OBJECTIVETo observe the effect of Qiju Dihuang Pill (QDP) on changes of Chinese medical syndrome types in pregnant women of Gan-Shen yin deficiency syndrome (GSYDS), and to explore the correlation between imbalanced cytokine levels and GSYDS.
METHODSThis was a random controlled trail. A total of 163 pregnant women of GSYDS at 12 -16 gestational weeks were randomly allocated into the experimental group (86 cases) and the control group (77 cases). Patients in the experimental group took QDP for 2 -4 weeks. Changes of Chinese medical syndrome types and serum interferon-gamma (IFN-gamma) and interleukin-4 (IL-4) levels were observed and compared between the two groups before and after treatment.
RESULTS(1) Totally 41 patients (47.7%) in the experimental group were transformed to normal Chinese medical syndrome type. In the same period of the follow-ups, 9 patients (11.7%) in the control group were transformed to normal Chinese medical syndrome type, showing statistical difference (P < 0.05). (2) In the experimental group, the serum level of IFN-gamma and the ratio of IFN-gamma/IL-4 in the peripheral blood were obviously lower after treatment than before treatment (P < 0.01), and obviously lower than those in the control group (P < 0.01). The level of IL-4 after treatment in the experimental group was higher than that before treatment, and also higher than that in the control group, but with no statistical difference.
CONCLUSIONSThese results indicated that there was imbalanced IFN-gamma/IL-4 ratio in the peripheral blood of pregnant women of GSYDS. QDP might play a role in immunoregulation by affecting the IFN-gamma level.

Citri Fructus identification by fingerprint and chemometrics was investigated in this paper. Twenty-three Citri Fructus samples were collected which referred to two varieties as Cirtus wilsonii and C. medica recorded in Chinese Pharmacopoeia. HPLC chromatograms were obtained. The components were partly identified by reference substances, and then common pattern was established for chemometrics analysis. Similarity analysis, principal component analysis (PCA) , partial least squares-discriminant analysis (PLS-DA) and hierarchical cluster analysis heatmap were applied. The results indicated that C. wilsonii and C. medica could be ideally classified with common pattern contained twenty-five characteristic peaks. Besides, preliminary pattern recognition had verified the chemometrics analytical results. Absolute peak area (APA) was used for relevant quantitative analysis, results showed the differences between two varieties and it was valuable for further quality control as selection of characteristic components.
