Objective To detect the protein expression of gonadotropin-releasing hormone (GnRH) and its receptor (GnRH-R) in various endometrial tissues, and to investigate its significance. Methods Immunohistochemistry was employed to analyse the protein expression and localization of GnRH and GnRH-R from endometriosis(EMS), endometrial hyperplasia, endometrial carcinoma and control group. Results GnRH and GnRH-R are expressed at the protein level in all eutopic endometrium, in 50% ectopic endometrium and 92.3% endometrial hyperplasia, while the expressional rate in endometrial carcinoma are 58.8% and 82.4%, respectively. The majority of GnRH and GnRH-R existed in the plasma of glandular epithelium cells and some stroma cells. Conclusions There exists GnRH and its receptor proteins in endometrial tissues, and their abundant expression in endometriosis, endometrial hyperplasia and in endometrial carcinoma may imply that they could be used in clinical diagnosis and treatment.

Objective To investigate the effects of narrow-band ultraviolet B (NB-UVB) on the expression of keratin 17 (K17) in the human keratinocyte cell line HaCaT.Methods Cultured HaCaT cells were irradiated with different doses (0,50,100,200,400 mJ/cm2) of NB-UVB followed by additional culture for 6,12 and 24 hours respectively.To explore the mechanisms underlying the effects of NB-UVB on K17 expression,some HaCaT cells were pretreated with PD98059 (an inhibitor of mitogen-activated protein kinase kinase) followed by UVB radiation and additional culture as described above.Cell counting kit-8 (CCK 8) was used to evaluate the proliferation of,real time PCR to measure the mRNA expressions of K17 in,and Western blot to determine the protein expression of K17,Erk1/2 and phosphorylated Erk1/2 in,HaCaT ceils.Results Both the proliferation of and K17 expression in HaCaT cells were promoted by NB-UVB radiation at low doses (50,100 mJ/cm2),but inhibited by NB-UVB radiation at high doses (200,400 mJ/cm2).Significant differences were observed for the proliferative activity between HaCaT cells irradiated with NB-UVB at 100 or 400 mJ/cm2 and unirradiated HaCaT ceils at 12 and 24 hours (P ＜ 0.01 or 0.05).The phosphorylation of Erk1/2 was upregulated by NB-UVB radiation at 100 mJ/cm2,but downregulated by that at 400 mJ/cm2,and the upregulation induced by low dose NB-UVB could be suppressed by blocking the Erk 1/2 pathway.Conclusion The effects of NB-UVB radiation on K17 expression may be modulated by the Erk 1/2 pathway.

Common bile duct stones are a common of digestive system disease, and as one of the long-term complications after Billroth II subtotal gastrectomy, it has attracted more and more attention from clinicians. Common bile duct stones after Billroth II subtotal gastrectomy have a complex pathogenesis, including neurological, humoral, and mechanical factors. Even though there are many methods to remove stones, there are still controversies over the selection of digestive endoscopy, surgical operation, or percutaneous transhepatic approach. Clinicians should fully evaluate the specific conditions of patients and formulate individualized treatment regimens to achieve the best treatment outcome.

At present, the epidemic of coronavirus disease 2019 is still serious, and the prevention and control of this epidemic is taken seriously throughout the country. As one of the most common acute abdominal diseases in hepatobiliary surgery, gallstones with acute cholecystitis has sudden onset and rapid progression and thus requires early diagnosis and timely and effective treatment. During the prevention and control of the epidemic, patients should be admitted properly to reduce nosocomial infection. Gallstones with acute cholecystitis is often accompanied by pyrexia, and therefore, the presence or absence of severe acute respiratory syndrome coronavirus 2 infection should be clarified. Treatment regimen should be selected appropriately and individualized treatment measures should be developed. While ensuring that patients receive timely and effective diagnosis and treatment, hospitals should adopt prevention and control measures for patients and their caregivers to reduce nosocomial infection. The personal protection of medical personnel should also be taken seriously, and scientific measures should be implemented to guarantee their safety.

The role of TLR4 in pancreatic diseases is a research hotspot in recent years, and a large number of studies have shown that TLR4 is closely associated with pancreatic cancer. This article mainly discusses the abnormal expression and regulation mechanism of TLR4 in pancreatic cancer and its potential in cancer treatment, so as to provide new ideas for the pathogenesis and treatment of pancreatic cancer.

OBJECTIVETo investigate the clinical efficacy of laparoscopic ventriculoperitoneal shunt with temporary external drainage in the treatment of hydrocephalus.

METHODSFifty-two cases of hydrocephalus randomized into two groups to receive laparoscopic assisted ventriculoperitoneal shunt with temporary external drainage (19 male and 7 female patients) and conventional ventriculoperitoneal shunt (20 male and 6 female patients). The catheterization time in the abdominal cavity, release time of intracranial hypertension, average hospital stay, postoperative pains, and postoperative complications were compared between the two groups.

RESULTSLaparoscopic ventriculoperitoneal shunt with temporary external drainage was performed successfully in all the cases without intraoperative conversion to open surgery. Compared with the conventional ventriculoperitoneal shunt, laparoscopic ventriculoperitoneal shunt with temporary external drainage was associated with significantly shortened catheterization time in the abdominal cavity, release time of intracranial hypertension, and average hospital stay (P<0.01) as well as lowered postoperative pain score at 4, 8, 16, and 24 h after the operation. The pain scores at 48 and 72 h postoperatively were comparable between the two groups. During the follow-up 3 months, the patients receiving laparoscopic ventriculoperitoneal shunt were found to have significantly lower rates of peritoneal end obstruction and abdominal cavity infection than those having conventional shunt (3.8% vs 19.2%, P<0.01; 1.0% vs 23.1%, P<0.01).

CONCLUSIONLaparoscopic ventriculoperitoneal shunt with temporary external drainage is feasible and produces better clinical therapeutic effect for management of hydrocephalus.

ObjectiveTo investigate the clinical effect of laparoscopic splenectomy and pericardial devascularization (LSPD) in patients with portal hypertension and the long-term effect of LSPD. MethodsA total of 40 portal hypertension patients with Child-Pugh A/B liver function who received LSPD in The First Hospital of Jilin University from August to December 2017 were enrolled as surgical group, and 44 portal hypertension patients with Child-Pugh A/B liver function who received conservative treatment during the same period of time was enrolled as internal medicine group. The patients were followed up to June 30, 2019, and liver function parameters, upper gastrointestinal bleeding, and portal vein thrombosis were recorded for all patients at each time point. The t-test was used for comparison of normally distributed continuous data between two groups; an analysis of variance was used for comparison between multiple groups, and the Bonferroni test was used for further comparison between two groups. The Kruskal-Wallis H test was used for comparison of continuous data with skewed distribution; between multiple groups, and the Mann-Whitney U test was used for further comparison between two groups. The chi-square test was used for comparison of categorical data between groups. ResultsAt 6, 12, and 24 months after discharge, compared with the internal medicine group, the surgical group had a significantly higher level of cholinesterase (t=3.527, 3.849, and 5.555, all P＜0.05) and a significantly lower Child-Pugh score (t=2.498, 2.138, and 2.081, all P＜0.05). Compared with the internal medicine group at 12 and 24 months after discharge, the surgical group had a significantly higher level of albumin (t=3.120 and 2.587, both P＜0.05) and a significantly lower incidence rate of upper gastrointestinal bleeding (χ2=4.947 and 5.155, both P＜0.05). At 24 months after discharge, the surgical group had a significantly lower number of patients who had a significant increase in alpha-fetoprotein level than the internal medicine group (χ2=4.648, P=0.031). At 12 months after discharge, the surgical group had a significantly higher incidence rate of portal vein thrombosis than the internal medicine group (χ2=4.395, P=0.036). The surgical group had significant improvements in albumin (F=2.959, P=0.013), cholinesterase (F=11.022, P＜0001), prothrombin time (H=94.100, P＜0.001), and Child-Pugh score (F=3.742, P=0.003) from admission to 12 and 24 months after surgery. ConclusionIn portal hypertension patients with Child-Pugh A/B liver function, LSPD can improve liver function and reduce the incidence rate of upper gastrointestinal bleeding, and the high incidence rate of portal vein thrombosis can be effectively reduced by oral aspirin and rivaroxaban.

OBJECTIVETo evaluate the efficacy and safety of meropenem in Chinese patients, we conducted a study for the treatment of patients with lower respiratory tract infections, urinary tract infections and other infections.

METHODSA total of 182 hospitalized patients were enrolled in the study. 90 patients received 500 mg meropenem every 12 hours (or 1 g every 12 hours if necessary) and 92 patients received imipenem/cilastatin 500 mg/500 mg every 12 hours (or 1 g every 12 hours if necessary) by intravenous infusion. The duration of treatment was 7 - 14 days for both groups.

RESULTSSeventy of 90 cases receiving meropenem and 70 of 92 cases receiving imipenem/cilastatin were assessable for clinical efficacy. The overall efficacy rates were 90% for the meropenem group and 87% for the imipenem/cilastatin group, and the bacterial eradication rates were 86% in both groups. 93 (76%) of 123 strains isolated from patients produced beta-lactamases. Adverse drug reactions were evaluated in 72 cases in the meropenem group and 70 cases in the imipenem/cilastatin group. The adverse drug reaction rates were 9.7% and 8.6%, respectively. The results showed that there were no statistical differences between these two groups (P > 0.05).

CONCLUSIONMeropenem is effective and safe for the treatment of bacterial infections caused mainly by beta-lactamase-producing strains.
