[Hydrochemical Characteristics and Control Factors of Groundwater in the Northwest Salt Lake Basin].

Taking the Tugeligaole sub-basin of the Jilantai Salt Lake Basin in Inner Mongolia as the typical study area, the groundwater samples of 22 points were collected, and their main characteristic indexes were tested during the wet season and the dry season separately in 2021. Mathematical statistics, Piper triangular diagrams, a Gibbs plot, ionic relations, and factor analysis were used to analyze and discuss the hydrochemical characteristics and formation mechanism of groundwater in different periods. Based on the evaluation of the groundwater quality using the water quality index(WQI) method, the potential risks of groundwater Cr and F were evaluated using the health risk evaluation model.

Recurrent abdominal pain due to small bowel volvulus after transabdominal preperitoneal hernioplasty: A case report and review of literature.

Background: Compared with open mesh repair, transabdominal preperitoneal (TAPP) hernioplasty results in less chronic postoperative inguinal pain and faster postoperative recovery. However, it may still lead to rare but serious complications. Here we report a case of intestinal volvulus with recurrent abdominal pain as the only clinical symptom, which occurred 3 mo after TAPP repair for bilateral inguinal hernia.

[Analysis of Nitrate Pollution Sources in the Rainy Season of the Lower Fenhe River].

Through the application of multi-isotope tracing, IsoSource model calculation, and microbial detection, the source of nitrate pollution in the lower reaches of the Fenhe River was screened, and the contribution rate of each source was calculated. The results showed that the main forms of nitrogen-containing substances in the lower reaches of the Fenhe River are NO-N and NH-N and that the NO-N content in 77.8% of the samples exceed the national drinking water standard.

[Community Composition of -type Denitrifying Bacteria in the Waters of the Lower Reaches of the Fenhe River and Its Relationship with Inorganic Nitrogen].

In order to assess the waters of the lower reaches of the Fenhe River and the interaction with inorganic nitrogen, Illumina high-throughput sequencing technology was used to analyze samples based on the analysis of water quality indicators of nine rivers. The community structure and diversity of -type denitrifying bacteria was diagnosed and statistical analysis was carried out to analyze the relationship between these communities and inorganic nitrogen content. The results show that the lower reaches of the Fenhe River are seriously polluted with inorganic nitrogen and the overall water quality standard was classified as V.

The clinical significance of CDK1 expression in oral squamous cell carcinoma.

Objectives: To evaluate the clinical significance of cyclin-dependent kinase 1 (CDK1) in 77 oral squamous cell carcinomas (OSCC) using immunohistochemical methods.

Study Design: Immunohistochemical expression of CDK1 was compared with various clinicopathological features in 77 OSCC and 60 controlled epithelia adjacent to the tumours. In addition, correlation of CDK1 expression and prognostic and the 5-year accumulative survival rate of OSCC were investigated.

[A survey on cerebral infarction/transient ischemic attack inpatients compliance with secondary stroke prevention and follow-up 90 days].

Objective: Poor compliance with evidence-based-medicine guidelines could significantly influence the effect of stroke prevention strategies. The objectives of this survey are to investigate the current status in Beijing of cerebral infarction/TIA (transient ischemic attack) inpatients' adherence to the evidence-based-medicine secondary prevention and behavior modifications both at the discharge and at 90-day follow up.

Methods: The survey included cerebral infarction/TIA patients successively admitted from 1, Oct 2006 to 1, May 2007, used ACEI/ARB, Statin, anti-platelet agents therapy, accepted carotid endarterctomy or angioplasty or stent, and modified behaviors to stop smoking and control weight.
