BACKGROUND: The rehabilitative intervention accelerates the recombination and reconstruction of cerebral structure and function and then promotes the amelioration of function.OBJECTIVE: To evaluate the influence of early and late rehabilitative interventions on the motor function and activities of daily living (ADL) with neurologic deficit score (NDS), Fugl-Meyer assessment (FMA) and modified Barthel index in patients with cerebral infarction.DESIGN: A randomized controlled trial.SETTING: Department of Neurology, Qilu Hospital of Shandong University; Department of Rehabilitation, Jinan Great Wall Hospital; Department of Neurology, the Third People' s Hospital of Heze.PARTICIPANTS: Totally 216 inpatients with cerebral infarction (125 males and 91 females, aged 60-75 years), who were selected from Qilu Hospital of Shandong University, Jinan Great Wall Hospital and the Third People's Hospital of Heze from December 2000 to December 2003, were randomly divided into early rehabilitation group (n=108) and late rehabilitation group (n=108) after admission.INTERVENTIONS: In the early rehabilitation group, the patients began to receive rehabilitation at 48 hours to 14 days after the stability of vital signs and absence of the progress of neurological signs. In the late rehabilitation group, the patients began to receive rehabilitation at 15-30 days after attack. They were trained with Bobath method and motor relearning program, once a day, 45 minutes for each time, and 6 times every week.Before and 30 days after the rehabilitative treatment, the rehabilitation was evaluated with modified Barthel index (100 points as normal, 0-20 as extremely severe functional defect, 25-45 as severe functional defect, 50 -70 as moderate functional defect, 75-95 as mild functional defect), FMA (total score was 100 points, including the highest scores of upper and lower limb movement were 66 and 34 points respectively) and NDS (the highest and lowest scores were 45 and 0 point, 0-15 as mild, 16-30 as moderate, 31-45as severe).ter treatment.RESULTS: All the 216 patients with cerebral infarction were involved in obviously lower than that before treatment in both groups (P ＜ 0.01), lower in the early rehabilitation group than in the late rehabilitation group score at 30 days after treatment was obviously higher than that before treat ment in both groups (P ＜ 0.01), higher in the early rehabilitation group than in the late rehabilitation group [upper limb: (32.43±21.52), (26.69±19.79)dex: The modified Barthel index at 30 days after treatment was obviously higher than that before treatment in both groups (P ＜ 0.01), higher in the early rehabilitation group than in the late rehabilitation group [(54.23±30.33),(46.57±29.85) points, P ＜ 0.05].CONCLUSION: Both early and late rehabilitative interventions can obviously accelerate the recovery of neurological function, motor function and ADL, but the effect of early rehabilitative intervention is superior to that of the late one.

Objective To investigate the regulative effect of cyclooxygenase-2 (COX-2) 3'-UTR in HT29 colon cancer cells. Methods Total RNA was extracted from HT29 colon cancer cells and used as a template to amplify COX-2 gene by reverse transcription polymerase chain reaction. Using PCR technique to construct a series of luciferase reporter gene expression vectors containing various regions of the 3'-UTR of COX-2 (including the whole gene region, gene region between 1 to 156 bp, gene region between 1 to 347 bp, gene region between 1 to 1006 bp, gene region between 156 to 347 bp and gene region between 157 to 2217 bp). These reporter gene expression vectors and pRL-SV40 were co-transfected in HT29 colon cancer cells by Lipofectamine 2000. The relative luciferase activity of the HT29 colon cancer cells was tested. All data were analyzed via t test. Results The luciferase activity was reduced by 70.4%, 37.4%, 64.8% and 24.2% in HT29 colon cancer cells transfected with the whole COX-2 gene region, gene region between 1 to 156 bp, gene region between 1 to 347 bp and gene region between 156 to 347 bp, respectively (t = 6.13, 7.73, 9.75, 3.92, P < 0.05). No obvious changes of luciferase activity were observed in HT29 colon cancer cells transfected with gene regions between 1 to 1006 bp and between 157 to 2217 bp (t = 0.13, 0.01, P > 0.05). Conclusions A region between 156-347 bp in the 3'-UTR of COX-2 has been found which can down-regulate the expression of COX-2 with the cooperation of the ARE element. The 3'-UTR of COX-2 contains several control elements that regulate the expression of COX-2 in colon cancer cells.

Objective:To observe the therapeutic effects of acupuncture plus cupping therapy and Western medication alone for cervical radiculopathy. Methods: A total of 139 patients with cervical radiculopathy were randomly divided based on the random digital table into an acupuncture-cupping group (70 cases) and a Western medication group (69 cases). In the acupuncture-cupping group, Fengchi (GB 20) (bilateral), Dazhui (GV 14), Jianjing (GB 21) (bilateral) and Jiaji (EX-B 2) points of the neck [bilateral, midpoint between Fengchi (GB 20) and Dazhui (GV 14)] were punctured. After the arrival of the needling sensation, bilateral Fengchi (GB 20) and Jianjing (GB 21) were linked with electric stimulation and the rest acupoints were manipulated with the moderate needling technique. In the retaining of the needles, TDP lamp radiation was used. After acupuncture, the cupping therapy was applied to the local area. The treatment was given once every other day, 20 d for a course. After one course, the therapeutic effects were observed. The Western medication group was treated by oral administration of Meloxicam (Mobic), 7.5 mg, once a day, with water and liquid after meal. The therapeutic effects were observed after 20 d. Results:The total effective rate was 92.8% in the acupuncture-cupping group and 73.9% in the Western medication group, with a statistical difference between the two groups (P<0.05). After treatment, the scores of the clinical symptoms of the two groups were obviously declined (P<0.01), and the score of the clinical symptoms of the acupuncture-cupping group was better than that of the Western medication group, with a statistical difference (P<0.05). Conclusion:Acupuncture plus cupping therapy was more effective than administration of Meloxicam tablets alone in the treatment of cervical radiculopathy.

Objective To evalute and compare the efficacy and safety of epinephrine-saline submu-cosal injection of different concentrations on endoscopic submucosal dissection (ESD),and to discuss the best concentration of submucosal injection.Methods A total of 128 patients who underwent ESD were ran-domly assigned to submucosal normal saline injection group (group A,n =32),0.001% epinephrine-saline injection group (group B,n =32),0.002% epinephrine-saline injection group (group C,n =32),and 0.004% epinephrine-saline injection group (group D,n =32).The incidence of bleeding during and after ESD were counted,the blood preasure and heart rate of preoperative and intraoperative,the amount of sub-mucosal injection,the time of operation were observed.Results ESD was successfully performed on all pa-tients.There were no difference in highest blood preasure and fastest heart rate between preoperative and in-traoperative results of each group.No perforation or intraoperative acute massive bleeding occurred.Intraop-erative acute minimal bleeding during ESD occurred in 9 patients in group A and 3 in group B,2 in group C and 2 in group D (P <0.05),but there were no differences among group B,C and D.The amount of submu-cosal injection of group A was(39.5 ±10.8)ml,which was more than that of group B(29.4 ±9.4)ml,group C(27.3 ±8.2)ml and group D(20.4 ±11.8)ml with significant difference.There were no differences a-mong group B,C and D,but there was less in group D than group B.The operation time of group A was(82.3 ±24.78 minutes),which was longer than that of group B (60.7 ±25.35minutes),group C (54.7 ± 31.72minutes)and group D(59.2 ±28.49 minutes),but there was no difference among B,C and D group. Conclusion Epinephrine-saline submucosal injection assiting ESD is safe and effective and reduces the op-eration time and bleeding than normal saline.The increase of the epinephrine-saline concentrations has not been found to be more beneficial.

Objective To sum up the experience of performing a laparoscope-assisted hemiorrhaphy for huge ventral hernia through small incision.Methods Clinical data were retrospectively analyzed for 18 cases of huge ventral hernia admitted from Jan 2009 to Sept 2009 undergoing laparoscope- assisted hernia mpair through small incision.Data renewed including the operational duration,missed hernia,length of the incision,serumal cyst,the length of hospital stay,chronic pain and the recidivation.Results Surgery was successful in all of the 18 cases,the operational time was(129±19) main,the length of the incision was(5.6±1.0) cm.Missed hemia were identified in 3 cases during the operation.One case:suffered from postoperative serumal cyst,the postoperative length of hospital stay was(5.1±1.2) days,postoperative incisional pain lasting for more than 3 months was identified in 1 case,there was no incisional infection and nor injury to intraabdominal organs,there was no operative mortahty,all the cases were followed-up for(8.6 ±1.6)months and there was no recidivation.Conclusions The laparoscope hemia repair with the subsidiary of micro-incision is effective and safe,and it reshapes the abdominal wall.

Objective To screen differentially expressed serum proteins by label-free quantitative proteomics in patients with atopic dermatitis,in order to discover serum protein markers for atopic dermatitis.Methods Serum samples were collected from 6 patients with atopic dermatitis and 6 healthy human controls.Then,the samples from the patients were pooled together,so with those from the controls.Proteins were extracted from the two joint serum samples followed by separation with one-dimensional sodium dodecyl sulfate polyacrylamide gel electropheresis (SDS-PAGE).Peptides were obtained by enzymolysis in protein gels,which were subsequently identified by high performance liquid chromatography tandem mass spectrometry.The Mascot software was used for database searching,and the Scaffold software for relatively quantitative analysis of proteins.Results Totally,76 proteins with a difference of greater than 1.5 folds were identified between the serum samples of patients with atopic dermatitis and controls.There were 50 up-regulated and 26 down-regulated serum proteins in the patients compared with the healthy controls.Among these differentially expressed proteins,26 were only detected in the sera of the patients,and 14 proteins in those of the controls.Conlusion Differences exist in the expression of serum proteins between atopic dermatitis patients and healthy people.

Objective To study the effect of pioglitazone on the differentiation and function of rat osteoclast-like cells (OLC), and to probe the relationship between activated PPARγ2 and osteoclasts. Methods On day 1 of OLC formation from nonadherent bone marrow ceils (BMC) obtained from rats induced by M-CSF and receptor activator of NF-кB ligand (RANKL), 1, 5 and 10μmol/L pioglitazone hydrochloride was added. RT- PCR was performed to determine the mRNA expressions of PPARγ2 and receptor activator of NF-кB (RANK) on day 3, 5 and 7 during incubation, the number of tartrate-resistant acid phosphatase (TRAP)-positive cells,the number of bone resorption pits and the ratio of its area on dentin slice were counted, the activity of TRAP and the mean fluorescence intensity of integrin β3 (CD61) of OLC were also measured. Results (1) The effect on the differentiation of OLC: The addition of pioglitazone at the start of the culture period induced a dose-dependent decrease in TRAP-positive OLC and the activity of TRAP (P < 0.01 or P < 0.05) ; the mRNA expression of PPARγ2 was up-regulated by 5 and 10 μmol/L pioglitazone in the early stage of incubation and attenuated with thematuration of OLC on the contrary, however, the expression of RANK was down-regulated by 5 and 10 μmol/L piolitazone in every stage of incubation (P < 0.05 or P < 0.01), combined with decrease in TRAP-positive OLC from day 3 by 10 μmol/L pioglitazone. (2) The effect on the function of OLC: the number of bone resorption pits and the ratio of its area on dentin slice were decreased in groups of 5 and 10 μmol/L pioglitazone (P < 0.01 orP < 0.05), no obvious change was noted in the group with 1 μmol/L pioglitazone compared with the control group; the mean fluorescence intensity of CD61 were down-regulated in groups of 5 and 10 μmol/L pioglitazone (P < 0.05 or P <0.01). Conclusion Activation of PPARγ2 pathway by pioglitazone could partially inhibit differentiation and function of OLC derived from rat BMC.

Background/Aims: To investigate postpartum hepatic flares and associated factors in highly viremic pregnant patients in the immune tolerance phase who adopted telbivudine (LdT) treatment in the last trimester to reduce vertical transmission of hepatitis B virus. Methods: Hepatitis B e antigen (HBeAg)-positive, highly viremic pregnant women were recruited for this prospective study. Treatment with LdT was started from 28 weeks of gestation. Virological and biochemical markers were examined before LdT treatment, antepartum and postpartum. Serial blood samples at the same time were collected to detect cytokines and cortisol (COR). Results: Fifty-six of 153 patients (36.6%) had postpartum hepatic flares, defined as a 2-fold increase in alanine aminotransferase 6 weeks after delivery. Age and the antepartum alanine aminotransferase and postpartum HBeAg levels were independent influencing factors of postpartum hepatic flares. Cytokines showed no regularity during or after pregnancy. Compared with the patients with no postpartum flares, the patients with flares had lower baseline interferon γ and COR levels (p=0.022 and p=0.028) and higher postpartum interferon γ levels (p=0.026). Conclusions A high proportion of highly viremic and immune-tolerant pregnant patients treated with LdT in the last trimester had postpartum hepatic flares, which implied that these patients entered the immune clearance phase after delivery. Thus, this may create an appropriate opportunity for re-antiviral therapy.

Prostate cancer is one of the most common malignancies in older men. Prostate cancer patients with distant metastasis often have a poor prognosis, and more than half of Chinese prostate cancer patients have developed distant metastasis at the time of initial diagnosis. In recent years, with the disclosure of the results of a number of global multi-center clinical trials, combination therapy and precision therapy have become two major themes in the treatment of metastatic prostate cancer (mPCa). The American Society of Clinical Oncology Genitourinary (ASCO-GU) Cancers Symposium is a grand meeting of the urologic oncology community. Several research advances reported at the meeting will help to update the treatment strategy of mPCa. This article interprets and comments on a number of milestone studies on mPCa treatment at the ASCO-GU 2022 annual meeting, with a view to providing help for the clinical treatment decisions of mPCa patients.

Objective:To evaluate the efficiency and safety of endoscopic submucosal tunnel dissection (ESTD) on treatment of early esophageal cancer with submucosal fibrosis.Methods:In the Department of Gastroenterology of Northern Jiangsu People′s Hospital from June 2015 to Feburary 2018, data of 87 patients undergoing ESTD or endoscopic submucosal dissection (ESD) for early esophageal cancer or precancerous lesion were collected with inclusion criteria of cancer size less than 1/3 circumference with submucosal fibrosis, which was confirmed by pathology. According to the degree of submucosal fibrosis, 60 patients had mild fibrosis (31 underwent ESTD and 29 underwent ESD), and 27 patients had severe fibrosis (16 underwent ESTD and 11 underwent ESD). The dissection speed, en bloc resection rate, complete resection rate, and the complications (including bleeding, muscularis injury, perforation, neck subcutaneous emphysema and esophageal stenosis) were compared between the two methods of dissection in the groups with same degree of submucosal fibrosis.Results:For patients with mild submucosal fibrosis, ESTD had a higher en bloc resection rate (96.8%, 30/31) and complete resection rate (96.8%, 30/31), and lower muscularis injury rate (6.5%, 2/31) than those of ESD [82.8% (24/29), 75.9% (22/29), and 17.2% (5/29), respectively, all P<0.05]. There was no difference in the dissection speed, incidence of intraoperative bleeding, perforation and postoperative esophageal stenosis between the two methods (all P>0.05), and no postoperative delayed bleeding or neck subcutaneous emphysema occurred. For patients with severe submucosal fibrosis, ESTD had a higher dissection speed (12.3±2.8 mm 2/min), and lower incidence of intraoperative bleeding (12.5%, 2/16), muscularis injury (18.8%, 3/16), perforation (6.3%, 1/16) and neck subcutaneous emphysema (6.3%, 1/16) than those of ESD [7.1±3.2 mm 2/min, 54.5% (6/11), 54.5% (6/11), 27.3% (3/11), and 27.3% (3/11)]. There was no difference in en bloc resection rate, complete resection rate, and the incidence of postoperative esophageal stenosis between the two methods, and no postoperative delayed bleeding occurred. Cancer recurred locally in 2 patients undergoing ESD and 1 patient undergoing ESTD at 12 months after the operation, and 1 patient undergoing ESTD developed metachronous cancer at 24 months after the operation. Conclusion:ESTD is safe and effective for endoscopic management of early esophageal cancer or precancerous lesion with submucosal fibrosis. Compared with standard ESD, the advantage of ESTD is more efficient for patients with mild submucosal fibrosis, and is safer for patients with severe submucosal fibrosis.
