OBJECTIVE:To prevent and reduce the occurrence of nosocomial deep mycosis.METHODS:The medical records of patients with nosocomial deep mycosis in the period from January2001to December2002in this hospital were ret?rospectively analysed.RESULTS:There were43patients with nosocomial deep mycosis,which accounted for10.54%of all nosocomial infections in the same period.The predilection sites were respiratory tract(34.88%)and digestive tract(30.23%). The main pathogen was Candida albicans(77.78%).All patients had serious underlying diseases and were treated with broad-spectrum antibiotics,and some of them had received adrenocortical steroids.CONCLUSION:Rational use of broad-spectrum antibiotics and adrenocortical steroids is the most important way to prevent deep mycosis and improve the prognosis.

OBJECTIVE:To evaluate the quality of the methodology of clinical research on Yinzhihuang injection in the treatment of icteruc virus hepatitis.METHODS:The methodology quality of77pertinent literatures was evaluated and analyzed according to the quality assessment criteria in the evaluation manual of Cochrane Reviewer's Handbook 4.2.2.RESULTS:Only 4 literatures were up to the related standards,2 of which were randomized controlled trials(RCT)and other 2 were semi-randomized controlled trials(CCT).All of the 4 studies were low quality(Grade C)researches,in which the biases on selectivity,practice,measurement and wastage were highly possible.CONCLUSION:More randomized controlled trials of high quality are needed to obtain reliable evidences on Yinzhihuang injection in the treatment of icteric virus hepatitis.

Background Studies showed that activation of microglia-derived nicotinamide adenine dinucleotide phosphate (NADPH) oxidase plays a key role in the neurodegenerative diseases and neural cell death in central nervous system.The effect of NADPH on cone degeneration have been determined in rd rats,its role in rod degeneration is relatively less studied.Objective This study was to study the expression of NADPH oxidase in the retinal degenerative process in rd mice and further explore its role in the photoreceptor degeneration.Methods rd Mice at postnatal day 8 (P8),P10,P12,P14,P16 and P18 were collected.The mice were sacrificed,and retinal sections,RNAs and proteins were prepared in above-mentioned time points.The expressions of the gp91 phox,a major subunit of NADPH oxidase,in transcript level and protein level in the retinas were semi-quantitatively detected by real-time PCR and Western blot respectively.Expression of gp91phox was localized in the rd retinas as ageing by immunohistochemstry,and the co-expression of gp91phox with CD11b,a specific marker of microglial cells,was assayed by immunofluorescent double labeling.The C57BL/6N mice were served as controls.The use and care of the animals complied with the Guideline of ARVO.Results Real-time PCR showed that gp91phox mRNA was not expressed in the retinas of C57BL/6N mice.Gp91phox mRNA was found to have less expressed in retinas of P8 rd mice.With aging,the expression level of gp91phox mRNA (gp91phox mRNA/β-actin) in rd mouse retinas was gradually increased with the highest level in P14 mice(1.136±0.370).A significant difference was seen in the gp91 phox mRNA expression among various groups of mice (F=17.81,P =0.00),and gp91phox mRNA expression was significantly elevated in P10,P12,P14,P16 and P18 rd mice compared with P8 rd mice(all at P＜0.05).The expression level of gp91phox protein (A value) in the retinas presented with a similar trend in the rd mice,with a significant difference among the various ages of rd mice and C57BL/6N mice (F =354.00,P＜0.01).The expression level of gp91 phox protein was increased in the rd mice in comparison with the C57BL/6N mice (all at P＜0.05).Immunochemistry revealed that the positive response cells for gp91phox increased in the inner layers of retinas in P10 rd mice and peaked in P14 mice.Immunofluorescent double labeling exhibited that gp91phox were seen to present a co-expression with CD11b,showing an orange fluorescence.Conclusions Expression of NADPH oxidase in the rctinas in the rd mice up-regulates and is parallels to the microglial activation and photoreceptor degeneration,suggesting that NADPH oxidase plays a role in the retinal dystrophy associated with microglial activation.

OBJECTIVETo explore the impacts on the life quality and the effect mechanism in the patients of allergic rhinitis (AR) treated with warm acupuncture in winter and summer.

METHODSTwo hundred and forty patients of AR were randomized into a summer and winter acupuncture group, a non-summer and winter acupuncture group and a western medication group, 80 cases in each one. In the two acupuncture groups, Dazhui (GV 14), Fengmen (BL 12), Feishu (BL 13), Pishu (BL 20) and Shenshu (BL 23) were selected. In the summer and winter acupuncture group, the warm acupuncture started at the first day of the three periods of hot season and the first day of the third nine-day period after the winter solstice. The treatment was given once every two days, continuously for 15 times. Totally, 30 treatments were required a year. In the non-summer and winter acupuncture group, the warm acupuncture was applied out of the three periods of the hot season and the third nine-day period after the winter solstice. The treatment was given once every two days and 30 treatments for a year. In the western medication group, cetirizine was taken orally, continuously for 30 days as one session. In the three groups, the treatment for 1 year was taken as one session. The second session started in the next year. Totally, 2 sessions were required. The score of rhinoconjunctivitis quality of life questionnaire (RQLQ) and the level of serum immunoglobulin E (IgE) were compared in the patients' of each group before treatment and in 1 and 2 sessions of treatment.

RESULTSAfter treatment, the scores of 7 domains, named activities, common complaints, practical problems, sleep, ocular symptoms, nasal symptoms and emotions were all improved as compared with those before treatment, in the patients of the three groups (all P < 0.05). After 2 sessions treatment, the results in the summer and winter acupuncture group were better than those in the other two groups (all P < 0.05), and the results in the non-summer and winter acupuncture group were better than those in the western medication group (all P < 0.05). After treatment, serum IgE level was lower averagely than that before treatment in the three groups (all P < 0.05). After 2 sessions treatment, the result in the summer and winter acupuncture group was lower than that in the other two groups (both P < 0.05), and the result in the non-summer and winter acupuncture group was lower than that in the western medication group (P < 0.05). After treatment, the total effective rate was 92.3% (72/78) in the summer and winter acupuncture group, better than 80.5% (62/77) in the non-summer and winter acupuncture group and 69.7% (53/76) in the western medication group (both P < 0.05).

CONCLUSIONThe warm acupuncture in both summer and winter achieves the definite efficacy on AR and the effect mechanism is relevant with reducing serum IgE level.

The data of arterial pressure and diameter were measured in vivo before and after normal anastomosis and tensional anastomosis in canine femoral arteries at different time intervals. The arterial compliance was calculated, and the exponential form C = bemPa was employed to fit the compliance (C)- average pressure (Pa) curve. The relationship between compliance and average pressure was determined. The results showed that the compliance of arteries decreased after anastomosis, and the compliance of arteries after tensional anastomosis was lower than that of normal anastomosis at different time intervals. It was decreased most markedly at 14 days after tensional anastomosis. This indicated that the distensibility of tensional anastomotic artery was decreased more markedly than that of normal anastomotic artery. The function of artery was evidently affected by tensional anastomosis.

Objective:To explore the feasibility and clinical value of sentinel lymph node (SLN) biopsy through cervix-uterine combined two-step injection with two tracers in patients with early stage endometrial cancer.Methods:From July 2019 to April 2021, a total of 73 patients, aged (54.2±3.3) year, who were preoperatively diagnosed as stage Ⅰ-Ⅱ endometrial cancer (including 56 low-risk patients and 17 medium-high risk patients) in Affiliated Hospital of Qingdao University were selected. According to the different sites of tracer injection, the patients were randomly divided into three groups: cervical injection group (25 cases): 1 ml of nano-carbon was used to inject at 3 and 9 o'clock in the cervix; uterine injection group (21 cases): the magnetic resonance imaging examination was performed to determine the location of the lesion, and 4 ml of methylene blue was injected into the uterine body at 2 sites where the lesion was located; combined injection group (27 cases): cervical injection of nano-carbon (1 ml) combined with uterine injection of methylene blue (4 ml). The SLN in all patients were identified under laparoscopy, removed, and followed by frozen pathological examination. Pathological ultra-staging was performed if the postoperative pathological outcome of SLN was negative. The total detection rate of SLN, bilateral pelvic SLN detection rate, sensitivity, negative predictive value, and location of SLN in each group were calculated and compared.Results:(1) In 73 patients with endometrial cancer, the overall detection rate of SLN was 88% (64/73), the detection rate of bilateral pelvic SLN was 67% (49/73), and the detection rate of para-aortic SLN was 49% (36/73). The overall detection rate of SLN (71%, 15/21) and bilateral pelvic SLN (43%, 9/21) in the intrauterine injection group were significantly lower than those in the cervical injection group [92% (23/25), 76% (19/25), respectively] and the combined injection group [96% (26/27), 78% (21/27), respectively; all P<0.05]; the detection rate of para-aortic SLN in the cervical injection group (28%, 7/25) was significantly lower than those in the intrauterine injection group and combined injection group [52% (11/21) and 67% (18/27), respectively; both P<0.05]. Among 73 cases with endometrial cancer, 9 had lymph node metastasis confirmed by postoperative pathological examination, 8 of them had lymph node metastasis detected by SLN and 1 had no lymph node metastasis detected by SLN, with a total sensitivity of 89% and a negative predictive value of 98%. The sensitivity and negative predictive value of cervical injection group and combined injection group were 100%, while the sensitivity and negative predictive value of intrauterine injection group were 67% and 95%. Among 56 low-risk patients, only one patient with lymph node metastasis was confirmed by postoperative pathology by SLN detection, and the metastasis rate was 2% (1/56), and the sensitivity and negative predictive value were 100%. Lymph node metastasis was confirmed in 8 of 17 patients (8/17) with a sensitivity of 88% and a negative predictive value of 90%. (2) A total of 459 SLN were detected in 73 endometrial cancer patients, with the highest proportion of external iliac (33.3%, 153/459).The obturator foramen was 25.3% (116/459), para-aortic 19.6% (90/459), iliac 12.0% (55/459), and presacral 9.8% (45/459). The proportion of para-aortic SLN in the cervical injection group was 12.4% (21/169), which were significantly lower than that in the intrauterine injection group and the combined injection group [27.4% (26/95) and 22.1% (43/195), respectively; both P<0.05]. (3) Pathological super-staging results: among 64 patients with negative SLN routine paraffin pathology, 4 cases of lymph node micro-metastases and 1 case of isolated tumor cell metastasis were detected, and the SLN micro-metastases rate was 8% (5/64), including 2 cases of low-risk patients and 3 cases of medium-high risk patients. Conclusions:SLN biopsy has high sensitivity and negative predictive value in patients with early endometrial cancer and could be used as an alternative to systematic lymph node dissection in low-risk patients. The SLN mapping through cervical-uterine combined injection could further improve the detection rate effectively and avoid the missed detection of positive para-aortic lymph node, especially for high-risk patients or patients with fundal tumor involvement.

Objective: To study the effect of color Doppler ultrasound (CDUS) combined with serum glucoside antigen 125 (CA125) on the diagnostic efficacy of patients with ovarian cancer. Methods: A total of 78 patients with ovarian tumors admitted to our hospital from February 2012 to June 2018 were enrolled. Among them, 38 patients with malignant tumors and 40 patients with benign tumors were tested for CDUS and serum CA125. The characteristics of CDUS images and serum CA125 levels in patients with malignant tumors were analyzed by pathological examination as the gold standard. The diagnostic efficacy of CDUS combined with serum CA125 level detection and separate examination was analyzed. Results: ⑴ Characteristics of CDUS images: the size, location, texture, blood flow signal, resistance index, ascites, peritoneal implant nodule or enlarged lymph node of patients with malignant tumors were significantly different from those of benign tumors (P<0.05). ⑵ Serum CA125 level: the serum CA125 level of patients with malignant tumors was higher than that of patients with benign tumors (P<0.05). ⑶ Diagnostic results: among 78 patients with ovarian tumors, 33 cases of malignant tumors were detected by serum CA125, 45 cases of benign tumors, of which 5 cases were misdiagnosed, and 10 cases were missed. For example, CDUS detected 35 malignant tumors and 43 benign tumors, of which 6 were misdiagnosed and 9 were missed. A total of 43 malignant tumors and 35 benign tumors were detected, of which 6 were misdiagnosed and 1 was missed. ⑷ Diagnostic efficacy: the accuracy of CDUS combined with serum CA125 level detection (91.03%) was higher than that of the two groups (80.77% and 80.77%), but the difference was not statistically significant (P>0.05); the sensitivity of CDUS combined with serum CA125 level detection was 97.37%. The two were independently examined by 76.32% and 73.68% (P<0.05). The specificity of CDUS combined with serum CA125 was 85.00%, with no significant difference between the two groups (80.05%, 87.50%) (P>0.05). Conclusions The serum CA125 level of patients with ovarian cancer is abnormally elevated. The characteristics of CDUS images are different from those of benign tumors, which can effectively identify benign and malignant tumors. CDUS combined with serum CA125 level detection can significantly improve the diagnostic efficacy, and they can be used to judge the disease and symptom , and provide guidance for treatment and prognosis assessment.
