Objective To introduce the techniques and specification of complete-block radical gastrectomy, and to compare with traditional radical gastrectomy in the operative time, surgical costs and postoperative complications. Methods Thirty gastric cancer patients meet the criteria were randomly divided into 2 groups. Group A: complete-block radical gastrectomy;group B: radical gastrectomy. Analysis and comparison were made on tumor site, time consuming of block, the proportion of gastrointestinal reconstruction, operative time, cost of block, pathological TNM stage, length of stay, postoperative complications and postoperative chemotherapy. Results Group A has longer operative time than group B (P<0.05). However, there was no significant statistical difference in the other indicators between these 2 groups. Conclusions Complete-block technology can separate cancer more completely during operation with the advantage of simplicity, low-cost, little effect on the subsequent operation. The incidence of postoperative complications and length of stay with the traditional surgery there was no significant difference.

This article provides the possible mechanism of acupuncture-moxibustion repair of gastric mucosal injury from central regulation and puts it forward that the nucleus of solitary tract is the primary regulation center for the injury repair and has the effect of collecting and integrating information. In addition, it is put forward that neural regulation is a main regulatory mechanism for the injury repair and besides, endocrine, immune and humoral regulations participates in the modulation and gastric mucosal repair involves a composite regulatory mechanism in which the central nervous system, neuroendocrine-immune network and neurohumoral regulation take part.

Objective To observe the effect of scalp acupuncture and rehabilitation training on the regulation of neuro-plasticity-associated protein MAP-2 in gerbils modelling cerebral ischemia and reperfusion.Methods Cerebral ischemia and reperfusion were modelled into thirty-six male gerbils.They were then randomly divided into a model group (A),a scalp acupuncture and rehabilitation training group (B) and a rehabilitation training group (C),each of 12 cases.The scalp acupuncture and rehabilitation training were administered daily to the gerbils in group B beginning 24 h after modeling,for 14 d.Any changes in Bederson scores were observed after one,7 and 14 days.On the 14th day the expression of MAP-2 around the infarct focus was detected using western blotting in all 3 groups.Results On the 7th day the average Bederson score in group B (1.81 ± 0.52) was not significantly different from that in group A (2.13 ± 0.49) or group C (2.00 ± 0.31) (P ＞ 0.05).At the end of the treatment,however,there were significant differences between the groups,with group B (0.47 ± 0.31) scoring significantly better than groups C (1.04 ± 0.63) and A (1.46 ± 0.72) (P ＜ 0.05).Group C was also significantly better than group A (P ＜0.05).The expression of MAP-2 as measured as integrated optical intensity (IOD) in group B (0.91 ±0.18) was significantly higher than that in group A (0.43 ± 0.21) and group C (0.67 ± 0.24) (P ＜ 0.05) ; so was group C compared to group A (P ＜0.05).Conclusion The scalp acupuncture combined with rehabilitation training can improve the recovery of motor function and enhance the expression of neuro-plasticity-associated protein MAP-2 in gerbils with after cerebral ischemia and reperfusion.

Objective To evaluate the clinical and pathological factors that may influence serum prostate specific antigen(PSA)level in patients with benign prostatic hyperplasia(BPH).Methods A total of 561 cases of BPH diagnosed by pathological examination following operation were analyzed retrospec- tively.The patients'mean age was(68.3?6.3)years.The International Prostate Symptom Score(IPSS)was 21.1?7.4;the quality of life(QOL)was 4.5?0.8;Qmax was(7.3?3.3)ml/s;prostate volume(PV) was(69.8?36.8)ml;andpost-void residue(PVR)was(81.9?105.8)ml.Results Of 561 cases,223 cases(39.8%)had serum PSA level at 4-10 ng/ml,and 91 cases(16.2%),over 10 ng/ml.The level of serum PSA was not significantly associated with age,IPSS,QOL,Qmax and PVR(r=0.08,0.03,0.06,0.04 and 0.09,respectively;P＞0.05),but significantly associated with prostate volume of BPH(r=0.42,P＜0.01).The level of serum PSA was significantly elevated in BPH patients with enlarged prostate volume (F=93.45,P＜0.05)and the history of acute urinary retention(x~2= 59.1,P＜0.01).Additionally,a significantly increased PSA level was noted in tissue specimens with glandular hyperplasia(x~2=16.14,P＜0.01)or necrotic loci in BPH patients(x~2=36.06,P＜0.01).Conclusions An elevated serum PSA level was observed in more than 50% of BPH patients undergoing surgical resection.Enlarged prostate volume,the history of acute urinary,retention,and tissue specimens with glandular hyperplasia or necrotic foci are considered to be the main causes leading to elevated PSA level in BPH patients.

Objective To approach the efficiency and feasibility of preserving the fertility for patients with placental site trophoblastic tumor ( PSTT ).Methods Totally 2 086 cases of gestational trophoblastic neoplasm ( GTN) patients registered in Peking Union Medical College Hospital between 1998 and 2013.Fifty-seven of them were PSTT patients , 40 cases of which suffered hysterectomy , the rest 17 PSTT patients who preserved their fertility were analyzed retrospectively.The computerized database of clinical and pathological reports was reviewed in this cohort.Results The clinical manifestation of PSTT was not specific compared to other types of GTN.The average age of the 17 patients was 29.5 years old (range 22-39 years).The most common antecedent pregnancy was term birth (8 cases), the others were spontaneous abortion in 4 case, artificial abortion in 3 cases and molar pregnancy in 2 cases.The baseline serum β-hCG was slightly elevated and 12 patients (12/15) were less than 1 000 U/L.In this cohort, nine of the patients were in stage Ⅰ, while the other eight cases were in stage Ⅲ .The patients suffered conservative surgery, including dilation and curettage of uterus in 7 cases, open abdomen uterine lesion excision in 4 cases, laparoscopic uterine lesion excision in 3 cases, hysteroscopic uterine lesion excision in 1 case, and pulmonary lobectomy in 2 cases.Two of the patients didn′t received chemotherapy , while the other 15 cases suffered combination chemotherapy.Compared with 40 patients who suffered hysterectomy during the same interval , fertility preservation group did not result in poor outcomes or high risk of relapse rate.Six subsequent pregnancies happened after the therapy , two of them were during their second-trimester, while four patients had healthy babies by vaginal delivery in two and cesarean section in two .The scar of the uterus was fairly well during the cesarean sections.Conclusions Reservation of fertility therapy could be considered in highly-selected patients for young women who strongly desired to preserve their fertility and with localized lesion.Exactitude follow-up after therapy should be recommended.Contraception should also be recommended for at least one year after the chemotherapy.Vaginal delivery could be an option for the future pregnancies.

OBJECTIVETo observe anti-cancer effects of Jianpi Jiedu Recipe (JJR) on liver cancer (LC) rats with Pi deficiency syndrome (PDS) and its relation with the third complementary-determining region gene spectratyping of TCRVβ-chain (TCRVβCDR3).

METHODSRats were divided into 8 groups according to random digit table, i.e., the blank control group (normal), the PDS group, the LC model group, the LC-PDS group, high, middle, and low dose JJR groups (75.00, 37.50, 18.75 g/kg, respectively by gastrogavage, once per day), the thymus pentapeptide group (5 mg/kg, intramuscular injection, twice per week), 8 in each group. Rats in the normal group were administered with physiological saline by gastrogavage once per day. PDS rat model was prepared by bitter-cold purgation. LC model was prepared by orthotopic transplantation method. Twenty gene subfamilies of TCRβCDR3 in the thymus, liver, and LC tissues were detected by Gene Scan.

RESULTSHigh and middle dose JJR could postpone the growth of LC volume (P < 0.05), with equivalent liver index and thymus index to those of the normal group (P > 0.05). In thymus and liver tissue of the normal group, the number of clones (20 and 19), gene fragment number (220 and 113), Quasi-Gaussian distribution ratio of TCRVβCDR3 gene repertoire (100.0% and 42.1%), and fragment fluorescence peak area (6,539 ± 2,325 and 1,238 ± 439) were at the highest level among the 8 groups. TCRVβCDR3 expressions in thymus and liver tissue of high and middle dose JJR groups were approximate to those of the normal group. They were in the middle of the thymus pentapeptide group, the PDS group, the LC model group, and poorest in the LC-PDS group. TCRVβCDR3 in liver tissue expressed the best in the thymus pentapeptide group.

CONCLUSIONJJR might inhibit the growth of LC cells, and its mechanism might be related to enhancing TCRVβCDR3 spectratype expression.
