General indications include: (1) HBV dna≥105 copy/M L (HBeAg negative person is ≥104 copy/ml); (2) ALT≥2xuln, such as with interferon treatment, ALT should be ≤10xuln, blood total bilirubin level should be Patients with (1) and (2) or (3) should be treated with antiviral treatment; For those who do not reach the above standard of treatment, the changes of the condition should be monitored, such as continuous HBV DNA positive, and alt abnormalities, should also consider antiviral treatment (III).

Java multithreading-prerequisites for synchronizationThe premise of synchronization must be that two or more threads must be the same lock used by all threads.In this way, only one thread can be synchronized. when running the multi-thread security issue setting synchronization, pay attention to specifying which code is multi-thread running code and what is shared data and the multi-thread running code, which statements are used to synchronize shared d

console that comes with the JDK from java5, and is used to monitor memory, threads and classes in the JVM Jvisualvm,jdk comes with an all-in-all tool to analyze memory snapshots, thread snapshots, monitor memory changes, GC changes, and More. Mat,memory Analyzer tool, An eclipse-based memory analyzer, is a fast, feature-rich Java heap Analysis tool that can help us find memory leaks and reduce memory consumption gchisto, a tool for professional analysis of GC logs Too

I said children's shoes, do not forget that we are in the Celestial Kingdom.Posted on a website, the above mentioned most of the software cracked version here should be able to download to the Watcher of LoveConclusionAs programmers we all have a concept, that is, how to simply how to be efficient how to come (in fact, lazy). Good tools can bring us more output and improve our productivity. I hope that we can make good use of some tools to complete our usual development work, I wish

If N is smaller than the "current length of" the string, the content is reduced to its A/n characters, the rest being Dr opped. If N is greater than the ' current length

First, learn about the new features added from spring2.5: These new features include annotation-driven dependency injection (Annotation-driven Dependency injection), which automatically detects spring components on classpath using annotations instead of XML metadata, and annotations support for life-cycle methods, A new web controller model maps requests to annotated methods, supports new additions to the Junit4,spring XML namespace in the test framework, and so on. 1.

Prerequisites for successful VOD systems and servers: 1. The network system should be designed so as to avoid network traffic congestion. 2. High-performance switches are tightly integrated with servers, storage systems, backup systems, software, system settings, and client settings. 3. There is a need to continuously monitor and debug the network environment, the use of the network, the throughput of devices and servers on the network. 4. Operate
