Objective To explore applied characteristics of the prolene hernia system(PHS) in inguinal hernioplasty, and management during and after operation, and long-term effect of this kind of hemioplasty in aged patients. Methods 69 aged patients using PHS were followed and analyzed retrospectively. Results Tension-free inguinal hernioplasty with the PHS were performed in 69 aged patients of groin hernia. Operative time ranged from 45min to 160min. Post-operatively, 3 patients developed gentle scrotal swelling, and 20 patients had been adminis- tered anodyne for pain of incision, and 12 cases experienced retention of urine, 1 case developed pneumonia, and 2 cases oeeurred incisional infection and gore. 68 cases of them recovered daily life about 2 to 3 weeks after operation. During follow-up period from 6 months to 77 months,there was no recurrence of inguinal hernia and no pain in in-guinal region, but 2 patients feel discomfort sporadically. Conclusion The PHS strengthens the myopectineal orifice and seals up-area of it,so the system is especially preferred in treating aged patients of groin hernias who have some defectsof anatomic structure in inguinal region. The local anaesthesia is also suitable for this kind of hernioplasty in aged patients.

Objective To study the correlation between serum adiponectin along with insulin resistanee and vascular dilation function in patients with different rates of glucose metabolism.Method A total of 83 patients aged 50-65 years,including 17 with normal glucose tolerance(NGT),22 with impaired fasting glucose (IFG),23 with impaired glucose tolerance(IGT)and 21 with diabetes(DM)were enrolled. Serum adiponectin was measured,and homeostasis model assessment for insulin resistance index (HOMA-IR)and B cell function index were used to evaluate the function of insulin secretion before and during oral glucose tolerance test(OGTr).The brachial artery responses to flow-mediated endothelium-dependent vascular dilation(EDVD)and nitroglycerin-mediated vascular dilation (EIVD) were evaluated by using the vascular ultrasound with high resolution.Results The serum adiponectin and EDVD decreased that the degrees of reduction from slightness to greatness were in turn from NGT,IFG,IGT to DM,whereas,the insulin resistance index (HOMA-IR) increased just in reverse order.Adiponectin was negatively associated with HOMA-IR(r=-0.353,P<0.01)but positively associated with EDVD and EIVD(rl=0.391,r2=0.375,P<0.01),and was not associated with HOMA-B.On the other hand,EDVD was not associated with HOMA-IR(P>0.05).In a multiple regression analysis with a stepwise manner to predict adiponectin concentration and EDVD.HOMA-IR was supposed to predict adiponectin concentration.Meanwhile APN but not HOMA-IR was used to predict EDVD(P<0.05).Condusions The decrease in serum adiponectin,endothelial dysfunction and insulin resistance can be observed in the early stage of impaired glucose metabolism. Serum adiponectin concentration appears to be associated with vascular function and insulin resistance.The association between serum adiponectin concentration and vascular function seems to be independence from its link with insulin resistance index.

Objective To investigate the effect of propofol on ketamine-induced cognitive dysfunction and neuronal apoptosis in hippocampus in aged rats. Methods Thirty-two male SD rats aged 18-24 months weighing 380-470 g were randomly divided into 4 groups ( n = 8 each) :control group (group C);propofol group (group P);ketamine group (group K) and propofol + ketamine group (group PK). Propofol 30 mg·kg-1·h-1 or/and ketamine 40 mg· kg-1·h-1 were infused for 2 h once a day for 7 consecutive days. After the last day of drug administration cognitive function was assessed using Morris water maze (escape latency and the number of animals' swimming across the platform). The animals were sncrificed after water naze test and their hippocampi were removed for determination of neuronal apoptosis (by TUNEL) and caspase-3 expression (by immuno-histochemistry) in hippocampal CA1 region. Results There was no significant difference in escape latency and the number of the animals,swimming across the platform, the neuronal apoptotic rate (the number of apoptotic neurons/the number of total neurons) and caspase-3 expression between group C and P. In group K and PK the escape latency was prolonged,the number of animals' swimming across the platform was decreased, neuronal apoptotic rate increased and the caspase-3 expression up-regulated as compared with group C. The ketamine-induced changes were significantly attenuated by coadministration of propofol in group PK. Conclusion Coadministration of propofol can ameliorate ketamine-induced cognitive dysfunction and hippocampal neuronal apoptosis.

Objective To observe the effect of lipopolysaccharide (LPS)-mediated infection during pregnancy on the expression of mineralocorticoid receptor (MR) and density of dendritic spines in CA1 region of the dorsal hippocampus of rat offspring,so as to explore the mechanisms for learning and memory injury of rat offspring which were infected during prenatal period,then to provide scientific experimental evidence for the prevention of prenatal infection-induced delayed neuropsychiatric sequelae which contributed to learning and memory dysfunction.Methods Ten-week-old female Sprague-Dawley rats (n =30) were matched with male rats (1 ∶ 1).Pregnant rats were randomly divided into a control group (n =10) and an experimental group (n =20).The pregnant rats in experimental group were treated with LPS (66 μg/kg,intraperitoneally),and the pregnant rats in control group were intraperitoneally injected with same volume of saline on gestational day 10.On postnatal day 48,Morris water maze was used to estimate the ability of learning and memory;the brain tissues of offspring were taken and paraffin sections were stained with hematoxylin eosin (HE) for histological observation of CA1 region of the dorsal hippocampus;frozen sections were treated with indirect immunofluorescence to observe the expression of MR in CA1 region of the dorsal hippocampus;Golgi-Cox method was used to observe the density of dendritic spines of CA1 region.Results In Morris water maze test,from the third day the time of escape latency in experimental group [the 3rd day:(42.603 ± 9.837) s;the 4th day:(30.222 ± 9.789) s;the 5th day:(28.808 ± 12.526) s] was significantly higher than that of the control group [the 3rd day:(28.078±14.088) s;the 4th day:(20.692±13.099) s;the 5th day:(14.632 ±11.624) s] (the 3rd day:t =-3.274,P＜0.01;the 4th day:t =-2.257,P ＜0.05;the 5th day:t =-3.213,P＜0.01);the swimming time in the target quadrant [(14.660 ± 7.337) times] and the number of crossing platform [(0.933 ± 0.704) times] in experi mental group were significantly decreased compared with those of the control group [time:(23.820 ± 6.321) s;num bers:(2.000 ± 0.756) times] (t =3.663,4.000,all P ＜ 0.01).Hematoxylin eosin staining showed that the nerve cells of the hippocampus in the control group distributed in order,nucleuses were round or oval,nucleoli were obvious,and chromatins were homogeneous;but the cells in the experimental group distributed in disorder and pathological changes were detected,such as cellular swelling,necrosis and obvious nuclear pyknosis.By immunofluorescence staining,the average optical density (AOD) of MR in CA1 region decreased significantly in the experimental group (0.067 ± 0.017) compared with that of the control group (0.083 ± 0.009) (t =2.644,P ＜ 0.05).In Golgi-Cox method,the density of dendritic spines in experimental group [(7.705 ± 0.791)/10 μm] was below that of the control group [(9.655 ± 1.391)/10 μm] (t =3.852,P ＜ 0.01).Conclusions LPS-mediated infection during pregnancy might lead to hippocampus-dependent learning and memory dysfunction which might be associated with the reduced expression of MR and the low density of dendritic spines in CA1 region of the dorsal hippocampus.

Objective To evaluate the effects of the schistosomiasis control mode(“Hubei mode”)that includes“compre-hensive measures in a whole endemic county”,“co-action of Health Ministry and Province”and“replacing cattle with machine”in Hubei Province. Methods The data of schistosomiasis control in Hubei Province from 2008 to 2012 were collected and a data-base including the annual schistosome infections of human and cattle,acute schistosome infection,outbreak of schistosomiasis en-demic,schistosome infected Oncomelania hupensis snails,and other prevention indicators was established and analyzed by using SPSS. Results Compared with 2008,in 2012,the infection rates declined by 64.91%and 88.63%in human and cattle respec-tively. The area with snails decreased from 5 423.85 hm2 in 2008 to zero. There were no acute schistosomiasis patients and out-break of schistosomiasis endemic. Conclusion The schistosomiasis control mode(“Hubei mode”)is effective significantly.

Objective:To explore the effect of different hemoperfusion times on the recovery of serum cholinesterase (ChE) in patients with severe acute oral organophosphorus pesticide poisoning (AOPP).Methods:This was a retrospective case-control study. Patients with severe AOPP admitted to our hospital were identified between January 2010 and December 2019. The clinical information of patients with severe AOPP was collected between January 2010 and December 2019, the patient's ChE vitality levels were collected on admission, at 1, 3 and 5 days after admission, and the sex, age, oral poison volume, and related treatments were recorded as well. The relationship between ChE, different HP treatment times and patients without HP treatment was analyzed by generalized estimation equations and multiple comparisons afterward.Results:A total of 159 patients with severe AOPP were included in our study. Among them, 60 (37.74%) patients were male and 99 (62.26%) were female, with a median age of 33 years old (range 13-75 years old). The median oral dose of OPs was 75 mL (range 15-500 mL). Multivariate analysis results showed that in the unadjusted generalized estimation equation, compared with patients without HP treatment, the average ChE value of patients with single HP treatment was 745.6 U/L higher (95% CI: 467.09 - 1024.1; P<0.01), the average ChE value of patients with 2 times HP treatment was 565.81 U/L higher (95% CI: 384.25-747.36; P<0.01), and the average ChE value of patients with 3 times HP treatment was 43.86 U/L higher (95% CI: 420.71-1 067.01; P<0.01), the differences were all statistically significant. After adjusting the amount of oral OPs at admission, age and PSS score in the multiple generalized estimation equations, the results showed that whatever single HP treatment or multiple HP treatment, the recovery rate of ChE was significantly faster than those without HP treatment. And the multiple comparison results of multiple models showed that the difference between 3 times HP treatment and 1 to 2 times HP treatment was not statistically significant, and the average difference between 2 times HP treatment and single HP treatment was also not statistically significant. Conclusions:Hemoperfusion therapy can accelerate the recovery rate of ChE in AOPP patients; Whatever single HP treatment or multiple HP treatments, the recovery rate of ChE in AOPP patients has no significant difference.

Objective To evaluate the efficacy of cold preservation solution containing desferrioxamine (DFO) in protecting the rat hearts.Methods Pathogen-free male Sprague-Dawley rats,weighing 300-350 g,were used in the study.Thirty-two isolated rat hearts were equally and randomly divided into control group (C group) and DFO group using a random number table.Hearts of rats were stored for 6 h in 4 ℃ histidine-tryptophan-ketoglutarate (HTK) solution in group C.DFO was added to HTK solution (DFO concentration 100 μmol/L),and hearts of rats were stored for 6 h in 4 ℃ HTK solution in group DFO.At 6 h of cold storage,creatine kinase and lactate dehydrogenase activities in the cold preservation solution were determined.Myocardial specimens were obtained from the apex,cut into sections which were stained with haematoxylin and eosin,and examined under a microscope.The pathological changes of myocardial tissues were scored.The content of malondialdehydc in myocardial tissues was determined using thiobarbitnric acid method,and hypoxia-inducible factor-1α protein and mRNA expression in myocardial tissues was detected by real-time reverse transcriptase polymerase chain reaction and Western blot.Results Compared with group C,the creatine kinase and lactate dehydrogenase activities in the cold preservation solution,malondialdehyde content in myocardial tissues,and pathological scores were significantly decreased,and the expression of hypoxia-inducible factor-1α protein and mRNA expression in myocardial tissues was significantly up-regulated in group DFO (P＜ 0.05).Conclusion Cold preservation solution containing DFO can protect the rat hearts effectively,and the mechanism is related to up-regulation of the expression of hypoxia-inducible factor-1α.

Purpose To investigate the clinicopathological characteristics and differential diagnosis of spindle cell rhabdomyosarcoma ( SCRM) . Methods Three cases of SCRMs were analyzed by gross examination, microscopy and immunohistochemistry. Relevant lit-eratures were reviewed to summarize the diagnostic features of SCRM and its differential diagnosis. Results All the 3 cases were male infants aged from 2 days to 4 years. 2 cases were located in paratesticular and 1 in back. Tumors were all well-circumscribed but unen-capsulated, with white-gray cut surface, firmed and sized 2. 0 to 6. 0 cm in diameter. Histologically, tumors displayed invasive growth but were well-circumscribed. Tumor cells were spindle to round with eosinophilic cytoplasm and fascicular, storiform, wavy appear-ance. Horizontal structure and striated muscle brood cells were observed in some cells or local regions. A small amount of collagen fi-brils were observed in the mesenchymal components. The nucleus were long or fine wavy with unconspicuous nuclear atypia, mitosis could be occasional observed. Immunohistochemically, tumor cells were positive for vimentin, desmin, myogenin and MyoD1. CK,α-inhabin, AFP, CD34 and S-100 were negative. Conclusions SCRM is a rare and new type of rhabdomyosarcoma that commonly oc-curred in infant. It should be differentiated from other tumors, such as infantile fibromatosis, congenital fibrosarcoma, fibrosarcoma, leiomyosarcoma, triton tumor, malignant melanoma of promoting the fibrous tissues.
