Objective:To study the clinical characteristics of neonatal community-acquired Novel Coronavirus (COVID-19) Omicron variant infection.Methods:From March 30 to May 15, 2022, the epidemiological characteristics, clinical manifestations and outcomes of neonatal cases of community-acquired COVID-19 Omicron variant infection admitted to the isolation ward of our hospital were analyzed.Results:A total of 7 neonates infected with community-acquired COVID-19 Omicron variant were treated, including 3 males and 4 females. All of them were term infants with clear epidemiological exposure history. The infection was originated from caregivers of close contact (parents or babysitters). The main clinical symptoms was upper respiratory tract infection, including fever (6 cases), nasal congestion (6 cases), cough (5 cases), runny nose (2 cases), poor appetite (2 cases) and diarrhea (1 case). On admission, no abnormalities were found in blood routine examination and C-reactive protein (CRP). All but one case had normal serum amyloid A (SAA). No obvious abnormalities were found on chest X-ray. All patients were isolated in single-patient rooms after admission. They received standard symptomatic treatment and regular nucleic acid tests. The first negative nucleic acid results came on median 17 d(8~26 d) after the onset of the disease. The patients were discharged after two consecutive (24 h apart) nucleic acid tests with CT value ≥35 and continued health-monitor at home. On discharge, 5 patients had nasal congestion and 2 of them had cough. During the follow-up 4~6 weeks after discharge, all patients gradually recovered without positive nucleic acid results.Conclusions:All 7 neonates with community-acquired COVID-19 Omicron variant infection have epidemiological exposure history. The main clinical symptoms are long-lasting upper respiratory tract infections. It takes a relatively long time for the nucleic acid to turn negative, however, the overall short-term prognosis is good.

Epithelioid hemangioendothelioma (EHE) is a rare malignant vascular tumor. Its malignancy is between benign hemangioma and highly malignant angiosarcoma. It originates from vascular endothelial cells or pre-endothelial cells. It is characterized by the proliferation of vascular endothelial cells with a skin-like or histiocyte-like appearance. The incidence of EHE is less than 1% in all vascular tumors, and it can occur in multiple parts of the body, most often in the liver, followed by simultaneous involvement of the liver and lung, the lung alone, and the bone alone. At present, there is no report of epithelioid hemangioendothelioma diagnosed by bone marrow cell morphological examination in China. In this case, abnormal cells were found through bone marrow cell morphological examination, which guided the direction of further diagnosis and treatment. And finally the patient was diagnosed as epithelioid hemangioendothelioma. The bone marrow cell morphological examination can provided an important basis for clinical diagnosis and treatment. Epithelioid hemangioendothelioma needs to be differentiated from a variety of benign and malignant angiogenic tumors, especially other types of epithelioid angiogenic tumors. At present, it has been found that the disease has characters of cytogenetic and molecular biological abnormalities. Combined with histopathological morphology and immunohistochemical examination, we can make the diagnosis and differential diagnosis.

OBJECTIVETo compare the difference in the therapeutic effects on ovulation disorder in polycystic ovary syndrome (PCOS) between the combined therapy of electroacupuncture and clomiphene and the single medication of clomiphene and to explore the effect mechanism.

METHODSA total of 80 patients of PCOS were randomized into an acupuncture plus medication group (40 cases) and a medication group (40 cases). In the medication group, since the 5th day of menstruation or medicine-withdrawal bleeding, clomiphene was prescribed for oral administration, continuously for 5 days. In the acupuncture plus medication group, the medication was the same as the medication group. Additionally, 30 min electroacupuncture (continuous wave, 2 Hz) was applied to Qihai (CV 6), Guanyuan (CV 4), Zigong (EX-CA 1), Dahe (KI 12), Sanyinjiao (SP 6), Zhongji (CV 3), Diji (SP 8), Shenshu (BL 23), Sanjiaoshu (BL 22) and Ciliao (BL 32), etc. The treatment started on the 5th day of menstruation or medicine-withdrawal bleeding, once every two days, 3 times a week. One cycle of menstruation or 1 month was taken as one course. The treatment cycles were 3 months in the two groups. The level of estradiol (E) and progesterone (P) in the serum, the endometrial thickness and morphology, ovulation rate and clinical pregnancy rate, as well as the clinical therapeutic effects were compared after treatment in the two groups.

RESULTSTwo cases were dropped out because the herbal medicine was taken simultaneously in the acupuncture plus medication group. In the medication group, the medication was discontinued in 3 cases due to gastrointestinal adverse reactions. The total effective rate was 86.8% (33/38) in the acupuncture plus medication group, better than 64.9% (24/37) in the medication group (<0.05). The ovulation rate in the acupuncture plus medication group was higher than that in the medication group [(86.8%, 33/38) vs (64.9% 24/37), <0.05]. The pregnancy rate in the acupuncture plus medication group was higher than the medication group in tendency, without significant difference [21.1% (8/38) vs 16.2% (6/37), >0.05]. After treatment, the results of endometrial thickness and morphology (A-type rate) in the acupuncture plus medication group were better than those in the medication group (<0.01, <0.05). After treatment, regarding the levels of E and P in the serum in the window period of implantation, the results in the acupuncture plus medication group were higher remarkably than those in the medication group (both <0.01).

CONCLUSIONThe combined intervention of electroacupuncture and clomiphene achieves the definite effects of ovulation and pregnancy promotion in PCOS. It remarkably increases the levels of E and P in the serum, the endometrial thickness and A-type rate. The therapeutic effects of the combined intervention are remarkably better than those of the simple application of clomiphene. This combined intervention is safe and tolerable for the adverse reactions. The effect mechanisms may be related to the improvements of estrogen, progestin and endometrial receptivity.

Objective To explore the factors related to the severity of disease symptoms in patients with acute leukemia (AL). Methods 198 AL patients with symptoms of disease (anemia, bleeding, infection, fever, etc.) from September 2013 to July 2016, were evaluated by the questionnaires of self-rating anxiety scale (SAS), self-rating depression scale (SDS), eysenck personality questionnaire (EPQA), Toronto alexithymia scale (TAS), family environment scale (FES), self-rating scale of illness conception and health seeking behavior (ICHSB). The results were compared with 198 healthy volunteers. Results The scores of SDS, SAS, factorⅠin FES, factor Ⅲ in FES, factor Ⅳ in FES, nervous and the total scores of EPQA, factor Ⅱ in TAS, factor Ⅱ in ICHSB were significantly higher in AL patients than those in healthy subjects [(41.09 ±6.85) scores vs. (36.74±6.99) scores, t=2.150, P=0.031; (38.64±7.51) scores vs. (31.79±7.57) scores, t= 3.327,P=0.001;(2.38±1.54) scores vs. (5.18±1.33) scores, t=3.319, P=0.001;(3.31±1.82) scores vs. (2.23±1.99) scores, t= 3.325, P= 0.001; (2.41±1.62) scores vs. (5.75±1.51) scores, t= 3.332, P= 0.001; (14.14±5.37) scores vs. (11.01±5.51) scores, t= 5.179, P= 0.000; (42.97±7.10) scores vs. (40.41±6.51) scores, t= 2.930, P=0.004;(22.97±4.57) scores vs. (21.54±4.13) scores, t=2.926, P=0.004; (16.37±3.89) scores vs. (15.92± 3.93) scores, t= 2.104, P= 0.034]. The difference was statistically significant (P< 0.05). The risk factors of AL were SAS (95 %CI= 1.064-1.210, P= 0.001), factor Ⅲ in FES (95 %CI= 1.104-1.694, P= 0.004), age (95 %CI= 1.027-1.094, P= 0.001), factor Ⅱ in TAS (95 %CI= 1.046-1.352, P= 0.005), besides, education level (95 %CI= 0.708-0.866, P= 0.001) acted as the protective role. Conclusions AL patients tend to the psychological problems such as depression, anxiety. Those will show much severer symptoms as a consequence of lacking of family warmth and concern, low expression of emotion, lacking of organization, low economic capacity, tension, and lacking of the ability to distinguish between emotion and physical feelings.

Objective To explore the related factors of common postoperative complications after cranioplasty. Methods From November, 2009 to June, 2013, a total of 211 patients after cranioplasty were reviewed. The conventional two-dimensional titanium alloy was used. The incidence of scalp effusion, seizure and spontaneous intracerebral hemorrhage were recorded, and the related factors including gender, age, primary disease, skull defect site, attack time, concomitant hydrocephalus and intraoperative dural damage were analyzed. Results The incidence of these complications was 4.7% (10/211) in total. There were four cases with scalp effusion, five cases with seizures and one case with spontaneous intracerebral hemorrhage. The scalp effusion was related to hydrocephalus (χ2=4.804, P=0.028) and intraoperative dural damage (χ2=7.510, P=0.006). Seizure and spontaneous intracerebral hemorrhage were not related with any factors above (P>0.05). Conclusion The occurrence of postoperative scalp effusion can be reduced by repairing intraoperative dural damage, and dealing with extreme hydrocephalus timely.

Objective To study the co-effects of methylene blue(MB) and exposure with the cold light source on cell DNA damage, and to explore the mechanism involved. Methods The alkaline single cell gel electrophoresis was used to determine cell DNA damage. Apoptosis of the cells was determined by flow cytometry analysis using Annexin V-FITC/PI staining. DCFH-DA probe was used to determine endocellular Reactive Oxygen Species (ROS). Results The levels of DNA damage in the SGC7901 adenocarcinoma cells treated with methylene blue in the light were significantly increased compared to that of control ( F = 8.39, P＜0.05 ). The DNA damage levels were related to the length of time of light exposure, and the damage was recovered to a certain level after light withdrew. Cell apoptosis ( x2=7.71,P ＜0.05)and endocellular ROS level (F = 34.11, P＜0.01＝ increased significantly in the exposure group. Conclusions Methylene blue chromoendoscopy can induce DNA damage and cell apoptosis, and the mechanism may be associated with ROS produced by the photochemical reaction.

objective To assess the DNA damage of radiation workers in different grade hospitals,and to explore the correlation between the types of work or work time and the levels of DNA damage.Methods DNA single strand break were detected by using alkaline single cell gel electrophoresis(SCGE),and the comet was analyzed with CASP(Comet Assay Software Project).TDNA,TL,TM and OTM were calculated.Results The parameters of SCGE in the radiation greup were higher than those of control group(F=3.93,P<0.01).The significant difference was found not only among the different types of work or difierent work time,but also among the different grade hospitals(F=1.83,1.9 1,P<0.05).Conclusions Various levels of DNA damage could be detected in the radiation workers of the two hospitals.DNA damage of radiation workers is less serious in the higher-grade hospital than the lower grade one.Different types of work or work time might affect the DNA damage level.
