthase (112.06 ± 10.00 vs. 135.41 ± 5.38, P < 0.05), phosphorylated endothelial nitric oxide synthase protein expression (88.89 ± 4.98 vs. 117.98 ± 16.49, P < 0.05) and nitric oxide production ((25.11 ± 5.27) µmol/L vs. (37.72 ± 7.10) µmol/L, P < 0.05) were remarkably lower in endothelial cells from the chronic obstructive pulmonary disease group than the control.

CONCLUSIONCirculating endothelial progenitor cells were decreased and functionally impaired in patients with chronic obstructive pulmonary disease.

Objective:To evaluate the efficacy of Qinggan Bupi Jiangtang Decoction combined with western medicine in the treatment of adult type 2 diabetes mellitus (T2DM) with with liver hyperactivity and spleen deficiency syndrome.Methods:Prospective cohort study. A total of 103 T2DM patients with liver hyperactivity and spleen deficiency syndrome in the Department of endocrinology of Shanghai Municipal Hospital of Traditional Chinese Medicine from February 2020 to February 2021 were randomly divided into the observation group (52 cases) and the control group (51 cases) according to random number table method. Both groups were treated with conventional western medicine, the control group was treated with sitagliptin phosphate on the basis of routine treatment, and the observation group was treated with Qinggan Bupi Jiangtang Decoction on the basis of routine treatment. Both groups were treated for 12 weeks. TCM symptom scores were performed before and after treatment. The FPG, 2hPBG, HbA1c and fasting insulin (FINS) were detected by dry chemistry method and Roche electroluminescence method, and insulin resistance index (HOMA-IR) was calculated. The clinical efficacy was evaluated by dynamic blood glucose monitoring indexes TIR (percentage of time when glucose was in the range of 3.9-10.0 mmol/L), TAR (percentage of time when glucose was higher than the target range ≥ 11.1 mmol/L) and TBR (percentage of time when glucose was lower than the target range <3.9 mmol/L).Results:The total effective rate was 92.3% (48/52) in the observation group and 56.9% (29/51) in the control group ( χ2=15.32, P<0.01). The score of TCM syndrome in the observation group was significantly lower than that of the control group ( t=6.30, P<0.01). The compliance rate of HbA1c in the observation group was 46.2% (24/52) and that of the control group was 23.5% (12/51). There was significant difference between the two groups ( χ2=5.80, P=0.016). Compared with the groups before treatment, MAGE, TAR, TBR significantly decreased and TIR significantly increased in both groups after treatment ( P<0.01), but there was no significant difference between the two groups after treatment ( t values were 0.78, 1.06, 0.22 and 1.45, respectively, P>0.05). Compared with the groups before treatment, the levels of FPG, 2 hPBG and HbA1c in the two groups significantly decreased after treatment ( P<0.01), but there was no significant difference between the two groups after treatment ( t values were 1.32, 0.18,1.50, respectively, P>0.05). Compared with the groups before treatment, the levels of FINS and HOMA-IR in the two groups significantly decreased after treatment ( P<0.01), but there was no significant difference between the two groups after treatment ( t values were 1.25, 0.51, respectively, P>0.05). There were no adverse reactions in the observation group, 2 cases of mild nausea and 1 case of transient diarrhea in the control group. There was no significant difference between the two groups ( χ2=3.15, P=0.118). Conclusion:Qinggan Bupi Jiangtang Decoction combined with routine treatment can improve the blood glucose level, TIR and blood glucose standard rates of adult T2DM with liver hyperactivity and spleen deficiency syndrome, and the curative effect is equivalent to sitagliptin phosphate tablets.

Objective: To study the clinicopathological and genetic features of natural killer (NK)-cell enteropathy for better understanding of this rare disease and prevention of its misdiagnosis. Methods: Two cases of NK-cell enteropathy were diagnosed in the First Affiliated Hospital of Zhengzhou University, China from October 2017 to February 2021. The clinical characteristics, morphology, immunohistochemistry, Epstein-Barr virus-encoded RNA (EBER) in situ hybridization and T cell receptor gene rearrangement were analyzed. The patients were followed up by a telephone interview. Results: The patients were both male, aged 40 and 28 years, respectively. Both patients were admitted to the hospital for an annual checkup without obvious gastrointestinal symptoms. The endoscopy showed that the gastric body of case 1 had a mucosal bulge, small area of congestion and erosion, while the rectum of case 2 had congestion and erosion. Microscopically, the lesions of the 2 cases were relatively limited. Many lymphoid cells infiltrated within the lamina propria of the mucosa and into the muscularis mucosa in case 2. In case 1, the glands were reduced in the lesion, and the glandular cavity was slightly compressed and deformed. There was no infiltration or destruction of the glands in either case. Lymphoid cells were atypical, with medium-to-large cell sizes. Their cytoplasm was medium-to-slightly abundant and appeared eosinophilic or translucent. In case 2, characteristic eosinophilic granules were seen in the cytoplasm of a few cells. The nuclei in both cases were round, oval and irregular, with fine chromatin, inconspicuous nucleoli, and no mitotic figures were noted. Necrosis was seen in case 1 while both cases had no central growth or destruction of blood vessels. Immunophenotyping showed that CD56, granzyme B and TIA-1 were positive in both cases, part of the cells was CD3-positive, and some cells were weakly CD4-positive in case 2. The CD5, CD8, CD30, ALK and B-lineage markers (CD20, CD79α) were all negative. The Ki-67 proliferation index was about 60% and 30%, respectively. Both cases were EBER negative. TCR gene rearrangement was polyclonal. Follow-up showed that none of the 2 patients had any special treatments and stayed well. Conclusions: NK-cell enteropathy is rare, with biological behaviors similar to benign tumors, and occasional recurrence. Its histology and immunophenotype are easily confused with NK/T cell-derived lymphomas. Combination of its unique endoscopic features, EBER negativity, polyclonal TCR gene rearrangement and good prognosis can confirm the diagnosis and avoid misdiagnosis and overtreatment.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
