CLCF1 Gene Associated With Postmenopausal Osteoporosis of Kidney Yin Deficiency Syndrome (PMOP)

March 24, 2017 updated by: xuhuijuan

CLCF1 Gene Associated With Postmenopausal Osteoporosis of Kidney Yin Deficiency Syndrome Regulating the Bone Osteoimmunology Mechanism by the OPG/RANKL/RANK Signal System

For nearly 112 million patients with osteoporosis in China, it is of great significance for preventing and treating by clearly understanding the molecular mechanism of kidney deficiency. Thus, the research group has demonstrated in the earlier research that CLCF1 is an associated gene that can regulate JAK2/STAT3 signal pathway and impact bone metabolism for kidney yin deficiency of postmenopausal osteoporosis (PMOP). To make clear understanding of the direct-acting mechanism of CLCF1 for bone metabolism, this study intends to: ①observe impacts of low expression of CLCF1 upon immunities in mice and OPG/RANKL/RANK signal system using the technology of adenovirus associated virus. ②explore impacts of over-expression and silencing of CLCF1 on B lymphocytes by culcuturing the cells together with osteoblasts. ③ analyze the impacts of treating kidney yin deficiency of PMOP by Liuwei Dihuang pill upon immunities and OPG/RANKL/RANK system, and discuss the mechanism of regulating bone metabolism by CLCF1 by OPG/RANKL/RANK system via the bridge between immune system and bone metabolism, so as to demonstrate if the hypothesis of this study that "the molecular osteoimmunological mechanism of kidney yin deficiency of postmenopausal osteoporosis (PMOP) is possibly closely related to the impacts of CLCF1 regulation of OPG/RANKL/RANK signal system on bone metabolism" is right or not.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
60

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

46 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

Female

Description

Inclusion Criteria:

  • Patients were included if they were female Han Chinese patients who had undergone natural menopause at least 2 years prior and

    • met the diagnostic criteria for osteoporosis according to the "clinical practice guidelines of traditional medicine for primary osteoporosis"
    • met the CM diagnostic criteria according to "Syndrome Differentiation in Modern Research of Traditional Chinese Medicine"
    • provided informed consent, which was approved by the Fujian Academy of Traditional Chinese Medicine Clinical Research Ethics Committee

Exclusion Criteria:

  • patients who did not meet the diagnostic criteria for osteoporosis or CM standards
  • patients with rheumatoid arthritis, diabetes, secondary osteoporosis due to hyperthyroidism, and severe cardiovascular or cerebrovascular diseases
  • patients with abnormal liver and/or Shen function test results
  • patients with osteoporosis who had received treatment with CM within the last month, hormone replacement therapy and calcitonin within the past three months, or bisphosphonates for 15 consecutive days within the past 6 months.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
