Objective To evaluate the advantages and disadvantages of transabdominal myomectomy (TAM), transvaginal myomectomy (TVM) and laparoscopic myomectomy (LM). Methods We retrospectively reviewed the clinical data of 89 cases of TAM (Group TAM), 34 cases of TVM (Group TVM) and 62 cases of LM (Group LM). Results About the operation time, the Group LM occupied the first place (123 7 min?56 7 min), the Group TAM came second (90 5 min?31 1 min), and the Group TVM last (60 7 min?20 5 min), with significant differences among the three groups ( P 0 05), but the blood loss in both of the groups was much more than that in the Group TVM ( P 0 05), but markedly lower than that in the Group TAM ( P

Tigecycline is a new broad-spectrum antibiotic,which is the first glycyclines antibiotic used in clinic. Tigecycline is ac-tive against Gram-positive/negative bacteria and anaerobicbacteria, especially multidrug-resistant (MDR) pathogens. In this review, the literatures associated with tigecycline-induced coagulopathy published after 2005 were searched in Pubmed and the clinical charac-teristics as well as the research progress were summarized. The mechanism of tigecycline-induced coagulopathy was also explored. Cli-nicians should observe coagulation markers of patients during the treatment with tigecycline. If coagulation disorders or active bleeding occurs,tigecycline treatment should be stopped and symptomatic and supportive treatment should be given immediately.

Objective To investigate the effect of acupuncture combined with antidepressant on behavioral changes and 5-hydroxytryptamine 1A and 2A receptor ( 5-HT1AR and 5-HT2AR) mRNA expression in nucleus raphes dorsalis (NRD) of sleep deprivation depression (SDD) rats. Methods Eight normal Sprague Dawley (SD) rats were caged together without any stimulus or treatment, serving as the normal group. Thirty-two SD rats were given solitary raise for 21 days, together with chronic unpredictable mild stress ( CUMS) and rapid eye movement ( REM) sleep deprivation to establish the model. Twenty-eight rats completed the modeling successfully, and were divided into model group, acupuncture group, medicine group, and combination group, 7 rats in each group. Rats in the model group were given modeling treatment but without any intervention. Rats in the acupuncture group were given acupuncture on acupoint Yintang, Shenting and bilateral Taichong, acupuncture stimulation lasting 15 s every 10 min and acupuncture retention for 20 min in each day. Rats in the medicine group were given gastric gavage of Zoloft solution (0.83 mg·kg-1·d-1) and Alprazolam solution (0.067 mg· kg-1·d-1) , and rats in the combination group were given both acupuncture and medicine intervention. The intervention for the three intervention groups lasted for 7 days. Results Compared with the normal group, body weight, Open-field scores and sucrose preference of the model rats were significantly decreased on modeling day 7, 14, 21 (P<0.05). On modeling day 28, body weight and Open-field scores of each intervention group were significantly increased compared with those of the model group (P<0.05), and Open-field scores of combination group differed from those of acupuncture group and medicine group ( P<0.05). Only sucrose preference of combination group was improved significantly compared with the model group (P<0.05). Compared with the model group, NRD 5-HT1AR mRNA expression level was increased in the combination group (P<0.05), and NRD 5-HT2AR mRNA expression level was down-regulated in all of the three intervention groups ( P<0.05). Conclusion Acupuncture and antidepressant treatment covering 7 days can evoke rapid effect on SDD rats, which can improve the slow effect of antidepressant.

BACKGROUND AND OBJECTIVEThe actual evaluation of immunological function is significant for studing the tumor development and devising a treatment in time. The aim of this study is to evaluate the immunological function of advanced lung cancer patients systematically, and to discuss the clinical significance.

METHODSThe nucleated cell amounts of advanced lung cancer patients and the healthy individuals were counted. The immune cell subsets and the levels of IL-4, INF-gamma, perforin and granzyme in CD8+T cells by the flow cytometry were measured. The proliferation activity and the inhibition ratio of immune cells to several tumor cell lines were evaluated by MTT assay.

RESULTSThe absolute amounts and subsets of T, B, NK cells of advanced lung cancer patients were lower than the healthy individuals (P < 0.05); However, the proportion of regulatory T cells of advanced lung cancer patients (4.00 +/- 1.84)% was lower than the healthy individuals (1.27 +/- 0.78)% (P < 0.05). The positive rates of IFN-gamma perforin, granzyme in CD8+T cells decreased while them in IL-4 did not in the advanced lung cancer patients compared to the healthy control group (P < 0.05). The proliferation activity of immune cells, the positive rate of PPD masculine and the inhibition ratio to tumor cells in the advanced lung cancer patients was lower than the healthy subsets obviously (P < 0.05).

CONCLUSIONThere was a significant immune depression in the advanced lung cancer patients compared to the healthy individuals.

Objective:To investigate the effect of artificial dermis combined with KCI negative pressure suction device in the repair of scalp defect with skull exposure after the operation of scalp malignancy.Methods:From January 2016 to June 2018, 18 patients with scalp defect and skull exposure after scalp malignant tumor surgery were treated with artificial dermis combined with KCI negative pressure suction device.Results:Eighten patients had good wound healing after the first stage of surgery, and no infection occurred. The time for artificial dermis to complete granulation was 10-14 days, with an average of 12.1 days. After the second stage of skin grafting, the skin graft had a survival rate of 100%, with uniform color and good elasticity, without obvious scar hyperplasia or contracture. The postoperative follow-up period was 6 to 2 months, all the patients healed well without tumor recurrence, with good skin elasticity and friction-resistant, and they were satisfied.Conclusions:Artificial dermis combined with KCI negative pressure suction device is an effective and simple method to repair the scalp defect with skull exposure after tumor surgery.

ObjectiveTo investigate the characteristics of serum perfluoroalkyl substances （PFASs） exposure and potential influencing factors among community residents in Songjiang District， Shanghai. MethodsIn August 2021， residents who underwent routine health checkups in a community in Songjiang District， Shanghai were recruited as study subjects. The inclusion criteria were adult residents who had lived in the area for more than 3 years， had no occupational exposure history， no underlying diseases， were not pregnant， and were able to complete the questionnaire independently and sign the informed consent form. A questionnaire survey was conducted and venous blood samples were collected. The concentrations of 15 PFASs in serum were determined using ultra-high performance liquid chromatography-tandem quadrupole mass spectrometry （UPLC-MS/MS）. Ordered multi-class logistic regression， interquartile range （IQR）， and odds ratio （OR） were used to explore the influencing factors and risk magnitude of serum PFASs concentrations. ResultsOf the 15 PFASs， 14 were detected， and the detection rates of 7 PFASs were higher than 50%. The highest detected concentrations among the PFASs were PFOS （perfluorooctane sulfonate）， PFOA （perfluorooctanoic acid）， and PFHxS （perfluorohexane sulfonate）， with median concentrations of 48.61 μg∙L^-1， 37.29 μg∙L^-1， and 36.51 μg∙L^-1， respectively. The strongest correlation was between PFDA and PFUnDA （r=0.93， P<0.05）， followed by PFOS and PFDA （r=0.86， P<0.05）. Age， frequency of plastic product use， time spent indoors per day， personal annual income， tea consumption， and daily water intake were potential factors for exposure to PFASs. Among them， age was positively correlated with PFASs； tea consumption was positively correlated with PFNA and PFOA； PFHpA was negatively correlated with the frequency of plastic product use and personal annual income； and PFOS was negatively correlated with the time spent indoors per day. ConclusionThe exposure to serum PFASs among community residents in Songjiang District was relatively serious， and the main components were traditional PFOA， PFOS， and PFHx. Different sociodemographic characteristics had varying degrees of influence on the concentrations of PFASs in serum. The impact of PFASs exposure on the health of community residents deserves further investigation.
