Objective To investigate the clinical effect of perioperative electroacupuncture intervention on postoperative delirium (POD) in hip replacement surgery patients.Method One hundred and twenty-eight patients who would undergo hip replacement surgery were randomly allocated to treatment and control groups, 64 cases each. The treatment group received perioperative electroacupuncture and the control group, routine preoperative preparation and postoperative treatment. Serum S100β protein concentration was measured in the two groups of patients at one day before, the end of and one day after surgery. The incidences of POD were compared between the two groups at one, two and three days after surgery.Result There was a statistically significant difference in the incidence of POD between at one day after surgery and recovery from anesthesia in the two groups (P<0.01). In the treatment group, the incidence of POD was significantly lower at two and three days than at one day after surgery (bothP<0.05) and at three days than at two days after surgery (bothP<0.05). There was a statistically significant difference in the incidence of POD between the treatment and control groups at different time points (recovery from anesthesia, and one, two and three days after surgery) (P<0.01). In the treatment group, there was a statistically significant difference in S100β protein concentration between at one day after and the end of surgery (P<0.05). There was a statistically significant difference in S100β protein concentration between the treatment and control groups at the end of and one day after surgery (P<0.05).Conclusions Perioperative electroacupuncture treatment can effectively decrease postoperative incidence of delirium and its duration in hip replacement surgery patients.

Objective To explore the role of TGF-βand TGIF in the pathogenesis of endometriosis. Methods The expression of TGF-β and TGIF was detected by immunohistochemistry method in the ectopic and eutopic endometrium of 30 cases with endometriosis (ec-topic endometrium group and eutopic endometrium group) and in the normal endometrium of 40 cases without endometriosis (control group). Result The expression of TGF -β in ectopic endometrium group was significantly higher than that in eutopic endometrium group and control group (P < 0.05). There was no significant difference in the expression of TGF- βbetween eutopic endometrium group and control group(P > 0.05). The expression of TGIF in ectopic endometrium group was significantly lower than that in eutopic endometrium group and control group( P <0.05). There was no significant difference in the expression of TGIF between eutopic endometrium group and control group(P > 0.05). There were negative correlation between the expressions of TGF - β and TGIF in ectopic endometrium group and eutopic endome-trium group(rs= - 0.769, - 0.549, P < 0.05). Conclusion The abnormal expression of TGF-β and TGIF in ectopic endometrium of pa-tients with endometriosis may be associated with the genesis and progression of endometriosis.

Objective:To explore the effect of heparanase (HPSE) on the cell adhesion and invasion ability of hepatoma carcino-ma (HC) cell. Methods:HPSE expressions in human HC cell lines (BEL-7402, HepG2, and HCCLM3) were measured by real-time re-verse transcriptase-polymerase chain reaction (RT-PCR) and Western blot analysis. Four recombinant miRNA vectors, pcD-NATM6.2-GW/EmGFP-miR-HPSE (pcDNA-miR-HPSE), were constructed and transfected into HCCLM3 cells. Full-length cDNA of HPSE gene was cloned into pIRES2-EGFP vector and transfected into HepG2 cells. Transfection efficiency was observed with fluores-cence microscope. HPSE expressions in transfected cells were measured by real-time RT-PCR and Western blot analysis. Adher-ence ability was determined with microplate reader, and invasion and migration abilities were detected with Transwell chambers. Re-sults:Both HPSE mRNA and protein relative expression levels were higher in the three types of HC cells than those in normal hepato-cyte (P<0.05). HPSE had the highest expression level in HCCLM3 cells and the lowest expression level in HepG2 cells (P<0.05). All five recombinant vectors met the experimental requirements. The transfection efficiencies were 75%-85%. The four miRNA vectors, pcDNA-miR-HPSE, significantly decreased HPSE expression in transfected HCCLM3 cells (P<0.05), and pcDNA-miR-HPSE-1 showed the best interference effect (P<0.05). Plasmid pIRES2-EGFP-HPSE increased HPSE expression in transfected HepG2 cells (P<0.05). After pcDNA-miR-HPSE-1 was transfected, the HCCLM3 cell adherence rate and the cell invasion and migration numbers dropped by almost 50%(P<0.01). After transfection of pIRES2-EGFP-HPSE, the HepG2 cell adherence rate and the cell invasion and migration numbers increased by nearly 40%(P<0.05). Conclusion:Different HPSE vectors could regulate bi-directionally the adher-ence, invasion, and migration abilities of transfected HC cells. HPSE may be related with adherence aside from invasion of HC cell.

Objective To assess the local treatment efficacy of percutaneous radiofrequency ablation(PRFA) in combination with percutaneous ethanol injection(PEI) therapy protocol for liver metastases in patients with colorectal cancer.Methods From February 2000 to February 2004, total of 61 liver metastatic lesions(1.5～7.8 cm) from 37 colorectal cancer patients were ablated by using RF-2000 generator and 10-needle LeVeen electrode percutaneously guided by B-ultrasound.Tumors larger than 2.5 cm in diameter were treated by multiple overlapping radiofrequency ablations encompassing the entire lesion as well as a rim of normal liver tissue(approximately 1.0 cm).PEI was performed additionally.The Chiba needle and Quadra-Fuse multi-pronged injection needle were used for tumors ranged 1～2 cm and for those larger than 3 cm respectively.Results The procedures were performed successfully in all patients.The post-PRFA/PEI complication rate was 5.4%.The follow-up rate was 97.3%(36/37).Thirteen patients achieved a complete response(CR),and 21 achieved a partial response(PR).The effective rate(CR+PR) was 94.4%.The patients' survival rates were 97.2% at 1 year,75.0% at 2 years,and 52.8% at 3 years respectively.Conclusion The results of this study suggest that the treatment protocol of PRFA in combination with PEI was an effective mini-invasive local ablation therapy,which was part of the comprehensive management of the colorectal liver metastases.

OBJECTIVETo observe the impacts on pain matrix (PM) brain area in the patients of cervical spondylosis of neck type treated with acupuncture at single point and the multiple points.

METHODSForty-nine patients of cervical spondylosis of neck type were randomized into a single-point group (25 cases) and a multiple-point group (24 cases), and treated with acupuncture at Bailao (EX-HN 15) singly or Bailao (EX-HN 15) and Hegu (LI 4) in combination correspondingly. At the same time, 19 healthy people were selected as a control group. The resting state functional magnetic resonance imaging (fMRI) was conducted in each group before and after treatment. The changes in the regional homogeneity (ReHo) of brain area PM were analyzed in terms of the different therapeutic programs. The relevant analysis was on the scores of the Northwick Park neck pain questionnaire (NPQ) and short form 36 questionnaire (SF-36) for life quality.

RESULTSCompared with the control group, ReHo value was increased in supplementary motor area (SMA) of PM in the patients, of cervical spondylosis of neck type. In the single-point group, after treatment, ReHo value was reduced in the bilateral medial superior frontal gyri of patients. In the multiple-point group, ReHo values were reduced in the left medial superior frontal gyrus and right SMA in PM area after treatment. In the single-point group, ReHo value in each brain area of PM was not significantly correlated with NPQ and SF-36 scores. In the multiple-point group, the changes of ReHo value in superior frontal gyrus were positively correlated with those of NPQ scores.

CONCLUSIONConsidering the clinical efficacy of acupunctrue for cervical spondylosis of neck type, the overall result in the multiple-point group is better than that in the single-point group. It is deduced that the advantages of the therapeutic program in the multiple-point group is relevant with the cooperative integration of the stimulation at multiple points in cerebral analgesic center.

The CRISPR-Cas (clustered regularly interspaced short palindromic repeats and CRISPR-associated) system is an "adaptive immune system" found in the genomes of bacteria and archaea which is mediated by RNA and resists foreign nucleic acid invasion.Take advantage of specific recognition of target nucleic acid, CRISPR-Cas system can efficiently edit their target site or accurately regulate gene expression, and now have been developed into a powerful tool for gene editing.According to the different compositions of the effector complex, the system has been divided into two categories: class 1 (type I, type IV, and type III) and class 2 (type II, type V, and type VI).Class 2 system, like the CRISPR-Cas9, is widely used in basic research due to the earliest discovery and best research.However, class 1 has not been maturely developed and utilized though it makes up 90% of the entire CRISPR-Cas system.In this essay, the classification of subtype, the assembly of Cascade complex, the cleavage and degradation mechanism of Cas3, and the application in gene editing of class 1 type I CRISPR-Cas system will be discussed and summarized to provide new ideas and methods for further mechanism studying and application of this category.

Objective:To explore the effects of self-made Huoxue Xiaozhong Xunxi Decoction combined with functional exercise on postoperative swelling of affected limbs, bone metabolism and recovery of knee function in patients with traumatic fracture of tibial plateau (FTP).Methods:Randomized controlled trial. totally 80 patients after FTP surgery in the Qidong Hospital of Traditional Chinese Medicine were enrolled and divided into two groups by random number table method from January 2018 to January 2022, with 40 cases in each group. After surgery, control group was treated with functional exercise, while observation group was additionally treated with self-made Huoxue Xiaozhong Xunxi Decoction. All were treated continuously for 8 weeks. The perioperative indexes (operation time, incision length, intraoperative blood loss, postoperative drainage volume, leaving bed time) in the two groups were recorded. The postoperative swelling and pain of affected limbs were observed, and detumescence time, pain relief time, fracture healing time and complete weight-bearing time were recorded. The knee function was evaluated by Hospital for Special Surgery (HSS). The level of serum bone morphogenetic protein-2 (BMP-2) was detected by ELISA, and total n-terminal propeptide of typeⅠprecollagen (t-PINP) and β-crossLaps (β-CTX) were detected by full-automatic immunoluminescence analyzer. The occurrence of postoperative complications in the two groups was recorded.Results:There was no significant difference in operation time, incision length, intraoperative blood loss, postoperative drainage volume or leaving bed time between the two groups ( P>0.05). The total effective rate of the observation group was 97.5% (39/40), while the control group was 80.0% (32/40), with statistical significance ( χ2=6.14, P=0.013). The detumescence time, pain relief time, fracture healing time and complete weight-bearing time were earlier in the observation group than control group ( P<0.01). After 10 d of treatment, VAS score and swelling degree in observation group were lower than those in the control group ( t=7.05, 3.81, P<0.01). After 8 weeks of treatment, levels of serum BMP-2 [(625.16±67.43) μg/L vs. (542.35±53.27) μg/L, t=6.10], t-PINP [(54.16±7.29) μg/L vs. (50.34±6.12) μg/L, t=2.54] and β-CTX [(1.26±0.38) μg/L vs. (1.04±0.23) μg/L, t=3.13] in observation group were higher than those in the control group ( P<0.05). During treatment, the incidence of complications in the observation group was 2.5% (1/40) and the control group was 7.5% (3/40), without statistical significance ( χ2=1.05, P=0.305). Conclusion:Self-made Huoxue Xiaozhong Xunxi Decoction combined with functional exercise is beneficial to improve pain and swelling of affected limbs and bone metabolism, and promote the recovery of knee function in patients after FTP surgery.

Placenta-mediated pregnancy complication (PMPC), including preeclampsia, fetal growth restriction and recurrent pregnancy loss, is caused by inadequate trophoblast invasion and abnormal remodeling of maternal spiral arteries in early pregnancy, resulting in adverse perinatal outcomes and affecting the long-term maternal and child health. However, the molecular mechanisms of PMPC remain unclear. Endocrine gland-derived vascular endothelial growth factor (EG-VEGF) is highly expressed in human placenta and plays an important role in the development of a normal placenta through promoting placental angiogenesis and inhibiting trophoblast migration and invasion. EG-VEGF dysregulation is closely related to the pathogenesis of PMPC. This review described recent advances in EG-VEGF for better understanding of the underlying mechanism of PMPC and providing a potential biomarker for early diagnosis of PMPC.
